Publication number: 20190380688Abstract: Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end.Type: ApplicationFiled: August 27, 2019Publication date: December 19, 2019Applicant: MAQUET CARDIOVASCULAR LLCInventors: Liming LAU, Peter L. CALLAS, Michael C. STEWART, Geoffrey H. WILLIS, Ryan C. ABBOTT, Charles J. ADAM, Kimberley D. BARKMAN, Albert K. CHIN, Kenny L. DANG, Joseph N. LAMBERTI, Arthur M. LIN, Ravinder D. PAMNANI

Publication number: 20190249759Abstract: A force transmission mechanism includes a chassis that supports a rotatable arm, which includes a slot. A rotatable lever is supported by the chassis. A protrusion at an end of the lever engages the slot. A sliding drive element is supported by the chassis. A proximal termination of the drive element engages a second end of the lever. The chassis may support an elongate tube with an end effector fixed to the tube. The drive element may extend through the elongate tube. The elongate tube may rotate relative to the chassis. The drive element may rotate in unison with the elongate tube with the proximal termination rotating relative to the fork. The drive element may be a tube that provides a fluid passage to the end effector. The lever may be a bell crank with arms at a right angle.Type: ApplicationFiled: February 8, 2019Publication date: August 15, 2019Applicant: Intuitive Surgical Operations, Inc.Inventor: Ryan C.

Publication number: 20190239965Abstract: A medical device having a force transmission mechanism that includes a chassis having a pivotal support that defines a first axis. An axle is supported by the pivotal support and is free to rotate around the first axis of rotation. The axle defines a second axis of rotation perpendicular to the first axis of rotation. A first control arm is coupled to a first end of the axle and is free to rotate around the second axis of rotation. A second control arm is coupled to an opposite second end of the axle and is free to rotate around the second axis of rotation independently of the first control arm. A distal component is coupled to an elongate tube that is coupled to the chassis. Four drive elements coupled to the control arms control motion of the distal component. In one implementation, the medical device is a teleoperated surgical instrument.Type: ApplicationFiled: February 6, 2019Publication date: August 8, 2019Applicant: Intuitive Surgical Operations, Inc.Inventor: Ryan C. ABBOTT

Patent number: 10299770Abstract: Components for an endoscopic vessel harvesting system include a vessel dissector and a vessel harvester. In this case, a vessel dissector is provided that is used in conjunction with an endoscope, and comprises: an elongated cannula including a lumen therein for receiving the endoscope; a blunt dissecting tip provided on a distal end of the elongated cannula that permits an operator of the vessel dissector to dissect tissue while viewing internal body structures via an objective lens of the endoscope; and a vessel severing tool extending through at least a portion of the elongated cannula, wherein the vessel severing tool is capable of translating longitudinally relative to the elongated cannula, and wherein the vessel severing tool comprises an electrode-carrying member that is capable of translating circumferentially within an arcuate slot extending through an outer surface of the vessel dissector.Type: GrantFiled: August 24, 2017Date of Patent: May 28, 2019Assignee: MAQUET CARDIOVASCULAR LLCInventors: Geoffrey H.

Publication number: 20170258513Abstract: A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws. A control handle provided on the proximal end of the elongated shaft includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element.Type: ApplicationFiled: April 7, 2017Publication date: September 14, 2017Applicant: MAQUET CARDIOVASCULAR LLCInventors: Liming LAU, Arnold M.
