The patellar fracture fixing device comprises two patella concentrators which are mounted on an I-shaped fixing plate; the two patella concentrators symmetrically mounted on an opening of the fixing plate through a rotation shaft; the middle part of the fixing plate is in threaded connection with an adjusting screw rod; the lower end of the adjusting screw rod is connected with an arc plate; and the adjusting screw rod is in threaded sleeve joint with an adjusting handle. Compared with the prior art, the patellar fracture fixing device has the characteristics of reasonable design, simple structure, convenience in use and the like; the patella concentrators can be used for clamping firmly, and have a good fixing effect; and meanwhile, the patellar fracture fixing device provided by the utility model has the advantage of low manufacturing cost, thus reducing the burden on of patient and having great values in popularization and application.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, a kind of specifically Patella fracture fixture simple in structure.
Background technology
In the prior art, when the clinical treatment Patella fracture, need use patella claw, especially in nursery work.The patella claw of using at present generally is the overall structure of the integral type processed with expensive memorial alloy; Realize the distortion adjustment by memorial alloy, need the medical worker free-hand fixing during use, but this free-hand mode that patella claw and patella are combined closely; Because strength is very little; And can not carry out gradual pressurization, make patella claw and patella not to combine closely, and then the bigger phenomenon in fracture slit occur; Cause the union of fracture required time longer, take action to live to the patient and bring inconvenience.
Summary of the invention
The technical assignment of this utility model is the deficiency that solves prior art, and a kind of Patella fracture fixture simple in structure, easy to use is provided.
The technical scheme of this utility model realizes by following mode, this a kind of Patella fracture fixture, and its structure comprises patella claw; Patella claw is installed on the fixing head; This fixing head is " worker " shape, and patella claw is provided with two and be installed in the opening part of fixing head through the rotating shaft symmetry, the middle part of the said fixing head adjusting screw(rod) that is threaded; The lower end of this adjusting screw(rod) is connected with arc, screw thread socket one adjusting tap on the said adjusting screw(rod).
The handle of said adjusting tap is three fork-shapeds and evenly is provided with.
The beneficial effect that this utility model is compared with prior art produced is:
Characteristics such as that a kind of Patella fracture fixture of this utility model has is simple in structure, easy to use, be skillfully constructed can be regulated the grip strength between the patella claw through adjusting screw(rod), and adaptability is good; Clamping is firm; Avoid the patella claw displacement, come off, good fixing effect, this utility model also has the advantage of low preparation cost simultaneously; Relieve patient ' s burden has good value for applications.
