Description

Thighbone condyle test model

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a thighbone condyle examination mould.

Background

In the artificial knee joint replacement, after the operator processes the osteotomy and the bone shaping, the operator needs to install a prosthesis trial mold to confirm the suitability of the operation process, thereby ensuring the stability of the prosthesis after the installation of the real prosthesis and the recovery of the joint movement of the patient after the operation. In the prior art, the knee joint femoral condyle prosthesis is tested by using a metal material (generally stainless steel) and is of a full solid structure. When the metal solid femoral condyle prosthesis is used, the difficulties of transportation and preoperative sterilization are increased due to the weight, and meanwhile, the problems of deformation and abrasion are easily caused after long-term repeated use, and the preparation is complicated, so that the mutual conversion of PS and CR is inconvenient to realize.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a simple structure is provided, and the preparation is convenient, and durable and be convenient for realize by the PS type to the conversion of CR type a thighbone condyle examination mould.

The utility model discloses a realize through following technical scheme:

the utility model provides a thighbone condyle examination mould, its includes the examination mould body with thighbone condyle prosthesis shape looks adaptation, the examination mould body is seted up tibial plateau pad stand hole of stepping down by PAEK material integrated into one piece at the middle part of examination mould body, and fixed column mounting hole has been seted up respectively to the inside and outside both sides in tibial plateau pad stand hole of stepping down, and a side middle part of examination mould body is equipped with the interval and is divided into two parts with the side of examination mould body at the corresponding position in tibial plateau pad stand hole of stepping down, interval department fixed mounting has the backstop, is equipped with a plurality of reinforcement grooves on the internal surface of examination mould body.

Optimally, the back stop and the test die body are integrally formed.

Optimized, the rear baffle is fixedly connected with the test mold body through a connecting piece.

Furthermore, the inner surfaces of the inner end and the outer end of the test mould body are provided with clamping grooves.

Optimally, the tibial plateau pad stand column abdicating hole is a rectangular hole.

Preferably, the fixing column mounting holes are round holes.

Preferably, the reinforcing groove is a rectangular groove.

The beneficial effects of the utility model

The utility model provides a pair of thighbone condyle examination mould has following advantage:

1. the structure is simple, and the manufacture is convenient;

2. the weight is light, the deformation and the abrasion are not easy to occur, and the service life is long;

3. the conversion from PS to CR is facilitated.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure, 01, a test die body, 02, a shin bone platform pad upright post abdicating hole, 03, a fixed post mounting hole, 04, a clamping groove, 05, a reinforcing groove and 06, a rear stop are arranged.

Detailed Description

The utility model provides a thighbone condyle examination mould, its includes examination mould body 1 with thighbone condyle prosthesis shape looks adaptation, examination mould body is seted up shin bone platform pad stand hole 2 of stepping down by PAEK material integrated into one piece at the middle part of examination mould body, and fixed column mounting hole 3 has been seted up respectively to the inside and outside both sides in shin bone platform pad stand hole of stepping down, and a side middle part of examination mould body is equipped with the interval and is divided into two parts with the side of examination mould body at the corresponding position of shin bone platform pad stand hole of stepping down, interval department fixed mounting has backstop 6, is equipped with a plurality of reinforcement grooves 5 on the internal surface of examination mould body.

Optimized, backstop and examination mould body integrated into one piece, convenient processing, when needs to get rid of to the CR type, as long as with the backstop saw remove or adopt other modes get rid of can, be convenient for by the conversion of PS type to the CR type.

Optimized, keep off and try to pass through connecting piece fixed connection between the mould body, when needs are to CR type conversion, as long as demolish connecting piece and backstop and can realize by the conversion of PS type to CR type, easy dismounting, labour saving and time saving.

Furthermore, the inner surfaces of the inner end and the outer end of the test die body are provided with clamping grooves 4, so that the test die body can be conveniently clamped by a tool.

Optimally, the tibial plateau pad stand column abdicating hole is a rectangular hole, is matched with the tibial plateau pad stand column in a collision way, and is prevented from rotating randomly.

Optimally, the fixing column mounting holes are round holes, are matched with the shapes of the fixing columns, and are convenient to process.

Optimized, the reinforcing groove is the rectangular channel, is favorable to improving the intensity of examination mould body, prevents its deformation.

The utility model provides a pair of thighbone condyle examination mould, the shin bone platform pad stand hole of stepping down at examination mould body middle part, the convenience is placed examination mould body and is stacked up at the shin bone platform, punches on the bone through these two holes during formal false body of two fixed column mounting holes easy to assemble for the installation of fixed column.

Because its examination mould body is by PAEK material integrated into one piece, simple structure, the preparation is convenient to the quality is light, the transportation of being convenient for, simultaneously because PAEK material hardness is high, non-deformable, simultaneously in the design, be equipped with a plurality of strengthening grooves on the internal surface, further realize inside subtract heavy, strengthening groove and make the inside thickness of examination mould change evenly, prevent deformation, increased the durability of examination mould.

Simultaneously because a side middle part of examination mould body is equipped with the interval and will try the side of mould body and divide into two parts with tibial plateau pad stand hole corresponding position of stepping down, interval department fixed mounting has the backstop, this designs for the PS type, the effect of backstop prevents that tibial plateau pad stand from stepping down hole department roll-off from tibial plateau pad stand, if need CR type try the mould, as long as with the backstop remove can, high durability and convenient operation, save time and labor, can easily realize the conversion of PS type to CR type.

To sum up, use the utility model provides a pair of thighbone condyle examination mould, simple structure, the preparation is convenient, and durable and be convenient for realize by the conversion of PS type to CR type.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
