Tumor sampling device

Abstract

The invention belongs to the technical field of medical machinery, and particularly relates to a tumor sampling device. The tumor sampling device comprises a sampling needle head and a sampling knifelocated in the sampling needle head, wherein sampling holes are formed in the sampling needle head; a placement cavity is formed in the sampling needle head; the sampling knife is mounted in the placement cavity and mounted at the left end of a first pull rod; a first pull plate is mounted at the right end of the first pull rod; the sampling needle head is mounted on the left side of an injector;a piston is mounted in a cavity in the injector and mounted at the left end of a second pull rod; a second pull plate is mounted at the right end of the second pull rod; and a handheld rod is mountedon the outer wall of the injector. A plurality of samples can be taken once conveniently by the aid of the multiple sampling holes formed in the sampling needle head, the representativeness of the samples is greatly improved, the samples taken in the sampling needle head are taken out by the sampling knife, the samples in the sampling needle head are taken out simply and conveniently, and the speed and the efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a tumor sampling device. Background technique [0002] In recent decades, although modern medicine has achieved full development and obvious progress, tumors are still an important problem that plagues today's medicine. How to overcome tumors has always been a key research topic in the medical field. It is well known that tumor tissue differs from the normal tissue from which it originates in varying degrees in terms of cell morphology and tissue structure, and this difference is called atypia. Specifically, atypia is the morphological manifestation of abnormal tumor differentiation, and small atypia indicates high degree of differentiation; large atypia indicates low degree of differentiation. In actual clinical medicine, distinguishing the size of atypia is the main histological basis for diagnosing tumors and determining whether they are benign or malignan...

AI Technical Summary

Problems solved by technology

[0004] 1. The syringe needle is smooth and the needle cavity is narrow, and it is not easy to take out and separate the tumor tissue after entering the needle cavity; it brings inconvenience to the doctor's work;

[0005] 2. Only one sample can be taken at a time, and the representativeness of the sample is poor
