Description

The lumbar traction treatment instrument

Technical field this utility model relates to the physical therapy device of medical domain, relates in particular to the lumbar traction treatment instrument of treatment prolapse of lumbar intervertebral disc illness.

The treatment prolapse of lumbar intervertebral disc generally adopts the method for traction in the background technology prior art, with the pressure of lax lumbar intervertebral disc, be effective and reset, thereby relief of symptoms reaches the purpose of healing.The extension table volume of the treatment lumbar spondylosis that present hospital is commonly used is bigger, complicated operation; On extension table, patient is tied firmly must to have other people, for example doctor's help, and patient just can carry out traction therapeutic; And must go to hospital.So not only expense is higher, and is also inconvenient.

The summary of the invention the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of lumbar traction treatment instrument is provided, and patient need not go to hospital, also need not other people help, and the own traction that just can finish oneself lies on a bed.

This utility model solves the problems of the technologies described above the technical scheme that is adopted, and designs a kind of lumbar traction treatment instrument, comprises traction belt, symmetrical upper body fixture, handle, pedal, symmetrical outside link, draw-in bar, unidirectional stop mechanism, top sheave, lower sheave and stay cord; Traction belt is fixed on the bottom of draw-in bar, and the upper body fixture is positioned at the top of outside link; Opening is arranged at outside link intermediate hollow and bottom, and draw-in bar inserts into the inner and form with it sliding fit from the lower openings of outside link; Unidirectional stop mechanism is positioned on this outside link, and the part of described unidirectional stop mechanism stretches into this outside link and is pressed on the draw-in bar; Top sheave lays respectively at the lower end of draw-in bar; Lower sheave is separately fixed on the pedal; One end of stay cord is fixed on the two edges of pedal, and the other end is walked around top sheave respectively earlier, walks around lower sheave more respectively, is fixed on the handle together then.

Compare with prior art, advantage of the present utility model is: using method is simple, and patient need not go to hospital, also need not other people help, and the own traction that just can finish oneself lies on a bed; Volume after folding is little, and is easy to carry; Medical expense is low.

The utility model is described in further detail below in conjunction with the most preferred embodiment shown in each accompanying drawing for the specific embodiment.

Lumbar traction treatment instrument as shown in Figure 1 and Figure 2, comprise traction belt 5, symmetrical upper body fixture 18 and 19, handle 10, pedal 8, symmetrical outside link 41 and 42, draw-in bar 48 and 49, unidirectional stop mechanism 31 and 32, top sheave 61 and 62, lower sheave 71 and 72 and stay cord 91,92.Traction belt 5 is fixed on the bottom of draw-in bar 48 and 49, and upper body fixture 18 and 19 lays respectively at the top of outside link 41 and 42.Opening is arranged at outside link 41 and 42 intermediate hollows and bottom, and draw-in bar 48 and 49 inserts into the inner and form with it sliding fit from the lower openings of outside link 41 and 42 respectively.Unidirectional stop mechanism 31 and 32 is positioned on this outside link 41 and 42, and a described unidirectional stop mechanism 31 and a part of 32 stretch into this outside link 41 and 42 and be pressed on draw-in bar 48 and 49.Top sheave 61 and 62 lays respectively at the lower end of draw-in bar 48 and 49; Lower sheave 71 and 72 is separately fixed on the pedal 8; Stay cord 91 and an end of 92 are fixed on the two edges of pedal 8, and the other end is walked around top sheave 61 and 62 respectively earlier, walks around lower sheave 71 and 72 more respectively, is fixed on together on the handle 10 then.As shown in Figure 3, Figure 4, on the draw-in bar 48 and 49 of lumbar traction treatment instrument ratchet bar is arranged, unidirectional stop mechanism 31 and 32 spring ratchet embed described ratchet bar and pin draw-in bar 48 and 49, make it and can not bounce back.Described upper body fixture 18 and 19 comprises axil holder 21,22 respectively, flexible shoulder belt 11,12, and described flexible shoulder belt 11 and 12 is separately fixed on the outside link 41,42.

Patient lies on a bed during use, and at shoulder, axil holder 21,22 is supported on the oxter with flexible shoulder belt 11,12 tie ups, traction belt 5 is tightened waist, light-duty elastomeric objects on the traction belt 5 is close to the lumbar vertebra both sides according to the physiological curve of human body, and both feet are pedaled pedal 8, and both hands catch handle 10 upwards to draw.This moment, stay cord 91,92 drew draw-in bar 48,49 downwards by lower sheave 71,72 on the pedal 8 and the top sheave on the draw-in bar 48,49 61,62.When described draw-in bar 48,49 extended downwards, unidirectional stop mechanism 31,32 made it and can not bounce back immediately with the locking of the sawtooth on the draw-in bar 48,49.Because draw-in bar 48,49 bottoms and traction belt 5 closely are stitched together, when draw-in bar 48,49 extended downwards, lumbar vertebra had also just obtained traction.Simultaneously, the light-duty elastomeric objects that is sewn in the traction belt 5 also plays massage effect to the lumbar vertebra both sides.As shown in Figure 5, in this utility model, what described light-duty elastomeric objects adopted is spring steel plate.

Characteristics of the present utility model are by the lower sheave on top sheave on the draw-in bar 48,49 61,62 and the pedal 8 71,72, the power of drawing on patient's both hands to be converted into the power that draw-in bar 48,49 is drawn downwards.Like this, patient lies on a bed, and just can finish traction to oneself like a cork by the action of drawing on the own both hands.

Described lumbar traction treatment instrument can be used for treating multiple waist diseases such as waist lower limb ache, lumbar muscle strain, prolapse of lumbar intervertebral disc, sciatica.
