Multifunctional traction and bone fixation device

A multifunctional traction and bone fixation device, comprising:

• two traction clamping plates,
• a traction nail,
• a positioning and pressurizing screw,
• a traction handle screw,
• a nail protection screw,
• an auxiliary fixation pin hole,
• a unidirectional auxiliary fixation pin holder,
• an integral unidirectional auxiliary fixation pin holder,
• a lateral auxiliary fixation pin holder,
• a bidirectional auxiliary fixation pin holder,
• an integral bidirectional auxiliary fixation pin holder,
• a foot bottom fixation pin holder, and
• an auxiliary fixation pin;
• wherein a front end of a body of each traction clamping plate defines a plurality of traction nail mounting holes, a middle portion of the body of each traction clamping plate defines a plurality of second mounting holes and a plurality of screw holes, a rear end of the body of each traction clamping plate defines a third mounting hole, a top of each traction clamping plate is bent for 90 degrees and defines a top screw hole, one of the plurality of second mounting holes defined in the middle portion of one of the two traction clamping plates is connected to one of the plurality of second mounting holes defined in the middle portion of an other one of the two traction clamping plates by the positioning and pressurizing screw,
• the third mounting hole defined in the rear end of the one of the two traction clamping plates is connected to the third mounting hole defined in the rear end of the other one of the two traction clamping plates by the traction handle screw, a reinforcement nut is arranged on a screw pattern of each of two heads of the positioning and pressurizing screw and each of two heads of the traction handle screw, the reinforcement nut is arranged at each of an inside and an outside of one of the two traction clamping plate for adjustment and fixation;
• the traction nail is connected to each traction clamping plate through the plurality of traction nail mounting holes, the reinforcement nut is arranged on a screw pattern of the traction nail and is arranged at each of an inside and an outside of each traction clamping plate for adjustment and fixation;
• the nail protection screw is arranged inside the top screw hole, a head of the traction nail, which is arranged at a front end of one of the two traction clamping plates, and a head of the traction nail, which is arranged at a front end of the other one of the two traction clamping plates, are injected in opposite directions into a lower portion of a fractured site to determine a fixation position, the rear end of each traction clamping plate extend along a thigh direction to be weighted-pulled through the traction handle screw;
• the middle portion of the body of each traction clamping plate is arranged with the unidirectional auxiliary fixation pin holder and the integral unidirectional auxiliary fixation pin holder, a fixation pin is arranged inside a first threading hole defined in each of a front end of the unidirectional auxiliary fixation pin holder and a front end of the integral unidirectional auxiliary fixation pin holder, the fixation pin disposed at a middle-front portion of each traction clamping plate abuts against a fractured bone to achieve auxiliary fixation;
• the lateral auxiliary fixation pin holder is disposed at a middle-rear portion of each traction clamping plate, the fixation pin is arranged inside a second threading hole defined in a front end of the lateral auxiliary fixation pin holder, a head of the lateral auxiliary fixation pin disposed at the middle-rear portion of each traction clamping plate abuts against a fractured bone to achieve auxiliary fixation;
• the bidirectional auxiliary fixation pin holder and the integral bidirectional auxiliary fixation pin holder are arranged on each of two sides of the middle-front portion of each traction clamping plate, the fixation pin is arranged inside a third threading hole defined in each of a front end of the bidirectional auxiliary fixation pin holder and a front end of the integral bidirectional auxiliary fixation pin holder, a head of the traction nail, which is arranged at the front end of one of the two traction clamping plates, and heads of fixation pins, which are arranged at two sides of the middle-front portion of each traction clamping plate, abut against two sites of the fractured bone to achieve auxiliary fixation.
