Abstract
The invention provides a medical traction apparatus in the field of medical instruments. The medical traction apparatus is characterized by being of a floating-type traction apparatus through combining the lever principle and a ratchet-type rope tightener. The medical traction apparatus comprises a support shell, and the ratchet-type rope tightener and a floating lever device are arranged in the support shell. The rope tightener consists of a hand wheel, a ratchet, a rope tightening wheel and a check pawl; the floating lever device consists of a combined moment arm, a fixed pinch point pin shaft, a fulcrum movable pulley slider, a readjustable hand wheel, a chain wheel combination, a fine-tuning hand wheel, a weight, a linked steel wire rope and the like. The medical traction apparatus is easily linked on devices such as a chair, a bed and a frame so as to perform traction, is a medical traction apparatus which is light and effort-saving, can be automatically regulated, is intuitive and constantly stable in traction force and is safe and practical.
Description
The present invention relates to a kind of medical traction apparatus.
The traction apparatus that is applied to the medical skill aspect at present mainly contains following several kinds of forms and constitutes: though they can both play certain draw, still there are many shortcomings in taenidium rod-type, simple ratchet tight rope formula, springs formula etc.Such as the traction apparatus of taenidium rod-type with simple ratchet tight rope formula, when drawing for physical activity position (like cervical vertebra, lumbar vertebra), nominal value of thrust usually can change significantly because of the biomechanics tensile force of human body and devalue; The traction apparatus of springs formula equally also can obviously increase nominal value of thrust on foot because of the biomechanics tensile force change of human body or become zero.Therefore have influence on the traction therapeutic effect.
The purpose of this invention is to provide a kind of improved medical traction apparatus; It can prevent to cause in the hauling distance limit imbalance of rated drawbar pull effectively; The size that can show rated drawbar pull again intuitively; Can also in traction state, regulate pull strength on demand at any time by user oneself, and it is permanent steady to remain value of thrust.
The objective of the invention is to realize like this: use Archimedes's lever principle and organically combine into a kind of medical traction apparatus with ratchet-type tight rope device.This device external form is a bracket shell, and its inside is provided with ratchet-type euphroe, active type lever device, outlet turning fixed pulley and contact steel wire rope.
(1) bracket shell is at first fixing used for internal structure, and secondly bedplate is provided with preformed hole and inserts and carve side plate, conveniently with equipment combinations such as chair, bed, framves.
(2) the ratchet-type euphroe is in same rotating shaft, to be equipped with handwheel, ratchet, bearing up pulley and corresponding check pawl successively.
(3) floating type leverage is provided with the combination arm of force, is provided with successively in a fixing sled point tip axle, portable fulcrum slide block, the slide block fulcrum movable pulley is housed, slide block connects with the readjustment handwheel that sled point is held, and the readjustment handwheel is provided with weight and identifies; The outer arm of force end inside of fulcrum is provided with chain wheel set, and chain wheel set is equipped with trimming hand wheel, chain drum, and chain, standard test weight are fixed on the chain, and the weight sign is arranged on the arm of force corresponding with counterweight.
(4) contact steel wire rope one end is fixed on the bearing up pulley, passes the fulcrum movable pulley in the arm of force end fulcrum slide block successively, passes the fixed pulley that turns to of bracket shell top front end then, stretches out with the traction object to connect.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is that the master of a kind of medical traction apparatus of proposition according to the present invention looks sketch map.
Fig. 2 is the schematic top plan view of a kind of medical traction apparatus of proposition according to the present invention.
Specify the details and the working condition of the concrete device that proposes according to the present invention below in conjunction with accompanying drawing:
Mainly comprise bracket shell (1), gusset piece (2), ratchet-type euphroe (3), floating type leverage (4) and contact steel wire rope formations such as (5) like Fig. 1, a kind of medical traction apparatus shown in Figure 2.
Like Fig. 1, shown in Figure 2, ratchet-type euphroe (3) is positioned at bracket shell (1) upper back, in same rotating shaft, is equipped with handwheel (6), ratchet (7), bearing up pulley (8) and corresponding check pawl (9) successively; Floating type leverage (4) is positioned at bracket shell (1) middle and lower part; It is provided with the combination arm of force (10), is provided with successively to be equipped with in a fixing sled point tip axle (11), adjustable portable fulcrum slide block (12), the slide block (12) that fulcrum movable pulley (13), slide block connect readjustment handwheel (14), readjustment handwheel (14) dish is provided with the weight sign; The combination arm of force (10) other end is provided with the sprocket wheel combination, and chain wheel set attaches together be furnished with trimming hand wheel (15), chain drum (16), chain (17), is fixed with standard test weight (18) on the chain, and the combination arm of force (10) corresponding with counterweight (18) is provided with weight and identifies (19).
Like Fig. 1, shown in Figure 2; Contact steel wire rope (5) one ends are fastened on the bearing up pulley (8); Pass the fulcrum movable pulley (13) in the combination arm of force (10) end fulcrum slide block (12) successively, that passes the preceding upper end of bracket shell (1) then turns to fixed pulley (20), stretches out and draws object and connect.
During use, at first level of the present invention is connected on the equipment such as chair, bed, frame, will gets in touch steel wire rope (5) and connect with required traction object.When implementing first kind of scheme, counterweight (18) or readjustment handwheel (14) are transferred to predetermined indicated weight, compress check pawl (9) after, the handwheel (6) of rotating ratchet formula euphroe (3), make the combination arm of force (10) rise to level, promptly realized predetermined pull strength.When traction finishes, unclamp check pawl (9) and can remove traction state.
When implementing second kind of scheme; Only need at (promptly in traction realization state) on the basis of implementing first kind of scheme; Readjustment handwheel (14) or trimming hand wheel (15) on the difference rotation combination arm of force (10); Counterweight (18) or fulcrum slide block (12) are moved forward and backward, promptly changed (power X power arm two resistance X resistance arms) lever balance force rate, obtain new rated drawbar pull value on demand.If the traction object is telescopic variation slightly, the combination arm of force (10) can fluctuate in limit range, and the instantaneous acquisition dynamic compensation of pull strength is also kept permanent steady.The way of avoiding pull strength to transfinite is grasped the elasticity of tight rope handwheel (6) exactly, lets the combination arm of force (10) remain at level, notices that this point is not so difficult, because the combination arm of force (10) is very showy directly perceived.
The present invention has used lever balance theories such as wheel shaft, pulley dexterously, so operate freely lightly, can extensively satisfy medical treatment traction and otherwise needs.
