Surgical Manipulators TRIZ Cases

A flexible grounding sleeve combines skin stretch and kinesthetic actuation to deliver ungrounded 6-DoF haptic guidance with high precision.

An aligned pitch-yaw manipulator lets a bendable laparoscopic end tool reach difficult sites with more intuitive, accurate control.

Motorized joints, gimbals, and a dovetail mount improve surgeon ergonomics and make robotic surgery consoles easier to relocate.

A rotatable retraction handle and quick disconnect joint help robotic surgical tools deliver stronger tissue cutting and fastening with precise control.

A mechanical decoupling mechanism adjusts cable lengths to separate pitch and yaw motion, improving surgical robot control stability.

A cable-driven knife input assembly enables precise remote blade advance and retraction in robotic surgery while preserving surgeon distance and control.

Shifting guide pulleys and adding a bearing increases wire bending radius and cuts friction, improving forceps durability and controllability.

Guide pulley orientation and ordered cable routing cut lateral friction and cable collisions, improving surgical instrument transmission efficiency.

Lead screw transmission converts motor rotation into linear wire motion, improving end tool control while containing handle complexity.

A flexible spine and rotary screw actuator expands end effector articulation while holding position under external forces in trocar-sized instruments.

A simplified roll-and-joint mechanism cuts wire paths and tension loss while enabling precise omnidirectional laparoscopic end-tool motion.

A gimbal assembly routes actuation members without pulleys or capstans, cutting part count and slack while preserving precise multi-axis control.

A pulley frame and wire unit give a surgical end tool unrestricted axial rotation and independent yaw, pitch, and roll control.

Dynamic velocity limits near the remote center of motion curb force amplification during instrument rotation and pivoting to protect tissue.

Rotationally coupled joints and offset links widen surgical instrument motion while maintaining the remote center and limiting abdominal wall forces.

A skull-fixed hexapod and pivot arm reposition the jaw precisely without complex image registration or continuous tracking.

A redundant rotation axis expands surgical tool motion around a remote center while reducing hazardous forces on the abdominal wall.

Departure and reentry region control slows or blocks slave rotation near workspace limits to preserve intuitive surgical teleoperation.

A resilient force limiter caps jaw closure force in a surgical end effector to prevent excessive tissue compression and improve cutting precision.

Pulleys and wires align hand motion with end tool pitch, yaw, and jaw actuation, improving intuitive control and reducing direction mismatch errors.

Electrode-based user presence detection filters false haptic inputs in robotic surgery, helping prevent unintended tool movement.

Concentric nested tool channels enable true bimanual neuroendoscopy without moving the endoscope against healthy brain tissue.

Flexible spine assemblies and rotary drive screws let an articulating end effector hold position while advancing the firing member through a trocar.

A pulley-compensated jaw wire path keeps overall wire length constant, enabling smooth independent pitch and yaw motion in robotic or manual surgery.

A twisted lumen stabilizes wire path length and friction during bending, improving flexible manipulator control and maneuverability.

Radiolucent end effectors use carbon-based sensors and non-metallic conductors to deliver haptic robotic surgery inside MRI and CT bores.
