Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an orthopedic traction frame. Background Technology

[0002] Orthopedics is an important medical specialty that primarily diagnoses and treats diseases related to the musculoskeletal system, including bones, joints, muscles, tendons, and ligaments. Its scope encompasses various traumatic fractures, bone tumors, osteoporosis, arthritis, joint dislocations, cervical spondylosis, lumbar disc herniation, and soft tissue injuries. Treatment methods range from conservative approaches, such as using medication to relieve pain and reduce inflammation, physical therapy to improve local blood circulation and relax muscles, and rehabilitation exercises to aid in functional recovery, to surgical treatments, including open reduction and internal fixation of fractures, joint replacement, and spinal surgery, depending on the specific condition. The department is often subdivided into trauma orthopedics, joint surgery, and spinal surgery subspecialties, with professional doctors, nurses, and rehabilitation therapists working together to safeguard the health of patients' musculoskeletal systems. To prevent displacement after a fracture, an orthopedic traction frame is often used.

[0003] Currently available orthopedic traction frames mainly consist of a main frame, traction device, and fixation device. During use, the appropriate traction frame is selected based on the patient's traction location, and the initial traction weight is determined based on the patient's condition, weight, and physical tolerance. Traction is then applied to the area requiring traction. However, when subjected to significant traction force or unintentional external forces from the patient, the traction frame is prone to swaying or displacement. This not only affects the traction effect but also poses certain safety hazards. To address these issues, existing technology only optimizes the base of the traction frame, increasing the contact area between the base and the ground or bed, using a wider base structure with anti-slip rubber pads to enhance friction and improve overall stability, preventing easy slippage or swaying. However, it does not improve the traction force adjustment function, resulting in insufficient precision in traction force adjustment or inconvenient adjustment operation, affecting the treatment effect and failing to meet usage requirements. Utility Model Content

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an orthopedic traction frame, comprising a support plate, a motor fixedly connected to the center of the bottom surface of the support plate, a drive shaft fixedly connected to the output end of the motor, a drive wheel fixedly connected to the front side of the outer wall of the drive shaft, a tension steel wire rotatably connected to the outer wall of the drive wheel, a connecting block fixedly connected to the other end of the tension steel wire, a placement plate fixedly connected to the left side of the connecting block, a placement plate fixedly connected to the bottom left side of the placement plate, a fixing strap fixedly connected to the top left side of the placement plate, a slide rail slidably connected to the bottom of the placement plate, the bottom of the slide rail fixedly connected to the center of the top surface of the support plate, a support block one fixedly connected to the center of the center of the top right side of the support plate, a rotating wheel one rotatably connected to the center of the support block one, a support block two fixedly connected to the center of the center of the bottom right side of the support plate, a rotating wheel two rotatably connected to the center of the support block two, and a lifting mechanism provided on the left side of the bottom surface of the support plate, the lifting mechanism being used to adjust the height of the traction frame.

[0006] As a further description of the above technical solution: the lifting mechanism includes a telescopic rod, the top surface of which is fixedly connected to the bottom surface of the support plate around the perimeter. A main telescopic rod is slidably connected to the outer wall of the telescopic rod. A base plate is fixedly connected to the bottom of the main telescopic rod. Multiple sliding blocks are slidably connected to the right side of the top surface of the base plate. A push bar is rotatably connected to the top of each sliding block. A second sliding block is rotatably connected to the bottom of the push bar. A threaded rod is threadedly connected to the middle of each sliding block. A rotating bar is fixedly connected to the rear side of the threaded rod. A handle is fixedly connected to the bottom rear side of the rotating bar.

[0007] As a further description of the above technical solution: a rotating sleeve is rotatably connected to the middle of the outer wall of the handle, and a sliding groove is provided on the right side of the top surface of the base plate.

[0008] As a further description of the above technical solution: a limiting block is fixedly connected to the left side of the slide rail, the bottom of the limiting block is fixedly connected to the middle left side of the top surface of the support plate, and an L-shaped fixing block is fixedly connected to the right side of the motor.

[0009] As a further description of the above technical solution: a push handle is fixedly connected to the middle right side of the support plate, and an anti-slip sleeve is fixedly connected to the middle outer wall of the push handle.

[0010] As a further description of the above technical solution: a storage battery is fixedly connected to the middle right side of the top surface of the base plate, and a controller is fixedly connected to the middle left side of the top surface of the base plate.

[0011] As a further description of the above technical solution: wheels are fixedly connected to the bottom perimeter of the base plate, and sound-absorbing pads are fixedly connected to the outer walls of the wheels.

[0012] As a further description of the above technical solution: the middle of the second support block is rotatably connected to a rotating shaft, and a nameplate is fixedly connected to the front left side of the top surface of the support plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when traction treatment is required for a patient, the part of the patient that needs traction is fixed to the placement plate by a fixing strap and supported by the placement plate. The motor is started to output power to drive the transmission shaft to rotate. The rotation of the transmission shaft drives the drive wheel to rotate. The rotation of the drive wheel collects the tension wire and pulls the placement plate to the right on the slide rail to achieve traction treatment for the patient. This helps to keep the fracture ends in the correct alignment and promotes rapid fracture healing.

[0015] 2. In this utility model, when it is necessary to adjust the height of the traction frame, the handle is turned and the rotating bar and threaded rod are rotated. The rotation of the threaded rod causes multiple sliding blocks to move towards the center and push the push bar to rotate. The rotation of the push bar pushes the traction frame to rise. When it is necessary to lower the height, the reverse is true, thus lowering the height, thereby realizing the rapid adjustment of the traction frame height and improving work efficiency.

The rotation of the threaded rod 207 causes multiple sliding blocks 206 to move towards the center. The movement of the sliding blocks 206 pushes the push bar 205 to rotate, which in turn raises the traction frame. When the height needs to be lowered, turn the handle 209 in the opposite direction to rotate the threaded rod 207 and cause the sliding blocks 206 to move outward, thus lowering the height of the traction frame. This allows for rapid adjustment of the traction frame height and improves work efficiency.
