A device for practicing laryngoscopy

technical field

The invention relates to the field of laryngoscopes, in particular to a device for practicing laryngoscope surgery.

Background technique

Laryngoscopy is a delicate surgery to treat vocal cord lesions through a laryngoscope, and it is also a minimally invasive surgery. During surgery, a laryngoscope is inserted through the mouth into the patient's larynx, and a microscope located outside the body magnifies the vocal cord lesions inside the larynx. The key to this type of surgery is to maintain the stability and precision of the doctor's operation. During the operation, the distance between the microscope and the vocal cord lesions is about 40cm, which requires the use of a long-handled instrument with a length of about 25cm. At the same time, the vocal cord structure is fine, and the length is only about 2cm. Precise cutting, suturing and other operations can be performed under the microscope. Because the operator's forearm is suspended and the instruments are long handles, the muscles are prone to fatigue during fine operation, the instruments cannot be held stably, and it is easy to produce jitter, etc., and fine operations cannot be performed; at the same time, because the surgical procedures are all operated under the microscope, which is different from the conventional naked eye. Surgery requires adaptation after training. It is very difficult for doctors who have just learned this kind of operation, and it usually takes more than 5 years of clinical experience to master this kind of operation.

Therefore, in order to shorten the training process and train qualified laryngoscope surgeons, a device for practicing laryngoscope surgery is urgently needed.

SUMMARY OF THE INVENTION

In order to solve the above technical problems, the present invention provides a device for laryngoscopy operation practice, which provides a simulation training platform for laryngoscopy operation, which is convenient for doctors to practice laryngoscopy operation outside the human body.

To achieve the above object, the present invention has adopted the following technical solutions:

A device for practicing laryngoscope surgery, comprising a base, a first positioning structure arranged on the base for fixing the position of the laryngoscope, and a second positioning structure arranged on the base for fixing the position of the laryngoscope;

The first positioning structure and the second positioning structure cooperate with each other, so that the laryngoscope can be directed to the inside of the laryngeal tube.

Preferably, the first positioning structure is provided with a clamping groove for placing the laryngoscope, and the laryngoscope is obliquely arranged in the clamping groove.

Further preferably, the first positioning structure includes a first support plate and a second support plate vertically arranged on the base, and the card slot is located at the top of the first support plate and the second support plate;

The second support plate is located at a position between the first support plate and the second positioning structure, and the height of the contact position between the clamping groove of the first supporting plate and the laryngoscope is greater than that of the clamping groove of the second supporting plate and the laryngoscope. The height at the contact location.

Further preferably, the clamping groove is an inverted trapezoid or V-shape, and friction-increasing components are provided on the groove walls on both sides of the clamping groove along the groove depth direction.

Preferably, the second positioning structure comprises a support plate disposed on the base and a sleeve column disposed on the end surface of the support plate facing the laryngoscope, and the throat tube is sleeved on the outside of the sleeve column.

Further preferably, the sleeve column and the laryngoscope arranged in the clamping groove on the first positioning structure are both inclined and arranged, and the inclination of the laryngoscope is adapted to the inclination of the sleeve column.

Preferably, the device further comprises a smoking structure communicated with the throat.

Further preferably, along the side of the sleeve facing the laryngoscope to the inside of the sleeve, a cavity communicated with the smoking structure is opened, and the smoking structure communicates with the throat through the cavity.

Further preferably, the smoking structure includes a smoker, a smoke guide pipe that communicates with the smoker, an intubation tube located at the tail of the smoke guide pipe and communicated with the smoke guide pipe; the upper surface of the sleeve is provided with an insertion hole. , the end of the cannula is inserted into the inside of the socket.

Preferably, a first pendant and a second pendant are arranged on the base, fasteners are arranged around the outside of the throat tube and the laryngoscope, and the fasteners of the throat tube are fixed on the first pendant, so The fastener of the laryngoscope is fixed on the second pendant.

The beneficial effects of the present invention are as follows:

(1) During laryngoscopy, the doctor inserts the laryngoscope into the patient's throat. For doctors who are just beginning to learn to do this operation, they need to practice this operation outside the human body to achieve the purpose of clinker operation. Therefore, the present invention provides a laryngoscope surgery training device, which includes a first positioning structure and a second positioning mechanism. When the doctor practices the operation through the exercise device, the laryngoscope is fixed on the first positioning structure, the laryngoscope is sleeved on the second positioning structure, and the laryngoscope is pointed to the laryngeal tube, so as to simulate the positional relationship between the laryngoscope and the laryngeal tube. The simulated positional relationship is consistent with the actual positional relationship of the operation, so that it is convenient for the doctor to practice the operation on the exercise device.

(2) The clamping slot is an inverted trapezoid or V-shaped. Due to the different upper and lower widths of the inverted trapezoidal or V-shaped, laryngoscopes with different widths can be fixed in the clamping slot, thereby increasing the use range of the exercise device.

The friction-increasing parts are arranged on the groove walls on both sides of the clamping groove, on the one hand, the clamping groove can prevent the laryngoscope from scratching, and on the other hand, the laryngoscope can be better fixed, and the laryngoscope can be prevented from falling.

(3) In actual laryngoscopy, either conventional instruments such as microscissors and forceps can be used for laryngoscopy, or laser equipment can be used for laryngoscopy. The latter will generate smoke during the operation, so that the doctor cannot see the lesions in the throat, which affects the normal operation of the operation. In addition, the smoke generated will also pollute the environment of the operating room. Therefore, in the actual laryngoscopy operation, a laryngoscope with a smoking structure or a smoking device is used to solve the above problems. In addition, the smoker is connected to the laryngoscope, and the smoker connected to the laryngoscope and the laryngoscope with the smoking structure are both complicated in structure, so it is inconvenient for doctors to take them out of the operating room to practice laryngology. mirror surgery.

In the exercise device of the present invention, the smoking device and the laryngoscope are independent of each other, so as to replace the smoking device connected to the laryngoscope and the laryngoscope with smoking structure. When the laryngoscope simulated operation is performed by the training device of the present invention, the smoker in the animal's throat is sucked away from the cavity opened along the sleeve column. It can be seen from the above analysis that although the smoking device of the device is different from the smoking device used in the actual operation, it can still remove the smoke generated during the laryngoscopy operation, and it is convenient for the doctor to take the device out of the operating room to practice the operation.

(4) The pendant and the fastener cooperate with each other, which can fix the laryngoscope and the laryngoscope, and facilitate the simulated operation of the laryngoscope.

(5) In actual laryngoscopy surgery, when using laser equipment for laryngoscopy surgery, in order to prevent the laser from causing damage to the non-surgical area, it is necessary to place saline cotton balls in the non-surgical area. Secondary damage caused by laser penetration.

When the training device of the present invention is used for laryngoscope simulation operation, the laser will not only destroy the training device, but also cause harm to the doctor who performs the laryngoscope simulation operation. In order to solve the above problems, adding saline cotton balls into the sleeve column can not only prevent the injury of the laser to the doctor, but also prevent the damage of the laser to the exercise device.

When using the training device of the present invention to perform a laryngoscope simulated operation, the smoke in the throat enters the smoker through the insertion hole of the sleeve. The jack is located on the upper part of the sleeve, which can prevent the salt water cotton ball from blocking the jack, so as to ensure the smooth discharge of smoke.

(6) Actual laryngoscopy, by placing a saline cotton ball into the patient's throat at one time from the inside of the laryngoscope. When the laser device is a fiber laser, it will be inserted into the laryngoscope with the fiber laser. When using the training device of the present invention to perform a laryngoscope simulation operation, the laser device is also located in the laryngoscope, and the saline cotton ball is put into the sleeve from the side opening of the sleeve toward the laryngoscope. Compared with the actual laryngoscopy operation using the training device of the present invention, when the doctor needs to replace the animal's laryngeal tube and saline cotton ball due to repeated laryngoscopy simulation operation, it can be taken out from the opening of the sleeve and used. , and place a new saline cotton ball through the opening into the sleeve. It is not necessary to remove the fiber laser from the laryngoscope to replace the saline cotton ball, which not only meets the needs of doctors to practice repeated operations, but also reduces the complexity of laryngoscope simulation operations, which is convenient and quick.

When the laser device is not a fiber laser, but is coupled with a microscope, the laser light emitted by the laser device is injected into the laryngeal canal of the animal through the axial opening of the laryngoscope, which is convenient for the doctor to simulate the operation.

(7) When the laryngeal tube and laryngoscope are placed on the device, due to the same inclination of the two, the laryngoscope is just aligned with the laryngeal tube, which is convenient for doctors to place the laryngeal tube and laryngoscope without deliberately adjusting the two. Between the location, the operation is simple.
