Blunt Dissectors TRIZ Cases
- Vibrating Surgical Dissector with Expandable Arms
Expandable arms and a vibrating string dissect tissue without sharp blades, reducing injury risk near sensitive structures.
- Ultrasonic Cutting Loop for Embedded Filter Retrieval
An ultrasonic dissector uses a vibrating wire loop to dissect embedded vena cava filters from vessel walls, minimizing pulling force and tissue trauma.
- Ultrasonic Clamp Arm Resilient Pad Retention
Resilient members bias clamp pads into slots, preventing accidental detachment while allowing pressure-based removal for cleaning.
- Hygroscopic Endoscope Excluder for Minimally Invasive Surgery
A hygroscopically expanding endoscope excluder displaces organs through moisture absorption.
- Composite Ultrasonic End Effector for Extended Wavelength
Composite ultrasonic end effectors combine ceramic cores with metal alloys to extend propagation wavelength without increasing audible sound intensity.
- Vascular Device with Dual Sharpness Arms for Occlusion Removal
Dual sharpness arms on a rotating vascular device remove occlusions while minimizing vessel wall damage.
- Rotary Catheter Drive Seal-Set Eccentricity Compensation
A rotary catheter drive seal-set uses a bearing to align a flexible shaft within concentric bores for accurate support and hydraulic sealing.
