Fig. 1 is structural representation of the present invention;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the right view of Fig. 1;
Fig. 4 is the left view of Fig. 1;
Fig. 5 is the top view of Fig. 1.
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 bottom is positioning seat 2.
In figure, show, the upper end of guiding face 1 is plane, and there is detent 3 plane inner side, and detent 3 is circular arc, and the peripheral shape of detent 3 and bigelow's septum periphery match.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 matches, guiding face 1 can not rotate with bigelow's septum, makes guiding face 1 and bigelow's septum realize circumferential registration.
In figure, show, the lateral surface of positioning seat 2 with the vertical outward flange along guiding face of plane of guiding face 1 to downward-extension, the medial surface of positioning seat 2 is connected with detent 3 edges of guiding face 1 inner side and along detent 3 edges to downward-extension, the medial surface of positioning seat 2 and femur periphery match.This structure is to make positioning seat 2 and femur realize circumferential registration equally, consistent with the effect of the detent 3 of guiding face 1, makes top and the bottom of the present invention can not swing simultaneously, more firm with 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 match.Draw-in groove 4 is looped around trochantinian top, and positioning seat 2 can not move down, and makes positioning seat 2 together with guiding face 1, realize the location of upper-lower position.
In figure, show, 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.
In figure, show on the lateral surface of positioning seat 2, there is fixing threaded hole 8, fixing threaded hole 8 is 2-4, and fixing threaded hole 8 is relative with femur outer wall.After operator uses locating rod 5 that osteotomy positioning and guiding platform is in place, with bolt, by fixing threaded hole 8, osteotomy positioning and guiding platform and femur are fixed, then dismantle the stock 7 of locating rod 5.
In figure, show, 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, near the front end of the guiding face 1 of lesser trochanter one side, is rectangular surfaces 10.It is to organize morely due to the tendon in 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.
In figure, show, in order to place easily osteotomy positioning and guiding platform, the both sides of the bottom draw-in groove of positioning seat around trochantinian fixing feet, be respectively short fixing feet 11, long fixing feet 12, near the length of the fixing feet of wedge angle 9 guiding face 1 one sides, be 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 to femur side, during placement, make detent 3 on guiding face 1 be looped around the periphery of bigelow's septum, make positioning seat 2 medial surface be looped around femur periphery simultaneously, 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 together with guiding face 1, realize the location of upper-lower position.
Behind location, with bolt, by fixing threaded hole 8, osteotomy positioning and guiding platform and femur are fixed, then the stock 7 of the lower locating rod 5 of dismounting.Behind location, the angle of guiding face 1 is identical with Osteotomy, and the upper surface that operator is adjacent to goose saw at guiding face 1 carries out osteotomy, makes Osteotomy smooth and meet the setting angle of hip prosthesis.
