Abstract
The utility model relates to an inner fixture for the fixing and reposition of fractured diaphysis of long bones of limbs. The utility model is characterized in that the fixture adopts arc hinges formed by the hinging connection of splints with concave circle arcs to coat and fix fracture parts, and the contact area of the reposition fixture and a broken bone is large; the utility model has the advantages of high reliability in coating and pressing, convenient operation, short operating time and high success ratio one time, after the fracture is cured, complication does happen, being favorable to make the operation by beginners, and the fixture is widely used for temporary fixation of major fracture open reposition of the diaphysis of long bones, particularly femurs and broken bones.
Description
Utility model is that a kind of long bone of limbs is done the fracture inner fixation surgical instrument.
When long bone of limbs is done fracture open reduction internal fixation, involutory temporary fixed to fracture site, normally by as bone holder tools such as three-jaw bone holding forceps.Ubiquity resets and fixes difficulty, fixing unsteady situation in the operation, not only directly influences to perform the operation and carries out smoothly, and influence union of fracture.Owe tight as clamping, knochenbruch easily slides, fixing unstable, easily produce when knochenbruch is holed and move and dislocation, need repeated multiple times to reset, not only increased the complexity in the operation, but also easily cause hole and screw not exclusively identical, and cause screw to be difficult for tightening, postoperative is easy to generate loosening slippage, form malunion or disunion, need operation once more; The clamping tension injures iatrogenic fracture in then easily causing the fixation steel plate bending, fracture or causing.For the damaged fixation of fractures such as bone grafting that needs of fracture of shaft of femur and comminuted fracture and bone, difficulty especially, the fracture more to broken bone, also must be earlier with steel wire or silk thread twine help fixing.Up to now do not have the fixed operating theater instruments of the ideal help of a kind of practicality, this has not only increased operating difficulty, and what influence was performed the operation carries out smoothly, and operating time is long, and a success rate of operation is not high, has directly influenced operation reduction internal fixation curative effect.
The purpose of utility model is to provide a kind of temporary fixed apparatus of extremity fracture operation reduction that is suitable for, and makes the particularly more comminuted fracture of fragment of fracturing, and it is fixing easy, firm to reset, and operating time is shortened in convenient operation, improves success rate of operation and curative effect.
The utility model reduction fixture device is characterized in that strap is a circular arc, and by the extension arm of the clamping plate one side camber hinge that is hinged, constitutes the bone pipe support of opening, causes parcel disconnected, broken bone is compressed.
Describe this utility model in detail below in conjunction with accompanying drawing.With rigid plastic material (as rustless steel) punch process clamping plate 1 in the arc-shaped, arc size and degree of crook are looked key arc, with enclose not for well.Curved splint one side is respectively washed away a part, make it concavity, the extension arm 2 of two spill arc plates, one side is hinged, the arc hinge of operation window 3 is arranged in the middle of forming.The hinged of hinge can be that assembling connects, or fixedly connected, wherein especially to be fixedly hinged to excellent, can have hinge hole at the extension arm close end of arc hinge, connects with bearing pin.For the convenient reset case of observing, can on hinge curved splint 1, have some observation ports 4, observation port can be any geometric figure, is good with the oval hole especially wherein.
Appear fracture site by open reduction internal fixation routine, laying blade plate after fracture end tentatively resetted is pressed on the reduction fixture device extension arm on the blade plate then, make blade plate be positioned at the operation window below, close up hinge, parcel is disconnected, broken bone, stresses on reduction fixture device with bone holding forceps (as three-jaw or two pawl bone holding forceps) again, observes reset case from observation port, further tighten bone holding forceps after adjusting satisfaction, cause the involutory of fracture site fixed.To fracture boring, the screw of screwing on unclamps bone holding forceps after connecting by the operation window place, and the removal holder closes wound by layered suture.As adopt the fixing fracture of intramedullary needle, and operation method routinely then when pin during to fracture end, fixes the fracture site intramedullary needle with reduction fixture device and bone holding forceps and can pass through the broken ends of fractured bone smoothly, and fixing back releasing reduction fixture device closes wound by layered suture.
Adopt this utility model not only can make fracture comprise that the more reduction of the fracture of broken bone is fixing reliable, firmly, nor can trauma bone plate and produce iatrogenic fracture, make things convenient for operation technique, shorten operating time greatly, reduce patient's wound and misery.Operation one-time success rate height, union of fracture is good, no complication.Utility model also can help the skilled synthetism of abecedarian, smoothly operation.
Accompanying drawing is the structural representation of utility model.
1---curved splint; 2---extension arm; 3---operation window; 4---observation port.
Embodiment: press the accompanying drawing structure, make the arc hinge with the corrosion resistant plate punching press, the place, axle center leaves the operation window that operation technique is used, and has some oval observation ports on the curved splint.
Claims (4)
1, a kind of long bone shaft fracture reduction fixture device of being made up of clamping plate 1 is characterized in that clamping plate are circular arc, and is hinged the arc hinge of middle band operation window 3 by the extension arm 2 of clamping plate one side.
2, by the described reduction fixture device of claim 1, it is characterized in that having on the curved splint observation port 4.
3, by the described reduction fixture device of claim 2, it is characterized in that observation port is an oval.
