Cannulas TRIZ Cases
- Disposable Capsule with Venturi Suction Channel for Nebulizer Recovery
Segmenting the nebulization chamber into a disposable capsule eliminates complex cleaning while a Venturi nozzle recovers unused substance.
- Irrigation Pump System for Kidney Stone Lithotripsy
Pressure-controlled irrigation and suction systems maintain safe intrarenal pressures while clearing stone fragments to prevent kidney damage.
- Medical Coupling Socket Axial Notching Mechanism
Axial coupling socket uses spring washer and notching hooks to secure medical instruments, eliminating manual rotation complexity.
- Lateral Spinal Access Assembly Minimizing Tissue Trauma
A lateral access assembly uses nested dilators to guide surgical tools through a small incision for minimally invasive spine procedures.
- Anatomical Spinal Retractor with Conforming Mounting Pad
A segmented surgical retractor uses an anatomically shaped distal end to retract tissue while a conforming mounting pad anchors the device.
- Automated Instrument Replacement Apparatus for Minimally Invasive Surgery
Automated apparatus with selection unit and guide element replaces instruments remotely, reducing procedure time and radiation exposure.
- Surgical Outer Tube With Interlocked Endoscope And Tool Slider
A surgical outer tube uses a movable slider to hold an endoscope and treatment tool in interlocked axial movement.
- Tail Vein Injection System with 6-DOF Position Adjuster
A tail vein injection system calculates three-dimensional positions of the target vessel and adjusts a syringe needle posture for precise puncture.
- Image-Guided Joint Resurfacing with Selective Material Deposition
An applicator deposits polymers or ceramics onto a joint surface guided by pre-mapped geometry to restore anatomical shape.
- Orthogonal Vessel Cutting Blades for Precise Arteriotomies
Two coordinated cutting blades create consistent slit lengths in coronary arteries, reducing vessel wall damage during beating heart surgery.
- Nested Catheter for Single-Entry Brain Fluid Exchange
A nested catheter system injects high-oxygen solutions and discharges cerebrospinal fluid through a single puncture site.
- Cranial Access System Precision Drill Stop and Single-Hole Catheter Guide
A cranial access system with a precision drill stop and catheter guide orients the drill hole perpendicular to the skull for accurate probe placement.
- Arthroscopic Cannula Seal Shield for Instrument Damage Protection
Elastomeric seal shield protects cannula seals from sharp instrument damage while maintaining fluid management.
- Positive-Pressure Double-Nozzle Nasal Cleaner With Pressure Relief
An automatic pressure relief mechanism stabilizes airflow, preventing ear canal damage from strong impact water flow.
