Abstract

The invention relates to the field of medical apparatuses and instruments, in particular to an intestinal tract biopsy medicine application capsule robot with an anchoring function. The robot comprises a capsule shell and a controller, a camera, a battery pack and a micro stepping motor which are fixedly arranged inside the shell, an actuator module achieving biopsy sampling and medicine application functions, a leg module achieving the capsule robot anchoring function, and a coupler and a transmission main shaft for transmitting power. The intestinal tract micro capsule robot is simple in structure, decoupling between the executor module and the leg module is achieved by means of a ratchet mechanism, one micro stepping motor can control two different functional modules at the same time, anchoring can be performed at the specific position inside the human intestinal tract, then, interference caused by natural wriggling of the intestinal tract is resisted, and the intestinal tract biopsy sampling success rate and medicine application accuracy are improved.

Description

technical field [0001] The patent of the present invention belongs to the field of medical devices, and in particular relates to an intestinal biopsy drug delivery capsule robot with an anchoring function. Background technique [0002] Biopsy refers to the technique of cutting, clamping or puncturing the diseased tissue from the patient's body for pathological examination in response to the needs of diagnosis and treatment. Current intestinal biopsies are mainly performed by endoscopic biopsy, but this technique causes significant intestinal trauma and discomfort. At the same time, precise drug application is an effective method in the treatment of intestinal diseases. However, due to the special and complex physiological environment and peristalsis of the intestinal tract, it is difficult to implement precise drug application at the patient's site with the current drug application methods. So many researchers are developing tiny swallowable capsule robots that can biopsy t...
