Sampling shell and digestive system department biopsy sampler comprising same

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a sampling shell and a gastroenterology biopsy sampler comprising the same, the sampling shell comprises a main body, the lower end of the main body is provided with a piercing part, and the outer side of the lower end of the main body is provided with a shell body used for connecting the main body with the piercing part; a sampling groove is formed in the outer side, close to the lower end, of the piercing part. A pressing plate is pulled outwards to take out an extrusion plate shaft, so that extrusion limiting on an inner ring sleeve can be relieved, at the moment, a penetrating part is pulled to enable a limiting strip to be separated from the interior of a clamping groove to complete dismounting of the penetrating part, operation is easy, use is convenient, meanwhile, mounting and dismounting of the penetrating part can be rapidly completed, a sample body is taken out, and the working efficiency is improved; the rod body in the main body is pushed to drive the limiting seat to move downwards to compress the telescopic rod, at the moment, the pull rope can drive the sealing ring to move upwards to seal the sampling groove, the operation is simple, cross infection caused by sample body sliding can be effectively avoided, and the influence of sample body reduction on examination use is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a sampling shell and a gastroenterology biopsy sampler containing it. Background technique [0002] Biopsy is referred to as biopsy, also known as surgical pathological examination, referred to as external examination, which refers to the technology of cutting, clamping or puncturing diseased tissues from the patient's body for pathological examination in response to the needs of diagnosis and treatment, so it is often used A sampling housing and a gastroenterology biopsy sampler containing the same. [0003] In the original technology, it is not convenient to take out the sample body from the inside of the sampler after sampling, and the work efficiency is low; and after sampling, the sample body is easy to slip out and cause infection, and the sample body is reduced, which is not convenient for later inspection and use; and It is easy to shake during use, c...
