Abstract
The utility model discloses a frame type girdle device, characterized in that a curl plate is provided with girdle arms from 2 to 10 pairs, and the outer side of each girdle arm is provided with pointed teeth from 2 to 8. The utility model causes the operation to be simple and easy. The utility model has reliable fixation, good plastic forming, good anti-bend, and good torsional action, is especially suitable for the internal fixation of comminuted fracture, and improves the prior internal fixation method.
Description
This utility model relates to technical field of medical, specifically a kind of frame-type girdle device that is used for the employing niti-shaped memorial alloy of fracture fixation.
Present fracture fixation mostly adopts two kinds of methods and corresponding apparatus, the one, adopt steel plate, screw fixings, this method applicable surface is wider, but for the serious comminuted fracture of regionality, broken bone piece is difficult to reset fixing, and the screw holding capacity of steel plate two ends is bigger, easily causes the loosening or fatigue break of screw; The 2nd, nail is fixed the long tube shaft fracture in adopting, though intramedullary pin can prevent the transverse shift and the flexural deformation of fractures effectively, its antitorque effect is poor, can only be used for backbone's epimere fracture, and it is fixing also to be difficult to accomplish to reset for comminuted fracture.
The purpose of this utility model is to provide a kind of frame-type girdle device that is used for fracture fixation, and it can encircle fixing to some smashing fracture segment implementations.
The technical solution of the utility model is achieved in that the frame-type girdle device, it is characterized in that: an arc is provided with 2-10 to encircling arm, encircles arranged outside 2-8 pointed tooth of arm at each.
This utility model compared with prior art has the following advantages:
1, make operation simple and easy to operate;
2, has the persistent pressure fixation;
3, fixing reliable, moulding good, have bending resistance preferably, antitorque effect:
4, be specially adapted to the comminuted fracture internal fixation:
5, can roll over and remove, and reusable.
Because generation of the present utility model breaks through traditional internal fixation method, started a brand-new field of fracture internal fixation, can be widely used in referring to, long diaphysis and tubulose backbone's the comminuted fracture and the internal fixation of old fracture such as metacarpal bone, chi, bone, radius, fibula, clavicle, humerus, tibia, femur, also can be used for bone lengthening.

The utility model will be further described below in conjunction with drawings and Examples
This utility model is according to the position difference of fracture, 2-10 is set to encircling arm 2 on two limits of an arc 1, arm is encircled in i.e. formation and arc fuses, in each arranged outside of encircling arm 2 2-8 pointed tooth 3 arranged, each that is provided with is all opening-like to encircling arm, the size of opening is about about 1/3 of diameter, be convenient to remove and enhanced stability because of considering, a hyphen bar 4 also can be set encircling on the arm, this hyphen bar is in the stage casing that encircles arm, form frame structure, its function can be gathered broken bone, makes girdle device more stable, and when girdle device is removed in union of fracture, available medical screwdriver inserts between hyphen bar and the cortical bone, pries open and encircles arm, takes out girdle device; The several of setting are cylindrical, tubaeform (half-cone), ellipse or prismatic to encircling arm 2 global approximations on arc 1, wherein the many of usefulness mainly are cylindrical and tubaeform two kinds, but what be used for the humerus lower end encircles the arm approximate ovalize that needs to match with humerus, the arm of encircling that is used for tibia need be similar to the tibia cross section, the approximate prismatic that is.Can be triangular in shape at the pointed tooth of encircling the arm arranged outside, crown points to the axle center that encircles arm, so that when fracture is encircled fixedly, crown can embed the cortical bone layer and reach the stable and antitorque effect of enhancing; In an embodiment described girdle device is adopted nickel-titanium shape memory alloy material, because nickel shape memory alloy has unique memory function to the geometry of self, this memorial alloy is in the time of＜5 ℃, add the external force changeable shape, when temperature rises to a certain particular value (as 37 ℃ of body temperature time), memorial alloy can be returned to original geometry, and produce certain restoring force, utilize this characteristic, this frame-type girdle device can be encircled the pressurization internal fixation to key implementation of more serious comminuted fracture Duan Yanshun, and plasticity is good, and fixed reset is effective, has remedied the fixed deficiency of existing comminuted fracture.
