Patent number: 7207990Abstract: A laparoscopic bipolar electrosurgical instrument can apply a large closure force between its jaws without damaging the small yoke assembly.Type: GrantFiled: June 29, 2005Date of Patent: April 24, 2007Assignee: Sherwood Services AgInventors: Michael John Lands, Stephen Wade Lukianow, Donald Robert Loeffler, James Steven Cunnigham, Kate Ryland Lawes, Daniel Lee Trimberger, II, Mathew Erle Mitchell, Jenifer Serafin Kennedy

Patent number: 7179258Abstract: A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.Type: GrantFiled: April 7, 2004Date of Patent: February 20, 2007Assignee: Sherwood Services AGInventors: Steven Paul Buysse, Dale Francis Schmaltz, Robert Luzzi, Kirk Bryan Olson, Kate Ryland Lawes, Daniel Lee Trimberger, II, Mathew Erle Mitchell, Jenifer Serafin Kennedy

Publication number: 20030018332Abstract: A bipolar electrosurgical instrument for vessel sealing comprises first and second members connected by a pivot. A pair of jaws have opposable seal surfaces that are designed to grasp vascular tissue and conduct bipolar electrosurgical current therethrough. Electrodes on the jaws, including the seal surfaces, are removable and disposable. The jaws of the instrument have mechanical interfaces designed to accept replacement electrodes. The instrument further comprises interlocking ratchets designed to hold a constant closure force between the seal surfaces. Wires extend from the electrodes along one of the members and are connectable to an electrosurgical generator.Type: ApplicationFiled: September 17, 2002Publication date: January 23, 2003Inventors: Dale Francis Schmaltz, Robert Luzzi, David Nichols Heard, Steven Paul Buysee, Kate Ryland Lawes, Daniel Lee Trimberger, Mathew Erle Mitchell, Jenifer Serafin Kennedy
