Abstract
Various surgical devices and methods are provided for monitoring and regulating tissue compression and cutting to improve tissue effect. In general, these devices include a handle portion, an elongate shaft, and an effector disposed at a distal end of the shaft and configured to engage tissue. In one embodiment, one or more sensors can be positioned at various locations on the device and can determine a force applied to tissue engaged by the end effector. When the force exceeds a threshold, a notification signal can be issued to a user. In another embodiment, a sensor can determine an amount of current moving between jaws of the end effector and a controller can slow a speed of the cutting element when the sensed current exceeds a threshold amount.
