Embodiment Construction

[0014] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0015] A knee joint osteotomy angle measuring device designed in the present invention includes a bottom plate 1 and a top plate 2. The bottom plate 1 and the top plate 2 are hinged on their sides, and two sets of pressure sensors are provided at the top plate 2 and the femoral head of the knee joint. 3. The knee joint osteotomy angle measuring device further includes a lifting mechanism 4 for rotating and lifting the top plate 2 along the hinge point.

[0016] The lifting mechanism 4 may be a lifting pliers, the end of which is inserted between the bottom plate 1 and the top plate 2. The bottom plate 1 and the top plate 2 are respectively provided with fixing grooves 6 for inserting the ends of the lifting mechanism 4. The lifting mechanism 4 is provided with a rack mechanism 5 for accurately controlling the lifting angle. The liftin...

Abstract

The invention discloses a knee joint osteotomy angle measuring device comprises a bottom plate and a top plate, and side edges of the bottom plate and the top plate are hinged on to each other; a part, corresponding to a knee joint femoral head, of the top plate is provided with two groups of pressure sensors; the knee joint osteotomy angle measuring device further comprises a lifting mechanism which is used for rotating and lifting the top plate along a hinge point, and the pressure sensors are array type pressure sensors. The knee joint osteotomy angle measuring device disclosed in the invention can be used for conveniently and rapidly measuring an osteotomy angle during knee joint replacement, success rates of operations can be improved, and operation time can be shortened.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a knee joint osteotomy angle measuring device. Background technique [0002] The knee joint is the most complex multi-axial motion joint in human anatomy. With the advent of the aging society in our country, more and more patients suffer from knee joint diseases. At present, artificial knee joint replacement has become a common clinical method for the treatment of various advanced complex knee joint diseases, and has achieved good results. However, with the widespread development of the operation, the problems caused by it are also increasing. According to reports, the incidence of patellofemoral complications after total knee arthroplasty is 1.5%-12%, accounting for 50% of the reasons for artificial knee revision, and becoming one of the most common reasons for knee revision. The reconstruction of the accurate rotational force line of the femoral prosthesis during t...
