Minimally invasive anal fistula treatment instrument

Abstract

The invention discloses a minimally invasive anal fistula treatment instrument. The treatment instrument comprises a shell, a clamping handle is arranged on the shell, and is of a cavity structure capable of being buckled, and the clamping handle is fixedly connected with the shell through a bolt. The treatment instrument also comprises an anastomosis mechanism arranged at the front end of the shell, a feeding mechanism, a transmission mechanism arranged in the shell and a safety mechanism arranged at the rear end of the shell. A rotating handle is fixedly installed at the tail end of the safety mechanism, and a degradable anal fistula inner opening plugging device is installed in the feeding mechanism. The treatment instrument is simple in structure and convenient to operate. The purpose of effectively closing the inner opening of anal fistula and the inner opening of other pathological fistulous tracts can be achieved, the operation burden of doctors is relieved, and the risk of secondary infection caused by incomplete closing of the inner opening of the fistulous tracts after an operation is reduced.

Description

technical field [0001] The invention relates to the technical field of minimally invasive medical devices, in particular to a minimally invasive treatment device for anal fistula. Background technique [0002] At present, the clinical treatment of anal fistula is mainly based on surgery, including anal fistula incision, anal fistula thread setting, sphincter preservation surgery, etc. Converted to restorative surgery. However, there are no good solutions and medical devices for the treatment of complex anal fistula, postoperative recurrence, slow healing and other clinical problems. Most of the existing tissue closures use materials that cannot be absorbed by the human body. When closing, stainless steel nails are used to anastomose the incision, or titanium alloy closing clips are used to close the internal opening of the anal fistula. The stainless steel nails need to be removed after a second operation. The closing clips will cause foreign body sensation when the patient...

Problems solved by technology

[0003] The purpose of the present invention is to provide a minimally invasive treatment device for anal fistula, aiming to improve the existing tissue closure devices that mostly use materials that cannot be absorbed by the human body, such as using stainless steel nails to anastomose the incision when closing the internal opening of anal fistula, or using titanium The alloy closure clip closes the internal opening of the anal fistula, and the stainless steel nail needs to be taken out in a second operation. The closure clip will cause a foreign body sensation when the patient defecates after the operation, and the whole operation needs to be performed, which increases the pain of the patient and the risk of the operation. traumatic issues
