Description
Technical field
This utility model relates to a kind of multi-direction adjustable chi radius external fixer, belongs to medical instruments field, cooperates spicule treatment forearm fracture, metacarpal fracture, wrist fracture and strides wrist fracture and the comminuted fracture disease.
Background technology
The comminuted unstable fracture Therapeutic Method of chi distal radius is more, and traditional manual reduction Gypsum Fibrosum is fixing easily to be occured mobilely again, and band nail Gypsum Fibrosum is fixed, fixing and haplotomia interior shortcomings and the limitation of also existing such as fixing that reset through Intradermal.
The radius hypomere is scaled to distal radius, the distal radius cross section is square, spongy bone cortex as thin as a wafer, be unfavorable for outer fixedly thread a needle and screw control, palmar is smooth to have pronator quadratus to adhere to, dorsal part has tuber of radius and three tendon ditches, the latter has extensor tendon to pass through, and is unfavorable for laying inside-fixture, and malreduction can damage tendon, the outside is tuber of radius, have two ditches also to pass through for tendon, inboard arc-shaped concave and capitulum ulnae form the joint, the radius far-end fracture damage that occurs together easily, dislocation, normal distal radius has articular surface to have incline 10 °～15 ° and chi of the palm to incline 20 °～25 °, processus styloideus radii has many tendons to pass through than the long 1～1.5cm of ulna belemnoid before and after the radius, and the median nerve traveling is in the canalis carpi of palmar, the ramus superficialis traveling of radial nerve is near processus styloideus radii, and the ulna dorsal part is without vital tissue herein.
Radius far-end fracture comprises the Colles fracture, Smith fracture and Barton fracture, the Colles fracture is common clinically, with in, senile fracture is many, the Smith fracture is the same with the Colles fracture, majority can adopt manual reduction, and Gypsum Fibrosum or clamping plate External fixation result are satisfied, but clinical fixed solution is stiff much except rear interphalangeal joint, Barlon fractures but sclerite is less, manual reduction difficulty often needs operative reduction, and this fracture needs special plate fixedly the time in implementing, sometimes it is unreliable to fix, bone is fixed with some superiority outward, then shows as the distal radius epiphyseal fracture the child, and manual reduction is easy, but child's movability, again displacement occurs easily sometimes, if adopt bone fixing outward, at the distal bone piece with thin fixing without screw thread half pin, do not injure epiphysis, or trans-articular fixedly is good selection.
A large amount of studies have shown that, the rear residual deformity of radius far-end fracture healing and dysfunction in the future exist direct relation, as seen, good anatomy relationship is the basis of keeping hands, carpal joint and forearm normal function, in treatment of distal radius fracture, make every effort to recover its original normal anatomical relationship and be each orthopedist must pay attention to, the easy concurrent dislocation of distal radioulnar joint of radius far-end fracture, should note not ignoring, prevent that delay treatment from causing sequela, its fixing fixing means that there is no at present.
Summary of the invention

Soket head cap screw (7) left end has interior hexagonal hole, being convenient to apparatus holds and gets, soket head cap screw (7) the adjustable clamp needle body (9) of folder needle assembly (1) upper end, when it does the axially parallel motion along support body (2), regulate and lock, the soket head cap screw (7) of folder needle assembly (1) lower end links together catch (10), folder pin piece (11), folder needle body (9), this folder pin place can 360 ° of rotations, regulate spicule to final locking, realize the compound mode of multiple angles folder pin.
After external fixer locking, can carry out micro-positioning regulators to external fixer by soket head cap screw (7), realize pressurization, the function that resets.
Linked together as the joint by spheroid (5) in the middle of two support bodys (2) of multi-direction adjustable chi radius external fixer, make two support bodys (2) do arbitrarily angled motion and rotation, realize function multidirectional, that multi-angle is regulated.
The motion of multi-direction adjustable chi radius external fixer and rotate and to be fixed removable the simple and easy fixing of long bone of doing of the support body on both sides (2) on can be at an arbitrary position.
This utility model cooperates the diseases such as spicule treatment forearm fracture, metacarpal fracture, wrist fracture, can realize the multiple combination mode, select during for operation, and the operation technique specification requirement is relatively low, can guarantee trauma fracture reset and fixing, and the treatment later stage can according to circumstances make the fracture end motorization, accelerating bone healing, can't adopt in the internal fixation treatment situation, this utility model both can make fracture end reliably be fixed, and can be convenient to again the reparation for the treatment of of wounds and later stage.
By the diagnose medical conditions such as CT or X-ray before the art, determine fracture, implement operation: determine fixed-segment, surgery location, implement boring, be screwed into spicule, after installing, spicule reserves certain adjusting length, be convenient to external fixer and regulate pressurization, external fixer is fixed on the spicule regulates at last, using the same method is screwed into other spicules, external fixer is installed, is adjusted external fixer to requirements of operation.
Multi-direction adjustable chi radius external fixer can arbitrarily be fixed according to patient with bone fracture, recovers the fracture reduction of patient with bone fracture, and can regulate in the middle for the treatment of.
Multi-direction adjustable chi radius external fixer is implemented fixing under the cooperation of spicule, has advantage simple in structure, easy to operate, cheap, safe and reliable, portable, advanced design, it is simple that it uses apparatus, and the operation technique specification requirement is relatively low, is suitable for Orthopedic Clinical and applies.
