Description
Technical field
This utility model relates to orthopaedics medical instruments field, specifically a kind of artificial ankle joint.
Background technology
As everyone knows, replace the pathological changes of ankle joint or injured articular surface with prosthetic component, make patient to recover proper motion.General artificial ankle joint comprises the tibial component of patients with implantation tibia and the astragalus parts of patients with implantation astragalus, in addition, can provide bearing insert between tibial component and astragalus parts.But the artificial ankle joint of prior art is fixing can not rotate, or degree of freedom can only plantar flexion or dorsiflex in limited range.These ankle joint are only applicable to walk on more smooth road surface.When road surface is rugged and rough, the meeting of these ankle joint is because cannot realizing the varus of ankle joint and turning up, and nature or walking are steady to cause patient to walk appearance, and also do not have buffer unit, comfort level is poor, poor stability.Therefore, need to develop a kind of artificial ankle joint, under the prerequisite ensureing ankle joint degree of freedom, its comfort level is high, and safety is high, and action nature, is adapted at walking in various road surface.
Summary of the invention
Problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of structure simple, reasonable in design, simple to operate, under the prerequisite ensureing ankle joint degree of freedom, its comfort level is high, there is certain cushioning effect, safety is high, and action nature, is adapted at the artificial ankle joint walked in various road surface.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of artificial ankle joint, comprise an interlocking and merge handle, a joint ball connecting plate is fixed in the bottom that described interlocking merges handle, the universal connection one in the bottom joint ball of described joint ball connecting plate, described joint ball is the housing of a semicircular structure, Open Side Down for described joint ball, the lower limb of described joint ball is arranged with left connecting portion and right connecting portion, flexible member is connected with between described joint ball connecting plate and the upper surface of joint ball, support component is provided with between described joint ball connecting plate and the rear end of joint ball, one end of described support component is fixed on joint ball connecting plate, the other end of described support component is movably connected on the rear end of joint ball.
Further, described joint ball connecting plate is connected by a joint coupling with the top of joint ball.
Further, the bottom of described joint ball connecting plate is provided with a groove, and the top of described joint ball is positioned at groove.
Further, the surface of described joint ball has air-vent.
Further, the surface of described joint ball has screw, has inter-locking screw to pass in described screw.
Further, described left connecting portion and right connecting portion have fixing hole.
Further, described interlocking merges handle material is Ti-6Al-4V.
Further, the material of described inter-locking screw is Ti-6Al-4V.
Further, the material of described joint ball is CoCrMo alloy.
The advantage that this utility model has and good effect are:
This utility model structure is simple, reasonable in design, simple to operate, and under the prerequisite ensureing ankle joint degree of freedom, its comfort level is high, and have certain cushioning effect, safety is high, and action nature, is adapted at walking in various road surface.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model artificial ankle joint.
Fig. 2 is the right view of this utility model artificial ankle joint.
Fig. 3 is 1/4th sectional views of the joint ball of this utility model artificial ankle joint.
In figure: 1, interlocking merges handle; 2, joint ball connecting plate; 3, joint coupling; 4, joint ball; 5, groove; 6, air-vent; 7, left connecting portion; 8, right connecting portion; 9, fixing hole; 10, screw; 11, flexible member; 12, support component; 13, inter-locking screw.
Detailed description of the invention
As Fig. 1, 2, shown in 3, a kind of artificial ankle joint, comprise an interlocking and merge handle 1, the material that interlocking merges handle 1 is Ti-6Al-4V, a joint ball connecting plate 2 is fixed in the bottom that interlocking merges handle 1, the bottom of joint ball connecting plate 2 is by a joint coupling 3 universal connection one joint ball 4, the material of joint ball 4 is CoCrMo alloy, the bottom of joint ball connecting plate 2 is provided with a groove 5, the top of joint ball 4 is positioned at groove 5, joint ball 4 is the housing of a semicircular structure, the surface of joint ball 4 has air-vent 6, Open Side Down for joint ball 4, the lower limb of joint ball 4 is arranged with left connecting portion 7 and right connecting portion 8, left connecting portion 7 and right connecting portion 8 have fixing hole 9, the surface of joint ball 4 has screw 10, inter-locking screw 13 is had to pass in screw 10, the material of inter-locking screw 13 is Ti-6Al-4V, flexible member 11 is connected with between the upper surface of joint ball connecting plate 2 and joint ball 4, support component 12 is provided with between the rear end of joint ball connecting plate 2 and joint ball 4, one end of support component 12 is fixed on joint ball connecting plate 2, the other end of support component 12 is movably connected on the rear end of joint ball 4.
The work process of this example: during use, merges by interlocking with handle 1 and is fixed on the tibia of patient, be placed on the astragalus of patient by joint ball 4 simultaneously, and is fixed through screw 10 with inter-locking screw 13.The bottom of joint ball connecting plate 2 is by the universal connection joint ball 4 of joint coupling 3, patient can freely swing ankle joint, owing to being provided with support component 12 between joint ball connecting plate 2 and the rear end of joint ball 4, under the prerequisite ensureing ankle joint degree of freedom, its comfort level is high; And be connected with flexible member 11 between joint ball connecting plate 2 and the upper surface of joint ball 4, have certain cushioning effect, safety is high, action nature, is adapted at walking in various road surface.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiments of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to this utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
