Abstract

The invention discloses a medical self-supported type drive axial drive device which comprises a first movable part and a second movable part. The first movable part comprises a first sleeve, a coil and two circular-ring-shaped housings; the two housings are arranged between left and right ends of the first sleeve and is in interference fit to the first sleeve. The second movable part comprises two circular-ring-shaped pushing plates, a second sleeve and a limiting device; the two pushing plates are embedded into the middle of the first sleeve to form clearance fit with the first sleeve; and the second sleeve is arranged between the two pushing plates, is arranged at the radial outer side of the first sleeve, and forms clearance fit with the first sleeve. The device can realize single-direction axial motion or can realize yaw motion in the X-axis or Y-axis direction, has the advantages of being small in size and completely realizing self-supported type motion without an external magnetic field drive device.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical self-contained active axial drive device, which can be used as a movement mechanism of an endoscope or a microsurgical robot device. Background technique [0002] With the rapid development of medical science and technology, disease diagnosis, monitoring, sampling and clinical surgical treatment in vivo are becoming more and more minimally invasive and non-invasive. Endoscopic peristaltic robots are in increasing demand and higher requirements, especially for the volume, quality and function of this kind of robot. At present, commercial capsule robots, such as capsule endoscopes used to automatically take pictures of the digestive tract, mostly passively follow the peristalsis of the digestive system and cannot control their orientation, and incarceration and retention will occur in narrow and folded areas of the intestine. However, the motion devices using endoscopic ...
