Suture Equipments TRIZ Cases

Arcuate needle guide translates suture through angled distal assembly to close large gastrointestinal defects with sufficient closure force.

A corkscrew anchor secures the device in tissue while porosity enables gas exchange, preventing channel closure and eliminating re-navigation.

A knotless dynamic suture tensioning device uses a resilient mechanism to maintain tissue compression.

A surgical retractor uses interconnected blade assemblies on racks to create customizable access channels for minimally invasive procedures.

A depth stop mechanism with toothed engagement prevents over-rotation of taps and drivers, protecting thread integrity in vertebral fixation systems.

Longitudinal needle transfer between nested holders enables minimally invasive suturing in deep anatomical sites, reducing procedural time.

Segmented lock components maintain suture tension to ensure tissue stability while minimizing device complexity during percutaneous mitral repair.

Optical catheter guides instrument placement in beating heart, avoiding open surgery trauma while ensuring precise positioning.

Anchoring the septal wall with a flanged device reduces tissue stress and sharp angle navigation challenges during mitral valve access.

Catheter-based anchors rotate and tension heart walls to remodel geometry, reducing patient trauma from open surgery.

Spring-loaded drive rods limit transmitted force during circular needle rotation, resolving trade-offs between suturing speed and manual handling complexity.

Segmented core filaments inside a high-fill braided sheath resist bending deformation while allowing independent yarn movement for easy handling.

Biocompatible mesh with integrated hooks reinforces surgical incisions by distributing tensile loads across the wound site.

A silicone cover-coated stent seals damaged arterial walls to stop bleeding and restore blood flow.
