[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 3As shown, this utility model provides an operating table clamping mechanism 100, which is used to fix a surgical robot to an operating table. The operating table clamping mechanism 100 includes a track clamping assembly 1, a height coarse adjustment component, a pressing assembly, and a clamping assembly 2. The track clamping assembly 1 is installed on the guide rail on the side of the operating table. The clamping assembly 2 is connected to the track clamping assembly 1 through the height coarse adjustment component. The pressing assembly is located between the track clamping assembly 1 and the clamping assembly 2, and the pressing assembly is connected to the clamping assembly 2 through the height fine adjustment component. When the track clamping assembly 1 is installed on the guide rail on the side of the operating table, the pressing assembly can be pressed against the surface of the operating table through the height coarse adjustment component and the height fine adjustment component. Thus, by adjusting the height coarse adjustment component (first-level adjustment) and the height fine adjustment component (second-level adjustment), the distance between the clamping assembly and the operating table surface is adjusted. This allows the operating table clamping mechanism 100 to adapt to different operating table guide rails and surface heights. It also ensures that the clamping assembly can move slowly and smoothly press against the operating table surface, achieving the goal of having most of the weight of the operating table clamping mechanism 100 and its supporting surgical robot borne by the operating table surface, thereby guaranteeing the service life of the operating table side guide rails. Preferably, the height coarse adjustment component includes multiple shims 3 of the same and / or different heights, so that by selecting a single shim 3 or a combination of multiple shims 3 of appropriate height, the operating table clamping mechanism 100 can adapt to different specifications of operating tables. Of course, the height coarse adjustment component can also be other structural components with a certain load-bearing capacity and capable of adjusting the distance between the clamping assembly 2 and the track clamping assembly 1; this application does not limit this.

[0029] Specifically, such as Figures 1 to 3 As shown, the operating table clamping mechanism 100 is mounted on the guide rail on the side of the operating table via the track clamping assembly 1. A height-adjusting block 3 of appropriate height is connected between the track clamping assembly 1 and the clamping assembly 2 as a coarse height adjustment component to perform primary adjustment of the distance between the clamping assembly and the operating table surface. A secondary height adjustment is performed by adjusting the fine height adjustment component to move the clamping assembly away from the clamping assembly 2 and closer to the operating table surface, allowing the clamping assembly to slowly press against the operating table surface, thus locking the operating table clamping mechanism 100 to the operating table. The clamping assembly 2 carries a surgical robot used for performing surgery on the patient. The track clamping assembly 1 can slide along the axis of the guide rail on the side of the operating table to allow the operating table clamping mechanism 100 to be positioned at any position along the length of the operating table, facilitating flexible positioning of the surgical robot on the operating table.

[0030] According to a preferred embodiment of the present invention, the clamping assembly includes two sets of support roller modules 4, which are spaced apart and connected to the clamping assembly 2 along the length of the operating table. Specifically, as shown... Figure 1As shown, two sets of support roller modules 4 are symmetrically arranged at the bottom positions near both ends of the clamping assembly 2, and the support roller modules 4 are located on the side of the clamping assembly 2 closest to the operating table. This allows the force on the clamping assembly 2 to be transmitted more evenly to the operating table, while also providing more stable support for the surgical robot.

[0031] According to one embodiment of the present invention, such as Figure 2 As shown, the support roller module 4 includes a roller 41 and a roller support base 42 connected to each other. The support roller module 4 is connected to the clamping assembly 2 through the roller support base 42. When the track clamping assembly 1 is installed on the guide rail on the side of the operating table, the roller 41 can be pressed against the surface of the operating table. Specifically, a height adjustment component is connected between the clamping assembly 2 and the roller support base 42. By adjusting the height adjustment component, the roller support base 42 can drive the roller 41 to move closer to the surface of the operating table, so that the roller 41 slowly contacts and presses against the surface of the operating table. Preferably, to avoid scratching the operating table surface during the contact between the roller 41 and the operating table surface, the roller 41 is made of nylon.

[0032] According to a preferred embodiment of the present invention, the height adjustment component includes a set screw and a connecting screw. The set screw is threadedly connected to the clamping assembly 2 and abuts against the set screw top surface 421 of the clamping assembly. The connecting screw passes through the clamping assembly 2 and is threadedly connected to the clamping assembly. Specifically, as shown... Figure 2 As shown, the top surface of the roller support 42 forms a set screw top surface 421. The roller support 42 is provided with a threaded deep hole 422 that mates with the connecting screw. The support roller module 4 is detachably connected to the clamping assembly 2 through the set screw and the connecting screw. The distance between the clamping assembly and the operating table surface can be adjusted in two stages by adjusting the engagement length of the set screw and the connecting screw.

[0033] According to a preferred embodiment of the present invention, the clamping assembly 2 includes a support plate 21, an optical axis seat 22, and an optical axis 23. The support plate 21 is fixedly connected to the track clamping assembly 1 via a shim 3. A pressing assembly is connected to the support plate 21. When the track clamping assembly 1 is installed on the guide rail on the side of the operating table, the support plate 21 is located above the operating table. Along the length of the operating table, the optical axis seat 22 is symmetrically connected to both sides of the support plate 21, and the optical axis 23 is installed on the optical axis seat 22. Specifically, as shown... Figure 1 and Figure 2As shown, the support plate 21 is rectangular. Optical shafts 23 are symmetrically connected to the two sides of the support plate 21, which are positioned opposite each other along the length of the operating table, via optical shaft seats 22, to facilitate docking with the transport trolley and enable rapid transport of the surgical robot on the trolley. The support plate 21 has threaded holes 211 for set screws and countersunk holes 212 for connecting screws to connect the support roller module 4. The support plate 21 is fixedly connected to the track clamping assembly 1 via screws passing through the shim block 3.

[0034] According to a preferred embodiment of the present invention, the optical axis 23 has an extension extending out of the operating table, the extension for supporting the surgical robot in operation. By providing the extension, the surgical robot is positioned outside the operating table surface after assembly and operation, so as not to affect the patient's lying space.

[0035] According to a preferred embodiment of this utility model, there are two track clamping components 1, which are symmetrically installed on the guide rails on both sides of the operating table. Thus, operating table clamping mechanisms 100 are installed on both sides of the operating table, providing interfaces on both sides of the operating table for connecting to the storage interface of the transfer trolley. This allows the surgical robot to be installed from any position on either side of the operating table, avoiding installation difficulties caused by the spatial layout of the operating room.

[0036] According to a preferred embodiment of the present invention, such as Figure 1 As shown, the clamping assembly 2 includes a first support plate, a second support plate, an optical axis 23, and an optical axis seat 22. The first and second support plates are symmetrically connected to two track clamping assemblies 1 via height adjustment components. Both the first and second support plates are connected to clamping components. When the track clamping assembly 1 is installed on the guide rails on the side of the operating table, the first and second support plates are positioned above the operating table. Along the length of the operating table, optical axis seats 22 are symmetrically connected to both sides of the first and second support plates, and an optical axis 23 is connected to the optical axis seat 22 on the same side. The components connected to both sides of the operating table are connected into a single unit via the optical axis 23, facilitating the assembly and disassembly of the operating table clamping mechanism 100 along the guide rails on the side of the operating table, thus enabling rapid installation of the operating table clamping mechanism 100.

[0037] According to a preferred embodiment of the present invention, the optical axis 23 has a through section spanning the operating table and an extension section extending out of the operating table, the extension section being used to support the surgical robot in operation. In this way, both the integrated assembly of the operating table clamping mechanism 100 and the preservation of the patient's lying space from encroachment by the surgical robot are achieved.

[0038] According to a preferred embodiment of the present invention, such as Figure 2As shown, the optical axis 23 has a first end and a second end opposite to each other. A fixed mounting hole 231 is provided near the first end, and a plurality of adjustable mounting holes 232 are provided near the second end. The plurality of adjustable mounting holes 232 are spaced apart along the axial direction of the optical axis 23. By providing the fixed mounting hole 231 and the adjustable mounting holes 232, the operating table clamping mechanism 100 can be adapted to operating tables of different sizes.

[0039] Based on the above description, the operating table clamping mechanism 100 provided in this embodiment of the present invention has the following beneficial effects:

[0040] The operating table clamping mechanism 100 provided in this embodiment of the invention achieves distance adjustment between the clamping component and the operating table surface through a primary adjustment of the coarse height adjustment component and a secondary adjustment of the fine height adjustment component. This allows the operating table clamping mechanism 100 to adapt to different operating table guide rails and surface heights, and enables the clamping component to move slowly and smoothly press against the operating table surface. This ensures that most of the weight of the operating table clamping mechanism 100 and the surgical robot it carries is borne by the operating table surface, thereby guaranteeing the service life of the operating table side guide rails. Furthermore, the clamping component 2 enables rapid transfer of the surgical robot through quick docking with the transport trolley. Simultaneously, by setting up shims 3 of different heights, it can adapt to different operating table specifications, thus broadening its applicability. In addition, through the improved configuration of the operating table clamping mechanism 100, both sides of the operating table have interfaces for docking with the storage interface of the transport trolley, allowing the surgical robot to be installed from any position on either side of the operating table, avoiding installation difficulties caused by operating room space layout issues.

[0041] The above descriptions are merely a few embodiments of this utility model. Those skilled in the art can make various modifications or variations to the embodiments of this utility model based on the content disclosed in the application documents without departing from the spirit and scope of this utility model.
