Abstract

The invention discloses a control device of a surgical instrument, the surgical instrument and a control method of the surgical instrument. The surgical instrument comprises an end effector, a cuttingknife assembly, a transmission mechanism and a motor, wherein the control device comprises a signal source module and a control module; the signal source module is electrically connected to the control module, and the control module is electrically connected to the motor; and the motor drives the end effector and the cutting knife assembly through the transmission mechanism. After the control module receives a signal that the end effector is closed in place, the signal source module sends out a first signal, and after receiving the first signal, the control module starts a squeezing keeping mode; in a squeezing keeping mode, no matter whether a second signal sent by the signal source module is received or not, the control module does not send out a third signal used for instructing the motor to operate so as to drive the cutting knife assembly to move forwards through the transmission mechanism.

Description

technical field [0001] The invention relates to a control device of a surgical instrument, a surgical instrument and a control method thereof. Background technique [0002] As we all know, endocavity cutting staplers have been widely used in intracavity operations such as the abdominal cavity. [0003] Existing endocavity cutting staplers generally include an operating assembly, a shaft assembly longitudinally extending from the operating assembly, and an end effector disposed at the distal end of the shaft assembly. The end effector includes a staple cartridge base and an anvil base pivotally connected to the staple cartridge base for operably supporting the staple cartridge therein, the anvil base being movable between an open position and a closed position Exercise selectively. The operating component includes a body and a transmission mechanism installed on the body. The stapler also includes a motor and a trigger, the trigger can be manipulated to control the operati...
