1. A medical device, comprising an actuator, a connecting mechanism, and a control mechanism, wherein the control mechanism is connected to the actuator by means of the connecting mechanism;
the control mechanism comprises a firing assembly, a reset mechanism, and a limiting assembly;
the firing assembly is configured to move in a first direction after being fired, so as to realize a first action of the actuator;
the limiting assembly is connected to the firing assembly, and is configured to limit the firing assembly not to move in a second direction after the firing assembly moves a certain distance in the first direction;
the reset mechanism is connected to the limiting assembly; and after the firing assembly is limited not to move in the second direction by the limiting assembly, the reset mechanism is configured to adjust the position of the limiting assembly, such that the limiting assembly releases the limit on the firing assembly to allow the firing assembly to move in the second direction.
