Description

Periprosthetic plate and fixed structure thereof
Technical field
The present invention relates to the technical field of orthopaedics implant, a kind of Periprosthetic for fractured near end of thighbone Plate and fixed structure thereof.
Background technology
Skeleton is likely to be due to wound or other reasons causes fracture, needs timely, correct to injured after fracture Skeleton reset and fix.
Blade plate is a kind of skeletal fixation apparatus conventional in surgery fracture operation.Neck of femur fracture is with near end of thighbone bone Folding needs replacement joint handle prosthese to use plate fixation near end of thighbone simultaneously.
Tradition blade plate of the prior art cannot guarantee that fixing screw can avoid joint handle completely when screwing in fixing Prosthese, if prosthese do not avoided by fixing screw, the most easily makes the position of fracture accurately to be fixed, makes operation to enter OK, operative failure is ultimately resulted in.Though fixing screw in some cases can avoid prosthese, but easily femur being penetrated, causing fixing The head exposure of screw, outside bone, affects operative effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Periprosthetic plate for fractured near end of thighbone and fixes Structure.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
The Periprosthetic plate of the present invention, including body, one end of body arranges arc-shaped head, arranges screw hole on body, The both sides distribution through wires hole in body front, through wires hole runs through body, and arranges the Wire channel in building of corresponding each through wires hole at the body back side.
The present invention can also use techniques below measure:
Arranging screw hole on described arc-shaped head, on body, distribution arranges double screw hole.
The fixed structure of the Periprosthetic plate of the present invention, including: Periprosthetic plate, fixing screw, buckle and titanium cable;Wherein Fixing screw is by passing Periprosthetic plate in the screw hole in front on body and arc-shaped head;Buckle includes clamping section and connection Portion, two clamping sections are separately positioned on the two ends of connecting portion, and body is clamped and is arranged between clamping section, and the inwall of connecting portion is with false Around body, match in the body front of plate, and clamping section, every side includes again two clamp arms, leaves space between two clamp arms of homonymy, On the top of clamp arm, fixed projection is set;The two ends of titanium cable are worn from the difference arranged by the body back side of Periprosthetic plate respectively Wire casing penetrates, and fixing via connecting in side, body front after through wires hole respectively.
The groove consistent with connecting portion setting direction is set on the outer wall of the connecting portion of described buckle.
The fixed projection that described clamp arm top is arranged is positioned at the outside of clamp arm.
The present invention has the advantage that with good effect:
The Periprosthetic plate of the present invention arranges double screw hole, through wires hole and Wire channel in building, and the fixed structure of Periprosthetic plate Include fixing screw, buckle and titanium cable, in several ways Periprosthetic plate is fixed with skeleton, can be according to human bone Bone difference, selects the fixed Combination between Periprosthetic plate and femoral bone flexibly, has both made fixing screw avoid joint handle prosthese, Prevent Periprosthetic plate from interfering with prosthese, also ensure that and the femur of fracture is stably fixed by this Periprosthetic plate, thus Alleviate the misery of patient, improve success rate of operation and can significantly shorten the convalescence of patient.In Clinical practice, the present invention Compare like product, can be the most fixing, and facilitates clinical manipulation.

Detailed description of the invention
Below by way of the drawings and specific embodiments, technical scheme is described in detail.
As shown in Figure 1 to Figure 3, the Periprosthetic plate 20 of the present invention, including body 1, one end of body arranges arc-shaped head 2, arc-shaped head matches with injury of the bone position, and in order to improve the laminating degree of Periprosthetic plate and injury of the bone position, this arc-shaped head is The arc of gradual change;Arranging screw hole 3 on body, be distributed through wires hole 4 in the both sides in body front, through wires hole runs through body, and The Wire channel in building 5 of corresponding each through wires hole is set at the body back side, in order to rise fixation titanium cable from the body back side via threading Groove and through wires hole and pass from body front, improve the work efficiency in operation.
Arranging screw hole on arc-shaped head, on body, distribution arranges double screw hole, fixing as penetrating of fixing screw Position, should be selected to avoid joint handle prosthese and will not pass the screw hole of skeleton and use in actual application.
As shown in Fig. 4 to Fig. 5, the fixed structure of the Periprosthetic plate of the present invention, including: Periprosthetic plate 20, fixing spiral shell Nail (not shown), buckle 6 and titanium cable 7;Wherein fix screw by the screw hole in front on body and arc-shaped head passes prosthese Around plate, is directly fixed Periprosthetic plate with femur 10 by fixing screw, should avoid fixing screw and pass in fixation procedure Interfere between joint handle prosthese 11, unavoidably then should choose other fixed form as interfered;Buckle 6 is formed in one, bag Including clamping section 6a and connecting portion 6b, two clamping sections are separately positioned on the two ends of connecting portion, body be clamped be arranged on clamping section it Between, the inwall of connecting portion matches with the body front of Periprosthetic plate, and clamping section, every side includes again two clamp arms 8, homonymy Two clamp arms between leave space, fixed projection 9 is set on the top of clamp arm, when clamp arm and femur fix, prosthese week Coaming plate is then stuck between buckle and femoral bone securely, thus is fixed with femur by Periprosthetic plate by buckle;If Run into multiple fracture or joint handle prosthese cause the situations such as femur spalling in installation process, then use titanium cable 7 by femur with The binding of Periprosthetic plate is fixing, and the two ends of titanium cable are worn respectively from the different Wire channel in building arranged by the body back side of Periprosthetic plate Enter, and fixing via connecting in side, body front after through wires hole respectively, Periprosthetic plate and femur is the most besieged is fixed on In titanium cable.
The groove 12 consistent with connecting portion setting direction is set on the outer wall of the connecting portion of buckle, can be increased by groove Buckle is to the fixing intensity between Periprosthetic plate and femur, thus improves Periprosthetic plate stability in use.
The fixed projection that clamp arm top is arranged is positioned at the outside of clamp arm, blocks femur by fixed projection, to improve The fastness that buckle is fixing.
The Periprosthetic plate of the present invention can take fixing screw to make with buckle combination according to the difference of patients with fractures's situation With, fixing screw is applied in combination with titanium cable, it is possible to realize fixing screw, buckle is applied in combination with titanium cable, has compound mode various Feature flexible and applied widely.
The above, be only presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, though So the present invention is open as above with preferred embodiment, but, it is not limited to the present invention, any technology people being familiar with this specialty Member, in the range of without departing from technical solution of the present invention, can utilize the technology contents of announcement make a little change or modify a certainly, Becoming the Equivalent embodiments of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technology according to the present invention is real Any simple modification, equivalent variations and the modification that confrontation above example is made, belongs in the range of technical solution of the present invention.
