Gastrointestinal tumor biopsy sampling device

Abstract

The invention discloses a gastrointestinal tumor biopsy sampling device and belongs to the technical field of medical instrument equipment. The device comprises a lifting assembly, a rotating assembly, a sampling assembly, an expansion assembly, a dirt sucking assembly and a moving assembly, wherein the moving assembly is vertically arranged; the rotating assembly is arranged on the moving assembly and is rotationally connected with the moving assembly; the lifting assembly is arranged at the top of the rotating assembly; the sampling assembly is arranged at the lifting end of the lifting assembly; the sampling assembly comprises a sliding part and two sampling parts; the lifting part is arranged at the lifting end of the lifting assembly; the two sampling parts are symmetrically arrangedat the moving end of the sliding part; the expansion assembly is arranged at the lifting end of the lifting assembly; and the dirt sucking assembly is arranged at the lifting end of the lifting assembly and is positioned at the other end of the sampling assembly. By adopting the device, scraping and sampling operation on a tumor part of a patient is implemented in all direction in multiple anglesthrough swinging of a sampling blade, so that samples of different parts of a tumor of the patient can be obtained.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a biopsy sampling device for digestive tract tumors. Background technique [0002] The digestive system consists of two parts, the alimentary canal and the digestive glands. Digestive canal: including oral cavity, pharynx, esophagus, stomach, small intestine (duodenum, jejunum, ileum) and large intestine (cecum, appendix, colon, rectum, anal canal). Clinically, the section from the oral cavity to the duodenum is often called the upper gastrointestinal tract, and the part below the jejunum is called the lower gastrointestinal tract. There are two types of digestive glands: small digestive glands and large digestive glands. The small digestive glands are scattered in the walls of the digestive canal. The large digestive glands have three pairs of salivary glands (parotid glands, submandibular glands, and sublingual glands), liver and pancreas. The digestive system is one ...
