[0036] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0038] The operating table side rail fixing device will be described in detail below through specific embodiments:

[0039] Reference Figures 1 to 8As shown, some embodiments of this application provide an operating table side rail fixing device, including a fixing member 1, a sliding member 2, and a pressing member 3.

[0040] The fixing member 1 has a first limiting part 11 at one end along the first direction, which abuts against one side of the side rail along the first direction. The sliding member 2 has a second limiting part 21 at one end along the first direction, which abuts against one side of the side rail along the first direction. The pressing member 3 is located at the other end of the fixing member 1 along the first direction and is slidably connected to the fixing member 1 along the first direction. The pressing member 3 has a first abutting surface 31 and a second abutting surface 32, which abut against the other side of the side rail along the first direction. During the process of pushing the pressing member 3 to slide relative to the fixing member 1 along the first direction, the pressing member 3, the first limiting part 11, and the second limiting part 21 can be pressed against the two sides of the side rail along the first direction respectively.

[0041] The sliding member 2 is slidably connected to the fixed member 1 along the second direction, which intersects with the first direction. During the process of pushing the sliding member 2 relative to the fixed member 1 along the second direction, under the combined action of the first limiting part 11 and the second limiting part 21, the fixed member 1 and the sliding member 2 can wrap around the outside of the side rail and be fixed, resulting in high stability.

[0042] In practice, the first abutment surface 31 and the second abutment surface 32 are opposite each other along the second direction, and in the direction along the first direction toward the side rail, the first abutment surface 31 and the second abutment surface 32 are set away from each other. That is to say, the position of the pressure member 3 relative to the fixing member 1 along the first direction is adjustable, and the position of the sliding member 2 relative to the fixing member 1 along the second direction is adjustable. Side rails of different thicknesses can also abut against different positions of the first abutment surface 31 and the second abutment surface 32. In this way, it can be adapted to a variety of different specifications of operating table side rails, with high versatility. No extra tools are required during installation. The mechanical linkage between the fixing member 1, the sliding member 2 and the pressure member 3 can realize the function of quick clamping and adjustment, shortening the adjustment time during operation.

[0043] Specifically, the first direction can be the inner or outer direction of the side rail, and the second direction can be the upper or lower direction of the side rail.

[0044] In some embodiments, a guide rod 4 is provided on the slider 2, and a guide rod groove is provided on the fixing member 1 extending along the second direction. The guide rod 4 is inserted into the guide rod groove and slides in cooperation with the guide rod groove along the second direction. Specifically, after the guide rod 4 is inserted into the guide rod groove, under the restriction of the guide rod groove, the guide rod 4 and the slider 2 are only allowed to move linearly along the extension direction of the guide rod groove, which can avoid deflection or tilting, ensure the stability of the movement trajectory of the slider 2, avoid intraoperative displacement, and improve safety.

[0045] Reference Figure 4As shown, the outer wall of the guide rod 4 is provided with multiple limiting teeth 41, which are arranged sequentially along the second direction. A button 12 is provided on the fixing member 1, and the button 12 is provided with a mating tooth 121. The mating tooth 121 can be switched to engage with one of the limiting teeth 41 to fix the position of the sliding member 2 relative to the fixing member 1. Specifically, the outer wall of the guide rod 4 can be formed into a sawtooth structure. When the mating tooth 121 engages with the limiting teeth 41 at different positions, the button 12 can be locked at different heights on the guide rod 4, thereby adjusting the height of the sliding member 2 relative to the fixing member 1, thus enabling compatibility with different specifications of operating table side rails.

[0046] In practice, one of the walls of the limiting tooth 41 is set to extend horizontally, which can ensure the stability of the vertical limiting.

[0047] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5 As shown, the fixing member 1 is provided with a button groove 13, which is connected to the guide rod groove. The button 12 is inserted into the button groove 13 and slides with the button groove 13 to drive the mating teeth 121 to engage or disengage with the limiting teeth 41.

[0048] In other words, when the button 12 slides in the button groove 13, it can drive the mating tooth 121 to move closer to or further away from the guide rod 4 in the guide rod groove, thereby driving the mating tooth 121 to engage or disengage with the limiting tooth 41. Thus, when the mating tooth 121 engages with the limiting tooth 41, it can lock the sliding member 2. When the mating tooth 121 disengages with the limiting tooth 41, it can release the sliding member 2 to adjust the position of the sliding member 2 relative to the fixed member 1.

[0049] In specific implementation, refer to Figure 4 and Figure 5 As shown, the button 12 is provided with a relief groove 122, which extends along the sliding direction of the button 12. The guide rod 4 is inserted into the relief groove 122 and slides in cooperation with it. The mating teeth 121 are located on the inner wall of the relief groove 122. With this configuration, when the button groove 13 and the guide rod groove are connected, the button 12 can be slidably inserted into the button groove 13, and the guide rod 4 can be slidably inserted into the guide rod groove. There is no movement interference between the guide rod 4 and the button 12. The mating teeth 121 are located on the inner wall of the relief groove 122 and can mesh with the limiting teeth 41 on the guide rod 4, thereby achieving the limiting and fixing between the guide rod 4 and the button 12, and thus fixing the position of the sliding member 2 relative to the fixed member 1.

[0050] In some embodiments, refer to Figure 5As shown, there are two buttons 12 and two guide rods 4. The two guide rods 4 are inserted into the clearance slots 122 on the two buttons 12 in a one-to-one correspondence. An elastic member 14 is elastically supported between the two buttons 12. The two buttons 12 are located on both sides of the fixing member 1 along the third direction and can slide along the third direction. The third direction, the first direction, and the second direction are orthogonal to each other.

[0051] During installation, pressing the buttons 12 on both sides compresses the elastic element 14, disengaging the meshing teeth 121 and the limiting teeth 41. This allows the height of the sliding element 2 to be adjusted to fit the shape of the side rail. Once the sliding element 2 is in place, releasing the buttons 12 causes them to spring back, engaging the meshing teeth 121 and the limiting teeth 41 to lock the sliding element 2 at the current position of the limiting teeth 41 and fix it to the side rail, thus enabling installation.

[0052] In some embodiments, refer to Figure 2 As shown, the guide rod 4 is provided with a first limiting groove 42, and the fixing member 1 is provided with a first limiting member 15. The first limiting member 15 is inserted into the first limiting groove 42 and slides in cooperation with the first limiting groove 42 along the sliding direction of the guide rod 4. In specific implementation, by limiting the extension length of the first limiting groove 42, the movement range of the guide rod 4 can be limited, avoiding excessive stretching that could cause structural damage, and enabling precise control of the stroke of the guide rod 4.

[0053] The button 12 is provided with a second limiting groove 123, and the fixing member 1 is provided with a second limiting member 16. The second limiting member 16 is inserted into the second limiting groove 123 and slides with the second limiting groove 123 along the sliding direction of the button 12. Specifically, by limiting the extension length of the second limiting groove 123, the movement range of the button 12 can be limited, avoiding excessive stretching that could cause structural damage, and enabling precise control of the travel of the button 12.

[0054] In some embodiments, refer to Figure 1 and Figure 2 As shown, the pressure member 3 includes a pressure plate 33 and pressure rods 34 disposed on the pressure plate 33. The pressure rods 34 are slidably engaged with the fixing member 1 in a first direction. There are at least two pressure rods 34, and at least two pressure rods 34 are spaced apart in a second direction. The end face of one pressure rod 34 is formed as a first abutment surface 31, and the end face of the other pressure rod 34 is formed as a second abutment surface 32. That is, the pressure rods 34 can move in the first direction under the action of the pressure plate 33, and the first abutment surface 31 and the second abutment surface 32 can move toward the side rail to abut against the side rail.

[0055] Specifically, there are four pressure rods 34, which are arranged in pairs opposite each other along the second direction. All four pressure rods 34 can abut against the side rail, and the abutment force is evenly distributed, which can prevent the side rail from deforming and improve the installation stability.

[0056] In a specific implementation, the fixing member 1 is provided with a first through groove 17, and at least one pressure rod 34 passes through the first through groove 17 and slides in cooperation with the first through groove 17 in a first direction, so as to guide the pressure rod 34 to slide in the first direction through the first through groove 17; and / or, the sliding member 2 is provided with a second through groove 22, and at least one pressure rod 34 passes through the second through groove 22 and slides in cooperation with the second through groove 22 in a first direction, so as to guide the pressure rod 34 to slide in the first direction through the second through groove 22.

[0057] Reference Figure 2 As shown, the second through groove 22 has an avoidance opening on the side facing the fixing member 1 along the second direction. When the sliding member 2 slides along the second direction, the guide rod 4 is avoided through the avoidance opening, which can prevent the pressure rod 34 from interfering with the sliding member 2 and ensure smooth installation.

[0058] In some embodiments, a screw 35 is provided on the pressure plate 33, the screw 35 is threadedly engaged with the pressure plate 33, one end of the screw 35 passes through the pressure plate 33 and is rotatably connected to the fixing member 1, and the other end of the screw 35 is provided with a knob 36.

[0059] Understandably, at least two pressure rods 34 are inserted into the first through slot 17 and / or the second through slot 22 to prevent relative rotation of the pressure plate 33. This allows the pressure plate 33 to move along the first direction under the rotation of the screw 35, enabling the first abutment surface 31 and the second abutment surface 32 to abut against the side rail. Specifically, installation can be achieved by rotating the screw 35 using the knob 36.
