Abstract
The utility model relates to a shank locking intramedullary pin operation traction reduction frame, comprising a bracket, a draw bar and guide rods; the utility model is characterized in that the guide rods are arranged on both ends of the bracket; both ends of the draw bar are provided with sliding blocks which are arranged on the guide rods and can left and right slide on the guide rods; adjusting screw rods are arranged between the sliding blocks and the bracket; the draw bar is connected with a foot pedal by a fixed rod; the bracket is provided with a big foot-support frame. The technical proposal of the utility model is that when the knee joint is in the flexed position, the lower end of the shank and the foot are a pair of acting force and reacting force; based on the theory, the reduction frame can make the sliding blocks left and right move by the adjusting screw rod, which simultaneously drives the draw bar to move for drawing the shank, thereby reaching the intension of the traction and the reduction of the fracture part of the shank.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of tibia interlocking intramedullary nail operation reduction by traction frame particularly.
Background technology
Fracture of tibia is modal extremity fracture, accounts for 13.7% of whole body fracture.The treatment of fracture of tibia nothing more than closed reduction external plaster fixation, exterior fixation bracket fix, closed draw resets and the steel plate or the interlocking intramedullary nail that cut reduction by traction fixed this several method.But in the therapeutic process of this several method, reduction by traction in the operation and all will just finishing having under many people's the close fit when expanding marrow and implanting intramedullary pin, and traction, reset and keep shakiness, big and the poor accuracy of rough handling, blindness, reduction by traction in the art and fixedly tend to have than big-difference because of doctor's personal experience, directly the quality of influence operation need manually be controlled when C-arm electricity is saturating in addition sometimes, has increased the intake of medical personnel X line.
When the fracture of tibia end of displacement passes through reduction by traction, promptly be equivalent to the fracture of stability is become instable fracture, will apply an active force and counteracting force to the far-end and the near-end of fracture limbs (shank).Wherein, for skin traction, can finish this a pair of active force during flexing knee joint position preferably applies, promptly bearing axial thrust force at the rear portion far away and the foot of thigh, but also to when implanting interlocking intramedullary nail, bear an external carbuncle simultaneously, in other words, own tension force of limbs in the time of just will bearing fracture traction and reset and an external stress when importing intramedullary pin.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of tibia interlocking intramedullary nail simple in structure, easy to use operation reduction by traction frame is provided.
In order to solve the problems of the technologies described above, this utility model is by the following technical solutions: a kind of tibia interlocking intramedullary nail operation reduction by traction frame, comprise support, draw bar, guide post, it is characterized in that: described guide post is arranged on the two ends of support, and the two ends of described draw bar respectively are provided with slide block, and slide block is installed on the guide post, and horizontally slip along guide post, be provided with adjusting screw(rod) between slide block and support, draw bar links to each other with pedal by fixed bar, and support is provided with a big leg support.
By following technical scheme as can be known, distal part of femur when this frame that resets utilizes the knee sprung position and foot are a pair of active force and counteracting force principle, can make the slide block move left and right by adjusting screw(rod), drive draw bar simultaneously and move and draw shank, thereby reach the traction of fracture of tibia end and reset.This utility model is simple in structure, and is easy to use, reduction by traction efficient height, satisfactory for result.Economize the people, laborsaving, save time, long service life, not fragile, can shorten operating time, improve the quality and the success rate of tibia intramedullary interlocking nail fracture of tibia greatly, and the reduction by traction process is soft, can not resemble manual traction can cause resetting local soft tissue than poly-injury.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of tibia interlocking intramedullary nail operation reduction by traction frame, comprise support 1, draw bar 2, guide post 3, guide post 3 is arranged on the two ends of support 1, and the two ends of draw bar 2 respectively are provided with slide block 4, and slide block 4 is installed on the guide post 3, and horizontally slip along guide post 3,1 on slide block 4 and support are provided with adjusting screw(rod) 5, and draw bar 2 links to each other with pedal 7 by fixed bar 6, and support 1 is provided with a big leg support 8.Can make slide block 4 along guide post 3 move left and right by adjusting screw(rod) 5, drive draw bar 2 simultaneously and move, adjust the position of pedal 7, reach the purpose of bone reduction by traction.
Support 1 two ends are provided with slide block 9, and draw bar 2, support 1 are provided with chute.After adopting this technical scheme, slide block 9 slides along the chute on the support 1, and slide block 4 slides along the chute on the draw bar 2, makes this reduction by traction frame vertically, laterally all can regulate, thereby uses more conveniently, and the people of suitable all ages and classes level uses.
In addition, this is gone up also has the 10 feasible bone tractions and fixing of four spicule towing pads, so the bone that it also can be used as shank prolongs and the external fixation brace.Use " tibia interlocking intramedullary nail operation reduction by traction frame " row tibia intramedullary interlocking nail fracture of tibia 14 examples, operation economize the people, laborsaving, save time, reduction by traction is lightly accurate, closed reduction drift bolt rate height shortens operating time.This while also can use as tibia exterior fixation bracket and tibia lengthening support.The tibia interlocking intramedullary nail operation reduction by traction frame of this design voluntarily, can improve the quality of tibia intramedullary interlocking nail fracture of tibia greatly, filled up a technological gap of tibia intramedullary interlocking nail fracture of tibia aspect in the art, this design concept novelty, and usefulness more than one is worthy of popularization.
This apparatus is a blank on the present orthopaedics, how the orthopedist carries out reduction by traction with artificial maneuver when carrying out fracture of shaft of tibia closed reduction interlocking intramedullary nail internal fixation and Wicresoft's internal fixation with steel plate now, waste time and energy and closed draw to reset to power not high, often change the open reduction internal fixation again into, the closed draw that artificial maneuver is carried out in the art resets, non-quantitative, ambiguity are answered the people and different, use these lower limb closed draw reattachment surgery device can be laborsaving, save time, quantitative, qualitative.Improved the success rate of fracture of shaft of tibia closed reduction interlocking intramedullary nail internal fixation and Wicresoft's internal fixation with steel plate.
