Abstract

The invention provides a capsule endoscope system having an ultrasonic positioning function and belongs to the technical field of medical instrument auxiliary devices. The capsule endoscope system solves the problem that the complex degree of a positioning system is increased in the prior art. The capsule endoscope system having the ultrasonic positioning function comprises a capsule endoscope and an external control unit. An MCU control circuit, a miniature ultrasonic transmission module and a radio frequency wireless transmission module are arranged in the capsule endoscope, wherein the miniature ultrasonic transmission module and the radio frequency wireless transmission module are connected with the MCU control circuit. The external control unit comprises a microcontroller, a radio frequency receiving module and an ultrasonic receiving and processing unit, wherein the radio frequency receiving module and the ultrasonic receiving and processing unit are connected with the microcontroller, an audio and video signal processing module is connected between the microprocessor and the radio frequency wireless receiving module, and the microcontroller can obtain the accurate position of the capsule endoscope in the body of a patient in real time through a sound velocity and temperature compensation formula and a spatial orientation algorithm. The capsule endoscope system can obtain the accurate position of the capsule endoscope in the body of the patient in real time and is high in positioning accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical equipment auxiliary equipment, and relates to a capsule endoscope system with an ultrasonic positioning function, in particular to a medical capsule endoscope system suitable for the inspection, diagnosis and positioning functions of digestive tract diseases. Background technique [0002] Capsule endoscope is also called medical wireless endoscope. The working mechanism is: when the capsule endoscope is swallowed by the patient, with the help of the peristalsis of the human digestive tract, the image is recorded along the digestive tract at a rate of several frames per second, and the image data is sent to the external data recorder or can be wirelessly transmitted. Wearing the device, the whole process lasts for 8-15 hours, and records about 50,000-90,000 pictures. Doctors with clinical experience check all the pictures and analyze digestive tract diseases with the help of PC computer or image di...
