Abstract
A hybrid vision device is provided. The hybrid vision device comprises: an articulating elongate member comprising a proximal end and a distal end, and a positional sensor is located at the distal end of the articulating elongate member; and a multimodal sensing probe removably coupled to the articulating elongate member, and the multimodal sensing probe comprises an ultrasound transducer and a camera located at a distal portion of the multimodal sensing probe.
Core Innovation
The invention provides a lung-bronchoscopy hybrid vision system that combines an articulatable elongate member with a distal positional sensor and a removably coupled multimodal sensing probe. The articulatable elongate member has a proximal end and a distal end and includes lumens that receive the multimodal sensing probe and an instrument. The distal positional sensor supports navigation and registration while the multimodal sensing probe provides direct visualization and ultrasound side view information.
The multimodal sensing probe is removably coupled to the articulatable elongate member through a first lumen and is extendable over a port at the distal end. The multimodal sensing probe includes an ultrasound transducer and a camera located at a distal portion of the probe. The camera provides a camera view and the ultrasound transducer provides a side view oblique to the camera view to capture movement of the instrument as the instrument is extended.
A locking interlock feature locks a position of the multimodal sensing probe relative to the articulatable elongate member upon the probe being extended over a port at the distal end. The system integrates EM tracking with the camera and ultrasound so that lesions outside an airway view can be identified and tracked using ultrasound lesion information in an overlay with EM-tracked catheter position and a CT-derived virtual airway model.
Claims Coverage
The document provides one independent claim (clm-00001). The independent claim includes four inventive features centered on the combination of an articulatable elongate member with a removable, extendable multimodal sensing probe that combines camera and oblique side-view ultrasound, supported by a distal positional sensor and an interlock that prevents axial and rotational movement between the probe and the elongate member.
Articulatable elongate member with distal positional sensor and dual lumens
An articulatable elongate member comprising a proximal end and a distal end, a first positional sensor located at the distal end, and the articulatable elongate member including a first lumen receiving a multimodal sensing probe and a second lumen receiving an instrument.
Removably coupled and extendable multimodal sensing probe
A multimodal sensing probe removably coupled to the articulatable elongate member through the first lumen and extendable over a port of the first lumen at the distal end of the articulatable elongate member.
Camera view with side-view oblique ultrasound to capture instrument movement
The multimodal sensing probe comprising an ultrasound transducer and a camera located at a distal portion, wherein the camera provides a camera view and the ultrasound transducer provides a side view oblique to the camera view thereby capturing a movement of the instrument when the instrument is extended over a port of the second lumen.
Interlock feature locking probe position relative to elongate member
An interlock feature configured to lock a position of the multimodal sensing probe relative to the articulatable elongate member upon the multimodal sensing probe being extended over the port at the distal end at a desired angular location or length location thereby preventing an axial movement or a rotational movement between the multimodal sensing probe and the articulatable elongate member.
Across the independent claim and its cited dependent refinements, the invention is directed to a hybrid vision device architecture in which an articulatable elongate member with a distal positional sensor carries a removable, extendable multimodal sensing probe. The probe provides both a camera view and an oblique side-view ultrasound to capture instrument movement during extension, and an interlock locks the probe position to prevent axial and rotational movement relative to the elongate member.
