Background

With the progress of science and technology, the minimally invasive concept is continuously deepened into the heart, and the laparoscopic technology is rapidly developed in the treatment of rectal cancer. Various large hospitals in China can carry out the laparoscopic rectal cancer operation conventionally. During operation, after 5 operation holes are formed in the abdomen of a patient, the abdominal cavity of the patient is filled with carbon dioxide to maintain a certain pneumoperitoneum pressure (12-14mm mercury pressure), and the operation is performed in the closed abdominal cavity. After the laparoscopic operation procedure is completed, a small incision of about 5cm needs to be made in the abdomen of the patient to excise the tumor specimen and the anvil of the upper anastomat, and then the small incision is closed to perform subsequent laparoscopic anastomosis, reinforcement, flushing and other operation procedures. The conventional practice for closure of small incisions is: 1. temporary closure is performed with sutures. 2. A self-made slit inflator (see patent document CN 101129273A). 3. And (4) sleeving a latex glove on the silica gel incision protective ring for inflation. Practice 1 increases the amount of unnecessary work for the surgeon and wastes surgical time. The method 2 can be made by fully utilizing the existing materials in the operating room, has low cost (about 10 yuan), and simple structure, but requires several minutes for making, has simple making process, is really troublesome, has poor air tightness, and influences the operation of the operation. The silica gel incision protection ring prepared in the method 3 is high in cost (hundreds of yuan), and the latex gloves are poor in fitting performance with the silica gel incision protection ring.

The utility model discloses preferred manufacture process as follows: cutting a rubber tube with a set length, bending the rubber tube to form an annular structure, connecting the rubber tube at joints at two ends of the rubber tube through buckle type joints to obtain a lining ring, wherein the outer diameter of the lining ring is properly larger than the diameter of the medical plastic film (the soft sleeve has certain flexibility, and the lining ring can fully open the soft sleeve, so that the characteristic that the base of the incision inflation device is larger than the opening part is formed); intercepting a medical plastic film with a set length, penetrating one end of the medical plastic film from the center of the lining ring, and then turning over the end by taking the lining ring as an axis to obtain an inner-layer soft sleeve and an outer-layer soft sleeve, wherein the lining ring is wrapped in a connecting part of the inner-layer soft sleeve and the outer-layer soft sleeve, and the other ends of the inner-layer soft sleeve and the outer-layer soft sleeve are aligned; and (5) finishing the manufacturing. The mode of use of the present invention in surgery can be described in patent document CN 101129273A.

The utility model has the advantages that: when the lining ring is used, the lining ring can fully open the soft sleeve, so that the lining ring is prevented from sliding between the double-layer soft sleeve, and the double-layer film design is adopted, so that more folds can be formed compared with a single-layer film, the friction between the film and the abdominal wall is increased, the occurrence of air leakage is reduced, and the air tightness is enhanced; and the soft sleeve can be connected with the lining ring only in a one-time turnover mode, so that compared with a hot-press welding connection mode in patent document CN101129273A, the manufacturing difficulty is greatly reduced, and the manufacturing time can be saved.

The utility model discloses make full use of operating room current material makes, and is with low costs (about 10 yuan), simple structure, and the gas tightness is good, and the preparation time is about 20 seconds, and can act as incision protection device, avoids the emergence of incision infection.

the labels in the figure are: 1-lining ring, 2-inner layer soft sleeve, 3-outer layer soft sleeve, 4-buckle type joint, 5-abdominal cavity, 6-abdominal wall, 7-state after soft sleeve inflation, 8-small vessel forceps, and 9-fold formed between membrane and abdominal wall.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model comprises a lining ring 1 and a soft sleeve, wherein the lining ring 1 is of an annular structure, and the soft sleeve is of a hollow cylindrical structure; the soft sleeve is folded by taking the bushing ring 1 as an axis, so that the soft sleeve forms an inner soft sleeve 2 and an outer soft sleeve 3, and the bushing ring 1 is wrapped in the connecting part of the inner soft sleeve 2 and the outer soft sleeve 3.

For more conveniently utilizing the existing material to make, the utility model discloses it is preferred to implement through following mode: the lining ring 1 is an annular structure formed by bending the supporting rod, and the joints at the two ends of the supporting rod are connected through the buckle type joints 4. The supporting rod is a rubber tube, and the soft sleeve is a medical plastic film. The buckle type joint 4 is also an existing conventional part and is connected with a joint of a rubber pipe in a clamping manner. The outer diameter of the lining ring 1 is properly larger than the diameter of the soft sleeve (the inner diameter of the soft sleeve is equivalent to the outer diameter of the soft sleeve due to the thin film structure of the soft sleeve), and the lining ring 1 can fully open the soft sleeve due to certain flexibility of the soft sleeve, so that the characteristic that the base of the incision inflating device is larger than the opening is formed. The size difference between the outer diameter of the lining ring 1 and the diameter of the soft sleeve can be determined according to the material of the soft sleeve, and the size difference is feasible to be about 1cm for common medical plastic films.

The utility model discloses preferred manufacture process as follows: cutting a rubber tube with a set length, bending the rubber tube to form an annular structure, connecting the joints at the two ends of the rubber tube through buckle type joints 4 to obtain a lining ring 1, wherein the diameter of the lining ring 1 is properly larger than that of the medical plastic film; intercepting a medical plastic film with a set length, enabling one end of the medical plastic film to penetrate through the center of the lining ring 1, and then turning over the end by taking the lining ring 1 as an axis to obtain an inner-layer soft sleeve 2 and an outer-layer soft sleeve 3, wherein the lining ring 1 is wrapped in a connecting part of the inner-layer soft sleeve 1 and the outer-layer soft sleeve 3, and the other ends of the inner-layer soft sleeve 2 and the outer-layer soft sleeve 3 are aligned; and (5) finishing the manufacturing.

The mode of use of the present invention during surgery can be performed with reference to patent document CN101129273A, or can be performed with reference to the mode shown in fig. 3 of the present invention. When the method is implemented, firstly, the incision inflating device is manufactured according to the steps, then the position of the lining ring 1 is placed into the abdominal cavity 5 from the small incision of the abdominal wall 6, the lining ring 1 is tightly attached to the inner side surface of the abdominal wall 6, and the outer side surface of the outer-layer soft sleeve 3 is attached to the muscle of the incision of the abdominal wall 6; the double-layer soft sleeve can rebuild pneumoperitoneum after the opening end is sealed by the small vessel forceps 8, and the edge of the incision is not leaked gas any more after the lining ring 1 is pressed tightly with the inner side surface of the abdominal wall 6 by skillfully utilizing the pneumoperitoneum pressure. Referring to fig. 3, the present invention adopts a double-layer film design, which can form more folds (the fold formed between the film and the abdominal wall 6 is marked 9 in fig. 3) than a single-layer film, thereby increasing the friction between the film and the abdominal wall 6, reducing the occurrence of air leakage, and enhancing the air tightness.
