Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing by non-limiting embodiment:

[0031] As shown in the accompanying drawings, an active micro-robot structure for the colon includes an axial traveling mechanism 2, two radial expansion mechanisms 1 and 3 that are symmetrically and flexibly connected to the head and tail ends of the axial traveling mechanism 2, and the two The two radial expansion mechanisms are arranged oppositely. In this embodiment, preferably, the axial running mechanism 2 is connected with the two radial expansion mechanisms 1 and 3 through a bellows 4 . The axial traveling mechanism 2 includes a traveling housing 2-14, a traveling battery 2-1, a traveling motor 2-2, a motor driver 2-8, and a screw nut mechanism A arranged in the traveling housing 2-14. , Walking device. The traveling motor 2-2 is fixedly installed in the traveling housing 2-14 by the traveling motor baffle plate 2-3 arranged on its front...

Abstract

The invention discloses an active colon micro-robot structure and a working method thereof. The active micro-robot structure of the colon includes an axial walking mechanism and two radial expansion mechanisms that are symmetrically and flexibly connected to both ends of the axial walking mechanism. The axial walking mechanism includes a walking shell, a walking battery, a walking motor, Motor driver, lead screw and nut mechanism A, walking device, radial expansion mechanism includes expansion housing, expansion battery arranged in the expansion housing, expansion motor, lead screw and nut mechanism B, expansion device, the motor driver and the walking The motor is electrically connected with the expansion motor. The axial traveling mechanism realizes the walking action by driving the traveling device through the traveling motor, and the radial expansion mechanism realizes the expansion action through the expansion motor driving the expansion device. The invention has the advantages of simple structure, simple control, low cost and reliable performance, and can conveniently realize actions such as advancing, retreating, staying, and turning.

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...
