Electrical Surgical Stapling Instrument with Tissue Compressive Force Control
First Claim
1. A surgical stapling instrument, comprising:
- a handle having a stapler-closing device;
a surgical stapling end effector connected to the handle and having a pair of opposing stapling surfaces, at least one of the stapling surfaces operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween; and
at least one variable member operable to receive the compressive force applied to the tissue and to exhibit at least one of mechanical and electrical change associated with the received compressive force, the at least one change influencing a surgical procedure on the compressed tissue.

Abstract
A surgical stapling instrument includes a handle having a stapler-closing device. A surgical stapling end effector is connected to the handle and has a pair of opposing stapling surfaces. At least one of the stapling surfaces is operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween. At least one variable member is operable to receive the compressive force applied to the tissue and to exhibit at least one of mechanical and electrical change associated with the received compressive force. The change influences a surgical procedure on the compressed tissue.

16. A surgical stapling instrument, comprising:
-
a handle having a stapler-closing device; a surgical stapling end effector connected to the handle and having a pair of opposing stapling surfaces, at least one of the stapling surfaces operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween; at least one variable member operable to receive the compressive force applied to the tissue and to exhibit at least one of mechanical and electrical change associated with the received compressive force, the at least one change influencing a surgical procedure on the compressed tissue; and the at least one mechanical and electrical change being dependent upon the received compressive force being at least equal to a pre-determined compressive force that is a biasing force opposing the compressive force received.
