In figure, labelling is as follows: guide table 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, osteotomy guide slit 13.
The specific embodiment
The top of bigelow's septum bone cutting positioner of the present invention is guide table 1, and the bottom is positioning seat 2.
Show in figure, guide table 1 is circular arc, and the circular arc inboard of guide table 1 is detent 3, and the peripheral shape of detent 3 and bigelow's septum periphery are complementary, and play positioning action.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, guide table 1 can not rotate with bigelow's septum, makes guide table 1 and bigelow's septum realize circumferential registration.
Show in figure, there is horizontal osteotomy guide slit 13 at the middle part of guide table 1, and the gap width of osteotomy guide slit 13 and the saw kerf of goose saw are complementary.The effect of osteotomy guide slit 13 is direct of travels of guiding goose saw, and goose saw carries out forward osteotomy along osteotomy guide slit 13, and due to the constraint of lower limb to goose saw on osteotomy guide slit 13, goose saw can not swing up and down, and makes Osteotomy neat, straight.
Show in figure, the lateral surface of positioning seat 2 outward flange along guide table 1 vertical with guide table 1 is to downward-extension, detent 3 edges of the medial surface of positioning seat 2 and guide table 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 guide table 1, and top and the bottom of the present invention can not swung, more firm with the femur location.
Show in figure, 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 can not move left and right, and makes positioning seat 2 realize the location of up and down and position, left and right together with guide table 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 bone cutting positioner of placing of operator, after placing, bone cutting positioner is fixed, and then the lower stock 7 of dismounting, be convenient to carry out the osteotomy 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 bone cutting positioner is in place, bone cutting positioner and femur are fixed by fixing threaded hole 8 with bolt.
Show in figure, the guide table 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 guide table 1 of lesser trochanter one side is wedge angle 9, is rectangular surfaces 10 near the front end of the guide table 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 guide table 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 bone cutting positioner, 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 guide table 1 one sides less than the length near the fixing feet of rectangle 10 guide table 1 one sides.
Using method of the present invention is as follows:
The hand-held locating rod 5 of operator, femur side with the bone cutting positioner placement, make detent 3 on guide table 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 guide table 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 up and down and position, left and right together with guide table 1.
Behind the location, bone cutting positioner 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 guide table 1 is identical with Osteotomy, operator carries out forward osteotomy with goose saw along osteotomy guide slit 13, due to the constraint of lower limb to goose saw on osteotomy guide slit 13, goose saw can not swing up and down, make Osteotomy neat, straight, and satisfy the setting angle of hip prosthesis.
