Suture Equipments TRIZ Cases
- Sheathless Anastomotic Ring Applier With Articulating Panels
Articulating panels cover the deployment mechanism during insertion and extraction, preventing tissue entrapment without a tubular sheath.
- Surgical Port Assembly Drive Members for Instrument Tilt Control
Drive members in a port assembly tilt instruments laterally, resolving precision versus complexity trade-offs in minimally invasive surgery.
- Adjustable Suture Syndesmosis Fixation for Joint Stability
Flexible suture constructs replace rigid screws to prevent hardware failure and joint stiffness while maintaining physiological mobility.
- Bioabsorbable Adhesion Barrier for Surgical Closure
Bioabsorbable envelope with rigid barrier prevents postoperative adhesions during abdominal closure, eliminating bowel injury risks from displacement.
- Deformable Suture Guide for Cardiac Wound Adaptation
A plastically deformable suture guide anchors threads in defined gaps to simplify knotting.
- Electrode Lead Anchoring via Coupling Member and Anchor
Segmented anchors deploy percutaneously to secure leads against dislodgement while maintaining precise tissue positioning.
- Suture Management Device with Cantilever Blade and Expandable Actuator
An expandable member actuates a cantilever blade within a tubular member to sever sutures in restricted access regions.
- Manual T-Shape Suture Tensioning Device for ACL Reconstruction
A manual suture tensioning device uses a T-shaped bar with orthogonal finger guard and lateral cleats to secure grafts.
- Expandable Implant Radial Expansion for Secure Tissue Fixation
An expandable implant achieves secure tissue fixation through radial expansion of a compressible sheath.
- Mucosectomy Stapler with Annular Grooves for Controlled Tissue Retraction
Annular grooves on the central rod engage tissue sutures at discrete intervals, eliminating manual pulling and ensuring homogeneous mucosa removal.
- Suture Anchor Driver Clutch Mechanism for Tension Control
A suture anchor driver clutch uses a frictional slot to hold tension during implantation.
- Pelvic Floor Repair via Vaginal Imaging Guidance
Ultrasound-guided surgical instruments advance through the vaginal wall to attach tissue repair devices directly to target anatomical landmarks.
- Medical Tube Insertion Kit with Support Rod and Barbs
A surgical kit uses a support rod to stiffen a medical tube for single-puncture insertion through tissue.
