Abstract
This model utility relates to a traction apparatus for medical purposes for treating cervical spondylosis. For this model utility, a hand wheel is connected with a small friction wheel, the small friction wheel is connected with a large friction wheel, the large friction wheel is connected with a tub wheel, the tub wheel is connected with one end of the ergometer, the other end of the ergometer is connected with a crown block, the block frame is fixed and connected to the front end of the glide bracket, the hand wheel is installed on the small friction wheel, the large friction wheel is axial with the tub wheel and the small friction wheel and the large friction wheel is connected with the front box body. This model utility resolves the issue that the current traction apparatus are complex in operations, apparatuses are scattered, the leather ball leaks air, shoulders pain due to the traction pressure on the two shoulders as well as the complex structure of the double reduction gear box, etc.. This model utility is used to tract and treat the cervical spondylosis and also applied to bone and skin traction. With level I reduction gear box of the friction wheels, this model utility has higher stability and reduce pains suffered by the patients while is characterized in simple driving, small volume, compact structure, flexible movements and simple and convenient operations, etc.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of traction apparatus for the treatment of the cervical spondylosis disease.
Background technology
Cervical traction is pandemic at home and abroad a kind of traditional method for the treatment of cervical spondylosis, to some case, if use properly, can obtain certain curative effect.Cervical traction can be alleviated the musculi colli of spasm gradually by the interaction of pull strength and reverse drag power (being patient's self gravity), eases the pain.Cervical spondylopathy patient all has intervertebral disc degeneration in various degree, causes stenosis of disc space and intervertebral foramina to diminish.By suitable pull strength, the affected part intervertebral space is retracted gradually.It is intrinsic pressure so just to have reduced intervertebral disc, even make it to form negative pressure, both can reply expansible towards periphery fibrous ring, can receive small outstanding intervertebral disc again.The cervical vertebrae physiological curve that occurs for early stage cervical spondylosis becomes straight, and the cervical vertebra alignment is not just waiting situation, can be corrected gradually by traction.When narrow intervertebral space was retracted, intervertebral foramina that both sides are narrow and little joint space were also retracted, and alleviated or removed the compressing or the stimulation of tissues such as nerve root.And can brake effectively, reduce the friction or the stimulation that are caused because of the cervical vertebra abnormal movement, be convenient to muscle, synovial membrane, nerve root, spinal cord etc. and organize disappearing and absorption of inflammatory edema.Along with the elongation in the vertical footpath of cervical vertebra canalis spinalis, vertebral artery spasm, zigzag phenomenon can be improved gradually; It is unobstructed that the blood circulation of cerebrospinal fluid and spinal cord also can become.Like this, the ischemia of brain and spinal cord, anoxia phenomenon will obtain correcting.
Before the present utility model, the easy traction apparatus of a kind of head of a bed can not random and successive adjusting trailing weight, and complicated operation is subject to the unexpected injury of sliding weight of steelyard, and traction appliance disperses, and difficult management is usually lost as sliding weight of steelyard, is not easy to popularize; A kind of multi-sac individually adjusted cervical vertebrae tractor, the ball of calming the anger can leak gas, and brings inflation inconvenience to user; The fixed cervical vertebra tractor of a kind of both shoulders, traction pressure is added on the both shoulders, can cause shoulder pain for a long time; A kind of hand-rail type Hoisting tractor adopts double-reduction gear, complex structure; A kind of multifunction traction device, structure is loaded down with trivial details, uses inconvenient.
Summary of the invention
The purpose of this utility model just is to overcome the various defectives that above-mentioned existing traction apparatus exists, and has designed a kind of novel medical tracting device.
The technical solution of the utility model:
Medical tracting device, its major technique is characterised in that handwheel connects the friction wheel, the friction wheel connects big friction wheel, big friction wheel connects drum, and drum connects ergometer one end by rope, and the ergometer other end connects fixed pulley, pulley yoke is fixedly connected on the sliding support upper end, handwheel is contained on the friction wheel shaft, and big friction wheel, drum are coaxial, before friction wheel, big friction wheel axle all are connected on the casing.
Advantage of the present utility model and effect are that its traction apparatus not only can be used for traction, treatment cervical spondylosis, can also be used for bone traction and skin traction; With one-level friction pulley reducing gear, have advantages of higher stability, can not bring additional misery to the patient; Transmission is simple, easy for installation, volume is little, compact conformation, in light weight, motion advantage such as flexible, simple to operation.
Other advantages of the present utility model and effect will continue to describe below.

The specific embodiment
As Fig. 1,2,3, shown in 4, hook 13 is housed on the sliding support 9, lower draw-bar 14 and casing fixed mount 15, handwheel 8 is contained on 1 on the friction wheel, big friction wheel 2 and drum 6 are coaxial, axle sleeve 7 is enclosed within 1 on friction wheel and upward friction wheel 1 is carried out axial location, 2 of axle sleeve 7 and big friction wheels all are welded on the preceding casing 3, before casing 3 and rear box 4 be connected by screw, rope 16 links to each other with drum 6 and ergometer 17 respectively, ergometer 17 other ends are socketed on the fixed pulley 11, pivot pin 12 is fixed on fixed pulley 11 on the pulley yoke 10, and pulley yoke 10 is fixedly connected on the sliding support 9, and locking brake block 5 is contained in the chute interior (omitting chute among the figure) on the casing 3.
Shown in Fig. 1,2,3,4, traction apparatus is provided with hook 13, lower draw-bar 14, traction apparatus can be installed in the head of a bed by hook; Lie or lean to after on the traction apparatus when human body, reach required angle by the height of regulating sliding support 9; The clockwise direction rotation hand wheel 8 then, drive friction wheel 1, friction wheel 1 drives big friction wheel 2, utilize the frictional force of the driven wheel contact position of friction wheel 1, big friction wheel 2 to make big friction wheel 2 rotations transfer the motion to drum 6 again, drum 6 drives rope 16 pulling ergometers 17, ergometer 17 other ends are socketed on the fixed pulley 11, can observe the numerical value on the ergometer 17 this moment, up to reaching required pull strength, to lock brake block 5 then along sliding between the big or small friction pulley under preceding casing 3 chutes, and play the locking braking and prevent counter-rotating; Draw then; After traction therapeutic finishes, open locking brake block 5, and reversing handle 8, make ergometer 17 loose.
This utility model not only can be used for traction, treatment cervical spondylosis, and can carry out bone traction and skin traction, and compact conformation has satisfied the demand of patient's different aspect.
The scope that this utility model is asked for protection is not limited to the description of this specific embodiment.
