Problems solved by technology

However, when these technologies are actually implemented in the digestive tract biopsy process, they still face problems such as high cost, complex energy supply equipment, and insufficient positioning accuracy.
[0004] In addition, the existing digestive tract biopsy technology can only sample one part of the digestive tract at a time, which will prolong the diagnosis time of the disease and increase the pain of the patient

Abstract

The invention provides a multi-position liquid biopsy sampling device for the digestive tract. The multi-position liquid biopsy sampling device comprises a casing, wherein a plurality of sampling cavities are formed in the casing, the casing portion of each sampling cavity is provided with a through hole communicating the inside and the outside of the sampling cavity, the through holes of different sampling cavities are covered by targeting dissolving membranes dissolved at different targeting sites, expanding materials absorbing liquid to expand are further arranged in the sampling cavities,the expanding materials are adapted to the through holes in position, and the expanded materials absorb liquid to expand so as to close the through holes. The multi-position liquid biopsy sampling device for the digestive tract can accurately absorb the liquid of a plurality of targeted parts without an additional external power source, and can prevent the liquid of other parts from contaminatingthe sampled liquid.

Description

technical field [0001] The invention relates to the medical field, in particular to a multi-position liquid biopsy sampling device for the digestive tract. Background technique [0002] Gastrointestinal biopsy technique is of great significance for the diagnosis of gastrointestinal diseases. The traditional gastrointestinal biopsy technique uses surgical instruments such as tissue clips, electric knife, and puncture needle to obtain biopsy fluid or diseased tissue with the aid of an endoscope. Endoscopic mucosal dissection (EMR / ESD) and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) The level requirements are extremely high, and it is also accompanied by risks such as bleeding, artificial ulcers, tissue fibrosis, and mucosal perforation. [0003] With the development of micromachining technology, microelectromechanical technology (MEMS) represented by capsule endoscopy has opened up a new way for minimally invasive / comfortable biopsy sampling of the digestiv...
