Publication number: 20190000495Abstract: Surgical devices are provided having power-assisted or fully powered jaw closure. The devices herein generally include a handle portion, an elongate shaft, and an effector having first and second jaws configured to engage tissue. A motor and one or more compression springs can be operatively coupled, and activation of the motor can compress the spring(s) to reduce the amount of user supplied force to compress tissue between the jaws. In some embodiments, the devices can be configured to regulate an amount of compression applied by the jaws prior to, during, and/or after cutting of the tissue to promote hemostasis. For example, the devices can include sensors, processors, and/or other components that analyze data indicative of tissue type and tissue load. Based on this feedback, the device can automatically adjust the amount of compression or energy applied to the tissue to seal the tissue.Type: ApplicationFiled: July 9, 2018Publication date: January 3, 2019Inventors: John A. Hibner, Catherine A. Corbett, Scott R. Bingham, Chad P. Boudreaux, Carl J. Draginoff, JR., Geoffrey S. Strobl, Eric N. Johnson

Publication number: 20160296270Abstract: Devices and methods are described herein for providing enhanced power to a surgical device from a secondary power supply that operates in parallel to a primary power supply that provides power for therapeutic functions of the device. The secondary power supply can provide additional power for the therapeutic functions of the device, and/or it can provide power for non-therapeutic functions of the device such as sensors, displays, motors, etc. Subsystems powered by the primary power supply can be wholly isolated from subsystems powered by the secondary power supply, thus helping to prevent faults in one subsystem from affecting the other and providing secondary power without the need to modify the subsystems powered by the primary power supply. According to any of the systems described herein, additional power can thus be supplied to the device without affecting the structure and/or function of existing subsystems configured to supply primary power.Type: ApplicationFiled: April 10, 2015Publication date: October 13, 2016Inventors: Geoffrey S.

Publication number: 20150327882Abstract: An ultrasonic assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The balanced blade provides a rounded distal end and concave edges to promote fine dissection and cutting in a variety of surgical procedures. The blade is curved for improved visibility at the blade tip and is designed to provide a multitude of tissue effects: coagulation, cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly features hand activation configured to provide an ergonomical grip and operation for the surgeon. The assembly further features user selectable blade rotation. A finger switch is placed in the range of the natural axial motion of the user's index finger, whether gripping the surgical instrument right-handed or left handed.Type: ApplicationFiled: July 23, 2015Publication date: November 19, 2015Inventors: Stephen J.

Patent number: 9089327Abstract: An apparatus comprises an end effector, an elongate shaft, and a handle assembly. The end effector is operable to grasp tissue. The elongate shaft extends between the end effector and the handle assembly. The handle assembly comprises a body portion, a trigger, and a trigger return lever. The trigger is movable relative to the body portion from a home position to an actuated position, and is thereby operable to control the end effector to selectively grasp tissue. The trigger includes a cam feature. The trigger return lever is positioned to engage the cam feature of the trigger. The trigger return lever is configured to bias the trigger toward the home position during at least part of a range of motion of the trigger from the home position to the actuated position.Type: GrantFiled: September 19, 2012Date of Patent: July 28, 2015Assignee: Ethicon Endo-Surgery, Inc.Inventors: Barry C.
