Suture Equipments TRIZ Cases

Segmented anchor inserter uses a resilient driving tip to bend off-axis, preventing tool rupture during insertion.

Inverting anchors with elliptical tines secure stents inside a body lumen while preventing sharp distal ends from damaging surrounding tissue.

A coiled tamping device transforms into a stiff configuration to drive a sealing plug during vascular closure.

A surgical guidance system matches simulated anchor models to topographic images for precise positioning.

Nested catheter system delivers artificial chordae tendineae via clamp and anchor mechanisms, reducing surgical risk by avoiding open chest procedures.

A suturing capsule captures tissue while a needle places stitches. A catch mechanism retains and releases the suture tag along a longitudinal pathway.

A tissue anchor crossbar receives a suture to enable independent tensioning of multiple anchors.

Segmented and nested design enables the device to close large endoscopic wounds through narrow channels, reducing infection risk.

A protective sheath covers the deployment mechanism of an anastomotic ring applier during insertion.

A tension sustaining fixture uses a rotatable closure mechanism to maintain precise suture force during medical procedures.

A band implant compresses the prostate median lobe to relieve urinary obstruction.

Telescoping guide tubes stabilize a self-expandable implant in the left atrial appendage, resolving bias and migration risks during percutaneous delivery.

A sacrificial filament breaks at a threshold force to provide sensory feedback during tissue repair.

A buffered aqueous composition uses cross-linked microspheres and a pH indicator to detect pancreatic fluid leakage.

Segmented components allow the bone fastener to adapt to complex spinal anatomy, improving alignment precision without increasing device complexity.

A braided suture anchor expands radially upon tensioning to resolve laxity and micro-motion in bone repairs.

A silicone sheath covers repaired tendon ends, enabling smooth gliding through pulleys while preventing damage from fibrous edges.

Actuated internal arm secures sutures while nested tube prevents tissue trauma.

Ultrasonic welding assembly joins thread sections to form a teardrop-shaped loop with a tapered end.

A percutaneous fastening mechanism secures a valve leaflet to adjacent cardiac structures.

A wound closure device with a pivotable inner member guides a suture passer through tissue to deploy sutures on opposite sides of the opening.

Pre-stretching ultra-high molecular weight polyethylene fibers reduces gap expansion in relaxed states, preventing accelerated tissue degradation.

Movable arms pivot needle guides to direct needles at varying angles, accommodating different aperture sizes without fixed positioning constraints.

Self-locking adjustable flexible members tension ACL grafts within femoral tunnels to resolve instability risks and degenerative arthritis.

Electrospun polymer fiber patches scaffold cell migration to strengthen the bone-soft tissue interface and reduce re-rupture risk.

Molded barbs on raw yarn stretch to adjust angle, preventing detachment while maintaining tensile strength.

Handheld suturing device with needle gripper and suture assembly prevents accidental needle stick injuries to healthcare workers.

A dual needle tissue penetrating device with a flexible outer needle and inner lumen enables minimally invasive access to heart walls.

A surgical threading device sequentially ejects needle caps or sleeves to automate tissue suturing.

Surgical staple strips feature varying hardness zones in crown and leg portions to control staple formation dynamics.

A knotless suture construct uses a repair tape finger trap to capture the suture end and form a cinching loop for secure tissue repair.

Flexible stabilization bands anchor vertebrae to correct joint alignment while preserving natural spinal motion.

Discrete suture holes in the pulse generator housing anchor the device to tissue, preventing movement and reducing inflammation during nerve stimulation.
