Title:
MOTOR DRIVEN ROTARY INPUT CIRCULAR STAPLER WITH LOCKABLE FLEXIBLE SHAFT
Document Type and Number:
WIPO Patent Application WO/2014/099706
Kind Code:
A3
Abstract:
A circular stapler apparatus (210) and method for stapling tissue include a shaft assembly (260) and an anvil (240). The anvil is configured to proximally retract toward the shaft assembly, which at least severs or staples tissue based on a single rotary input. The shaft assembly includes a plurality of joint segments (302, 322, 342), and each joint segment includes a resilient member (318 328, 58). The plurality of joint segments are configured to pivot relative to one another in a first, uncompressed position and are configured to lock against one another to prevent pivoting in a second, compressed position. A first plurality of joint segments defines a proximal portion (412) that is attached to a first cable or shaft. A second plurality of joint segments defines a distal portion (410) that is selectively lockable independent of the proximal portion and that is attached to a second cable or shaft.
