Patent number: 9456868Abstract: An instrument includes a handle portion, an actuator, a shaft, a rigid member, and an angular control mechanism. The shaft has a proximal end and a distal end with an electrode region, and a flexible region in between. Moving the actuator causes portions of the flexible region distal of a pivot region to bend such that an angular orientation and a radial offset of the electrode region reach an angular orientation and a radial offset, respectively, when the actuator reaches the end position. A distal portion of the rigid member defines the pivot region. Moving the rigid member along the shaft causes the pivot region to translate. The radial offset varies depending on the position of the pivot region.Type: GrantFiled: March 31, 2015Date of Patent: October 4, 2016Assignee: Smith & Nephew, Inc.Inventors: Mathew Erle Mitchell, Christopher D. McDonald, Paul Robert Duhamel

Patent number: 9011429Abstract: An instrument includes a handle portion, an actuator, a shaft, a rigid member, and an angular control mechanism. The shaft has a proximal end and a distal end with an electrode region, and a flexible region in between. Moving the actuator causes portions of the flexible region distal of a pivot region to bend such that an angular orientation and a radial offset of the electrode region reach a maximum angular orientation and a maximum radial offset, respectively, when the actuator reaches the end position. A distal portion of the rigid member defines the pivot region. Moving the rigid member along the shaft causes the pivot region to translate. The maximum radial offset varies depending on the position of the pivot region. The angular control mechanism is configured to control the angular orientation such that the maximum angular orientation is same regardless of the position of the rigid member.Type: GrantFiled: June 7, 2012Date of Patent: April 21, 2015Assignee: Smith & Nephew, Inc.Inventors: Mathew Erle Mitchell, Christopher D. McDonald, Paul Robert Duhamel

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
