Abstract
A cooling member for a cautery surgical instrument such as a surgical forceps including a pair of elongate arms joined at an end so as to provide for resilient compressible movement of the arms between a normally open position and a squeezed closed position. The cooling member provides for conduction of heat away from an electrode tip and includes a first portion having a first diameter, and a second portion spaced away from the first portion that transitions from the first diameter to at least one smaller diameter section. A socket is disposed within each arm of the forceps. The socket includes a longitudinal blind hole that is sized so as to releasably receive the smaller diameter section of the second portion, and a catch for engaging a portion of the arm.
