The invention discloses a micro magnetic positioning device and a micro magnetic positioning method for positioning a micro in-vivo diagnosis and treatment device. The micro magnetic positioning device comprises a magnetic field generator, a magnetic sensor module and a data processing module, wherein the magnetic field generator is arranged in the micro in-vivo diagnosis and treatment device; the magnetic sensor module comprises three triaxial magnetic sensors; first and second triaxial magnetic sensors are arranged at different positions of the abdomen of a human body; a third triaxial magnetic sensor is arranged at the other position and used for measuring the magnetic field intensity of the position; and the data processing module is connected with the magnetic sensor module and used for calculating the intensity of magnetic fields generated by the magnetic field generator at the positions of the first and second triaxial magnetic sensors according to a measuring result and calculating the current position of the micro in-vivo diagnosis and treatment device by using a magnetic dipole model. Compared with the conventional positioning method, the micro magnetic positioning method has the advantages that: the micro in-vivo diagnosis and treatment device can be simply, quickly and accurately positioned, the human body is not harmed in the positioning process, the normal work of a detected person is not influenced, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of in vivo diagnosis and treatment, in particular to a miniature magnetic positioning device and method for positioning a miniature in vivo diagnosis and treatment device. Background technique [0002] With the development of microelectronics technology, MEMS (micro electromechanical system) technology, robotics technology, wireless communication and other technologies, miniature in vivo diagnosis and treatment devices have become the research hotspot and development direction of modern medical devices. The miniature in vivo diagnosis and treatment device can enter the human digestive tract, detect physiological parameters of the digestive tract, identify diseased tissues, and actively administer medicine or perform surgery. [0003] In medical applications, doctors often need to know the exact position of these miniature in vivo diagnosis and treatment devices in the patient's body when using them. one of ...
