Suture Equipments TRIZ Cases

Preplaced septal sutures enable controlled large-bore access, rapid defect closure, and future atrial crossings with less tissue damage.

A guide rod and button assembly let the sleeve move and detach from the transforaminal endoscope, improving positioning, cleaning, and disinfection.

A lockable positioning assembly adjusts the spinal endoscope’s working sleeve for compact access and easier surgical tool operation.

Catch needles engage suture needles to secure mitral flaps percutaneously, while separate catheters knot, cut, and correct misplaced sutures.

Fin-like projections in aligned rows help a surgical suture pass easily while resisting reverse tissue movement without knots.

A rotating hook and notched member grasp sutures in confined sites, limiting movement near adjacent tissues and instruments.

A coplanar eyelet-and-slot driver applies rotational force to helical tissue anchors for controlled implantation and retrieval.

Adjustable arms and a spring-biased clamp secure a heart valve leaflet for minimally invasive artificial chordae tendineae repair.

Arcuate channels guide sliding needle passers and a suture shuttle to close large defects with one endoscopic operator.

Deformable needle parts adapt during insertion to improve medical-fluid ejection while carrying the thread into muscle tissue.

Mitral annular dilation can impair leaflet coaptation; selective posterior tightening preserves the anterior annulus and reduces regurgitation.

A spring-biased clamp secures a heart valve leaflet for artificial chordae attachment, enabling transluminal repair without open-chest surgery.

Inferior-to-superior PDO insertion through deep cheek fat pads addresses ptosis while limiting disruption of superficial facial tissue.

RFID chips and needle or thread antennas enable wireless suture-needle tracking and counting despite metal-related signal interference.

Varying tissue thickness can cause staple leakage and tearing; stimuli-responsive bonding helps a bioabsorbable polymer adjust compression and strength.

Magnetic dipole alignment helps capture and retrieve sutures through a cartridge tube when indirect visualization limits positioning.

A threaded plug, movable distal tip, and anti-rotation sleeve combine broad contact with efficient tissue-to-bone fixation.

A retaining member holds small tissue anchors in a housing until sufficient proximal force enables controlled release for transcatheter delivery.

Force sensors and endoscopic imaging turn suture tension into on-screen overlays, helping surgeons avoid tissue damage and suture breakage.

Vacuum suction stabilizes damaged tissue while guided needles place sutures, enabling closure through a catheter instead of open-heart surgery.

Combines linear staples with a preloaded purse-string suture to enlarge the tissue cuff and simplify consistent bowel anastomosis.

Vibratory energy embeds fasteners in bondable materials, improving fixation while shortening retrieval and protecting surrounding tissue.

Concealed blades remain protected until the jaws close, while one instrument clamps and cuts sutures in narrow surgical fields.

An anchor sleeve and shuttle pull a sliding suture into a bone pilot hole for faster, more stable knotless tissue attachment.

A variable-width slot guides a rigid sheath and suture around bone fragments, securing alignment without added locking mechanisms.

A movable release member captures or releases opposing coupling members, enabling remote suture detachment without cutting unused lengths.

A collar-and-plug anchor maintains graft suture tension before final fixation while sealing the bone tunnel to contain biologics.

A movable arm, interference-fit mount, and cam surface guide arced needles into suturing devices while shielding both ends.

An accordion-folding suture anchor tightens inside a bone socket to deliver adjustable, knotless soft-tissue fixation.

This case addresses mitral and tricuspid valve instability with a compressible nitinol stent, tissue anchors, and catheter-based deployment.

A force-limiting element uses elastic deformation or a reversible connector to protect a treatment tool from hard-tissue contact during deployment.

A venous catheter crosses the interventricular septum to suture and anchor a flail mitral leaflet, avoiding open-heart surgery.

A toggle, plug, and suture are deployed through venous access to seal larger aortic punctures while reducing tamping force.

A needle receiver combines friction and compression sections to keep a two-part sewing needle assembled during ligament graft preparation.

Bridge-patterned sheaths and flexible strands address weak anchor retention by increasing bulk, rigidity, and pull-out strength in tissue repair.

A flexible element links tendon and bone coupling devices through a bone tunnel, improving repeatability and limiting suture migration.

A marked guide and integrated suture passer support precise, reproducible trocar wound closure without endoscopic visualization.

This case shows how notches and hardness zones control staple deformation, reducing buckling in dense rows while supporting adjunct layers.

This integrated line forms multidirectional cogs without heat or yarn rotation, then assembles, sterilizes, and packages the lifting thread.

A movable jaw and cannulated needle simplify leaflet capture and puncture for minimally invasive mitral or tricuspid repair.

This case shows how radially expandable anchors secure annular valve tissue through a catheter, avoiding open surgery and bypass.

Stereo-endoscopic imaging and biomechanical modeling generate needle trajectories that improve tissue approximation and pressure.

A cannulated suture anchor uses threaded advancement and friction capture to secure soft tissue to bone while preserving tension.

This case uses guided bone cuts, a pocket implant, screws, and sutures to align the great toe while limiting tissue damage.

A two-part release liner protects wound-closure adhesive and provides a non-adhesive grip for repositioning.

This case combines malleable and non-malleable pressure subsystems with sutures and adhesives for sustained, localized wound closure.

Movable clasp arms and actuator-driven needles place sutures across PFO septa for secure, less invasive closure.

This case combines nested tines, flexible seals, and superelastic stents for stable mitral valve deployment with less leakage.

EDS verifies coating uniformity for consistent bone bonding and healing.

A lumened tissue anchor and adjustable suture loop improve tongue suspension while reducing pull-out and infection risks.
