Abstract
The utility model provides a piece of centralizing bone holding forceps. The main body of the forceps comprises an upper occlusion arm and a lower occlusion arm, wherein the middle part of the upper occlusion arm is hinged with that of the lower occlusion arm through a centralizing bolt; an upper arm pinhole and a lower arm pinhole that are vertical and corresponding to each other are formed at the holding parts at the left ends of the upper occlusion arm and the lower occlusion arm respectively; the upper arm pinhole and the lower arm pinhole are clearing holes for a kirschner wire; the upper arm pinhole and the lower arm pinhole are both funnel shaped; and the thinner parts of the funnels are positioned on holding surfaces. After the reduction of a fracture end is implemented by the centralizing bone holding forceps, a kirschner wire can be put into through the funnel shaped holes to maintain the temporary reduction of the fracture end, so that the fracture end cannot displace when a steel plate is placed at the fracture end, therefore surgery operations are facilitated greatly, and complicated fractures surgery is simple and easy to do.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relate in particular to a kind ofly can conveniently reset, solid
Fixed orthopaedics bone holding forceps.
Background technology
In bone surgery, successful sign is exactly to finish anatomical reduction, strong fixing, be unable to do without bone holding forceps and will finish this operating procedure.Bone holding forceps are as an important tool in the bone surgery, profile and using method are varied, manufacturer differs from one another, and the centralization bone holding forceps are as representative, easy to use because of it, fixation, time saving and energy saving the liking of orthopedist that deeply be subjected to, be substituted other bone holding forceps that reset, become the standing instrument in the orthopedic instrument box.Existing centralization bone holding forceps main body is upper engagement arm and lower engagement arm, upper engagement arm and lower engagement arm middle part are by centralization bolted splice, hinge hole on the lower engagement arm is oblong, and therefore lower engagement arm can relatively go up engagement arm and carry out the clamping that position adjustment adapts to different skeletons; Holding end in upper engagement arm is connected with fastening bolt, and firm bolt is threaded with clamp nut after passing ellipse hole on the lower engagement arm holding end.But the centralization bone holding forceps still can not and be fixed and carry out synchronously fracture end reduction, when fracture end is placed steel plate the fracture end that resets are shifted again, increase patient's amount of bleeding and operation wound, obviously prolong operating time.
The utility model content
The purpose of this utility model provides a kind of fracture end reduction and the fixing centralization bone holding forceps that carry out synchronously, and the fracture end that resets when fracture end is placed steel plate can not be shifted again.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of centralization bone holding forceps, its main body is upper engagement arm and lower engagement arm, upper engagement arm and lower engagement arm middle part are by centralization bolted splice, hinge hole on the lower engagement arm is oblong, holding end in upper engagement arm is connected with fastening bolt, firm bolt is threaded with clamp nut after passing ellipse hole on the lower engagement arm holding end, it is characterized in that: the clamping part at upper engagement arm and lower engagement arm left end has respectively position corresponding vertical upper arm pin hole and underarm pin hole, and upper arm pin hole and underarm pin hole are the hole of passing through of Kirschner wire; Upper arm pin hole and underarm pin hole all are funnel shaped, and the thin section of funnel is located on the clamping end face.
The centralization bone holding forceps have designed funnel shaped hole at the clamping part of the upper and lower engagement arm of arc respectively, after making fracture end reduction, the centralization bone holding forceps can squeeze into Kirschner wire by funnel shaped hole, keep temporarily resetting of fracture end, the fracture end that resets when fracture end is placed steel plate can not be shifted again.And funnel shaped hole can make Kirschner wire squeeze into according to the different different angles of classification of fracture conversion, greatly makes things convenient for operation technique, makes complicated fracture operation simple.
Description of drawings
Fig. 1 is the structural representation of this utility model centralization bone holding forceps:
Among the figure 1, Kirschner wire 2, upper arm pin hole 3, upper engagement arm 4, lower engagement arm 5, centralization bolt 6, clamp nut 7, fastening bolt 8, underarm pin hole.
The specific embodiment
Embodiment 1
As shown in Figure 1, a kind of centralization bone holding forceps, its main body is upper engagement arm 3 and lower engagement arm 4, upper engagement arm 3 and lower engagement arm 4 middle parts are hinged by centralization bolt 5, hinge hole on the lower engagement arm is oblong, holding end in upper engagement arm 3 is connected with fastening bolt 7, firm bolt 7 is threaded with clamp nut 6 after passing ellipse hole on the lower engagement arm holding end, clamping part at upper engagement arm 3 and lower engagement arm 4 left ends has respectively position corresponding vertical upper arm pin hole 2 and underarm pin hole 8, and upper arm pin hole 2 and underarm pin hole 8 are the hole of passing through of Kirschner wire 1; Upper arm pin hole and underarm pin hole all are funnel shaped, and the thin section of funnel is located on the clamping end face.
This utility model centralization bone holding forceps can improve at existing generic central bone holding forceps, have avoided waste, so just can each realize better practical value and the economic worth of this utility model centralization bone holding forceps.
