Multi-channel soft abdominal wall working window

Abstract

The invention relates to medical apparatus and instruments, in particular to a multi-channel soft abdominal wall working window utilized in match with a laparoscope, the function thereof is equal to a laparoscope puncture cannula. The working window is a convergent of puncture cannulas, and is used for realizing single-hole laparoscope surgeries. The main body of the multi-channel soft abdominal wall working window is a column-shaped gas pocket or a dumbbell-shaped air pocket with two expanding ends; the column-shaped gas pocket is provided with at least more than two vertical work channels and gas tubes, when in use, the column-shaped gas pocket is put into an abdominal wall hole and is charged by the gas tubes; the charged column-shaped gas pocket is extruded with the abdominal wall to prevent the gas in the abdominal cavity from leaking outside; after the gas pocket is fully charged in the gas pocket, a work channel on the column-shaped gas pocket is extruded to be in a close state to prevent the gas in the abdominal cavity from leaking outside; the laparoscope and other apparatus and instruments are inserted to human bodies by the work channel to realize the function of channels; right now, under the pressure of the gas in the column-shaped gas pocket, the work channel clamps the laparoscope and other apparatus and instruments, which has the function of preventing the channel from leaking under the working state of the channel. The invention can realize one window body and a plurality of single work channels, and then further decrease the surgery incision number of a patient, therefore, the working window has the advantages of simplifying surgery operations, reducing surgery operators, realizing fixed and reliable connection, reducing the surgery incisions, providing possibility for single-hole laparoscope surgeries and the like.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a multi-channel soft abdominal wall working window used in conjunction with a laparoscope. Background technique: [0002] As we all know, due to the advantages of small wounds, short treatment time, and light pain for patients, laparoscopic surgery is more and more widely used. The laparoscopic working sleeve is placed in the human body as a channel for surgical instruments. The mirror and surgical instruments are sent into the human body through the working sleeve to realize diagnosis and surgical treatment. The existing laparoscopic working sleeve is in the shape of a straight tube, and without a fixing device, it is easy to come out of the human body during the operation, which delays the operation process. The second is that a working cannula has only one working channel, and can only enter one kind of instrument. If you want to enter multiple surgical instruments in the body at the same ...

[0002] As we all know, due to the advantages of small wounds, short treatment time, and light pain for patients, laparoscopic surgery is more and more widely used. The laparoscopic working sleeve is placed in the human body as a channel for surgical instruments. The mirror and surgical instruments are sent into the human body through the working cannula to realize diagnosis and surgical treatment. The existing laparoscopic working cannula is in the shape of a straight tube, and without fixing devices, it is easy to come out of the human body during the operation, which delays the operation process.

The second is that a working cannula has only one working channel, and can only enter one kind of instrument. If you want to enter multiple surgical instruments in the body at the same time, you have to build multiple working channels on the human body. Working window", and applied for the national invention patent and utility model patent respectively on 2007.
