Abstract

A tibia far-end lateral bone plate comprises a head portion and a lath which is positioned below the head portion. A bone-knitting screw hole is opened on the tibia far-end lateral bone plate, the lath is a torsion lath which is matched with the torsion portion of diaphysis on the tibia far-end lateral side, and the head portion takes on a fan-shaped convex cambered surface which has edge bifurcation, which is matched with the lower end external malleolus of the tibia far-end lateral side. When in use, the tibia far-end lateral bone plate of the utility model can effectively jointed with the tibia far-end lateral side.

Description

A kind of distal tibial outside blade plate

(1) technical field

This utility model relates to a kind of distal tibial outside blade plate.

(2) background technology

Existing distal tibial outside blade plate all can not fit with the distal tibial outside effectively: with reference to Fig. 1, Fig. 2, the head of trifolium-shaped blade plate is trifolium-shaped, it below the head vertical bar plate, yet the backbone of distal tibial outside has torsional part, therefore the trifolium-shaped blade plate is difficult to and effectively fit in the distal tibial outside, in addition, and when using the trifolium-shaped blade plate to connect to control distal tibial outside fracture, intermediary blade shaped plate need be amputated, operation is trouble very; The structure of the distal tibial outside blade plate of all the other versions also is made up of head and the straight board lath below the head basically, also can not effectively fit with the distal tibial outside.

(3) summary of the invention

In order to overcome the above-mentioned deficiency of existing distal tibial outside blade plate, this utility model provides a kind of and can effectively fit with the distal tibial outside, distal tibial outside blade plate simple to operate during operation.

The technical scheme in the invention for solving the technical problem is: a kind of distal tibial outside blade plate, comprise the lath that head and head are following, offer bone screw hole on this distal tibial outside blade plate, it is characterized in that: described lath for the backbone's of distal tibial outside reverse part suitable reverse lath, described head is and the suitable band of the lower end external malleolus of the distal tibial outside fan-shaped convex globoidal of fate fork on one side.

Further, the front end of described head also offers locating hole.

During use, distal tibial described in the utility model outside blade plate can effectively be fitted with the distal tibial outside.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

With reference to Fig. 3 ~ Fig. 6, a kind of distal tibial outside blade plate, comprise head 1 and the head lath 2 below 1, offer bone screw hole 3 on this distal tibial outside blade plate, described lath 2 for the backbone's 4 of distal tibial outside reverse part suitable reverse lath, described head 1 is and the suitable band of the lower end external malleolus of the distal tibial outside fan-shaped convex globoidal 6 of fate fork 5 on one side.For the ease of the location, also offer locating hole 7 at the front end of described head.This utility model is divided into left plate (as Fig. 4, shown in Figure 5) that is applicable to left lower limb and the right panel (as Fig. 5, shown in Figure 6) that is applicable to right lower limb.

This utility model in use, at first locating pin is penetrated the Primary Location that realizes blade plate in the locating hole 7, then bone screw 8 is penetrated the bone screw hole 3 on the blade plate of the distal tibial outside, distal tibial outside blade plate is fixed on the tibia by bone screw 8.

In the present embodiment, be placed with 14 bone screw hole 3 on the blade plate, but be not limited thereto, offering of bone screw hole 3 can be determined on a case-by-case basis.

Claims

1. distal tibial outside blade plate, comprise the lath that head and head are following, offer bone screw hole on this distal tibial outside blade plate, it is characterized in that: described lath for the backbone's of distal tibial outside reverse part suitable reverse lath, described head is and the suitable band of the lower end external malleolus of the distal tibial outside fan-shaped convex globoidal of fate fork on one side.

2. distal tibial as claimed in claim 1 outside blade plate, it is characterized in that: the front end of described head also offers locating hole.
