Abstract
The utility model relates to an orthopedics external fixing device, which comprises a guide rail, a bone needle clamping component positioned on the guide rail and a bone needle, wherein, the bone needle clamping component comprises a seat body and a screw, wherein, a guide rail hole which is matched with the guide rail, an oppositely clamping groove which is communicated with the guide rail hole and a screw hole passing through the oppositely clamping groove are arranged on the seat body. The screw is positioned in the screw hole. A bone needle hole is arranged above the screw and a female lock is arranged below the screw. The quantity of the bone needle clamping component on the guide rail is no less than two. The utility model has the advantages of simple structure, few modifying positions and convenient utilization and operation and is particularly suitable for a double-edge external fixing device for leg bone knitting.
Description
This utility model relates to a kind of medical apparatus, and specifically a kind of fixture of bone-setting treatment afterwards that is used to fracture belongs to orthopaedic medical treatment utensil technical field.
When enforcement bone-setting treatment in fracture back takes place, the following method of normal employing: on two terminations of knochenbruch, hammer into spicule, by the outer monolateral or bilateral external fixator fixed bone spicule of limbs, regulate the position of spicule on holder the correct butt joint of fracture site is coincide, fixed bone spicule keeps correct butt joint to coincide state until fracture butt joint healing.95228561.4 number Chinese patent discloses a kind of orthopaedics external fixer that is used for above-mentioned Therapeutic Method, this fixed mount adopts " U " shape support and the structure of removable spicule clamping assembly is set on " U " shape support, but satisfied the instructions for use that the spicule hole multidimensional on the spicule clamping assembly moves, structure is complicated, parts are many, overall dimensions is big, the adjustment position is many, use operation than unfavorable factors such as troubles but it exists simultaneously, and it can only use as unilateral external fixator, and range of application is also narrower.Be the use operation of convenient external fixator at fractures, improve the level of fractures, need the development structure more simple, it is few to adjust the position, uses the more convenient orthopaedics external fixator of operation.
The purpose of this utility model is to provide a kind of structure more simple, and it is few to adjust the position, uses the more convenient orthopaedics external fixator of operation.
The purpose of this utility model is achieved in that
A kind of orthopaedics external fixator, its characteristics are that it comprises guide rail 1, is positioned at spicule clamping assembly and spicule 3 on the guide rail, described spicule clamping assembly comprises pedestal 2, screw 6, pedestal is provided with guide rail hole 4, to clip slot 5, screw hole 7, guide rail hole and guide rail, clip slot is communicated with guide rail hole, screw hole runs through clip slot, and screw is positioned at screw hole, and the screw top has spicule hole 8, below that locknut 9 is arranged, spicule hole and spicule coupling, the quantity that is positioned at spicule clamping assembly on the guide rail is at least two.
Said fixing device, the quantity of described guide rail are 2, and the quantity of spicule clamping assembly is 4 on each guide rail.
This utility model is adopted and is had the following advantages:
1. pedestal can rotate and along the guide rail slippage around guide rail, and screw can rotate arbitrarily in screw hole, and two guide rails can satisfy the adjustment function of use that spicule hole multidimensional moves by the spicule hole along spicule in opposite directions or opposing slippage;
2. simple in structure, compact, overall dimensions is little, parts are few, are easy to processing and fabricating, cost of manufacture is low;
3. only need just can realize the adjustment of spicule hole multi-dimensional direction by a slight locknut 9 easily, the adjustment part potential drop is to minimum, easy and simple to handle;
4. both can be used as unilateral external fixator and used, and also can be used as bilateral external fixator and use, applied widely, the bilateral external fixator when suiting as the shank synthetism especially uses.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model structural representation;
Fig. 2 is the A-A profile of Fig. 1.
When this utility model guide rail quantity is 1, use, when guide rail quantity is 2, use as bilateral external fixator as unilateral external fixator.Figure 1 shows that the embodiment that this utility model uses as bilateral external fixator.
Consult Fig. 1, in the illustrated embodiment, 2 guide rails lay respectively at the both sides of fracture site limbs, and each guide rail is provided with 4 spicule clamping assemblies, and guide rail 1 is a cylinder, and spicule clamping assembly is sleeved on the guide rail 1 by the guide rail hole on the pedestal 24.
Consult Fig. 2, among the figure, what be communicated with guide rail hole 4 on the pedestal 2 is divided into up and down to the folder part the pedestal of clip slot 5 with guide rail hole one side, screw hole 7 is perpendicular to clip slot and run through up and down the folder part, the two ends of spicule 3 can be arranged in the spicule hole 8 of two screws, 6 tops, screw the locknut 9 of screw 6 lower ends, can be in the spicule hole with the spicule clamping, and simultaneously pedestal 2 is clamped on the guide rail 1.Loosening for preventing locknut, spring pad 10 is arranged between locknut and the pedestal.
When depositing after this utility model sale and the use, can and have in the concentrated plastic bag of packing in the lump of guide rail of spicule clamping assembly, deposit and carry also very convenient spicule.
