Problems solved by technology

[0002] At present, the lenses of capsule endoscopes are basically fixed, and the field of view is very limited. At the same time, the rugged and changeable intestinal tract, peristalsis and intestinal fluid will also lead to a limited field of view of the lens, which cannot be accurately positioned, and it is difficult to accurately capture the lesion.

Abstract

The invention discloses multi-degree-of-freedom ultrasonic motor direct-drive capsule endoscope and an operation method thereof, which includes a camera, a capsule head, a head swing system, flexiblecovering material and a capsule body. The head swing system includes a base fixing frame, a first flexible base, a first stator, a first piezoelectric ceramic, a ball rotor, a second flexible base, asecond stator, a second piezoelectric ceramic, a third flexible base, a third stator and a third piezoelectric ceramic. When different stators are respectively powered on, the capsule heads can swingaround different stator axis. The compact parallel structure form can realize the swing of lens of the capsule endoscope, enlarge the angle of the lens, and realize accurate positioning of the lens.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive diagnosis and treatment robots, and relates to a capsule endoscope directly driven by a multi-degree-of-freedom ultrasonic motor and an operating method thereof, in particular, to a multi-degree-of-freedom ultrasonic motor direct-driven capsule endoscope based on a spherical contact pair A capsule endoscope system with a swingable lens and an operating method thereof. Background technique [0002] At present, the lenses of capsule endoscopes are basically fixed, and the field of view is very limited. At the same time, the rugged and changeable intestinal tract, peristalsis and intestinal fluid will also lead to a limited field of view of the lens, which cannot be accurately positioned, and it is difficult to accurately capture the lesion. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, to provide a capsule e...
