Sleeve structured medical in vivo minimally-invasive object-catching forceps

Abstract

The invention provides sleeve structured medical in vivo minimal-invasion object-catching forceps, comprising a binding clip component. The forceps are characterized in that the binding clip component mainly consists of a left binding clip (1), a right binding clip (2), a sleeve (3) and a control part (4) for controlling the open and close and the moving distance of the left binding clip (1) and the right binding clip (2), wherein the jaw parts of the left binding clip (1) and the right binding clip (2) extend out of the sleeve (3), while the tail parts of the left binding clip (1) and the right binding clip (2) are connected with each other through a connecting pin (5); the connecting pin (5) is connected with a drive inhaul cable one end of which is arranged in the sleeve (3) in a penetrating manner; outsides of the left binding clip (1) and the right binding clip (2) are provided with drive surfaces (3) which props against the port wall of the sleeve (3) and can automatically closed when driving the left binding clip (1) and the right binding clip (2) to contract inwards the sleeve (3); and the control part (4) is arranged on the sleeve (3). The forceps have the advantages of simple structure, convenient manufacture, low cost and high strength.

Description

technical field [0001] The present invention relates to a medical instrument, especially a kind of minimally invasive operation or inspection process used to clamp human tissue into biopsy, take out foreign matter that enters the human body or to help surgeons clamp human tissue to make it The positioned retrieval forceps is specifically a kind of sleeve structure minimally invasive retrieval forceps in the medical body. Background technique [0002] As we all know, minimally invasive surgery has developed rapidly in recent years, and it has the advantages of low surgical risk, small trauma, and fast recovery. In addition, endoscopy has been widely used in clinic as an auxiliary diagnostic method. In endoscopic examination, sampling forceps is an essential tool. When doctors or patients wish to conduct pathological examination on the lesion, it can enter the patient's body through the endoscopic forceps channel to clamp the tissue of the lesion for pathological examination....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of the existing four-connected biopsy forceps, which are difficult to manufacture, high in cost and low in strength, and to design a method that does not use a four-bar linkage mechanism to drive the left and right forceps heads, and at the same time, it is easy to manufacture and install, and its strength can be doubled. High-quality, low-cost sleeve-structure medical minimally invasive extraction forceps in vivo
