Abstract
The utility model discloses an olecranal-fracture hairpin type claw hook. The claw hook is formed through oppositely folding a kirschner wire with a diameter of 1.5 to 2 mm in half and then bending the kirschner wire to form a U-shaped structure with different lengths at the two ends, wherein the end of the claw hook where the two ends of the kirschner wire are positioned is named as a hook part (1), while the other end of the claw hook is named as an arm part (2); the hook part (1) is 20 to 40 mm longer than the arm part (2), so that the hairpin type claw hook can be formed; a firm bone screw via hole (2a) is formed in the end of the arm part (2) and is manufactured into an arc shape at the turning part of the hook part (1) and the arm part (2) according to the shape of an olecroanon; the width of the claw hook is 8 to 12 mm, while the length of the claw hook is 60 to 70 mm. According to the utility model, through a method of combining intramedullary fixing and extramedullary fixing, the fixing of a fracture end is improved and the stability of a joint is recovered; moreover, the claw hook has the characteristics of simple structure, short incision and the like.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used for the treatment of fracture, relates in particular to a kind of grapple structure that is used for the treatment of olecranal fracture.
Background technology
Olecranal fracture is the common damage of ancon, is grown up common.Except the most advanced and sophisticated avulsion fracture of minority olecroanon, most of cases are the intra-articular fractures that involve semilunar notch, due to the contraction of triceps brachii, fracture is easy to occur shift separation, the accurate reduction of the fracture, fixedly be to prevent joint instability, prevent the effective measures of osteoarthritis and other complication.
For the treatment of olecranal fracture, mainly adopt in tension band or dissection armor plate fixing at present.There are the complication such as interior fixing loosening, plate exposure, structure and operation is more complicated, medical treatment cost is higher.
Utility model content
This utility model improves for above-mentioned technical problem, intends providing a kind of hairpin-type grapple, by the fixing mode that immobile phase is combined outside marrow in marrow, strengthens fixing, the recovery stability of joint of fracture end; And have simple in structure, draw materials easily, the feature such as cost is low, otch is short.
For this reason, the technical scheme that this utility model adopts is: a kind of olecranal fracture hairpin-type grapple, by the Kirschner wire of 1.5～2mm diameter be first folded in half into bifilar after, be bent into again two ends length inconsistent " U " shape structure, the one end at Kirschner wire two ends place is called hook portion (1), the other end is called arm (2), and described hook portion (1), than the long 20～40mm of arm (2), forms hairpin-type grapple; The termination of described arm (2) is provided with hard matter bone screw via hole (2a), makes arc in hook portion (1) and the turning point of arm (2) according to the profile of olecroanon; The width of described grapple is 8～12mm, and the length of grapple is 60～70mm.
Operation method: patient's horizontal position, brachial plexus nerve resistance anesthesia, suffering limb near-end upper gasbag tourniquet.After elbow, make the curved incision of protruding radiad, can appear fracture face, be convenient to interior fixing and covering grapple.Successively cut, by oar side direction ulnar side free skin flap, appear fracture face, remove hemarthrosis, little free bone fragment.For the larger sclerite being connected with periosteum, should sew up and reset with adjacent periosteum.After parking position accuracy, with the drill bit of diameter 3mm, through the parallel pulp cavity that pierces of olecroanon mid point ulnad far-end, its degree of depth is advisable to exceed fracture line 20mm.Grapple is inserted in the tunnel having bored and the olecroanon of holding, more than the length of its grapple should exceed fracture line 20mm.Its arm and crista ulnae fit tightly, and under axial pressure, vertically or approximately hole to far-end diagonal at fracture far-end, and screwing is fixed grapple.Movable elbow joint is shown in that fracture end is stable, strengthens sewing up and stretches elbow device, successively closes otch.Bend the holder of 90 ° of neck wrist suspender belts of elbow in front.Can be fixing outward without Gypsum Fibrosum.Within postoperative 1～2 week, can make elbow joint function takes exercise.
After olecranal fracture, it is irregularly shaped mostly fracture end is, after concavo-convex involutory, the parking position accuracy of fracture end, it is normal that the relation of olecranon semilunar notch and trochlea of humerus is recovered.Identical with the width of grapple to the diameter in tunnel that far-end bores by olecroanon, more than the degree of depth exceedes fracture line 20mm, the grapple inserting fits tightly in tunnel therewith, form in marrow fixing, add arm one piece of screw on ulna dorsal part ridge of depressing at grapple and, to control the separation of fracture end and to prevent that it from swinging, form marrow fixing outward; Strengthen sewing up and stretch elbow device, recover the balance of power of elbow joint muscle, it is fixing that three stablizes fracture end and joint.
Be preferably, the diameter of described Kirschner wire is 1.5mm.
The beneficial effects of the utility model are: this grapple has merged in marrow to be fixed with marrow and fix two kinds of principles outward, the arm of grapple and hook portion are bidimensional parallel construction, if what it was suffered advocates along the longitudinal pulling force of grapple arm, also be the axial tension that Kirschner wire itself bears, what be enough to resist triceps brachii stretches elbow strength; And can carry out early functional exercise, reduce joint accretion, promote bone healing, thereby prevent the generation of the complication such as osteoarthritis, ankylosis; Meanwhile, because the hook portion of grapple is longer than arm, correspondingly increase the fixing stability of grapple, reduced incision length, and simple in structure, low cost of manufacture.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
In conjunction with the olecranal fracture hairpin-type grapple shown in Fig. 1, Fig. 2, by the Kirschner wire of 1.5～2mm diameter be first folded in half into bifilar after, then be bent into two ends length inconsistent " U " shape structure.The one end at Kirschner wire two ends place is called hook portion 1, forms the long end of " U " shape structure; The other end is called arm 2, forms the short end of " U " shape structure.The hook portion 1 of grapple is parallel with arm 2 bidimensionals, and hook portion 1 is than the long 20～40mm of arm 2, and global approximation hair clip shape, therefore be referred to as " hairpin-type grapple ".
The termination of arm 2 is provided with hard matter bone screw via hole 2a, and size is passing through as degree for hard matter bone screw.Make arc in hook portion 1 and the turning point of arm 2 according to the profile of olecroanon.The width of grapple is 8～12mm, and the length of grapple is 60～70mm.
It is that 2mm Kirschner wire is made that hairpin-type grapple also can be selected diameter.
