Description

Technical Field

[0001] This utility model relates to the field of medical bed technology, specifically to a dual-purpose operating bed extension plate and a novel operating bed. Background Technology

[0002] During medical surgeries, the versatility and ease of use of the operating table significantly impact the efficiency of medical staff and the patient's surgical experience. Traditional operating table components (such as leg panels) are often made of ordinary steel, making them heavy and cumbersome for medical staff during installation, disassembly, and transport, especially during emergency surgeries or frequent repositioning, which can increase their workload. Furthermore, during surgery, depending on the patient's body size and the type of surgery, it is often necessary to widen or lengthen the operating table to meet surgical needs; however, existing leg panels can only accommodate lengthening, not width expansion.

[0003] A search revealed that while some solutions have been found in existing patents, they still suffer from the drawback of limited functionality. They only extend the tail or widen the sides, lacking integrated functionality and failing to coordinate with the operating table from multiple angles, thus reducing the performance of the operating table. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes a dual-purpose operating table extension plate and a novel operating table.

[0005] The technical solution to the technical problem solved by this utility model is as follows: Firstly, this technical solution proposes a dual-purpose operating table extension plate, comprising: Support layer; one end of the support layer is fixedly connected to a plug-in post and a positioning pin as an extension connection point; the plug-in post is provided with a positioning ring groove; A cushion layer is placed above the support layer, with the bottom of the cushion layer connected to the top of the support layer; At least one snap-fit ​​unit, which serves as an extended connection point, is rotatably connected to the bottom of the support layer; The length direction of the support layer is defined as the first direction, and the width is defined as the second direction; the snap-fit ​​unit can rotate relative to the support layer and can be positioned and locked in the first and second directions respectively after rotation.

[0006] Preferably, one end of the support layer is fixedly connected to a boss, and one end of the insertion post and the positioning pin is fixedly connected to the boss.

[0007] Preferably, the support layer is made of carbon fiber composite material, aluminum alloy, or magnesium alloy.

[0008] Preferably, the buckle unit includes a base fixedly connected to the bottom of the support layer, the base having a central hole in the middle, and a locking hole on the side wall of the base, where a locking rod is threadedly connected; a main shaft is rotatably connected to the bottom of the base, and the main shaft has limiting grooves along a first direction and a second direction respectively for use with the locking rod, so that when the locking rod is screwed on, one end of the locking rod can be inserted into the limiting groove for limiting; the bottom end of the main shaft is fixedly connected to a card holder, and the card holder has a bayonet.

[0009] Preferably, the bayonet has an "n" shaped structure.

[0010] Preferably, the card holder includes a horizontal plate, one end of which is bent downward to form an upper card platform; a vertical plate is fixedly connected to the bottom of the horizontal plate, and a lower card platform is connected to the bottom of the vertical plate via a pivot. The lower card platform can rotate relative to the vertical plate, and a handle is connected to one end of the lower card platform; the lower card platform and the upper card platform cooperate to form the card slot; a torsion spring is sleeved on the pivot, one end of which is connected to the vertical plate, and the other end of which is connected to the lower card platform.

[0011] Preferably, the vertical plate is threaded with a set screw.

[0012] Secondly, this technical solution also proposes a new type of operating table, including a base and a bed body located on top of the base. A bed surface is provided above the bed body, and guide rails are connected to the sides of the bed body. A dual-purpose operating table extension plate structure is detachably connected to the rear of the bed body and / or the guide rails.

[0013] Preferably, the rear of the bed has a mounting base, which has a plug-in hole and a positioning hole, and the plug-in hole and the positioning hole are respectively adapted to the plug-in post and the positioning pin for plug-in; the mounting base is threadedly connected to a threaded rod, and when the plug-in post is inserted into the plug-in hole, one end of the threaded rod can be adapted to and engaged with the positioning ring groove.

[0018] 4. The buckle unit has a rotating and retractable function. When the extension plate is used as a leg board, the buckle unit can be screwed into the support layer for storage, avoiding the unused buckle unit from being exposed and forming a protruding obstacle, reducing the risk of bumps and knocks for medical staff during operation, and preventing discomfort or injury caused by accidental contact between the patient's limbs and the buckle. When switching to the side to achieve the widening function, the buckle unit can be quickly rotated and unfolded, precisely docking with the bed rails. There is no need to disassemble or replace parts; the function can be switched by simply rotating, avoiding cumbersome procedures. Attached Figure Description

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figure 1 - Figure 8 As shown, this embodiment proposes a dual-purpose operating table extension plate, which mainly includes a support layer 1, a padding layer 2, and at least one snap-fit ​​unit 8, etc., which are described in detail below: One end of the support layer 1 is fixedly connected to a plug-in post 5 and a positioning pin 7, which serve as an extension connection point during use. The plug-in post 5 has a positioning ring groove 6, used for positioning and preventing detachment during use. In this embodiment, the support layer 1 can be made of lightweight, high-strength materials such as carbon fiber composite material, aluminum alloy, or magnesium alloy, effectively solving the technical problem of bulky traditional operating table accessories, making operation easier for medical staff, reducing labor intensity, and especially suitable for the high-frequency accessory adjustment needs of the operating room.

[0031] The padding layer 2 is located above the support layer 1, and the bottom of the padding layer 2 is connected to the top of the support layer 1. The core function of the padding layer 2 is to buffer pressure and improve the patient's lying comfort. At the same time, it must have a certain degree of shape stability. In this embodiment, the padding layer 2 can be made of high-density polyurethane foam, silicone foam, memory foam, sponge, etc. A leather sleeve can also be set on the outside of the padding layer 2. The leather sleeve can be made of medical PVC leather sleeve, TPU leather sleeve, etc.

[0032] The snap-fit ​​unit 8, as an extended connection point, is rotatably connected to the bottom of the support layer 1; the length direction of the support layer 1 is defined as the first direction and the width as the second direction; the snap-fit ​​unit 8 can rotate relative to the support layer 1 and can be positioned and locked in the first and second directions respectively after rotation.

[0033] The dual-purpose extension plate structure of the operating table breaks through the limitations of traditional extension components that can only be lengthened or widened in a single way. Through the integrated design of lengthening and widening connection points, a single extension plate can be connected to the foot of the bed to lengthen the operating table, and also connected to the side guide rail 12 to widen it, meeting the diverse scenarios of different patient body shapes and surgical types.

[0034] In some embodiments, for ease of installation, a boss 4 is fixedly connected to one end of the support layer 1, and one end of the plug post 5 and the positioning pin 7 is fixedly connected to the boss 4.

[0035] In some embodiments, the bottom surface of the support layer 1 is further provided with a reinforcing layer 3. This reinforcing layer 3 can be configured with a mesh-like structure, where the intersecting ribs form a network that effectively disperses the pressure on the support layer 1. Without significantly increasing the overall thickness of the support layer 1, it greatly improves its resistance to bending and deformation, ensuring that the extension plate remains structurally stable even under heavy loads when used as a leg plate or widening plate, preventing breakage or warping due to excessive stress. Compared to using solid sheet metal to increase strength, the mesh-like structure replaces "overall thickening" with "skeleton support," significantly reducing the material usage of the support layer 1 while maintaining strength, thereby reducing the overall weight of the extension plate. This advantage not only facilitates the handling, installation, and adjustment of the extension plate by medical personnel but also reduces the overall load on the operating table, extending the equipment's lifespan.

[0036] In some embodiments, the snap-fit ​​unit 8 includes a base 81 fixedly connected to the bottom of the support layer 1. The base 81 has a central hole 811 in the middle and a locking hole 812 on the side wall of the base 81. A locking rod 82 is threadedly connected to the locking hole 812. A main shaft 83 is rotatably connected to the bottom of the base 81. The main shaft 83 and the base 81 can be connected by a bearing. The main shaft 83 has limiting grooves 831 along the first direction and the second direction, which are used to cooperate with the locking rod 82. When the locking rod 82 is screwed, one end of the locking rod 82 can be inserted into the limiting groove 831 for limiting. By using the two limiting grooves 831, locking and fixing in two directions can be achieved, ensuring the reliability of the connection. When used as a leg plate, the locking rod 82 is embedded in the limiting groove 831 in the first direction to prevent the buckle unit 8 from accidentally rotating out; when used as a widening plate, the locking rod 82 is embedded in the limiting groove 831 in the second direction to ensure the perpendicularity and stability of the connection between the buckle and the guide rail 12, and to avoid angular displacement caused by the patient's weight or intraoperative vibration.

[0037] This locking structure is the core guarantee for the switching between the two states of the buckle unit 8: when hidden, the first direction locking ensures that the buckle fits snugly against the bottom of the support layer 1 without taking up extra space; when unfolded, the second direction locking ensures precise docking with the guide rail 12. The switching between the two states does not require disassembling any parts, thus achieving multi-functional integration.

[0038] The bottom end of the spindle 83 is fixedly connected to the mounting bracket, which has a bayonet. In some embodiments, the bayonet can be an "n"-shaped structure. The open end of the "n"-shaped structure has an open design, allowing medical personnel to directly align the bayonet with the guide rail 12 of the bed 11 in the vertical direction, making operation convenient.

[0039] Because the "n"-shaped structure is open, although convenient to operate, the lack of restraint at the bottom may make it prone to wobbling. Therefore, in some embodiments, the card holder can also adopt the following structure: The card holder includes a horizontal plate 84, one end of which is bent downwards to form an upper card platform 841. A vertical plate 85 is fixedly connected to the bottom of the horizontal plate 84, and a lower card platform 86 is connected to the bottom of the vertical plate 85 via a pivot. The lower card platform 86 can rotate relative to the vertical plate 85. The lower card platform 86 is integrally fixedly connected to the pivot, and both ends of the pivot are rotatably connected to the vertical plate 85. A handle 862 is connected to one end of the lower card platform 86, and the other end is bent upwards to form a folded edge 861. The lower card platform 86 and the upper card platform 841 cooperate to form the aforementioned card slot. A torsion spring 88 is sleeved on the pivot, one end of which is connected to the vertical plate 85, and the other end is connected to the lower card platform 86. The upper card platform 841 and the rotatable lower card platform 86 form a closed card slot that "wraps" the upper and lower parts, resulting in higher carding stability. One end of the lower card holder 86 is connected to the handle 862. Medical staff only need to pull the handle 862 downward to overcome the spring force of the torsion spring 88 and make the lower card holder 86 rotate downward (open the slot). After inserting into the guide rail 12, the handle 862 is released, and the lower card holder 86 automatically springs back and locks, making the operation convenient and efficient.

[0040] Due to machining errors, assembly errors, and wear and aging, the bayonet and guide rail 12 cannot achieve an ideal engagement. When gaps exist, the extension plate will tilt due to gravity, causing its surface to not remain flush with the bed surface 10, reducing comfort when lying down. For this reason, in some embodiments, a set screw 87 is threaded onto the vertical plate 85. The set screw 87 is threaded onto the vertical plate 85, and its end can directly push against the guide rail 12 when screwed, providing rigid support, preventing the extension plate from tilting, and ensuring that the surface of the padding layer 2 is flush with the bed surface 10.

[0041] This embodiment also proposes a novel operating table, including a base 9 and a bed body 11 located on top of the base 9. A bed surface 10 is provided above the bed body 11, and a guide rail 12 is connected to the side of the bed body 11. A dual-purpose operating table extension plate structure is detachably connected to the tail of the bed body 11 and / or the guide rail 12.

[0042] The bed frame 11 has a mounting base 13 at its tail end. The mounting base 13 has a plug-in hole 14 and a positioning hole 15, which are respectively matched and plugged into the plug-in post 5 and the positioning pin 7. The mounting base 13 is threadedly connected to a threaded rod 16. When the plug-in post 5 is inserted into the plug-in hole 14, one end of the threaded rod 16 can be matched and engaged with the positioning ring groove 6. The extended connection adopts the structure of plug-in post 5, positioning pin 7, and positioning ring groove 6 to ensure that the extension plate and the bed tail mounting base 13 are accurately connected and locked firmly to avoid shaking. This design not only ensures the accuracy and firmness of the connection, but also takes into account the convenience of operation and adaptability to different scenarios.

[0043] The snap-fit ​​unit 8 can be fitted and snapped into the guide rail 12. The guide rail is surrounded and engaged by the upper snap-fit ​​platform 841 and the lower snap-fit ​​platform 86, achieving a stable connection. The connection is extended by fitting and snapping the snap-fit ​​unit 8 into the guide rail 12 of the bed 11, which is labor-saving and reliable.

[0044] It should be noted that the buckle unit 8 has a rotating and hiding function. When the extension plate is used as a leg board, the buckle unit 8 can be screwed into the support layer 1 for storage, avoiding the unused buckle unit 8 from being exposed and forming a protruding obstacle, reducing the risk of bumps and knocks for medical staff during operation, and preventing discomfort or injury caused by accidental contact between the patient's limbs and the buckle. When switching to the side to achieve the widening function, the buckle unit 8 can be quickly rotated and unfolded, precisely docking with the guide rail 12 of the bed frame 11. There is no need to disassemble or replace parts. The function can be switched by rotation, avoiding cumbersome procedures.

[0045] Technical effects: This solution simplifies the structure while ensuring the connection strength in both modes, truly realizing the integrated value of "one board for two uses" and improving the overall utilization efficiency of operating table accessories.
