But these clamping plate can not reach for different individual patients dissects the state of plasticity, although and have the bandage of antibiotic skin-care, the most position of clamping plate is airtight and air-locked, easily causes the position chafing of the Boards wall of patient.
Utility model content
The purpose of this utility model is to provide a kind of fixing fracture more comfortable stable, the dissection type fracture small clamping plate outer external fixator of structure optimization, light, good permeability.
The technical solution adopted in the utility model is as follows:
A kind of dissection type fracture small clamping plate outer external fixator, comprise at least one piece of clamping plate adapted with limb fracture position, the curved surface of described clamping plate is the curved surface corresponding with body surface anatomic form obtained by CT three-dimensional reconstruction image, described clamping plate are provided with multiple hollow-out parts, described clamping plate comprise first end, the second end, the pars intermedia that is connected with the second end with first end, and the average fretwork area of the hollow-out parts of described first end is less than the average fretwork area of the hollow-out parts at other positions of clamping plate.
In above-mentioned dissection type fracture small clamping plate outer external fixator, the length of described first end is 0.1 ~ 0.5 times of whole clamping plate length.
Preferably, the length of described first end is 0.2 ~ 0.4 times of whole clamping plate length.
In above-mentioned dissection type fracture small clamping plate outer external fixator, the width of described first end is 0.6 ~ 0.9 times of the second end width.
Preferably, the width of described first end is 0.7 ~ 0.85 times of the second end width.
In above-mentioned dissection type fracture small clamping plate outer external fixator, the hollow-out parts of the pars intermedia of described clamping plate is strip along its length.
In above-mentioned dissection type fracture small clamping plate outer external fixator, the average fretwork area of the hollow-out parts of the pars intermedia of described clamping plate is greater than the average fretwork area of the hollow-out parts of the second end.
In above-mentioned dissection type fracture small clamping plate outer external fixator, described first end, the second end and pars intermedia are network structure.
Preferably, first end is arranged in unordered mode by the hollow-out parts of the shapes such as circle, triangle, tetragon, pentagon, hexagon, improves cancellated stability.
In above-mentioned dissection type fracture small clamping plate outer external fixator, the material of described clamping plate is green bio environmental protection poly-lactic acid material (PLA), described clamping plate are the dissection arc-shaped curved surface based on CT body surface three-dimensional reconstruction, also comprise the binder of strap.
This utility model adopts the cause of poly-lactic acid material to be, along with the development of 3D printing technique, this product can according to the anatomical structure shape of CT scan device scan needs of patients fixed position, design the clamping plate external fixer being more applicable to body surface curved surface, then by 3D printing technique, take poly-lactic acid material as raw material, the dissection type fracture small clamping plate outer external fixator that printing note utility model proposes, its portable construction, recovery of can degrading.
By arranging large-scale hollow-out parts, this utility model ensures that this dissection type fracture small clamping plate outer external fixator has good permeability.
Further, the average fretwork area arranging the hollow-out parts of first end is less than the average fretwork area of the hollow-out parts at other positions of clamping plate, in use, first end is general near fracture site, such as: colles is fractured, use two pieces or four pieces of Boards wall fracture sites, its fracture site is that forearm is near wrist place, by first end is arranged on wrist place, the contact area of first end and limbs can be improved, improve the stability of clamping plate and extremity, what is more important, wrist is as the more position of an activity, its large-area contact area prevents fracture site from misplacing, improve fixing stability.Certainly, be not that this utility model is only applicable to colles fracture, still can apply in other fracture, it uses and installs principle with method with consistent in colles fractures.
Further, the hollow-out parts of the pars intermedia of clamping plate is strip along its length and the maximum weight that can effectively reduce clamping plate of area of the preferred hollow-out parts of pars intermedia, saves material, ensures that its structure has certain stability by network structure.And what is more important, its permeability is good, can go out perspiration etc. by Quick diffusing.
Further, Material selec-tion of the present utility model goes for 3D printing technique, improves individual adaptability.
