Abstract
The invention provides a femur fracture strutting reducing device, and belongs to a medical apparatus. The femur fracture strutting reducing device comprises a first extension rod and a second extension rod, the two ends of the first extension rod and the second extension rod are connected together through a first pipe clamp and a second pipe clamp respectively, a first extender and a second extender are arranged in the middles of the first extension rod and the second extension rod respectively, a Steinmann pin sleeve is fixed to one end of the first extension rod through a third pipe clamp, a Steinmann pin is arranged in the Steinmann pin sleeve, a semi-ring rod is fixed to one end of the second extension rod through a fourth pipe clamp, a first Kirschner pin is fixed to the semi-ring rod through a first tubular pin clamp and a second tubular pin clamp, and a second Kirschner pin perpendicular to the first Kirschner pin is fixed to the semi-ring rod through a third tubular pin clamp. By means of the femur fracture strutting reducing device, when closed reduction is carried out, the femur fracture strutting reducing device can be combined with a magnetic force navigation intramedullary needle to treat the femoral shaft fracture, the closed reduction aim is achieved, the operation flexibility during an operation is greatly improved, and complications caused by applying a traction table to carry out reduction are avoided.
Description
Technical field
The invention provides a kind of medical apparatus and instruments, especially a kind of orthopaedics apparatus.
Background technology
In femur fixing interlocking intramedullary nail, be fixedly the goldstandard for the treatment of fracture of shaft of femur, yet although X-ray examination is quite universal in art, still there is certain difficulty in Fracture of femur closed reduction technology wherein at present.In addition, in art, too much application X-ray examination is also that most surgeon institute is unacceptable, and this just causes many orthopedists still to adopt at present open reduction intramedullary needle inner fixation treatment of femoral shaft fractures.Adopting extension table to reset is the traditional method that current most orthopedist adopts in fracture of shaft of femur art, but because the reason of extension table special posture has limited the motility operating in art, the operation difficulty particularly in healthy and strong or fat patient's art for build particularly, and easily cause in art the complication such as fracture of femoral neck.
Summary of the invention
Technical problem to be solved by this invention is to provide 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 by the first pipe pipe clamp and the second pipe pipe clamp respectively, there are respectively the first extender and the second extender in the middle part of two bars, one end of the first extension rod is fixed with steinman pin sleeve pipe by tee pipe pipe clamp, in steinman pin sleeve pipe, there is steinman pin, one end of the second extension rod is fixed with semi-ring bar by the 4th pipe pipe clamp, the 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 bobbin folder.
Adopt the Fracture of femur pulling off reset device of said structure, when carrying out closed reduction, can combine magnetic navigation intramedullary needle treatment fracture of shaft of femur, not only solved a difficult problem for closed reduction, greatly increase the motility operating in art, and avoided the complication that resets and to cause because of application extension table.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structure of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 has represented the connected mode of the first extension rod and steinman pin sleeve pipe.
Fig. 4 has represented the structure of pipe pipe clamp.
The specific embodiment
The embodiment providing below in conjunction with accompanying drawing further illustrates the present invention.
As shown in drawings, the present invention's Fracture of femur pulling off reset device, it has the first extension rod 4 and the second extension rod 6, the two ends of two bars link together by the first pipe pipe clamp 5 and the second pipe pipe clamp 9 respectively, there are respectively the first extender 7 and the second extender 8 in the middle part of two bars, one end of the first extension rod is fixed with steinman pin sleeve pipe 2 by tee pipe pipe clamp 1, in steinman pin sleeve pipe, there is steinman pin 3, one end of the second extension rod is fixed with semi-ring bar 12 by the 4th pipe pipe clamp 13, the 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, the operating procedure in associating under magnetic navigation is as follows: 1, in ilium anterior superior iliac spine position, pierce steinman pin 3, the diameter of this pin is 4.0mm, and needle angle is the 15 degree angles that inwardly upwards respectively tilt, by steinman pin casing pipe sleeve outside steinman pin.2, in external epicondyle of femur, inwardly pierce the first Kirschner wire 10, then the place ahead partially from front upper second Kirschner wire that pierces to the back lower place, couples together formation fixed structure by each Kirschner wire with semi-ring bar in inner side on condyle of femur, 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, thereby rotation extender lengthens by Fracture of femur end distraction reduction extension rod.5, after near end of thighbone pears shape nest opening insertion pulp cavity guide pin, expansion marrow, inserting intramedullary needle fixes.
First, second described extender one end is connected to one section of extension rod upper, the other end and links together by another section of screw thread and extension rod.While rotating extender, threaded another elongated segment bar 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, on each pipe pipe clamp, have bolt 36, bolt middle part is set with pad 34, and the both sides of pad are provided with the first pipe clamp body 32 and the second pipe clamp body 35 by screw thread respectively, on two pipe clamp bodies, have respectively arcuate groove 33, the end face of bolt has polygonal groove 31.Two pipe clamp bodies are when arranged side by side, can be used for being connected and fixed between two parallel pipes or bar, and two pipe clamp bodies are when vertical, can be used for being connected and fixed between two vertical pipes or bar, while being connected and fixed, and in the polygonal groove of bolt, insertion tool, rotating bolt.The pipe or the bar that are connected are positioned at arcuate groove.The structure of tube needle clamp is similar to pipe pipe clamp, no longer describes in detail.
