Cannulas TRIZ Cases
- Deployable Textile Retractor for Even Tissue Pressure
A fluid-filled textile chamber expands into a stable surgical channel, distributing pressure evenly to help preserve blood supply during long operations.
- Ophthalmic Aerosol Mitigation Collar Around Irrigation Sleeves
Irrigation sleeves can release aerosolized intraocular fluids; a nested collar and pleated skirt maintain eye contact to contain them.
- Access Sheath With Dual Spiral-Slit Valves for Low-Force Sealing
Two valves with slits that twist along the axis create a fluid-tight seal around guidewires while reducing insertion forces and blood loss.
- Self-Priming Bladder Flush Pump with Double Lateral Eyes for Stone Removal
The DC pump and double lateral eyes remove bladder stones and impurities while distributing suction to limit bladder-wall vacuum.
- Tailored Light Window for Eye Surgery Tool Visibility
Low-intensity monochromatic light highlights the surgical tool and fluorescent cannula without changing room lighting or straining the surgeon’s eyes.
- Rotary Atherectomy With Crossing Balloon for Vessel Protection
An anchoring balloon stabilizes the rotary debulker while a crossing balloon navigates occlusions and helps limit vessel dissection.
- Trocar Gearbox for Disposable Minimally Invasive Surgery
An internal gearbox converts external rotation into instrument translation, helping make the trocar a simple, sterile single-use component.
