Detailed Description

Referring to fig. 1-2, in an embodiment of the present invention, a lumbar traction device includes a support plate 1, an upper bed body 2 and a lower bed body, the lower bed body is divided into a first bed body 3 and a second bed body 4, one end of the first bed body 3 close to the upper bed body 2 is fixedly connected with a clamping plate, a rotating rod 5 is arranged at the upper part of the supporting plate 1, the clamping plate is hinged with the rotating rod 5, a rotating shaft 6 is arranged at one side of the first bed body 3 close to the supporting plate 1, the rotating shaft 6 is hinged with the first bed body 3, a spring 7 is connected between one end of the rotating shaft 6 far away from the first bed body 3 and the first bed body 3, the tail end of the rotating shaft 6 far away from the first bed body 3 is fixedly connected with a tooth piece 8, the periphery of the tooth piece 8 is rotatably connected with a blocking piece 9, one side of the supporting plate 1 close to the first bed body 3 is fixedly connected with a corner motor 10, and the output end of the corner motor 10 is fixedly connected with a gear 11 matched with the tooth piece 8.

When the lumbar traction device works, when a patient lies on the lumbar traction device, the upper body of the patient is fixed on the upper bed body 2, the leg parts of the patient are respectively fixed on the first bed body 3 and the second bed body 4, and when the body of the patient is firmly fixed, the lumbar of the patient is pulled and stretched; because the physical quality and the suffered illness process of the patient are different, the damage degree of the lumbar vertebra of the patient is different, the whole formula should be planned when the patient is treated, and the left and right lumbar vertebrae of the patient can be respectively treated by using different traction forces and different traction angles through the first bed body 3 and the second bed body 4; first bed body 3 rotates slowly under the drive of corner motor 10, and spring 7 tractive tooth piece 8, when first bed body 3 rotates from top to bottom, makes tooth piece 8 and gear 11 mesh together all the time, and the separation blade 9 of being connected with tooth piece 8 rotation can prevent that tooth piece 8 and gear 11 are unexpected to drop to along with the tilting of first bed body 3 and second bed body 4, separation blade 9 also can be along with rotating, keeps with the contact of gear 11, nevertheless does not disturb the rotation of gear 11.

Referring to fig. 1, the rotating rod 5 is rotatably hinged to the supporting plate 1, a hydraulic prop 12 is disposed on one side of the rotating rod 5 away from the upper bed body 2, one end of the hydraulic prop 12 close to the rotating rod 5 is hinged to the rotating rod 5, and the other end of the hydraulic prop 12 is hinged to the supporting plate 1.

During specific work, the angle of the up-and-down inclination of the first bed body 3 and the second bed body 4 is adjusted by adjusting the hydraulic prop 12, so that the left lumbar vertebra and the right lumbar vertebra of a patient can be pulled and stretched in an all-around manner, and the lumbar vertebra of the patient can be recovered.

Referring to fig. 1 and 4, a clamping motor 13 is fixedly connected to one side of the upper bed body 2 close to the support plate 1, a clamping gear 14 is fixedly connected to an output end of the clamping motor 13, a rack 15 matched with the clamping gear 14 is slidably connected to one side of the upper bed body 2 close to the clamping motor 13, and a clamping column 16 is fixedly connected to one end of the rack 15 far from the clamping motor 13.

When the patient lies on the device, the upper body of the patient is fixed through the clamping part so as to safely and stably stretch and draw the lumbar, the clamping columns 16 are clamped in the axilla of the forehead of the patient, the pulling-back movement of the rack 15 is controlled by controlling the clamping motor 13, so that the distance between the two clamping columns 16 is controlled, and the patient is tightly clamped on the upper bed body 2 so as to be convenient for subsequent treatment.

Referring to fig. 3 and 5, a stretching motor 17 is fixedly connected to one end of the first bed body 3 away from the upper bed body 2, a stretching gear 18 is fixedly connected to an output end of the stretching motor 17, a stretching rack 19 matched with the stretching gear 18 is slidably connected to one side of the first bed body 3 close to the stretching motor 17, a locking mechanism is fixedly connected to one end of the stretching rack 19 away from the stretching motor 17, the locking mechanism includes a base 20 and a collar 21, the collar 21 is hinged to the base 20, a bayonet 22 is arranged at one end of the base 20 away from the hinged portion, the bayonet 22 is slidably connected to the base 20, and a detent spring 23 is arranged between the bayonet 22 and the base 20.

When the patient upper body fixing device works specifically, after the upper body of the patient is fixed, the leg of the patient needs to be fixed, the ankle of the patient is placed into the base 20 at the moment, the clamping ring 21 is pressed down, the clamping ring 21 is clamped under the action of the clamping pin 22, and the ankle is stably fixed on the base 20; the patient starts treatment through the stretching part, and at the moment, the stretching motor 17 is started to stretch the leg part of the patient, so that the lumbar vertebra of the patient is stretched; when the treatment is finished, the clamping pin 22 is pulled, the limiting effect of the clamping pin 22 is canceled, the clamping ring 21 is opened, and the ankle of the patient can leave the base 20.

Referring to fig. 1, a support column is fixedly connected between the upper bed body 2 and the support plate 1.

When the bed works, the bed is used for supporting the upper bed body 2 to be far away from the ground, and a certain height is kept, so that a patient can have a comfortable lying height.

Referring to fig. 1, an upper body strap is fixedly connected to the upper bed body 2, and leg straps are fixedly connected to the first bed body 3 and the second bed body 4.

In particular, the strap is used to more stably secure the patient to the device during operation, avoiding the accidental flipping of the device during stretching.

The working principle of the invention is as follows: when a patient lies on the device, the clamping posts 16 are clamped in the armpits of the patient, and the clamping motor 13 is controlled to adjust the distance between the clamping posts 16 to ensure that the clamping posts 16 are tightly attached to the two sides of the patient so as to stably and firmly fix the upper body of the patient; the ankle of the patient is placed on the base 20 and is fixed through the clamping ring 21, all the bridles are fixed at the moment, and the whole fixing process is finished, so that the patient is firmly fixed on the device; the stretching motor 17 is started at the moment, the lumbar vertebrae of the patient are stretched, when the lumbar vertebrae on two sides of the patient need to be stretched respectively, different positions are adjusted by adjusting the corner motor 10 and the hydraulic prop 12, so that the lumbar vertebrae of the patient are in a more comfortable stretching state, and secondary damage caused by forced stretching is avoided.
