First Claim
1. A surgical device comprising:
- an end effector comprising an ultrasonic blade to treat tissue;
a transducer coupled to the end effector and configured to energize the end effector;
a trigger actuatable to cause the end effector to be energized; and
a circuit in communication with the trigger, wherein the circuit is configured to;
determine that a first force is applied to the trigger;
after determining that the first force is applied to the trigger, energize the end effector at a first level;
determine that a second force is applied to the trigger, wherein the second force is greater than the first force; and
after determining that the second force is applied to the trigger, energize the end effector at a second level, wherein, at the second level, a value for at least one characteristic selected from an amplitude of the end effector or a power delivered to the end effector is higher than a value for the at least one characteristic at the first level,wherein the circuit is configured to delay by a first period of time between indicating a change in the force applied to the trigger from the first force to the second force and a change from driving the end effector at the first level to driving the end effector at the second level, wherein the first period of time is sufficient to give a user a warning about the change in the force.

Abstract
A surgical device comprising an end effector is disclosed. The surgical device comprises a trigger actuatable to cause the end effector to be energized and a circuit in communication with the trigger. The circuit is configured to, when a first level of force is applied to the trigger, drive the end effector at a first level, when a second level of force is applied to the trigger, drive the end effector at a second level, and, delay by a first period of time between indicating a change in the force applied to the trigger from the first level of force to the second level of force and a change from driving the end effector at the first level to driving the end effector at the second level, wherein the first period of time is sufficient to give a user a warning about the change in the force.

13. An ultrasonic surgical system for treating tissue, the system comprising:
-
an ultrasonic transducer; an end effector comprising an ultrasonic blade coupled to the ultrasonic transducer; a switch having a first position and a second position; and a generator in communication with the switch and the ultrasonic transducer, wherein the generator is configured to; when a first level of force is applied to the switch, provide a first drive level to the ultrasonic transducer; and when a second level of force is applied to the switch, provide a second drive level to the ultrasonic transducer, wherein there is a delay by a first period of time between indicating a change in the force applied to the switch from the first level of force to the second level of force and a change from driving the end effector at the first drive level to driving the end effector at the second drive level, wherein the first period of time is sufficient to give a user a warning about the change in the force. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
