Articulating medical instruments

This invention describes a method for using a flexible medical instrument in surgery. A doctor inserts the instrument's tip into a patient, then uses motors in a handle outside the patient to bend a specific section of the instrument. Specifically, a pitch motor in the handle drives a pulley system with pull wires to articulate the bending section, ensuring precise and equal movement between different parts of the mechanism.

Why it matters: Since 2021, advancements in miniature, high-precision motors and compact sensor feedback systems could make achieving the claimed 'substantially equal rotation' more robust and reliable within a medical instrument.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPrecision motors, custom pull-wire mechanism, medical-grade
