Problems solved by technology

[0003] 1) Because the end is relatively soft, it takes a lot of time to clamp the lesion and cut the tissue away from the front end of the endoscope, and it is not easy to capture the lesion tissue;
[0004] 2) When the lesion is in the folds of the digestive tract, it is difficult for the sampler to sample or inspect

Abstract

The invention relates to a sampling device for a gastrointestinal endoscope. The sampling device comprises a control device, a bendable sleeve and a driving wire, wherein one end of the bendable sleeve is connected with the control device; the driving wire is movably arranged on the inner side of the bendable sleeve, and one end of the driving wire is in driving connection with the control device. The sampling device for the gastrointestinal endoscope further comprises a fixed seat and a sampling ring; the fixed seat is fixedly connected with the other end of the bendable sleeve, and the fixed seat is provided with a fixed part; and the sampling ring is fixedly connected with the tail end of the driving wire, the sampling ring is arranged at one end of the fixed seat in a bending manner, and one end of the sampling ring is fixedly connected with the fixed part. The sampling ring which is unfolded in the shape of a butterfly is telescopically and movably arranged on the fixed seat, so that the whole sampling ring can directly face a lesion in the use process, the lesion part can be quickly searched, and the lesion part can be quickly extracted for sampling.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sampling device for gastroenteroscopes. Background technique [0002] If lesions are found during gastrointestinal endoscopy, it is necessary to use a sampler to take samples for pathological examination to clarify the nature of the lesions. At present, the commonly used gastroenteroscope sampler, the front end is to open the jaws by pushing the handle and the handle slider behind the handle to perform multiple sampling of the gastrointestinal tract tissue. This sampler has the following technical problems: [0003] 1) Because the end is relatively soft, it takes a lot of time to clamp the lesion and cut the tissue away from the front end of the endoscope, and it is not easy to capture the lesion tissue; [0004] 2) When the lesion is in the folds of the digestive tract, it is difficult for the sampler to sample or inspect. Contents of the invention [0005] In orde...
