Abstract

The invention discloses a reference data determination method, a reference data determination device and data processing equipment. The method comprises the steps of determining a feature point of a target object, wherein the feature point includes a caput femoris central point, a knee joint central point and an ankle joint central point of the target object; generating feature data according to the feature point, wherein the feature data include a distance I of a line segment I composed of the caput femoris central point and the knee joint central point, a distance II of a line segment II composed of the caput femoris central point and the ankle joint central point, and an angle of a rotation included angle formed with the caput femoris central point as a vertex and the line segments I and II as sides; and determining reference data based on the feature data, wherein the reference data are used for adjusting a lower limb alignment. According to the reference data determination method,the reference data determination device and the data processing equipment, the technical problem of relatively low accuracy of a positioning result caused by manual positioning of the lower limb alignment in a related technology is solved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular, to a method and device for determining reference data, and data processing equipment. Background technique [0002] During the operation of total knee arthroplasty, it is necessary to accurately locate the line of force of the lower limbs from the center of the femoral head to the center of the ankle joint. Therefore, during the operation of total knee arthroplasty, it is necessary to use a line of force measuring piece and see it under X-ray fluoroscopy. Observe whether the human body is satisfied with the line of force of the lower limbs, so as to judge whether the angle of osteotomy orthopedic is appropriate, and then adjust the varus angle of the human knee joint. In the prior art, because there is no corresponding fixing device clinically, two surgeons usually hold the two ends of the line of force measuring piece, so that one end of the line of force measuring...
