Description

Cervical vertebra tractor

This utility model relates to a kind of medical apparatus and instruments, especially a kind of cervical vertebra tractor.

Common in clinical have the needs of patients of multiple cervical spondylosis to do cervical vertebrae traction.More present hospital adopts patient to lie on a bed and fixes as human body, and head traction or enemy and trunk are simultaneously to the both direction tractive, and this needs others' help, controls oneself and can't regulate the pulling force size.

The purpose of this utility model provides a kind of cervical vertebra tractor that can make patient oneself carry out cervical traction.

For achieving the above object, the technical solution of the utility model is: in the seat bottom of seat, rotatably support is equipped with cylinder, and an end of cylinder is fixed with ratchet, stretches out in the ratchet outside on the cylinder spindle nose of chair frame and fixes a handwheel; One end can insert the control stick between the ratchet ratchet, and its middle part can be bearing in up and down on the chair frame rotationally, and the other end stretches to seat the place ahead.Between its supporting-point and insertion ratchet ratchet one end, there is extension spring to be connected with the chair frame; One end of pull rope is fixed and on cylinder, and the fixed pulley of the other end through being fixed on the support on the chair frame upwards hangs down to the top of seat through the cantilevered distal end of support, and its low end is fixed with and can be enclosed within the traction casing that the head part does tractive.

During use, the people is sitting on the seat, traction casing is enclosed within on the head, with foot-operated lower control arm, itself and ratchet are broken away from, the reuse hands rotates handwheel, drives ratchet and cylinder and rotates, and the traction casing of pull rope pulling simultaneously is stretched people's cervical region, treat that the people feels pulling force when moderate, lift foot and unclamp control stick, under the effect of extension spring, rod end inserts the locking of ratchet tooth chien shih cylinder again.

This kind cervical vertebra tractor is manually made the degree of tightness tractive cervical region of self regulation pull rope because the patient can oneself be sitting on the seat by foot, need not the stranger and helps, and control oneself to regulate than others with sensation and help down adjusting to comfort.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the front view of this utility model cervical vertebra tractor;

Fig. 2 is for using the structure chart of doing braking control with the co-axial ratchet of cylinder among Fig. 1.

Among Fig. 1, in the bottom of the seat 6 of seat, two ends are equipped with cylinder 3 with the bearing block lateral support, and the one end is fixed with ratchet 5, in ratchet 5 outsides, stretch out on the spindle nose of cylinder 3 of chair frame 7 and are fixed with handwheel 4; One end can insert the control stick 2 of the between cog of ratchet 5, and its middle part can be bearing in up and down on the chair frame 7 rotationally, and the other end stretches to seat the place ahead, has extension spring 1 to link to each other with chair frame 7 between its fulcrum and ratchet one end that inserts ratchet 5; One end of pull rope 13 is fixed and on cylinder 3, and the fixed pulley 12 on the support 14 of the other end through being fixed on chair frame 7 and making progress lets droop to the top of seat face 6 through cantilever 11 ends, and its end points is fixed with hook 10, and traction casing 9 hangs over cover and draws on the hook 10.

For when doing tractive in conjunction with various physical therapys, also can on support 14, be fixed with the seat that multiple physiotherapy apparatus 8 is installed.
