Abstract
A capsule-type anchored biopsy robot driven by an external magnetic field relates to a biopsy robot, which is designed to solve the problem that the existing capsule robots have weak active movement ability and cannot stay in the gastrointestinal tract for a long time. The anchoring module of the present invention is used to control the biopsy robot to stay in the gastrointestinal tract; the camera module is used to collect images of in vivo tissues; the biopsy module is used to pick up in vivo tissues; the driving module is arranged between the anchoring module and the biopsy module, and when the driving module is in the driving mode, the driving module is excited by an external driving magnet to realize the active movement, pitch angle and deflection angle of the biopsy robot for adjustment; when the driving module is in the working mode, the biopsy module is driven to enter the working mode; or the driving module is excited by an external driving magnet to swing toward the anchoring module, so as to drive the anchoring module to enter the working mode. The beneficial effect is that the anchoring module can be anchored and stay in the intestine, which is convenient for biopsy.
