Abstract
An apparatus for use with an instrument includes a hub, a shaft assembly, and a navigation sensor. The hub is configured to engage a portion of the instrument, in only a predetermined angular orientation with respect to an axis of the instrument. The shaft assembly extends from the hub and defines a hollow interior and an open distal end. The hollow interior is configured to receive a tubular portion of the instrument. The navigation sensor can be disposed proximate the open distal end of the shaft assembly. The navigation sensor can be configured to generate a signal indicating a portion of at least a portion of the shaft assembly in three-dimensional space.
Claims20
A flexible adapter for use with a tissue shaving instrument, the flexible adapter comprising:
- a hub configured to engage a portion of the tissue shaving instrument, in a predetermined angular orientation with respect to an axis of the tissue shaving instrument;
- a shaft assembly extending from the hub and defining a hollow interior and an open distal end, the hollow interior being configured to receive a tubular portion of the tissue shaving instrument;
- and
- a navigation sensor being disposed proximate the open distal end of the shaft assembly, the navigation sensor being configured generate a signal indicating a position of at least a portion of the shaft assembly in three-dimensional space.
A navigation assembly for use in an ENT procedure, the navigation assembly comprising:
- a rotary instrument, the rotary instrument comprising a body, a rotary hub associated with the body, and a shaft extending from a portion of the body or the rotary hub, wherein the shaft comprises an end effector proximate a distal end of the shaft, wherein the end effector comprises a rotating feature configured to affect tissue;
- and
- an adapter, the adapter comprising:
- an adapter hub configured to receive a portion of the rotary hub at only a predetermined angular orientation about a longitudinal axis of the shaft,
- a shaft assembly extending distally from the adapter hub, the shaft assembly comprising a sleeve configured to receive the shaft of the tissue shaving instrument within a hollow interior defined by the sleeve, and
- a navigation sensor secured to a portion of the adapter and being configured to generate a signal indicating a position of one or more features of the sleeve in three-dimensional space, the navigation sensor being positionable proximate the end effector of the tissue shaving instrument when the shaft of the tissue shaving instrument is received within the sleeve of the adapter.
A method of using a tissue shaving instrument with a navigation adapter, the method comprising:
- inserting a shaft of the tissue shaving instrument into a sleeve of the navigation adapter to align an open distal end of the navigation adapter with an end effector of the shaft of the tissue shaving instrument;
- receiving a portion of the tissue shaving instrument within a portion of the navigation adapter to confirm angular alignment between a navigation sensor coupled to the sleeve of the navigation adapter and the end effector of the tissue shaving instrument;
- and
- locating the open distal end of the navigation adapter in three-dimensional space to navigate the end effector of the tissue shaving instrument using the navigation sensor coupled to the sleeve.
