Description

A multifunctional maxillary sinusoscope Technical Field

The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional maxillary sinusoscope.

Background Art

When teeth are lost in the maxillary posterior region and need to be replaced with implants, if the bone height in this area is found to be insufficient to accommodate the implant, a maxillary sinus lift is required to separate the sinus floor mucosa from the sinus floor bone wall and to graft bone in this separated space, thereby raising the sinus floor bone height. Only after obtaining sufficient bone height can subsequent implant placement be completed. However, maxillary sinus lift surgery is generally performed under blind vision, and perforation of the sinus floor mucosa is prone to occur. After perforation, the maxillary sinus surgery may easily fail, and may also easily cause maxillary sinus infection and even affect implant bone healing, increasing the risk of implant surgery failure. In order to reduce the probability of maxillary sinus mucosal perforation, endoscope-assisted maxillary sinus lift surgery was proposed and applied after the 1990s.

An analysis of current endoscopically assisted sinus lift procedures reveals the following key shortcomings: 1. There is no multifunctional endoscope specifically designed for both observation and manipulation. 2. Most existing endoscopically assisted sinus lift procedures use the nasal approach, which can cause additional surgical trauma to implant patients. 3. In existing endoscopically assisted sinus lift procedures, the endoscope and lift instruments are generally not able to enter the surgical area simultaneously, preventing simultaneous observation and manipulation. Some procedures require two separate operators, requiring significant manpower and making them impractical for a single person.

Summary of the Invention

The core problems of the existing instruments include: 1. The observation and operation of the existing instruments are completed by two different instruments, and the observation and operation cannot be carried out simultaneously; 2. The entry route of the existing instruments is the nasal cavity, and some are the lateral wall of the maxillary sinus or the top of the alveolar ridge. It is impossible to take into account multiple entry methods with one set of instruments; 3. The existing nasal endoscopes of the ENT department are often borrowed for maxillary sinus lift surgery, which do not have the functions of lateral observation, irrigation, air jet and negative pressure suction; 4. The existing instruments cannot achieve large-scale maxillary sinus floor mucosal stripping; 5. The existing instruments cannot strip the mucosa of complex structural areas (such as the maxillary sinus septum or the inner wall of the maxillary sinus); 6. The current observation and operation tools are large, and there is no set of observation and operation tools that can complete the implant placement through the lift operation hole after the maxillary sinus lift is completed.

In response to one or more of the above problems, the present invention describes a multifunctional maxillary sinusoscope that integrates operation functions, video acquisition functions, liquid spraying functions, air jet functions, and negative pressure suction functions into a thin tube body that can pass through a prepared bone hole, thereby achieving safer and more effective surgical treatment.

Specifically, the present invention describes a multifunctional maxillary sinusoscope, which comprises: a main body, the main body comprising a main body body portion and a main body top operating end,

The top operating end of the main body is used to pass through a bone hole prepared in the upper jaw of a human or animal body to enter the surgical area for operation; characterized in that the diameter of the top operating end of the main body is less than 6mm;

The top operating end of the main body includes:

Video acquisition module, used to observe the surgical field during surgery;

Data cable channel, used for setting data cables for data transmission;

An operating channel, used to guide the operating components into the operating area for operation;

A spray channel for spraying water on the surgical area;

Air jet channel for air jetting the surgical area;

Negative pressure channel, used to extract blood generated during operation and liquid generated during flushing of the surgical area under negative pressure;

The paths of the data cable channel, the liquid spray channel, the air jet channel, the negative pressure channel and the operation channel in the main body are continuous with the paths in the operation end at the top of the main body;

By setting up data cable channel, liquid spray channel, air jet channel, negative pressure channel and operation channel at the top operation end of the main body, the video acquisition function, flushing function, air jet function, negative pressure suction function and operation function are integrated into a diameter less than 6mm. Inside the operating end of the main body, safe operation of the surgical area can be completed under video acquisition conditions.

Furthermore, the negative pressure channel and the operating channel are integrated into one channel, which is defined as the negative pressure operating channel;

The cross-sectional area of the negative pressure operating channel accounts for 50% or more of the cross-sectional area of the main body;

The diameter of the operating end of the main body is not less than the diameter of the main body;

An operation inlet is provided on the main body for the operation tool to enter; the operation inlet is connected to the negative pressure operation channel; the pressure in the negative pressure operation channel can be adjusted by adjusting the size of the operation inlet;

The end of the top operating end of the main body that first enters the surgical area is the first end; the other end opposite to the first end is the second end. The first end of the top operating end of the main body is the total outlet end; the total outlet end includes the outlets of the data cable channel, the liquid spray channel, the air jet channel and the negative pressure operation channel.

Furthermore, the operation on the lateral tissue is completed by arranging the main outlet on the side of the main body, and the negative pressure operation outlet is used as an example for explanation. The specific solution is: the operation component is used to extend into the surgical area in the side direction of the main body to perform the operation under the guidance of the negative pressure operation channel and the negative pressure operation outlet and the image guidance of the video acquisition module (2).

Furthermore, by giving priority to the negative pressure operation outlet through the video acquisition module to enter the operating area, it is ensured that subsequent operations are performed only after the situation in the operating area is observed first, thereby avoiding mucosal damage caused by improper entry. The specific solution is: the video acquisition module includes a camera device and a signal line; the camera device and the negative pressure operation outlet are both arranged at the first end of the main body, and when entering the operating area along the operation path, the video acquisition opening enters the operating area before the negative pressure operation outlet; in addition, the camera is embedded in the top operating end of the main body of the main body and is connected to the back-end power supply and video display device through wires and transmission lines.

Furthermore, the side opening is ensured by arranging the front operating section of the mirror to be perpendicular to the main body of the main tube.

Furthermore, by limiting the length of the main body portion, it is ensured that it has sufficient penetration strength under a thinner tube diameter; and in order to meet the needs of short-path and small-operation entrance diameter surgery; the specific technical solution is: the main body portion length range is 0.4-20cm; further, it is set to 0.4-10cm; the main body portion is set to a hard tube body, such as a hard plastic or metal tube body, to further ensure the tube body strength when penetrating the operation path and after entering the surgical area.

Furthermore, convenience of operation of the main body is achieved by providing a handheld sleeve at the second end of the main body; the specific technical solution is: the maxillary sinusoscope includes a handheld sleeve for holding to complete the operation; further, the main body is connected to the channel in the handheld sleeve; further, the main body is connected to the handheld sleeve at an angle; further, the handheld sleeve is larger than the main body, and a channel consistent with the main body is provided in the handheld sleeve.

Furthermore, the above-mentioned maxillary sinus mirror is produced according to the problems of the maxillary sinus, but its application is not limited to performing maxillary sinus-related surgeries. Specifically, it can also be used for: maxillary sinus stripping, maxillary sinus foreign body clamping, apical surgery, broken root canal needles, puncture sampling, displaced broken root clamping; temporomandibular joint endoscopy; diagnosis and treatment of lateral root canal puncture; treatment of jaw cysts; observation operating mirror for pathological biopsy, external auditory canal cleaning surgery, etc.

Furthermore, a control box is installed to operate and implement various functions within the main body channel. Specifically, the main body is connected to the control box via a connecting tube. The control box controls the flushing action and the video acquisition module. The control box is then connected to the flushing device and the video acquisition terminal. The result is a system that effectively completes the observation and operation of the maxillary sinus.

The advantages of the present invention are as follows:

1. The present invention adopts an ingenious structural arrangement. The video acquisition module is arranged in the middle of the upper semicircle of the main body (viewed from a cross-sectional perspective), and a liquid spray channel and an air jet channel are respectively arranged on both sides of the main body. Then, a negative pressure channel is arranged in the lower semicircle. The operation channel is preferably integrated into the negative pressure channel, achieving maximum space compression. It can complete multiple functions such as operation, observation, flushing, and air jet through a single instrument, solving the problem that one person cannot complete observation and operation simultaneously. It can also solve the problem of flushing, air jet and negative pressure suction during maxillary sinus surgery without changing instruments. In addition, through a thin main body, it can be applied to various surgeries such as maxillary sinus surgery, especially suitable for surgical methods such as transalveolar crest approach.

2. By arranging the main outlet on the side of the main body, the negative pressure operation outlet on the main outlet is also arranged on the side of the main body along with the main outlet, so that the operation on the lateral surgical area can be effectively completed, which is especially suitable for the stripping operation of the maxillary sinus mucosa, and can achieve a large range of mucosal stripping of the maxillary sinus floor.

3. By dividing the maxillary sinusoscope into a main body portion and a handheld cannula connected to the main body portion at an angle, and by making the handheld cannula larger than the main body portion, the operation convenience of the entire maxillary sinusoscope can be increased by operating the handheld cannula while ensuring that the main body portion is thinner.

4. By setting up a video acquisition module, various operations can be completed under visualization, making the operating tools and endoscope functions highly integrated, greatly reducing the blindness of the operation. The camera is embedded in the top operating end of the main body of the main body. Its image clarity is higher than the optical fiber transmission image endoscope equipment currently used in clinical practice. It can also take pictures and videos during the operation and transmit them to the video in real time. The display device allows not only the operator but also observers to clearly see the surgical operations and key steps, which is helpful for medical education.

5. The maxillary sinusoscope of the present invention can be applied to a variety of actual operation situations. The operation components can be replaced at will according to actual needs. The stripping components of different lengths and diameters can also be selected according to needs. In addition to meeting the needs of the oral cavity, it can also enter the sinuses through the mouth to perform nasal cavity-related operations; in addition, it can also be used in any application scenario with a short and thin operation path. The operation tools can be selected according to needs to eliminate the problem of limited and single functions.

DETAILED DESCRIPTION

The following is a clear and complete description of the technical solutions in the embodiments of the present invention through specific embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the present invention All other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

1-8, a maxillary sinus mirror comprises: a main body 1, which includes a main body body portion 161 and a main body top operating end 15,

The top operating end 15 of the main body is arranged at the top of the main body body portion 161 and is used to pass through the bone hole prepared in the upper jaw of a human or animal body to enter the surgical area for operation; the diameter of the top operating end 15 of the main body is less than 6mm; more preferably, less than 4mm.

The main body top operating end 15 includes:

Video acquisition module 2, which includes a camera and signal lines; used to observe the surgical field during surgery;

Data cable channel 12;

An operating channel, used to guide the operating components into the operating area for operation;

The liquid spray channel 13 is used for spraying water to flush the surgical area;

The jet channel 14 is used to jet the surgical area; the jet is used to fill the surgical area;

Negative pressure channel, used to extract blood generated during operation and liquid generated during flushing of the surgical area under negative pressure;

The paths of the data cable channel 12, the liquid spray channel 13, the air jet channel 14, the negative pressure channel, and the operation channel in other parts of the main body 161 are continuous with the operation end 15 at the top of the main body;

By arranging a data cable channel 12, a liquid spray channel 13, an air jet channel 14, a negative pressure channel, and an operation channel 11 at the top operation end 15 of the main body, the video acquisition function, the flushing function, the air jet function, the negative pressure suction function, and the operation function are integrated into the top operation end 15 of the main body with a diameter of less than 6 mm, so that safe operation of the surgical area can be completed under video acquisition conditions.

A more preferred embodiment is as follows: the diameter of the top operating end 15 of the main body is not smaller than the diameter of the other parts of the main body body 161; this size setting can meet the diameter requirements of the top operating end 15 of the main body, and the other parts can be smaller than the top operating end 15 of the main body.

In the embodiments of the present invention, the diameter of the main body top operating end 15 is the same as that of the main body body portion 161. In specific implementation, the main body body portion 161 is a rigid straight pipe.

When implants, such as dental implants, are placed simultaneously after a sinusoscope procedure, the bone cavity must be smaller than the implant diameter to ensure initial implant stability. The diameter of the main body 161 is slightly smaller than the bone cavity diameter. This sizing ensures smooth sinusoscope procedures. Currently, the diameter of the implant protruding into the bone is typically approximately 3.0-5.5 mm. The diameter of the main body 161 can range from, but is not limited to, 2.8 mm to 5.3 mm.

In specific implementation, the goal of increasing the working space of each channel is achieved by integrating any two channels, ensuring the effective execution of the operation. Preferably, the negative pressure channel and the operation channel are integrated into one channel, defined as the negative pressure operation channel 11; wherein the negative pressure operation channel 11 occupies half or more of the cross-sectional area of the main body 1; more preferably, the liquid spray channel 13, the air jet channel 14, and the data cable channel 12 occupy half of the cross-sectional area of the main body 1 of the main body portion 161; and the negative pressure operation channel 11 occupies half of the cross-sectional area of the main body 1. This arrangement can prioritize the required working space for the operation, as well as the space required for negative pressure aspiration of blood and viscous liquids generated during flushing. Furthermore, by simultaneously integrating the liquid spray channel 13, the air jet channel 14, and the negative pressure operation channel 11 into the main body portion 161, it is possible to simultaneously achieve negative pressure aspiration of viscous liquids in the surgical area while flushing the surgical area, thereby ensuring a clear surgical field. This makes it suitable for various surgical situations involving a large amount of blood, exudate, and inflammatory tissue in the surgical area. Preferably, the cross-sections of the main body portion 161 and the main body top operating end 15 are both circular or elliptical.

More preferably: define the end of the main body part 161 that first enters the surgical area as the top of the main body part 161, and the other end of the main body part 161, that is, the tail of the main body part 161, is defined as the end expansion part 164 of the main body; a main body top operating end 15 is provided at the top of the main body 1, and a total outlet 151 is provided on the operating end, and the plane where the total outlet 151 is located is the main outlet surface 152, and the position of the main outlet surface 152 relative to the main body part 161 is defined as the front part of the main body part 161; the total outlet 151 includes the outlets of the data cable channel 12, the spray channel 13, the jet channel 14, and the negative pressure operation channel 11; the total outlet 151 is a plane; the channel paths of the data cable channel 12, the spray channel 13, the jet channel 14, and the negative pressure operation channel 11 in the main body part 161 are consistent.

More preferably, the outlet of the negative pressure operation channel 11 on the top operating end 15 of the main body is a negative pressure operation outlet 112, and the negative pressure operation outlet 112 is not facing the direction directly opposite the top of the main body body 161, that is, the end face normal direction of the top operating end 15 of the main body forms a certain angle with the axis of the main body body 161, preferably 45°-180°, more preferably 90°.

Under the guidance of the negative pressure operation channel 11 and the negative pressure operation outlet 112 , the operating component enters the top operating end 15 of the main body in the non-top facing direction to operate.

During use, the main body 161 is sent into the surgical area through the prepared bone hole, and then the operating tool (such as a stripping wire) is guided by the negative pressure operating channel 11 and the negative pressure operating outlet 112, and extended from the operating end 15 at the top of the main body (preferably from its lower half) along the negative pressure operating outlet 112 to complete the corresponding operating action as needed.

In a more preferred embodiment, the video capture module 2 includes a camera device with an illumination structure 22, which includes an integrated camera module 21 and an illumination structure 22. The illumination structure 22 is located on one or both sides of the camera device; the camera device and the negative pressure operating outlet 112 are both located on the main outlet surface 152 of the top operating end 15 of the main body. When entering the surgical area along the operating path, the camera device enters the surgical area before the negative pressure operating outlet 112. This arrangement ensures that after entering the surgical area, the surgical area can be observed as quickly as possible, and adjustments can be made based on the observed situation to avoid unnecessary tissue damage. This protective effect is particularly significant for the thin mucosa at the floor of the maxillary sinus.

More preferably, the camera device and the negative pressure operation outlet 112 are respectively arranged at different positions of the main outlet surface 152 at the top operation end 15 of the main body, the two do not overlap and are arranged longitudinally, which can ensure that the operation area can be observed first with the smallest entry path, thereby avoiding damage to the greatest extent.

More preferably, with reference to FIG5 , the orientation of the camera device is consistent with the orientation of the negative pressure operation outlet 112; the camera device is consistent with the longitudinal center axis 153 of the negative pressure operation outlet 112. This can ensure that the video acquisition module 2 can capture the field of view facing the surgical area and reduce observation errors. With reference to FIG10 and FIG11 , a receiving cavity 192 for the camera device is provided at the top operating end 15 of the main body; the video acquisition module 2 is embedded in the receiving cavity 192. The embedded setting method can ensure that the camera is fixed inside the top operating end 15 of the main body.

This arrangement ensures that even significant bends will not affect the normal recording of the front-end video capture module 2. This approach, combined with the angled arrangement of the main body portion 161 and the handheld sleeve 162, solves the problem of how to install the video capture module 2 in a channel with significant bends. The camera module 21 and the lighting assembly are arranged horizontally; the lighting structure 22 is arranged on the left and right sides of the camera module 21. This arrangement ensures that the surgical area can be observed at the minimum entry distance. Note: The horizontal direction is perpendicular to the axial direction of the main body 1.

The frontmost portion of the top operating end 15 of the main body is the total outlet 151, which includes the negative pressure operating outlet 112. The plane where the total outlet 151 terminates is defined as the main outlet surface 152 of the top operating end 15 of the main body; the channel in the top operating end 15 of the main body corresponds to and is connected to the channel of the main body 1; the overall diameter of the top operating end 15 of the main body is consistent, and the diameter of the top operating end 15 of the main body is not less than the diameter of the main body 1. The outer wall where the top operating end 15 of the main body passes with the main body 1 is provided with a rounded corner, which can effectively avoid scratching of the tissue; more preferably, the main body 1 is cylindrical or elliptical; the total outlet 151 on the top operating end 15 of the main body is perpendicular to the longitudinal axis of the main body 1, and the main outlet surface 152 is tangent to the cylindrical surface of the main body body 161. This arrangement ensures that the size of the main body 1 will not change due to the setting of the side total outlet 151, ensuring that the entire instrument entry process is smooth.

More preferably, referring to FIG15 , the negative pressure operating channel 11 extends along the longitudinal axis of the main body portion 161 through the main body connection portion 163 , turns to the main body top operating end 15 at the top of the main body 1 , and terminates at the negative pressure operating outlet 112 . The negative pressure operating channel 11 within the main body 1 has a uniform size, or is slightly enlarged at the main outlet 151 . This arrangement ensures continuity and consistency during the operation of the operating tool.

The operating system includes a negative pressure operating channel 11 in the main body 1 and the operating tools accommodated therein; the video acquisition and display control system includes a camera module 21, an illumination structure 22, a data cable channel 12 in the main body 1, a data cable extension tube 183, a data cable connecting tube 1853, a control box 41, and a video display device 42 and its switch; the control box 41 and the video display device 42 can transmit real-time images via a wired or wireless network; the liquid spray system includes a liquid spray channel 13 in the main body 1, a liquid spray extension tube 181, a liquid spray connecting tube 1851, a control box 41, a liquid supply device 43 and its switch; the liquid supply device 43 is controlled by a switch; the air jet system includes an air jet channel 14 in the main body 1, an air jet extension tube 182, an air jet connecting tube 1852, a control box 41, an air supply device 44 and its switch; the air supply device 44 is controlled by a switch; the negative pressure system includes the negative pressure operating channel 11 in the main body 1, the lower cavity in the hand-held sleeve 162, the negative pressure extension tube, the negative pressure connecting tube 184, the negative pressure device 45 and its switch.

Referring to Figure 1 , the main body 1 has four channels. The largest channel, occupying approximately half of the main body's cross-sectional area, is the negative pressure operating channel 11. The remaining three channels are the left and right channels: a liquid spray channel 13 and an air jet channel 14. The center channel houses the video capture module 2 and its data cable channel 12. Specifically, the liquid, gas, and data cable channels 12 of the main body 1 respectively carry liquid, gas, and data cables.

Referring to Figure 1, the operating tool may be a stripping component 31 made of nickel-titanium wire with shape memory function. At this time, it is bent into two strands, enters from the operating inlet 111, ascends along the negative pressure operating channel 11, and extends forward and downward from the negative pressure operating channel 11 of the total outlet 151. The stripping component 31 is an irregular circle, and operating handles 311 are set at both ends of the stripping component 31 with shape memory to facilitate pulling out the stripping component 31 with shape memory to control the stripping of the mucosa by the stripping component 31.

More specifically, the stripping component 31 can use a temperature-controlled memory wire with shape memory. When the temperature is lower than body temperature (for example, 20°C), the memory wire is a large amount of twinned monoclinic martensite phase at the microscopic level. At this time, the memory is weak, the elasticity is low, and the hardness is small. It can be easily bent into two strands with a small diameter at the bend, and it can be smoothly contracted into the negative pressure operation channel 11, making it easier to enter the negative pressure operation channel 11. After entering the body during surgery (at about 37°C), the microstructure of the stripping component 31 changes due to the higher temperature in the body, specifically from the martensite phase to the austenite phase with a cubic structure. At this time, the memory of the stripping component 31 becomes stronger, the elasticity becomes higher, the hardness becomes greater, and there is a memory trend of returning to its original shape. A shape memory effect occurs and a continuous and stable supporting force is generated. The diameter of the bend becomes larger, forming a larger stripping area, which is conducive to the stripping of the mucosa.

More preferably, warm water of varying temperatures can be supplied through the spray channel 13 as needed. If thick or tough mucosa is observed, the exfoliation assembly 31 can be flushed with human-tolerable warm water to further generate more austenite, thereby enhancing the elasticity of the exfoliation assembly 31 and facilitating exfoliation of thick and tough mucosa. If the mucosa is thin and brittle, the exfoliation assembly 31 can be flushed with human-tolerable low-temperature water or sprayed with air to partially transform the austenite into martensite, reducing its elasticity and minimizing damage to thin and brittle mucosa. By controlling the temperature and changing the memory and elasticity of the memory wire without changing the instrument, smooth exfoliation of the surgical mucosa can be achieved.

The liquid spray channel 13 and air jet channel 14 within the main body 1 are connected to a liquid supply device 43 and an air supply device 44, respectively, via a control box 41. The control box 41 adjusts the flow rate. At the main body 1's main outlet 151, lateral liquid spray channels 172 and lateral air jet channels 174 flush the video capture module 2, while forward liquid spray channels 171 and forward air jet channels 173 flush the surgical area.

The data cable in main body 1 is connected to the power supply via control box 41, which controls the parameters of camera module 21 and lighting structure 22. Images of the surgical site captured by video acquisition module 2 are input into control box 41 and transmitted via the wireless network established by control box 41 to video display device 42 for real-time display. This allows the surgeon to perform procedures under visual conditions, effectively improving surgical efficiency and avoiding the risk of maxillary sinus mucosal damage and perforation caused by blind surgery.

The control box 41 uniformly completes the regulation of liquid spraying, air jetting, and video acquisition, and can complete the foot-operated control of liquid spraying, air jetting, taking pictures and recording videos through the foot control switch 46.

The following are the surgical options for maxillary sinus floor mucosal lift:

Depending on the location of the sinus floor, a bone cavity is created in the nearest, appropriate area of the maxillary lateral wall or the crest of the maxillary alveolar ridge to expose the sinus floor mucosa. Sinus floor lifts performed using a sinusoscope can be categorized into four methods: instrumentation, hydraulics, pneumatics, and a combination of these three.

Option 1: Instrumental operation of maxillary sinus lift

Under video capture conditions, the stripping assembly 31 is used to strip the maxillary sinus floor mucosa within the maxillary bone cavity and rinse the surgical area. The top operating end 15 of the main body is slowly lowered into the bone cavity (at this time, the stripping assembly 31 is hidden in the negative pressure operating channel 11). When the top operating end 15 of the main body reaches the surgical area, the operation is monitored by the video capture module 2. When the operating tool is a stripping assembly 31 with shape memory, the stripping assembly 31 is extended forward or forward and downward from the outlet of the negative pressure operating channel 11 below the top operating end 15 of the main body. The stripping assembly can be rotated by rotating the main body 1, or by operating the operating handles 311 on both sides to telescope in the same or opposite directions, or by rotating the operating handles 311 on both sides to flip the position of the stripping assembly. A combination of operations can also be performed to meet the requirements for stripping the mucosa in various areas of the maxillary sinus floor. During the operation, the surgical area and the lens surface are cleaned with liquid and air jets.

Option 2: Hydraulic operation of maxillary sinus lift

Under the condition of video acquisition, the spray function of the maxillary sinus mirror can be used alone, and the hydraulic pressure formed by the spray can be used to complete the maxillary sinus floor mucosa lifting surgery: turn off the negative pressure device 45, and slowly put the top operating end 15 of the main body into the bone hole to reach the surgical area. The top of the main body 1 plays a role in roughly closing the bone hole while satisfying the observation of the video acquisition module 2, and the negative pressure operation outlet 112 of the top operating end 15 of the main body is still facing the side wall of the bone hole and has not entered the maxillary sinus cavity. At this time, by controlling the liquid supply device 43, the liquid sprayed from the opening of the spray channel 13 on the main outlet surface 152 forms hydraulic pressure between the maxillary sinus floor mucosa and the maxillary sinus floor bone wall. As the spray volume increases, the hydraulic pressure gradually increases, which can further separate the maxillary sinus floor mucosa around the bone hole from the sinus wall. At this time, the main body 1 can be slowly rotated or fixed until the maxillary sinus floor mucosa lifted by the hydraulic pressure reaches a predetermined height.

Option 3: Pneumatic operation of maxillary sinus lift

Under the condition of video acquisition, the jet function of the maxillary sinus mirror can be used alone, and the air pressure generated by the jet can be used to complete the maxillary sinus floor mucosa lifting surgery: turn off the negative pressure device 45, and slowly put the top operating end 15 of the main body into the bone hole to reach the surgical area. The top of the main body 1 plays a role in roughly closing the bone hole while satisfying the observation of the video acquisition module 2, and the negative pressure operation outlet 112 of the top operating end 15 of the main body is still facing the side wall of the bone hole and has not entered the maxillary sinus cavity. At this time, by controlling the air supply device 44, the gas ejected from the opening of the jet channel 14 on the main outlet surface 152 forms air pressure between the maxillary sinus floor mucosa and the maxillary sinus floor bone wall. As the jet volume increases, the air pressure gradually increases, which can further separate the maxillary sinus floor mucosa around the bone hole from the sinus wall. At this time, the main body 1 can be slowly rotated or fixed until the maxillary sinus floor mucosa lifted by the air pressure reaches a predetermined height.

Option 4: Combined operation of maxillary sinus lift

The above three schemes are combined in the form of no less than any two operation schemes.

The following are cases where the maxillary sinus or other parts of the body or other tissues contain cysts, polyps, pus or other lesions or foreign bodies, which are suitable for implementation using this device. The following embodiments take the maxillary sinus as an example, but are not limited to the maxillary sinus.

For example, when lesions or foreign bodies such as cysts, polyps, or pus are present within the maxillary sinus, a window is opened at a suitable location on the outer wall of the maxillary bone, based on the location of the maxillary sinus cavity, to expose and incise the maxillary sinus mucosa. The top operating end 15 of the main body is placed into the maxillary sinus cavity. Under the monitoring of the video acquisition module 2, the surgical area is inspected and the location of the lesion is determined. A maxillary sinusoscope is used to perform surgery on the lesion or foreign body within the maxillary sinus. The surgery is performed using various operating tools extended from the negative pressure operating channel 11. Depending on the operating tool, no fewer than nine specific operating methods can be used: Options 5 to 13.

Option 5: Operation using puncture and injection assembly 32

When there is a lesion in the maxillary sinus that requires puncture and injection, the puncture and injection assembly 32 is moved from the top operating end 15 of the main body 1 to the site to be punctured and injected (see Figures 1 and 18). The sampling site is inspected under the monitoring of the video acquisition module 2 to fully understand the size, shape, boundary, blood vessels, etc. of the lesion. The puncture and injection assembly 32 extends through the operating inlet 111 along the negative pressure operating channel 11 to the negative pressure operating outlet 112. The length of the assembly is adjusted to the target position, and the main body 1 is adjusted to puncture the lesion tissue from different angles. The surgical area is cleaned by spraying liquid, air, and using the negative pressure suction effect in the negative pressure operating channel 11. The specimens obtained by puncture can be pathologically examined by smear or liquid-based cytology. In this solution, drug injection and other operations can also be performed on the lesion site.

Solution 6: Operation method using clamping assembly 33

When there is necrotic tissue or foreign matter in the maxillary sinus, the clamping assembly 33 is extended from the top operating end 15 of the main body 1 into the vicinity of the foreign matter in the maxillary sinus (refer to Figures 1 and 19). Under the monitoring of the video acquisition module 2, the control box 41 controls the liquid supply device 43 and the gas supply device 44 to flush and clean the surgical area and the video acquisition module 2 with liquid and/or gas respectively to ensure a clear surgical field. The location of the foreign matter is determined, and then the clamping assembly 33 is extended along the operating inlet 111 and the negative pressure operating channel 11 to the negative pressure operating outlet 112. The operating handle 311 is manipulated to clamp the foreign object and slowly pulled out of the body along with the operating end 15 at the top of the main body 1 .

In this solution, the clamping assembly can also be replaced with a cutting assembly 34 and a twisting assembly 35 to achieve corresponding surgical treatment.

Solution 7: Operation method of using the set component 36

When a foreign object, such as a broken root, falls into the maxillary sinus, the extraction assembly 36 is inserted into the maxillary sinus from the operating end 15 at the top of the main body 1 (see Figures 1 and 22). Under the monitoring of the video acquisition module 2, the control box 41 controls the liquid supply device 43 and the gas supply device 44, so that the liquid and/or gas are used to flush and clean the surgical area and the video acquisition module 2 respectively to ensure a clear surgical field. The location of the foreign object is determined, and the extraction assembly 36 is then extended along the operating inlet 111 and the negative pressure operation channel 11 to the negative pressure operation outlet 112. The operating handle 311 is manipulated to extract the foreign object and slowly pulled out of the body along the operating end 15 at the top of the main body 1.

In addition, the device can also be used in the following scenarios: when there is earwax or foreign matter in the external auditory canal, the device of the present invention can be used to remove it.

Option 8: Operation method using electrosurgical unit 37

When polyps or other lesions exist in the sinus cavity, the electric knife assembly 37 can be extended from the outlet of the negative pressure operation channel 11 below the top operating end 15 of the main body 1 to the vicinity of the polyps or other lesions.

Option 9: Operation method using laser assembly 38

When there are certain lesions in the maxillary sinus cavity that are suitable for laser surgery, the laser assembly 38 with a laser head can be extended from the negative pressure operation channel 11 below the top operating end 15 of the main body 1, aimed at the surgical area, and laser treatment can be performed on the surgical area (refer to Figures 1 and 24).

Option 10: Operation using ultrasonic component 39

When there are certain lesions in the maxillary sinus cavity that are suitable for surgery using ultrasonic instruments, the ultrasonic component 39 with an ultrasonic vibration end can be extended from the negative pressure operation channel 11 below the top operating end 15 of the main body 1 and operated on the surgical area (refer to Figures 1 and 25).

Solution 11: Joint application component operation

The combination of any two or more of the above operation schemes is a joint application component operation method.

The above embodiments are only for understanding the present invention. It should be noted that, for those skilled in the art, several improvements can be made to the present invention without departing from the principles of the present invention, and these improvements will also fall within the scope of protection of the claims of the present invention.
