Abstract
The utility model discloses a combined artificial hip joint connected by a screw handle. The handle part of the joint is connected with a neck base through a screw, a head is sheathed on the neck of the neck base, a liner is sheathed on the head, and then an acetabulum is sheathed on the liner. The joint is provided with two joint interfaces so as to reduce the friction between the prosthesis and the organism and to reduce the pain of the patient and extend the service life of the hip joint up to the hilt; in addition, the flexibility of the hip joint is increased, and the joint can not be loosened and sink easily without bone cement. The utility model is combined with other devices on operation with simple process, and each part can be changed without moving other parts; the utility model is suitably used for the oriental to carry on the operation on the transition of the whole hip joint.
Description
This utility model relates to a kind of artificial joint.
Known full hip artificial joint is an overall structure, is connected with human body and need uses bone cement.This joint connects insecure, loosening easily sinking, thus leading to complications, service life is short, must integral replacing during damage.
The purpose of this utility model is to provide a kind of combination type spiral shell handle full hip artificial joint, and this joint is connected firmly, and service time is long, must integral replacing during damage.
The purpose of this utility model is achieved in that shank connects the neck base by screw, and headgear is on the neck of neck base, and insert is on head, and acetabular bone is enclosed within on the liner.
The utlity model has following advantage:
1. be suitably for the Asians and do full hip-joint conversion operation.
2. have interface, two joints, can reduce the friction of prosthese and organism, can alleviate patient's the misery and the life-span of prolongation hip joint to greatest extent.Simultaneously, can also increase the mobility of hip joint.
3. do not need bone cement, thereby also just not because of the caused complication of bone cement.
4. shank is screw-like, be screwed into femoral bone cavitas medullaris after, can with femur medial wall tight connecting, stress distribution is even, is not easy to occur loosening and sinks.
5. combination accessory, operation technique is easy, grasps easily, is convenient to vast basic hospital and uses.
6. acetabular bone is simple and practical, and the mortar hole with mortar handle is fixed on the human body bone edge with screw, has fixedly, is difficult for loosening advantage.
7. by the combination of five parts, when a part need be changed, only change this part and needn't all change.
Elaborate below in conjunction with drawings and Examples.
Accompanying drawing is a structure chart of the present utility model.
1. acetabular bones among the figure, 2. the hole handle, 3. screw, 4. liner, 5., 6. neck, 7. screw, 8. tooth, 9. screw, 10.V shape groove, 11. screws, 12. posts, 13. teeth, 14. holders, 15. handles.
