Technical field
The utility model relates to a kind of medical instrument more particularly to a kind of fixation devices for Kirschner wire.
Background technique
Kirschner wire is fixed steel needle in orthopaedics is common, for fixing the short and small bone fractured or avulsion fracture iso-stress is little
Folding is fixed.Kirschner wire is after passing through bone, and both ends are fixed by Kirschner wire traction bow, as shown in Figure 7.Since traction bow is generally than needing
The position to be fixed is wide, such as foot, and usually by having certain distance between fixed position and the both ends of traction bow, this is easy for
So that being slided between the both ends of traction bow when bone is fixed on Kirschner wire.
Utility model content
In view of the above problems, the utility model is directed to a kind of fixation device for Kirschner wire, can guarantee by
The position of kirschner pin puncture is fixed between traction bow without sliding.
The fixation device for Kirschner wire of the utility model comprising: interior rod piece and outer rod piece；
The first grooving is longitudinally formed with along interior rod piece；The periphery of interior rod piece is formed with external screw thread；The second end of interior rod piece
It is formed with cover, gauze or cotton balls are fixed in cover；The gauze or cotton balls extend beyond the edge of cover and stretch to outside；
The second grooving is longitudinally formed with along outer rod piece；The cross section of outer rod piece is formed as C-shaped；The inner circumferential of outer rod piece is formed
There is internal screw thread, outer rod piece mode engaged through the thread is rotatably engaged on the periphery of interior rod piece；
When first grooving and the second grooving face, the fixation device for Kirschner wire can be cut via described first
Slot and the second grooving and cover on Kirschner wire；When first grooving and the second grooving misplace, the fixation for Kirschner wire
Device is maintained on Kirschner wire；
The first end of outer rod piece is used for against the inside of the end of the traction bow to Kirschner wire, and the second end of interior rod piece is used for
It is resisted against on the point of puncture of patient.
Preferably, the first end of the outer rod piece further passes through connection strap and is connected with nut cap, for covering in Kirschner wire
End.
Preferably, medicinal alcohol is adsorbed in the gauze or cotton balls.
By the fixation for Kirschner wire that the utility model is arranged between the end of traction bow and the point of puncture of patient
Device can prevent the position that is punctured of patient from sliding on Kirschner wire.

Specific embodiment
In the following, passing through the fixation device for Kirschner wire of Detailed description of the invention the utility model.
The fixation device for Kirschner wire of the utility model comprising: interior rod piece 20 and outer rod piece 10.
The first grooving 23 is longitudinally formed with along interior rod piece 20；The periphery of interior rod piece 20 is formed with external screw thread；Interior rod piece 20
Second end be formed with cover 21, gauze or cotton balls 22 are fixed in cover 21；On cover 21 and gauze or cotton balls 22 accordingly
Offer notch 25, notch 25 and 23 connection of the first grooving and point-blank.Notch 25 can be closable, such as cover
Son 21 has certain elasticity, can open under external force, external force restores to the original state and is closed after removing.Gauze or cotton balls 22 prolong
It extends over the edge of cover 21 and stretches to outside, it is possible thereby to the puncture point contact with patient.It is adsorbed in gauze or cotton balls 22
Medicinal alcohol can prevent point of puncture from infecting in this way.
The second grooving 11 is longitudinally formed with along outer rod piece 10；Outer rod piece 10 is formed as tubulose, the cross section of outer rod piece 10
Be formed as C-shaped；The inner circumferential of outer rod piece 10 is formed with internal screw thread, including outer rod piece 10 mode engaged through the thread is rotatably engaged
On the periphery of rod piece 20.By rotation, relative position between adjustable outer rod piece 10 and interior rod piece 20, thus according to needing
Adjust the length of entire fixed device.
When the first grooving 23 and the second 11 face of grooving, the fixation device for Kirschner wire can be via the first grooving 23 and
Two groovings 11 and cover on Kirschner wire；First grooving 23 and the second grooving 11 are due to rotation and when misplacing, for consolidating for Kirschner wire
Determine device to be maintained on Kirschner wire without falling down.
The first end of outer rod piece 10 is used for against the inside of the end of the traction bow to Kirschner wire, and the second of interior rod piece 20
Hold the point of puncture for being resisted against patient.
In a second embodiment, the first end of outer rod piece 10 further passes through connection strap 12 and is connected with nut cap 13, for covering
It is exposed to avoid its end and stab the people of surrounding in the end of Kirschner wire.
In use, the first grooving for being first and the second grooving face, as shown in figure Fig. 1,5, will fixed device cover gram
On family name's needle；Then rotate outer rod piece so that the first end of outer rod piece be resisted against the inside of the end of traction bow and the of interior rod piece
It leans against on the point of puncture of patient to two ends, in this way, just completing prevents the site of puncture of patient from sliding on Kirschner wire.
