Description
[technical field]
This utility model relates to the orthopedic nursing utensil of the non-Surgery Treatment of a kind of skeleton and joint, particularly a kind of skoliosis side ejector that cooperates the orthopedic bed of skoliosis patient art front haulage to use.
[background technology]
Spinal column is inherent time-dependent system, the compression stress F that vertebra is suffered
Compression stressWith tension force F
Tension forceKeeping the protruding stability of spinal column physiological lordosis and back (referring to Fig. 1 a), vertebral body and intervertebral disc, it is special to play a part when transmitting compression stress.The physiological lordosis of normal person's spinal column and the protruding F that has determined that spinal column is subjected in back
Compression stressAnd F
Tension forceDirection, and can when spinal column be movable, on the sagittal plane of spinal column, can produce one and order about the outside cross shear F of vertebra
Before(referring to Fig. 1 b), meanwhile the surrounding tissue of spinal column can produce a rightabout cross shear F
AfterTo keep the balance of spinal column.But in the skoliosis patient, because the change of spinal column and structures surrounding thereof, make two shearing force F
BeforeAnd F
AfterDisequilibrium, for reaching once more flat horizontal, just must be by muscle and ligament and little joint and rib deformation, to change F
BeforeAnd F
AfterMoment reach balance once more.Because long term in epispinal unusual power, causes bone to rebuild (referring to Fig. 2), and causes bone malformation, side force drives the top vertebra and departs from center line.In adolescence, health is grown up fast, and the muscle around the spinal column and the tension force of ligament will reduce, and spine balance will further be broken, and side is protruding will the deterioration of carrying out property.Though scoliotic etiology unknown, which kind of cause of disease no matter, it is identical that the final biomechanics of spinal column changes, promptly progressive spinal column is to the side bending.Someone (Perie) etc. utilizes the Computerized three-dimensional Finite Element Method to set up model, relevant position in scoliosis correcting (Boston) brace adds liner, come gaging pressure to find that trunk is in the suffered power maximum of right thorax, left lumbar region and bilateral pelvis by pressure transducer, apply side thrust (referring to Fig. 3) at these positions of skoliosis patient, the long soleplate load of the recessed adnation of the protruding top of side vertebra district vertebral body is reduced, thereby reach the protruding improvement of side or stop progress.
From the mechanics angle: the orthopedic effect after the application of force is produced by moment, moment=arm of force * power.By analysis as can be known, under the constant situation of power, when skoliosis angle＜53 °, the arm of force of side thrust is bigger than the arm of force of longitudinal traction power; When skoliosis angle＞53 °, the arm of force of longitudinal traction power is bigger than the arm of force of side thrust, can confirm that thus side thrust is in orthopedic actual effect and the use value of mate-assist skoliosis patient art front haulage.
[summary of the invention]
Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of mate-assist skoliosis patient art front haulage skoliosis side ejector that orthopedic bed uses is provided.
This utility model has adopted following technical proposal to solve its technical problem: a kind of skoliosis side ejector, comprise support and be installed in penetrator ram in this support, it is characterized in that: described support is made of longitudinal rod and transverse bar, both are fixedly connected into right angle rack, this longitudinal rod one end can be made up-down adjustment after inserting the chuck adapter sleeve, and the fastening screw that passes through on the chuck adapter sleeve is fixed, transverse bar is a hollow form, wherein be equipped with rotatable screw mandrel, a sheathed feed screw nut on this screw mandrel, this feed screw nut is fixedly connected on an end of penetrator ram, the other end connection one of penetrator ram is equipped with the cavity of pressure transducer, one end of described screw mandrel is equipped with the operating grip that is used for rotatable screw mandrel, the outer end of chuck adapter sleeve also be fixedly equipped with one can be on the slide bar of extension table body both sides the fixing fastening seat of buckle.
This utility model can be installed in arbitrarily on the diverse location by bed body both sides slide bar, and can carry out gradual side pushing and withstanding by operating grip, active force is generally 3～6 kilograms, can tolerate situation according to the patient, appropriateness is adjusted, increase side thrust gradually, prevent that the health pressurized is excessive, influence is breathed and other internal organs discomfort.Simultaneously by behind the pushing and withstanding of side, just can reach with less longitudinal traction power and to rescue scoliotic expection traction effect, raising patient comfort level.

[specific embodiment]
The utility model will be further described below in conjunction with embodiment and accompanying drawing.With reference to Fig. 1,
With reference to Fig. 6, Fig. 7 and Fig. 8, this utility model comprises support and is installed in penetrator ram 2 in the support.Described support is made of longitudinal rod 8 and transverse bar 7, and both are fixedly connected into right angle rack.
Can make up-down adjustment after this longitudinal rod 8 inserts chuck adapter sleeve 9, thereby set up the height of a corner bracket, and be fixed by the fastening screw 10 on the chuck adapter sleeve 9.
The outer end of chuck adapter sleeve 9 also is fixedly equipped with a fastening seat 11 that can fixedly be buckled on the extension table 14 both sides slide bars 13, and on fastening seat 11, also be equipped with screw rod and swing handle 12, be used at fastening seat 11 fastening with after extension table body both sides slide bar 13 buckles are connected both.
The other end connection one of this penetrator ram 2 is equipped with the cavity 1 of pressure transducer, its pressure transducer cavity 1 outer wrapping sponge and leather.
One end of described screw mandrel 4 is equipped with the operating grip 6 that is used for rotatable screw mandrel 4, and this operating grip 6 is fixedlyed connected with screw mandrel 4 by screw mandrel pin 5.
This utility model is the special accessories of skoliosis extension table, and 3～4 side estimators of type selecting that can be protruding according to patient's side carry out gradual side pushing and withstanding to scoliotic three place's key points (upper end vertebra, lower end vertebra, top vertebra).
This utility model use side pushing and withstanding carries out skoliosis art front haulage and has tangible advantage and positive effect.Referring to Fig. 4, this is the mechanics sketch map of human body when being subjected to the side pushing and withstanding, acts on the power F of the protruding and protruding top of the waist vertebra of breast
