Disposable bracing type multi-channel rectal anal pressure reducer

Abstract

The invention relates to the field of medical instruments, and discloses a disposable bracing type multi-channel rectal anal pressure reducer. The pressure reducer comprises five parts of two main body pipes A and B, a trapezoidal supporting frame, an inner sliding preventing air bag, and outer sliding preventing clamps, wherein multiple side holes are formed in the pipe walls of the two main bodypipes A and B, the trapezoidal supporting frame is provided with two sides A and B, and the two main body pipes A and B parallel adhere to the sides A and B of the trapezoidal supporting frame respectively to form a main body structure of the pressure reducer. The inner sliding preventing air bag adheres to the head side of the main body structure, and the outer sliding preventing clamps are arranged on the main body pipes A and B of the main body structure on the tail side of the air bag. After mid-low anastomosis of rectum is completed, the pressure reducer including the head side part of the inner sliding preventing air bag is embedded in, the air bag is inflated, the outer sliding preventing clamps are clamped by an anal opening, and the installation is completed. The pressure reducerhas the advantages that excellent pressure reducing and flow guiding effects can be achieved, not only can the occurrence of anastomotic leakage be prevented, but also the pressure reducer can be used for the expectant treatment after the anastomotic leakage occurs. After the use of the pressure reducer is completed, the inner sliding preventing air bag is deflated, and the pressure reducer can be taken out.

Description

technical field [0001] The invention belongs to a colorectal surgical instrument, and relates to a technology for preventing and treating middle and low rectal anastomotic leakage. Background technique [0002] In recent years, colorectal cancer has become a malignant tumor with high incidence worldwide. Among colorectal cancer patients in my country, the middle and lower rectum account for 60-70%. Therefore, a large number of patients receive resection and anastomosis of the middle and lower rectum every year. After middle and low rectal resection and anastomosis due to various reasons, the occurrence of anastomotic leakage has always been a difficult problem for surgeons. It has been reported in the literature that the incidence rate can reach 20%. The crux of the problem is that surgeons often cannot accurately predict in advance which surgical patients will have anastomotic leaks. After excluding the reason of the surgeon's operation technique, a common and important r...
