Description

Technical Field

[0001] The utility model belongs to the technical field of bone orthopedic appliances, in particular to a spinal correction traction bed. Background Art

[0002] Scoliosis includes a condition where the spine bends to one side in a C-shape or to both sides in an S-shape. Scoliosis is often accompanied by rotation of the spine. Scoliosis not only affects the appearance of the spine, causing uneven shoulders and back and poor posture, but also affects cardiopulmonary function and affects children's development and physical health. Among the treatment methods for scoliosis, surgery has a high risk and is expensive; currently, instruments are commonly used for correction.

[0003] The disclosed patents provide a variety of correction structures, most of which use the three-point force principle to apply force to the spine and produce a corrective effect based on the action force, reaction force and force decomposition.

[0004] However, the spinal rotation caused by scoliosis cannot be corrected in a targeted manner, which affects the correction effect. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model provides a spinal correction traction bed, which can simultaneously achieve spinal traction and correction of the rotated spine, and has a better correction effect. The technical solution of the utility model is as follows:

[0006] A spinal correction traction bed comprises a bed frame and a correction traction mechanism, wherein the correction traction mechanism comprises a front bed board, a middle bed board and a rear bed board arranged on the bed frame; the middle bed board comprises at least two mutually independent rotating bed boards, each rotating bed board is fixedly connected to a connecting block via two parallel connecting members at the bottom, the connecting block is fixedly connected to a rotating drive mechanism via a connecting shaft, and the rotating drive mechanism drives the connecting block together with the connecting member and the corresponding rotating bed board to rotate with the connecting shaft as the center axis.

[0007] Preferably, an arc-shaped groove is provided at the bottom of each rotating bed board, and the spinal correction traction bed is provided with a cylindrical support rod, both ends of the support rod are fixed to the front bed board and the rear bed board, and the arc-shaped groove at the bottom of the middle rotating bed board is mounted on the support rod.

[0008] As a preferred embodiment, the connecting member is a compression spring, and its elastic deformation is used to assist in adjusting the tilt angle of the corresponding rotating bed board.

[0009] In order to achieve compression correction by applying lateral pressure and to adapt to patients of different body shapes, two vertical plates are respectively arranged on the two side frames of the bed frame and at the middle bed board, and longitudinal slots are arranged on the vertical plates. Fastening bolts are respectively arranged at the upper and lower ends of the vertical plates, and a longitudinal sliding bar passing through the longitudinal slot is arranged between the two vertical plates on the same side. A screw support seat is arranged on the longitudinal sliding bar, and a transverse screw is connected to one side of the screw support seat and a rocker is arranged on the other side. The rocker is rotated to control the transverse screw to extend or retract toward the inner side of the bed board; the screw support seat is detachably fixed to the longitudinal sliding bar by fastening bolts to achieve movement of the longitudinal position of the transverse screw.

[0010] As a typical embodiment, the longitudinal slide rod is cylindrical, and the screw support seat together with the transverse screw rod can swing around the axis of the longitudinal slide rod at a certain angle and then be fixed with a fastening bolt.

[0011] Preferably, a pressure block is arranged at the end of the transverse screw rod, and the pressure block is a flexible pad made of silicone or rubber.

[0012] Preferably, the spinal correction traction bed also includes a traction control device, a hip joint fixation belt is arranged above the middle bed board, and is connected to the traction control device through a traction rope, the traction control device includes a control cabinet arranged at one end of the rear bed board and a steering wheel arranged on the control cabinet, and a traction motor arranged inside the control cabinet, and the output shaft of the traction motor is connected to the traction rope to control the length of the traction rope.

[0013] Furthermore, the control cabinet is provided with rotation control motors for controlling the three rotating bed boards respectively. Each rotating bed board is connected to its own rotation control motor via a connecting piece, a connecting block and a connecting shaft to achieve independent control of its own rotation angle.

[0014] Furthermore, it also includes a control panel, which is located on the control cabinet and is provided with control components respectively connected to the rotating control motor and the traction motor to control the start, stop and operation of each control motor and the traction motor to control the length of the traction rope and the swing angle of the rotating bed board to perform traction correction.
