Endoscopic capsule with device for assisting capsule advancement under edge friction condition

Abstract

A capsule for endoscopic examinations and a method for assisting the advancement of the capsule through organs are provided. In addition to a device for advancing the capsule through an organ under investigation, the capsule is also provided with a device for generating movements of the capsule to reduce the edge friction impeding the advancement of the capsule. The device for generating movements of the capsule is activated using electromagnetic radiation irradiated from outside to a receiving system of the capsule. The device generates a movement, which helps overcome inhibiting frictional forces.

Description

Endoscopic capsule with means to support delivery in case of edge friction technical field The present invention relates to a capsule for endoscopy and a method for supporting the transport of an endoscopic capsule through an organ. Background technique Classical endoscopy is a method widely used in medicine, both for the examination or diagnosis of patients and for the treatment or treatment of patients. In classic endoscopy, an endoscope or catheter is inserted through an opening in the patient's body, such as the mouth or anus, into a hollow organ (Hohorgan), such as the stomach or intestine, of the patient. However, classic endoscopes have the drawback of limited reach from the patient's body opening to the interior of his body or limited flexibility in order to follow curvatures or knots of hollow organs. For example, the small intestine of a patient, which is typically 7 to 8 meters long, cannot be completely reached, for example, by such a classic endoscope. En...

AI Technical Summary

Problems solved by technology

The rubbing of the capsule against the inner wall of the body cavity can then cause movement problems or motor blockages (Bewegungsblockaden)

This can be eliminated by a correspondingly high magnetic force acting on the capsule, however this is a very expensive solution
