Description
Technical field:
This utility model relates generally to the external fixation of fracture frame, relates in particular to the structure of the sole of the foot, phalanx fracture external fixer.
Background technology:
Metatarsal, phalanx fracture are the modal fracture of clinical foot, come the foot fractures front two respectively, injure by a crashing object mainly due to weight, and myotasis is seriously sprained or played due to the thing of boldly confronting a powerful opponent.If can not obtain timely and effective treatment, will leave over long-term foot pain, influence complication and sequela such as foot heavy burden, for the patient brings lifelong misery.Because foot bears a heavy burden for human body and the walking organ, if the pathological changes of foot can not effectively be treated, then can have a strong impact on its function, and these functions of foot are mainly determined by its good anatomical structure, therefore, to the treatment of foot pathological changes, mainly be in order to recover its anatomical structure as far as possible.The main both at home and abroad at present Therapeutic Method that adopts has: 1 pair of fracture without displacement, the shank plaster fixation can be recovered about 4 weeks.2 have the displacement fracture, during the distance of especially fracturing folding end overlapping teratism, adopt shank plaster slab traction and fixation more, if deformity can not be corrected, then adopt open reduction, intersection Kirschner wire internal fixation.But, still there is not effective Therapeutic Method at present to comminuted fracture cripetura displacement person.
The trend of orthopaedics development both at home and abroad is mainly at present: AO school concluded treatment fracture four principles, the i.e. anatomical reduction of fracture end, the strong internal fixation that satisfies local biomechanics needs, noinvasive surgical procedures The Application of Technology and early functional exercise in 1958.At the beginning of the seventies, AO school finds through the clinical practice of decades, emphasizes that merely the viewpoint of biomechanics has many shortcomings, so the viewpoint that develops gradually again based on biology is biological, physiological, the rational osteopathy viewpoint of BO.Its core is for pay attention to the partial blood fortune of protection fracture more when reaching the strong internal fixation of fracture, to guarantee the healing of fracture.The beginning of the nineties, therapy of combining Chinese and Western medicine fracture CO has proposed treatment fracture new ideas, promptly under the cooperation of limited operation, make complicated fracture change Fracture Simple into, adopt non-over-articular external fixation, make patient's early functional exercise, its biomechanical basis is: the fracture healing acceleration pattern of flexible fastening under the condition that keeps the fracture site fine motion.
The method and the principle that generally believe at present ideal treatment fracture both at home and abroad should be able to satisfy following requirement simultaneously: 1. fracture anatomical reduction; 2. secure fixation; 3. rapid healing of fracture, function is recovered synchronously; 4. method is simple, damages for a short time, and economy does not need second operation.Since both at home and abroad to the development trend of fractures for by great opening, major operation to Wicresoftization, the noinvasive development.The research of various external fixators and application are also given birth to regard to application.
The patent No. 02257384.4 discloses a kind of " calcaneus external fixation traction apparatus ".But the structure of the sole of the foot, phalanx fracture external fixer has not yet to see report.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of sole of the foot, phalanx fracture external fixer is provided.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of sole of the foot, phalanx fracture external fixer, include the carrier base (1) of L type, its main feature is to be provided with the fixing card of shank (2) or/and shank fixing band (21) on the column of carrier base (1) (11), is provided with phalanx traction frame (3) at the front end of the base (12) of carrier base (1).The carrier base of its L type (1) but root satisfies the shape need of human foot, the part of posterior leg can design the radian that adapts with organization of human body.
The described sole of the foot, phalanx fracture external fixer are to be provided with in the angle of the carrier base of L type (1) to protect with plate (4), which is provided with ankle fixing band (41).
This utility model is provided with lengthening column (5) on described column (11), the long column (51) that adds that lengthening column (5) is provided with is connected with carrier base (1) by pin-and-hole (13), can regulate the height of column (11), to satisfy different patients' demand.Be provided with the fixing card of shank (2) on the long column (51) or/and shank fixing band (21) adding.
The described column (11) that adds long column (51) and carrier base (1) has angle a, and angle a is 0 degree-10 degree.Can adapt to the variation of different human body ankle and calf.
The phalanx traction frame (3) of the described sole of the foot, phalanx fracture external fixer is the support of L type, and the one end is provided with screw thread (32) and is connected with the screw of base (12), and the other end is provided with traction and fixation tooth (31).Rotate the direction of phalanx traction frame (3), can adapt to the position of different patient's phalanxes.By revolving the length of regulated at will traction frame (3), so that find best haulage, for accurately resetting of fracture lays the foundation.Described phalanx traction frame (3) can be provided with 1-5 as required corresponding to 5 toes.
The base of the sole of the foot, phalanx fracture external fixer (12) can be divided into front portion (121) and rear portion (122), is provided with adjusting device (6) between the two at it, to adapt to the size of different patient's foots.
Described base (12) is a foot bottom shape, and the vola strictness is designed to pattern of outsole according to the physiological characteristics of longitudinal arch of foot and transverse arch of foot, makes patient's foot more comfortable when fixed traction.The fixed via (121) which is provided with foot is the foot fixing band fixedly.
Employed fixing band is the fiber adhesive tape, can regulate elasticity according to patient's lower limb, foot thickness.
The beneficial effects of the utility model are that this support has taken into full account the anatomy and the biomechanics characteristic of normal person's foot, and is reasonable in design.Support is fixed, and determined curative effect, material therefor are engineering plastics, and quality is light, intensity is big, cheap, easy to operate, and is penetrating good to X ray, is convenient to clinical perspective at any time, screening check.Its traction strength can be regulated at any time according to different patients, different state of an illness needs, and the traction dynamics is reliable.
