Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of orthopedic kirschner pin guiding device.
Background technique
Fracture refers to a kind of disease for causing bone parts due to wound or pathology etc. or being broken completely, in treatment bone
It when folding, needs again to reset bone, after bone reduction, because its is unstable, is easy to happen and shifts again, therefore will be using difference
Method be fixed in position, so that it is gradually healed, the method for currently used fixation has outer fixation and interior
Fix two kinds.
Kirschner wire fixation is a kind of method of common interior fixation, and it is solid to generally use Kirschner wire to some unstable fractures
It is fixed, clinically for short bone, irregular bone, close on articular fracture fix and trans-articular it is fixed using Kirschner wire fixation effect compared with
It is good.In fixation Kel's needle, it is necessary first to one end of Kirschner wire is mounted on electric drill, be then turned on electric drill, by kirschner stylus printer
Enter the bone that need to be fixed, but accurately squeeze into the more difficult assurance of Kirschner wire with position by a predetermined angle, especially similar to wrist scaphoid this
The multi-joint face irregular bone of sample needs to extract Kirschner wire, squeezes into again, once when the angles and positions inaccuracy squeezed into
Operation often needs repeatedly to squeeze into, and has virtually aggravated Accessory injury, has further destroyed blood supply, has extended operating time, Jin Erying
Therapeutic effect is rung.The angles and positions for squeezing into Kirschner wire are difficult to grasp, so the once success rate of Kirschner wire fixation operation
It is lower.For this purpose, Chinese utility model patent CN206934165U discloses a kind of Kirschner wire guider, including soft tissue protection
Device, vertical pole and sliding bar, one end of vertical pole are equipped with soft tissue protector, and the other end is equipped with slidable sliding bar；Institute
Stating sliding bar includes horizon bar, and one end of horizon bar is vertical with vertical pole to be connect, and the other end is connected with pole, the end setting of pole
There is target spot, horizon bar is arranged in parallel with soft tissue protector, and target spot is corresponding with the center of soft tissue protector, due to vertical
When being provided with slidable sliding bar on bar, therefore target spot being directed at the position for needing needle to be pierced by, by the flexible of sliding bar and
The moving in rotation of vertical pole makes the sleeve top of guider reach ideal access point, tightens vertical pole suitable for the bone of different thicknesses
On screw keep sliding bar fixed after, patient handles the protector and vertical pole connecting place of guider on the other hand, can another hand will
Kirschner wire is pierced from sleeve direction, is pierced by from target position, thus squeezes into Kirschner wire, and still, which makes
With having the disadvantage in that in the process
(1) one piece of Kirschner wire can only be squeezed into every time, can not squeeze into more pieces of Kirschner wires simultaneously；
(2) during surgery, it sometimes for intensity is further increased, needs to more pieces of Kirschner wires are squeezed at same sufferer, i.e.,
More pieces of Kirschner wires are intensively squeezed into, are needed in the position for identifying the Kirschner wire squeezed into, during squeezing into, the Kirschner wire of reaching the last
Guider need to adjust the position of vertical pole and sliding bar repeatedly, and repeatable accuracy is poor, easily causes large error, further increase positioning
Difficulty, and operation difficulty is big, is unfavorable for shortening operating time, reduces infection and bleeding, and reduce the risk of operation；
(3) it is only capable of vertically adjusting the position of soft tissue protector, it can not be laterally adjusted, in use, needing opposite
Patient part repeatedly adjusts slide bar and vertical pole repeatedly may cause secondary damage to appropriate location to patient part, and adjust
Difficulty is big, time and effort consuming.
(4) Kirschner wire exit points easily cause Kirschner wire to be pierced by accidental injury nerve, blood vessel and other groups without soft tissue protector
It knits.
In view of this, being badly in need of improving existing Kirschner wire guider, enhance its positioning accuracy, it can be adjacent
More pieces of Kirschner wires are squeezed at position, Kirschner wire is avoided to be pierced by accidental injury nerve, blood vessel and its hetero-organization, and have positioning fast simultaneously
Speed, the characteristics of being conveniently adjusted, and then operating difficulty is reduced, shorten operating time, reduces risk.
Utility model content
Technical problem to be solved in the utility model is existing Kirschner wire guider because positioning accuracy is poor, cannot be in phase
Ortho position, which is set, squeezes into more pieces of Kirschner wires, position adjustment very complicated, the slow and inconvenient defect adjusted of locating speed, caused operation
Difficulty is big and the high problem of operation risk.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is to provide a kind of orthopedic kirschner pin and leads
To device, including support rod, sliding bar and abutment sleeve, the support rod is slidably arranged in one end of the sliding bar,
The other end of the sliding bar is equipped with multiple sight holes, for inserting abutment sleeve；
The lower end of the support rod is equipped with pole, and the pole is parallel to each other with the sliding bar, and the pole is equipped with
Multiple location holes, the location hole and the sight hole face.
In the above scheme, the top of the support rod is equipped with and the cunning integrally formed with sliding rail, the sliding bar
The through-hole of rail adaptation, the sliding rail are threaded through in the through-hole, and the outer wall of the through-hole is equipped with set lever.
In the above scheme, the cross-sectional shape of the sliding rail is semicircle.
In the above scheme, one end of the abutment sleeve is equipped with the positioning region in cone tip shape.
In the above scheme, the abutment sleeve is set as three, and internal diameter is respectively 10mm, 15mm and 20mm.
In the above scheme, the location hole is blind hole.
The prior art is compared, the utility model, can once squeeze into more pieces of Kirschner wires, can basis without repeatedly installation positioning
It needs to select multiple abutment sleeves, the kirschner pin position squeezed by each abutment sleeve is different, squeezes into before not needing identification
The position of Kirschner wire does not need the position of adjustment support rod and sliding bar, can squeeze into more pieces of Kirschner wires during squeezing into,
Difficulty is reduced, is conducive to shorten operating time, reduces infection and bleeding, and reduce the risk of operation, also, is fixed in once mounting
Behind position, by sight hole, can aim at it is multiple penetrate position, reduce installation positioning number, improve speed.
