Retraction device for port access multivessel coronary artery bypass surgery

摘要

Surgical instruments that are disclosed for performing port-access or closed-chest coronary artery by pass (CABG surgery). In particular, a surgical retraction device (190) is described which comprises a shaft (191) with proximal and distal ends, a contact surface (192) adjacent to the distal end for manipulating or retracting living tissue within a body cavity and means (194) for applying a vacuum at the contact surface. A surgical retraction device (170) is also described for retracting a body structure with a curved external surface (171) within a body cavity which comprises a rigid shaft (172) with proximal and distal ends, a contact surface (171) near the distal end with a curvature to conform to the external surface of the body structure and a textured porous material (174) attached to the contact surface for frictionally engaging the structure. The distal portion of the shaft, including the contact surface and the porous material, is dimensioned such that it may be introduced into a body cavity through an opening with a maximum diameter of about 12 mm.
