Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a split-leg traction structure. Background Technology

[0002] In the medical field, especially in rehabilitation therapy and orthopedic surgical assistance, leg traction is frequently required for patients. Traditional leg traction devices often have structural design shortcomings, such as difficulty in ensuring traction accuracy, inability to flexibly adjust to the patient's specific needs, and the potential for discomfort or even secondary injury during use. Furthermore, existing leg traction structures need improvement in stability and reliability, failing to adequately meet the diverse needs of clinical practice. Therefore, developing a novel, structurally sound, and high-performance leg traction structure is of significant practical importance. Summary of the Invention

[0003] The purpose of this invention is to provide a leg-split traction structure to solve the problems of poor traction accuracy, insufficient flexibility, poor stability and reliability in the prior art, so as to provide patients with more accurate, safer and more comfortable leg-split traction treatment.

[0004] The split-leg traction structure of the present invention includes a main support frame with a frame structure. A first traction unit is provided on the main support frame. The first traction unit includes a first transverse front support, a first transverse rear support, a first sliding frame, a second sliding frame, and a first push rod motor. The first transverse front support is transversely fixedly mounted on the main support frame, and the first transverse rear support is transversely positioned between the first and second sliding frames. One end of the first push rod motor is connected to the first transverse front support, and the other end is connected to the first transverse rear support. The first and second sliding frames are respectively connected to the two side frames of the main support frame via sliding components.

[0005] Furthermore, the split-leg traction structure also includes a second traction unit, which is positioned above the first traction unit. The second traction unit includes a second lateral front support, a second lateral rear support A, a second lateral rear support B, a third sliding frame, a fourth sliding frame, a fifth sliding frame, a sixth sliding frame, a second push rod motor, a third push rod motor, and a connecting plate. The two ends of the second lateral front support are perpendicularly connected to the front ends of the first and second sliding frames, respectively. The two ends of the second lateral rear support A are perpendicularly connected to the third and fourth sliding frames, respectively. The two ends of the second lateral rear support B are perpendicularly connected to the fifth and sixth sliding frames, respectively. One end of the second push rod motor is connected to the second lateral front support, and the other end is connected to the second lateral rear support A. One end of the third push rod motor is connected to the second lateral front support, and the other end is connected to the second lateral rear support B. The second and third push rod motors are arranged horizontally side-by-side. The connecting plate is vertically set in the middle of the second transverse front bracket. The first sliding frame and the third sliding frame are connected by a sliding component. The fourth sliding frame is connected to one side of the connecting plate by a sliding component. The fifth sliding frame is connected to the other side of the connecting plate by a sliding component. The sixth sliding frame is connected to the second sliding frame by a sliding component. The second push rod motor is set between the third sliding frame and the fourth sliding frame. The third push rod motor is set between the fifth sliding frame and the sixth sliding frame.

[0006] Furthermore, in order to better monitor and control the traction force, tension and compression sensors are respectively installed between the first push rod motor and the first lateral front support, between the second push rod motor and the second lateral front support, and between the third push rod motor and the second lateral front support.

[0007] Furthermore, the leg-split traction structure also includes two movable panels, which are respectively located between the third and fourth sliding frames and between the fifth and sixth sliding frames. The movable panels can assist patients in adjusting their posture and improve comfort.

[0008] Furthermore, traction frames are installed between the third and fourth sliding frames, and between the fifth and sixth sliding frames, respectively. These traction frames are used to better fix the patient's lower limbs and achieve precise traction.

[0009] Furthermore, the aforementioned sliding assembly includes a slide rail and a slider, with the slider slidably mounted on the slide rail. The sliding assembly enables each sliding frame to slide smoothly and steadily.

[0010] Furthermore, to facilitate the movement of the entire split-leg traction structure, pulleys are provided at the bottom of the main support frame.

[0011] Beneficial effects: This invention, by setting up multiple traction units, can achieve precise traction on different parts of the patient's lower limbs with varying intensities, greatly improving the effectiveness and flexibility of traction therapy. The tension and pressure sensors can monitor the traction force in real time, avoiding injury to the patient due to excessive or insufficient traction force, thus improving the safety and reliability of the traction process. The movable panel and traction frame enhance the fixation effect on the patient's lower limbs, further ensuring the accuracy of traction. The sliding component adopts a slide rail and slider structure, making the sliding between components smoother and more stable, reducing friction and jamming, and extending the service life of the equipment.
