Description

Technical Field

[0001] This utility model specifically relates to a rotatable interventional surgical hand support device, belonging to the technical field of surgical hand support devices. Background Technology

[0002] Interventional surgery hand support device is an auxiliary device specifically designed for interventional surgery. It is mainly used to stabilize the patient's upper limb or the surgeon's operating platform, ensuring the accuracy and safety of the surgery, and reducing patient limb movement and surgeon's operation error, thereby improving the success rate of the surgery and patient comfort.

[0003] In current interventional surgeries, when the elbow joint needs to be fixed posteriorly to a support plate as a fulcrum while the distal forearm and wrist are raised for procedures such as radial artery puncture, angiography, or catheter placement, the patient's arm is forced to maintain a passive "elbow-supported, wrist-loose" position. Elderly patients, due to muscle atrophy and insufficient joint stability, are prone to arm weakness and tremors from maintaining this position for extended periods. This necessitates the surgeon or assistant to continuously support the hand for stability, which not only consumes medical manpower but also increases the risk of puncture failure due to swaying. If gauze rolls or medical pads are used for support, their height is not adjustable, requiring repeated adjustments and replacements, thus prolonging preoperative preparation time and affecting surgical efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a rotatable interventional surgical hand support device. It includes a support arm, one end of which is equipped with a damping shaft. A support plate is rotatably connected to one end of the support arm via the damping shaft. Sliding grooves are provided on both sides of the support plate. Multiple sets of first and second sliding plates are slidably and detachably connected inside the sliding grooves. Each of the first and second sliding plates has a receiving groove inside, and a support plate is slidably connected inside the receiving groove. One end of the support plate is connected to a screw threaded through the interior of the first and second sliding plates. A strap is installed on one side of each of the first sliding plates, and a lifting component is installed on one side of each of the second sliding plates.

[0005] The lifting assembly includes a first connecting shaft and a mounting bracket. The first connecting shaft is mounted on one side of the second slide plate. A first worm gear and an adjusting arm are respectively mounted on one end of the first connecting shaft. The mounting bracket is fixed on one side of the second slide plate, and a first worm gear that meshes with the first worm gear is mounted on the mounting bracket.

[0006] The lifting assembly further includes a second connecting shaft and a second worm gear. One end of the second connecting shaft is mounted on the adjusting arm, and the other end of the second connecting shaft is connected to a lifting plate. The second worm gear is rotatably mounted on the adjusting arm, and a second worm wheel that meshes with the second worm gear is installed at the middle end of the second connecting shaft.

[0007] Both the support plate and the lifting plate have Velcro straps on their inner sides, and water bags are attached to both the support plate and the lifting plate by Velcro straps.

[0008] The water bag has a water pipe at one end, and a valve is installed on the water pipe.

[0009] A rubber pad is provided on the bottom side of the support arm. Beneficial effects

[0010] The angle of the support plate is adjusted by the damping shaft to suit the surgeon's position. The screw is loosened or tightened according to the patient's arm length to lock / release the first and second sliding plates. The position of the strap can be adjusted by sliding the first sliding plate to achieve arm length adaptation. When the patient's elbow is placed at the fulcrum in the middle of the support plate, the first worm gear is rotated to drive the worm wheel to rotate the adjusting arm, which in turn moves the second sliding plate to adjust the height and horizontal extension of the support plate. At the same time, the angle of the support plate is finely adjusted by rotating the second worm gear so that its inner side fits tightly against the contour of the back of the wrist, reducing local pressure that could lead to radial artery spasm or skin ischemia. This replaces manual support and can be flexibly adjusted according to the patient's arm length and support point, shortening the preoperative preparation time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-5As shown, a rotatable interventional surgical hand support device includes a support arm 1, a damping shaft 2 mounted on one end of the support arm 1, and a support plate 3 rotatably connected to one end of the support arm 1 via the damping shaft 2. Both sides of the support plate 3 have sliding grooves 4, and multiple sets of first sliding plates 5 and second sliding plates 10 are slidably and detachably connected inside the sliding grooves 4. Both the first sliding plates 5 and the second sliding plates 10 have receiving grooves 6, and a stop plate 7 is slidably connected inside the receiving grooves 6. One end of the stop plate 7 is connected to a screw 8 threaded through the interior of the first sliding plates 5 and the second sliding plates 10. A strap 9 is mounted on one side of each of the first sliding plates 5, and a lifting assembly is mounted on one side of each of the second sliding plates 10. The lifting assembly includes a first... A connecting shaft 11 and a mounting bracket 13 are provided. The first connecting shaft 11 is installed on one side of the second slide plate 10. A first worm gear 12 and an adjusting arm 15 are respectively installed on one end of the first connecting shaft 11. The mounting bracket 13 is fixed on one side of the second slide plate 10. A first worm 14 that meshes with the first worm gear 12 is installed on the mounting bracket 13. The lifting assembly also includes a second connecting shaft 16 and a second worm 18. One end of the second connecting shaft 16 is installed on the adjusting arm 15, and the other end of the second connecting shaft 16 is connected to a lifting plate 19. The second worm 18 is rotatably installed on the adjusting arm 15. A second worm gear 17 that meshes with the second worm 18 is installed in the middle of the second connecting shaft 16.

[0015] Working steps: By fixing the support arm 1 to the operating table, the angle of the support plate 3 is adjusted via the damping shaft 2 to suit the surgeon's position. Then, depending on the patient's arm length, the screw 8 is loosened or tightened to move the abutment plate 7 closer to or further from the slide groove 4, quickly locking or unlocking the first sliding plate 5 and the second sliding plate 10. By sliding the first sliding plate 5, the position of the strap 9 on the support plate 3 can be adjusted, allowing for flexible adjustment according to different patients' arm lengths. Simultaneously, when the patient's elbow is placed in the middle of the support plate 3 as a fulcrum, rotating the first worm gear 14 engages the first worm wheel 12, driving the adjusting arm 15 to rotate. This, combined with the sliding adjustment of the second sliding plate 10, allows for proper lifting. The height and horizontal extension of the support plate 19 can be adjusted to allow for flexible adjustment based on the patient's arm raising height and the position of the arm's support point. Simultaneously, by rotating the second worm gear 18, the second worm gear 18 is engaged and drives the support plate 19 to rotate, thereby adjusting the angle of the support plate 19. This allows the inner side of the support plate 19 to better conform to the contour of the patient's wrist, reducing local pressure that could lead to radial artery spasm or skin ischemia. When the support plate 19 is not needed, the second sliding plate 10 can be moved to the area of ​​the support plate 3 away from the support arm 1, and the angle of the adjusting arm 15 can be adjusted to move the support plate 19 to the area below the support plate 3, without affecting the normal use and placement of the original hand support.

[0016] Furthermore, both the support plate 3 and the lifting plate 19 have Velcro 20 on their inner sides, and water bags 21 are attached to both the support plate 3 and the lifting plate 19 via Velcro 20. One end of the water bag 21 has a water pipe with a valve. During operation, the water bag 21 is attached to the lifting plate 19 and the support plate 3 via Velcro 20, which supports quick replacement of the water bag 21. At the same time, hot or cold water can be injected into the water bag 21 through the water pipe. For example, injecting warm water in cold weather can relieve joint stiffness caused by muscle atrophy in elderly patients. Injecting cold water during long-term surgery can reduce skin sweating and maceration of the contact surface, improving intraoperative comfort. By using the water bag 21 to distribute a certain amount of pressure, it can reduce radial artery compression spasm.

[0017] Furthermore, a rubber pad is provided on the bottom side of the support arm 1; during operation, the rubber pad is used to increase the friction between the bottom side of the support arm 1 and the bed body, thereby improving the stability of the support on the bottom side of the support arm 1.
