Background technology
Clinically, the fracture of elongated tubular skeleton is a kind of commonly encountered diseases, along with popularizing of vehicle, the comminuted fracture relevant with vehicle is more and more, when comminuted fracture occurs the time, need to incision of skin and to adopt steel wire that comminuted bone piece is tied up fixing, owing to being attached with tough and tensile fascia and muscle around the skeleton, the outside of skeleton is crossed also has nerve, blood vessel and soft tissue.When adopting the comminuted bone piece of wire binding, for steel wire encircling around skeleton, realize tying up reliably, the tissue that needs to be attached to the skeleton outside is peeled away in order to penetrate steel wire rope.When carrying out these operations, need to reduce as much as possible wound, protect to greatest extent skeleton tissue on every side, steel wire can't penetrate but wound is again too small, for this reason, generally adopts clinically the multi-functional orthopedic steel wire traction to clamp to finish wearing of steel wire.Application number is: 201120064412.3 Chinese patent description discloses a kind of steel wire forceps for orthopedics, this draws pincers and contains symmetrical two parts caliper, and two caliper middle parts link to each other by rotating shaft, and both sides are divided into jaw and clamp handle before and after the rotating shaft, sub-circular after two jaw docking, two jaws are the different hollow pipe of thickness, coupling radially in one of them hollow pipe external diameter and another, and the end can be inserted, this steel wire forceps for orthopedics is rational in infrastructure, easy to use, still, the function singleness of this traction tongs.
The utility model content
The purpose of this utility model provides a kind of multi-functional orthopedic steel wire traction pincers, to solve the problem of error steel wire forceps for orthopedics function singleness in the prior art.
In order to realize above purpose, this utility model adopts following technical scheme: a kind of multi-functional orthopedic steel wire traction pincers, comprise the first and second calipers arranged in a crossed manner, two calipers are hinged by rotating shaft at both infalls, the part that the first and second calipers are in before the rotating shaft is the first and second associated jaw portion, being in rotating shaft part afterwards is the first and second clamp handle parts, the front portion of two associated jaw portion is hollow pipe, the outside of two associated jaw portion is provided with a steel wire port at the position near rotating shaft, the leading section of described the first associated jaw portion and the second associated jaw portion is pyramidal structure, the front end face of the first associated jaw portion is inclined-plane toward the outer side, and the front end face of the second associated jaw portion is the inclined-plane that coincide and cooperate with the front end face of the first associated jaw portion towards inboard.
Described steel wire port is the Long Circle hole along the length direction extension of corresponding associated jaw portion.
The rearward end away from rotating shaft of described the first and second clamp handles part is provided with the limit fastener structure that prevents that two clamp handles partly are separated from each other.
Described limit fastener structure comprises that an end is fixedly installed on the inboard arc profile of the first clamp handle part and an end is fixedly installed on the inboard arc dop of the second clamp handle part, arc profile and arc dop are mutually stacked, the center of circle of arc profile and arc dop all is on the axis of rotating shaft, be provided with the end tooth that tooth top tilts laterally on the surface that arc profile and arc dop match, the end tooth of arc profile and arc dop blocks mutually joins.
Described end tooth is the triangle end tooth.
The front end face of the first associated jaw portion of the present utility model and the second associated jaw portion coincide and cooperates, can well guiding steel wire, and, because the front end face of the first associated jaw portion and the second associated jaw portion is the inclined-plane, so that the front end of the first associated jaw portion and the second associated jaw portion all has respectively a tip, the tissue around the skeleton not only can well be peeled off in two tips when traction steel wire, and can also realize the function of fracture reduction fixing clamp, in addition, the leading section of the first associated jaw portion and the second associated jaw portion is pyramidal structure, when needs when skeleton is holed, first this structure is prevented between two tips of the first associated jaw portion and the second associated jaw portion, then rotate the first associated jaw portion and the second associated jaw portion, the pyramidal structure of two associated jaw portion will be got the hole at the skeleton of need boring, realize the function of card punch.This utility model function is more, can one pincers multiplex, avoid in operation, changing frequently apparatus, have very large realistic meaning.
The steel wire port that arranges on this utility model is Long Circle, is the tangent line position with caliper, can conveniently steel wire be penetrated in the steel wire port, has kept simultaneously the intensity of caliper.
The rearward end away from rotating shaft of the first and second clamp handles part of the present utility model is provided with the limit fastener structure that prevents that two clamp handles partly are separated from each other, buckle structure can guarantee that two associated jaw portion are in the state that is closing in operating process, handled easily has strengthened practicality of the present utility model.
