Suture Equipments TRIZ Cases

Semi-rigid bars and ribbons in tissue plication anchors reduce annular circumference to restore leaflet coaptation without open heart surgery.

Relaxation and annealing steps shape polyhydroxyalkanoate filaments to reduce curling and extend strength retention in absorbable meshes.

Integrated clamping mechanism secures patella during resection and drilling, reducing surgical complexity while maintaining high precision.

A preloaded suture loop knotting element deploys through a minimally invasive device to ligate tissue without manual threading.

Temporary occlusion via expandable member limits blood loss during large bore hole closure without complex sutures.

Circular housing with detachable hair fixers positions scalp lacerations, enabling single-operator hair apposition procedures.

Interconnected suture loops minimize the distance between fixation members and tendon constructs, maximizing femoral channel placement.

An implant maintains facet joint spacing to alleviate bone-on-bone contact.

A bowed subcutaneous fixation rod connects pedicle screws to stabilize the pelvic ring through minimally invasive internal placement.

A surgical applicator engages a suture button construct to push it through tissue or bone tunnels.

Pivotable doors on the suture anchor prevent tangling and ensure easy access during soft tissue reattachment.

Inverting needle passage direction allows direct visualization of the tip, eliminating blind traversal risks that cause bladder perforation and urethral injury.

Segmenting the barb sheet from the core fiber resolves manufacturing precision and cost trade-offs while maintaining structural integrity.

Catheter measures tissue impedance and temperature to dynamically adjust RF dosage, preventing thermal damage while ensuring complete PFO closure.

Vibrational energy melts a thermoplastic suture anchor into bone walls, while a collapsible conduit protects the suture from heat damage during fixation.

Locking pin mechanism secures suture tension without knot tying, preventing relaxation and ensuring precise bone fragment placement.

Thermosensitive modular units weld via temperature gradients to control barb orientation, reducing gauge variability that plagues traditional extrusion methods.

Rod arrays enable controlled suture looping and tensioning, resolving packaging complexity by replacing vacuum systems with manual insertion.

An asymmetric stitching bead prevents re-entry into organ tissue, and an angled vacuum cap reduces injury risk to surrounding vessels.

Inserting a biocompatible solid mass into non-conjoined lumens stabilizes their geometry, resolving alignment difficulties during anastomosis.

An adjustable button and loop construct secures biologic grafts within bone tunnels using integrated fixation devices.

Magnetically active implants use electromagnets to apply variable forces for precise joint positioning and movement assistance.

A finger-mounted zip line guides a delivery device to place suture anchors in tissue without direct visualization, reducing incision size and trauma.

A linear fastening system uses a cooperating collet member and compression ring to grip a shank without rotational torque.

A prosthetic heart valve uses a releasable coupling assembly to adjust relative end positions for secure leaflet coaptation.

A suture lock pin compresses strands within a retaining sleeve to secure tissue fixation.

Hydrophilic polymers solubilize oligodynamic metal salts in hydrophobic solvent systems to create durable antimicrobial coatings.

Adjustable pedicle screws and shaped connecting members enable instrument-free compression and distraction through a minimally disruptive guide assembly.

An internal spring allows the shell to move along the suture, absorbing tissue dynamics and reducing ulcer risk in gastropexy procedures.

A medical device package stores bioactive agents in a dedicated reservoir and uses a port to permit contact material passage for on-demand activation.

A bone implant with a spherical head element and longitudinal shaft enables epiphyseal fragment pivoting and axial displacement.

Asymmetric barb arrangements prevent suture coiling while maintaining secure anchoring, reducing tissue trauma and material excess.
