In the present invention, using front human body back to extension table when, extension table near one end of human body for front and away from human body One end be after.

Lathe bed 2 extends in front and rear direction, and its front portion is located between two front leg struts 11, and rear portion is located at two rear support legs Between 12.The front portion of lathe bed 2 is passed through rotating shaft 21 and is connected with front leg strut 11 rotation of both sides, and rear portion is then provided with adjusting rod 22, adjusts The two ends of bar 22 respectively penetrate the rear support leg 12 of both sides, and the top of two rear support legs 12 symmetrically offers multiple longitudinally spaced rows The adjustment hole 121 of row, is coordinated with adjusting rod 22, thus, it is possible to be inserted in different adjustment holes 121 by adjusting rod 22 adjust Section lathe bed 2 and the angle of inclination of horizontal direction.

The rear end of lathe bed 2 is respectively provided on two sides with support 23, is provided with crossbeam 24 between support 23, and crossbeam 24 lower surface is provided with fixed Pulley 25, for through traction belt.The both sides of lathe bed 2 are provided with handrail 26, are available for patient and grip in traction, to keep and to lead Draw a relative position to fix.

Referring to Fig. 3, be the curve of lathe bed 2 upper surface, this curve include tangent successively and the first circular arc ab of rounding off, Second circular arc bc, three-arc cd, wherein, starting point a of the first circular arc ab is the lowest part of above-mentioned three sections of circular arcs, the first circular arc Ab is in convex, and corresponding to the buttockss waist of patient, the first circular arc ab is more gentle, is more applied to the heavier patient of the state of an illness, and a point continues Extend forwardly to reach the front end e point (being also minimum point) of upper surface；The intersection of the first circular arc ab and the second circular arc bc, Yi Jiyu The adjacent region in this intersection corresponds to the waist lordosis of patient；Second circular arc bc is in recessed, corresponding to the back of patient；The The intersection of two circular arc bc and three-arc cd and the region adjacent with this intersection correspond to the cervical region of patient；And the 3rd Circular arc cd is in then convex, corresponding to the head of patient again；The rear end f point of the terminal of three-arc cd to lathe bed 2 is also extended with one Section, because it does not play direct effect to distraction procedure, therefore does not limit specific shape, by three-arc cd terminal and lathe bed 2 Rear end connects.Physiological curve (buttocks, the waist of human body from the foregoing, it will be observed that the curve of this lathe bed 2 upper surface can preferably be fitted Portion, back and cervical region), thus reaching preferable traction effect.

In the present invention, it is preferred to, the length of the first circular arc ab is 25～30cm, and radius is 40～50cm, the second circular arc The length of bc is 39～45cm, and radius is 165～175cm, and the length of three-arc cd is 10～16cm, radius is 150～ 160cm, is suitable for the patient of different building shape.

The operation principle of the extension table of the present invention and process are as follows: during traction, patient back, towards lathe bed 2, lies supine upon bed On body 2, both feet must be liftoff, starts to fit with lathe bed 2 upper surface from buttocks, and traction belt is fixed under rib, chest or oxter Fixing with crossbeam 24 afterwards, and winding extends downwardly after crossing fixed pulley 25 after separately having a traction belt fixing head, can be in this traction Strap end portion arranges traction weight, and leg can also increase pull strength to increase gravity by bondage weight.

Because the curve of lathe bed 2 upper surface can be fitted the physiological curve of human body, therefore, can play in traction dual Effect: 1, draw, the lathe bed 2 of inclination makes to carry out curve traction using the natural gravity of human body during traction, and bed The force position of body 2 upper surface all acts on the position of needs, plays preferable traction effect to lumbar vertebra, cervical vertebra；2nd, the work breaking With this refers to that lumbar vertebra has been acted on one is the active force that all waist disease patients are required for towards the anterior power of human body, ginseng See Fig. 4, because lumbar vertebra has individual physiology lordosis, in the presence of traction force f, vertebra 31 is stretched by both direction up and down, lumbar vertebra Intrinsic pressure being gradually reduced of vertebra of anterior intervertebral disc and fibrous ring 32 and recover, and in the presence of stubborn power t, lumbar vertebra rear portion adjacent Joint capsule and ligament 33 also can be backed down and be widened spacing, so that the degree recovered of intervertebral disc and fibrous ring 32 and joint The degree of capsule and ligament 33 recovery reaches suitable ratio, returns to normal scope as far as possible, plays completely whole bone effect. And in existing extension table, but do not reach such effect, due to the curve of vertebra of can not fitting completely, therefore can not apply , so that lumbar vertebra (cervical vertebra) is only pulled power, joint capsule and ligament 33 pull strength are excessive for the optimal proportion active force leading and breaking, and Then pull strength is too small for intervertebral disc and fibrous ring 32.

The lathe bed 2 of the present invention can also adjust the angle of inclination, thus adapting to the various stages of conditions of patients.When the state of an illness relatively During weight, adjusting rod 22 is inserted in the adjustment hole 121 of the top, lathe bed 2 angle of inclination reaches 40～55 degree, and vertebra receives , based on drawing, stubborn power is less for power, gradually turns angle down as sb.'s illness took a favorable turn；When state of an illness convalescent period, adjusting rod 22 is inserted Enter in the adjustment hole 121 of bottom, lathe bed 2 angle of inclination reaches 15～20 degree, based on stubborn power, pull strength is less.At this During regulation, with lathe bed 2 around the shaft 21 rotation, the strong point b point height of corresponding waist is between 100～106cm Change.
