摘要：
Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise a hollow flexible sheath that has a distal end and an open proximal end that is sized to receive a stapling head portion of the circular stapler therein. A rigid cap assembly may be attached to the distal end of the hollow flexible sheath The rigid cap assembly may be configured to selectively move between a closed position wherein a distal face of the stapling head is covered and an open position wherein the distal face of the stapling head is exposed. A portion of the rigid cap assembly has a shape that substantially matches a perimetrical shape of a portion of the stapling head to enable the rigid cap assembly to pass proximally over the stapling head when the introducer is withdrawn from the patient.
