Description

Technical Field

[0001] This utility model relates to the field of positioning pad technology, specifically a positioning pad with adjustable curvature. Background Technology

[0002] Surgical positioning pads are medical devices used in operating rooms and placed on operating tables. Currently, there are many types of materials used for surgical positioning pads in clinical practice, but their main function is to prevent pressure sores and bedsores caused by prolonged surgical procedures, thus providing patients with a certain degree of comfort. In addition, surgical positioning pads are also crucial for positioning patients during surgery. Furthermore, using surgical positioning pads can prevent pressure on the patient's limbs and joints, which can lead to surgical complications.

[0003] As disclosed in the patent announcement number CN221787174U, an adjustable curvature positioning pad includes a base. A head support, a neck support, and a thoracic spine support are sequentially arranged on the top of the base from one end to the other. A first drive motor is provided between the head support and the base. The first drive motor is driven and connected to the head support through a first transmission mechanism and a second transmission mechanism. A second drive motor is provided between the neck support and the base. The second drive motor is driven and connected to the neck support through a third transmission mechanism.

[0004] Although it allows medical staff to control the position of the headrest and the curvature of the neckrest by controlling the first drive motor and the second drive motor, the curvature of the neckrest can be adjusted, and the headrest can also be raised, lowered and moved forward and backward as needed to better fit the curves of the human neck, head and back, avoid pressure sores on the patient's head, neck or back, and improve the patient's comfort.

[0005] However, this does not solve the problem that existing positioning pads of this type are generally not conducive to convenient control and adjustment of the bending angle for curvature support, are not easy to connect smoothly at the bending angle, and the burr and sharp edge structure can easily cause scratches to the body, which greatly affects the stability of mechanical transmission and the comfort of lying on the positioning pad. Utility Model Content

[0006] The purpose of this invention is to provide a body positioning pad with adjustable curvature to solve the problems mentioned in the background art, such as the inconvenience of controlling and adjusting the curvature angle for curvature support, the difficulty of smooth connection at the curvature angle, the burr and sharp edge structure that can easily scratch the body, the impact on the stability of mechanical transmission, and the impact on the comfort of lying down on the body positioning pad.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable curvature positioning pad, comprising a placement box and a support base. The support base is installed inside the placement box. Multiple sets of arc-shaped plates with equal spacing are arranged at the top of the placement box above the support base. A right arc-shaped hook is installed at one end of each arc-shaped plate, and a left arc-shaped hook is installed at the other end of each arc-shaped plate. A limit rod is provided between the right arc-shaped hook of one set of arc-shaped plates and the left arc-shaped hook of another set of arc-shaped plates. A threaded long sleeve is installed at the bottom end of each arc-shaped plate. A threaded long column is provided at the bottom end of each threaded long sleeve. A ball head is installed at the bottom end of each threaded long column. A lifting block is provided outside the support base below the ball head. Threaded sleeves are symmetrically installed at the bottom end of each lifting block.

[0008] Optionally, each threaded sleeve has a threaded rod inside, and both ends of the threaded rod extend to the outside of the threaded sleeve.

[0009] Optionally, the surface of the threaded long column is fitted with a threaded cap, and the threaded cap is threadedly connected to the threaded long column, and the threaded long column is threadedly connected to the threaded long sleeve.

[0010] Optionally, a servo motor is installed at the top of the support base below the threaded rod, and the output end of the servo motor is connected to the threaded rod.

[0011] Optionally, a positioning block is installed at the top of each lifting block, and a left spherical sleeve is installed at the top of each positioning block, with the left spherical sleeve being movably connected to the ball head.

[0012] Optionally, each of the positioning blocks is equipped with a clamping block on its outer wall, and each clamping block is equipped with a right spherical sleeve at its top, with the right spherical sleeve being movably connected to the ball head.

[0013] Optionally, a locking bolt is provided on the outer wall of the positioning block, and the locking bolt extends into the interior of the clamping block.

[0014] Optionally, a handle is installed at the end of the locking bolt away from the positioning block, and the handle is fixedly connected to the locking bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the positioning pad not only realizes the convenient control and adjustment of the bending angle for curvature support, facilitates smooth connection at the bending angle, avoids the generation of burr and sharp corner structures, improves the stability during mechanical transmission, but also improves the comfort when lying on the positioning pad.

[0016] A servo motor drives a threaded rod to rotate, which in turn drives a threaded sleeve to move a lifting block. The lifting block is height-adjustable. The lifting block, via a positioning block, drives the left and right spherical sleeves for height adjustment. The left spherical sleeve then drives the ball head, threaded column, threaded sleeve, and curved plate for height adjustment, facilitating the height adjustment of the curved plate. The servo motor controls the lifting height of the lifting block, creating a curved structure with different heights between multiple curved plates. The multiple curved plates are connected by a right and left curved hook. A limiting rod provides support for the right and left curved hooks, facilitating a smooth connection between the multiple curved plates. This allows for convenient control and adjustment of the bending angle of the positioning pad, providing curvature support and smooth connection at bending angles. It also avoids the formation of burrs and sharp edges, improving comfort when lying down on the positioning pad. Attached Figure Description

[0032] Please see Figure 1-6 An embodiment of this utility model provides: a body positioning pad with adjustable curvature, including a placement box 1 and a support base 2. The support base 2 is installed inside the placement box 1. Multiple sets of arc-shaped plates 16 with equal spacing are provided at the top of the placement box 1 above the support base 2. A right arc hook 14 is installed at one end of each arc plate 16, and a left arc hook 18 is installed at the other end of each arc plate 16. A limit rod 17 is provided between the right arc hook 14 of one set of arc plates 16 and the left arc hook 18 of another set of arc plates 16. A threaded long sleeve 15 is installed at the bottom end of each arc plate 16. A threaded long column 12 is provided at the bottom end of each threaded long column 12. A ball head 11 is installed at the bottom end of each threaded long column 12. A lifting block 6 is provided on the outside of the support base 2 below the ball head 11. Threaded sleeves 5 are symmetrically installed at the bottom end of each lifting block 6.

[0033] The threaded sleeve 5 is provided with a threaded rod 4 inside, and both ends of the threaded rod 4 extend to the outside of the threaded sleeve 5. The surface of the threaded long column 12 is fitted with a threaded cap 13, and the threaded cap 13 is threadedly connected to the threaded long column 12. The threaded long column 12 is also threadedly connected to the threaded long sleeve 15.

[0034] Servo motors 3 are installed at the top of the support base 2 below the threaded rod 4, and the output end of the servo motor 3 is connected to the threaded rod 4.

[0035] By having personnel lie on the surface of multiple sets of curved plates 16, when bending support is required, multiple sets of servo motors 3 are activated. The servo motors 3 drive the threaded rods 4 to rotate. Under the meshing of the threaded rods 4 and threaded sleeves 5, the threaded sleeves 5 drive the lifting blocks 6 to move. The lifting blocks 6 are height-adjustable. The lifting blocks 6 drive the left spherical sleeves 19 and right spherical sleeves 10 to adjust their height via the positioning blocks 7. The left spherical sleeve 19 drives the ball head 11, the threaded long column 12, the threaded long sleeve 15, and the curved plates 16 to adjust their height, thus facilitating the height adjustment of the curved plates 16. The servo motor 3 controls the lifting height of the lifting block 6 to achieve different heights between multiple sets of arc plates 16 to form a bending structure. The multiple sets of arc plates 16 are engaged by the right arc hook 14 and the left arc hook 18. The limiting rod 17 provides limiting support for the right arc hook 14 and the left arc hook 18 to facilitate smooth connection between multiple sets of arc plates 16. This enables convenient control and adjustment of the bending angle of the positioning pad for curvature support, facilitates smooth connection at the bending angle, avoids the generation of burr and sharp corner structures, and improves the comfort of lying on the positioning pad.

[0036] Each lifting block 6 has a positioning block 7 installed at its top, and each positioning block 7 has a left spherical sleeve 19 installed at its top, and the left spherical sleeve 19 is movably connected to the ball head 11. Each positioning block 7 has a clamping block 8 installed on its outer wall, and each clamping block 8 has a right spherical sleeve 10 installed at its top, and the right spherical sleeve 10 is movably connected to the ball head 11.

[0037] A locking bolt 9 is provided on the outer wall of the positioning block 7, and the locking bolt 9 extends into the interior of the clamping block 8. A handle 20 is installed on the end of the locking bolt 9 away from the positioning block 7, and the handle 20 is fixedly connected to the locking bolt 9.

[0038] By manually rotating the handle 20, the handle 20 drives the locking bolt 9 to rotate. The locking bolt 9 presses against the positioning block 7 and the clamping block 8, thereby pressing against the left spherical sleeve 19, the ball head 11, and the right spherical sleeve 10. This controls and adjusts the movement of the ball head 11, preventing it from being clamped too tightly or too loosely, which would affect the bending effect of the arc plate 16. The threaded long column 12 and the threaded long sleeve 15 are connected by a threaded movable connection. The threaded cap 13 locks the threaded long column 12 and the threaded long sleeve 15 again, making it easy to adjust the relative distance between the threaded long column 12 and the threaded long sleeve 15, thus facilitating structural adjustment. This achieves reliable mechanical transmission when the positioning pad bends, improving the stability of the mechanical transmission.

[0039] The working principle of this invention involves an external power supply. First, a person lies on the surface of multiple sets of curved plates 16. A servo motor 3 drives a threaded rod 4 to rotate, and a lifting block 6 adjusts its height. The lifting block 6, via a positioning block 7, drives the left spherical sleeve 19 and the right spherical sleeve 10 for height adjustment. The left spherical sleeve 19 then drives the ball head 11, the threaded long column 12, the threaded long sleeve 15, and the curved plates 16 for height adjustment. This facilitates height adjustment of the curved plates 16. The lifting height of the lifting block 6 is controlled by the servo motor 3, achieving a curved structure with different heights among the multiple sets of curved plates 16, thus ensuring smooth movement between them. The handle 20 drives the locking bolt 9 to rotate, and the locking bolt 9 presses against the positioning block 7 and the clamping block 8 to press against the left spherical sleeve 19, the ball head 11 and the right spherical sleeve 10, thereby controlling and adjusting the range of motion of the ball head 11 to prevent the ball head 11 from being clamped too tightly or too loosely, which would affect the bending effect of the arc plate 16. The threaded long column 12 and the threaded long sleeve 15 are connected by a threaded movable connection. The threaded cap 13 locks the threaded long column 12 and the threaded long sleeve 15 again, so as to facilitate the adjustment of the relative distance between the threaded long column 12 and the threaded long sleeve 15, and to facilitate the adjustment of the structure to complete the use of the positioning pad.
