Abstract
The utility model discloses a kirschner wire holder for reduction of fracture. Circular-arc shaped clamping slots are formed in two symmetrical sides of a main frame which is wide in a lower part and narrow in an upper part; a sleeve is arranged in the clamping slot in the lower part of the main frame; kirschner wires are arranged in the clamping slots; sleeves for stabilizing the kirschner wires are arranged on the lower parts of the clamping slots; outer threads on the upper part of the main frame are sleeved on the upper parts of the kirschner wires and are then connected with locking blots in a threaded manner; and outer threads, which are used for installing locking bolts, are symmetrically arranged at another two sides of the upper part of the main frame. The kirschner wire holder for reduction of fracture is simple in structure, convenient to use and capable of effectively holding a skeleton, so that the reduction operation is simpler, and the skeleton holding effect is better than the manual skeleton holding effect by many times during an orthopedic surgery of an orthopedist, and therefore, the orthopedic surgery time is saved and pains of a patient are reduced.
Description
Technical field
The present invention relates to a kind of orthopaedics medical apparatus and instruments that resets, particularly a kind of reduction of the fracture Kirschner wire is controlled device, belongs to the field of medical device technology aspect.
Background technology
At present, less invasive techniques is adopted in the orthopaedic trauma reduction of the fracture more, but does not have special Wicresoft's positor.The in the past employing peeled off the son sled and dialled more, but peel off son fully controlling party to, can not control bone reduction, technical sophistication.
Summary of the invention
The present invention is directed to the prior art above shortcomings, provide a kind of reduction of the fracture Kirschner wire to control device.
Be achieved through the following technical solutions order of the present invention:
A kind of reduction of the fracture Kirschner wire is controlled device, the symmetrical both sides that are the narrow body frame of bottom wide upper portion are provided with the draw-in groove that is circular arc, sleeve pipe is located in the draw-in groove of body frame bottom, Kirschner wire is installed in draw-in groove, be provided with the sleeve pipe of firm Kirschner wire in the draw-in groove bottom, the external screw thread on body frame top is threaded with clamping screw after entangling the top of Kirschner wire, and the lateral symmetry in addition on body frame top is provided with the external screw thread that clamping screw is installed.
Body frame and clamping screw are made with plastics or rustless steel or aluminium alloy.Kirschner wire is made with rustless steel or carbide alloy.
For anti-skidding symmetrical both sides at clamping screw are provided with non slip surface.
Sleeve pipe and body frame are integrative-structure or Welding Structure.
Beneficial effect of the present invention: simple in structure, easy to use, can effectively control skeleton, make reset operation simpler, the orthopaedics doctor controls the skeleton effect and is better than manual many times when bone surgery, saved the time of bone surgery, for the patient has reduced the pain of injury.
Description of drawings
Fig. 1 is the structural representation of invention.
Among the figure: 1 body frame, 2 sleeve pipes, 3 Kirschner wires, 4 bones, 5 non slip surfaces, 6 clamping screws, 7 external screw threads, 8 draw-in grooves.
The specific embodiment
As shown in Figure 1, the lateral symmetry that is the narrow body frame 1 of bottom wide upper portion is provided with the draw-in groove 8 that is circular arc, and Kirschner wire 3 is installed in draw-in groove 8, is provided with the sleeve pipe 2 for firm Kirschner wire 3 in draw-in groove 8 bottoms.Lateral symmetry in addition on body frame 1 top is provided with the external screw thread 7 that clamping screw 6 is installed, and for anti-skidding symmetrical both sides at clamping screw 6 are provided with non slip surface 5, both sides are plane bodies in addition.
Sleeve pipe 2 is located in the draw-in groove 8 of body frame 1 bottom, and sleeve pipe 2 is integrative-structure or welding with body frame 1, and the external screw thread 7 on body frame 1 top is threaded with clamping screw 6 after entangling the top of Kirschner wire 3.After the lower tip part of Kirschner wire 3 was put into draw-in groove 8, inserting and passing sleeve pipe 2 backs directly was bone 4 surgical work.
The material of described body frame 1 and clamping screw 6 is made with plastics or rustless steel or aluminium alloy.
The material of described Kirschner wire 3 is made with rustless steel or carbide alloy.
