Abstract
The invention relates to a sit-down lumbar tractor, which takes two support sleeves as the main body and comprises an elevator armpit supporting bracket, an upper nut of waistband, a manual loading mechanism, a lower sleeve of waistband, a base and a waistband. The lumbar tractor takes the resultant force of the body deadweight and the manual load as the traction force and all the mechanical displacements along the traction force direction are achieved by screw thread transmission. The sit-down lumbar tractor has the advantages of compact and simple structure, easy and convenient force application; therefore, the lumbar tractor is suitable for the patient suffering from lumbar diseases to use during trip and at home.
Description
Technical field
The present invention relates to a kind of medical treatment device that is used for the lumbar spondylosis treatment, particularly a kind of Sitz type lumbar vertebra tractor.
Background technology
The apparatus that is used for the lumbar spondylosis traction therapeutic at present has extension table and small-sized traction apparatus, and the power resources of its pull strength and the difference of transfer mode make the structure difference of lumbar traction device.The power resources of traction apparatus can be manual, electronic, pneumatic and the hydraulic pressure various ways, and wherein electronic, pneumatic and three kinds of modes of hydraulic pressure are mainly used in extension table, and small-sized traction apparatus mainly adopts manual mode.The transmission method of pull strength has the wire rope transfers pull strength by train, gear mechanism transmitting tractive power, cylinder transmitting tractive power.There is the defective that structure is not compact, mechanism is complicated, the transmission of pull strength sudden change reaches manually reinforcing difficulty in these modes.
Summary of the invention
It is simple to the purpose of this invention is to provide a kind of compact conformation, and the application of force is simply light, and is convenient, flexible, is fit to the Sitz type lumbar vertebra tractor that the patient uses.
The object of the present invention is achieved like this: a kind of Sitz type lumbar vertebra tractor, comprise stop sleeve 3 with internal and external threads, axillary fossa carriage 1, last waistband nut 4, handle force application mechanism 8, following sleeve 11 with a tight waist and base 12, axillary fossa carriage 1 is connected with the female thread of stop sleeve 3 upper ends, last waistband nut 4 is connected with stop sleeve 3 upper external screw threads, handle force application mechanism 8 is threaded with stop sleeve 3 lower ends, following waistband sleeve 11 and handle force application mechanism 8 screw fixed connections, base 12 is connected with stop sleeve 3 lower end female threads.Manual force mechanism 8 is made up of handle and ratchet mechanism, and ratchet 6 and ratchet 7 profiles of tooth are trapezoidal.
The mechanical displacement of its pull strength direction of Sitz type lumbar vertebra tractor of the present invention all adopts the screw thread transmission, and compact conformation is simple.With body weight and manually the auxiliary application of force make a concerted effort make the application of force simply light, convenient, flexible as the pull strength of traction apparatus, be well suited for the patient and reach in the family on the road and use.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the partial structurtes sketch map of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
Wherein, Fig. 1 holds a concurrent post Figure of abstract.
Among the figure: 1, axillary fossa carriage, 2, clamp nut, 3, stop sleeve, 4, last nut with a tight waist, 5, the ratchet lid, 6, ratchet, 7, ratchet, 8, the handle force application mechanism, 9, spring, 10, pin handle, 11, following sleeve with a tight waist, 12, base, 13, alignment pin, 14, go up waistband, 15, waistband down.
The specific embodiment
As shown in Figure 1, mechanism is placed on the stool, regulate axillary fossa carriage 1 screw thread, make length overall to appropriate length, thereby warrantor's buttocks and stool face have a suitable unsettled distance, the auxiliary clamp nut 2 of reuse is fixed the axillary fossa carriage, the length that nut 4 with a tight waist changes in the adjusting makes waistband 15 to the human body correct position, patient's frame is on carriage then, and fasten waistband 15, the TBW of human body is distributed on axillary fossa carriage 1 and the last waistband on 14, has avoided power is too concentrated on the axillary fossa carriage 1, increased comfort.Fasten down waistband 15 then, the handle of pulling on the haulage gear reduces the distance between waistband 15 and stool face, thereby produces certain additional pulling force.Reach therapeutic effect.
As shown in Figure 2, Sitz type lumbar vertebra tractor has axillary fossa carriage 1, stop sleeve 3, upward nut 4 with a tight waist and the handle force application mechanism 8 be made up of ratchet mechanism.Axillary fossa carriage 1 is connected and can realizes lifting according to needs with stop sleeve 3 upper internal threaded, by clamp nut 2 locking axillary fossa carriages 1, the last waistband 14 of traction apparatus and following waistband 15 are separately fixed on waistband nut 4 and the following sleeve 11 with a tight waist, last waistband nut 4 can be in stop sleeve turn about in the of 3, the manual force mechanism 8 of sleeve 11 with a tight waist and ratchet 6 compositions is screwed connection down, when waistband 15 moves up and down under requiring, circumferentially pull handle, when returning original position, handle needs pin handle 10 is pulled out, spring 9 compressions, ratchet 7 breaks away from ratchet 6, and handle is return ratchet not to be changeed, unclamp pin handle 10, ratchet 7 mesh ratchet gears are circumferentially pulled handle, and following waistband 15 moves up and down, apply or reduce extra traction, base 12 is as the bottom supporting of stop sleeve 4.
As shown in Figure 3, be the handle force application mechanism 8 that trapezoid ratchet 6 and ratchet 7 are formed by profile of tooth, ratchet 6 and ratchet 7 engagements, pull handle, ratchet 6 and the transmission of stop sleeve screw thread are pulled out pin handle 10, pull handle, ratchet 6 is not done transmission, and alignment pin 13 prevents that ratchet 7 from rotating.
With two stop sleevees 3 as main body, there is positive and negative thread segment at the two ends of stop sleeve 3, there is the female thread of certain-length the sleeve upper end, axillary fossa carriage 1 is connected and can realizes lifting according to needs with stop sleeve 3 upper internal threaded, by auxiliary clamp nut 2 locking axillary fossa carriages 1, determine the length on stop sleeve 3, the last waistband 14 of traction apparatus and following waistband 15 are separately fixed on waistband nut 4 and the following waistband sleeve 11, directly regulate and go up waistband nut 4, can move up and down the position of waistband 14 on stop sleeve 3, following waistband sleeve 11 and manual force machine 8 structure screw fixed connections of being made up of ratchet 6 and ratchet 7 are by waistband 15 liftings under ratchet 6 female threads and the stop sleeve 3 externally threaded turn adjustment.Base 12 and the direct screw threads for fastening of stop sleeve 3 endoporus.
Earlier traction apparatus is placed on the stool during use, the patient regulates axillary fossa carriage 1 screw thread according to people's concrete conditions in the establishment of a specific crime, make two oxters to the stool face in proper height, thereby a suitable unsettled distance is arranged between warrantor's buttocks and stool face, the auxiliary clamp nut 2 of reuse is fixing with axillary fossa carriage 1, waistband nut 4 changes supreme waistband 14 distances of stool face to the human body correct position in the adjusting, patient's frame is on carriage then, human body is unsettled, at first rely on the pulling force of body weight, lumbar spine to human body produces certain stretching action, and fasten waistband 14, the TBW of human body is distributed on axillary fossa carriage 1 and the last waistband 14, has avoided power is too concentrated on the axillary fossa carriage 1, increased comfort.Tighten down belt 15 then, pull the application of force handle distance between waistband 15 and stool face is reduced, thereby produce certain additional pulling force, reach the effect of light treatment lumbar spondylosis.
