Abstract

The invention discloses a handheld multi-degree-of-freedom hemostatic cutter for an endoscope. The hemostatic cutter comprises an operating handle, a tool rod, an autorotation body and a cutter head. The hemostatic cutter is characterized in that: the upper and lower ends of the tool rod are provided with a deflecting wheel set respectively, the upper end of the deflecting wheel set at the upper end of the tool rod is connected with the operating handle through an autorotation seat, and the lower end of the deflecting wheel set at the lower end of the tool rod is connected with the autorotation body through the autorotation seat; the lower end of the autorotation body is connected with the telescopic cutter head; and the lower end of the cutter head is provided with at least two operating needles. The hemostatic cutter can assist a surgeon in finishing hemostatic cutting operation under a pure endoscope condition, saves complex suturing operation in the process of excising a tissue or an organ, and realizes less bleeding and even no bleeding so as to save the surgery time and ensure the surgery quality.

Description

technical field [0001] The invention relates to the technical field of surgical minimally invasive surgical instruments, and relates to a hand-held multi-degree-of-freedom hemostatic cutter for use under an endoscope. Background technique [0002] At present, incision, hemostasis, suturing, and knotting are the four basic operations of traditional surgery. Less or no bleeding during surgery is the highest pursuit of surgeons! In open surgery, relevant surgical tools have appeared, which can complete tissue cutting with little bleeding, such as electric knife, argon knife, ultrasonic knife, etc.; It is liberated from traditional surgical operations, reducing the labor intensity of doctors; and shortening the operation time, ensuring the quality of the operation, reducing complications, and saving clinical blood. [0003] Minimally invasive surgery represented by laparoscopy is known as one of the important contributions of medical science to human civilization in the 20th ce...
