Minimally invasive surgical instrument having articulation immobilising structure

This is a surgical tool designed for minimally invasive procedures. It features a long shaft with a working tip that can bend and move, controlled by an internal wire. The invention includes a mechanism to lock the bending tip in a specific position. This locking mechanism uses a flexible component, like a spring, that surrounds the control wire. When this flexible component is compressed, its inner space tightens around the wire, holding it still and fixing the tip's position.

Why it matters: Filed before the significant expansion of robotic surgical platforms. The ability to precisely immobilize an articulated end effector is now highly valuable for automated surgical tasks and enhanced robotic control, which rely on stable tool positioning.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom surgical parts, precision locking mechanism
