In figure, labelling is as follows: guiding face 1, positioning seat 2, detent 3, draw-in groove 4, locating rod 5, screw shell 6, stock 7, fixing threaded hole 8, wedge angle 9, rectangular surfaces 10, short fixing feet 11, long fixing feet 12.
The specific embodiment
The top of bigelow's septum osteotomy positioning and guiding platform of the present invention is guiding face 1, and the bottom is positioning seat 2.
Show in figure, the upper end of guiding face 1 is the plane, and there is detent 3 inboard, plane, and detent 3 is circular arc, and the peripheral shape of detent 3 and bigelow's septum periphery are complementary.During use, detent 3 is looped around the periphery of bigelow's septum, and because peripheral shape and the neck of femur periphery of detent 3 is complementary, guiding face 1 can not rotate with bigelow's septum, makes guiding face 1 and bigelow's septum realize circumferential registration.
Show in figure, the lateral surface of positioning seat 2 outward flange along guiding face vertical with the plane of guiding face 1 is to downward-extension, detent 3 edges of the medial surface of positioning seat 2 and guiding face 1 inboard are connected and along detent 3 edges to downward-extension, the medial surface of positioning seat 2 and femur periphery are complementary.This structure is to make positioning seat 2 and femur realize circumferential registration equally, and is consistent with the effect of the detent 3 of guiding face 1, and top and the bottom of the present invention can not swung, more firm with the femur location.
Draw-in groove 4 is arranged at the bottom of positioning seat 2, and the periphery of draw-in groove 4 and lesser trochanter top circumference are complementary.Draw-in groove 4 is looped around trochantinian top, and positioning seat 2 can not move down, and makes positioning seat 2 realize the location of upper-lower position together with guiding face 1.
Show in figure, locating rod 5 is installed on the lateral surface of positioning seat 2, locating rod 5 is comprised of screw shell 6 and stock 7, screw shell 6 is fixedly connected on the lateral surface of positioning seat 2, the front end of stock 7 has external screw thread, and stock 7 front ends are spun on screw shell, can dismantle and be connected.The effect of locating rod 5 is to make the convenient osteotomy positioning and guiding platform of placing of operator, and dismounting stock 7 after fixing after placing is convenient to carry out bone-culting operation.
Show in figure that fixing threaded hole 8 is arranged on the lateral surface of positioning seat 2, fixing threaded hole 8 is 2-4, and fixing threaded hole 8 is relative with the femur outer wall.After operator uses locating rod 5 that osteotomy positioning and guiding platform is in place, osteotomy positioning and guiding platform and femur are fixed by fixing threaded hole 8 with bolt, then dismantle the stock 7 of locating rod 5.
Show in figure, the guiding face 1 of detent 3 both sides is clamped in respectively the periphery both sides of bigelow's septum, and wherein the front end away from the guiding face 1 of lesser trochanter one side is wedge angle 9, is rectangular surfaces 10 near the front end of the guiding face 1 of lesser trochanter one side.It is to organize morely due to the tendon on this side femur wall and blood vessel etc. that the front end of guiding face 1 adopts the reason of wedge angle 9, adopts wedge angle 9 can be inserted into easily in the gap of tendon and goes.
Show in figure, in order to place easily osteotomy positioning and guiding platform, the both sides of the bottom draw-in groove of positioning seat be respectively short fixing feet 11, long fixing feet 12 around trochantinian fixing feet, near the length of the fixing feet of wedge angle 9 guiding face 1 one sides less than the length near the fixing feet of rectangle 10 guiding face 1 one sides.
Using method of the present invention is as follows:
The hand-held locating rod 5 of operator, osteotomy positioning and guiding platform is placed on the femur side, make detent 3 on guiding face 1 be looped around the periphery of bigelow's septum during placement, make simultaneously positioning seat 2 medial surface be looped around the femur periphery, allow guiding face 1 and positioning seat 2 realize circumferential registration with femur.Meanwhile, operator will make draw-in groove 4 be looped around trochantinian top, and positioning seat 2 can not move down, and makes positioning seat 2 realize the location of upper-lower position together with guiding face 1.
Behind the location, osteotomy positioning and guiding platform and femur are fixed by fixing threaded hole 8 with bolt, then the stock 7 of the lower locating rod 5 of dismounting.Behind the location, the angle of guiding face 1 is identical with Osteotomy, and operator carries out osteotomy with the upper surface that goose saw is adjacent at guiding face 1, makes Osteotomy smooth and satisfy the setting angle of hip prosthesis.
