DEVICES, SYSTEMS, AND METHODS FOR GRASPING, TREATING, AND DIVIDING TISSUE
First Claim
1. A surgical system, comprising:
- an end effector assembly including first and second jaw members;
a motor assembly coupled to the end effector assembly and operable to move the jaw members between a spaced-apart position and an approximated position for grasping tissue therebetween;
an energy source coupled to the end effector assembly and operable to supply energy to the jaw members to seal tissue; and
a controller including a processor and a non-transitory computer-readable storage medium storing a control program that, when executed, causes the processor to;
activate the motor assembly, once it is determined that tissue is present between the jaw members, to move the jaw members from the spaced-apart position to the approximated position to grasp tissue;
activate the energy source, once tissue is grasped between the jaw members, to supply energy to the jaw members to seal tissue grasped between the jaw members; and
activate the motor assembly, once it is determined that tissue sealing is complete, to move the jaw members from the approximated position to the spaced-apart position to release sealed tissue.

Abstract
A surgical system includes an end effector assembly, a motor assembly, an energy source, and a controller. The controller activates the motor assembly, once it is determined that tissue is present between jaw members of the end effector assembly, to move the jaw members from a spaced-apart position to an approximated position to grasp tissue. The controller further activates the energy source, once tissue is grasped between the jaw members, to supply energy to the jaw members to seal tissue grasped between the jaw members. The controller further activates the motor assembly, once it is determined that tissue sealing is complete, to move the jaw members from the approximated position to the spaced-apart position to release sealed tissue. The system may further be configured to cut tissue once it is determined that tissue sealing is complete but before moving the jaw members to the spaced-apart position.

9. A surgical system, comprising:
-
an end effector assembly including first and second jaw members; a knife assembly including a knife movable relative to the end effector assembly; a motor assembly coupled to the end effector assembly and the knife assembly, the motor assembly operable to move the jaw members between a spaced-apart position and an approximated position for grasping tissue therebetween, and operable to move the knife relative to the end effector assembly between a retracted position, wherein the knife is disposed proximally of the jaw members, and an extended position, wherein the knife extends between the jaw members to cut tissue disposed therebetween; an energy source coupled to the end effector assembly and operable to supply energy to the jaw members to seal tissue; and a controller configured to; determine whether tissue is present between the jaw members and activate the motor assembly, if it is determined that tissue is present between the jaw members, to move the jaw members from the spaced-apart position to the approximated position to grasp tissue between the jaw members; activate the energy source to supply energy to the jaw members to seal tissue grasped between the jaw members; determine whether tissue sealing is complete and activate the motor assembly, if it is determined that tissue sealing is complete, to move the knife from the retracted position to the extended position to cut tissue sealed tissue grasped between the jaw members; and activate the motor assembly to move the jaw members from the approximated position to the spaced-apart position to release sealed and cut tissue. - View Dependent Claims (10, 11, 12, 13, 14)

15. A surgical system, comprising:
-
an end effector assembly including first and second jaw members and a cutting member disposed on one of the jaw members; a motor assembly coupled to the end effector assembly and operable to move the jaw members between a spaced-apart position and an approximated position for grasping tissue therebetween; an energy source coupled to the end effector assembly, the energy source operable to supply energy to the jaw members to seal tissue and to supply energy to the cutting member to cut tissue; and a controller configured to; determine whether tissue is present between the jaw members and activate the motor assembly, if it is determined that tissue is present between the jaw members, to move the jaw members from the spaced-apart position to the approximated position to grasp tissue between the jaw members; activate the energy source to supply energy to the jaw members to seal tissue grasped between the jaw members; determine whether tissue sealing is complete and activate the energy source, if it is determined that tissue sealing is complete, to supply energy to the cutting member to cut sealed tissue grasped between the jaw members; and determine whether tissue cutting is complete and activate the motor assembly, if it is determined that tissue cutting is complete, to move the jaw members from the approximated position to the spaced-apart position to release sealed and cut tissue. - View Dependent Claims (16, 17, 18, 19, 20)
