Description

Technical Field

[0001] This invention relates to the field of surgical instruments, and in particular to a stapler with a battery pack and an error-prevention mechanism. Background Technology

[0002] A stapler is a surgical instrument. Currently, laparoscopic staplers mainly include three types: disposable manual laparoscopic staplers, disposable electric laparoscopic staplers, and electric staplers.

[0003] Disposable manual laparoscopic staplers suffer from drawbacks such as laborious operation, unstable anastomosis and cutting, poor consistency in titanium staple formation, and high usage costs. Disposable electric laparoscopic staplers, on the other hand, only allow for replacement of the same length and model of staple cartridge with the same handle, lacking versatility; the handle becomes unusable after using the manual emergency retraction function, and the cost per use is also high.

[0004] Reusable electric staplers are widely used due to their ease of operation and reduced operating costs. Current electric staplers mainly employ two methods: battery-powered and plug-in-powered. Battery-powered staplers are more portable, and their power handles primarily consist of a housing, motor, power transmission mechanism, and battery. The battery provides power to the motor, driving the actuator of the power handle to complete the surgery. With continuous technological advancements, the manufacturing requirements for staplers are also increasing.

[0005] Existing staplers have certain drawbacks in use. In the existing technology, the battery is installed at the lower end of the handle or inside the handle, which makes the lower end feel heavy and unbalanced when held, making it inconvenient to operate. The battery pack does not have an independent installation space, which is inconvenient for the installation, removal and management of the battery pack. At the same time, after the electric stapler is pressed, even if a stapler error is detected, it cannot be stopped in time, which can easily cause operational accidents and bring certain adverse effects to the actual use process. To address these issues, we propose a stapler with a battery pack and an error-proofing mechanism. Summary of the Invention

[0037] Working Principle: This invention includes a stapler body 1, a display 2, a battery pack 3, a handle 4, an anti-slip pad 5, a button with error prevention 6, a cover plate assembly 7, a motor 8, a stapler head 9, a display screen 10, an NFC card reader coil 11, a docking confirmation micro switch 12, a device circuit board 13, a two-strand wire 14, a main power cut-off switch 15, a first ternary lithium battery 16, a second ternary lithium battery 17, a third ternary lithium battery 18, a charging circuit board 19, a display driver chip 20, a boost chip 21, a Type PC-C female connector 22, a data communication cable 23, a charging cable 24, a Type PC-C male connector 25, a charger 26, a motor wire socket 27, a button panel wiring harness 28, and an electrical... The device includes a wiring harness (29), a motor assembly (30), a firing confirmation button (31), a back button (32), a forward button (33), and a connecting cable (34). The battery pack and display screen are installed at the rear of the electric stapler's gun body. The display screen and battery assembly are integrated into a modular structure via a mounting housing, facilitating assembly and disassembly while maintaining the stability of the gun body. This allows for repeated use of the electric stapler. The entire circuit system makes the mechanical movements of the stapler controllable and visible, increasing its ease of use. The firing confirmation mechanism divides the entire anastomosis process into a first and second stage, ensuring safe use of the instrument and preventing user error.

[0038] The battery pack assembly is installed at the rear of the gun body. It contains a charging circuit board and a video driver. The charging circuit board also contains a display driver chip, a boost chip, and a Type-C female connector.

[0039] The anastomosis device has a circuit board inside, which is connected to a firing confirmation button, a motor, a type-C male connector, a main power cut-off switch, a docking confirmation micro switch, and an NFC card reader coil. The NFC chip is placed in the component protective cover, meaning that the NFC chip can be fixed to the component protective cover by insertion.

[0040] Three 17500 lithium batteries are connected in series in the battery pack, and a charging circuit board with a booster chip is added.

[0041] Based on the premise that the battery pack and display assembly are detachable, the following is the overall principle of this system:

[0042] NFC: NFC cards come in four sizes: 30 / 45 / 60 / 75. All four sizes of cards can be used to swipe instruments, and each card corresponds to a specific instrument movement distance.

[0043] Microswitch confirmation: After the components are connected, the microswitch is pressed down by mechanical transmission and closed, confirming that the circuit components have been connected.

[0044] Power cut-off switch: When the instrument malfunctions and cannot operate, this micro switch will be released after the manual return handle is opened, cutting off the power supply to the circuit and turning the display screen black.

[0045] Forward and Backward Buttons: Button Trigger Conditions - The docking microswitch has been triggered and the card has been successfully swiped. Pressing the forward button will move the instrument forward 6.5mm before stopping (the distance is calculated from the number of motor rotations). Releasing the forward button pauses the movement, and the backward button can be used to return the instrument to its mechanical 0 position. Each time the backward button is triggered, the instrument must return to the motor 0 position before the forward button can be triggered again to prevent repeated forward and backward movements from causing errors in the instrument's position. The prototype's two buttons are mechanically controlled and cannot be pressed simultaneously. In this development, the two buttons are independently positioned. To prevent malfunctions caused by simultaneous pressing of the forward and backward buttons, the program controls the instrument to pause and not perform any movement when both buttons are pressed simultaneously.

[0046] Firing Confirmation Button: After the instrument moves to the first stage 6.5mm position, press the firing confirmation button. Then, press the forward button to continue the movement into the second stage. You can pause or reverse at this point (after reversing, you must return to the 0 position). After advancing to 60mm, the forward button becomes inactive. At this point, press the reverse button to return the instrument to the 0 position. Whether the instrument returns to zero midway or after firing the full distance, it is considered a complete firing, and the instrument stops. You must reinstall the new components and swipe the card again before starting a new round of operation.

[0047] The device has a limited number of actions; entering the second stage of the process is considered one use.

[0048] It should be noted that, in this document, relational terms such as first and second (number one, number two), etc., are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
