[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] like Figures 1 to 7 As shown, a connecting device includes a first electrical connector 3 and a second electrical connector 4. The connecting device is used to connect a support frame 1 at the end of a robotic arm and a connector 21 at the end of a surgical instrument 2. Data signals are transmitted between the support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2 via a connecting line. The first electrical connector 3 is disposed on the support frame 1 at the end of the robotic arm and has an end of a connecting line. The second electrical connector 4 is disposed on the connector 21 at the end of the surgical instrument 2 and has a conductive structure 24. The first electrical connector 3 and the second electrical connector 4 are detachably connected. When the first electrical connector 3 and the second electrical connector 4 are electrically connected, the conductive structure 24 is conductive to the end of the connecting line. When the first electrical connector 3 and the second electrical connector 4 are disassembled, the end of the connecting line is separated from the connector 21 at the end of the surgical instrument 2.

[0044] Specifically, by configuring the conductive structure 24 on the second electrical connector 4 of the connector 21 at the end of the surgical instrument 2, and configuring the end of the connecting wire on the first electrical connector 3 of the support frame 1 at the end of the robotic arm, the connector 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm can be modularized. By directly disassembling the modular connector 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm, the end of the connecting wire can be separated from the connector 21 at the end of the surgical instrument 2, improving the maintenance efficiency of the connector 21 at the end of the surgical instrument 2 and avoiding the problem of the connecting wire being suspended. By directly installing the modular connector 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm through the first electrical connector 3 and the second electrical connector 4, the electrical connection between the support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2 can be achieved, ensuring assembly efficiency and product safety.

[0045] The data information of the connector 21 at the end of the surgical instrument 2 is connected to the support frame 1 at the end of the robotic arm via a connecting cable. When the connector 21 at the end of the surgical instrument 2 malfunctions and needs maintenance, it needs to be removed from the support frame 1 at the end of the robotic arm. At this time, the connecting cable is suspended during the maintenance of the connector 21 at the end of the surgical instrument 2, which is prone to breakage and poses a safety hazard to the system. The first electrical connector 3 provided on the support frame 1 at the end of the robotic arm and the second electrical connector 4 provided on the connector 21 at the end of the surgical instrument 2 can be detachably connected. The first electrical connector 3 is equipped with the end of the connecting cable, thus achieving... In actual operation, the support frame 1, the first electrical connector 3, and the end of the connecting line at the end of the robotic arm are integrated components, as are the connector 21, the second electrical connector 4, and the end of the conductive structure 24 at the end of the surgical instrument 2. When it is necessary to inspect the connector 21 at the end of the surgical instrument 2, it is only necessary to disconnect the connection between the first electrical connector 3 and the second electrical connector 4, so as to conveniently and safely inspect the connector 21 at the end of the surgical instrument 2. When assembling the whole system, it is only necessary to install the modular support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2, which is efficient and more reliable.

[0046] The surgical instrument 2 includes a connecting seat 21 and an instrument body; the connecting seat 21 at the end of the surgical instrument 2 is connected to the support frame 1 at the end of the robotic arm, so the second electrical connector 4 is preferably disposed on the connecting seat 21.

[0047] The first electrical connector 3 and the second electrical connector 4 are detachably connected to achieve the connection between the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2. This avoids the need to connect the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2 by drilling or other means, making the connection operation simpler and more convenient and improving assembly efficiency.

[0048] The first electrical connector 3 and the second electrical connector 4 are preferably equipped with locking buckles at their detachable connection positions. That is, after the first electrical connector 3 and the second electrical connector are connected, they are locked by locking buckles to ensure the stability of the connection between the first electrical connector 3 and the second electrical connector 4. When the first electrical connector 3 and the second electrical connector 4 are to be disassembled, the locking buckles can be unlocked first.

[0049] For example, the first electrical connector 3 is a plug or a socket; the second electrical connector 4 is a socket or a plug.

[0050] Specifically, by selecting the first electrical connector 3 and the second electrical connector 4 as plug-in connection methods, the operation is simple and convenient, and the electrical connection relationship is stable and reliable.

[0051] In the first scheme, when the first electrical connector 3 is a plug, the second electrical connector 4 is a socket. When the connector 21 at the end of the surgical instrument 2 needs to be disassembled for maintenance, the modular integrated connector 21 and socket at the end of the surgical instrument 2 can be pulled out from the plug at the end of the robotic arm, which is simple and convenient. When it is necessary to install the connector 21 at the end of the surgical instrument 2 with the support frame 1 at the end of the robotic arm, the socket and plug can be plugged in.

[0052] In the second scheme, when the first electrical connector 3 is a socket, the second electrical connector 4 is a plug; when the connector 21 at the end of the surgical instrument 2 needs to be disassembled for maintenance, the modular integrated connector 21 and plug at the end of the surgical instrument 2 can be pulled out from the socket at the end of the robotic arm, making the operation simpler and more convenient; when it is necessary to install the connector 21 at the end of the surgical instrument 2 with the support frame 1 at the end of the robotic arm, the plug and socket can be plugged in.

[0053] Among them, when the first electrical connector 3 and the second electrical connector 4 are plugged in, a locking buckle can be provided on the side of the plugging position to ensure that the connection between the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2 is more secure and reliable.

[0054] For example, the support frame 1 at the end of the robotic arm is provided with a first guide structure 11; the connecting seat 21 at the end of the surgical instrument 2 is provided with a second guide structure 22 corresponding to the position of the first guide structure 11; the first guide structure 11 and the second guide structure 22 are connected to each other so that the support frame 1 at the end of the robotic arm is connected to the connecting seat 21 at the end of the surgical instrument 2.

[0055] Specifically, when assembling the connecting seat 21 at the end of the surgical instrument 2 with the support frame 1 at the end of the robotic arm, the first guide structure 11 is provided on the support frame 1 at the end of the robotic arm, and the second guide structure 22 is provided on the connecting seat 21 at the end of the surgical instrument 2 relative to the position of the first guide structure 11. This ensures a reliable and stable connection between the connecting seat 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm, ensuring more precise connection operations and avoiding misalignment or connection failure.

[0056] The first guide structure 11 and the second guide structure 22 can be multiple sets of mutually cooperating guide structures to ensure the stability and reliability of the connection between the connecting seat 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm during assembly.

[0057] For example, the first guide structure 11 includes a guide post or a guide hole; the second guide structure 22 includes a guide hole or a guide post.

[0058] Specifically, by providing guide posts and guide holes to the connecting seat 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm, a guiding structure is achieved between the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2 during the installation process. The structure is simple, ensures precise docking, and reduces production costs.

[0059] Preferably, guide posts and guide holes are respectively provided at two opposite positions of the connector 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm, to ensure that the multi-position guides are automatically aligned during connection and to avoid misalignment or connection failure.

[0060] For example, the support frame 1 at the end of the robotic arm is provided with a first limiting structure 12; the connecting seat 21 at the end of the surgical instrument 2 is provided with a second limiting structure 23 corresponding to the position of the first limiting structure 12; the first limiting structure 12 and the second limiting structure 23 cooperate to connect the support frame 1 at the end of the robotic arm to the connecting seat 21 at the end of the surgical instrument 2.

[0061] Specifically, by setting a first limiting structure 12 and a second limiting structure 23 at the corresponding positions of the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2, the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2 are connected in place when they are assembled, so as to ensure the reliability and stability of the connection relationship.

[0062] The first limiting structure 12 and the second limiting structure 23 are preferably disposed on the plane that contacts the connecting seat 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm. This is beneficial to ensure that the connecting seat 21 at the end of the surgical instrument 2 and the support frame 1 at the end of the robotic arm can make better contact and limit the movement, thus ensuring the limiting effect.

[0063] For example, the first limiting structure 12 includes a first limiting surface; the second limiting structure 23 includes a second limiting surface; the first limiting surface and the second limiting surface are connected in a relative fit.

[0064] Specifically, by configuring a first limiting surface on the support frame 1 at the end of the robotic arm and a second limiting surface on the connecting seat 21 at the end of the surgical instrument 2, the first and second limiting surfaces can be correspondingly fitted and limited when the support frame 1 at the end of the robotic arm and the connecting seat 21 at the end of the surgical instrument 2 are assembled, thus ensuring the limiting effect.

[0065] Preferably, a limiting edge is provided on the side where the first limiting surface and the second limiting surface are fitted and connected, so as to ensure that the limiting edge plays an auxiliary fixing effect after the first limiting surface and the second limiting surface are fitted and connected.

[0066] For example, the conductive structure 24 is a conductive spring.

[0067] Specifically, by selecting a conductive spring sheet for the conductive structure 24, the elasticity of the conductive spring sheet can be used to better conduct electricity after the first electrical connector 3 and the second electrical connector 4 are plugged in, thus ensuring the effectiveness of use.

[0068] Among them, the conductive spring is preferably a conductive column. The conductive spring of the column can achieve a larger conductive area and has better elasticity, so as to achieve a better conduction effect.

[0069] For example, the second electrical connector 4 is provided with a plurality of wiring holes.

[0070] Specifically, by configuring multiple wiring holes on the second electrical connector 4, when multiple wiring signals from the connector 21 at the end of the surgical instrument 2 need to be uploaded to the support frame 1 at the end of the robotic arm, they can all be routed through multiple wiring holes, thereby improving the standardization of wiring.

[0071] For example, it also includes an indicator unit; the indicator unit is connected to the above-mentioned connection device, and the indicator unit is used to display the working status of the above-mentioned connection device.

[0072] Specifically, by connecting the indicator unit to the connecting device, when the connecting device is on, the connecting line and the like have a circuit, and the indicator unit receives a signal to indicate that the connecting device is in the assembled state; when the connecting device is off-circuited, the connecting line is off-circuited, and the indicator unit receives a signal to indicate that the connecting device is in the unassembled state.

[0073] The indicating unit may include a detection component and a display component. The detection component detects whether the connection device is in a conductive state. When conductive, the display component displays a first state; when not conductive, the display component displays a second state. For example, the display component may be an indicator light; when the connection device is in a conductive state, the indicator light is green; when the connection device is not conductive, the indicator light is red.

[0074] For example, the above-mentioned plugs and sockets are in multiple sets.

[0075] Specifically, by selecting multiple sets of plugs and sockets, multiple points of connection can be made when the support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2 are connected, ensuring the reliability and stability of the connection.

[0076] Among them, the plug and socket can preferably be multi-hole plugs and sockets to ensure the reliability and stability of the connection.

[0077] like Figure 8 As shown, a patient surgical platform includes a robotic arm, a surgical instrument 2, and the aforementioned connecting device; the connecting device is used to connect the support frame 1 at the end of the robotic arm and the surgical instrument 2.

[0078] Specifically, the support frame 1 at the end of the robotic arm is electrically connected to the connector 21 at the end of the surgical instrument 2 through a connecting device. This avoids the need for the signal line from the connector 21 at the end of the surgical instrument 2 to the support frame 1 at the end of the robotic arm to be connected between the support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2. This achieves the integration and modularization of the various parts of the support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2. Signal transmission can be achieved simply by electrically plugging the support frame 1 at the end of the robotic arm and the connector 21 at the end of the surgical instrument 2. This method is convenient to operate and highly safe.

[0079] In summary, the connection device and patient surgical platform provided by this utility model have the following features: the first electrical connector 3 is installed on the support frame 1 at the end of the robotic arm, integrating a connecting wire and a plug. The plug is preferably an anti-misinsertion structure to ensure correct connection direction. The second electrical connector 4 is installed on the connector seat 21 at the end of the surgical instrument 2, integrating a socket. The socket has elastic contact to ensure stable and reliable connection. A guide structure is configured between the first electrical connector 3 and the second electrical connector 4. The guide structure ensures that the plug and socket can automatically align during connection, avoiding misinsertion or connection failure. When the first electrical connector 3 of the support frame 1 at the end of the robotic arm is aligned with the second electrical connector of the connector seat 21 of the surgical instrument 2, the guide structure and the limiting structure ensure precise docking of the plug and socket. With the plug and socket aligned, the connecting wire is automatically connected. By using the unlock button on the plug or by pulling out the plug, the first electrical connector 3 and the second electrical connector 4 are separated, and the connecting wire moves out with the end of the robotic arm, preventing the connecting wire from hanging or breaking. The connection device provided by this utility model features a modular design and a plug-in connection method, making disassembly and installation more convenient. The guide structure and limiting structure ensure accurate connection, avoiding misalignment or connection failure, preventing the connection wire from hanging or breaking, reducing inspection and maintenance costs. The anti-misinsertion design and elastic contact ensure stable connection, avoiding signal interruption, improving the reliability, safety and maintenance efficiency of the system, and is suitable for high-precision surgical robot systems.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
