Customizing Surgical Dissectors Using 3D Printing

This patent describes a surgical tool's working tip, called an end effector, which has two jaws whose gripping features can be custom-made using 3D printing for specific surgical needs.

Surgical Tool with Flexible, Articulating, and Rotating End Effectors

This patent describes a surgical tool with a flexible tip that can bend in multiple directions and also twist, allowing surgeons to precisely control instruments like graspers and cutters inside the body.

How Surgical Tools Give Haptic Feedback Near Operation Limits

This patent describes a surgical instrument that uses a motor to move a tool, continuously tracking its position and providing a tactile vibration or haptic feedback to the surgeon as the tool approaches the end of its movement, improving precision and safety.
