Superfine abdominal cavity optical biopsy forceps

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a pair of superfine abdominal cavity optical biopsy forceps. The instrument comprises a forceps head mechanism, a left handle, a right handle, a large catheter, a small catheter, a sliding block and a lock head mechanism, wherein the large catheter and the small catheter are fixed side by side, and the tong head mechanism in front of the small catheter is connected with the sliding block through a linkage module penetrating through the small catheter; the slider is movably connected with the right handle; the lock head mechanism is arranged at the tail end of the large guide pipe, and a distance fine adjustment module is arranged at the tail end of the large guide pipe. The distance fine adjustment module comprises a fixed end and a movable end; the movable end is movably connected to the fixed end in a sleeving mode, and the lock head mechanism is fixed to the movable end. According to the biopsy forceps, the extending length of a lens of endoscope equipment inserted into the large catheter can be finely adjusted through the distance fine adjustment module, and therefore stable self-defined adjustment of the observation view of an endoscope is achieved; therefore, by means of the instrument, medical staff can conveniently and comprehensively observe the tissue in the body of a patient during biopsy, biopsy efficiency can be improved, and remarkable substantive features are achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to ultra-fine optical biopsy forceps for abdominal cavity. Background technique [0002] Biopsy is the abbreviation of "biological tissue examination", also known as surgical pathological examination. The most important part of science, it can make a clear histopathological diagnosis for most of the cases submitted for inspection, and it is used as the final clinical diagnosis; with the development of modern medical technology, endoscopy is an extension of the doctor's eyes and hands, Has reached the "pervasive" state. Through endoscopy, the following diseases can be diagnosed: 1. Inflammation, ulcers, benign and malignant tumors that occur in the digestive tract (including esophagus, stomach, duodenum, small intestine and large intestine); 2. Liver, gallbladder, Benign and malignant lesions of pancreatic duct system; 3. Benign and malignant lesions of abdominal viscer...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the installation position of the endoscope of the biopsy forceps currently on the market is fixed, the observable field of view is extremely limited during the biopsy operation, and medical staff often cannot observe the things that need to be inspected through the endoscope when operating the biopsy forceps to process the internal tissue of the patient. The entire tissue area affects the efficiency of biopsy and the difficulty of equipment operation, providing ultra-fine abdominal optical biopsy forceps
