[0002] At present, the medical system shows that the intramedullary nail positioning hole needs to be positioned under the X-ray machine before drilling the positioning hole in the human bone during orthopedic surgery. The X-rays emitted by the X-ray machine will cause harm to medical staff and patients during the operation. Affects human health. Although there is a far and near intramedullary nail aimer, its positioning accuracy is poor, the operation is cumbersome during the operation, the operation time is long, and the positioning hole wound is added during the operation, which increases the pain of the patient.
[0003] The applicant of this patent once applied for "medical laser position measuring instrument and its position measuring method", patent application number: "03152995.X". Accurate position in the body, using laser to correct the surgical site, can perform surgery quickly and accurately, but it is necessary to cut a large incision on the patient's skin and use a spreader to open it, so that the light can pass through the bone layer and form a significant Facula, if the surgical patient has a large amount of incision bleeding, the formed facula will be blurred, and it is difficult for the doctor to distinguish the center of the facula, which will affect the accuracy of the surgical perforation, and a large skin incision will affect the healing time of the wound. It can also cause excessive scarring

Description
technical field [0001] The medical magnetic positioning instrument of the present invention relates to a medical magnetic detection, positioning and displaying instrument, especially suitable for orthopedic operations indicating the specific position of the intramedullary nail positioning hole on the bone cavity and detection, positioning and displaying devices in other surgical operations . Background technique [0002] At present, the medical system shows that the intramedullary nail positioning hole needs to be positioned under the X-ray machine before drilling the positioning hole in the human bone during orthopedic surgery. The X-rays emitted by the X-ray machine will cause harm to medical staff and patients during the operation. Affecting human health, although there is a kind of intramedullary nail far and near end aimer now, its positioning accuracy is poor, operation is loaded down with trivial details in the operation process, operation time is long, increases posi...
