Description

Self-service spinal surgery extension table

A kind ofly treat the medical apparatus and instruments that rachialgia disease is used.

Along with the continuous progress of diagnostic means, the past is the human spine pain disease of rheumatism by mistaken diagnosis often, and the overwhelming majority is diagnosed as the spinal column intervertebral disc prolapse now, and a large amount of patients only need traction therapeutic a period of time just can remove pain and fully recover.At present, traction device commonly used is to hang weight at the head of a bed, and promptly an end of human body top fixed tractive ties up on the human body bottom, and the other end is walked around the pulley that is positioned at the head of a bed and hung up weight.Its weak point is that the frictional resistance between human body and the bed surface is big, and propulsive efficiency is low, and the medical expense height must be leant on hammer by other people and just can finish traction work, and patient oneself can not operate.The hydraulic haulage bed of Chu Xianing in recent years, though there is minority can have following defective from line operate through the patient of special instruction refining: the one, complex structure, operated key is more, and the people who refined by special instruction can not operate; The 2nd, use 3 hours needs to shut down continuously and have a rest, otherwise hydraulic fluid temperature is too high, influence machine and run well; The 3rd, security reliability is poor, and reason is that hitch structure system is rigidly connected, and does not have the ashamed change stage that trace slowly increases in the distraction procedure, and traction increases and realizes by incipient moment entirely, therefore as easy as rolling off a logly pulls or draw residual patient.In recent years a kind of turbine worm transmission traction bed also occurs, it can not realize the patient from line operate, exists hitch structure system to be rigidly connected again equally, pulls or draw residual patient's defective easily.

The purpose of this utility model provides a kind of self-service orthopedic traction bed, accomplishes the patient from line operate, and is safe and reliable, the propulsive efficiency height, and use cost is low.

The purpose of this utility model is to realize like this; The bed that the below is equipped with four movable wheels is fixed with rail bracket cashier's office in a shop, the rail bracket right side installs and fixes mattress, trailer wagon is placed in the rail bracket left side by wheel or spin, pull rope one end ties up to rail bracket left end place, it walk around in order the left movable pulley that is positioned at trailer wagon middle part and left side fixed pulley, be positioned at the rail bracket middle part on the upper side fixed pulley and be positioned at 2 fixed pulleys of a cabinet, tie up at last on the counterweight frame.The gravity of counterweight will drive trailer wagon left side movable pulley, and trailer wagon is moved to the left.Elevator steel wire one end ties up to the trailer wagon right side, it is walked around the right movable pulley that is positioned at trailer wagon middle part in order, is positioned at rail bracket middle part fixed pulley on the lower side, be wound on the rope sheave, the main shaft that is set with rope sheave and ratchet is installed on the cabinet base plate by supporting base, and the main shaft outer end is equipped with crank rocker.Ratchet and linkage lever thereof also are installed on the supporting base, and an end of linkage lever is equipped with extension spring.The effect of extension spring is that ratchet tightly is stuck on the ratchet, and ratchet can only just be changeed, and can not reverse.There is the control steel wire in the other end system of lever, and the control steel wire other end ties up on the ratchet handle, and the ratchet handle is installed on the side top support plate by support plate hanging column.Hook is hinged on the ratchet handle by rotating shaft, and when ratchet was shaken hands down deflection, hook hung on the hanging column after will walking around hanging column earlier under action of gravity, thereby pulling control steel wire makes ratchet break away from ratchet.

For rapid operation, this utility model also disposes the off-load pull bar, and there are trepanning and folding hook in its lower end.Off-load drag link sleeve borehole jack is torn hook open outwardly under the normal condition on the handle that unloads the handle crank, and the rotation of crank rocker only causes the swing of off-load pull bar and do not rotate.Receive rope and during rotary main shaft, the off-load pull bar just overturns 180 ° and installs when needs, trepanning still is enclosed within on the crank rocker handle, and it tears hook open then inwardly not on crank rocker, the arm of force that the off-load pull bar is become prolong, rotating spindle like a cork.

Using method of the present utility model is as follows:

1, as required, on the counterweight frame, hang up the counterweight of corresponding weight.

2, shake main shaft with crank rocker and be rotated in the forward, rope sheave coiling steel wire spurs right movable pulley and moves right, and makes trailer wagon till fixedly mattress is drawn close.Meanwhile, left movable pulley also moves right, and promotes counterweight by pull rope.

For rotating spindle easily, can be with 180 ° of installations of off-load pull bar upset, when the arm of force uses.But note after the main shaft rotation is finished, the off-load pull bar to be set back and promptly rolling over hook outwardly.

3, the patient lies on the bed, own with the fixing band on the trailer wagon lower body part binding earlier, and the reuse fixedly fixing band on the mattress bundlees upper body part.

4, the patient up lifts the off-load pull bar in the rear with left hand, makes the crank rocker positive deflection slightly, by main shaft drive ratchet also positive deflection make ratchet not push down ratchet slightly.Meanwhile, patient's right hand down deflectable pawl is shaken hands and is made the hanging column that tangles on the support plate, thereby pulling control steel wire deflects linkage lever, forces ratchet to leave ratchet on the one hand, makes the extension spring elongation on the other hand.

After ratchet left ratchet, counterweight fell under action of gravity, drew left movable pulley by pull rope and was moved to the left, thereby trailer wagon is moved to left, and reached the purpose of traction.Meanwhile, right movable pulley also is moved to the left, by the counter-rotating of elevator steel wire pulling rope sheave.

Compared with the prior art, this utility model has following characteristics:

1, simple to operate, do not need other people to assist, the patient can finish the traction overall process voluntarily, reduces smelting and treats expense.

2, owing to adopt movable pulley mechanism, pull strength increases than traditional extension weight method and is twice, and the dolly rolling friction replaces the static friction between human body and the bed surface, has therefore improved propulsive efficiency, has accomplished that the traction curative effect is rapid, and healing time is short.

3, safe and reliable, can not pull or draw residual people.Because in the distraction procedure, Weight gravity is to continue to be added on the human body evenly, and As time goes on makes human body slowly draw growth, so very safe.

4, not electricity consumption, pollution-free, no dry sound.

5, applied widely, be widely used in hospital, clinic and patient family.
