The invention discloses a micro positioning device applied to a micro in-vivo diagnosis and treatment device and a positioning method. The method comprises the following steps that: a first acceleration sensor is arranged in the micro in-vivo diagnosis and treatment device; after the micro in-vivo diagnosis and treatment device enters a human body, the first acceleration sensor performs acceleration sampling according to preset sampling frequency and sends the acquired acceleration data signal to an in-vitro data processing module in a wireless mode; and the data processing module calculates the motion path of the micro in-vivo diagnosis and treatment device according to acceleration variable linear motion based on the received acceleration data signal in vitro. The micro positioning device is suitable for more simply, quickly and accurately positioning the micro in-vivo diagnosis and treatment device in the human body when the human boy is still and moves, has the advantages of low power consumption, small volume and light weight, is harmless to the human body in the positioning process and does not influence the normal work of a detected person, 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 micro-acceleration positioning device and a positioning method for the micro-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 ...
