Problems solved by technology

[0003] Most of the existing biopsy extractors use the extraction cylinder to cut out the bone lesion tissue, and the bone lesion tissue stays in the inner cavity of the extraction cylinder and is taken out. The success rate of this type of biopsy extractor is relatively low for a single insertion into the bone to obtain a sample that meets the requirements

Abstract

The invention relates to the technical field of medical devices, in particular to an enclasping type biopsy extractor. The enclasping type biopsy extractor comprises a material taking assembly and an adjusting assembly. The material taking assembly comprises an inner tube and a handle, a through channel is formed in the handle, a connecting block is arranged in the channel, one end of the inner tube is fixedly connected with the connecting block, the other end of the inner tube is provided with material taking teeth, and the outer wall of the end, provided with the material taking teeth, of the inner tube is provided with a divergent section, a notch is formed in one end of the inner pipe provided with the taking teeth; the adjusting assembly comprises a sleeve, a sleeve connecting piece and a button, the sleeve connecting piece is installed in the channel, a sleeve installing hole, a connecting block containing hole and a button installing hole are sequentially formed in the sleeve connecting piece, the connecting end of the button is installed in the button installing hole in a limited mode, and the pressing end of the button abuts against the outer wall of the sleeve connecting piece, and a spring is arranged between the button and the connecting block. After bone focus tissue is cut, the bone focus tissue is held tightly and taken out smoothly, and the sampling success rate is extremely high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinging type biopsy extractor. Background technique [0002] Biopsy is the abbreviation of "biological tissue examination", also known as surgical pathological examination, which refers to the technique of cutting, clamping or puncturing the diseased tissue from the patient's body for pathological examination in response to the needs of diagnosis and treatment. The bone biopsy extractor is a tool used to remove tissue samples of bone lesions before the patient's planned operation, so as to make a definite diagnosis before the operation. [0003] Most of the existing biopsy extractors use the extraction cylinder to cut out the bone lesion tissue, and the bone lesion tissue stays in the inner cavity of the extraction cylinder and is taken out. The success rate of this type of biopsy extractor is relatively low for a single insertion into the bone to obtain a sample that ...
