Surgical Manipulators TRIZ Cases
- Surgical Instrument Pulley-Cable Transmission for Large-Force Actuation
Learn how non-parallel pulleys and a flexible cable transmit large forces with lower friction for reliable end-effector actuation.
- Instrument Shaft Relief Features for Bending Flexibility and Axial Stiffness
Interlocking flexural members balance shaft bending flexibility with axial stiffness and reduced rotational backlash.
- Surgical Firing Beam Arm for Cam-Driven Staple Actuation
This case shows how segmented actuation and rotatable cams support robotic dexterity while transmitting staple-forming force.
- Insertion-Coupled Surgical Instruments With Differential Wrist Articulation
A differential gear train couples shaft insertion with wrist motion for easier surgical control.
- Robotic Surgical Wrist Assemblies Using Differential Cable Drives
Differential gears improve pitch-yaw precision while reducing articulation cable stress.
- Cord-Driven Surgical Forceps for Independent Joint Control
Separate cords transmit force to bending and grasping joints, simplifying control compared with cumbersome geared mechanisms.
- Robotic Surgical Context Haptics for Boundary-Constrained Guidance
Position tracking and stiffness-based haptics guide instruments within surgical boundaries for accurate planes and implant pilot holes.
- Surgical Robot Cable Vibration Monitoring for Failure Prediction
Sensors compare cable vibration signatures with baseline thresholds to alert clinicians before surgical robot cable failure.
- Magnetic tPA Nanorobots for Targeted Clot Recanalization
A magnetic core and tPA-coated mesoporous shell enable targeted thrombolysis while limiting drug diffusion and vessel rupture risk.
- Robotic Surgical Tool Exchange Bases for Faster Procedures
Opposed exchange bases and pulley elements let surgeons replace tools without changing the robot arm, reducing time and waste.
- Surgical Adapter Worm Gear Assembly for Rotary-to-Linear Actuation
An integrated worm gear and pulley adapter simplifies rotary-to-linear end-effector actuation and cable tensioning.
