摘要:
Apparatus, systems, and methods are provided that generate in vivo maps of oxygenation measurements of biological tissue. These may include surgical instruments and stand-alone imaging systems with incorporated oxygen sensing capability. Oxygenation maps can be determined via fluorescent or phosphorescent lifetime imaging of an injectable probe with an oxygen-dependent optical response. Probe configuration and methods and apparatus of injecting the probe into the tissue are provided. Methods and apparatus for temperature compensation of temperature-dependent lifetime measurements are provided to improve oxygenation measurement accuracy. Oxygen maps may be registered with visible light images to assist in assessing tissue viability or localize anomalies in the tissue. Resulting oxygen images may be used for various applications including, but not limited to, guiding surgical procedures such as colorectal resection through use of intraoperative sensing, enhanced endoscopic imaging for identifying suspect lesions during colonoscopy, and external imaging of tissue such as assessing peripheral vascular disease.

Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

A probe coupling apparatus can be provided which can include, e.g., at least two opposing edges, one of the edges being configured to receive a tip of a probe. The exemplary apparatus can also include an orifice provided between the edges and a portion provided between the opposing edges and extending along the orifice. The portion can have a structure such that, when a force is applied to a section of the portion, a cross-sectional area of the orifice is increase, and, when the force is released, the area is decreased.

It is disclosed a probe for use through a working channel of a bronchoscope comprising a location sensor in a distal end of the probe, the location sensor usable in combination with a location system for determining a location and orientation of the probe distal end, a working channel extending axially through the probe, an optical assembly, usable to communicate visual imagery data to a monitor of an optical scope system. The optical assembly includes a sealed optic window at a distal end of the probe, a floor spaced apart from the sealed optic window, an internal sidewall surrounding the floor and extending to the sealed optic window, the sealed optic window, floor, and internal sidewall together defining a space therebetween, a plurality of light fibers terminating at the floor, and an objective lens, and a steering mechanism capable of deflecting an end of the probe.

A master - slave robotic endoscopy system includes a flexible primary endoscope probe having at least one tool channel for carrying a tendon-sheath driven robot arm and corresponding end effector, and a secondary endoscope probe channel for carrying an imaging endoscope. The imaging endoscope provides enhanced image capture range relative to a distal end of the primary endoscope probe by way of a secondary endoscope probe channel distal opening proximally offset from the primary endoscope probe distal end; a ramp structure disially carried by the primary endoscope probe; and/or one or more actuatable distal imaging endoscope regions. Robot arms can include joint primitives that enable robot arm / end effector manipulation in accordance with intended degrees of freedom. A set of quick connect / disconnect interfaces couple an actuation controller to one or more actuation assemblies insertable into the tool channel(s), where each actuation assembly includes tendon-sheath elements, a robot arm, and its corresponding end effector.
