Abstract
This application discloses a kind of artificial joint, comprise joint rotating part, the joint connecting portion of articular branches support part and connection joint rotating part and articular branches support part, articular branches support part upper side is provided with protuberance, articular branches support part is provided with multiple hole, and articular branches support part inner hollow is arranged.Thus, articular branches support part upper side is provided with projecting member, increases the coverage rate with skeleton, thus eliminate the effect of bone cement, in addition articular branches support part is provided with multiple hole, and articular branches support part inner hollow is arranged, and allows osseous tissue penetrate into artificial joint inside by hole, and the position of hole is set, increase the support force of articular branches support part, structure is simple, utilizes the change of artificial joint structure, can be fixedly connected with bone fast, the feature that the life-span is long.
Description
Technical field
This utility model relates to medical devices, particularly relates to a kind of artificial joint.
Background technology
Joint is the hinge of human motion, and due to wound or pathological changes, possibility " scrapping ", at this moment doctor often " will scrap " arthrectomy, change artificial joint.Human synovial is the great-hearted organ of tool, and the artificial joint changed is all unvital prosthese.
Artificial joint replacement is excised by the articular surface of wear-out failure, and as dress facing, implantable artificial joint, makes it recover normally level and smooth articular surface.After existing joint replacement completes, adopt bone cement bone and artificial joint to be fixed, but medullary cavity inner high voltage can be caused once in a while during Cement fixation, cause fat drop intravasation, cause thromboembolism.In addition, it is different from skeleton after all, and the time is excessively of a specified duration, and artificial joint still may loosen.
Utility model content
The purpose of this utility model is to provide a kind of artificial joint, solves one or more in above-mentioned prior art problem.
According to an aspect of the present utility model, a kind of artificial joint is provided, comprise joint rotating part, the joint connecting portion of articular branches support part and connection joint rotating part and articular branches support part, articular branches support part is provided with protuberance near the side of upper end, articular branches support part is provided with multiple hole, and articular branches support part inner hollow is arranged.
This utility model is provided with projecting member by articular branches support part upper side, increase the coverage rate with skeleton, thus eliminate the effect of bone cement, in addition articular branches support part is provided with multiple hole, and articular branches support part inner hollow is arranged, allow osseous tissue penetrate into artificial joint inside by hole, and the position of hole is set, increase the support force of articular branches support part, structure is simple, utilize the change of artificial joint structure, can be fixedly connected with bone fast, the feature that the life-span is long.
In some embodiments: hole lays respectively at 1/3rd places of articular branches support part, the bottom of 2/3rds places and articular branches support part.Thereby, it is possible to increase the support force of articular branches support part.
In some embodiments: joint rotating part is hemispherical.Thus, the rotation in utilization process is convenient to.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of artificial joint of this utility model.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1, a kind of artificial joint, comprise joint rotating part 1, the joint connecting portion 3 of articular branches support part 2 and connection joint rotating part 1 and articular branches support part 2, be spirally connected with joint connecting portion 3 top bottom joint rotating part 1 specifically, the top of articular branches support part 2 and the bottom of joint connecting portion 3 are spirally connected.Joint rotating part 1, in hemispherical, thus, is convenient to the rotation in utilization process.Articular branches support part 2 is one-body molded near the side of upper end protuberance 21, can increase the coverage rate with skeleton thus, thus eliminate the effect of bone cement.Articular branches support part 2 offers multiple hole 22, and articular branches support part 2 inner hollow is arranged, and thus, allows osseous tissue penetrate into artificial joint inside by hole.
In the present embodiment, the quantity of hole 22 is three, and specifically, hole 22 lays respectively at 1/3rd places of articular branches support part 2, the bottom of 2/3rds places and articular branches support part 2.Thereby, it is possible to increase the support force of articular branches support part.
In sum, this utility model is provided with projecting member by articular branches support part upper side, increase the coverage rate with skeleton, thus eliminate the effect of bone cement, in addition articular branches support part is provided with multiple hole, and articular branches support part inner hollow is arranged, osseous tissue is allowed to penetrate into artificial joint inside by hole, and the position of hole is set, increase the support force of articular branches support part, structure is simple, utilizes the change of artificial joint structure, can be fixedly connected with bone fast, the feature that the life-span is long.
The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, under the prerequisite not departing from this utility model creation design; can also make some similar distortion and improvement, these also should be considered as within protection domain of the present utility model.
