Abstract
The utility model relates to a double-clamp type fracture reduction fixer, comprising two clamping arms which are articulated through a hinge shaft. The head grid ends of the clamping arms oppositely bend to form a holding hole; the tail part of each clamping arm is of a clamping handle which is provided with a handle fixing hole; one of the head grid ends of the clamping arms is a double-head grid end; an operation hole is arranged between the holding hole and the hinge shaft; and two double-clamp type fracture reduction fixers can be connected into a whole by a fixing rod. In the double-clamp type fracture reduction fixer, the double-head grid end is cooperated with a single-head grid end to prevent movement or slide of an instrument caused by muscular contractility, thereby avoiding dislocation of a wound during temporary fixing. The holding hole arranged between the holding hole and the hinge shaft is convenient for fixing fixers at both sides of the wound after temporary fixing without affecting later operative procedure. Two fracture reduction fixers are connected into a whole by the clamping fixing rod, thereby having no inconvenience of manual holding during temporary fixing, and more importantly, avoiding second dislocation of broken ends of fracture.
Description
Technical field
This utility model relates to a kind of bone surgery set, is specially a kind of apparatus that is used for reduction of the fracture operation.
Background technology
Extremity fracture is the clinical modal case of orthopaedics.Conventional Therapeutic Method is first by manual reset, and temporary fixed with like instrument such as bone holding forceps, then with marrow nail or steel plate permanent fixation.Because fracture site adheres to the pulling force that muscle produces, therefore behind manual reset, must carry out temporary fixed with bone holding forceps or like instrument.Existing temporary fixed instrument mainly is bone holding forceps or claims gripper clamp etc., it is made up of two hinged clampers, wherein every clamper includes the clamping limb of front curvature and the handle at rear portion, and the clamping limb of two bendings constitutes a clamping hole, and holder is arranged on the handle.As Chinese patent 200720158804.x disclosed " the special-purpose clamping fixation clamps of bone surgery "; Disclosed 200520125055.1 " the special-purpose clamping fixation clamps of a kind of bone surgery "; Disclosed 03214466.0 a kind of " reduction of the fracture bone holding forceps "; Disclosed 200720176799.5 " a kind of orthopaedics reduction forceps "; 03207762.9 disclosed " a kind of bone holding forceps " etc. are structurally similar substantially.The weak point of this apparatus is that clamping limb is a single armed up and down, and the clamping shakiness is easily slided, and often causes operative failure.The secondth, the front portion is the single hole structure, carry out after the clamping that screw is fixed or steel plate fixedly the time working place very little, in order to increase the working place, two clamp-on holder spacings must strengthen, far away apart from wound, when causing resetting the operation of failure, particularly comminuted fracture and several sections of fracture easily, more increase operating difficulties.The 3rd is not connect between two clamp-on holders, need have the special messenger to help during temporary fixed, and carelessness is arranged slightly, and the fracture displacement promptly can take place the bone after resetting once more.
Summary of the invention
This utility model has designed a kind of pair of jaw type fracture reduction fixator at the deficiency that above-mentioned prior art exists, and has solved temporary fixed manipulate inconvenience, mutually unrelated and single armed clamping shakiness between two temporary fixed pincers, problems such as easy slip.
A kind of pair of jaw type fracture reduction fixator of the present utility model, comprise two by the hinged clamping tong arm of hinge, clamping hole of two crooked relatively formations of gripper clamp arm head portion grip end, the afterbody of clamping tong arm is a holding handle, the handle fixing hole is arranged on holding handle, and it is characterized in that having a gripper clamp arm head portion grip end is the double end grip end.
A kind of pair of jaw type fracture reduction fixator is characterized in that between clamping hole and hinge handle hole being arranged.
A kind of pair of jaw type fracture reduction fixator is characterized in that having two ends to be shaped on the fixed bar of draw-in groove, is shaped on the card post that mates with described draw-in groove on double end clamping tong arm handle, adopts fixed bar that two two jaw type fracture reduction fixators are connected as a single entity.
A kind of pair of jaw type fracture reduction fixator, the draw-in groove quantity that it is characterized in that cassette fixed bar two ends are 4-6.
A kind of pair of jaw type fracture reduction fixator of the present utility model adopts the double end grip end to cooperate with the single head grip end, avoided effect because of myotility that apparatus is moved or slided, kept the length after the reduction of the fracture simultaneously, can guarantee temporary fixed during fracture site no longer misplace, the operation carry out smoothly.A clamping hole is set between clamping hole and hinge, and the fixed apparatus of wound both sides, convenient temporary fixed back does not influence next step operation technique.With the cassette fixed bar two fracture reduction fixture devices are connected as a single entity, save temporary fixed during manually the inconvenience of holding up, main is guarantees that the fracture site both sides can not misplace once more.

The specific embodiment
Below in conjunction with accompanying drawing to a kind of pair of jaw type fracture reduction fixator of the present utility model.
With reference to accompanying drawing 1, a kind of pair of jaw type fracture reduction fixator of the present utility model is made up of two clamping tong arms that are hinged by hinge 3, and wherein the head grip end of two tong arms is crooked relatively, forms a clamping hole 5, the inboard of clamping hole is shaped on burr 10, prevents to skid during the clamping.Have one to be double end grip end 6 (as shown in Figure 2) in above-mentioned two head grip ends, another is single head grip end 4 (as shown in Figure 3).The afterbody of clamping tong arm is a holding handle, and handle fixing hole 1 is arranged on holding handle.The top of Wan Qu head grip end is that a handle hole 8 is arranged between clamping hole 5 and the hinge 3 relatively, this handle hole is set can makes things convenient for next step operation to carry out, and as operation time space spaciousnesses such as upper steel plate, screw or bone marrow nails, the visual field is good, is beneficial to operation and carries out smoothly.There is folder tooth 7 to separate between two holes, guarantees the shape of clamping hole 5 by folder tooth 7.Of the present utility model pair of jaw type fracture reduction fixator also has a fixed bar as shown in Figure 6, at the two ends of this fixed bar draw-in groove 11 is arranged, card post 12 with draw-in groove 11 couplings is arranged on double end clamping tong arm handle 2, two fracture reduction fixators with the fracture site both sides when temporary fixed are connected as a single entity, and the two can be moved.The skeleton of guaranteeing the fracture site both sides no longer misplaces.Guarantee carrying out smoothly of next step operation.
Of the present utility model pair of jaw type fracture reduction fixator adopts the stainless steel material making that is fit to make medical apparatus and instruments.
During use, after fracture site resetted, a two jaw type fracture reduction fixator is set respectively in the fracture site both sides, wherein double end grip end 6 up, single head grip end 4 below.Grip end clamps back injection such as Fig. 4 and screw shown in Figure 5/mother and fastening in the fixing hole 1 of single head clamping tong arm handle 9 and double end clamping tong arm handle 2 with bone.With fixed bar the handle of two two jaw type fracture reduction fixators is fixed at last, the two is connected as a single entity.
The fixed structure of said fixing bar is not limited only to draw-in groove, card rod structure, also can adopt other similar structures.
