The portable lumbar vertebra tractor is characterized in that both sides of the chest around girdle and the pelvic girdle are respectively provided with a rack shaft ratchet wheel lifting mechanism which can make the chest around girdle and the pelvic girdle to lift and is composed of a rack shaft apparatus and a gear wheel ratchet wheel apparatus. The tractor not only changes the of a traditional bed, and can be portable, and can be used at sitting, standing and lying, but also is convenient for patients to operate by themselves. The element is easy to process. The tractor has small volume and light weight. The utility model is adapted for treating various diseases which need treatment of traction, such as prolapse of lumbar intervertebral disc, chronic lumbar strain, third lumbar vertebra transverse process syndrome, etc.
Description
This utility model is a kind of medical apparatus and instruments that is used for lumbar traction.
Existing more advanced lumbar tractor, though solved the problem of carrying, the spiral lifting structure is adopted in control chest measurement band, pelvic girdle lifting, this structure makes troubles for patient self descending operation, and the lifting of spiral lifting structure is slow, and volume is big, Heavy Weight.
The purpose of this utility model is in order to provide a kind of patient self descending operation convenient, the member handling ease, and volume is little, lightweight portable type lumbar tractor.
The portable type lumbar tractor is realized by following structure, it comprises the chest measurement band, pelvic girdle, it is characterized in that at the chest measurement band, the pelvic girdle both sides respectively are equipped with and can be made the chest measurement band, the rack shaft ratchet elevator structure of pelvic girdle lifting, rack shaft ratchet elevator structure is by the rack shaft device, the gear ratchet device is formed, rack shaft, one of structure of gear ratchet device is that the tooth bar axle bed is equipped with in chest measurement band both sides, the rack shaft block set is equipped with in the pelvic girdle both sides, fixing a pogo barrel on the rack shaft block set, the rack shaft block set becomes stairstepping with the endoporus that pogo barrel is formed, this endoporus has outer wall and endoporus all to become step-like tooth bar axle sleeve movingly, tooth bar axle sleeve endoporus has rack shaft movingly, one end of rack shaft is fixed on the tooth bar axle bed, the lower end stationary fit of pogo barrel has end cap, the end cap endoporus is equipped with the spring adjusting nut, in pogo barrel, around rack shaft spring is housed with tooth bar axle sleeve imperial palace bore portion, the gear ratchet device is in the stationary fit of tooth bar axle sleeve outer wall pinion stand to be arranged, the lifter wheel that is meshed with the tooth bar of rack shaft is housed in the pinion stand, be equipped with on the lifter wheel and its ratchet that rotates synchronously, be set with the ratchet handle on the ratchet, the ratchet handle can unload when not using, and radially being equipped with of ratchet regulates that it turns to turns to the tooth axle, steel ball, little spring, the latch segment that tightens screw and have locking effect.One of structure of spring and pogo barrel is the pointer that the indication spring pressure is housed on spring, is carved with the scale of indication spring pressure on the pogo barrel.The member of rack shaft device, gear ratchet device can be made by aluminium alloy except that spring and little spring.
This portable type lumbar tractor, patient can self carry out draw operations, and easy to operate, lifting is fast, and whole traction apparatus is in light weight, and is easy to process, cost is low, and it is fit to the multiple diseases that need traction therapeutic such as treatment prolapse of lumbar intervertebral disc, chronic lumbar muscle strain, the prominent syndrome of third lumbar vertebra.
Below in conjunction with this utility model being further described by the represented embodiment of Fig. 1-5.
