Abstract
A surgical instrument includes a frame structure defining proximal and distal portions. The proximal portion has an articulating arm for repositionably mounting to a base and the distal portion supporting a stabilizing member. An attachment mounts on the stabilizing member, the attachment being configured and dimensioned such that upon contact with the heart the engaged heart tissue bulges outward. A method of surgery using the attachment includes providing a frame structure defining proximal and distal portions, the proximal portion being repositionably mountable to a base, supporting an attachment on the stabilizng member and engaging heart tissue with the attachment such that the tissue bulges outward to better present the tissue for surgery.
Claims8
A surgical instrument comprising:
- a frame structure defining proximal and distal portions, the proximal portion having an articulating arm for repostitionably mounting to a vase and the distal portion supporting member;
- a shoe-like attachment mountable on the stabillizing member in a slip-fit fashion, an inner periphery of the attachment being configured and dimensioned such that upon contact with the heart the engaged heart tissue bulges outward.
A surgical instrument comprising:
- a frame defining a proximal portion and a distal portion, the proximal portion being repositionably mountable to a base and the distal portion defining a pair of legs;
- a shoe-like attachment mounted on the pair of legs in a slip-fit manner and configured to abut a portion of a patient's heart, the attachment having an inner periphery which varies in width along a length thereof for allowing heart tissue to bulge therethrough.
A method of facilitating heart surgery comprising the steps of:
- providing a frame structure defining proximal and distal portions, the proximal portion having an articulating arm for repositionably mounting to a base and the distal portion supporting a stabilizing member;
- engaging a shoe-like attachment to the stabilizing member in a slip-fit manner, the attachment having an inner periphery which defines an opening varies in width along a length thereof for allowing heart tissue to bulge therethrough on the stabilizing member;
- and
- engaging heart tissue with the attachment such that the tissue bulges outward to better present the tissue for surgery.
