Abstract

The invention discloses a support device for a postoperative anastomotic fistula. The support device comprises a sleeve with a cavity inside, a support pipe slidably connected in the sleeve and a push-pull pipe connected at the end part of the sleeve, wherein the support pipe comprises a base layer, a supporting and protecting layer matched with the periphery of the base layer, a plurality of rowsof reducing supporting and protecting components which are connected between the base layer and the supporting and protecting layer and are circumferentially arranged, and a sealing stretching ring which is arranged between an end part of the base layer and an end part of the supporting and protecting layer and is used for controlling reducing of the reducing supporting and protecting components;and the sleeve is slidably connected on the outer wall of the supporting and protecting layer. The support device has a simple structure, is convenient and reliable to use, and provides reliable guarantee.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bracket device for postoperative anastomotic leakage. Background technique [0002] Anastomotic leakage is the most common serious complication after surgery for gastric cancer and rectal cancer, and it is also the main cause of death. avoid. Once anastomotic leakage occurs, depending on the degree, some patients can recover after conservative treatment, while some patients need a second operation. In this case, if an anastomotic leak occurs, a stent is placed through the mouth or rectum by interventional means to prevent intestinal contents from passing through the fistula, keep the fistula clean, and prevent intestinal contents from entering the abdominal cavity and cause abdominal infection, which will eventually promote anastomosis Healing of fistula. However, the existing stent is inconvenient to operate. During the process, the stent is prone to loosening a...
