Description
Technical field
It the utility model is related to medical instruments field, and in particular to a kind of steel needle fixing tractor.
Background technology
Adjustable steel needle fixing tractor is common a kind of medical instrument in operation, is drawn when Orthopedic correction is performed the operation
With.Steel needle fixing tractor commonly used in the prior art, is equipped with draw point fixed seat including fixed link, motion bar, motion bar more,
Rear haulage in draw point insertion fixed seat.Wherein it is disadvantageous in that, because draw point fixed seat is non-movable structure, once draw point
Larger through the angle after soft tissue and fixed seat deviation, draw point is just difficult to be inserted into fixed seat, makes troubles for operation.
Utility model content
In order to realize the controllability of draw point bearing, facility is provided for operator, the utility model provides a kind of
Steel needle fixing tractor.
The utility model adopts the following technical solution：
A kind of steel needle fixing tractor, including main frame, main frame connection fixed link and motion bar, main frame and fixed link
Fixed vertical connects, and main frame is equipped with sliding groove, and motion bar is stretched into sliding groove, and the first fastening bolt is compressed through sliding groove
Motion bar, the first fixing bolt play the role of fixed motion bar position.The motion bar and fixed link one end are respectively connected with steel
Pin fixed block, draw point fixed block are cylinder, and cylindrical structural causes draw point fixed block is convenient to rotate, set inside draw point fixed block
There is draw point to penetrate hole, draw point using when insertion draw point penetrate in hole, draw point can rotate adjustment position with draw point fixed block.
Specifically, motion bar and fixed link and the connection mode of draw point fixed block are：
The motion bar and fixed link one end are equipped with draw point fixed part, and the draw point fixed part is groove, draw point fixed block
It is placed in groove, the second fastening bolt compresses draw point fixed block through groove, and the second fastening bolt and recess sidewall are screw thread
Connection, the second fastening bolt can fix the position of draw point fixed block after draw point fixed block adjusts angle.
It is bellmouth that the draw point, which penetrates hole, facilitates draw point to be inserted into, and be tightly fastened draw point.
The main frame connects hanging seat by connecting rod, and hanging seat is equipped with steel wire rope mounting hole, and operator is in steel wire rope
Steel cable is put in mounting hole, by pulling steel wire rope just to pull the draw point fixed traction of the utility model accordingly
Device.
When the utility model is used, after draw point through being attached to after the soft tissue on correction of bone, by adjusting work
Position of the lever in sliding groove, can adjust the distance between two draw point fixed blocks, draw point fixed block is rotated to certain
Angle, is suitable for the angle of draw point, and then draw point is inserted into draw point fixed block, is consolidated draw point fixed block by fastening bolt
It is fixed, so as to fulfill effective traction.
The advantages of the utility model and have the beneficial effect that：
The utility model is simple in structure, can the distance between two draw points of flexible adaptation and draw point angle, facilitate medical care
Personnel, which are adjusted, to be used.
