Abstract
A tissue compression sensor system is disclosed. The tissue compression system includes an RF electrode positioned on an end-effector; a first electrical contact positioned on one of an anvil or a channel frame of the end-effector; and a first filter communicatively coupled to the first electrical contact.
Claims18
A tissue compression sensor system comprising:
- an RF electrode positioned on an end-effector;
- a first electrical contact positioned on one of an anvil or a channel frame of the end-effector;
- and
- a first filter communicatively coupled to the first electrical contact.
1 more element
A method for sensing tissue compression, the method comprising:
- overlaying two or more RF signals and transmitting the RF signals to an end-effector;
- returning the two or more RF signals on a common path via electrical contacts on at least one of an anvil or a channel frame of the end-effector;
- and
- filtering the two or more RF signals prior to joining the RF signals on the common path.
