Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a power supply system and a stapler. Background Technology

[0002] Currently, most electric staplers are battery-powered, but this approach has significant limitations in practical applications: it cannot support continuous operation for extended periods. In clinical settings, complex surgeries often require the stapler to operate stably for several hours. Traditional batteries, limited by capacity and discharge efficiency, are prone to running out of power during critical procedures, potentially interrupting the surgical process and requiring additional battery replacements for medical staff. Using high-capacity batteries, on the other hand, increases the size and weight of the device, affecting the dexterity of handheld operation. This power bottleneck is a major factor hindering the efficient use of electric staplers in prolonged surgeries. Utility Model Content

[0003] This application aims to provide a power supply system and an anastomosis device that can provide power to the anastomosis device for a long time.

[0004] The power supply system according to the first aspect of this application includes: The first terminal block is used to electrically connect the battery module of the anastomosis device through the battery mounting slot provided in the anastomosis device; The second terminal block is used to electrically connect an external power plug via a power socket provided on the anastomosis device; A movable component is used to move along with the external power plug when the external power plug is inserted into the power socket; A power supply switching component is disposed on the movable component and is used to move with the movable component; when the external power plug is not inserted, the power supply switching component connects the first terminal group to the power supply circuit of the anastomosis device; when the external power plug is inserted, the power supply switching component connects the second terminal group to the power supply circuit of the anastomosis device.

[0005] The stapler according to a second aspect embodiment of this application includes a power supply system as described in the first aspect embodiment.

[0006] The power supply system and stapler of this application embodiment, when the power plug is inserted into the socket, can push the movable part to move synchronously, thereby driving the power supply switching part to move accordingly, switching it from the position where the first terminal group is connected to the stapler power supply circuit to the position where the second terminal group is connected to the power supply circuit, thus completing the conversion from battery power supply to external power supply. This design can achieve continuous power supply to the electric stapler through external power when the battery power is low, effectively improving the applicability of the stapler. In addition, the embodiment of this application adopts a mechanical method to switch between battery and external power supply modes, without relying on electronic control devices, making the entire switching process highly stable, suitable for surgical scenarios with extremely high requirements for risk control.

[0010] The embodiments of this application are described in detail below. Examples of the 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 are only used to explain this application, and should not be construed as limiting this application.

[0013] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0014] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0015] See Figures 1 to 3 As shown, one embodiment of this application provides a power supply system, which includes: The first terminal block 100 is used to electrically connect the battery module 800 of the anastomosis device through the battery mounting slot provided in the anastomosis device. The second terminal block 200 is used to electrically connect an external power plug via a power socket 900 provided on the anastomosis device; The movable part 300 is used to move with the external power plug when the external power plug is inserted into the power socket 900; The power supply switching component 400 is disposed on the movable component 300 and is used to move with the movable component 300. When the external power plug is not inserted, the power supply switching component 400 connects the first terminal group 100 to the power supply circuit of the anastomosis device. When the external power plug is inserted, the power supply switching component 400 connects the second terminal group 200 to the power supply circuit of the anastomosis device.

[0016] In this embodiment, when the power plug is inserted into the socket, the movable part 300 can be moved synchronously, thereby causing the power supply switching part 400 to move accordingly. This switches the position from connecting the first terminal group 100 to the stapler power supply circuit to connecting the second terminal group 200 to the same power supply circuit, thus completing the conversion from battery power to external power supply. This design allows for continuous power supply to the electric stapler via external power when the battery power is low, effectively improving the applicability of the stapler. Furthermore, this embodiment uses a mechanical method to switch between battery and external power supply modes, eliminating the need for electronic control devices. This results in extremely high stability throughout the switching process, making it suitable for scenarios with extremely high risk control requirements, such as surgery.

[0017] The aforementioned first terminal group 100 may include a first connection terminal and a second connection terminal. The first connection terminal is connected to one pole of the battery module 800 via a wire, and the second connection terminal is connected to the other pole of the battery module 800 via a wire.

[0018] The aforementioned second terminal block 200 may include a third connection terminal and a fourth connection terminal. The third connection terminal is connected to one pole of the power socket 900 via a wire, and the fourth connection terminal is connected to the other pole of the power socket 900 via a wire. It should be noted that when using AC power, the AC power can be converted to DC power by an external AC-DC converter before being input to the power socket 900.

[0019] The first and third connection terminals can be mounted on one PCB board 700, and the second and fourth connection terminals can be mounted on another PCB board 700. It is understood that when the movable component 300 moves, it can drive the power supply switching component 400 to move, allowing the control circuit of the connector to be connected to the first terminal group 100 or the second terminal group 200 via the power supply switching component 400, thereby enabling power supply from the battery module 800 or an external power source.

[0020] Specifically, the first and third connection terminals can be connected to the ground wire of the control circuit. Subsequently, the power supply switching component 400 can be moved to select whether to connect the second or fourth connection terminal to the power supply line, thereby achieving the switching of the power supply.

[0021] The aforementioned movable component 300 can be movably mounted on the top of the power socket 900, so that when the external power plug is inserted into the power socket 900, the movable component 300 can be lifted and moved, thereby driving the power switching component 400 to move.

[0022] It should be noted that when the external power plug is inserted into the power socket 900, the movable part 300 will move synchronously. Once it has moved into place, it indicates that the external power plug can supply power. At this time, the battery module 800 should have already cut off the power supply. To better achieve this function, the second connection end can be positioned closer to the power socket 900, and the fourth connection end can be positioned further away from the socket. This allows the power switching component 400 to abut against the second connection end when the power socket 900 is not inserted, and the power switching component 400 to abut against the fourth connection end after the power socket 900 is inserted.

[0023] The aforementioned power switching component 400 can be any conductive object with a fixed shape, such as a strip-shaped, block-shaped, or even irregularly shaped metal, alloy, or other conductive material.

[0024] In some implementations, such as Figures 1 to 3As shown, the battery mounting slot is located at the rear of the stapler's gun body, and the power socket 900 is located at the bottom of the stapler's handle.

[0025] In this embodiment, the battery mounting slot is located at the rear of the stapler's gun body, and the power socket 900 is located at the bottom of the stapler's handle. This allows for better configuration of the weight distribution of the power supply system and reduces the inconvenience caused by simultaneously setting up the battery module 800 and the external power supply, thus better serving the operator's operation of the stapler.

[0026] In some implementations, such as Figure 2 As shown, the power socket 900 has a through hole at the top, and the movable part 300 passes through the through hole.

[0027] In this embodiment, a through hole is provided at the top of the power socket 900, and the movable part 300 is inserted through the through hole, which facilitates the power plug to lift the movable part 300.

[0028] In some implementations, such as Figure 2 As shown, the movable component 300 includes a movable block 310 and a lifting limit component 320 disposed at the bottom of the movable block 310. The lifting limit component 320 passes through the through hole, and the power supply switching component 400 is disposed at the top of the movable block 310.

[0029] The aforementioned movable block 310 has a block structure, which allows for better arrangement of the power supply switching component 400 and facilitates the setting of a limit structure to restrict the movement of the movable block 310, thereby improving the stability of the power switching operation.

[0030] The aforementioned lifting limit member 320 can be configured as a columnar structure and set at the bottom of the movable block 310, thereby enabling the movable block 310 to be effectively lifted after the lifting limit member 320 passes through the through hole.

[0031] It is understandable that the lifting limit component 320 and the movable block 310 can have various structural forms, and the specific structural form can be flexibly selected according to the requirements.

[0032] In some implementations, such as Figures 1 to 2 As shown, the aforementioned power supply system also includes: The elastic reset member 500 is disposed in the gun body and forms a compression on the top of the power supply switching member 400 and / or the top of the movable member 300.

[0033] The aforementioned elastic reset member 500 presses against the top of the power supply switching member 400 and / or the top of the movable member 300. This increases the pressing force when the external power plug is inserted into the power socket 900, and releases the pressing force when the external power plug is pulled out. This completes the downward pressing of the top of the power supply switching member 400 and / or the top of the movable member 300, allowing the movable block 310 and the power supply switching member 400 to return to their initial positions, thus achieving electrical connection of the power module.

[0034] It is understandable that when the external power plug is inserted into the power socket 900 and fully inserted, the frictional force may be much greater than the squeezing force provided by the elastic reset member 500, thus allowing the external power plug to be stably positioned in the power socket 900. In some embodiments, a limiting structure for the power plug may also be provided to restrict the movement of the external power plug when it is inserted into the power socket 900 and fully inserted. For example, a snap-fit ​​structure, a pin structure, etc. may be provided.

[0035] In some implementations, the resilient reset element 500 is a spring.

[0036] In this embodiment, the elastic reset component 500 is selected as a spring, which not only achieves elastic reset, but also, as a metal component, provides more stable elastic control for a longer period of time compared to some elastic rubber components.

[0037] In some embodiments, the power supply system described above further includes: A sliding limiter is installed inside the gun body to limit the sliding direction of the movable block 310.

[0038] The aforementioned sliding limiting component can be a limiting plate structure, a limiting groove structure, or other limiting structures.

[0039] Specifically, it can be set as a limit guide rail, and a limit groove can be set on the movable block 310. The movement of the movable block 310 can be restricted by the cooperation of the limit guide rail and the limit groove, thereby achieving better control over the movement distance of the movable block 310.

[0040] In some implementations, such as Figures 1 to 2 As shown, the power supply switching component 400 is a conductive block.

[0041] In this embodiment, the power switching component 400 is set as a conductive block, which is easier to set on the movable block 310 compared to other irregular structures, and also makes it easier for the elastic reset component 500 to squeeze it, so as to achieve better power switching control.

[0042] The aforementioned conductive block can be a copper block, which has good conductivity. Understandably, if it is necessary to further improve conductivity, a silver block or other similar material can be used.

[0043] In some embodiments, the power supply system described above further includes: The power supply detection circuit is electrically connected to the controller inside the anastomosis device and is used to detect the energized status of the battery mounting slot and power socket 900. The display unit 600 is electrically connected to the controller inside the anastomosis device.

[0044] In this embodiment, the power supply detection circuit can detect whether the power socket 900 is powered and whether the contact terminal connected to the battery module 800 in the power installation slot is powered, thereby determining the source of the power. Furthermore, by displaying the source on the display unit 600, the user can determine whether the current power supply has been successfully switched, thus improving the user experience.

[0045] The core controller of the aforementioned controller can be a DSP, ARM, microcontroller, etc. The specific type can be flexibly selected according to the actual data processing requirements. For example, an STM32 series processor can be selected.

[0046] This application also provides a stapler that includes the power supply system described above. Because the stapler has a power supply system, it possesses all the beneficial effects of such a system.

[0047] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
