The motor and the speed reducer are respectively arranged in a dynamic box on the base, the upper end of the vertical column is provided with a transmission box, one end of a main shaft in the vertical column is connected with the speed reducer, and the other end of the main shaft is connected with a rubber belt wheel in the transmission box; another rubber belt wheel in the transmission box drives the traction mechanism with the cervical vertebrae swing. The utility model has the advantages of skill structural design, small size, light weight, low noise, large regulation range, and remarkable therapy effect.

Description

Dynamic cervical traction machine

This utility model relates to a kind of medical traction machine, particularly a kind of dynamic cervical traction machine.

Spondylotic radiculopathy and vertebral artery ischemia myelopathy utilize cervical traction to treat usually, and the machinery that draws at present mostly is pulley and balancing weight, can only realize static state traction, curative effect is not ideal enough, designer of the present utility model had designed a kind of dynamic cervical traction machine before this, this traction machine is by motor, reductor, base, column, seat and cervical vertebra swing haulage gear are formed, motor, reductor all is contained in the transmission case of column upper end, because of the entire machine center of gravity too high, therefore the chassis do massiveness, because of power and drive mechanism all in overhead the transmission case, therefore noise is bigger, is unfavorable for patient's treatment with all worries set aside, and the amplitude of accommodation of swinging haulage gear because of cervical vertebra is less, can not regulate the size of pull strength freely, also be difficult to adapt to the variation of patient's stature.

The purpose of this utility model will overcome above-mentioned shortcoming exactly provides a kind of good looking appearance rational in infrastructure, noise low, and can adapt to different stature people's variation, regulates dynamic cervical traction machine freely.

For achieving the above object, this utility model adopts technical scheme as described below: dynamically the cervical traction machine comprises base, column, seat, motor, reductor and cervical vertebra swing haulage gear, one headstock is arranged on the base of column lower end, there is a transmission case column upper end, motor, in all base-mounted headstock of reductor, correspondence is equipped with two belt pulleys on the base plate of transmission case, one main shaft is arranged in the column, one end of main shaft is connected with the output shaft of reductor, the other end is connected with the turning cylinder of a belt pulley, two belt pulleys connect by belt, the turning cylinder of another belt pulley is the screw shaft of cervical vertebra swing haulage gear, also connect between motor and the reductor by belt, cervical vertebra swing haulage gear comprises screw shaft, slide block, adjusting rod, lifting handwheel and head-shield, slide block set is on screw shaft, the lifting handwheel is contained on the screw shaft of slide block bottom, adjusting rod is made up of trocar sheath and interior loop bar, trocar sheath is horizontal positioned, one end is fixedly connected on the slide block, be with interior loop bar in the other end, one weight beam is arranged between the other end of interior loop bar and the head-shield, one vertical lift device is arranged below the seat, the circuit control box of timing controlled motor rotating is arranged on the sidewall of headstock.

Adopt the dynamic cervical traction machine structural design of said structure ingenious, volume is little, in light weight, noise is little, the amplitude of accommodation is big, can adapt to different stature people's variation.

Below in conjunction with accompanying drawing this utility model is described in detail.

Fig. 1 is a structural representation of the present utility model.

With reference to Fig. 1.Dynamically the cervical traction machine comprises base 22, column 16, seat 25, motor 19, reductor 23 and cervical vertebra swing haulage gear, one headstock 18 is arranged on the base of column 16 lower ends, there is a transmission case 1 the column upper end, motor 19, reductor 23 all is contained in the headstock 18, correspondence is equipped with two belt pulleys 2 on the base plate 15 of transmission case, 4, main shaft 17 is arranged in the column 16, main shaft 17 1 ends are connected by pin with the output shaft of reductor 23, the other end is connected by pin 14 with the turning cylinder 13 of belt pulley 2, belt pulley 2,4 are connected by belt 3, also connect between motor and the reductor by belt, can reduce noise greatly like this, the turning cylinder of belt pulley 4 is the screw shaft 5 of cervical vertebra swing haulage gear.

Cervical vertebra swing haulage gear comprises screw shaft 5, slide block 11, adjusting rod 6, lifting handwheel 10 and head-shield 8, slide block 11 is enclosed within on the screw shaft 5, chute 12 is arranged on the screw shaft 5, there is dowel to match in the slide block 11 with chute 12, lifting handwheel 10 is contained in slide block 11 bottoms, lifting handwheel bottom has a sheath 9 lower end of screw shaft 5 is covered, adjusting rod 6 is made up of trocar sheath and interior loop bar, trocar sheath is horizontal positioned, the one end is fixedly connected on the slide block 11, be with interior loop bar in the other end, between the other end of interior loop bar and the head-shield 8 weight beam is arranged, hydraulic verticallifting device 26 is arranged below the seat 25, the lifting of seat is by joystick 24 controls, the circuit control box 20 that the rotating of a timing controlled motor is arranged on the medial wall of headstock 18, its control panel 21 is contained on the outer wall of headstock.

Regulate the height of seat when giving treatment to a patient according to the height of patient's stature, re-adjustment adjusting rod 6 pull out length, can change the radius of turn and the traction angle of dynamic traction, allow patient be sitting on the seat, catch head with head-shield, regulate the height of lifting handwheel, can regulate pull strength, and the size of pull strength can show on weight beam 7, after these all are ready to, opens gauge tap, motor is made forward and reverse timing alternate rotation, pass through reductor again, main shaft, belt pulley 2,4 can make head-shield drive patient's head does forward and oppositely alternately rotation around screw shaft, thereby reaches the dynamic traction cervical vertebra, the purpose of treatment disease.
