A shielded intubation guide for use in an endotracheal intubation procedure, the shielded intubation guide including: an elongate body defining a passageway extending between a proximal opening and a distal opening for receiving a blade portion of an intubation device, the shielded intubation guide being configured for insertion into a mouth of the subject so that the proximal opening is positioned proximate to the mouth and the distal opening is positioned in an airway of the subject; and a shield around the proximal opening for substantially reducing emissions from the mouth, the shielded intubation guide allowing endotracheal intubation to be performed by: inserting the blade portion of the intubation device into the passageway; positioning a distal end of the blade portion proximate to the larynx of the subject; and advancing an endotracheal tube along the blade portion through the passageway into a trachea of the subject.

A medical support arm includes: a support arm that supports an endoscope; an actuator that drives the support arm; a measurement unit that measures a load applied to the actuator; a generation unit that generates three-dimensional information in a body into which the endoscope is inserted; and a correction unit that corrects the three-dimensional information on a basis of the measured load.

A delivery device may comprise a sheath configured to be inserted into a body lumen of a patient. The sheath may have a proximal end, a distal end, a first channel extending within the sheath from the proximal end to the distal end, and a second channel extending within the sheath from the proximal end to the distal end. A collective cross-sectional area of the first channel and the second channel may be more than 50% of a total cross sectional area of the sheath. The device may also be comprised of a handle at the proximal end of the sheath, wherein the handle is configured to provide fluid communication between a first port and the first channel and a second port and the second channel.

An illuminating ring assembly is disclosed. The illuminating ring configured to be used with a surgical access element. The illuminating ring assembly comprises a housing defined by a cover and a wall member extending from the cover, wherein the cover and wall member cooperate to define a cavity therein, a light element configured to be disposed with the cavity, and an attachment mechanism configured to selectively attach the housing to a surgical access element. Wherein the cover and the light element both include an opening therethrough.

An extremely small diameter endoscope includes comprises: an endoscope body having a distal end nozzle; an imaging unit disposed in the endoscope body and adapted for capturing an image; an endoscope insertion part having a proximal end portion and a projection end portion, the proximal end portion connected to the imaging unit, the endoscope insertion part passing through the distal end nozzle, the projection end portion to be positioned in a root canal of a tooth or in a periodontal pocket; and endoscope insertion part insertion means adapted for inserting the endoscope insertion part into an observation portion in the root canal of the tooth or in the periodontal pocket with an end portion of the distal end nozzle kept abutted against a surrounding portion of the observation portion.

An insertion assist system includes a guide member and a shift member. The guide member brings an outside bend of a peripheral surface of an insertion body into contact with a guide surface of the guide member. The shift member shifts a direction of the distal end of the insertion body. The shift member comes into contact with an inside bend of the peripheral surface of the insertion body when the insertion body is bent. The shift member bends the insertion body toward the guide surface about the guide surface as a fulcrum when the shift member comes into contact with the inside bend and bends the insertion body.

A surgical visualization feedback system is disclosed. The surgical visualization feedback system comprises an emitter assembly configured to emit electromagnetic radiation toward an anatomical structure. The emitter assembly comprises a structured light emitter configured to emit a structured light pattern on a surface of the anatomical structure and a spectral light emitter configured to emit spectral light capable of penetrating the anatomical structure. The surgical visualization feedback system further comprises a waveform sensor assembly configured to detect reflected electromagnetic radiation corresponding to the emitted electromagnetic radiation and a control circuit in signal communication with the waveform sensor assembly. The control circuit is configured to receive an input corresponding to a selected surgical procedure, determine an identity of a targeted structure within the anatomical structure based on the selected surgical procedure and the reflected electromagnetic radiation, and confirm the determined identity of the targeted structure through a user input.

Surgical systems are provided. In one exemplary embodiment, a surgical system includes a first scope device having a first portion within an extraluminal space and a second portion positioned within an intraluminal space. The first scope device transmits image data of a first scene. A second scope device is disposed within the extraluminal space and transmits image data of a second scene. The first portion of the first instrument is present within the field of view of the second scope device to track the first scope device relative to the second scope device. A controller receives the transmitted image data of the first and second scenes, to determine a relative distance from the first scope device to the second scope device within the extraluminal space, and to provide a merged image. At least one of the first and second scope device in the merged image is a representative depiction thereof.

In general, devices, systems, and methods for multi-source imaging are provided.

Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.
