Summary of the invention
Problem to be solved in the utility model is: overcome the deficiencies in the prior art, and provide a kind of artificial knuckle, structure is simple, reasonable in design, easy for installation, the flexion and extension in joint can be made well to be recovered, the stability in joint can be ensured again, prevent artificial knuckle from producing and rotate and loosen.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of artificial knuckle, comprise and be connected to into the joint prosthese far away on joint prosthese into joint prosthese and hinge, describedly enter to save prosthese and far save the side of prosthese towards the centre of the palm and be provided with a support component, one end of described support component is movably connected on the side into joint prosthese towards the centre of the palm, and the other end of described support component is movably connected on the side of joint prosthese far away towards the centre of the palm; Describedly enter to save prosthese and be provided with a limit element with the side far save the prosthese centre of the palm dorsad, the side into the joint prosthese centre of the palm is dorsad fixed in one end of described limit element, and the other end of described limit element is fixed on the side far saving the prosthese centre of the palm dorsad.
Further, described support component is an atmospheric pressure pole, and the end of the motion bar of described atmospheric pressure pole is hinged and is connected to the side of joint prosthese far away towards the centre of the palm, and the end of the stationary magazine creel of described atmospheric pressure pole is hinged the side be connected to into joint prosthese towards the centre of the palm.
Further, described in enter to save prosthese end be the concave surface of a circular arc, the end of described joint prosthese far away is the convex surface of a circular arc, and described convex surface is positioned at concave surface.
Further, described in enter to save on prosthese and joint prosthese far away and be respectively equipped with groove one and groove two, described groove one communicates with groove two, fixes the two ends of limit element in described groove one and groove two respectively, and is positioned at the cell body that groove one and groove two formed.
Further, enter to save prosthese described in and far save prosthese and be provided with screwed hole.
Further, enter to save prosthese described in and far save prosthese and be provided with air-vent.
Further, the material entering to save prosthese described in is high hinge ultra-high molecular weight polyethylene.
Further, the material of described joint prosthese far away is CoCrMo alloy.
The advantage that this utility model has and good effect are:
This utility model structure is simple, reasonable in design, easy for installation, entering to save prosthese and far saving the side of prosthese towards the centre of the palm and be provided with a support component, a limit element is provided with entering to save prosthese with the side far saving the prosthese centre of the palm dorsad, the flexion and extension in joint can be made well to be recovered, the stability in joint can be ensured again, prevent artificial knuckle from producing and rotate and loosen.

Detailed description of the invention
As Figure 1-4, a kind of artificial knuckle, comprise and being connected to into the joint prosthese 2 far away on joint prosthese 1 into joint prosthese 1 and hinge, the material entering to save prosthese 1 is high hinge ultra-high molecular weight polyethylene, and the material of joint prosthese 2 far away is CoCrMo alloy; Enter to save prosthese 1 and far save the side of prosthese 2 towards the centre of the palm and be provided with an atmospheric pressure pole 3, the end of the motion bar of atmospheric pressure pole 3 is hinged to be connected to and far saves the side of prosthese 2 towards the centre of the palm, and the end of the stationary magazine creel of atmospheric pressure pole 3 is hinged the side be connected to into joint prosthese 1 towards the centre of the palm; Enter to save prosthese 1 and be provided with a limit element 4 with the side far saving prosthese 2 centre of the palm dorsad, the side into joint prosthese 1 centre of the palm is dorsad fixed in one end of limit element 4, the other end of limit element 4 is fixed on the side in the joint prosthese 2 far away centre of the palm dorsad, enter to save on prosthese 1 and joint prosthese 2 far away and be respectively equipped with groove 1 and groove 28, groove 1 communicates with groove 28, fix the two ends of limit element 4 in groove 1 and groove 28 respectively, and be positioned at the cell body that groove 1 formed with groove 28; The end entering to save prosthese 1 is the concave surface 5 of a circular arc, and the end of joint prosthese 2 far away is the convex surface 6 of a circular arc, and convex surface 6 is positioned at concave surface 5, enters to save prosthese 1 and far save prosthese 2 to be provided with screwed hole 9 and air-vent 10.
The work process of this example: will enter to save prosthese 1 and be fixed on human body proximal phalanx head; be fixed on human body distal phalanx head by far saving prosthese 2; stretch out when atmospheric pressure pole 3 or compress; play the effect driven with fixing; articulations digitorum manus is made and being stretched or flexure operation, and limit element 4 can play a protective role when articulations digitorum manus bends simultaneously, and the flexion and extension in joint can be made well to be recovered; the stability in joint can be ensured again, prevent artificial knuckle from producing and rotate and loosen.
