Technical field
The utility model belongs to medical surgical machinery field, and in particular to a kind of orthopaedics Kirschner wire positioner.
Background technique
For orthopaedics severe deformity of spine patient, operation consent needs wardrobe basin ring traction, wherein before pelvic ring placement, needs
It to be implanted into Kirschner wire on pelvis (ilium), by bilateral anterior superior spine to posterior superior iliac spine, be implanted into Kirschner wire at present without effective position
Device, operation rely solely on operating doctor operation skill, and Kirschner wire implantation position is inaccurate.
In bone surgery, it is often necessary to by Kirschner wire is percutaneous and soft tissue pass through pierced after one piece of bone again it is another default
Bone block be fixed.Kirschner wire is that a kind of orthopaedics commonly fixes material, is mainly used for fixing short and small fracture or avulsion fracture
The little fracture fixation of iso-stress is also used in bone surgery in the fixation of interim sclerite, and in general Kirschner wire length is
20 centimeters or so, there are many specifications between 0.5-2 millimeters for diameter.When being performed the operation, since the length of Kirschner wire is longer,
Its drilling direction is slightly offset, and can be made last bore position that biggish deviation occur, is unable to reach expected position, existing mesh
Before, doctor can fluctuate Kirschner wire with tool in the notch of operation, deflect the tip of Kirschner wire to preset direction, so
It is crept into again afterwards, but because Kirschner wire has elasticity well, so that stirring effect is not it is obvious that so that bone
The accurate fixation of folding part position can not often be accomplished disposably to succeed, it is often necessary to which be loaded fixation repeatedly, greatly reduces efficiency；
And Kirschner wire, when being punctured, the direction and position of its drilling are different in varied situations, not can guarantee each
A position can guarantee the accuracy and efficiency of drilling when being crept into.
