Diagnostic Markers TRIZ Cases
- Ferromagnetic Marker Geometry for Low-Artefact MRI Guidance
Segmented high-aspect-ratio ferromagnetic markers preserve surgical sensing while keeping MRI artefacts small enough for tumour size assessment.
- Implantable Magnetic Marker Geometry for Low-MRI-Artefact Guidance
Thin high-aspect-ratio ferromagnetic markers cut MRI artefacts while preserving 50-80 mm surgical detection and needle deployment.
- Endoscopic Locator Beacon Anchoring for Stable Target Site Positioning
An anchored beacon stays at the intestinal target site after delivery withdrawal, enabling accurate endoscopic localization for anastomosis.
- PCL Drill Guide Arm With Shielded Tip for Secure Bone Seating
An angled PCL drill guide arm uses an indicator and widened shield tip to seat on bone securely, guide tunnel placement, and protect nearby tissue.
- Marker Fastening Assembly for Stable Surgical Frame Positioning
Direct locking between the holder and frame simplifies marker assembly while keeping surgical navigation frames stable and angle-controlled.
- GI Tissue Occluder Frame for Sealing Defects Without Stricture
A segmented occluder frame seals GI tissue defects by conforming to irregular surfaces while avoiding lumen stricture and migration.
- Electroporation Catheter Balloon Markings for Fluoroscopic Orientation
Radiopaque balloon markings reveal catheter pitch, roll, yaw, and position under fluoroscopy without added circuitry or contrast agents.
- RF Guidewire Sheath Mechanism to Limit Adjacent Tissue Damage
A movable insulation sheath covers the RF guidewire electrode during advancement and retracts for piercing, reducing cross-back tissue damage.
- Electroporation Catheter Balloon Markings for Orientation Imaging
Radiopaque balloon markings let an electroporation catheter's position and orientation be read by fluoroscopy or ultrasound without extra circuitry.
- Surgical Robot Tool Sleeve Support for Load-Stable Chuck Retention
A threaded sleeve support on the robot holder diverts load from the chuck, reducing deformation, easing tool changes, and improving stability.
- Implantable Impedance Marker Detection Using Light-Switched Antennas
Light pulses switch an implanted marker antenna, letting synchronized impedance signals confirm lesion location and marker function during surgery.
- Adjustable Clavicle Hook Plate Gauge for Faster Surgical Sizing
An adjustable sizing gauge lets surgeons set hook depth and plate length in one insertion, avoiding template changes and speeding clavicle plate selection.
