Abstract
The of the utility model is used for femoral stem of same contained angle of front and back side design among the orthopedics hip joint replacement surgery, characterized in that are on the cross section, and the curved contained angle of cross section front side and rear side is 70-179. This design can be sunk by the better femoral stem that prevents, reduces the possibility of rebuilding.
Description
Technical field
This utility model relates to the implant in a kind of medical apparatus and instruments, particularly a kind of femoral stem designing identical angle for the side, front and back in orthopaedics hip replacement surgery.
Background technology
In orthopaedics hip replacement surgery, need to use femoral stem and substitute the hip joint that need repair, need in operation process to remove part spongy bone, form a die cavity matched with femoral stem, front and back sides (1) and the die cavity wall pressure of femoral stem (Fig. 1,2) are joined, and form stable, reliable press-fit relationship.Can better prevent femoral stem from sinking.Conventional femoral stem (Fig. 2,3) front and back sides (1) is designed to pancake, does not prevent the function of sinking.
Summary of the invention
This utility model patent, for the defect of prior art, provides side, a kind of front and back to design the femoral stem of identical angle, prevents femoral stem from sinking, and reduces the probability of overhauling.
Accompanying drawing explanation
Fig. 1,2 is for designing the femoral stem schematic diagram of identical angle in side, front and back;
Fig. 3,4 is conventional femoral stem.
Detailed description of the invention
Below in conjunction with drawings and embodiments, the utility model will be further described.
As shown in Figure 1, 2, this utility model is the femoral stem that identical angle is designed in side, front and back, it is characterized by cross section, on front side of cross section and the angle of rear side arc be 70 ° ~ 179 °.This design can better prevent femoral stem from sinking, and reduces the probability of overhauling.
Claims (1)
1. before and after, the femoral stem of identical angle is designed in side, to be useful in the operation of orthopaedics artificial hip joint replacing in implant into body, to it is characterized by cross section, on front side of cross section and the angle of rear side arc be 70 ° ~ 179 °.
