Surgical Staples TRIZ Cases

A grasping pawl switches the tool assembly between clamping and grasping modes to improve tissue access.

Segmenting the instrument into reusable and disposable parts enables waste reduction while maintaining secure attachment through elastic deformation.

A surgical stapling instrument uses a cable-driven knife assembly with an actuated closure ring for precise tissue manipulation.

A surgical tilt anvil assembly uses a pivotally secured head and tensioning suture to enable controlled position transitions.

Locking member with teeth engages mounting assembly notches to prevent straightening during firing.

Rotatable drive member advances an I-beam via a linkage system to enable tool assembly articulation.

Electromagnets pivot surgical end effectors via magnetic fields, eliminating dual-handed manipulation requirements.

Inflatable pusher bags eject staples sequentially, enabling adjustable staple line length beyond fixed cartridge limits.

Porous hydrophilic polymer absorbs fluid and swells to seal gaps, preventing air or fluid leakage from delicate tissue staple lines.

A reloadable cartridge assembly positions staple formation pockets within 6 millimeters of the distal end to enable precise surgical placement.

An elastic anastomosis device connects intestinal walls through uniform radial compression and dynamic expansion.

Pre-formed tissue pockets in stapling jaws capture and retain biological material, preventing migration from the stapling area under compressive forces.

Elastomeric mounting structure secures annular buttress material to circular staple cartridge assemblies.

Heat-activated glue beads within a fibrin pad matrix provide immediate adhesion and hemostasis, resolving insufficient tissue sealing in endoscopic staplers.

Angled anvil forming pockets align staples to resolve the trade-off between staple formation precision and leg breakage risk near the tissue stop.

Concentric buttress components secure within the anvil and staple cartridge to prevent anastomotic leaks and tissue tears.

A linear cutting stapler uses a positioning pin and slot system to allow single-handed lifting of the device for tissue re-location.

Segmenting the handle and loading units reduces manufacturing costs while maintaining operability through universal interfaces.

Camming surfaces convert linear motion into precise staple ejection, preventing misalignment and tissue damage during deployment.

Segmented adhesive layers prevent staple pull-through and tissue tearing in surgical staplers.

Segmented attachment points distribute load across the buttress, resolving reliability versus complexity trade-offs in stapling assemblies.

A rotary knife blade driven by a mainspring releases via a latch mechanism to slice through wayward staples and tough tissues during anastomosis.

Resilient arms on the locking collar enable detachment of the circular stapling shell assembly, resolving single-use disposal constraints.

Nested hydraulic cylinder and piston rod drive tissue clips from storage to work position, resolving device complexity constraints in confined spaces.

Segmented retainers engage jaw recesses to secure buttress material, preventing tears and pull-through during tissue stapling.

A surgical stapling anvil buttress loading unit integrates a clip and release strap to secure tissue reinforcement materials.

A segmented endoscopic system allows interchangeable end effectors on a fixed shaft, reducing incisions and tissue damage.

Interchangeable buttress assemblies use parallel adhesive layers with matching transverse profiles to prevent staple pull-through and tissue tearing.
