US 2026/0283613 A1 · SURGICAL STAPLING INSTRUMENTS AND CONTROL SYSTEMS FOR SUCH INSTRUMENTS

Abstract

Surgical stapling instruments and control systems for use with those instruments are provided herein. A surgical stapling instrument comprises an elongate shaft and an end effector with an anvil on a first jaw and a staple cartridge coupled to a second jaw. The instrument further includes a first coupler for adjusting a distance between the distal ends of the anvil and the cartridge and a second coupler for adjusting a distance between the proximal ends of the anvil and the cartridge. This allows the user to independently adjust these distances or gaps to account for variations in tissue thickness across the length of the jaws. The instruments and control systems are particularly useful for dissecting and stapling a relatively long length of tissue, such as the stomach or the lung in sleeve gastrectomy and lung resection procedures.

Dependent claims

A surgical stapling instrument comprising:

an elongate shaft having distal and proximal ends;
an end effector coupled to the distal end of the shaft and defining a longitudinal axis, the end effector comprising an anvil having a proximal end, a distal end and a surface positionable on a first side of an anatomical structure and a cartridge configured to house a plurality of staples and having a proximal end, a distal end and a surface positionable on a second side of the anatomical structure;
a first coupler movably coupling the proximal end of the anvil to the proximal end of the cartridge;
and
