Abstract
The utility model relates to a limbs tubular shaft fracture hoop device made of memory alloy, which comprises a bone plate. The utility model is characterized in that: the bone plate is a long frame shape with circular arc shaped horizontal short frames and arc shaped aliform encircling plates inclined inwardly of long frames at the two sides. Wings are arranged at the upper part of the aliform encircling plates at the two sides and are staggered and embedded with each other; at least three wings are arranged on the aliform encircling plates at the two sides. The utility model has the advantages that the operation is simple; the interference to the extramedullary blood supply of the fracture end is small; the stability of the fracture end can be maintained in auxiliary; the abilities to the intramedullary fixed shearing resistance, rotating resistance and fold bending resistance are increased. The utility model can be applied directly to the oblique fractures of the metacarpal and the phalanges, and no plaster external fixation is needed after the operation, which is helpful for the early functional training and the function of the injured limbs recovery.
Description
Technical field
This utility model relates to a kind of extremity tubulose shaft fracture hoop driver, particularly a kind of extremity tubulose shaft fracture memorial alloy hoop driver.
Background technology
At present, treatment extremity tubular bone shaft fracture, internal fixation device and householder method commonly used are as follows: (1) medical stainless steel plate: the shortcoming of existence is the thin easy bending of general steel plate class, fractures, and bone stump does not have pressurization, easy concurrent bone does not connect connects disease, so the class steel plate is eliminated day by day.The compression steel plate class has overcome the deficiency of general steel plate, and can be disposable, passively to the bone stump pressurization, but studies show that it can damage the periosteum of the bone growth promoting of relying in nearly 40 years, the stress-shielding effect after fixing produces osteanabrosis.(2) medical stainless steel intramedullary needle intramedullary needle class: as elasticity round needle, Ender pin, Δ shape pin, V-arrangement pin etc., be used for upper limb tubulose non-bearing bone more and be used for the lower limb load-bearing bone less, because pulp cavity width differs, needle body is difficult to form at effective 3 or 4 to be fixed, shearing resistance, anti-revolve, anti-separate not enough, often cause into the generation that angle, bone does not connect connect disease, postoperative needed with fixing long times such as external spread frame, and patient feels inconvenience very much; Entry point is near joint portion in addition, and backshank influences the functional recovery training in joint.Anti-rotation of interior pinning class and anti-separating power are stronger; present clinical wound is used more extensive; be particularly suitable for tubular bone and walk crosswise, lack diagonal or comminuted fracture; but for long oblique fracture, long sphenoid piece; tight or the pressurization of embedding between difficult formation fracture end in the operation; can not effectively keep stability, loosening or displacement loses its internal fixed protective effect between fracture end, easily forms curved nail, broken nail phenomenon.
Summary of the invention
The purpose of this utility model is the thin easy bending of medical corrosion resistant plate in the solution prior art, fractures, and bone stump does not have pressurization, easy concurrent bone does not connect connects disease, and compression steel plate can damage the periosteum of the bone growth promoting of relying, and the stress-shielding effect after fixing produces osteanabrosis.Medical stainless steel intramedullary needle intramedullary needle class differs owing to pulp cavity width, it is fixing that needle body is difficult to form effective or at 3 at 4, shearing resistance, anti-ly revolves, anti-ly separates not enoughly, often causes into the generation that angle, bone does not connect connect disease, postoperative needed with fixing long times such as external spread frame, and patient feels inconvenience very much; Entry point is near joint portion in addition; backshank influences the functional recovery training in joint; anti-rotation of interior pinning class and anti-separating power are strong still for long oblique fracture, long sphenoid piece; tight or the pressurization of embedding between difficult formation fracture end in the operation; can not effectively keep stability; loosening or displacement loses its internal fixed protective effect between fracture end, easily forms the problem of curved nail, broken nail phenomenon.Technical solutions of the utility model design extremity tubulose shaft fracture memorial alloy hoop driver, comprise blade plate, it is characterized in that: blade plate is a long frame shape, its laterally short edge is circular arc, the both sides long frame edge has the arc wing of introversion to encircle plate, the wing of both sides is encircled plate top wing, and the wing on both sides is encircled the staggered phase embedding of wing on the plate, and both sides wing is encircled plate top and had three wings at least.The utility model has the advantages that can be simple to operate, disturb little to the outer blood fortune of fracture end marrow, the complementary stability of keeping fracture end, improve the shearing resistance of marrow internal fixation, anti-ly revolve, the warping resistance ability, can directly use for palm or phalanx, phalanx oblique fracture, and without Gypsum Fibrosum class external fixation, help early functional training and recovery and hinder the limb function after the operation.
Description of drawings
Accompanying drawing 1 is a structural upright sketch map of the present utility model,
Accompanying drawing 2 is low temperature flow sketch map of the present utility model (dotted line is the flow shape),
Accompanying drawing 3 is a user mode sketch map of the present utility model,
Comprise blade plate 1 among specific embodiment Fig. 1, it is characterized in that: blade plate 1 is a long frame shape, its laterally short edge 2 is circular arc, both sides long frame edge 3 has the arc wing of introversion to encircle plate 4, the wing of both sides is encircled plate 4 tops wing 5, the wing on both sides is encircled the wing 5 staggered phase embeddings on the plate 4, and both sides wing is encircled plate 4 tops and had three wings 5 at least.Fig. 2 is that extremity tubulose shaft fracture memorial alloy hoop driver of the present utility model is placed on the flow sketch map in low temperature (0 ℃) normal saline, X line according to the tubulose backbone during use is taken the photograph sheet, select corresponding model, what its wing was encircled plate 4 encircles the diameter of internal diameter less than the tubulose backbone, art is preceding with extremity tubulose shaft fracture memorial alloy hoop driver soaking disinfection, put into 0 ℃ of normal saline flow of aseptic ice chest, expose bone stump near fracture, and fracture end inserted 0 ℃ of normal saline internal cooling, place extremity tubulose shaft fracture memorial alloy hoop driver 1 at fracture---2, blade plate 1 places fracture that one side of displacement trend is arranged, with warm saline (25---36 ℃) extremity tubulose shaft fracture memorial alloy hoop driver rewarming is acted on mutually to original recovery of shape and with the tubulose backbone, finish the key fixation of fractures of tubulose, Ultimum Ti has the thermoelastic martensitic transformation lattice, can obtain unidirectional, two-way, the memory effect of omnidirectional, deformation quantity up to 8%, 45---the restoring force of 85kg/mm2, elastic modelling quantity that the more important thing is it can be according to the needs of people's bone, carry out Artificial Control, can provide appropriate active persistent pressure power, the healing that helps fracturing to fracture.
Claims (2)
