Description
Technical field
This utility model relates to a kind of medical apparatus and instruments and device, specifically in bone surgery for tubular bone fracture partly being carried out to interior fixing a kind of intramedullary needle for the treatment of the human body clavicular fracture.
Background technology
As everyone knows, clavicular fracture is common fracture, the non-operative treatments that in the past adopted and external fixation commonly used more, and malunion, disunion is many.Be fixed with outward and adopt steel plate and a Ke Shi intramedullary needle to fix two kinds of methods, but mortality is high, the former otch is large, need peel off periosteum and second operation is got steel plate; With a Ke Shi intramedullary needle, fix, two ends all will pass cortical bone, make hook, are embedded in subcutaneously, and its otch is many or long, and damage is large, also needs second operation to get pin; With the intramedullary needle of full thread, fixing shortcoming is that diameter is thick, lacks flexibility fixing, is unfavorable for the fracture site Self-pressurizing agri.At present, in bone surgery, great majority are to utilize blade plate and bone screw fracture site to be implemented fixing, total says that human body clavicle fracture reduction operation is more complicated, periosteum stripping is more, to fracture site blood fortune, destroy many, nonunion and inside-fixture are loosening, and blood vessel and brachia plexus injury under clavicle occurs, and the downright bad steel plate dew of local skin etc.Clavicle does not have special intramedullary needle, and present multiplex osseous pin is used as the clavicle intramedullary needle, has stress concentration, can not control the rotation of fracture end, a little less than bed knife, easily deviates from etc. not enough.The fracture face compressive stress that importantly the clavicle intramedullary needle existed is in the past concentrated, can not be controlled the fracture end rotation, easily deviates from and the problem such as secondary damage easily occurs unanimously well be not resolved, now become human body clavicle fracture reduction operation operate in problem in the urgent need to address.
Summary of the invention
The purpose of this utility model is: the problem existed for prior art, and to design and develop and provide simple in structure, volume is little, lightweight, and cost is low, a kind of intramedullary needle for the treatment of the human body clavicular fracture easy to use.
This utility model solves the technical scheme that its technical problem adopts: a kind of intramedullary needle for the treatment of the human body clavicular fracture is characterized in that: by syringe needle 1, and needle body 6, backshank 4 forms, and wherein, needle body 6 rear ends and backshank 4 front ends are provided with changeover portion 5, as Fig. 1, shown in 2,4.
Said syringe needle 1 is designed to the Rhizoma Sparganii cone, and syringe needle 1 and needle body 6 rounding ofves of Rhizoma Sparganii cone, as Fig. 1, shown in 2,4.
The triangular prism that said needle body 6 design cross sections are equilateral triangle vertically is provided with groove 2 and notch 3 on a rib of needle body 6, and, the needle body 6 of the triangular prism that cross section is equilateral triangle and changeover portion 5 rounding ofves of syringe needle 1 rear end and backshank 4 front ends, as Fig. 1, shown in 2,3.
Said backshank 4 design cross sections are circular cylinder, and the changeover portion 5 of backshank 4 fronts is designed to cone, and, changeover portion 5 respectively with needle body 6 rear ends and backshank 4 front end rounding ofves, as Fig. 1, shown in 2,4.A kind of intramedullary needle for the treatment of the human body clavicular fracture of present technique can adopt the metal material manufacture nontoxic to human body, and concrete manufacture process can adopt integrally formed method manufacture.
The operation principle of present technique and work process
:present technique is owing to adopting by syringe needle 1, needle body 6, the intramedullary needle that the changeover portion 5 that backshank 4 and needle body 6 rear ends and backshank 4 front ends are provided with forms, and be prismatic, as Fig. 1, 2, shown in 4, in use, more stable in inserting clavicle, self can not rotate, each rib is blunt round, increased the contact surface of intramedullary needle and bone, reduced the stress concentration of bone, the prismatic design can be controlled the rotation of fracture end, and, the Rhizoma Sparganii structure is counter-bending, torsional rotation force is larger, the annular knurl processing can be carried out in prismatic intramedullary needle surface, the thicker grain in surface, increased frictional force, intramedullary needle is difficult for becoming flexible.In addition, intramedullary needle a groove vertically arranged, can send out deformation when intramedullary needle is driven into the clavicle internal therapy, therefore, when fracture end has light activity, can descend not occur looseningly because of bed knife, the intramedullary needle operation technique be fairly simple, can avoid the generation of blood vessel and brachia plexus injury under clavicle.Clinically, using clavicle prismatic intramedullary needle fixing will be the ideal chose for the treatment of clavicular fracture.In concrete operation process, first expose fracture end, drive in the wrong direction and squeeze into intramedullary needle, by fracture anatomical reduction, then direct motion squeezes into intramedullary needle, fixing clavicle, fracture fixation is stable but also flexible pressurization not only, can guarantee the success of patient's fracture operation and the immediate union of fracturing.The scope of application of present technique is not limited to the content on description, and by above-mentioned technology contents, present technique can be used for treating ulnar fracture by this intramedullary needle within not departing from scope of the present invention, carries out little various change and modification.Because intramedullary needle is long prism shapes, the intramedullary needle of the dissimilar different parts choice for use different model that the medical worker can fracture according to the patient in operation process, guarantee successful surgery.
The advantage of present technique and beneficial effect: reasonable in design, compact conformation, operation technique is simpler, peel off few, fracture site blood fortune is destroyed little, can be avoided the generation of blood vessel and brachia plexus injury under clavicle, carry out bone grafting around the more convenient fracture end at clavicle, fracture fixation is more firm, prevent that blade plate from occurring in fracture healing process loosening, increase the reliability of fracture fixation, promote union of fracture, guarantee successful surgery, reduce the characteristics such as patient suffering.
