Abstract

The invention discloses a pawl resetting type capsule endoscopy robot parking and pose adjusting device and method and relates to an endoscope micro capsule robot. The pawl resetting type capsule endoscopy robot parking and pose adjusting device comprises a capsule casing, a driving motor, a screw nut mechanism, a guiding mechanism and a foldable mechanism; The driving motor drives a screw to rotate to drive a nut to move along the guiding rod and enable the foldable mechanism to collect and release to achieve robot parking and positioning; or the screw drives the nut to rotate relative to the foldable mechanism which is folded and positioned inside an intestinal tract to drive a capsule function cabin to rotate surrounding an axis and accordingly pose of the robot is adjusted. The capsule casing and an elastic skin which covers the foldable mechanism defines the integral capsule endoscopy robot to be a seal chamber. The pawl resetting type capsule endoscopy robot parking and pose adjusting device has the advantages of enabling the structure to be simple through an under-actuated mode; solving the problems that the capsule endoscopy robot is large in size, swallow is not easy, and wriggle inside the intestinal tract is difficult; achieving omnibearing diagnosis and treat of a gastrointestinal tract of a patient.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pawl reset type capsule endoscopic robot parking and posture adjustment device and method. Background technique [0002] Capsule endoscope is a kind of endoscope made in the shape of capsule, which is a medical instrument used to check the health status of human gastrointestinal tract. The capsule endoscopic robot uses active and passive drive control methods to move in the human gastrointestinal tract, spy on the health status of the human gastrointestinal and esophagus, and then help doctors diagnose or even treat patients. [0003] The development of medical endoscope can be divided into two stages according to the change of its realization method: cable endoscope and wireless capsule endoscope. [0004] The traditional cable-type endoscope has undergone continuous changes and improvements since its inception, and has now become an important instrument for medical examin...
