Abstract
Description
Technical Field
[0001] This invention relates to the field of surgical instruments, and in particular to a surgical bed tray. Background Technology
[0002] In clinical practice, many surgeries require the use of surgical trays. Surgical instruments are placed on the trays for easy access by nurses and surgeons. However, the commonly used surgical trays are typically trolley-type trays with casters. Before surgery, the tray is extended to the side of the operating table or placed above the patient's head or legs, and its height is adjusted. The necessary instruments are then placed on the tray for later use. Since many surgeries require adjusting the operating table height during the procedure (e.g., prone spinal surgeries requiring raising and lowering the operating table for intraoperative fluoroscopy), the tray needs to be manually raised to prevent the patient from bumping into it, or manually adjusted to facilitate instrument access for doctors or nurses. This increases the complexity of using the tray. Furthermore, after surgery, the trolley-type tray needs to be removed and moved back to the operating table for the next use, further complicating its use.
[0003] Therefore, it is necessary to provide a technical solution for an easy-to-use operating table tray. Summary of the Invention
[0004] This invention proposes a surgical bed tray that is easy to use.

[0006] In one embodiment, the first support foot includes a first support frame, a first support rod, and a first positioning pin. The first support frame has a first insertion hole, and the first support rod is movably inserted into the first insertion hole along its own axial direction. The first positioning pin passes through the hole wall of the first insertion hole from the outer surface of the first support frame and can be detachably abutted against the first support rod. When the first positioning pin abuts against the first support rod, the first positioning pin limits the relative position between the first support rod and the first support frame.
[0007] In one embodiment, the first support frame has a first threaded hole communicating with the first insertion hole, the first positioning pin is threadedly connected to the first threaded hole, and the circumferential sidewall of the first support rod has a plurality of limiting grooves for cooperating with the inner end of the first positioning pin, and the limiting grooves are arranged sequentially along the axial direction of the first support rod.

When the second positioning pin abuts against the second support rod, the relative position of the second support rod and the second support frame is defined by the second positioning pin.
[0010] In one embodiment, the second support frame has a second threaded hole that communicates with the second insertion hole, the second positioning pin is threadedly connected to the second threaded hole, and the circumferential sidewall of the second support rod has a plurality of limiting grooves for cooperating with the inner end of the second positioning pin, and each of the limiting grooves is arranged sequentially along the axial direction of the second support rod.
[0011] In one embodiment, the second support frame includes a second horizontal rod and a second vertical rod; the second vertical rod is connected to the second horizontal rod; the second insertion hole is opened inside the second vertical rod and extends along the axial direction of the second vertical rod; the second fastener is provided on the second horizontal rod to detachably connect the second horizontal rod to the side of the operating table.
[0012] In one embodiment, the support plate includes a support plate, a sliding assembly, and a first hinge plate; the first hinge plate is slidably connected to the support plate via the sliding assembly, and the sliding direction of the first hinge plate is parallel to the parallel direction of the first support foot and the second support foot; the first support foot is hinged to the first hinge plate.

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0019] Please see Figure 1 This embodiment discloses a surgical bed tray, including a tray plate, a retractable first support leg 20, a retractable second support leg 30, and a snap-fit assembly; the first support leg 20 and the second support leg 30 are arranged side by side and spaced apart, and the first support leg 20 can be hinged to the tray plate by rotating inward by 90 degrees. Specifically, as shown... Figure 1 As shown, the first support leg 20 rotates 90 degrees in the F1 direction; the second support leg 30 can rotate outwards 270 degrees and is hinged to the support plate, specifically, as shown... Figure 1 As shown, the second support leg 30 is rotated 270 degrees along the F2 direction; the latching assembly includes a first latching member 60 for detachably connecting the first support leg 20 to one side of the operating table 70 and a second latching member for detachably connecting the second support leg 30 to the other side of the operating table 70.
[0020] In one usage scenario, when storing the tray, firstly, the first support leg 20 can be removed from the operating table 70. Then, the first support leg 20 can be rotated inward by 90 degrees, folding it to the bottom of the tray. Next, the tray can be rotated 270 degrees around the second support leg 30, folding it to one side of the second support leg 30. This allows the surgical tray to be folded and stored on one side of the operating table 70. For the next use, simply unfold the surgical tray and connect the first support leg 20 to the operating table 70. In another usage scenario… In this embodiment, when storing the tray, the second support leg 30 is removed from the operating table 70, then the second support leg 30 is rotated outward by 270 degrees, folding the second support leg 30 to the top surface of the tray. Finally, the tray is rotated 90 degrees around the first support leg 20, folding the tray to one side of the first support leg 20. Therefore, compared with the prior art, this embodiment saves the process of moving the operating table tray when using it, and the process of folding and unfolding the operating table tray is simple and quick, thus improving the ease of use of the operating table tray.
[0021] The structure of the tray, the first support leg 20, and the second support leg 30 will be described next.
[0022] Please combine Figure 1 and Figure 2 In this embodiment, the support plate includes a support plate 10, a sliding assembly, and a first hinge plate 50. The support plate 10 is used to hold instruments used during the surgical procedure. The first hinge plate 50 is slidably connected to the support plate 10 via the sliding assembly. The sliding direction of the first hinge plate 50 is parallel to the parallel direction of the first support leg 20 and the second support leg 30. Here, the parallel direction refers to... Figure 1 As shown in direction F3, the first support leg 20 is hinged to the first hinge plate 50. In practical applications, when the first hinge plate 50 is slid, the first support leg 20 and the first hinge plate 50 move together, thus adjusting the distance between the first support leg 20 and the second support leg 30. This allows the first support leg 20 and the second support leg 30 to be used on operating tables 70 of different widths, thereby improving the applicability of this embodiment.
[0023] In this embodiment, the first support foot 20 includes a first support frame, a first support rod 22, and a first positioning pin 23.
[0024] The first support frame has a first insertion hole. The first support rod 22 is movably inserted into the first insertion hole along its own axial direction. The movement of the first support rod 22 within the first insertion hole corresponds to the extension and retraction of the first support leg 20. Specifically, the first support frame includes a first horizontal rod 212 and a first vertical rod 211. The first horizontal rod 212 is used to connect to the operating table 70. The first vertical rod 211 is connected to the first horizontal rod 212, and the first vertical rod 211 and the first horizontal rod 212 are arranged in a T-shape. The first insertion hole is opened inside the first vertical rod 211 and extends along the axial direction of the first vertical rod 211. The upper end of the first support rod 22 is provided with a second hinge plate 24. Preferably, the second hinge plate 24 is welded to the first support rod 22 and hinged to the first hinge plate 50. The second hinge plate 24 and the first hinge plate 50 can be hinged by a self-locking hinge. The self-locking hinge is existing technology, so the structure of the self-locking hinge will not be described here.
[0025] The first positioning pin 23 extends from the outer surface of the first support frame through the wall of the first insertion hole and can detachably abut against the first support rod 22. When the first positioning pin 23 abuts against the first support rod 22, the first positioning pin 23 limits the relative position of the first support rod 22 and the first support frame.
[0026] Furthermore, the first support frame has a first threaded hole that connects to the first insertion hole. Specifically, the first threaded hole is opened in the first vertical rod 211, and the first positioning pin 23 is threadedly connected to the first threaded hole. The circumferential sidewall of the first support rod 22 has a plurality of limiting grooves for cooperating with the inner end of the first positioning pin 23, and each limiting groove is arranged sequentially along the axial direction of the first support rod 22. When the first positioning pin 23 is turned in the forward direction, it moves towards the first support rod 22, and its inner end engages with one of the limiting grooves. This restricts the movement of the first support rod 22 within the first insertion hole, locking the relative position of the first support rod 22 and the first support frame. Correspondingly, the height of the first support foot 20 is also locked. When the first positioning pin 23 is turned in the reverse direction, it moves away from the first support rod 22, and its inner end separates from the limiting groove. This allows the first support rod 22 to move freely within the first insertion hole, and the position of the first support rod 22 and the first support frame can be adjusted arbitrarily. Correspondingly, the height of the first support foot 20 can also be adjusted arbitrarily. Of course, in other embodiments, the side wall of the first support rod 22 may not have a limiting groove; the friction between the inner end of the first positioning pin 23 and the side wall of the first support rod 22 will restrict its free movement within the first insertion hole. In another embodiment, the limiting groove can be replaced by a through hole in the first support rod 22.
[0027] Please combine Figure 3In this embodiment, the second support foot 30 includes a second support frame, a second support rod, and a second positioning pin. The second support frame has a second insertion hole, and the upper end of the second support rod has a transverse connecting rod 31. The connecting rod 31 is hinged to the side of the support plate. Specifically, the connecting rod 31 is hinged to the side of the support plate 10 so that the support plate 10 can rotate around the connecting rod 31. The lower end of the second support rod is movably inserted into the second insertion hole along its own axial direction. The second positioning pin penetrates the hole wall of the second insertion hole from the outer surface of the second support frame and can be detachably abutted against the second support rod. When the second positioning pin abuts against the second support rod, the relative position of the second support rod and the second support frame is defined by the second positioning pin. The second support frame has a second threaded hole communicating with the second insertion hole. The second positioning pin is threadedly connected to the second threaded hole. The circumferential side wall of the second support rod has multiple limiting grooves for cooperating with the inner end of the second positioning pin. The limiting grooves are arranged sequentially along the axial direction of the second support rod. The second support frame includes a second horizontal rod and a second vertical rod; the second vertical rod is connected to the second horizontal rod; a second insertion hole is opened inside the second vertical rod and extends along the axial direction of the second vertical rod.
[0028] In this embodiment, the structure of the second support leg 30 differs from that of the first support leg 20 in that the second support leg 30 does not have a second hinge plate 24, while the first support leg 20 has a second hinge half. Furthermore, the second support leg 30 has a connecting rod 31, while the first support leg 20 does not. Apart from these differences, the structure of the second support leg 30 is identical to that of the first support leg 20.
[0029] In this embodiment, the sliding assembly includes a sliding seat 41, a sliding member, and a third positioning pin 42. The sliding seat 41 is fixed to the first hinge plate 50 and has a sliding groove; the sliding member is fixed to the bearing plate 10 and slides in contact with the sliding groove; a third threaded hole is provided on the side wall of the sliding groove, and the third positioning pin 42 is threadedly engaged with the third threaded hole. When the third positioning pin 42 is turned in the forward direction, it moves toward the sliding member and abuts against the sliding member. The inner end of the third positioning pin 42 restricts the movement of the sliding member in the sliding groove, thereby limiting the relative position of the sliding member and the sliding seat 41, thus locking the distance between the first support foot 20 and the second support foot 30; when the third positioning pin 42 is turned in the reverse direction, it moves away from the sliding member, and the inner end of the third positioning pin 42 separates from the sliding member, so that the sliding member can move freely along the sliding groove to freely adjust the distance between the first support foot 20 and the second support foot 30. Of course, the sliding assembly can also be other structural components that allow the first hinge plate 50 to slide onto the support plate 10. For example, in other embodiments, if there are high requirements for the distance accuracy between the first support foot 20 and the second support foot 30, the sliding assembly can also be a linear module, a lead screw structure, an electric cylinder structure, etc., but this will increase the manufacturing cost.
[0030] Please continue reading Figure 1 and Figure 2 In this embodiment, the sliding seat 41 is a plate, and its bottom side is welded to the top surface of the first hinge plate 50. The sliding groove is a strip-shaped groove extending along the length of the sliding seat 41. The top side of the sliding seat 41 abuts against the bottom side of the support plate 10, and the sliding seat 41 serves to support the support plate 10. The sliding member is a rod parallel to the support plate 10. The upper side of the rod is welded to the bottom side of the support plate 10, and the lower side of the sliding member is located in the sliding groove and can move along the sliding groove. The side wall of the sliding member is also provided with multiple slots arranged sequentially along the length of the sliding member. The slots are used to cooperate with the inner end of the third positioning pin 42. When the inner end of the third positioning pin 42 cooperates with the slot, the third positioning pin 42 can restrict the sliding member from moving along the sliding groove. Of course, in other embodiments, the sliding member does not need to be provided with slots. The sliding member is limited by the friction between the inner end of the third positioning pin 42 and the side wall of the sliding member, so that the sliding member cannot move along the sliding groove. In another embodiment, the sliding member can be provided with through holes instead of slots.
[0031] The structure of the snap-fit assembly in this embodiment will be described next.
[0032] Please see Figure 4 In this embodiment, the first fastener 60 detachably connects the first transverse rod 212 of the first support leg 20 to the operating table 70, and the second fastener detachably connects the second transverse rod of the second support leg 30 to the operating table 70. Preferably, two first fasteners 60 are configured, using two first fasteners 60 to connect the two ends of the first transverse rod to the operating table 70 respectively. Similarly, two second fasteners are also configured. In this embodiment, the structure of the first fastener 60 is the same as the structure of the second fastener. Therefore, this embodiment only describes the structure of the first fastener 60, and the specific structure of the second fastener will not be described in detail. In other embodiments, the structure of the second fastener may be different from the structure of the first fastener 60.
[0033] In this embodiment, the first fastener 60 includes a left claw arm 61, a right claw arm 62, and a screw 63. The right claw arm 62 is rotatably connected to the unthreaded portion of the screw 63, and the left claw arm 61 is threadedly connected to the threaded portion of the screw 63. A locking space is formed between the left claw arm 61 and the right claw arm 62. One end of the screw 63 is provided with a handle. When the handle is turned, the handle drives the screw 63 to rotate, and the screw 63 rotates relative to the left claw arm 61. The left claw arm 61 moves along the axial direction of the screw 63. The driving principle is similar to that of a lead screw drive. Simultaneously, the right claw arm 62 also rotates relative to the screw 63. Since the part where the screw 63 and the right claw arm 62 engage is not threaded, the right claw arm 62 only rotates relative to the screw 63 and does not move along the axial direction of the screw 63. In practical applications, when the first support leg 20 needs to be connected to the operating table 70, firstly, the first transverse bar 212 and the side rail of the operating table 70 are brought into the engagement space. Then, the handle is rotated clockwise, causing the left claw arm 61 to move towards the right claw arm 62, thereby continuously reducing the engagement space. This engagement space connects the first transverse bar 212 to the side rail of the operating table 70, thus connecting the first support leg 20 to the operating table 70. When it is necessary to remove the first support leg 20 from the operating table 70, the handle is rotated counterclockwise, causing the left claw arm 61 to move away from the right claw arm 62, continuously expanding the engagement space. This separates the first transverse bar 212 from the side rail of the operating table 70, allowing the first support leg 20 to be removed from the operating table 70. Of course, this embodiment only illustrates one feasible structure of the first fastener 60. In other embodiments, the first fastener 60 can be other structures, as long as it can detachably fasten the first crossbar to the operating table 70.
[0034] Any combination of various embodiments of the present invention, provided it does not violate the inventive concept of the present invention, shall be regarded as the content disclosed by the present invention; within the scope of the technical concept of the present invention, any simple modifications to the technical solution and any combination of different embodiments that do not violate the inventive concept of the present invention shall be within the protection scope of the present invention.
