Surgical abdominal cavity closure device

Abstract

The invention relates to the field of medical apparatuses and instruments, in particular to a surgical abdominal cavity closure device. The surgical abdominal cavity closure device comprises a seal bag and an abdominal wall fixing device. A first opening and a second opening are formed in the upper portion and the lower portion of the seal bag respectively, and a seal part is arranged in the first opening. The abdominal wall fixing device comprises a first fixing ring arranged above the abdominal wall, a second fixing ring arranged below the abdominal wall and a transparent film structure connected between the first fixing ring and the second fixing ring, and the distance between the first fixing ring and the second fixing ring is greater than the thickness of the abdominal wall. The upper portion of the abdominal wall fixing device extends into the seal bag from the second opening of the seal bag, the second opening is connected to the transparent film structure or the second fixing ring below the first fixing ring in a sealed mode, and a turnup distance for permitting outward turnup of the first fixing ring is reserved between the first fixing ring and the second opening. The surgical abdominal cavity closure device can achieve repeated opening and closing during operation and can also keep the gas tightness of the abdominal cavity.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an operation abdominal cavity closing device. Background technique [0002] With the improvement of medical level, endoscopic surgery is favored by more and more patients and medical staff due to its minimal invasiveness, accuracy and high efficiency. [0003] As we all know, in order to ensure the operation space and field of view of endoscopic surgery, it is necessary to inflate the patient's abdominal cavity to produce "pneumoperitoneum". During clinical operations, it is often encountered that the abdominal cavity needs to be opened and closed repeatedly. A surgical instrument that can be opened and closed repeatedly during surgery while maintaining the airtightness of the abdominal cavity. [0004] A patent number is 201410709787.9, named "Abdominal Cavity Opening and Closing Device". If it is difficult to adapt to the thickness of the abdominal wall of each individual, ...

Problems solved by technology

[0004] A patent number is 201410709787.9, named "Abdominal Cavity Opening and Closing Device". It is difficult to adapt to the thickness of the abdominal wall of each individual, and it is easy to cause air leakage or even detachment, so it is not suitable for large-scale industrial production and application

[0005] Another example is a patent No. 201620151621.4, named "Sandwich Type Abdominal Cavity Opening and Closing Device". This device adjusts the distance between the two fixed rings by moving the loop in the sandwich to solve the above-mentioned problem of differences in abdominal wall thickness between individuals. However, its sandwich structure is complicated, the operation is cumbersome, and it cannot be adjusted twice after being fixed, so it is still not conducive to large-scale industrial production applications.
