    • Surgical instruments and methods for making substantially linear incisions, especially through the wall of vessels, such as arteries, specifically designed for coronary artery bypass graft procedures (CABG) on the beating heart. The invention is particularly useful to create the incision in the artery to which a bypass graft is sewn, typically the left anterior descending artery (LAD). The instruments allow incisions to be rapidly made, precisely measured, and cleanly formed so that a bypass graft can be rapidly sewn in place, without undue trauma to surrounding tissue and excessive loss of blood. In one embodiment, a hand-held instrument has a cutting edge formed on the interior edge of a curved blade fixed near the end of the instrument. The tip of the blade has a point for penetrating the vessel wall which may have several alternate shapes to facilitate penetration of the vessel wall while minimizing trauma to the surrounding tissue. In another embodiment the hand-held instrument includes a moveable member which creates an incision by engaging a cutting blade against a stop, cutting tissue therebetween, the stop including a pointed tip similar to the previous embodiment. In another embodiment, the instrument features a motion-canceling member which compensates for the movement of the target surface to be incised. This embodiment has a cutting blade which is manipulated from a handle which is isolated from the movement of the tissue containing or proximate to the target of the incision.

    • The invention is surgical instruments which facilitate substantially linear incisions, especially through the wall of vessels, such as arteries, which have been specifically designed for coronary artery bypass graft procedures (CABG) on the beating heart. The instruments of the invention are particularly useful to create the incision in the artery to which the bypass graft is sewed, typically the left anterior descending artery (LAD). The instruments of the invention allow incisions to be rapidly made, precisely measured, and cleanly formed so that a bypass graft can be rapidly sewn in place. In one embodiment, the invention is comprised of a hand-held instrument with a curved cutting edge formed on the interior edge of a curved or arcuitous segment located near the end of the instrument. The tip of the instrument has a point of penetrating the vessel wall. The point may have several alternate shapes to facilitate penetration of the vessel wall while maximizing the trauma to the surrounding tissue. Another embodiment is comprised of a hand-held instrument with moveable member such that the incision is created by engaging a cutting blade against a stop with the tissue being cut therebetween. This instrument is also constructed to facilitate a rapid linear incisions in a vessel while minimizing the possibility for damage to the surrounding tissue. In another embodiment, the instrument features a motion-cancelling member which compensates for the movement of the target surface to be incised. This embodiment has a cutting blade which is manipulated form handle which is isolated from the movement of the tissue containing or proximate to the target of the incision. The instruments facilitate the invasive cardiac procedures by creating linear incisions quickly without undue trauma to surrounding tissue and without excess loss of blood.
    • 本发明是促进基本上线性切口的手术器械，特别是通过在搏动心脏上专门设计用于冠状动脉旁路移植手术（CABG）的血管如动脉壁。 本发明的器械特别可用于在旁路移植物缝合的动脉中形成切口，通常为左前降支动脉（LAD）。 本发明的仪器允许快速地进行切割，精确地测量和清洁地形成切口，使得旁路移植物能够快速地缝合到位。 在一个实施例中，本发明包括具有弯曲切割边缘的手持式仪器，其形成在位于靠近仪器端部的弯曲或直立部分的内边缘上。 仪器的尖端具有穿透血管壁的点。 该点可以具有几种替代形状，以促进血管壁的穿透，同时使周围组织的创伤最大化。 另一个实施例包括具有可移动构件的手持式仪器，使得通过将切割刀片接合在止动件上而在其间切割的组织而产生切口。 该仪器还构造成便于在容器中快速线性切口，同时最小化对周围组织的损伤的可能性。 在另一个实施例中，仪器具有补偿待切割的目标表面的移动的运动消除构件。 该实施例具有切割刀片，该切割刀片从手柄被操纵，所述切割刀片与包含或接近切口的靶标的组织的运动隔离。 这些仪器通过快速创建线性切口来促进侵入性心脏手术，而不会对周围组织造成不必要的创伤，而不会导致血液过多的流失。
