Abstract

The invention provides a measuring device for acetabulum filing and grinding. The measuring device for acetabulum filing and grinding comprises a magnetic field generator, a sensor device and a control device, wherein the magnetic field generator is used for generating a changing magnetic field in a space in which an acetabulum filing and grinding device is located; the sensor device is located inthe acetabulum filing and grinding device, the acetabulum filing and grinding device is located in the acetabulum, the acetabulum filing and grinding device and the sensor device are located in the magnetic field, and the sensor device is used for inducing the magnetic field to generate an induced electrical signal; and the control device communicates with the acetabulum filing and grinding device and determines filing and grinding parameters based on the induced electrical signal, and the filing and grinding parameters comprise at least one of a filing and grinding angle and a filing and grinding depth. The magnetic field generator applies the changing magnetic field in the space in which the acetabulum filing and grinding device is located, so that the sensor device installed in the acetabulum filing and grinding device can induce the changing magnetic field and then generate the induced electrical signal, the induced electrical signal can be an induced voltage signal or an inducedcurrent signal, and the control device determines the filing and grinding parameters according to the relevant characteristics of the generated induced electrical signal.

Description

technical field [0001] The present application relates to the medical field, in particular, to a measurement device and system for acetabular reaming. Background technique [0002] The total hip joint consists of the acetabulum and the femoral head. Acetabular reaming is the use of acetabular reamers to deepen and enlarge the acetabulum to form an acetabular bed that is convenient for installing an acetabular cup. Important factors affecting the stability of acetabular cup installation. Therefore, in practical applications, the anteversion and abduction angles of the acetabulum are used as the rasping angles of the acetabular reamer. [0003] Because it is difficult to locate the angle and depth of the file, it mainly relies on the professional level and experience of the staff to make subjective judgments, and the operation cannot be quantified. This will easily lead to a large deviation between the acetabular bed and the expected position, resulting in the position of th...
