摘要： 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. A force-limiting mechanism provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time.
摘要翻译：用于切断和焊接组织，特别是血管的手术设备和方法。该装置包括细长轴，其在其远端具有一对相对可动的钳口。其中一个钳口上的第一加热元件适于加热至第一温度并在组织内形成焊接区域，而其中一个钳口上的第二加热元件适于加热至第二温度并切断组织在焊接区域内。第一和第二加热元件可以设置在相同或相对的夹爪上。设置在细长轴的近端的控制手柄包括用于打开和关闭钳口的控制器，并且可以包括用于通过第一和第二加热元件发送电流的致动器。第一和第二加热元件可以串联电连接，并且第一加热元件可以分叉，使得其作为第二加热元件传导大约电流的一半。设置在控制手柄，细长轴或钳口内的力限制机构限制由钳口施加到组织上的压力，以确保组织被切断并且端部在短时间内有效地焊接。

摘要： A vessel harvesting system that is suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The system includes a vessel harvesting tool with an elongated cannula and a plurality of surgical instruments therein for separating the target vessels from the surrounding tissue and side branches. The harvesting tool includes a modular handle unit with a base attached to the elongated cannula and a sled that can adapt the base to various types of vessel severing/securing tools, such as tissue welders, bipolar scissors, and bipolar bisectors. The handle unit may be relatively rigid and integrated with the various tool movement controls to facilitate one-handed operation by a user. A severing/securing tool rotation mechanism may be incorporated within the handle and operated by a thumbwheel or other such mechanism. The vessel harvesting system may also provide distal CO2 insufflation for enhanced maintenance of the operating cavity.
