Patent number: 8584919Abstract: A surgical stapling apparatus having an end effector capable of performing a surgical procedure. The surgical stapling apparatus may include a driving pawl that interfaces with a manually actuatable handle. The driving pawl may have a pawl body with a driving tooth thereon that is configured to interact with an actuation shaft such that, as the manually actuatable handle is actuated, the driving tooth interacts with the actuation shaft to cause the actuation shaft to apply the actuation motions to an elongated body operably coupled to the end effector. When the end effector experiences a firing load that exceeds a predetermined magnitude of firing load, the driving tooth moves relative to the pawl body to disengage from the actuation shaft to prevent further transfer of the actuation motions to the elongated body even though the manually actuatable handle continues to be actuated.Type: GrantFiled: February 14, 2008Date of Patent: November 19, 2013Assignee: Ethicon Endo-Sugery, Inc.Inventors: Geoffrey C. Hueil, Mark S. Ortiz, Douglas B. Hoffman, Patrick A. Weizman, Dean B. Bruewer, Frederick E. Shelton, IV, Gregory B. Blair, Chad P. Boudreaux

Patent number: 8435262Abstract: Various exemplary methods and devices are provided for tensioning suture. The methods and devices are particularly useful in surgical suturing applications in which it is desirable to maintain tension on suture being delivered, yet to allow the tension to be released as desired without retracting the suture. Thus, when tension is released, a length of suture extended from the device can remain extended without any tension being applied thereto. Tension is only applied to any additional length of suture that is extended from the device. The tension applied to the suture is proportional to the length of the suture extended from the device until the tension is released and reset.Type: GrantFiled: December 2, 2010Date of Patent: May 7, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Mark S.
