Suture Equipments TRIZ Cases

A flexible basket retrieves suture threads during arthroscopy with fewer tools and less tissue risk.

Controlled sheath thickness and core changes create tapered cords that ease loading while preserving strength and knot security.

Threaded placental tissue streamers combine mechanical support and regenerative biomolecules for minimally invasive musculoskeletal repair.

This case uses a pre-knot, sliding loop, and stop portion to improve knot quality during minimally invasive suturing.

Segmented inner bodies articulate the catheter tip for controlled cutting and grasping of delicate heart valve leaflets.

A directional clamp and knotless tension instrument apply measurable forces to align and reinforce ankle syndesmosis ligaments.

This case uses an outer tube that stays around the suture after anchor placement, shielding it during tissue debridement.

A protruding loader head and ferrule holders guide multiple sutures into small instrument cavities, reducing manual alignment difficulty.

This case uses conductive-core sutures and low-voltage Joule heating for strong welds through curved, minimally invasive access.

A cover and piston protect hyaluronic threads from contamination while enabling controlled release and precise dermal placement.

This case uses a resilient bendable member to store and release energy, improving motion transmission and stability in a compact shaft.

An asymmetric C-shaped assembly guides an arcuate needle, improving visibility and suturing accuracy for large gastrointestinal defects.

A curved bone plate uses offset screw or suture holes to align fixation, reduce ankle syndesmosis, and limit protrusion discomfort.

A circular or oblong sheath with a tensioned flexible strand supports stronger fixation and retention in ACL/PCL and meniscal repairs.

A cannula, pusher, and locking mechanism guide knotless anchors into bone holes while trapping suture without manual knots.

A flexible pusher and sheath deploy expandable, barbed tissue anchors for adjustable positioning across varying thicknesses and angles.

This case uses dual mitral clips and adjustable chord tensioning to improve leaflet coaptation and reduce mitral regurgitation.

A gastroscopic device stretches the stomach wall to create satiety without a permanent stoma.

Rotating needle indicators show device state during minimally invasive suturing.

This case combines an intravascular covering member with external retainers to maintain clamping force across varying tissue thicknesses.

This case shows how an anchoring button and actuation sled support secure buttress placement while enabling suture severing for release.

Longitudinal anchor adjustment and nested suture channels help secure the cannula body against movement in pressurized procedures.

A catheter-delivered coaptation device uses shape-memory ribbons and anchors to improve mitral sealing despite valve motion.

This case uses leaflet and ventricular anchors with a suture lock to form artificial chordae through transvascular repair.

Pre-attached needles fit with suture in an external shaft groove, supporting alignment, sliding, and stronger anchor insertion.

A cooled guide adheres to tissue, providing a stable path for rotating and advancing helicoidal members during minimally invasive surgery.

Multiple pads distribute suture force to secure tissue openings while reducing tether contact, damage, and tissue folding.

Polymer-coated filaments retain bone graft particles for sustained tissue growth.

A cantilevered flexure engages a housing recess to stop limiter removal, while the connection feature secures the depth tube.
