Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a pressure-balanced and adjustable orthopedic traction support device. Background Art

[0002] In the field of medical device technology, orthopedic traction support devices, as key equipment for rehabilitation treatment, have been widely studied and applied in recent years. Traditional orthopedic traction support devices mainly rely on mechanical structures to achieve limb traction of patients, and adjust the traction force and direction through simple lever principles or spiral mechanisms. With the continuous advancement of medical technology, electric traction supports have gradually emerged, using electric motors to achieve more precise and flexible traction control. Such devices are usually equipped with electric telescopic rods, angle adjusters and other components, and can be personalized according to the patient's specific conditions and treatment needs. Settings.

[0003] Although the existing electric orthopedic traction support devices have improved the accuracy and convenience of traction therapy to a certain extent, there are still some shortcomings, especially in terms of pressure balance and angle adaptive adjustment. Specifically, traditional devices often use a single mechanical structure or a simple electric control system to achieve traction force adjustment. This adjustment method often ignores factors such as changes in patient position, differences in muscle tension, and bone structure characteristics that may occur during traction, resulting in uneven traction force distribution, which can easily cause patient discomfort or even secondary injury. In addition, existing devices usually rely on manual operation or preset programs for angle adjustment, lack the ability to respond to real-time feedback from patients, and have difficulty in achieving dynamic adaptive adjustment of traction angles, which not only affects the effect of traction therapy, but also increases the difficulty of operation for medical staff and the treatment risk for patients.

[0038] Embodiment three:

[0039] See also Figures 1 to 6 As shown, a controller 33 is fixedly connected to the top of the mounting base plate 1 near the back of the mounting sleeve 5, a servo motor 34 is fixedly connected to the inner wall of the mounting sleeve 5, a driving rod 35 is installed at the output end of the servo motor 34, a threaded rod 36 is fixedly connected to the top of the driving rod 35, a threaded sleeve rod 37 is threadedly connected to the surface of the threaded rod 36, a seat plate 38 is fixedly connected to the top of the threaded sleeve rod 37, and a handle 39 is fixedly connected to the top of the seat plate 38.

[0042] See also Figures 1 to 6 As shown, continuous traction therapy is required after surgery for right lower limb tibial fracture to maintain the stability of the fracture end and promote bone reduction and healing. Traditional traction devices have problems such as inconvenient adjustment and poor pressure balance, which can easily cause patient discomfort or poor traction effect. The use of this pressure-balanced adjustable orthopedic traction support device can accurately control the traction force and angle, thereby improving the comfort and safety of treatment.

[0043] Push the device to the side of the bed using the universal wheels and lock the position, and adjust the installation base to the level.

[0044] The servo motor is started through the controller to drive the threaded rod to rotate to lower the height of the seat board, thereby helping the patient to sit steadily on the seat board, and the handle helps the patient to fix the body position.

[0045] Operate the second electric telescopic rod to extend the foot rest to the sole of the patient's foot, and use the first wrapping belt to fix the foot; use the third electric telescopic rod to adjust the leg rest to below the calf, and use the second wrapping belt to fix the leg.

[0046] The controller starts the first electric telescopic rod to extend horizontally, driving the connecting column and the fixing frame to adjust the traction direction. At the same time, the control rod is linked to the installation clamp to fine-tune the angle so that the traction force acts along the fracture line.

[0047] The electric guide rail in the assembly box drives the sliding block to move, driving the U-shaped connecting pipe and the piston to synchronously adjust the air pressure of the air tanks on both sides to balance the distribution of traction force.

[0048] The cylinder pushes the piston through the output pipe to further fine-tune the air pressure. The air pressure change is transmitted to the telescopic column through the discharge pipe, dynamically adjusting the telescopic amount to ensure constant traction.

[0049] The arc-shaped positioning rod and the limit frame limit the swing range to avoid excessive traction.

[0050] According to patient feedback and imaging examination results, the electric telescopic rod and air pressure system are adjusted in real time through the controller to optimize the traction parameters.

[0051] Working principle: The installation base serves as the supporting foundation of the entire device, and its top two sides are rotatably connected with the connecting columns through fixed columns, so that the device can be adjusted at multiple angles.

[0052] The first electric telescopic rod is embedded in the connecting column, and changes the horizontal position of the connecting column through telescopic movement, thereby adjusting the traction direction.

[0053] The fixing rod and the assembly plate constitute the main frame, the sleeve frames on both sides of the assembly plate are slidably connected with the telescopic column, and the fixing clamp block at the output end of the telescopic column is hinged with the installation clamp block through the control rod to form a linkage mechanism.

[0054] When the control rod rotates, the mounting clamp drives the fixing frame to adjust the angle, so that the angle between the connecting column and the fixing frame changes dynamically, thereby realizing the precise adjustment of the traction direction.

[0055] Two gas storage tanks separated by a partition plate are arranged in the assembly box for storing compressed gas.

[0056] The electric guide rail drives the sliding block to move horizontally, driving the U-shaped connecting pipe and the pistons at both ends to slide synchronously in the gas storage tank to balance the air pressure on both sides.

[0057] The cylinder pushes the piston through the output pipe to make fine adjustments, further accurately controlling the air pressure in the air tank.

[0058] The air pressure change is transmitted to the tail end of the telescopic column through the exhaust tube, adjusting the extension and retraction amount of the telescopic column, thereby dynamically adjusting the traction force applied to the patient's limbs.

[0059] The arc-shaped positioning rod cooperates with the limit frame to limit the swing range of the connecting column and ensure stability during the traction process.

[0060] The second electric telescopic rod drives the foot rest to move longitudinally, and cooperates with the first winding belt to fix the foot; the third electric telescopic rod adjusts the height of the leg rest, and stabilizes the legs through the second winding belt to achieve segmented traction.

[0061] Universal wheels allow the unit to be moved flexibly and locked in position for easy adjustment and fixing.

[0062] The controller centrally controls the servo motor to drive the drive rod to rotate, which drives the threaded rod to rotate.

[0063] The threaded sleeve rod cooperates with the threaded rod thread to realize vertical lifting movement, thereby accurately adjusting the height of the seat plate to meet the body position requirements of different patients.

[0064] The handle provides a stable grip point for the patient, assists in adjusting the sitting position and enhances safety during traction.

[0065] Through the dual regulation of mechanical linkage and air pressure system, the device can respond to changes in traction in real time and dynamically balance the pressure.

[0066] Medical staff can adjust the parameters of the electric telescopic rod, cylinder and servo motor through the controller according to patient feedback and clinical needs, optimize traction force and angle, and ensure treatment effectiveness.
