Keep off end 11.In this way, stop end 11 effectively can carry out backstop to the force section 20 moved along the direction far from connecting rod 13, really
It protects force section 20 and generates enough momentums at stop end 11 to provide drag force for femoral stem 2, taken to improve femoral stem
Go out the use reliability of device 3.
Optionally, stop end 11 is the backstop convex block being removably disposed in connecting rod 13.In this way, being convenient for force section
Under 20 are installed in connecting rod 13 or dismantle from connecting rod 13, be conducive to repair replacement to connecting rod 13.
Specifically, as a kind of alternative embodiment, backstop convex block is nut, the one of the remotely located bar 12 of connecting rod 13
There is the peripheral surface at end screw thread, nut to be removably threadedly coupled with connecting rod 13.
Certainly, in order to ensure that backstop convex block steadily carries out backstop to force section 20, backstop convex block is fixedly installed.
As shown in Figure 1, femoral stem withdrawing device 3 further includes buffering stop configurations 40, locating rod 12 is by buffering backstop knot
Structure 40 is connect with connecting rod 13, and 20 backstop of force section is at buffering stop configurations 40.In this way, buffering stop configurations 40 are effectively delayed
It has solved force section 20 and has fallen the impact force generated to human femur under loading 1 after rise, avoided and secondary damage is generated to human femur under loading 1, improve
The use reliability of femoral stem withdrawing device 3.
As shown in Fig. 2, hook support 30 includes limit section 31, bending section 32 and hook support segment 33 connected in sequence, section 31 is limited
Installation through-hole 311 is offered, hook support 30 is set in by installation through-hole 311 in locating rod 12, and bending section 32 is towards femoral stem 2
The side at place extends, and is offered and 2 clasp joint of femoral stem or the evacuation notch 331 abutted on hook support segment 33.
The present invention Fig. 1 shown in alternative embodiment in, the hook support segment 33 of hook support 30 away from the end of human femur under loading 1
Face is abutted with femoral stem 2, in this way, can the power that generated at stop end 11 steadily be passed to femoral stem 2 by hook support 30.
Optionally, in order to ensure that hook support 30 steadily clasp joint or is connected at femoral stem 2, the extending direction of hook support segment 33
Has slanted angle between the axis direction of locating rod 12.
As shown in Figure 1, femoral stem withdrawing device 3 includes limited block 50, limited block 50 is arranged in locating rod 12 and and hook
The end face of the first end away from locating rod 12 of support 30 abuts.In this way, effectively limiting hook support 30 in locating rod 12
Moving displacement, avoid using femoral stem withdrawing device 3 when, hook support 30 shakes.
Optionally, locating rod 12 and connecting rod 13 are coaxially disposed.In this way, being convenient for femoral stem withdrawing device 3 and human body stock
Bone 1 position, make femoral stem withdrawing device 3 efficiently, reliably transmit power.
Optionally, force section 20 is sliding hammer.
As shown in Figure 1, it further includes fixed that the end face of the first end of locating rod 12, which has hatch frame, femoral stem withdrawing device 3,
Position portion 60, positioning region 60 are telescopically disposed in locating rod 12 and are stretched out by hatch frame or be retracted into locating rod 12.In this way,
Femoral stem withdrawing device 3 is headed into the shoulder location hole of femoral stem 2 by the end of positioning region 60 to generate pressure, by femur
It is positioned between handle withdrawing device 3 and femoral stem 2.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect:Use this hair
Bright femoral stem withdrawing device 3 changes the mode that femoral stem is extracted in traditional hip revision operation, saves medical work
