Abstract
The invention discloses a wrist joint prosthesis which is used for being implanted into a damaged wrist joint. The wrist joint prosthesis is characterized in that a wrist joint broach fixed to a part to be implanted is included, the top of the wrist joint broach is sleeved with wrist joint interfacing, and the wrist joint interfacing is spherical, is contained in a spherical groove in a wrist joint cotyla head and can rotate in the groove of the wrist joint cotyla head. By means of the wrist joint prosthesis, a limb can be protected, a wrist joint is recovered and can conduct the movements of bending, stretching, expanding, collecting and ring rotation, the physiology of the wrist joint is met, and a patient can freely move as before; the wrist joint prosthesis broach and the wrist joint interfacing are matched, and safety and flexibility are achieved. The wrist joint prosthesis has the advantages of being easy and convenient to install, stable in structure, high in dislocation resisting performance and the like.
Description
Technical field
The present invention relates to a kind of artificial joint prosthesis, particularly relate to a kind of for carpal carpal joint prosthese.
Background technology
Carpal joint, is also called radiocarpal joint, is typical ellipsoid joint, and by the proximal joint face of the nut bone of hands, lunar and triquetrum as ball and socket joint, the meniscus below the carpal articular surface of radius and head of ulna is formed as glenoid fossa.
Carpal joint is the most complicated joint of human body, and numerous disease or wound can cause carpal chronic pain and afunction, as rheumatoid arthritis, and traumatic arthritis, osteoarthritis, suppurative arthritis tumor carpal joint etc.Current Therapeutic Method mainly adopts fusion of wrist joint, but is not also used for replacing artificial joint for wrist's prosthese of joint motion.
Summary of the invention
The object of the present invention is to provide that a kind of Stability Analysis of Structures, anti-dislocation are strong, the carpal joint prosthese of flexible rotating.
For achieving the above object, the concrete technical scheme of a kind of carpal joint prosthese of the present invention is:
A kind of carpal joint prosthese, for implanting in damage carpal joint, comprise the carpal joint broach being fixed on position to be implanted, the top movable of carpal joint broach is arranged with carpal joint interfacing, carpal joint interfacing is spherical, be contained in the ball recess on carpal joint mortar head, and can rotate in the groove of carpal joint mortar head.
Further, the bottom of carpal joint interfacing is provided with shrinkage pool, and the top of carpal joint broach is plugged in the shrinkage pool of carpal joint interfacing.
Further, the top of carpal joint broach is formed with needle handle, the needle point that carpal joint broach bottom is formed, and the external diameter of needle point is less than the external diameter of needle handle.
Further, the bore of the groove on carpal joint mortar head is less than the external diameter of carpal joint interfacing, and the groove on carpal joint mortar head is coated to be arranged on carpal joint interfacing.
Further, the inner surface of the groove on carpal joint mortar head is burnishing surface.
Further, the top of carpal joint mortar head is provided with the aciculiform projection inserting position to be implanted.
The advantage of carpal joint prosthese of the present invention is:
1) can limb be protected, recover carpal and bend, stretch, open up, receive and circumduction, meet carpal physiology, enable patient move freely as original;
2) carpal joint prosthese broach matches with carpal joint interfacing, and safety flexibly;
3) feature such as simple installation, Stability Analysis of Structures, anti-dislocation be strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of carpal joint prosthese of the present invention.
Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, further detailed description is done to carpal joint prosthese of the present invention.
As shown in Figure 1, it shows for carpal joint prosthese of the present invention, for implanting in damage carpal joint, comprise the carpal joint broach 1 being fixed on position to be implanted, the top movable of carpal joint broach 1 is arranged with carpal joint interfacing 2, and carpal joint interfacing 2 is spherical, be contained in the ball recess on carpal joint mortar head 3, and can rotate in the groove of carpal joint mortar head 3, with make carpal joint can do in the wrong, stretch, open up, receive and circumduction, the patient implanting carpal joint prosthese can recover picture originally freely move.It should be noted, in the present invention, carpal joint prosthese is made up of metal material and polythene material, and weight approximates the weight of skeleton, to make human body carpal joint prosthese easy to use.
Further, the bottom of carpal joint interfacing 2 is provided with shrinkage pool, and the top of carpal joint broach 1 is plugged in the shrinkage pool of carpal joint interfacing 2.In addition, the top of carpal joint broach 1 is formed with needle handle 11, the needle point 12 that carpal joint broach 1 bottom is formed, and needle point 12 inserts position to be implanted, and with fixing carpal joint prosthese, the external diameter of needle point 12 is less than the external diameter of needle handle 11.
Further, carpal joint interfacing 2 is spherical, with fit depressions spherical in carpal joint mortar head 3, rotate in the groove of carpal joint mortar head 3 to make carpal joint interfacing 2, it should be noted, in the present invention, the steradian of carpal joint interfacing 2 is preferably identical with the steradian of carpal joint mortar head 3 further groove, with make carpal joint interfacing 2 can in the groove of carpal joint mortar head 3 flexible rotating.
Further, the inner surface of the groove on carpal joint mortar head 3 is burnishing surface, reduces the surface roughness of groove, obtains light, even curface, more flexible to make carpal joint interfacing 2 rotate in the groove of carpal joint mortar head 3.In addition, the top of carpal joint mortar head 3 is provided with the aciculiform projection 31 inserting position to be implanted, with fixing carpal joint prosthese.
Further, carpal joint mortar head 3 further groove is provided with opening, carpal joint interfacing 2 enters in the groove of carpal joint mortar head 3 by opening, wherein, the internal diameter of opening is less than the internal diameter of carpal joint interfacing 2, is all arranged in carpal joint mortar head 3 to make most of structure of carpal joint interfacing, carpal joint interfacing 2 can be safer, stable in carpal joint mortar head 3 rotate, with complete in the wrong, stretch, open up, receive and circumduction, meet carpal physiological structure, improve the anti-dislocation of carpal joint prosthese.
Carpal joint prosthese of the present invention, can protect limb, recovers carpal and bend, stretches, opens up, receives and circumduction, meet carpal physiology, enable patient move freely as original; Carpal joint prosthese broach matches with carpal joint interfacing, and safety flexibly; The feature such as simple installation, Stability Analysis of Structures, anti-dislocation are strong.
Further describe invention has been by specific embodiment above; but it should be understood that; here concrete description; should not be construed as the restriction to the spirit and scope of the invention; one of ordinary skilled in the art to the various amendments that above-described embodiment is made, belongs to the scope that the present invention protects after reading this specification.
