Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a seat adjustable traction frame. Background Art

[0002] Cervical traction is the main means of relieving symptoms in the treatment of cervical spondylosis. Effective traction can relieve compression of nerves, blood vessels, and spinal cord, and quickly relieve symptoms of cervical spondylosis, loosen adhesions of joint capsules, improve and restore uncovertebral joints, adjust small joint dislocations and vertebral slippage, adjust and restore the damaged internal and external balance of the cervical spine, and restore the normal function of the cervical spine. When in use, the traction handwheel is used to drive the tightening and relaxation of the suspension rope to achieve the traction effect on the patient's cervical spine.

[0003] Medical workers have found that during traction therapy, the fixed-structure traction seat cannot fully match the patient's body shape and size, which can easily lead to the patient's inability to maintain a comfortable posture during long-term traction therapy, making the patient prone to muscle stiffness and fatigue, reducing the comfort of traction therapy. For this reason, we propose a traction frame with an adjustable seat. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the existing traction therapy, due to the differences in the body shapes and sizes of patients, the traction seat with a fixed structure cannot be fully matched, which easily leads to the patient being unable to maintain a comfortable posture during long-term traction therapy, making the patient prone to muscle stiffness and fatigue, and reducing the comfort during traction therapy. The utility model provides a traction frame with an adjustable seat.

[0008] Furthermore, a rotation adjustment handle mechanism is provided on the top of both sides of the support frame, and the rotation adjustment handle mechanism includes a chair handle, and a rotating shaft is fixedly installed at one end of the bottom of the chair handle, and the rotating shaft is inserted into the interior of the support frame.

[0009] Furthermore, a rotating frame is fixedly installed at a center position of the bottom of the chair handle, a grip rod is connected through the rotating frame, a spring is fixedly connected to one end of the grip rod away from the rotating frame, the upper end of the spring abuts against the bottom surface of the chair handle, and a friction block is fixedly installed at the other end of the grip rod, and the friction block abuts against the upper side wall of the support frame.

[0010] Furthermore, a friction sleeve is provided at a position of the support frame corresponding to the contact position of the friction block.

[0011] Furthermore, the latching tooth is meshed with the gear, and the gear can drive the latching tooth to slide along the inside of the latching slot.

[0012] Furthermore, a layer of convex points is arranged on the outer surface of the fixing ring, and a rubber friction pad is fixedly connected to a side of the fixing ring corresponding to the lower end of the limiting block.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the utility model is in use, the patient first sits on the chair seat, and then uses the traction hand wheel to adjust the suspension rope to adjust the height of the suspension frame. After the patient's position is stable, if the patient wants to move the body, the rotating wheel can be turned to drive the rotating rod, and the gear on the rotating rod can drive the latching teeth to move forward and backward, and the latching teeth can drive the chair seat to move forward and backward.

[0015] 2. When the utility model is in use, if the patient wants to place his arm more comfortably during traction, he can hold the grip at the bottom of the chair handle. When the grip is squeezed, it will rotate along the rotating frame.
