Tumor biopsy sampling device used for clinical medicine

Abstract

The invention discloses a tumor biopsy sampling device used for clinical medicine. The device comprises a bottom cylinder which is vertically through, wherein a top base is movably connected with thetop of the bottom cylinder, butt straps are fixedly connected with both sides of the top base, a baseboard is fixedly connected with the inner wall, close to the bottom of the bottom cylinder, on thebottom cylinder, a space in a cavity of the bottom cylinder is divided into a sliding cavity and an accommodating cavity by the baseboard from top to bottom, a sliding hole is formed in the middle portion of the baseboard, a sliding rod is arranged on the inner wall of the sliding hole in a sliding mode, the bottom end of the sliding rod is movably connected with a sampling part after penetratingthrough the accommodating cavity, the top end of the sliding rod is fixedly connected with a press board after penetrating through the sliding cavity, the outer wall of the press board is connected with the inner wall of the sliding cavity in a sliding mode, a reset spring abuts against the opposite surfaces of the press board and the baseboard, a pressing rod is fixedly connected with the top ofthe press board, and the pressing rod is fixedly connected with a pressing board after penetrating through the top base. The tumor biopsy sampling device used for clinical medicine has the advantagesof being simple in structure and convenient to operate, and the problems raised in the background art are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tumor biopsy sampling device for clinical use in medicine. Background technique [0002] Early detection, correct diagnosis and timely treatment have an important impact on the prognosis of tumors. In recent years, with the continuous improvement of inspection methods and methods, the accuracy of tumor diagnosis has gradually increased, but a large part of tumors still do not have typical imaging features, so there are problems in the diagnosis of simple imaging techniques. Accurate diagnosis requires a combination of clinical, imaging, and pathological conditions, among which pathological diagnosis plays a key role in the selection of treatment options. Due to the heterogeneity of the tumor, multiple biopsy sampling of the diseased tissue is required to avoid misdiagnosis. Clinically, when taking tumor biopsy samples from patients, most of them directly use syringes ...

Problems solved by technology

[0004] However, this tumor biopsy sampler has the following disadvantages: (1) Although the sampling slot on the puncture head takes samples, the sample is not easily retained in the sampling slot; (2) The puncture head is always exposed to the outside no matter before or after sampling , contaminated by impurities such as dust, which greatly interferes with the accuracy of biopsy results
