Abstract

A pair of manipulator-type endoscopic biopsy forceps relates to instruments and equipment for medical diagnosis, in particular to a pair of living tissue sampling forceps used for endoscopic examination and endoscopic surgery. The pair of manipulator-type endoscopic biopsy forceps comprises a forceps head, a control steel cable, a flexible outer pipe and an operating rod, as well as a manipulator consisting of both a swinging arm joint and a swinging arm, wherein the swinging arm joint is a slider crank mechanism consisting of a swinging arm base, a rotary base, a slider and a connecting rod; the swinging arm base, a swinging arm shaft and a connecting rod shaft constitute a crank of the slider crank mechanism; the rotary base is connected to a fixed base; the fixed base is connected to the operating rod through a flexible inner pipe; axial sliding of a swinging arm operation slip ring relative to the operating rod is conveyed to the slider of the slider crank mechanism through the flexible outer pipe; and the slider is connected to the swinging arm base through the connecting rod, drives the swinging arm base to rotate on the swinging arm shaft and also drives the swinging arm and the forceps head to swing around the swinging arm shaft. As the manipulator drives the forceps head to swing, and the forceps head rotates around the axis along with the rotary base, 360-degree all-view no-blind-area sampling around the axis of the fixed base can be realized.

Description

technical field [0001] The present invention relates to instruments and equipment for medical diagnosis, in particular to a biopsy forceps for endoscopy and surgery. Background technique [0002] In recent years, the incidence of gastrointestinal cancer has not declined with the development of medicine, but has increased due to various factors such as diet structure, environment, and genetics. Early diagnosis and early treatment of these diseases is the best way to avoid cancer metastasis and complications. For example, early gastric cancer can be cured with the help of effective surgical methods and radiotherapy and chemotherapy. By the late stage, its 5-year survival rate will be greatly reduced. According to the research results published by the American Cancer Society (ASC) in 2005, the five-year survival rate of gastric cancer has not improved significantly in the past 25 years. In addition, the incidence of colorectal cancer and Crohn's disease among gastrointestinal...
