AI Technical Summary
During distal gastric cancer NOSES surgery, the operator needs to retrogradely extend the manipulation forceps into the abdominal cavity and drag out of the specimen bag through the anus/vaginal cavity, which has the risk of tearing the specimen bag and may lead to tearing the vaginal or rectal wall, increasing the probability of the natural cavity tract being shed and transplanted by tumor cells.
A natural cavity incision protective sleeve for NOSES surgery is designed, including a protective sleeve body and an air leakage prevention mechanism. The protective sleeve body is composed of a pipe, an inner ring and an outer ring. The air leakage prevention mechanism is composed of three elastic valves to prevent incision tearing and tumor cells falling off.
By using an incision protective sleeve, the incision tear caused by improper force during the dragging of the specimen is effectively prevented, and the risk of tumor cell shedding and transplantation is reduced, ensuring the safety of sterile operation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of NOSES surgery, in particular to a natural cavity incision protective cover for NOSES surgery. Background Art
[0002] In today's era of minimally invasive and functional surgery, enhanced recovery after surgery is gaining popularity, and natural orifice specimen extraction surgery (NOSES) is also gaining traction. The hallmark of the NOSES procedure for total laparoscopic distal gastric cancer resection is the minimally invasive abdominal incision, enabling patients to resume normal life in the shortest possible time. This is highly consistent with the principles of the current biopsychosocial medical model.
[0003] The prior art has the following problems:
[0004] Currently, during NOSES surgery for distal gastric cancer, the conventional approach is to place the resected distal gastric cancer specimen into a specimen bag in the abdominal cavity and pull it out through the natural cavity (vagina / rectum). During this process, the operator needs to retrogradely insert the operating forceps into the abdominal cavity through the anus / vagina to pull out the specimen bag. During this process, there is a risk of tearing the specimen bag or tearing the vaginal or rectal wall due to the oversized specimen. This may also increase the probability of tumor cells being shed and implanted in the natural cavity that originally had no lesions. Utility Model Content
[0005] The purpose of the utility model is to solve the problem in the prior art that the operator retrogradely inserts the operating forceps into the abdominal cavity through the anus / vagina to pull out the specimen bag, and there is a risk of tearing the specimen bag during the process of pulling out the specimen, or tearing the vaginal wall or rectal wall during the process of pulling out the specimen due to the specimen being too large, and this may increase the probability of tumor cells being shed and implanted in the natural cavity that originally had no lesions. A natural cavity incision protective cover for NOSES surgery is proposed.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A natural cavity incision protective cover for NOSES surgery, comprising a protective cover body, wherein the protective cover body comprises a pipe, an inner ring and an outer ring, wherein the bottom of the outer ring is fixedly connected to the top of the pipe, and the top of the inner ring is fixedly connected to the bottom of the pipe;
[0008] The air leakage prevention mechanism is arranged in the pipeline to prevent air leakage.
[0009] In a possible design, the anti-leakage mechanism includes three elastic valves, and one side of the three elastic valves is fixedly connected to the inner walls of three sides of the pipeline respectively.
[0010] In a possible design, the length of the protective cover body is 20-25 cm.
[0011] In a possible design, the three elastic valves are conical in shape.
[0012] In a possible design, the inner ring is made of medical silicone.
[0013] In a possible design, the outer ring is in the shape of a figure 8.
[0014] In this application, the steps are:
[0015] Step 1: Fold the inner ring of the incision protection sleeve 1-2 times, grasp the inner ring with oval forceps and move it upward along the vaginal / rectal axis. Under the guidance of laparoscope, enter the abdominal cavity through the posterior vaginal fornix incision or the anterior rectal wall incision.
[0016] Step 2: Loosen the oval forceps and allow the inner ring to expand under its own elasticity;
[0017] Step 3: An operator holds the outer ring of the incision protection sleeve with both hands and gently pulls it outward until resistance is felt. The operator then observes the inner ring through the laparoscope to ensure that it is deployed and wrapped around the posterior vaginal fornix incision or the anterior rectal wall incision.
[0018] Step 4: The excessive length of the tube under the outer ring can be tightened by folding the outer ring, and finally the outer ring is fixed around the anus;
[0019] When the specimen is not being taken, the elastic valve is closed to prevent air leakage (by Figure 3 When taking the specimen, the elastic valve can be directly passed through by surgical instruments such as oval forceps, and adhere to the surface of the oval forceps with its own elastic force (by Figure 4 As shown), the protective cover body and elastic valve can effectively prevent the incision from being torn due to improper force during the specimen dragging process, and perform aseptic operation. At the same time, it can also prevent the tumor cells from falling off and implanting. Since the outer ring is in an 8-shape, it can be easily rolled up when used.
[0020] The beneficial effects of the present invention are:
[0021] In the present invention, the natural cavity incision protective cover for NOSES surgery has an air leakage prevention mechanism and three elastic valves. When the specimen is not being taken, the elastic valves are in a closed state to prevent air leakage.
[0022] In the utility model, the protective cover body and elastic valve can effectively prevent the incision from being torn due to improper force during the specimen dragging process, and perform aseptic operation. At the same time, it can also prevent the tumor cells from falling off and implanting. Since the outer ring is in an 8-shape, it can be easily rolled up during use. BRIEF DESCRIPTION OF THE DRAWINGS
