2271761, 227 19, 2271752

Abstract:

A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a carrier that supports a staple cartridge therein, an anvil assembly that is movably coupled to the carrier, and an axial drive assembly that is constructed to move in a distal direction from a start position to an end position through the staple cartridge in response to a drive motion imparted to the axial drive assembly from the surgical stapling apparatus. A firing indicator is provided on at least one of the anvil assembly and housing for indicating a position of the axial drive assembly as the axial drive assembly is driven from the start position to the end position.

US Classification:

2271752, 227 19, 2271751

Abstract:

A surgical stapling apparatus configured for use with disposable loading units. In various embodiments, the surgical stapling apparatus includes a retraction system that interfaces with an actuation shaft that is movably supported within a handle housing. The actuation shaft is configured to move axially within the handle housing from a fully retracted position to a fully fired position in response to manipulation of a movable handle operably mounted to the handle housing. The retraction system serves to automatically retract the actuation shaft to the fully retracted position when the actuation shaft has moved to the fully fired position.

Abstract:

A surgical stapling apparatus. Various embodiments include a rotatable elongated body that extends from a rotatable shroud on handle assembly and has a distal end configured for attachment to a disposable loading unit. The apparatus further includes a lockable rotation system for selectively locking the rotatable shroud to prevent rotation thereof about a longitudinal axis.

US Classification:

2271752, 227 19, 2271761, 606219

Abstract:

A surgical stapling apparatus. Various embodiments include a handle assembly that has a movable handle that is movable through actuation strokes relative to a stationary handle housing. An actuation is shaft supported at least in part within the stationary handle housing and is movable in response to manipulation of the movable handle. Various embodiments further include a firing lock out assembly that is configured to selectively prevent longitudinal movement of the actuation shaft in a distal direction. A firing release trigger is supported on the movable handle for travel therewith and is configured to interface with the firing lockout assembly to selectively release the firing lockout assembly to permit the actuation shaft to move longitudinally in the distal direction upon manipulation of the movable handle.

International Classification:

A61B 17/064

US Classification:

2271761, 227 19, 2271751, 2271801

Abstract:

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

International Classification:

A61B 17/072

US Classification:

2271761, 227 19, 2271751

Abstract:

A surgical stapling instrument including an actuator configured to be retracted relative to the distal end of the disposable loading unit and rotate an anvil between an open position and a closed position. The actuator can include a cam, where the cam can include an arcuate profile having an apex configured to be in contact with the anvil when the anvil is in a closed position. In at least one such embodiment, the anvil can apply a clamping force to the soft tissue prior to the staples being deployed to prevent, or at least inhibit, soft tissue from flowing, or ‘milking’, out of the distal end of the disposable loading unit. In various embodiments, a surgical stapling instrument can include a disposable loading unit having an anvil which can be moved between open, closed, and/or collapsed positions to facilitate the insertion of the disposable loading unit through a trocar.
