Surgical Staples TRIZ Cases

Segmented shaft geometry and motorized firing mechanisms enable precise tissue stapling in confined surgical sites.

A spring member separates buttress layers to resolve the contradiction between reliable sealing and efficient removal.

Segmented retainer tabs prevent adjunct dislodgment during shipment while enabling easy post-surgery removal.

A surgical instrument uses a cammed articulation gear to position an end effector at discrete angular increments relative to the shaft.

A laparoscopic device aligns tissue edges using spreader components and graspers.

A fastening member secures a buttress member to an annular wall aperture, resolving positioning difficulties during circular anastomosis procedures.

A brachytherapy delivery device integrates a carrier line and stylet to advance radioactive seeds alongside a buttress element for simultaneous placement.

Interlocking pipe portions with elastic horn-shaped openings align intestinal segments, reducing leakage risk and simplifying laparoscopic procedures.

Nested camming linkages pivot the jaw assembly relative to the shaft, resolving precision constraints in confined endoscopic spaces.

A resilient drive member rotates a surgical tool assembly via elastic deformation to enable large-angle articulation.

Articulated applicators position buttress assemblies on stapler jaws to prevent tissue tearing and bleeding during surgery.

Radially expanding biodegradable compression rings anchor tissue to form anastomoses, reducing leakage risks associated with complex stapling devices.

Snap-connectable anastomotic rings align via guide wire seats, reducing invasiveness and improving surgical precision.

A surgical fastener cartridge integrates a compressible tissue thickness compensator and a gap setting element to control anvil positioning.

A circular stapling instrument separates staple formation and tissue cutting into independent strokes using a snap ring coupling mechanism.

A single pusher actuates alignment, clamping, and stapling plates in surgical devices.

A two-part tissue thickness compensator assembly connects to a surgical stapler staple cartridge via a hinge mechanism.

Nested buttress mount positions reinforcing material inside knife member lumen to prevent anastomotic leaks and tissue tears during stapling.

A surgical stapling instrument uses resettable staple drivers and a cartridge driver to advance multiple staple cartridges sequentially within the shaft.

A manual lever retracts the firing shaft via gear engagement, ensuring tissue release when motor failure prevents automated stapling.

Angled cam pushers in a compact loading unit enable fastener ejection within a 5 mm diameter for pediatric surgeries.

Wedges engage pull tabs on a feeder belt to advance staples, eliminating cartridge exchange delays during minimally invasive procedures.

An articulating link with a mechanical interface prevents reload disengagement during tool assembly articulation, maintaining connection reliability.

A drive assembly actuates a release mechanism to detach anchors securing a surgical buttress from an anvil or cartridge.

An elastic spine assembly and segmented anvil distribute energy to reduce stress concentrations, preventing damage during the staple-firing stroke.
