Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0029] see figure 1 , the miniature magnetic positioning device in the present embodiment comprises the following components:
[0030] Metal detector array, an array composed of multiple metal detectors, such as 6×6, 8×8, 10×10 and other square arrays, is used to detect whether there are metal objects within its detection range. These metal detectors are Normally off state; the structure of a single metal detector is as follows figure 2 As shown, including coil 1, a square coil of 1cm to 2cm is usually used, and its detection range 2 is shown in the figure;
[0031] The vest at least includes a...

The invention discloses a micro positioning device and a method for positioning a micro in-vivo diagnosis and treatment device. The method comprises the following steps of: (1) arranging a metal detector array on the abdomen part of a human body; and (2) starting metal detectors in turn in the positioning process each time, and independently detecting whether a metal object appears or not in the detection range by using each metal detector; meanwhile, detecting the voltage change of each metal detector in real time, and recording the metal detector with the voltage change; and after all the metal detectors in the metal detector array finish detection, obtaining all the metal detectors with the voltage change, and calculating the central positions of the detection ranges of the metal detectors to obtain the current position of the micro in-vivo diagnosis and treatment device in the intestinal tract of the human body. The micro in-vivo diagnosis and treatment device can be simply, quickly and accurately positioned, and an object is not required to be arranged in the micro in-vivo diagnosis and treatment device, so that inner space is saved; and the micro positioning device is harmless to the human body and does not influence the normal work of a detected person.
Description
technical field [0001] The invention relates to the technical field of in vivo diagnosis and treatment, in particular to a micro 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 the key techn...
