Abstract
A surgical stapling device includes a body portion and a tool assembly. The body portion includes a base member that defines a longitudinal slot and spaced keyways. The tool assembly includes a mounting member that defines a channel having an open end that is dimensioned to receive the base member of the body portion. The mounting member includes locking tabs that are positioned within the channel. Each of the locking tabs is configured to be received within one of the spaced keyways of the base member to releasably secure the tool assembly to the body portion.
Claims19
A surgical device comprising:
- an adapter assembly including a proximal portion and a distal portion, the proximal portion including a housing and the distal portion including a base member pivotally supported by the housing, the base member defining a longitudinal slot and spaced keyways that are positioned on opposite sides of the longitudinal slot, the spaced keyways configured to receive locking tabs of a tool assembly to releasably secure the tool assembly to the base member;
- and
- a drive assembly extending between the housing and the base member, the drive assembly having a distal portion including a working end having an upper beam, a lower beam, and a vertical strut extending between the upper beam and the lower beam, the drive assembly being movable between a retracted position in which the vertical strut of the working end of the drive assembly is positioned within the longitudinal slot of the base member and an advanced position in which the working end is positioned distally of the base member.
