    • 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.
    • 适用于收集目标血管如隐静脉或桡动脉用于心脏动脉旁路移植手术的血管采集系统。 该系统包括具有细长插管的血管收集工具和其中的多个外科器械,用于将靶容器与周围组织和侧枝分开。 收割工具包括具有附接到细长插管的基座的模块化手柄单元和可以使底座适应各种类型的容器切割/固定工具(例如组织焊接机,双极剪刀和双极平分线)的滑板。 手柄单元可以是相对刚性的并且与各种工具移动控件集成以便于用户的单手操作。 切割/固定工具旋转机构可以结合在手柄内并由指轮或其它这样的机构操作。 容器收集系统还可以提供远端CO 2注入以增强操作腔的维护。
