Surgical Staples TRIZ Cases

Coil springs in a surgical reload urge the tool assembly to a neutral position, preventing permanent deformation from side loads during storage.

A compressible adjunct with resilient nodules applies spring force to reinforce tissue, preventing staple pull-through and reducing bleeding.

An integral self-dispensing buttress in a surgical stapler releases hemostatic agents upon firing, reducing bleeding while maintaining device simplicity.

A surgical stapler end effector uses asymmetric closure attachment points to generate precise pivotal control from rotary input.

Movable anvil pockets and vertical cartridge movement adjust the tissue gap automatically, ensuring effective hemostasis across varying tissue thicknesses.

Localized anvil cap welding improves staple formation and tissue compression while maintaining manufacturing simplicity.

A compressible bioabsorbable adjunct accommodates varying tissue thickness, enabling consistent sealing and minimizing leakage in surgical staplers.

An asymmetric bushing in a surgical instrument locking mechanism ensures secure engagement and prevents unauthorized operation until proper alignment occurs.

A surgical instrument uses a flexible drive shaft to transmit motion from a motor to an articulatable end effector.

Merging articulation and rotation into a single control member reduces device complexity while enabling single-handed operation of the end effector.

Distinct compositional regions in a surgical stapling adjunct prevent plowing and staple distortion when the cutting knife passes through overlapping materials.

Segmented cantilever beams isolate retaining features from rigid side walls to control force and prevent accidental deployment.

Laser ablation creates precise staple pockets on the anvil, eliminating structural fractures and material accumulation caused by mechanical coining.

A surgical stapling head assembly uses a movable retention member to block staple drivers during insertion.

Hydraulic actuation replaces mechanical drive bands in surgical staplers, resolving power transmission inefficiencies and manual force requirements.

A hydraulic staple cartridge uses pressurized fluid to drive staples evenly across tissue surfaces.

A deformable anvil tip flexes under clamping force to deflect tissue atraumatically, resolving rigid instrument trauma and visibility issues.

A reusable surgical stapling device features a pivotally coupled anvil head and movable support members that enable tilting.

Braking assembly engages brake pads against articulation member to eliminate tremors from firing forces, ensuring precise surgical stapling.
