Abstract

The invention provides a digestive tract liquid biopsy sampling device which comprises a casing and expansive materials. Through holes for communication of the inside and the outside of the casing areformed in the casing, and the through holes are covered with targeting dissolving membranes dissolved at targeting sites, the positions of the expansive materials adapt to the positions of the through holes, and the expansive materials absorb liquid to expand to block the through holes. The digestive tract liquid biopsy sampling device can accurately absorb the liquid at the targeted sites without an additional external power source, and can prevent the liquid of other parts from contaminating the sampled liquid.

Description

technical field [0001] The invention relates to the medical field, in particular to a digestive tract liquid biopsy sampling device. 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 digestive tract. However, when...
