Biopsy sampler for digestive tract tumor

Abstract

The invention provides a biopsy sampler for a digestive tract tumor, belonging to the technical field of medical instruments. The biopsy sampler for the digestive tract tumor comprises a placing plate, wherein the upper surface of the placing plate is provided with a display device and an inflation device, the lower surface of the placing plate is fixedly connected with an outer tube, the outer tube is internally provided with a connecting steel wire and a ventilation tube, the ventilation tube is internally provided with a cable conductor, one end of the connecting steel wire is fixedly connected with a pull ring, and the other end of the connecting steel wire is fixedly connected with a connecting base. Under the action of an inner support frame, an ellipsoidal air bag is greatly deformed at an elastic bag, so a sampling blade drives the fine hair of insoluble dietary fiber to move out of a sampling groove so as to clean dirt on the surface of the tumor, and then a soluble dietary fiber adhesion layer is dissolved, so the fine hair of the insoluble dietary fiber is separated and enters a digestive tract; after the ellipsoidal air bag is deflated, the elastic bag retracts, the sampling blade cuts the tumor and brings the tumor into the elastic bag, and then the tumor can be taken out after inflation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a biopsy sampler for digestive tract tumors. Background technique [0002] As an organ that directly accepts and digests food, the digestive tract of the human body is very harmful to dietary factors, and it also greatly increases the probability of developing digestive tract tumors. The digestive tract tumor sampler is a tool for biopsy sampling of digestive tract tumors. It uses a scraper to sample tumor tissues and is a commonly used sampling tool. [0003] The digestive tract tumor biopsy samplers currently on the market are complex in operation and structure due to the cooperation between the tumor removal structure and the scraper. The process only needs to clean up the vicinity of the tumor, which makes the structure of the existing digestive tract tumor biopsy sampler redundant, and the process of taking out the tumor sample is inconvenient.
