Abstract
An endoscopic surgical instrument assembly including a support sheath, a miniature medical implement member, and a securing mechanism for securing the support sheath and the medical implement member together in fixed relationship. The securing mechanism is adapted for securing the miniature medical implement member and the support sheath to one another when the miniature medical implement member is advanced axially through the support sheath so that the implement member and the support sheath form a co-axial unit. As a result, the support sheath provides rigid support for the miniature medical implement member and prevents the elongated portion thereof from breaking during an endoscopic medical procedure.
