Description

A single-port multi-channel surgical sheath for transumbilical single-port laparoscopic surgery

technical field

The invention relates to the technical field of laparoscopic instruments, in particular to a single-hole multi-channel surgical sheath for transumbilical single-hole laparoscopic surgery.

Background technique

Laparoscopic minimally invasive surgery is a milestone in the development of modern surgery. It has changed the concept of major surgery and large incisions in the past. Very complex major operations can also be completed through small surgical incisions. The biggest advantage of laparoscopic surgery is the quick recovery after surgery, which can achieve the purpose of rapid recovery. Because the wound is small, the postoperative pain is mild, and the patient can get used to getting out of bed earlier and rest better, and the patient will recover faster and be more willing to accept. Laparoscopic minimally invasive surgery brings a better surgical experience to patients, and also improves the fear of surgery for patients. In recent years, transumbilical single-port laparoscopic surgery has emerged at home and abroad. The natural scar of the umbilicus is used as an incision to establish a surgical channel. It has been confirmed that the surgical effect is consistent with conventional laparoscopic surgery, and there is no increase in the natural scar of the umbilicus. There are no extra incisions, so the cosmetic effect is remarkable, and it shows a good clinical application prospect.

The current surgical sheath still has the following problems:

Most of the existing channels are made of soft materials in order to facilitate penetration into the abdominal cavity, but such materials often have insufficient support for the abdominal wall and cannot make full use of the incision. Due to its original softness, the channel is narrow and the instrument is inconvenient to enter and exit;

Most surgical sheaths cannot flexibly adjust the length and angle of the sheath according to the specific conditions of the patient's operation. Furthermore, if several channels need to be temporarily closed in multi-channel surgery, there are also insufficient air tightness and interference with the use of other channels.

Based on these shortcomings of the existing surgical sheaths, the present invention designs a single-port multi-channel surgical sheath for transumbilical single-port laparoscopic surgery to solve the above problems.

A locking seal between the two; in a further scheme, a ring of sealing grooves 161 is set on the connecting end b16, a ring of anti-separation grooves 261 is set on the connecting end a26, and the sealing ring 40 is clamped on the outside of the anti-separation groove 261, As shown in FIG. 9 , the end of the sealing ring 40 is connected to the locking terminal 41, and the two locking terminals 41 are threadedly locked by the butterfly bolt 42 to seal the connection end a26 and the connection end b16. When the sheath body channel 10 is installed on the operating platform 20, the connecting end a26 at the bottom of the operating end 25 is clamped on the connecting end b16 on the upper part of the channel body 11, and the sealing ring 40 is hooped on the outside of the connecting end a26. The end a26 is soft, and the connecting end b16 is hard. When the sealing ring 40 reduces the radius through the butterfly bolt 42, the sealing ring 40 clamps the connecting end a26, so that the entire connecting end a26 is tightly closed on the connecting end b16 This allows for quick assembly and better air tightness.

In order to form an internal pneumoperitoneum and extract the water vapor in the abdominal cavity, the operation end 25 is provided with an air inlet end 23 and an air outlet end 24, which are connected to the gas circulation equipment to extract the internal water vapor and maintain the good visibility of the laparoscopic endoscope in the abdominal cavity.

Under normal circumstances, the surgical instruments need to perform multi-angle and multi-directional surgical operations when penetrating the surgical sheath. The column 30 is composed of a hard part 31, a deformation part 35 and a mounting part 36. The hard part 31 is used as the penetration start end of the surgical instrument, and one side of the rigid part 31 is integrally connected to the deformation part 35, and the deformation part 35 follows the use angle of the surgical instrument. The position of the hard part 31 can be fixed on the operation platform 20 when the deformed part 35 is in a retracted state; in order to maintain the airtightness of the surgical instrument penetration at the position of the hard part 31, the hard part 31 of the adjustment column 30 is adjusted. A valve 32 that can be kept airtight is arranged in the middle. The valve 32 is elastic and has a gap through which surgical instruments can pass through. Keeping the deformation closes the gap to form a sealing effect.

In order to solve the problem that it is difficult to adjust the existing surgical sheath to any angle, in the present invention, as shown in FIG. 10 and FIG. 11 , the deformation portion 35 is composed of a plurality of flexible corrugated bodies, and the The diameter gradually increases from top to bottom, and the ratio of diameter to length is 1:1.2:1.3. The pleated body can be expanded to both sides and closed inwardly, and the deformed part 35 will stretch and shrink accordingly. One side is retracted and the other side is unfolded. The entire adjusting column 30 has an angle that can be deflected to a convenient angle for the operation of the surgical instrument.

In order to ensure that the adjusting column 30 can be quickly installed on the operating platform 20, as a further solution, the bottom of the deformation portion 35 is connected to the mounting portion 36 with an inner groove, and the inner groove of the mounting portion 36 can be sealed and clamped on the through hole 22, In order to improve the sealing performance, an elastic gasket can be laid in the inner groove of the mounting portion 36 .

During the operation, according to the needs of the type of operation, the number of introduction channels to be used may be different, some of the adjustment columns 30 may not be used, and some adjustment columns 30 may need to be temporarily closed after use during the operation. , and when it is not needed, or when it needs to be temporarily closed during the operation, the adjustment column 30 will continue to maintain the original position, which will occupy the operation space and affect the operation. As an improved embodiment, the rigid part 31 is located on the valve.
