Problems solved by technology

[0003] The position determination of the capsule endoscope has the following difficulties: the line of sight is completely closed, making visual measurement unfeasible; surrounded by human tissues, the electromagnetic wave signal is strongly attenuated; its own volume is limited, making it impossible to install distributed receiving equipment; the market orientation is non-invasive and painless , making intrusive detection methods infeasible
At present, there is no product to design the position feedback of the capsule endoscope into the capsule endoscope system, let alone solve the problem of positioning the capsule endoscope in the electromagnetic field

Abstract

The invention provides a presumption method and device for a capsule endoscopy position. The method comprises the steps that magnetic field source parameters are called, a first magnetic field intensity of the capsule endoscopy position is received, based on the magnetic field source parameters and the first magnetic field intensity, the capsule endoscopy position is obtained, and the capsule endoscopy position is output. According to the presumption method, the magnetic field intensity of the periphery of the magnetic field source can be calculated through magnetic field source parameters, then through combining the magnetic field intensity of the capsule endoscopy position, the presumption of the capsule endoscopy position can be achieved, and the presumption of the capsule endoscopy position inside the human body is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a method and device for estimating the position of a capsule endoscope. Background technique [0002] The power of mainstream capsule endoscopes comes from external magnetic fields. The external magnetic field sources can be divided into two types: permanent magnetic sources and electromagnetic sources. Both types of magnetic sources have their own advantages. Controllable, high security. If you want to make the capsule endoscope precise and controllable during the control process, the electromagnetic source is undoubtedly a good choice. During the use of the electromagnetic source, due to the distribution characteristics of the magnetic field strength, it may be necessary to change the magnetic field strength of the electromagnetic source in real time with the distance between the capsule and the magnetic source for feedback adjustment to realize the grasping a...
