Abstract
A surgical stapler having a remote motorized staple head is provided and generally includes a handle having a control button and a highly flexible cable extending distally from the handle. A housing incorporating a staple assembly is affixed to a distal end of the flexible cable. The housing may incorporate articulating structure to position the staple assembly relative to the remainder of the housing.
Claims18
A surgical stapler, comprising:
- an elongate member;
- and
- a stapler head positioned at a first end of the elongate member, the stapler head including:
- a housing including a motor disposed therein;
- a staple assembly positioned distally of the housing;
- an articulating section extending between and interconnecting the housing and the staple assembly, the articulating section selectively articulatable to articulate the staple assembly relative to the housing;
- and
- a flexible drive member extending through the articulating section, the flexible drive member operably coupled between the motor and the staple assembly, the flexible drive member selectively translatable through the articulating section for driving the staple assembly.

A surgical stapler, comprising:
- an elongate member;
- and
- a stapler head positioned at a distal end of the elongate member, the stapler head including:
- a housing including a motor disposed therein;
- a staple assembly including a staple cartridge configured to retain a plurality of surgical staples therein and an anvil assembly pivotably coupled to the staple cartridge, the anvil assembly being moveable with respect to the staple cartridge between an open position and a closed position;
- an articulating section interconnecting the housing and the staple assembly, the articulating section configured to permit articulation of the staple assembly relative to the housing;
- and
- a flexible camming beam extending through the articulating section and operably coupled between the motor and the staple assembly, wherein the motor is configured to drive translation of the flexible camming beam through the articulating section for moving the anvil assembly from the open position to the closed position and for firing staples from the staple assembly through tissue grasped between the staple cartridge and anvil assembly.
