Abstract
A single-condylus prosthesis relates to medical instruments, comprises a shinbone support, a shinbone cushion and a femur condylus, and is characterized in that three or more fixing columns not in the same straight line are arranged on the lower side surface of a support board of the shinbone support; the fixing columns are arranged on the inner sides of the femur condylus; positioning nails are arranged around the fixing columns on the inner sides of the femur condylus; an anti-rotation rib which has a rectangular cross section and is parallel to the fixing columns for the femur condylus is arranged on the inner sidewall of the femur condylus. When the single-condylus prosthesis is used, the shinbone support is fixedly connected with a shinbone via the fixing columns on the lower side surface of the support board, the femur condylus is connected with the a femur via the fixing columns on the inner side, the positioning nails around the fixing columns and the anti-rotation rib, the shinbone support and the femur condylus are well positioned and are unlikely to rotate. The single-condylus prosthesis is simple in structure, firm in connection and low in overhaul frequency.
Description
Technical field
The present invention relates to medical apparatus and instruments, say in detail it is good, the not voluble single condyle prosthese of a kind of tibia support and condyle of femur locating effect.
Background technology
The features such as we know, knee joint single condyle displacement is few owing to having excision sclerotin, implants few foreign, and operating time is short, be convenient to overhaul, as a kind of Wicresoft joint replacement surgery by more and more by patient and doctor are accepted.The single condyle prosthese using in current single condyle replacement comprises tibia support, tibia pad and condyle of femur, and tibia support is to be provided with the L-shaped supporting plate of cross section, and it is fixing stupefied that supporting plate downside is provided with strip.Tibia pad be symmetrical tetragon, can be free to slide be located at tibia support upper side; Condyle of femur is the prominent circular arc matching of condyle with femur, and circular arc condyle of femur middle inside is provided with the fixed leg being connected with femur, and tibia pad upper side is provided with the arc chute matching with condyle of femur, and what condyle of femur can be free to slide is located in arc chute.The tibia support of existing this single condyle prosthese and condyle of femur locating effect are poor, and after implant into body, tibia support and condyle of femur easily rotate, and overhaul frequency high.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of tibia support and condyle of femur locating effect good, with bone stable connection, difficult rotation, overhaul single condyle prosthese that frequency is low.
The present invention solves the technical scheme that above-mentioned the deficiencies in the prior art adopt:
A kind of single condyle prosthese, comprise tibia support, tibia pad and condyle of femur, the supporting plate downside that it is characterized in that tibia support is provided with at least three not fixed legs on same straight line, condyle of femur inner side is provided with fixed leg, Gu the fixed column surrounding of condyle of femur inner side is provided with locating pin, the sidewall of condyle of femur inner side is provided with the anti-rotation rib parallel with condyle of femur fixed leg, cross section is rectangular.
The supporting plate downside of the tibia support described in the present invention is provided with three fixed legs, on three fixed leg downsides that are distributed in tibia support supporting plate triangular in shape.Fixed leg locating effect the best of distribution triangular in shape.
Inside the condyle of femur of the fixed leg surrounding described in the present invention, rectangular array has four locating pins.Four locating pins can strengthen that the condyle of condyle of femur and femur is prominent to be firmly connected, avoid after use, occurring relative motion for a long time.
The present invention in use, tibia support is fixedly connected with tibia through many fixed legs of supporting plate downside, condyle of femur is connected with femur with anti-rotation rib through the fixed leg of its inner side, the locating pin of fixed leg surrounding, good, the difficult rotation of locating effect of tibia support and condyle of femur.The present invention is simple in structure, be connected firmly, and overhauls frequency low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the perspective view of condyle of femur in the present invention.
The perspective view of tibia support in Fig. 3 the present invention.
The structural representation that in Fig. 4 the present invention, tibia pad matches with tibia support.
Detailed description of the invention
Single condyle prosthese as shown in Figure 1, 2, 3, comprise tibia support 5, tibia pad 6 and condyle of femur 3, the supporting plate cross section of tibia support 5 is L-shaped, what tibia pad 6 can be free to slide is located at tibia support 5 upper sides, condyle of femur 3 is the prominent circular arc matching of condyle with femur, and tibia pad 6 upper sides are provided with the arc chute matching with condyle of femur, and what condyle of femur 3 can be free to slide is located in arc chute, said structure is same as the prior art, repeats no more.The supporting plate downside that the invention is characterized in tibia support 5 is provided with at least three not fixed legs 7 on same straight line, as can be seen from Figure 3, the supporting plate downside of tibia support is provided with three fixed legs 7, on three fixed leg 7 downsides that are distributed in tibia support supporting plate triangular in shape, fixed leg locating effect the best of distribution triangular in shape.Condyle of femur 3 middle inside are provided with fixed leg 2, fixed leg 2 surroundings of condyle of femur inner side are provided with locating pin 1, from Fig. 1, Fig. 2, can find out, the rectangular array of fixed leg 2 surrounding of condyle of femur inner side has four locating pins 1, when use, four locating pins are dashed forward and are connected with the condyle of femur, can strengthen condyle of femur and dash forward and be firmly connected with the condyle of femur, avoid occurring relative motion after long-time use.The sidewall of condyle of femur inner side is provided with the anti-rotation rib 4 parallel with condyle of femur fixed leg, cross section is rectangular, and the anti-rotation ability of the anti-rotation rib 4 of rectangle is strong.
In use, tibia support is fixedly connected with tibia through many fixed legs of supporting plate downside in the present invention, and condyle of femur matches and is connected with femur with anti-rotation rib through the fixed leg of its middle inside, good, the difficult rotation of tibia support and condyle of femur locating effect; Further connect location through the locating pin of fixed leg surrounding again, effectively reduce the frequency of overhauling of single condyle prosthese.Locating effect of the present invention is good, with bone stable connection, be difficult for rotation, overhauls frequency low.
