Abstract

The invention discloses a medical three-dimensional positioning guider for an orthopedic surgery. The medical three-dimensional positioning guider is provided with two measuring systems comprising a static measuring unit and a dynamic measuring unit; an azimuth angle and a sagittal angle can be measured in real time in various environments; the static measuring unit provides a relatively static reference coordinate system for the dynamic measuring unit; the medical three-dimensional positioning guider is always perpendicular to the skin of a patient; deviation cannot be caused even if the patient moves; medical staffs can obtain real-time accurate position information; and the success rate of the orthopedic surgery and other surgeries is increased. By using the portable three-dimensional positioning guider for the orthopedic surgery, position conditions of an instrument can be displayed in real time, the medical staffs can accurately determine the sizes of the sagittal angle and the azimuth angle between the position of the instrument and the skin of the patient clinically, and accurate guiding is realized; and the medical three-dimensional positioning guider for the orthopedic surgery can be calibrated in real time, and various human errors are avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a three-dimensional positioning guide for medical orthopedic surgery. Background technique [0002] In the existing orthopedic surgery operations, the puncture technique is widely used, especially in the transpedicular operation of spinal surgery, the puncture must be performed in the only correct bony channel, so that the screw or bone cement, etc. The placement position is accurate, so the clinician is required to determine the sagittal angle and azimuth angle of the instrument operation with high precision. However, at present, the angle is generally estimated roughly based on the experience of the doctor's visual observation. Therefore, even an experienced doctor cannot guarantee that the angle is completely correct or basically accurate. The literature reports that the misplacement rate of pedicle screws ranges from 10% to 33.7%, and the complications are serious. ...
