Abstract

The invention discloses a capsule endoscopy having an accurate positioning function. The capsule endoscopy comprises a capsule shell, a pH sensor, a photographic device, a control device and a positioning device; the positioning device comprises micro legs, rubber wheels, pressure sensors, springs and a motor, wherein the micro legs are arranged on the outer sides of the capsule shell; one end of each of the micro legs is connected to the corresponding rubber wheel; revolution measuring devices are arranged on the rubber wheels; the springs and the motors are connected to the other ends of the micro legs; under the control of the springs, the micro legs are expanded; the micro legs, driven by the motor, contract; and the pressure sensors are additionally arranged on the springs. According to the capsule endoscopy having the accurate positioning function provided by the invention, through the rotation of the rubber wheels and by converting the revolution into a distance, accurate positioning inside the digestive tract of a human body is achieved; and meanwhile, by virtue of the micro legs and the rubber wheels connected to the micro legs, any instable and non-forward movement is minimized, so that the photographic device in the capsule can record stable images or videos.

Description

technical field [0001] The present invention relates to the technical field of medical instruments, in particular to a capsule endoscope with precise positioning function. Background technique [0002] Capsule endoscopy is used to take images or videos of the inner wall of the human digestive tract while moving in the human digestive tract, and transmit them wirelessly to an external signal receiving device. Doctors then screen and diagnose based on these images or videos, which requires correct It can accurately identify where these images or videos are in the digestive tract. [0003] At present, there are mainly two methods to obtain the position information of the capsule endoscope: (1) a method based on magnetic field strength; (2) a method based on electromagnetic waves. The method based on magnetic field strength generally installs a permanent magnet in the capsule endoscope, and configures a magnetic sensor array on the abdomen outside the examiner’s body. When the ...
