Abstract
The utility model relates to an artificial joint capable of being firmly connected. The artificial joint capable of being firmly connected comprises a helmet-shaped ball head (1) and a joint handle (3), wherein a plurality of protruding parts (2) are evenly arranged on the handle body of the joint handle (3), the joint handle (3) is a multi-hole manufactured piece, and the joint handle (3) is connected with the helmet-shaped ball head (1) in a threaded mode. The artificial joint capable of being firmly connected has the advantages of being simple in structure, rapidly achieving permanent connection with a bone and the like, the biocompatibility of the artificial joint is greatly improved, the service life of the artificial joint is greatly prolonged, and the implanting comfort of the artificial joint is greatly improved.
Description
Technical field
This utility model relates to the joint prosthesis field, is specifically related to a kind of artificial joint that has good biocompatibility and can firmly connect.
Background technology
The joint is the hinge of human motion, since wound or pathological changes, possibility " scrapping ", and at this moment the doctor often will " scrap " arthrectomy, change artificial joint.Human synovial is the great-hearted organ of tool, and the artificial joint of changing all is unvital prosthese.
Artificial joint replacement is the articular surface excision with wear-out failure, and implantable artificial joint as the dress facing makes it recover normal level and smooth articular surface.After joint replacement is finished in the prior art, often adopt bone cement that bone and artificial joint are fixed, but bone cement can cause the medullary cavity inner high voltage when filling once in a while, causes the fat drop intravasation, causes thromboembolism.In addition, it is different from skeleton after all, and the time is excessively of a specified duration, and artificial joint still may become flexible, and can not realize preferably firm connection.And in the prior art, select and the structure of artificial joint arranges the certain defective of upper existence, repulsion can occur with tissue after causing that artificial joint is long-time and using, and biocompatibility is relatively poor and affect its service life.
The utility model content
The purpose of this utility model is to provide a kind of artificial joint that can firmly connect, and this artificial joint is simple in structure, can be fixedly connected with bone fast, has good biocompatibility concurrently, has prolonged service life.
The purpose of this utility model is achieved in that
A kind of artificial joint that can firmly connect, it comprises helmet shape bulb and joint handle, evenly is provided with several projecting member on the described joint handle handle body, with the coverage rate of increase with skeleton, and realizes firm the connection; Described joint handle is the porous product; Described joint handle and described helmet shape bulb adopt and are threaded, and make up with convenient the fractionation.
Above-mentioned joint handle preferably adopts the porous tantalum product.Find that through studying for a long period of time the porous tantalum product in the biocompatibility that has greatly improved joint handle, has also well satisfied its mechanical property, greatly improved its service life and implanted comfort level.Above-mentioned porous tantalum product can adopt the preparations such as foam dipping method, die pressing, and its porosity is 60 ~ 70%.
Further, above-mentioned helmet shape bulb semicircular in shape is convenient to the rotation in the utilization process.
The utlity model has following beneficial effect:
This utility model evenly is provided with several projecting member on joint handle handle body, increased the coverage rate with skeleton, and realizes firm the connection, thus the effect of also having saved bone cement, and the connection side by screw thread split combination.It has simple in structure, has realized rapidly and the characteristics such as bone is fixedly connected with.Be set to the porous tantalum product by joint handle again, greatly improved the biocompatibility of this artificial joint, also well satisfied simultaneously its mechanical property, greatly improved the service life of this artificial joint and implanted comfort level.
Description of drawings
Fig. 1 is the structural representation of the artificial joint that can firmly connect described in this utility model embodiment 1.
The specific embodiment
Be this utility model preferred embodiment below, and be not be used to limiting protection domain of the present utility model.
Embodiment 1
As shown in Figure 1: a kind of artificial joint that can firmly connect, it comprises helmet shape bulb 1 and joint handle 3, joint handle 3 handle bodies evenly are provided with several projecting member 2 all around, with the coverage rate of increase with skeleton, and realize firm connection; Joint handle 3 is the porous tantalum product, and its porosity is 60 ~ 70%; Joint handle 3 and helmet shape bulb 1 adopt and are threaded, and make up with convenient the fractionation; Helmet shape bulb 1 semicircular in shape is convenient to the rotation in the utilization process.
Owing to being provided with projecting member 2 in the same side, joint handle 3 top, increased the coverage rate with skeleton, thus the effect of having saved bone cement; Have simple in structurely, utilize the change of artificial joint structure, realized rapidly and the characteristics such as bone is fixedly connected with.
Claims (3)
1. artificial joint that can firmly connect, it comprises helmet shape bulb (1) and joint handle (3), evenly is provided with several projecting member (2) on described joint handle (3) the handle body; Described joint handle (3) is the porous product; Described joint handle (3) and described helmet shape bulb (1) adopt and are threaded.
2. the artificial joint that can firmly connect according to claim 1 is characterized in that: described joint handle (3), adopt the porous tantalum product, and its porosity is 60 ~ 70%.
3. the artificial joint that can firmly connect according to claim 1 and 2 is characterized in that: described helmet shape bulb (1) semicircular in shape.
