Biopsy sampler for body surface tumors

Abstract

The invention discloses a body surface tumor biopsy sampler, which comprises a holding sleeve, a pressing handle, a stable ring and a sampling head. A pair of vertical connecting rods are installed on the outer surface of the holding sleeve, and the connecting rods The bottom is jointly connected with a horizontal stable ring, the inside of the holding sleeve is provided with a vertically penetrating sliding channel, the middle of the pressing handle is symmetrically fixed with lower pressing blocks on both sides, and the holding sleeve passes through the sliding channel It is sleeved outside the pressing handle, and the side of the lower pressing block is in contact with the inner wall of the sliding channel. The pressing handle is covered with a spring. The upper surface of the platform extending from the inner lower part of the pipe to the central axis is abutted and connected. The body surface tumor biopsy sampler has a simple structure, strong integrity, can be operated with one hand, reduces the damage caused by human factors in the sampling process, is more stable, is simple and convenient to replace the sampling head, and has popularization value.

Description

technical field [0001] The invention belongs to the technical field of tissue sampling devices, in particular to a body surface tumor biopsy sampler. 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. Biopsy is the main way to obtain pathological diagnosis results. [0003] In recent years, with the development of tumor molecular biology, the treatment of solid tumors has increasingly emphasized individualized comprehensive treatm...

Problems solved by technology

Biopsy includes two forms of puncture cutting and open biopsy. The current biopsy methods used in clinical practice at home and abroad are not ideal.

The existing sampler for puncture and cutting biopsy can only cut the living tissue when piercing, and when the sample body is to be removed, the surgeon needs to cut the sample body with a knife, which is very inconvenient, and in the sampling process, it is easy to exist Human factors such as hand shaking make the sampling process unstable and increase patient pain
