Abstract
The invention belongs to the field of orthopedics medical apparatuses, and discloses a self-locking fracture reduction fixing apparatus, which comprises a fixed link (6) and a telescopic fixed sleeve (9) which is sleeved on the fixed link (6), wherein the a left end fixing apparatus which consists of a screw fixation clamp box body (1) is installed at the left end of the fixed link (6). The self-locking fracture reduction fixing apparatus is characterized in that: a worm (2) and a worm gear (3) which laterally move and a worm (5) and a worm gear (4) which longitudinally move are arranged above the screw fixation clamp box body (1), a right end fixing apparatus which consists of a screw fixation clamp box body (12) is installed at the right end of the telescopic fixed sleeve (9), and a worm gear (10) and a worm (11) which laterally move and a worm (7) and a worm gear (8) which longitudinally move are arranged above the screw fixation clamp box body (12); and the mutual matching of the worms and the worm gears is utilized to form the deceleration and self locking characteristics, so the adjustment of four free angles and eight directions can be actively carried out within a wider scope. The invention has the advantages of simple structure, convenience in adjustment, easiness in management and maintenance and the like.
Description
Technical field
The invention belongs to medical instruments field, relate to orthopaedics and have the initiatively external holder device of single armed of multi-direction adjusting fracture in clinical, especially can initiatively automatically lock the position in the adjustment process continuously.
Technical background
At present, the adjustable body support arm of treatment fracture has multiple, it can be divided into passive adjustable type and active adjustment formula by its regulative mode, can only be behind the release fixed part when passive adjustable type is regulated, just regulate fracture when the exterior fixation bracket fixation is removed fully, retighten by the new position of fracture again; The active adjustment formula can drive the variation that length or angle take place fracture by the associated components of regulating support, thereby reaches the purpose of regulating fracture.The representative initiatively support of using in clinical of multi-direction adjusting is to carry out the support that complex combination forms by a large amount of various parts.The ring type support requires many pieces of locking pins to pass from different perspectives to greatest extent to obtain maximum fixation around the backbone, therefore it is abundant or importantly know the neural position of pipe that locking pin often need pass muscle, thereby influence the movable even damage vital tissue structure of limb function, and because of support all or part of around limbs, bring great inconvenience to patient, shortcomings such as clinical middle orthopedist is often loaded down with trivial details because of the support installation, adjusting complexity, management difficulty is big, complication is many are abandoned using.
Summary of the invention
For solving above-mentioned technical deficiency, the invention provides a kind of external holder device, this device is simple single armed external fixer form, can initiatively carry out four free angles in a big way, the adjusting of eight directions, and in adjustment process, can automatically lock adjusting position, have fracture positive return and fixed function concurrently.The technical scheme that the present invention solves is: a kind of self-locking type fracture reduction fixator, be provided with fixed bar (6) and be enclosed within fixed bar (6) and go up telescopic fixed sleeving (9), left end at fixed bar (6) is installed the left end holder of being made up of screw fixation clamp casing (1), it is characterized in that, the top of screw fixation clamp casing (1) is provided with worm screw (2) and the worm gear (3) that laterally moves, worm screw that vertically moves (5) and worm gear (4), right-hand member at telescopic fixed sleeving (9) is installed the right-hand member holder of being made up of screw static housing (12), be provided with worm gear (10) and worm screw (11), the worm screw that vertically moves (7) and the worm gear (8) that laterally moves in the top of screw fixation clamp casing (12).
Description of drawings
Fig. 1 is a structural representation of the present invention.
The present invention is specifically described by embodiment below in conjunction with accompanying drawing.
The specific embodiment
The self-locking type fracture reduction fixator is provided with fixed bar 6 and is enclosed within telescopic fixed sleeving 9 on the fixed bar 6, left end at fixed bar 6 is installed the left end holder of being made up of screw fixation clamp casing 1, the top of screw fixation clamp casing 1 is provided with worm screw 2 and the worm gear 3 that laterally moves, worm screw 5 that vertically moves and worm gear 4, right-hand member at telescopic fixed sleeving 9 is installed the right-hand member holder of being made up of screw static housing 12, above screw fixation clamp casing 12, be provided with the worm gear 10 and the worm screw 11 of laterally moving, worm screw 7 that vertically moves and worm gear 8.Deceleration, the latching characteristics that utilizes worm gear and worm screw to complement each other to form reaches position auto-lock function in continuous active adjustment of entire bracket device and the adjustment process.
The present invention has four free angles that carry out fracture end that can be initiatively, the adjusting in a big way of eight directions, satisfy the requirement of the reduction of the fracture, and can in the back setting phase that resets, fixedly secure, its have simple in structure, easy to adjust, be easy to management and safeguard, and significantly reduced advantage such as complication.
