Abstract
The invention discloses a knee-joint internal and external rotating angle measurer used in the knee-joint surface replacement technology for a surgery. According to the knee-joint surface replacement technology, due to the moderate outward rotation of a prosthesis on the thighbone side, a buckling clearance and a straightening clearance can be well matched, and the complication caused by poor motion track of the patella is reduced. The knee-joint internal and external rotating angle measurer is composed of a rear condyle positioning frame and an angle ruler. A rotating shaft of the angle ruler is located in a longitudinal groove in the rear condyle positioning frame, and the angle ruler can horizontally move up and down and can rotate around the shaft, so that the angles of different skeletons are measured. According to the knee-joint internal and external rotating angle measurer, on the basis of the actual requirement in the knee-joint replacement technology, the knee-joint internal and external rotating angle measurer is developed, the knee-joint internal and external rotating angle measurer is simple in structure, accurate in measurement, convenient to use and universal during the surgery, measurement of the knee-joint internal and external rotation angles during the surgery is achieved, and supports are provided for accurate implementation of the surgery.
Description
Technical field
The present invention relates to a kind of angle measurement unit using for operating knee joint surface replacement art, particularly relate to outward turning angle measuring device in a kind of knee joint.
Background technology
In knee joint surface replacement art, the application of the size of condyle of femur outward turning angle in total knee arthroplasty obtained the concern of Chinese scholars.In art, the flexing gap that the outward turning of femur side prosthesis appropriateness can make joint with stretch gap and obtain good mating, reduce the bad complication causing of patellar motion trace, comprise that shock, the patella of prosthetic loosening, patella and femur moves lax even dislocation, rupture of patellar tendon etc. outward.Line of reference and the inspection method of measuring the distal femur anglec of rotation have multiple, the most frequently used line of reference to comprise femoral-posterior condyles line (PCL), epicondyle line (SEA), clinical epicondyle line (CTEA), front and back axis (Whiteside line).Wherein at present Chinese scholars thinks that epicondyle line sees kneed rotation axis as, and position is comparatively constant, with this line and the formed femoral-posterior condyles of postartis line angle (PCA), be to measure distal femur rotation comparatively accurately and in operation to hold wield reference.
Clinical statistics thinks, femoral-posterior condyles angle (PCA) exists sizable difference at individuality: first have race difference, Hong Kong author reports that the femur outward turning angle of factor analysis is obviously greater than external data; Between gender, also there are differences, therefore, extremely important to outward turning angle measuring in knee joint, but at present also for there being specific purpose tool to carry out measuring in art.
Summary of the invention
For problems of the prior art, the present invention is based in knee replacements to obtain actual needs, develop outward turning angle measuring in a kind of knee joint, it can directly measure the femoral-posterior condyles angle (PCA) of any individual, thereby provide a kind of simple in structure, measure can be general in accurate, easy to use, art instrument, realize in the art of the inside and outside swing angle degree of knee joint and measuring, for performing the operation, accurately implement to provide support.
For achieving the above object, the present invention takes following design:
An outward turning angle measuring device in knee joint, is comprised of pedestal 1, angle measuring scale 2.
Described pedestal 1 is comprised of antetheca 11, rear wall 12, an armful condyle plate 14.
Further, between pedestal 1 front and rear wall 11,12, there are longitudinally lower groove 15, antetheca to have on longitudinally upper groove 16, rear wall and have groove 17.
Described angle measuring scale 2 is comprised of side plate 22, the graduated disc 24 of rotating shaft 21, symmetrical distribution.
Further, under the side direction of angle measuring scale 2 between the front and rear wall 11,12 of described pedestal 1 in groove 13.
Further, the rotating shaft 21 of angle measuring scale 2 is positioned at the longitudinally lower groove 15 of the front and rear wall 11,12 of pedestal, and angle measuring scale not only can move up and down along pedestal 1 like this, can pivot simultaneously.
Further, on the side plate 22 of angle measuring scale 2, have side plate groove 23, object realizes line at the epicondyle line (SEA) 32 with human femur under loading condyle.
Further, the graduated disc 24 of angle measuring scale 2 is comprised of symmetrical groove, middle scale is 0 degree, each scale is 1 degree, the quantity of groove is 8, the range that in this knee joint, outward turning angle measuring device is measured is 8 degree, and the angle showing between groove 17 in graduated disc 24 and base rear wall is measured angle value.
While using the interior outward turning angle measuring device of this knee joint, fit with human femur under loading condyle far-end 31 respectively in condyle plate 14 both sides of embracing of described pedestal 1, mobile also rotation angle measurement chi 2, side plate groove 23 is overlapped with the epicondyle line (SEA) 32 of human femur under loading condyle, now, the graduated disc 24 of angle measurement equipment 2 must have groove 17 overlaids on a groove and pedestal 1 rear wall, is now swing angle degree, i.e. femoral-posterior condyles angle (PCA) inside and outside knee joint with the angle of the equitant groove of groove 17 institute labelling.
The present invention is based in knee replacements to obtain actual needs, develop outward turning angle measuring in a kind of knee joint, object provide a kind of simple in structure, measure can be general in accurate, easy to use, art instrument, realize in the art of the inside and outside swing angle degree of knee joint and measuring, for performing the operation, accurately implement to provide support; This device can be realized Reusability, further saves cost.
