Abstract
The utility model discloses a femoral condyle osteotome. A side plate and a bottom plate construct an osteotome body; the side plate is arranged at one end of the bottom plate, and extends towards the upper side of the bottom plate; the side plate is provided with a transverse groove and blocking bars for guiding and positioning an osteotome saw blade; the side plate is provided with side plate arc-shaped grooves; the bottom plate is provided with two oblique knife grooves; an intercondylar bone drill guide hole is formed in the middle position of the bottom plate; and the side plate and the bottom plate are provided with a plurality of guide holes for fixing guide pins at the same time. Knee joint intercondylar osteotomy and forward and backward oblique osteotomy operation of a femoral condyle are integrated on one machine, and osteotomy is completed through one-time positioning and installation, so that an osteotomy face incision is effectively prevented from being deviated, and perfect gap-free matching of a femoral condyle implanted prosthesis and a femur head left after osteotomy is better realized. Moreover, an apparatus machining process is simplified, can be completed by adopting the currently popular procedures such as linear cutting, electric spark, numerical control milling and the like, and is easy to implement in the capability range of the current machining equipment in China. Due to the adoption of the femoral condyle osteotome, machining work hour and materials are saved, and the cost is reduced.
Description
Technical field
This utility model relates to the technical field of bone surgery set, is a kind of with the condyle of femur osteotomy device that front and back diagonal osteotomy operation is integrated mutually with condyle of femur of osteotomy between the knee joint condyle specifically.
Background technology
Fig. 1 is the structural representation of multiaspect osteotomy plate in prior art; Fig. 2 is the structural representation of osteotomy guider between condyle in prior art.
as depicted in figs. 1 and 2, at present clinically for deformity of knee, condyle of femur osteotomy apparatus used in the knee prosthesis replacement operation that damage is carried out, the multiaspect osteotomy plate 5 that is divided into condyle of femur front and back craspedodrome diagonal osteotomy, have another name called four unification osteotomy plates, and osteotomy guider 6 between the condyle of femur condyle, a kind of apparatus generally first is installed in operation, change again another apparatus after completing a part of osteotomy, carry out the osteotomy operation of a part in addition, this causes having the osteotomy resetting in operation, can't guarantee that lateral femoral condyle prosthesis coordinates with the gapless of former distal femur, therefore existing apparatus exists disadvantage and hidden danger in clinical use.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of with the condyle of femur osteotomy device that front and back diagonal osteotomy operation is integrated mutually with condyle of femur of osteotomy between the knee joint condyle.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Condyle of femur osteotomy device of the present utility model, side plate and base plate consist of the osteotomy device body, and side plate is arranged on an end of base plate and extends above base plate; Translot and the blend stop of guide-localization osteotomy saw blade are set on side plate; The side plate arcuate groove is set on side plate, and two oblique cutter grooves are set on base plate; The base plate medium position arranges bone drill pilot hole between condyle; The pilot hole of a plurality of fixation guide pins is set on side plate and base plate simultaneously.
This utility model can also adopt following technical measures:
The insertion trend of the pilot hole of described fixation guide pin is set to different angles.
Advantage and the good effect that the utlity model has are:
In condyle of femur osteotomy device of the present utility model, diagonal osteotomy operation before and after osteotomy and condyle of femur between the knee joint condyle is integrated in an apparatus, locate by once mounting in operation and complete osteotomy, effectively prevent osteotomy surface section deflection, realized that better the femoral head after condyle of femur implanting prosthetic and osteotomy are processed forms perfect gapless cooperation, reach and reduce wound, saving operation and postoperative rehabilitation time, recover the ideal effect of knee joint normal operation function.。Simplified in addition the apparatus processing technique, adopted the popular at present operations such as line cutting, electric spark and numerical control mill just can complete, be not difficult to realize in domestic existing machining equipment limit of power at present.Save machining period and materials, reduced cost.
Description of drawings
Fig. 1 is the structural representation of multiaspect osteotomy plate in prior art;
Fig. 2 is the structural representation of osteotomy guider between condyle in prior art;
Fig. 3 is the structural representation of condyle of femur osteotomy device of the present utility model.
The specific embodiment
Referring to drawings and Examples, this utility model is described in detail.
Fig. 3 is the structural representation of condyle of femur osteotomy device of the present utility model.
As shown in Figure 3, condyle of femur osteotomy device of the present utility model, side plate and base plate consist of the osteotomy device body, and side plate is arranged on an end of base plate and extends above base plate; Translot and the blend stop 1 of guide-localization osteotomy saw blade are set on side plate; Side plate arcuate groove 2 is set on side plate, and two oblique cutter groove 2b are set on base plate; The base plate medium position arranges bone drill pilot hole 3 between condyle; The pilot hole 4 of a plurality of fixation guide pins is set on side plate and base plate simultaneously.
Side plate is used for osteotomy between condyle, and translot and blend stop are used for inserting the osteotomy saw blade, play the guide-localization effect; Oblique cutter groove on base plate is for diagonal osteotomy before and after condyle of femur, and the side plate arcuate groove is used for preventing osteotomy saw blade collision side plate; Between condyle, the bone drill pilot hole is used for the front boring location of guide pin insertion of lateral femoral condyle prosthesis; Reasonably pilot hole and insertion angle design, make the apparatus in operation lay more firm
The insertion trend of the pilot hole of fixation guide pin is set to different angles.
In condyle of femur osteotomy device of the present utility model, diagonal osteotomy operation before and after osteotomy and condyle of femur between the knee joint condyle is integrated in an apparatus, locate by once mounting in operation and complete osteotomy, effectively prevent osteotomy surface section deflection, realized that better the femoral head after condyle of femur implanting prosthetic and osteotomy are processed forms perfect gapless cooperation, reach and reduce wound, saving operation and postoperative rehabilitation time, recover the ideal effect of knee joint normal operation function.。Simplified in addition the apparatus processing technique, adopted the popular at present operations such as line cutting, electric spark and numerical control mill just can complete, be not difficult to realize in domestic existing machining equipment limit of power at present.Save machining period and materials, reduced cost.
the above, it is only preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, although this utility model with preferred embodiment openly as above, yet, be not to limit this utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, certainly can utilize the technology contents of announcement to make a little change or modification, become the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
