Surgical Staples TRIZ Cases

Tapered reload member prevents premature separation while reducing separation force.

Stiffened buttress region joins cartridge body to eliminate adhesive residues and reduce firing forces during surgical stapling.

A buttress applier cartridge positions reinforcement material on a curved distal tip end effector for surgical stapling.

A surgical stapler switch system prevents premature firing while the power assist mechanism reduces firing force and maintains tactile feedback.

An anvil member applies varying compressive forces to tissue through angled pusher plates.

Stepped tissue contacting surface applies pressure gradient to tissue layers using varying staple heights, improving anastomotic strength and hemostasis.

A surgical tool assembly with a curved distal portion positions termination points on the specimen side to ensure proper staple sealing.

Adapter assembly converts rotary drive shaft rotation into axial translation for surgical end effectors.

A torsion spring pivots a surgical anvil head assembly, preventing locking collar sticking during knife retraction.

Segmented electromechanical design separates reusable motor from disposable loading units to reduce manufacturing costs and prevent inadvertent actuation.

A sloped staple deck varies tissue compression across the cartridge width, preventing edge over-compression damage while ensuring consistent stapling.

Segmenting the sled allows the knife to retract independently when staple drivers jam, preventing tissue contact.

Segmented anvil body and welded cap reduce firing force by managing flexure stresses during tissue stapling.

Resilient tabs snap into anvil slots to secure biodegradable buttress material, reducing bleeding and aiding tissue healing.
