Abstract
The utility model relates to an external fixing support for pelvis fracture, and belongs to the technical field of medical instruments for pelvis fracture recovery. The external fixing support functions in fixing and clamping for pelvis fracture to achieve the objective of recovery. The external fixing support comprises clamping-needle assemblies (1), moving shafts (2) and adjustable extension tubes (3). The external fixing support is characterized that every two same assemblies are combined into an arc-shaped pelvic floor support; by a universal ball joint arranged in the middle of each clamping-needle assembly (1), bone needles can be fixed at any position conveniently; four to six bone needles can be assembled on the external fixing support; the whole assembly can be semicircular, oval or square, and the shape of the whole assembly is determined according to conditions of patients' pelvises and injuries. The external fixing support can translate and rotate, the universal ball joints are subjected to special technical processing, and accordingly, the whole external fixing support is quite applicable to external fixation of pelvis needles.
Description
Technical field
This utility model relates to a kind of exterior fixation bracket for peviform bone fracture, belongs to the technical field of medical instruments of peviform bone fracture recovering, for playing the effect fixing to clamp after peviform bone fracture, thereby arrives the object of rehabilitation.
Background technology
The fracture of peviform bone is the very common wound class case of orthopedics department, and former Therapeutic Method is more loaded down with trivial details, and spicule is fixing not quite reasonable, brings new pathological changes to patient, is all generally that spicule is installed at the two ends of a straight-bar, and the angle of spicule is easily limited.
Summary of the invention
This utility model, in conjunction with the advantage of prior art, improves its deficiency, and design is a kind of rational in infrastructure, simple to operate, the outer fixed product of basin bone of new generation of fixation.
The technical solution of the utility model is as follows:
The exterior fixation bracket of fracturing for peviform bone is by pressing from both sides needle assembly (1), shifting axle (2), adjustable extension tube (3) composition, it is characterized in that: folder needle assembly (1) is connected with shifting axle (2) by ball head universal, spicule can be located according to concrete degree of impairment, by ball head universal freely adjusting angle until suitable, if the position of damage is larger, can regulate the distance of shifting axle to reach suitable length, shifting axle (2) is connected with adjustable extension tube (3) by screw, adjustable extension tube (3) is connected with symmetrical adjustable extension tube (3), the connection of two extension tubes is the interlocks of circular dentation phase, can 360 rotations be unlikely to again slippage, make its whole support body not only can in line but also can have certain angle.The inner side of basin bone becomes comminuted fracture, and at this moment the position of spicule is rotated in the both sides of femur, and the connecting rod in the middle of at this moment just needing has individual angle, could not interfere with impaired position.If os pelvicum fracture is directly over lower limb, the at this moment connection of spicule only needs a linear type.Along with the healing state of bone injury, still can optionally finely tune therebetween each junction.
This utility model compared with prior art has the following advantages:
1 spicule angular adjustment is more convenient to be suitable for
2 structural designs more rationally meet the irregularly shaped of pelvis
The material of 3 whole support bodys is 2A12-T4 (aluminium alloys), and high strength low weight is convenient for carrying
4 handling eases and processing cost are lower, are suitable for medical industry and apply.
Accompanying drawing explanation
Fig. 1 is peviform bone outside fixed frame for external osteosynthesis overall structure schematic diagram.
Fig. 2 is folder needle assembly and adjustable schematic diagram of being connected of shifting axle.
Fig. 3 is that symmetrical two adjustable extension tubes connect selection schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The first step, doctor first determines the position of a side seam pin according to the position of bone injury, respectively spicule is arranged in folder pin assembly (1), to press from both sides pin assembly (1) is connected with shifting axle (2) again, ball head universal arbitrarily adjusting angle wouldn't be locked, adjustable extension tube (3) is installed, second step, same method is installed spicule and the support body of opposite side, the 3rd step, according to extremely suitable length of the length of the size adjustment shifting axle of pelvis, after angle, two adjustable extension tubes (3) are interlocked and tightened, the 4th step, adjust the angle of angle lock dead ball head gimbal, see Fig. 1.
Bone injury is between healing stage, change the relative position of itself and adjustable extension tube (3) through the situation screw that can regulate shifting axle (2) to locate of check, the angle between two adjustable extension tubes (3) also capable of regulating to reach better state as Fig. 2.
Claims (1)
1. the exterior fixation bracket of fracturing for peviform bone is by pressing from both sides needle assembly (1), shifting axle (2), adjustable extension tube (3) composition, it is characterized in that: folder needle assembly (1) middle part ball head universal is connected with shifting axle (2), can regulate arbitrarily the angle of inclination of spicule, shifting axle (2) can move by axially parallel in adjustable prolongation assembly (3), be convenient to finely tune the needle gage of spicule, adjustable prolongation assembly (3) can extend arbitrarily according to the size of patient's build, two extend assembly (3) joint utilizes the interlock of flute profile phase, after fixing, be difficult for the phenomenon that rotates.
