Description

Technical Field

[0001] The present invention belongs to the technical field of orthopedic rehabilitation, and particularly relates to a trauma traction and stretching device for orthopedics. Background Technique

[0002] A trauma traction and stretching device for orthopedics is a medical device used for the postoperative recovery of orthopedic traumas. Its purpose is to help the patient's skeletal and muscular systems recover normal functions by providing appropriate traction force. This device usually includes multiple components, such as a support frame, a lifting mechanism, a stretching mechanism, etc., to adapt to the needs of different patients, provide stable traction force, and help the stretched area of the repaired bone to perform stretching training, solve the problems of scar contracture and tendon contracture, thereby accelerating the rehabilitation process.

[0003] In the field of orthopedic rehabilitation treatment, a trauma traction and stretching device is an important tool to help patients recover limb functions. However, the current trauma traction and stretching devices for orthopedics on the market have certain limitations. Especially when stretching and traction are performed on the legs, it is often impossible to effectively exercise the joints of the ankle area synchronously. This deficiency in design directly leads to the situation that during the use process, patients can only focus on the rehabilitation training of a single area, while ignoring the synchronous improvement of the flexibility and strength of the ankle joint, thus affecting the overall rehabilitation effect and the functionality of the device. Summary of the Invention

[0004] The purpose of the present invention is to provide a trauma traction and stretching device for orthopedics to solve the problem that the existing trauma traction and stretching devices for orthopedics cannot exercise the joints of the ankle area synchronously during leg stretching and traction as mentioned in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A trauma traction and stretching device for orthopedics, comprising:

[0007] An installation base;

[0008] A seat cushion mechanism, which is arranged at the top of the installation base;

[0009] A traction mechanism, which is installed outside the seat cushion mechanism;

[0010] A stretching mechanism, which is arranged at the top of the installation base. The stretching mechanism includes a fixed seat, a rotating shaft and a connecting seat. A rotating shaft is arranged on the outer side wall of the fixed seat, and a connecting seat is rotatably connected to the outside of the rotating shaft. A sleeve seat is arranged above the connecting seat, and a foot support plate is arranged above the sleeve seat.

[0011] Preferably, the rotating shafts are arranged around the fixed seat, and a plurality of connecting seats are arranged outside the fixed seat through the rotating shafts. The top of the foot support plate is provided with anti-slip grooves, and a limit buckle is arranged outside the foot support plate.

[0012] Preferably, a limit mechanism is arranged inside the stretching mechanism, and a movable mechanism is connected to the top of the limit mechanism.

[0013] Preferably, the seat cushion mechanism includes a support rod, a backrest plate and a lying cushion. The support rod is fixedly connected to the outside of the installation base by screws. A backrest plate is fixedly connected to the outside of the support rod. A lying cushion is installed on the top of the backrest plate, and the lying cushion is fixedly connected to the outside of the backrest plate by screws.

[0014] Preferably, the traction mechanism includes a rotating seat, a mounting rod and a first movable seat. The rotating seat is arranged on the outside of the support rod. A mounting rod is fixedly connected to the outside of the rotating seat. A first movable seat is fixedly installed on the outside of the mounting rod. A limit clamping wheel is fixedly connected to the bottom end of the mounting rod. A hinge rod is rotatably connected inside the first movable seat. The bottom end of the hinge rod is rotatably connected to a movable rod. A stretching spring is installed on the outer side wall of the movable rod. A second movable seat is installed at the top end of the movable rod.

[0015] Preferably, the second movable seat is fixedly installed at the bottom end of the support rod. The movable rod is rotatably connected to the second movable seat. One end of the stretching spring is fixedly connected to the inside of the support rod. The rotating seat is rotatably connected to the support rod. Two groups of limit wheels are horizontally arranged on the limit clamping wheel.

[0016] Preferably, the limit mechanism includes a housing, a limit insertion rod and a first compression spring seat. The housing is rotatably connected to the outside of the connecting seat. A limit insertion rod is arranged on the outside of the housing. A first compression spring seat is installed inside the housing. A second compression spring seat is installed on the top of the first compression spring seat. A limit hole is opened on the outer side of one side of the second compression spring seat.

[0017] Preferably, the limit insertion rod is inserted into the limit hole, and the top of the second compression spring seat is sleeved on the outside of the sleeve seat.

[0018] Preferably, the movable mechanism includes a connecting sleeve seat, a sleeve ring and a rolling ball. The connecting sleeve seat is sleeved on the outside of the sleeve seat. A sleeve ring is fixedly connected to the top of the connecting sleeve seat. A rolling ball is inserted into the sleeve ring. A connecting plate is fixedly connected to the top of the rolling ball.

[0019] Preferably, the rolling ball is rotatably connected at multiple angles inside the sleeve ring. The top of the connecting plate is fixedly connected to the bottom end of the foot support plate. The rolling ball is a sphere, and the sleeve ring is a hollow hemispherical body.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) By setting the fixed seat, rotating shaft, connecting socket and collar, after the patient places the leg inside the limit clamping wheel, the leg can be stretched through the traction mechanism. During this process, the exercise for the ankle can be achieved by applying downward pressure to the foot support plate and ankle movement. Specifically, the downward pressure of the foot support plate and ankle movement will cause the rolling ball to rotate within the collar, thereby allowing the foot support plate to rotate at multiple angles. This design not only facilitates the movement of the ankle but also realizes the control of the downward pressure at different angles of the foot support plate through the limit mechanism. In addition, since each connecting seat is connected to the fixed seat through a rotating shaft, the foot support plate can perform stretching activities in the horizontal direction, further promoting the stretching exercise of the thigh. This device greatly improves the operability of the patient during the stretching traction process, making the rehabilitation training more comprehensive and effective.

[0022] (2) By setting the outer shell, limit insertion rod, first spring seat and limit hole, when the limit insertion rod is pulled out, the limited state of the first spring seat inside the outer shell will be released. In this way, the first spring seat and the second spring seat can perform elastic telescopic operations simultaneously. This design enables the foot support plate to adjust different forces as needed when performing downward pressure or horizontal stretching. On the contrary, when the limit insertion rod is inserted, the first spring seat will be fixed, and at this time only the second spring seat performs elastic telescopic movement inside the outer shell. This setting is suitable for patients with less strength in stretching training. When the limit insertion rod is pulled out, the first spring seat and the second spring seat will perform elastic telescopic movement simultaneously, thereby increasing the force when the foot support plate moves. This mode is more suitable for patients with greater strength in stretching training. Through such a mechanism, the device can flexibly adjust the training intensity according to the rehabilitation needs of the patient, meeting the rehabilitation requirements at different stages.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to Figures 1-6 As shown, an orthopedic trauma traction and stretching device includes:

[0033] Installation base 1;

[0034] Seat cushion mechanism 2, and the seat cushion mechanism 2 is arranged at the top of the installation base 1;

[0035] Traction mechanism 3, and the traction mechanism 3 is installed outside the seat cushion mechanism 2;

[0036] The stretching mechanism 4 is arranged at the top of the mounting base 1. The stretching mechanism 4 includes a fixed seat 401, a rotating shaft 402 and a connecting seat 403. The rotating shaft 402 is arranged on the outer side wall of the fixed seat 401. The connecting seat 403 is rotatably connected to the outside of the rotating shaft 402. A sleeve seat 404 is arranged above the connecting seat 403, and a foot support plate 405 is arranged above the sleeve seat 404. The rotating shaft 402 is arranged around the fixed seat 401. A plurality of connecting seats 403 are arranged outside the fixed seat 401 through the rotating shaft 402. Anti-slip grooves are formed at the top of the foot support plate 405, and a limit buckle is arranged outside the foot support plate 405. A limit mechanism 5 is arranged inside the stretching mechanism 4, and a movable mechanism 6 is connected to the top of the limit mechanism 5.

[0037] Specifically, by rotating the connecting seat 403 on the rotating shaft 402, the limit mechanism 5 can be horizontally rotated. Thus, when the patient is performing thigh stretching exercises, the limit mechanism 5 can rotate at an angle, realizing multi-directional movement of the foot support plate 405 in the front, back, left and right directions, and realizing stretching of the thigh and stretching of the ankle.

[0038] As can be seen from the above, when the patient's leg is inserted into the inside of the limit clamping wheel 304, the leg can be tractionally stretched through the traction mechanism 3. At this time, when performing ankle stretching exercises on the patient, by pressing down the foot support plate 405 and moving the ankle, the rolling ball 603 can move and rotate inside the sleeve 602, realizing multi-angle rotation of the foot support plate 405, facilitating the movement of the patient's ankle. With the setting of the limit mechanism 5, the downward pressure of the foot support plate 405 can be controlled at different angles, and each connecting seat 403 is rotatably connected to the outside of the fixed seat 401 through the rotating shaft 402, so that the horizontal stretching movement of the foot support plate 405 can be realized, and the thigh of the patient can be stretched and trained.

[0039] Reference Figure 2 and Figure 4As shown in the figure, the seat cushion mechanism 2 includes a support rod 201, a backrest plate 202 and a reclining cushion 203. The support rod 201 is fixedly connected to the outside of the mounting base 1 by screws. A backrest plate 202 is fixedly connected to the outside of the support rod 201. A reclining cushion 203 is installed at the top of the backrest plate 202. The reclining cushion 203 is fixedly connected to the outside of the backrest plate 202 by screws. The traction mechanism 3 includes a rotating seat 301, a mounting rod 302 and a first movable seat 303. The rotating seat 301 is arranged on the outside of the support rod 201. A mounting rod 302 is fixedly connected to the outside of the rotating seat 301. A first movable seat 303 is fixedly installed on the outside of the mounting rod 302. A limiting clamping wheel 304 is fixedly connected to the bottom end of the mounting rod 302. A hinge rod 305 is rotatably connected inside the first movable seat 303. The bottom end of the hinge rod 305 is rotatably connected to a movable rod 306. A tension spring 307 is installed on the outer side wall of the movable rod 306. A second movable seat 308 is installed at the top of the movable rod 306. The second movable seat 308 is fixedly installed at the bottom end of the support rod 201. The movable rod 306 is rotatably connected to the second movable seat 308. One end of the tension spring 307 is fixedly connected to the inside of the support rod 201. The rotating seat 301 is rotatably connected to the support rod 201. Two groups of limiting wheels are horizontally arranged on the limiting clamping wheel 304.

[0040] Specifically, when the patient performs leg stretching training, first, the patient inserts the leg into the inside of the limiting clamping wheel 304, and then raises the lower leg. After the hinge rod 305 rotates on the first movable seat 303 and the movable rod 306, the tension spring 307 can be stretched, so as to perform the lifting and stretching training of the patient's leg.

[0041] Embodiment 2:

[0042] Reference Figures 1-6 As shown in the figure, the limiting mechanism 5 includes a housing 501, a limiting insertion rod 502 and a first compression spring seat 503. The housing 501 is rotatably connected to the outside of the connecting seat 403. A limiting insertion rod 502 is arranged on the outside of the housing 501. A first compression spring seat 503 is installed inside the housing 501. A second compression spring seat 505 is installed at the top of the first compression spring seat 503. A limiting hole 504 is opened on the outer side of one side of the second compression spring seat 505. The limiting insertion rod 502 is inserted into the inside of the limiting hole 504. The top of the second compression spring seat 505 is sleeved on the outside of the sleeve seat 404. The moving mechanism 6 includes a connecting sleeve seat 601, a sleeve ring 602 and a rolling ball 603. The connecting sleeve seat 601 is sleeved on the outside of the sleeve seat 404. A sleeve ring 602 is fixedly connected to the top of the connecting sleeve seat 601. A rolling ball 603 is inserted into the inside of the sleeve ring 602. The top of the rolling ball 603 is fixedly connected to a connecting plate 604. The rolling ball 603 is rotatably connected at multiple angles inside the sleeve ring 602. The top of the connecting plate 604 is fixedly connected to the bottom end of the foot support plate 405. The rolling ball 603 is a sphere, and the sleeve ring 602 is a hollow hemisphere.

[0043] Specifically, by inserting the limit insertion rod 502 into the limit hole 504, the operation between the first spring seat 503 and the second spring seat 505 can be used separately or simultaneously, and the pressure on the limiting mechanism 5 can be adjusted according to different users.

[0044] As can be seen from the above, when the limit insertion rod 502 is pulled out, the limit of the first spring seat 503 inside the housing 501 is released, so that the first spring seat 503 and the second spring seat 505 can perform elastic telescopic operations simultaneously. Therefore, when the foot support plate 405 is pressed down or horizontally stretched, different strengths can be adjusted. When the limit insertion rod 502 is inserted, the first spring seat 503 is limited. At this time, only the second spring seat 505 performs elastic telescoping inside the housing 501, which is suitable for patients with relatively small stretching training strength. After the limit insertion rod 502 is pulled out, the second spring seat 505 and the first spring seat 503 perform elastic telescoping simultaneously, improving the strength when the foot support plate 405 moves, which is suitable for patients with relatively large stretching training strength.
