21.52mm, 8.05mm, 20.08mm, coronoid process sclerite is just smaller, which results in after reseting fracture block in art, carries on the back from ulna
The blind Kirschner wire fixation coronoid process sclerite difficulty of wearing of lateral palmar is larger, it is possible that repeated multiple times Kirschner wire fixation in art
Process, and repeatedly thread a needle and easily lead to coronoid process sclerite and thoroughly crush, the iatrogenic injury of fracture is thereby resulted in, hand can be extended
The art time, and certain complication is brought to clinical treatment.
Summary of the invention
In view of the above-mentioned problems, being mainly used for auxiliary the purpose of this utility model is to provide a kind of elbow fracture reduction forceps
It helps in orthopaedic disease treatment, the accurate position of the implantation of Kirschner wire in fracture dislocation of elbow art, to make Kirschner wire guider
It can be quickly and accurately implanted into Kirschner wire fixation fracture of ulna coronoid process block, greatly shorten operating time, while avoiding because repeatedly
Sclerite caused by threading a needle crushes.
To achieve the above object, the technical scheme adopted by the utility model is that:
A kind of elbow fracture reduction forceps, comprising:
The first clamp handle and the second clamp handle being pivotally connected by a pivot；
First clamp handle is the first pincers rostral relative to the front end of pivot, and the rear end relative to pivot is the first gripping
Portion, second clamp handle are the second pincers rostral relative to the front end of pivot, and the rear end relative to pivot is the second grip part；
The first pincers rostral and the second pincers rostral are arc-shaped, and the radian of the first pincers rostral clamps rostral less than second, the
The bending radius of one pincers rostral is greater than the second pincers rostral；
The free end of first pincers rostral is equipped with a ball point, and the free end of the second pincers rostral is equipped with and the ball point
One kirschner needle sleeve of cooperation.
Further the, the specification of the kirschner needle sleeve is the inside and outside diameter of 1.5mm/2.0mm().
Further, when first clamp handle and the second clamp handle are switched to a cooperation station with pivot, the ball point
It is formed and is cooperated with Kirschner wire sleeve.
Further, the end face of the kirschner needle sleeve forms sawtooth.
Further, it is described first pincers rostral radian be 95 ° to 125 °, it is described second pincers rostral radian be 180 ° extremely
265°。
Further, the bending radius of the first pincers rostral is 1.2 times to 1.8 times of the second pincers rostral bending radius.
It further, further include an adjusting rod, second grip part opens up a through-hole, and the adjusting rod is logical across this
Hole, and one end be fixed in the first grip part close to the second grip part side；
The surface of the adjusting rod is formed with one section of external screw thread, and an adjusting nut is sheathed on the tune by screwing with external screw thread
Pole, and it is located at side of second grip part far from the first grip part.
By taking above-mentioned technical proposal, on the basis of existing Medical Devices clamp reduction forceps, add at side pliers tip
Add kirschner needle sleeve, while the serrating processing in barrel contacts bone face one end, increases with bone face contact frictional force to increase clamping
Stability, other side pliers tip spheroidization processing, increases the stability of clamping coronoid process bone block.Pass through adjusting rod, Neng Gou
Different clamping degree keep clamping force.Arm of force radian design in pliers two sides is asymmetric, and the lesser side of radian is conducive to conveniently put
Enter in wound, fixed coronoid process.
Technical solution provided by the present application can fast and accurately be implanted into Kirschner wire, filled up to lack at present and close for elbow
Save the technology of the guiding device of the fixed dedicated implantation Kirschner wire of coronoid process sclerite.
Detailed description of the invention
Fig. 1 is the structure composition schematic diagram of the elbow fracture reduction forceps in an embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description.
As shown in Figure 1, providing a kind of elbow fracture reduction forceps in one embodiment, comprising:
The first clamp handle 1 and the second clamp handle 2 being pivotally connected by a pivot 3；
