Circular stapler introducer with radially-openable distal end portion
First Claim
1. An introducer for introducing a surgical circular stapler having a handle portion, an elongated shaft protruding from the handle portion, and stapling head coupled to the elongated shaft into a patient, said introducer comprising:
- a hollow flexible sheath having a distal end and an open proximal end, said hollow flexible sheath sized to receive the stapling head and at least a portion of the elongated shaft therein;
a radially-openable barrel member attached to a distal end of said hollow flexible sheath and defining an opening for receiving the stapling head therein,a rigid cap member hingably attached to said radially-openable barrel member and movable between a closed position wherein said rigid cap member covers a distal end of said opening in said barrel member and open position wherein said rigid cap member is movable to a position exposing said distal end of said opening in said barrel member; and
a latch member in engagement with a pair of opposed ends of said radially-openable barrel member, said latch member being selectively movable from a latched position engaging said opposed ends of said barrel member and retaining said rigid cap member in said closed position and an unlatched position wherein said opposed ends may move radially away from each other to enable said rigid cap member to move to said open position.

Abstract
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 radially-openable barrel member is attached to a distal end of the hollow flexible sheath to define an opening for receiving the stapling head therein. A rigid cap member is hingably attached to the radially-openable barrel member and is movable between a closed position wherein the rigid cap member covers a distal end of the opening in the barrel member and open position wherein the rigid cap member is movable to a position wherein the distal end of the opening is exposed. A releasable latch member is provided to engage and release opposed ends of the radially-openable barrel member.

16. An introducer for introducing a surgical circular stapler having a handle portion, an elongated shaft protruding from the handle portion, and stapling head coupled to the elongated shaft into a patient, said introducer comprising:
-
a hollow flexible sheath having a distal end and an open proximal end, said hollow flexible sheath sized to receive the stapling head and at least a portion of the elongated shaft therein; a radially-openable barrel member attached to a distal end of said hollow flexible sheath and defining an opening for receiving the stapling head therein when said radially-openable barrel member is in a latched position, a rigid cap member hingably attached to said radially-openable barrel member and movable between a closed position wherein said rigid cap member is retained in position covering a distal face of the stapling head when the stapling head has been inserted to a fully inserted position therein and an open position exposing the distal face of the stapling head; and latch means for releasably retaining opposed ends of said radially-openable barrel member in said latched position and, upon application of a release motion thereto, urging said opposed ends of said radially-openable barrel member away from each other to an unlatched position. - View Dependent Claims (17)
