The present application provides a measuring device for acetabular reaming, which includes: a magnetic field generator, used to generate a changing magnetic field in the space where the acetabular reaming device is located; a sensor device, located in the acetabular reaming device, The acetabular reaming device is located in the acetabulum, the acetabular reaming device and the sensor device are located in the magnetic field, the sensor device is used to induce the magnetic field to generate an induction electrical signal; the control device communicates with the acetabular reaming device, and determines the rasp according to the induction electrical signal parameter, the filing parameter includes at least one of a filing angle and a filing depth. The magnetic field generator applies a changing magnetic field in the space where the acetabular reaming device is located, so that the sensor device installed in the acetabular reaming device senses the changing magnetic field, and then generates an induction electrical signal, which can be an induction The voltage signal can also be an induced current signal, and the control device determines the filing 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...
