Active colon micro-robot structure and working method thereof

Abstract

The invention discloses an active colon micro-robot structure and a working method thereof. The active colon micro-robot structure comprises an axial walking mechanism and two radial expansion mechanisms which are symmetrically and flexibly connected to the two ends of the axial walking mechanism; the axial walking mechanism comprises a walking casing, a walking battery, a walking motor, a motor driver, a screw nut mechanism A and a walking device, wherein the walking battery, the walking motor, the motor driver, the screw nut mechanism A and the walking device are arranged in the walking casing; each radial expansion mechanism comprises an expansion casing, an expansion battery, an expansion motor, a screw nut mechanism B and an expansion device, wherein the expansion battery, the expansion motor, the screw nut mechanism B and the expansion device are arranged in the expansion casing; the motor driver is electrically connected to the walking motor and the expansion motors. The axial walking mechanism achieves walking actions by adopting the walking motor for driving the walking device, and the radial expansion mechanisms achieve expansion actions by adopting the expansion motors for driving the expansion devices. The active colon micro-robot structure is simple, easy to control, low in cost, reliable in performance and capable of conveniently achieving actions such as moving forward, moving backward, stopping moving and making turns.

Description

technical field [0001] The invention relates to a colon micro-robot structure, in particular to an active colon micro-robot structure, which belongs to the technical field of medical devices. The invention also relates to the working method of the active colon micro-robot structure. Background technique [0002] The modern and fast pace of life has changed the traditional diet structure, coupled with the emergence of a series of problems such as environmental pollution and food safety, the incidence of digestive tract diseases in the world is increasing at a rate of 2% per year, while the incidence of digestive tract diseases in my country is increasing. The rate of digestive tract diseases is twice that of the world level. Gastrointestinal diseases are a common and frequently-occurring disease, and the incidence rate accounts for 10% to 20% of the world's total population. Polyp to colon cancer transformation. Colon cancer is a malignant lesion of the colon mucosal epitheli...
