Patent number: 9532781Abstract: An anvil and anvil delivery system is provided which includes a head assembly and a center rod defining a longitudinal axis. The head assembly defines a transverse axis and is pivotally secured to the rod and movable from an operative position wherein the transverse axis is substantially perpendicular to the longitudinal axis and a tilted position wherein the transverse axis defines an acute angle with respect to the longitudinal axis. A flexible tube is secured to the center rod which includes gradations along the length of the tube. The gradations are positioned to provide an indication of a length of the tube remaining in a patient during removal of the tube from the patient. An adapter is secured to one end of the flexible tube and to the center rod.

Patent number: 8727200Abstract: A surgical stapler which includes or onto which a tool assembly can be mounted for deploying a plurality of surgical fasteners includes a housing having a clamping handle mountable to the housing. The clamping handle is selectively movable to actuate the clamping of tissue. An adapter yoke is included which translates within the housing upon actuation of the clamping handle. The adapter yoke mechanically cooperates with a lead screw to actuate the tool assembly to clamp tissue. A drive assembly is also included for rotating a shaft which mechanically engages the lead screw. Upon selective activation of the drive assembly, the shaft rotates the lead screw to advance a roll nut and force a firing piston into the tool assembly to deform the surgical fasteners through and fasten the tissue.Type: GrantFiled: April 25, 2012Date of Patent: May 20, 2014Assignee: Covidien LPInventor: Philip C.
