Novel biopsy forceps

Abstract

The present invention discloses novel biopsy forceps. A technical solution comprises the following main points: a protective sleeve for isolation is arranged outside a forcep frame assembly, the protective sleeve sleeves the forcep frame assembly and extends upward along a catheter, a first forcep knife is clamped in a first forcep seat, a second forcep knife is clamped in a second forcep seat, when a sliding sleeve pulls to a hand held ring, a pull wire moves along the sliding sleeve and drags a first connecting plate and a second connecting plate, the first forcep seat and the second forcep seat rotate oppositely, a first knife blade and a second knife blade cooperate to clamp biopsy tissues, and a first forcep groove and a second forcep groove present a sealed capsule shape capable of accommodating the biopsy tissues. The novel biopsy forceps have the following beneficial effects: the first knife blade and the second knife blade are cooperated to separate out the biopsy tissues, the knife blades are convenient and easy to use, the biopsy tissues are not liable to incomplete separation, and enlarge of cut wounds by dragging is avoided. A cavity body formed by closing of the forcep grooves accommodates and protects the separated biopsy tissues until the biopsy tissues are taken out, thereby avoiding errors of biopsy results caused by contamination.

Description

technical field [0001] The present invention relates to a kind of medical instrument, more particularly, it relates to a kind of novel biopsy forceps. Background technique [0002] Biopsy forceps are endoscopic accessories that directly manipulate the mucosal tissue of the body. When endoscopic examination needs to obtain pathological biopsy tissue, biopsy forceps is an indispensable tool. However, most of the conventional biopsy forceps do not avoid the exposure of the biopsy tissue, or directly tear off part of the tissue, and the biopsy forceps enter from the working channel of the endoscope. When the conventional biopsy tissue exits the working channel, it will be polluted by bacteria in the working channel, so When the biopsy tissue is taken out, other tissues of the human body or bacteria in the working channel are unavoidable pollution. Many people use biopsy tissue for examination and even research through biopsy tissue. In order to obtain accurate results, it is n...

Problems solved by technology

However, most of the conventional biopsy forceps do not avoid the exposure of the biopsy tissue, or directly tear off part of the tissue, and the biopsy forceps enter from the working channel of the endoscope. When the conventional biopsy tissue exits the working channel, it will be polluted by the bacteria in the working channel, so When taking out the biopsy tissue, other tissues of the human body or bacteria in the working channel are unavoidable contamination

Many people use biopsies for examination, and even conduct research through biopsies. In order to obtain accurate results, it is necessary to exclude various interferences, especially contamination of biopsies that may cause deviations in results

When using conventional biopsy forceps to obtain biopsy tissue, the obtained biopsy tissue is inevitably contaminated
