Abstract
A portable lumbar vertebra tractor is a medical appliance which is used for towing waist. Its structure is that every side of the both sides of a chest around girdle and a pelvic girdle is arranged with a rack and a rotating column rise and fall mechanism which can make them to do relative rise and fall; the mechanism is composed of a rack, a rotational column base and a rotating column which is provided with two circular columns engaged with the rack. Because the portable lumbar vertebra tractor does not need gear wheel, ratchet mechanism and ratch handle, it has simple structure, low cost and light weight, and is convenient to operate, and is easy to popularize and to use. The tractor is adapted for treating various diseases which need treatment of traction, as prolapse of lumbar intervertebral disc, chronic lumbar strain and third lumbar vertebra transverse process syndrome.
Description
This utility model belongs to a kind of medical apparatus and instruments that is used for lumbar traction.
Application number is 88214231.3 portable type lumbar tractors, owing to adopted rack shaft ratchet elevator structure, though the lumbar tractor of the original employing of ratio spiral lifting mechanism is simple in structure, in light weight, use is easy to operate, but it also needs with lifter wheel, ratchet, tightens part in addition such as screw, latch segment, spring, structure still has weak point, and cost, weight are still higher.
The purpose of this utility model is to be the structure of further simplifying the portable type lumbar tractor on the basis of 88214231,3 portable type lumbar tractors at original applying number, and weight reduction reduces cost.
This utility model is realized by following structure, it comprises the chest measurement band, pelvic girdle, its main points are the chest measurement band, the every side in pelvic girdle both sides is equipped with the tooth bar that can make their relative liftings, the Rotational Cylindrical elevating mechanism, tooth bar, the Rotational Cylindrical elevating mechanism is that tooth bar fixedly is housed on chest measurement band or the pelvic girdle, on pelvic girdle or the chest measurement band rotation column base is housed fixedly, tooth bar passes the rotation column base, rotate column base Rotational Cylindrical is housed, Rotational Cylindrical is provided with two cylinders that are meshed with tooth bar, Rotational Cylindrical activity or turning handle fixedly is housed, tooth bar, one of shape of its tooth of tooth bar in the Rotational Cylindrical elevating mechanism is that the inclination angle is 0 °, and promptly its tooth wall of tooth bar is vertical with bottom land.
Above-mentioned portable type lumbar tractor owing to replaced gear with the Rotational Cylindrical that is provided with two cylinders that are meshed with tooth bar, has omitted ratchet mechanism and ratchet handle simultaneously again.So simple in structure, cost is low, and is in light weight, easy to operate, be easy to promote the use of.This traction apparatus is fit to the treatment prolapse of lumbar intervertebral disc, chronic lumbar muscle strain, the multiple disease that needs traction therapeutic such as third lumbar vertebra transverse process syndrome.
1 to 4 represented embodiment describes in further detail this utility model below in conjunction with accompanying drawing.
Accompanying drawing 1: portable type lumbar tractor structural representation.
Accompanying drawing 2: the tooth bar of portable type lumbar tractor, Rotational Cylindrical elevating mechanism sketch map.
Accompanying drawing 3: the left view of the broken section of accompanying drawing 2.
Accompanying drawing 4: the portable type lumbar tractor is worn bundle at patient's sketch map on one's body.
In the accompanying drawing 1 to 4, (1)---chest measurement band, (2)---pelvic girdle, (3)---tooth bar, Rotational Cylindrical elevating mechanism, (4)---tooth bar, (5)---rotate column base, (6)---Rotational Cylindrical, (7) (8)---cylinder, (9)---turning handle.
The embodiment that accompanying drawing 1 to 4 is represented, it comprises chest measurement band (1), pelvic girdle (2), chest measurement band (1), the every side in pelvic girdle (2) both sides are equipped with tooth bar, the Rotational Cylindrical elevating mechanism (3) that can make their relative liftings.Tooth bar, Rotational Cylindrical elevating mechanism (3) are that chest measurement band (1) is gone up stationary rack (4), the inclination angle of tooth bar (4) tooth is 0 °, be that its tooth wall is vertical with bottom land, the fixing dress of pelvic girdle (2) rotates column base (5), tooth bar (4) passes and rotates column base (5), rotate column base (5) Rotational Cylindrical (6) is housed, Rotational Cylindrical (6) is provided with on two cylinder (7) (8) Rotational Cylindrical that are meshed with tooth bar (4) turning handle (9) is housed.
Use operation of the present utility model is such: the patient puts on the portable type lumbar tractor, chest measurement band (1), pelvic girdle (2) are tightened at corresponding position on one's body, rotate turning handle (9) then, Rotational Cylindrical (6) is rotated, the tooth of cylinder (6) (7) pinion rack this moment (3) rotates, the result promotes tooth bar (4) and the past rising of chest measurement band (1), thereby reaches the purpose of traction therapeutic.Unclamp as need, only need turning handle (9) and original rightabout rotation are got final product.
Claims (2)
