Surgical Staples TRIZ Cases

Thermally bonded resilient tissue cushion elements secure surgical stapler adjuncts, reducing bleeding and tissue tearing during fastening.

Relief elements create a recess in the jaw assembly to receive previously formed clips, preventing interference and damage during subsequent clip application.

A tapered implant coil rotates tissue inwardly to compress and seal a perianal fistula tract, preventing reinfection while preserving sphincter function.

A powered in-line handle assembly integrates actuators and a motor system to enable single-handed operation of surgical devices.

Active reversible connection mechanism secures surgical patches to deployment devices using resilient clips and wire actuators.

Radial staple slots and a pivotable anvil head improve blood perfusion and hold strength while reducing tissue necrosis risk during anastomosis.

A coil spring urges a cut ring away from an annular knife after firing, preventing sticking that blocks anvil head tilting.

Segmented convex portions engage recesses via elasticity to prevent uncontrollable rotation of the surgical stapler head.

A closure driving mechanism uses a one-way valve and air cavity to dampen jaw opening speed in medical staplers.

A surgical brace device anchors splint members across stapled tissue to absorb dynamic tensile stress loads from organ motion.

A detachable tissue anchor magazine enables sequential deployment of multiple anchors through a single shaft without removing the delivery device.

Dynamic tilting of the anvil head reduces projected size during delivery while restoring full orientation at the surgical site.

Resilient buttress bands extend beyond stapler jaws to maintain alignment and prevent wound closure gaps without increasing device complexity.

An anvil sleeve with an arm engages the anvil head to provide tilting force, overcoming insufficient spring biasing.

A medical stapler adapter uses a transmission mechanism to drive a rotation locking slider that secures the connecting mechanism.

Rotating cam ring engages knife carrier to simplify loading unit attachment and removal.

Nonplanar jaw surfaces improve tissue positioning precision while a separate firing trigger prevents inadvertent stapling during minimally invasive procedures.

Cartridge channel interlock prevents displacement on thick tissue by securing fastener cartridge with transverse protrusions and recesses.

Curved and serrated blade segments reduce initial contact area to slice thick tissue efficiently.

A buttress carrier assembly uses distal and lateral posts to secure surgical material.

Segmented delivery allows the helical fastener to pass through narrow endoscope channels, enabling secure tissue clamping without large instrument profiles.

An articulating anvil retainer assembly enables secure attachment of circular stapling components through pivotal engagement mechanisms.

Telescoping sections extend to grip small pediatric tissue, resolving the contradiction between structural rigidity and size adaptability.

Coining refines staple pockets to resolve angular alignment contradictions in circular surgical stapler manufacturing.

Segmented undulated rings increase operating diameter and elasticity to prevent stenosis during equipment withdrawal.

A movable tissue guide engages the anvil assembly to resolve misalignment between cartridge and anvil assemblies during stapling.

A coil tissue fastener deploys via a rotating stylet to join hollow organs while preventing axial deviation and leakage.

Segmented bioabsorbable layers distribute clamping force to ensure consistent staple placement and reduce tissue damage.

A surgical buttress uses a proximal tab engaging a cartridge protrusion to secure the material.

A surgical handle assembly uses a driving pawl and latch to move a toothed rack for precise cartridge clamping.

A tissue anchor insertion device uses a spring-elastic retaining tongue to transmit pressing force directly to anchors.

Cantilever pins on a ring pierce target vessels to stabilize connections, eliminating time-consuming manual stitching during blood flow.

A stapler uses multiple pushers to eject staples in groups, reducing operator force.

Segmented locking elements within an integrated collar enable rapid attachment while maintaining connection reliability for linear or rotary devices.

Hydrophobic-hydrophilic adjunct materials seal staple holes and reduce inflammation while providing structural support for healing tissue.

Retaining features on a frame secure adjunct material to surgical end effector jaws, reducing staple-induced tissue leaks and inflammation.

A biocompatible fiber matrix adjunct material delivers medicants to colon tissue alongside surgical staples.

Guide grooves constrain the blade section along a curved cartridge path, reducing frictional resistance that causes unstable movement during tissue dissection.

Longitudinal ribs on the anvil retainer engage shell housing slots to prevent rotation, eliminating spline misalignment that causes staple malformation.

Segmented surgical buttress with pre-formed attachment features prevents shifting during assembly while reinforcing staple lines against tearing.

Vertical pawl locking and grasping pawl mechanisms prevent actuation shaft advancement during tissue manipulation, eliminating inadvertent staple firing risks.

A sliding sleeve repositions the anastomosis donut during tilting.

Non-parallel jaw surfaces prevent scissoring and misalignment to ensure accurate clip formation.
