Abstract

The utility model discloses a tibia back ankle locking plate which comprises a plate body. A main screw locking hole is formed in the plate body, the far end of the plate body is fixedly connected with a left side arm and a right side arm, the plate body, the left side arm and the right side arm are of an integral structure and in an inverted-T shape, a left screw locking hole is formed in the left side arm, a right screw locking hole is formed in the right side arm, the edges of the plate body, the left side arm and the right side arm are respectively provided with edge concaves, the left side arm and the right side arm are bent backwards relative to the plate body, the thickness of the left side arm and the thickness of the right side arm are respectively smaller than the thickness of the plate body, and kirschner wire fixing holes are also formed in the left side arm and the right side arm and formed in the edges of the left side arm and the right side arm. Due to the facts that the tibia back ankle locking plate is structurally suitable for tibia back ankle dissection, and edge concaves are formed in the edges of the plate, the left side arm and the right side arm, the tibia back ankle locking plate has figurability, is easy to bend and deform, and can be well attached to the tibia back ankle.

Description

Ankle lockplate after tibia

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to ankle lockplate after a kind of tibia.

Background technology

After tibia, ankle also claims the distal tibial posterior tubercle, half arc before and after the distal tibial joint is, the pollex contact surface is front shallow rear dark, therefore, when ankle joint is subject to by backward front lower impulsive force (as high falling, go downstairs, walk and stop in the urgency on downhill path and in running etc.), tibia is done front lower motion on the astragalus surface, and rear ankle is subject to the shock of astragalus and fractures.Complicated ankle joint fracture often relates to external malleolus, internal malleolus and rear ankle, and injured mechanism is complicated, and treatment requires anatomical reduction, good fixing.It is more difficult in ankle joint fracture that to reset fixing be back ankle fracture.Traditional method is treated this type of fracture and is comprised: closed reduction, Gypsum Fibrosum outward fixing, calcaneal traction, open reduction hollow nail, can absorb in nail etc. fixing, but there are the problems such as articular surface malreduction, fixing not firm, fracture redisplacement, the complication rates such as the fracture delayed union caused thus, bone does not connect, malunion, ankylosis, traumatic arthritis are high, it is poor that ankle joint function is recovered, and easily leaves over deformity.

Summary of the invention

The purpose of this utility model be to provide a kind of can make the tibia back ankle fracture stable reset and strong interior fixing tibia after the ankle lockplate.

For achieving the above object, the technical solution adopted in the utility model is:

Ankle lockplate after a kind of tibia, comprise plate body, have main screw lock hole on plate body, the plate body far-end is fixedly connected with left side arm and right arm, plate body, left side arm and right arm are structure as a whole, and plate body, left side arm and right arm form is shaped as inverted " T " font, has left screw lock hole on the arm of left side, have right screw lock hole on right arm, the edge of plate body, left side arm and right arm all offers marginal trough.

According to ankle lockplate after described tibia, it is characterized in that: described left side arm and described right arm are crooked backward with respect to described plate body; The thickness of left side arm and right arm is less than the thickness of plate body.

According to ankle lockplate after described tibia, it is characterized in that: also have the Kirschner wire fixing hole on described left side arm and described right arm, the Kirschner wire fixing hole is along the edge setting of left side arm and right arm.

Because structure of the present utility model meets ankle after tibia, dissect, plate body edge and left and right side arm edge all have marginal trough, have plasticity, and flexible distortion can be attached at after tibia on ankle preferably.According to this lockplate of the moulding attaching of classification of fracture, tighten after lock screw fixing different types tibia back ankle fracture preferably.After lock screw and the locking of screw lock hole, lock screw and lockplate are into a single integrated structure, can play the effect of inner fixed support, fixing strong, without outer fixing, can make the tibia back ankle fracture stablize and reset, and can carry out early functional exercise, and joint function recovery is good.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the left view structural representation of Fig. 1.

In accompanying drawing:

1, plate body; 2, main screw lock hole; 3, marginal trough; 4, right arm; 5, right screw lock hole; 6, Kirschner wire fixing hole; 7, left screw lock hole; 8, left side arm.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, this utility model is further described:

Ankle lockplate after a kind of tibia, as depicted in figs. 1 and 2, compriseplate body 1, have main screw lock hole 2 onplate body 1,plate body 1 far-end is fixedly connected withleft side arm 8 and right arm 4, andplate body 1,left side arm 8 and right arm 4 are structure as a whole,plate body 1,left side arm 8 and right arm 4 form is shaped as inverted " T " font, have left screw lock hole 7 on thearm 8 of left side, have right screw lock hole 5 on right arm 4, the edge ofplate body 1,left side arm 8 and right arm 4 all offers marginal trough 3.In the present embodiment,left side arm 8 and right arm 4 are crooked backward with respect toplate body 1; The thickness ofleft side arm 8 and right arm 4 is less than the thickness of plate body 1.Also have Kirschner wire fixing hole 6 onleft side arm 8 and right arm 4, Kirschner wire fixing hole 6 is along the edge setting ofleft side arm 8 and right arm 4.

Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and scope are limited; under the prerequisite that does not break away from this utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that this utility model is asked for protection, all be documented in claims.

All have the screw lock hole on left and right side arm of the present utility model, for the fixed tibial back ankle fracture.Plate body and left and right side arm edge have a plurality of marginal troughs, have plasticity, and flexible distortion is beneficial to mouldingly, can be attached at preferably after tibia on ankle.Also have the Kirschner wire fixing hole on the left and right side mural margin, be beneficial to the fixing articular surface of ankle fracture of pulverizing of Kirschner wire.

Making material selection titanium alloy of the present utility model, histocompatibility is good, firm light, fatigue resistance good.The Thickness Ratio plate body position of left and right side arm is thin, meets the topography structure.

This utility model is attached to ankle after tibia, and after tightening lock screw, the tibia back ankle fracture is multi-faceted firm fixed, and can make that the tibia back ankle fracture is stable to be resetted fixingly, and result of use is good.
