Minimally invasive puncture sampling device for pathological examination

Abstract

The invention relates to the technical field of pathological diagnosis, and discloses a minimally invasive puncture sampling device for pathological examination, which comprises a needle core for puncturing and sampling a minimally invasive part, a handheld block arranged on the needle core, a protective sleeve assembly and a removing assembly, the protective sleeve assembly comprises a needle sleeve sleeving the outer side of the needle core and a housing sleeving the outer side of the handheld block, one end of the housing is open, and the other end of the housing is connected with the needle sleeve and provided with a needle hole which is communicated with the needle sleeve and allows the needle core to penetrate into the needle sleeve. And two opposite hook parts are elastically arranged on the end wall of the open end of the housing. The section of the handheld block is of a circular structure, and the peripheral side of the handheld block is provided with a groove corresponding to the hook part. And when the housing is sleeved on the handheld block, the two hook parts are clamped and fixed in the groove. The releasing assembly is used for releasing clamping and fixing of the hook part in the groove. The protective sleeve assembly is additionally arranged on the outer side of the needle core and the outer side of the handheld portion, the needle core is effectively protected and prevented from being damaged by external impact, and the protective sleeve assembly is removed so that the needle sleeve and the housing can be disassembled after being installed.

Description

technical field [0001] The invention relates to the technical field of pathological diagnosis, in particular to a minimally invasive puncture sampling device for pathological examination. Background technique [0002] At present, surgical treatment of lesions in the human cavity has changed from traditional open surgery to minimally invasive surgery. It is necessary to use biopsy to puncture and sample the minimally invasive area, and then perform pathological examination and analysis on the sampled tissue. [0003] The puncture sampling biopsy needle used for pathological examination in the prior art is mainly composed of a needle core for puncturing and sampling minimally invasive parts and a hand-held block detachably arranged at one end of the needle core for hand-held operation by medical staff. The core lacks effective protection before it is used, and is easily bent and damaged by external impact, which affects the progress of minimally invasive surgery. Contents o...
