Abstract

The utility model provides a femoral fracture opening reduction device, and belongs to medical apparatuses and instruments. The femoral fracture opening reduction device comprises a first extension rod and a second extension rod, the two ends of the first extension rod and the two ends of the second extension rod are connected together respectively through a first tube clamp and a second tube clamp, the middles of the two rods are provided with a first extender and a second extender respectively, one end of the first extension rod is fixedly provided with a Steinmann needle sleeve tube through a third tube clamp, a Steinmann needle is arranged in the Steinmann needle sleeve tube, one end of the second extension rod is fixedly provided with a semi-ring rod through a fourth tube clamp, a first Kirschner needle is fixed on the semi-ring rod through a first tube needle clamp and a second tube needle clamp, and a second Kirschner needle which is perpendicular to the first Kirschner needle is fixed on the semi-ring rod through a third tube needle clamp. According to the femoral fracture opening reduction device, when the closed reduction is carried out, the device can be combined with a magnetic navigation intramedullary needle to treat the fracture of the femoral shaft, the difficult problem of the closed reduction is solved, flexibility of the intraoperative operation is greatly increased, and meanwhile the complication caused by the application of a traction bed to conduct the reduction is avoided.

Description

The Fracture of femur pulling off reset device

Technical field

This utility model provides a kind of medical apparatus and instruments, especially a kind of orthopaedics apparatus.

Background technology

Fixedly be the goldstandard for the treatment of fracture of shaft of femur in the femur fixing interlocking intramedullary nail, yet although X-ray examination is quite universal in the art, still there is certain difficulty at present in Fracture of femur closed reduction technology wherein.In addition, too much application X-ray examination also is that most surgeon institute is unacceptable in the art, 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 present most orthopedist adopts in the fracture of shaft of femur art, but owing to the reason of extension table special posture has limited the motility that operates in the art, the operation difficulty particularly in healthy and strong or fat patient's art for build particularly, and cause easily in the art complication such as fracture of femoral neck.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of Fracture of femur pulling off reset device, to improve its result of use.

This utility model is to realize like this, the 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 the steinman pin sleeve pipe by the tee pipe pipe clamp, in the steinman pin sleeve pipe steinman pin is arranged, one end of the second extension rod is fixed with the semi-ring bar by the 4th pipe pipe clamp, the first Ke Shi pin is fixed on the semi-ring bar by the first tube needle clamp and the second tube needle clamp, and the second Ke Shi pin vertical with the first Ke Shi pin is fixed on the 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 unite magnetic navigation intramedullary needle treatment fracture of shaft of femur, not only solved the difficult problem of closed reduction, greatly increase the motility that operates in the art, and avoided the complication that causes in response to resetting with extension table.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing further specifies this utility model.

As shown in drawings, the Fracture of femur pulling off reset device of this utility model, 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, steinman pin 3 is arranged in the steinman pin sleeve pipe, 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 the semi-ring bar by the first tube needle clamp 11 and the second tube needle clamp 16, and the second Ke Shi pin 15 vertical with the first Ke Shi pin is fixed on the semi-ring bar by the 3rd tube needle clamp 14.

During use, as follows in the operating procedure of associating under the magnetic navigation: 1, pierce steinman pin 3 in ilium anterior superior iliac spine position, the diameter of this pin is 4.0mm, and needle angle is the 15 degree angles that inwardly upwards respectively tilt, with the steinman pin casing pipe sleeve outside steinman pin.2, inwardly pierce the first Kirschner wire 10 in external epicondyle of femur, the place ahead is partially inboard from front upper second Kirschner wire that pierces to the back lower place on condyle of femur again, and each Kirschner wire is coupled together the formation fixed structure with the semi-ring bar, and 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 the rotation extender lengthens with Fracture of femur end distraction reduction extension rod.5, inserting intramedullary needle behind near end of thighbone pears shape nest opening insertion pulp cavity guide pin, the expansion marrow fixes.

Described first, second 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.When rotating extender, threaded another elongated segment bar inserts in the 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, at each pipe pipe clamp bolt 36 is arranged, the bolt middle part is set with pad 34, and the both sides of pad are equipped with the first pipe clamp body 32 and the second pipe clamp body 35 by screw thread respectively, on the two pipe clamp bodies arcuate groove 33 is arranged respectively, 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 the bar, when two pipe clamp bodies are vertical, can be used for being connected and fixed between two vertical pipes or the bar, when being connected and fixed, in the polygonal groove of bolt, insertion tool, rotating bolt gets final product.The pipe or the bar that are connected are positioned at arcuate groove.The structure of tube needle clamp is similar to the pipe pipe clamp, no longer describes in detail.
