Description

Needle plate formula external fixer

One, technical field

This utility model belongs to the medical apparatus and instruments of set a broken bone, specifically a kind of external fixer of orthopaedics therapy shank fracture of tibia and fibula.

Two, background technology

The tibiofibula that is positioned at the human body calf takes place to rupture or fracture is a kind of common frdquently encountered disease that is caused by exterior injury.The treatment fixing means of clinical employing generally has external fixer behind the fracture of tibia and fibula at present, and bone traction or skin traction cooperate plintlet, plaster fixation etc.Existing external fixer such as single armed, both arms, annular, the semi-circular method of respectively wearing at least two pieces of draw points at two broken ends of fractured bone that all adopts, the weak point of existence is: because it is more to thread a needle, increased the infection probability, and easily loosening; When resetting, adopt open reduction, increased the danger of treatment.Internal fixation method has not only increased the infection probability owing to adopt open reduction and implant internal fixation apparatus, and has destroyed bone stump blood fortune, influences union of fracture, and needs second operation to take out.

Three, summary of the invention

The purpose of this utility model is in order to overcome the deficiency that above-mentioned technology exists, a kind of needle plate formula external fixer to be provided, and it is few to implant draw point, resets fixedly to be simple and easy to regulate, and makes tibiofibula treat safety and good effect.This utility model is achieved in that needle plate formula external fixer, the shank support plate 1 of horizontal positioned and foot hold 2 are fixed on the horizontal stand 3 of both sides by screw, step tread plate 13 vertically is installed in foot hold 2 outer ends, by crossing retaining wedge 17 the side prelum is installed at the middle part of support 3; Left end at support 3 is equipped with the trocar actuator by adjusting nut 6; Trocar actuator and the side prelum installed on the horizontal stand 3 of described both sides all are symmetrical arranged.

Be fixed with montant 15 on the adjusting nut 6 of trocar actuator bottom, be fixed with lateral frame 16 on the montant 15 vertical regulating blocks 7, the termination of lateral frame 16 is equipped with trocar device 8, between two trocar devices 8 pull needle 9 is installed; Be fixed with montant 18 on the retaining wedge 17 of prelum bottom, side, an end of montant 18 is fixed with the cross bar 19 of band arc card by regulating block 4;

Step tread plate

10,13 is sleeved on together by screw rod, nut 21, before and after being fixed with, vertical step tread plate 13 outsides become angle actuator 11, be respectively equipped with anglec of rotation adjustment hole 12 in the lower end of double-deck step tread plate, front and back become the screw thread montant 22 of angle actuator to be fixed on the step tread plate 13 by nut bearing 20, also by screw thread slide block 24 is installed on the montant 22 and is fixed as one with step tread plate 10, slide block 24 is installed in the chute 23.

Below shank support plate 1 and foot hold 2, supporting leg 14 is installed; Support 3 is divided into two sections, and the support of the support of shank support plate 1 side and foot hold 2 sides is installed as one by screw thread, and foot hold 2 side support plates are set with the traction adjusting rod 5 of threaded end in the hollow loop bar.

Compare with present therapeutic modality, the beneficial effects of the utility model are:

1, adopting needle plate formula external fixer treatment fracture of tibia and fibula is that advantage collection with existing plintlet and traction therapeutic is an one, pull needle in the implant into body in treatment, because of the locking pin quantity implanted few, overcome spininess and fixed the shortcoming that the formation stress shielding influences union of fracture, reduced the infection probability to greatest extent;

2, avoided open reduction in the existing Therapeutic Method, therapeutic process is safer reliable;

3, owing to earlier lower leg portion is fixed with pull needle in therapeutic process, then foot is fixed, can be carried out the trace adjustment of top to bottom, left and right, front and rear and windup-degree, the advanced perspective scanning technique of configuration can be guaranteed the degree of accuracy for the treatment of again;

4, fixed mount only is fixed on patient's shank with the lower part, does not influence kneed activity, helps the functional exercise between convalescent period behind the patient treatment.Utilize elasticity step tread plate 13 to do the fine motion that produces when function is taken exercise, form the fine motion of bone stump, impel growth of spur, union of fracture.And when the broken ends of fractured bone takes place to be shifted in fixing back, cause the conduction of bone stump mechanics to interrupt causing the muscle retraction, limb shortening, fixedly the pressure increase of bag of stretching tight of foot to foot.So in time remind patient and doctor to adjust, both made things convenient for check and treatment, can understand which kind of motion again, which kind of degree helps union of fracture or is unfavorable for union of fracture.
