Surgical Manipulators TRIZ Cases
- Pantograph Expander for Cardiac Valve Access
A pantograph expander tool uses a Bowden cable to separate tissue structures via radial expansion.
- Robotic Unit for Microsurgery with XYZ Platform and Shutter
An XYZ platform moves a robotic unit along X, Y, and Z axes while slidable shutters cover the interior during motion.
- Medical Instrument Tool Head Rolling Surface Articulation
A medical instrument tool head uses convexly curved rolling surfaces to articulate relative to an elongated shaft.
- Offset Pulley Arrangement for Surgical Instrument Articulation
An offset pulley arrangement maintains drive element tension across multiple joints, reducing instrument exchange time and setup complexity.
- Magnetic Field Surgical Tool Control System
A magnetic field-based surgical system transmits motion commands from an external master assembly to a distal instrument tip without physical linkages.
- Telescoping Support Assembly for Flexible Instrument Buckling
Segmented wedges prevent buckling and deformation of flexible instruments during minimally invasive procedures.
- Robotic Catheter Control System Synchronizes Imaging and Device Movement
Integrated control system synchronizes medical imaging capture with robotic catheter actuation for precise percutaneous device positioning.
