Abstract
The invention provides a kind of Fracture of femur pulling off reset device, belong to a kind of medical apparatus and instruments, it has the first extension rod and the second extension rod, the two ends of two bars link together respectively by the first pipe pipe clamp and the second pipe pipe clamp, the middle part of two bars has the first extender and the second extender respectively, one end of first extension rod is fixed with steinman pin sleeve pipe by the 3rd pipe pipe clamp, steinman pin is had in steinman pin sleeve pipe, one end of second extension rod is fixed with semi-ring bar by the 4th pipe pipe clamp, first Ke Shi pin is fixed on semi-ring bar by the first tube needle clamp and the second tube needle clamp, the second Ke Shi pin vertical with the first Ke Shi pin is fixed on semi-ring bar by the 3rd tube needle clamp.This Fracture of femur pulling off reset device, when carrying out closed reduction, magnetic navigation intramedullary needle treatment fracture of shaft of femur can be combined, not only solve a difficult problem for closed reduction, considerably increase the motility operated in art, and avoid the complication caused because application extension table resets.
Description
Technical field
The invention provides a kind of medical apparatus and instruments, especially a kind of orthopaedics apparatus.
Background technology
Femur fixing interlocking intramedullary nail internal fixtion is the goldstandard for the treatment of fracture of shaft of femur, but although X-ray examination is quite universal in art, Fracture of femur closed reduction technology wherein still exists certain difficulty at present.In addition, application X-ray examination too much in art is also that most surgeon institute is unacceptable, and this just causes many orthopedists still to adopt open reduction intramedullary needle inner fixation treatment of femoral shaft fractures at present.Adopting extension table to reset is the traditional method that current most orthopedist adopts in fracture of shaft of femur art, but the reason due to extension table special posture limits the motility operated in art, operate particularly difficulty in particularly healthy and strong or fat for build patient's art, and easily to cause in art the complication such as fracture of femoral neck.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of Fracture of femur pulling off reset device, to improve its result of use.
The present invention realizes like this, Fracture of femur pulling off reset device, it has the first extension rod and the second extension rod, the two ends of two bars link together respectively by the first pipe pipe clamp and the second pipe pipe clamp, the middle part of two bars has the first extender and the second extender respectively, one end of first extension rod is fixed with steinman pin sleeve pipe by the 3rd pipe pipe clamp, steinman pin is had in steinman pin sleeve pipe, one end of second extension rod is fixed with semi-ring bar by the 4th pipe pipe clamp, first Ke Shi pin is fixed on semi-ring bar by the first tube needle clamp and the second tube needle clamp, the second Ke Shi pin vertical with the first Ke Shi pin is fixed on semi-ring bar by the 3rd tube needle clamp.
Adopt the Fracture of femur pulling off reset device of said structure, when carrying out closed reduction, magnetic navigation intramedullary needle treatment fracture of shaft of femur can be combined, not only solve a difficult problem for closed reduction, considerably increase the motility operated in art, and avoid the complication caused because application extension table resets.

Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing further illustrates the present invention.
As shown in drawings, the Fracture of femur pulling off reset device of the present invention, it has the first extension rod 4 and the second extension rod 6, the two ends of two bars link together respectively by the first pipe pipe clamp 5 and the second pipe pipe clamp 9, the middle part of two bars has the first extender 7 and the second extender 8 respectively, one end of first extension rod is fixed with steinman pin sleeve pipe 2 by the 3rd pipe pipe clamp 1, steinman pin 3 is had in steinman pin sleeve pipe, one end of second extension rod is fixed with semi-ring bar 12 by the 4th pipe pipe clamp 13, first Ke Shi pin 10 is fixed on semi-ring bar by the first tube needle clamp 11 and the second tube needle clamp 16, the second Ke Shi pin 15 vertical with the first Ke Shi pin is fixed on semi-ring bar by the 3rd tube needle clamp 14.
During use, associating magnetic navigation under operating procedure as follows: 1, pierce steinman pin 3 in ilium anterior superior iliac spine position, the diameter of this pin is 4.0mm, needle angle for inwardly to go up each inclination 15 degree of angles, by steinman pin casing pipe sleeve outside steinman pin.2, inwardly pierce the first Kirschner wire 10 in external epicondyle of femur, then front partially pierces the second Kirschner wire from front upper to the back lower place in inner side on condyle of femur, each Kirschner wire semi-ring bar is coupled together formation fixed structure, the diameter of each Ke Shi pin is 3mm.3, with each pipe pipe clamp, steinman pin sleeve pipe, semi-ring bar and extension rod are linked together.4, rotate extender make extension rod lengthen thus by Fracture of femur end distraction reduction.5, insert intramedullary needle after near end of thighbone Pyriform sinus opening insertion pulp cavity guide pin, expansion marrow to fix.
First, second described extender one end is connected on one section of extension rod, the other end is linked together by another section of screw thread and extension rod.When rotating extender, another elongated segment bar threaded inserts in not threaded elongated segment bar or stretches out in this elongated segment bar, changes the entire length of extension rod.
As shown in Figure 4, each pipe pipe clamp has bolt 36, is set with pad 34 in the middle part of bolt, the both sides of pad are provided with the first pipe clamp body 32 and the second pipe clamp body 35 respectively by screw thread, two pipe clamp bodies have arcuate groove 33 respectively, and the end face of bolt has polygonal groove 31.When two pipe clamp bodies are arranged side by side, can be used for being connected and fixed between two parallel pipes or bar, when two pipe clamp bodies are vertical, can be used for being connected and fixed between two vertical pipes or bar, when being connected and fixed, in the polygonal groove of bolt, insertion tool, rotating bolt.The pipe be connected or bar are positioned at arcuate groove.The structure of tube needle clamp is similar to pipe pipe clamp, no longer describes in detail.
