  • Publication number: 20240237981
    Abstract: A surgical stapler and a control method therefor. A control part of the surgical stapler is used to acquire a real-time drive current value and a jump current average value of a drive part; then, determine the difference value between the drive current value at a current moment and the drive current value at a previous moment; compare the difference value to the jump current average value, if the difference value is greater than the jump current average value, control the drive part to stop working. Thus, an operator does not have to determine by his or herself whether anastomosis action is completed before operating the surgical stapler, thereby increasing surgical efficiency.

  • Publication number: 20220387040
    Abstract: An anastomat includes a body tail plate and a battery pack, a triode and a controller. The elastic sheets for positive and negative signals of the body tail plate are connected to the upper and lower signal conducting sheets in the battery pack by means of a mechanical mechanism, and afterwards are used for outputting a signal for the anastomat. After the power clamping reed of the body tail plate is connected to the power output conducting plate in the battery pack by means of a mechanical structure, the power clamping reed is used for outputting power for the anastomat. The controller is used for controlling the operation of a battery panel in the battery pack, wherein the base of the triode is connected to a pin corresponding to the controller, the collector of the triode is connected to the battery panel, and the emitter of the triode is grounded.
