Excision Instruments TRIZ Cases
- Tissue Excision Cable Assembly for Precise Low-Thermal Biopsy
A resistively heated pursing cable confines current to tissue contact, enabling intact excision with less thermal injury and discomfort.
- Heated Pursing Cable Excision for Intact Minimally Invasive Biopsy
A resistively heated pursing cable cuts only at tissue contact points, enabling intact biopsy excision with less thermal damage and trauma.
- Rotary Grinding Drive Sleeve With Auto-Locking Cooling Valve
A heat-deformable communication valve stops shaft rotation when cooling flow fails, helping rotary grinding tools avoid vessel overheating.
- Rollable Inner-Layer Drive Shaft for Guidewire Friction Reduction
A rollable inner layer turns shaft-guidewire contact into rolling friction, reducing wear, melting, and uncoiling while preserving burr drive.
- Rollable Drive Shaft Structure for Guidewire Friction Reduction
A rollable inner layer turns sliding contact into rolling friction, protecting guidewires during high-speed atherectomy and lowering procedure cost.
