Abstract
Devices and methods for sternal retraction that reduces bleeding from the cut edges of a sternum and reduces fracturing of the sternum during retraction. The devices and methods involve the use of sternal retractor blades having a certain geometry and inserts placed inside the sternal retractor blades during retraction of the sternotomy incision. The blades and inserts act to tamponade the blood flow from the cut sternal edge and reduce fracturing of the sternum during retraction.
Claims20
A sternal retractor, comprising:
- a retractor arm;
- and
- a blade attached to the retractor arm, the blade comprising a rigid frame comprising a floor wall and a lower side wall, wherein the floor wall and the lower side wall at least partially define an area that is configured to receive a cut sternal edge;
- and
- an insert that is positioned in the area of the rigid frame that is configured to receive a cut sternal edge so as to contact the cut sternal edge when the cut sternal edge is received in the rigid frame, wherein the insert is less rigid than the rigid frame so as to be capable of reducing bleeding from the cut sternal edge.
