Description

Technical Field

[0001] This utility model relates to auxiliary devices for conventional operating tables, specifically to an upper limb operating table used in combination with an operating table. Background Technology

[0002] For patients undergoing upper limb surgery, whether it's hand trauma, fixation of nerves, blood vessels, or fractures in the forearm or upper arm, or tumor resection and reconstruction, the patient's upper limb needs to be placed on an operating table outside the operating bed for easier operation. The surgeon also needs to sit beside the patient's upper limb during the procedure. Currently, existing operating tables do not have dedicated upper limb operating tables; therefore, simple square operating tables made of stainless steel have been used for upper limb surgery. These four-legged operating tables are not only bulky and difficult to move, but also hinder the use of C-arm machines during surgery.

[0003] Improvements have been made in the prior art, such as the detachable upper limb operating table with authorization announcement number CN208756417U, which includes a table surface and a clamping device installed on the back of the table surface. The clamping device includes a fixed clamping claw and a flexible clamping claw. The claw heads of the fixed clamping claw and the claw heads of the flexible clamping claw cooperate with each other to form a clamping structure on the support rod of the operating table edge, thereby clamping the table surface onto the operating table for upper limb surgery.

[0004] However, the detachable upper limb operating table disclosed in the aforementioned patent documents, as indicated in the instruction manual... Figure 1 It can be seen that the table adopts a cantilever beam structure, and the connecting parts adopt an unstable elastic structure, which is prone to shaking during upper limb surgery and affects the surgical results.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0028] To address the drawback of existing operating tables where the table surface is prone to wobbling, the inventors, after careful analysis, discovered that the main reason for this technical problem lies in the fact that existing detachable upper limb operating tables use a clamping structure formed by the interaction of fixed and elastic claws to hold the table surface against the support rods along the edge of the operating table for upper limb surgery. While this connection structure does not interfere with the use of the C-arm machine during surgery, it creates a cantilever beam structure, resulting in unstable support for the upper limb operating table. Furthermore, the unstable elastic structure of the clamping mechanism easily causes wobbling during upper limb surgery, affecting the surgical outcome. Based on this analysis, the inventors designed an upper limb operating table that is used in conjunction with an operating table, featuring a "C"-shaped structure that does not interfere with the use of the C-arm machine during surgery. Simultaneously, a support frame is incorporated to support the table surface, combined with a clamping plate and slot, and a fastening mechanism, fixing the support table to the operating table in a way that prevents tilting and wobbling.

[0029] Example 1:

[0030] like Figures 1 to 2 As shown, the upper limb operating table used in combination with the operating table in this embodiment includes an operating table 1 and a support table 2 for supporting the upper limb. The operating table 1 is provided with a slot 11, and the support table 2 is provided with a plate 21, which can be inserted into the slot 11.

[0031] The support platform 2 includes a platform 22 and a bracket 23 located at its bottom, with casters 24 at the bottom of the bracket 23.

[0032] The support 23 and the table 22 are connected to form an approximately "C"-shaped structure, which defines a space for convenient movement of the C-arm machine. The support table 2 is also provided with a fastening mechanism 3, which includes a first screw 31, a pressure plate 32 and an operating handle 33. The support table 2 is provided with a threaded hole that mates with the first screw 31. The first screw 31 passes through the threaded hole, with one end connected to the pressure plate 32 and the other end fixedly connected to the operating handle 33. By rotating the operating handle 33, the first screw 31 can move axially, driving the pressure plate 32 to press or loosen the edge of the operating table 1, thereby fixing the support table 2.

[0033] The clamping plate 21 includes a connecting portion 25 and an insertion portion 26 formed by bending downward from the connecting portion 25. The connecting portion 25 is fixedly connected to the table surface 22, and the insertion portion 26 can be inserted into the clamping slot 11. When the insertion portion 26 is inserted into the clamping slot 11, it works in conjunction with the pressure plate 32 to press against the edge of the operating table 1, similar to how the insertion portion 26 and the pressure plate 32 work together to clamp the operating table 1, thus fixing the support table 2. The fastening mechanism 3 uses a threaded structure to press against the edge of the operating table 1, which is more stable than the elastic structure of the prior art and is less prone to shaking.

[0034] The pressure plate 32 is covered with a layer of anti-slip rubber pad. This increases friction and makes the support platform 2 more stable.

[0035] Example 2:

[0036] like Figures 3 to 6 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the support 23. The support 23 includes a base 231 and a height adjustment rod 232. The top of the height adjustment rod 232 is connected to one side of the tabletop 22, used to support and adjust the height of the tabletop 22. The bottom of the height adjustment rod 232 is connected to the base 231, and casters 24 are located at the bottom of the base 231. The adjustable height of the tabletop 22 ensures that the base 231 can contact the ground, preventing the support table 2 from easily wobbling. The support 23 supports the tabletop 22, reducing the stress on the clamping plate 21 and improving the service life of the upper limb operating table.

[0037] The height adjustment lever 232 includes an upper lever 7, a lower lever 8, and a lifting assembly 9. One end of the lower lever 8 is connected to the base 231, and the other end is connected to the upper lever 7. The upper lever 7 is fitted inside the lower lever 8 and slides through the lifting assembly 9. The upper lever 7 is connected to the platform 22. The lifting assembly 9 includes a driving gear, a driven gear, and a handle for driving the driving gear. The upper lever 7 is threadedly connected to the lower lever 8. The driven gear is fitted onto the upper lever 7 and fixedly connected to it. The driving gear meshes with the driven gear. The upper lever 7 includes a housing and a screw. One end of the screw is rotatably mounted inside the housing. The driven gear is fitted onto the screw and fixedly connected to it. The other end of the screw is threadedly connected to the lower lever 8. Both the driving gear and the driven gear are bevel gears.

[0038] The base 231 is I-shaped and includes a telescopic rod 233, a horizontal rod 234, and a vertical rod 235. The two ends of the horizontal rod 234 are fixedly connected to the telescopic rod 233 and the vertical rod 235, respectively. A height adjustment rod 232 is connected to the horizontal rod 234. The telescopic rod 233 includes an inner rod 236 and an outer rod 237 that are sleeved together, and a locking knob 238 for locking the relative positions of the inner rod 236 and the outer rod 237. The outer rod 237 has a through-groove on one side and a guide rail on the other side. The inner rod 236 has a slide bar 4 on one side, which is slidably embedded in the groove. The side of the slide bar 4 is flush with the side of the outer rod 237. The locking knob 238 is connected to the inner rod 236 on one side and extends out of the outer rod 237 from the guide rail on the other side. The locking knob 238 includes a second screw 230 and a wing nut 239 that matches the second screw 230. One end of the second screw 230 is fixedly connected to the inner rod 236, and the other end passes through the guide rail and is fitted with the wing nut 239. The wing nut 239 is blocked outside the outer rod 237. The base 231 is provided with a telescopic rod 233 to ensure that one side of the base 231 can support the operating table 1, and the upper limb operating table is not easy to tilt.

[0039] A step 5 is formed at the connection between the slide bar 4 and the inner rod 236, and the step 5 is blocked inside the outer rod 237. The step 5 and the locking knob 238 work together to prevent the slide bar 4 from tilting, so that the slide bar 4 can slide smoothly along the guide rail, ensuring that one side of the base 231 supports the area of ​​the operating table 1, and enhancing the stability of the upper limb operating table.

[0040] Example 3:

[0041] like Figures 7 to 8 As shown, the difference between Embodiment 3 and Embodiment 1 is that the table surface 22, on the side away from the clamping plate 21, is provided with a snap-fit ​​assembly 6. The snap-fit ​​assembly 6 is used to detachably fix the support table 2 to the bed board of the operating table 1. The snap-fit ​​assembly 6 is U-shaped and includes a connecting plate, first clamping arms disposed on both sides of the connecting plate, and a fixing plate. A second clamping arm is movably disposed between the first clamping arm and the fixing plate. After the second clamping arm moves, the first clamping arm and the second clamping arm cooperate to clamp the bed board of the operating table 1. By using the snap-fit ​​assembly 6, the upper limb operating table is fixed to the foot of the operating table 1, which can increase the length of the operating table 1.

[0042] All the above embodiments are exemplary and not restrictive. Any modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
