Description
Technical Field
The invention relates to a lumbar vertebra tractor, in particular to an intermittent self-adaptive lumbar vertebra tractor.
Background
The lumbar intervertebral disc protrusion is one of the more common diseases, and clinical statistics show that the lumbar intervertebral disc protrusion is one of the most common diseases in orthopedic outpatients and is also the most common cause of lumbocrural pain. The main reason is that after various parts of the lumbar intervertebral disc (nucleus pulposus, annulus fibrosus and cartilage plates), especially the nucleus pulposus, have degenerative changes of different degrees, under the action of external force factors, the annulus fibrosus of the intervertebral disc is ruptured, and nucleus pulposus tissues protrude (or are extruded) from the ruptured part to the back or in the vertebral canal, so that adjacent spinal nerve roots are stimulated or pressed, and a series of clinical symptoms such as lumbar pain, numbness and pain of one lower limb or two lower limbs are generated. The incidence of lumbar intervertebral disc protrusion is highest in 4-5 parts of the waist and 5-1 parts of the waist, and accounts for about 95 percent. The treatment of the lumbar intervertebral disc protrusion is mainly divided into surgical treatment and non-surgical treatment, and traction treatment is an important and main treatment method in the non-surgical treatment. The lumbar traction is to utilize the traction force and the counter traction force to act on the lumbar, and achieve the purpose of treating the lumbar disc herniation by traction in opposite directions. Lumbar traction can increase the lumbar clearance, mainly the lumbar 3, 4, 5 and sacral 1 clearances. According to the research, the lumbar intervertebral space is widened by 1.5-2.5 mm after traction compared with the lumbar intervertebral space before traction, the inner part of the lumbar intervertebral space becomes negative pressure due to the widening of the intervertebral space, and the tension of the longitudinal ligament is favorable for the protruded nucleus pulposus part to reduce or change the relation between the protruded nucleus pulposus part and the nerve root. The intervertebral space is enlarged, and the zygapophyseal joint is pulled open, so that the intervertebral foramen can restore to the normal shape, and the extrusion to nerve roots is relieved. Traction can also make lumbar vertebra fully rest, reduce the stimulation of movement, be beneficial to the absorption and the elimination of tissue congestion and edema, and also can relieve muscle spasm and relieve intervertebral pressure.

(4) the tractor has simple structure and convenient use, and can be used independently at home.
Drawings
Fig. 1 is a schematic structural view of the intermittent self-adaptive lumbar vertebra tractor of the present invention.
In the figure, 1 is a back plate, 2 is a traction rod, 3 is an elastic part, 4 is a sliding rail, and 5 is a sliding fixing block.
Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments.
Examples
As shown in fig. 1, an intermittent self-adaptive lumbar vertebra tractor comprises a back plate 1, two traction rods 2 are symmetrically arranged on two sides of one end of the back plate 1, the traction rods 2 and the back plate 1 form an inclined angle, one ends of the traction rods 2 are rotatably connected with the back plate 1, the middle parts of the traction rods 2 are fixedly supported with the back plate 1 through elastic pieces 3, a first fixing band for fixing the upper part of a body of a user is arranged at one end of the traction rods 2 connected with the back plate 1, a second fixing band for fixing the waist of the user is arranged at the other end of the traction rods 2, and the first fixing band and the second fixing band. The design of the backboard 1 can be customized, attached and manufactured according to human engineering.
The traction force F of the retractor is equal to the weight G of the user multiplied by a traction coefficient K, which is a constant related to the angle of inclination. The traction coefficient K is a specific value and is obtained by comprehensively calculating according to the strain coefficient of the elastic member 3, the weight of the patient, the degree of reduction of the lumbar intervertebral space indicated in the imaging data and the individual condition (such as age, sex, treatment process and the like) of the patient, that is, the traction coefficient K of each patient is specifically set according to the condition of the patient and is variable according to the treatment condition.
One end of the traction rod 2 is rotatably connected with the backboard 1 through a rotating shaft, and the rotating connection part of the traction rod 2 and the backboard 1 does not generate mutual rotating force. Two ends of the elastic part 3 are respectively fixed on the backboard 1 and the traction rod 2 through a sliding structure, so that the inclination angle formed by the traction rod 2 and the backboard 1 is adjustable, the sliding structure comprises a sliding rail 4 respectively arranged on the backboard 1 and the traction rod 2 and sliding fixing blocks 5 arranged at two ends of the elastic part 3, a row of fixing grooves are distributed on the sliding rail 4, and the sliding fixing blocks 5 slide to a set position and are clamped into the fixing grooves for fixing. When the traction coefficient needs to be adjusted, the inclination angle between the traction rod 2 and the back plate 1 can be adjusted by adjusting the fixed positions of the sliding grooves on the back plate 1 and the traction rod 2 at the two ends of the elastic part 3, so that the traction coefficient is changed, the individuation of the traction coefficient is realized, and the traction coefficient suitable for each patient is different. The elastic member 3 includes a support rod, a spring, and a hinge having a set strain coefficient.
The intermittent self-adaptive lumbar vertebra tractor has the working principle that: the user adopts the position of crouching the knee supine position to lie on backplate 1 flatly, and the tractor open angle direction is towards patient's foot, and fixed user's health upper portion (like chest or armpit portion) of first fixed band, the fixed user's waist of second fixed band, above-mentioned first fixed band and second fixed band accessible shrink area are binded or other modes. The user uses the feet and the shoulders as supporting points, the waist exerts force to do up-and-down tidal movement, when the user moves downwards, the gravity of the user acts on the traction rod 2, the traction rod 2 presses downwards, the traction rod 2 generates traction force, the traction force is generated by the gravity of the user, and continuous traction is realized; when the user moves upwards, the traction force disappears, so the traction is intermittent. In the process, the upward movement needs the force of the waist of the patient, so that the effect of exercising the muscles of the back can be achieved, and the muscles of the back are strong, thereby being beneficial to the recovery of the lumbar disc herniation.
