A minimally invasive technique for harvesting saphenous veins and the like for use as autografts in coronary artery bypass grafting surgery include a microsurgical instrument adapted to be demountably secured to the distal end of an endoscope. The instrument is inserted through an entry incision in the patient's skin, at the end of the endoscope which is used by a surgeon to advance the instrument along the saphenous vein, using the vein as a guide for the instrument. The instrument is tapered to provide initial separation of surrounding tissues from the vein, and cutting means supported by the instrument and viewed via the endoscope allow dissection of all tissues and side branch vessels from the saphenous vein. The instrument further provides a protective hood which prevents tissues or skin from blocking the endoscope. The desired length of saphenous vein is transected and is extracted via the entry incision. The technique minimizes trauma to the patient and to the saphenous vein graft.read more

Endoscopic surgical access devices and methods of articulating an external accessory channel
TL;DR: In this paper, the authors present a set of devices and methods for detachably engaging an insertion section of an endoscope and selectively articulating an endoscopic surgical access channel, which can control the position and orientation of a diagnostic, monitoring, scope, sewing device, cutting device, suturing device, forceps, grabbing device, instrument, or other tool within the visual field beyond the distal opening of the endoscope.
Patent
Endoscopic system and method for positioning an indwelling tube
TL;DR: An endoscope including a fixing member detachably mounted to a distal end portion of an endoscope insertion part for detachably fixing and holding an indwelling tube or a guide member for guiding the insertion part is described in this paper.

Bipolar electrosurgical forceps
Mark A. Rydell,Corey J. Kulseth +1 more
TL;DR: In this article, a hand operable bipolar forceps instrument comprising two interfacing pivotal blade member's which are each an electrode individually pivotable in relation to each other, is presented, where the movement of the blades is effectuated by two respective electrically-conductive rigid rods, each coupled to a respective blade member, extending through an elongated tubular member having disposed at its proximal end a scissors type handle whose hand operation causes the blade members to pivot in relation with each other.

Bi-polar electrosurgical endoscopic instruments and methods of use
TL;DR: In this paper, bipolar electrodes on opposing movable members (18, 19) are used to pass a high frequency current through tissue for simultaneously severing or manipulating the tissue and causing hemostasis of the tissue.
