A two-stage method for guiding an endoscope and second device toward a target destination near the ROI includes navigation and localization. The endoscope is navigated near the vicinity of the ROI according to a pre-procedure plan. When the ROI location is reached, the second device's tip is pushed far enough through the endoscope so that its tip is outside the endoscope and in the endoscope's video view. Then a two-phase registration mechanism is used: i. Phase 1: Align the endoscope by registering the endoscope's video to a virtual bronchoscope's simulated video stream; ii. Phase 2: Align the second device by registering the second device's shape in the endoscope's video to a virtual second device model.

Described herein are devices and related methods for occluding at least a portion of a body lumen during a surgical procedure. In some embodiments, the device includes an inner shaft defining a lumen therethrough and a first aperture, and an outer shaft including a flexible member and defining a lumen therethrough and a second aperture positioned on the outer shaft proximally relative to the flexible member. The inner shaft extends through the lumen of the outer shaft such that at least a portion of the outer shaft is axially translatable toward and away from a distal portion of the inner shaft. The flexible member is movable between an unexpanded configuration and an expanded configuration when at least a portion of the outer shaft is axially translated toward or away from the distal portion of the inner shaft. In some embodiments, the devices and methods are used for endoscopic surgical procedures.

A STEERABLE ARM HAVING SECTIONS THAT BEND IN DIFFERENT PLANES A steerable arm for use in endoscopic surgical procedures. The steerable arm cut from a tube of nitinol to provide flexibility and resilience by the structure into which the tube is cut. A hollow continuum tubular member of resilient material having two bending sections, each bending section having a series of spaced gaps along a side of the tubular member let the section of tubular member bend by closing up, the series gaps of each section offset angularly about the axis on different sides of the tubular member to that each section bends in a different plane. A preferred embodiment has three sections that bend in different planes.

A method of making the tubular body of a steerable arm for use in an endoscopic surgical procedure, comprising the steps of: providing a piece of metal configured into a plurality of coils defining the tubular body; inserting at least one wire into the tubular body; bending the tubular body and the wire inside; heating the bent tubular body with the wire inside; such that the tubular body and the wire memorise the bend.

A methodology is for deriving a guidance route to any selected site including an unplanned ROI site observed in a radiologic imaging view or endoscopic video view on an assisted-endoscopy system during a live surgical endoscopic procedure based on a preloaded initial procedure plan. The initial procedure plan can be updated by identifying a new site s at the unplanned ROI on one of graphical visualization tools of an image-guided endoscope system as a new examination destination and automatically computing the new navigation airway route that leads to the new examination destination.

A smoke evacuation flow regulator for use with a suction source to rapidly remove excess smoke during an endoscopic surgical procedure is described. The smoke evacuation regulator may include a body having a gas pathway and a knob assembly threadably attached to the body that is sized to completely open or completely close the gas pathway in a single revolution of the knob assembly. The head of the knob assembly may be sized and shaped to permit tactile determination of the rotational position of the knob assembly in low vision situations. The body of the smoke evacuation flow regulator may include a knob assembly retaining arm that cooperates with a disk or extension on the knob assembly to allow rotational freedom of the knob assembly, but prevent inadvertent removal of the knob assembly from the body during use.

A controller of a surgical system is configured to receive a surgical plan associated with an endoscopic surgical procedure, receive a model of an anatomical structure associated with the endoscopic surgical procedure, segment a depth image of a surface of the anatomical structure to obtain surface geometry data of the anatomical structure, register the surface geometry data of the anatomical structure to the model of the anatomical structure, and update the surgical plan according to the registered surface geometry data.

A trocar with cleaning and smoke evacuation functions is provided for use during endoscopic surgical procedures. The trocar includes a housing and an elongated shaft with channels and an access valve at the distal tip. The trocar is fitted with a multiport valve that alternates between an inlet for cleaning and an outlet for smoke filtering.

A mixed reality endoscopic surgical procedure method, including the steps of selecting a three-dimensional holographic first image of a body part to be surgically operated on and displaying the three-dimensional holographic first image of the body part. The method can further include positioning an endoscope relative to the body part, wherein the endoscope further includes a guidewire, displaying a three-dimensional second holographic image or video of the endoscope or guidewire relative to the body part, and using the three-dimensional first holographic first image as a visual guide for engaging the body part via the guidewire.

A surgical system includes a protective cover, an ultrasound device, and a surgical device. The protective cover includes a body configured to receive at least a portion of an ultrasound device through an open proximal end and into the interior volume of the body. A coupling assembly includes an inner coupler disposed within the interior volume of the body on an interior surface of the body and an outer coupler disposed on an exterior surface of the body. The inner coupler is configured to couple to the ultrasound device and the outer coupler is configured to couple to the surgical device to thereby constrain the ultrasound device and the surgical device in at least one degree of freedom while permitting movement of the surgical device relative to the ultrasound device in at least one other degree of freedom.

Provided is a puncture outfit having a cleaning function and a smoke discharge function, the puncture outfit being used during an endoscopic surgical procedure. The puncture outfit includes a housing and an elongate shaft having a channel and a passage valve at a distal tip. The puncture outfit is equipped with a multi-way valve which alternately switches between an inlet for cleaning and an outlet for smoke filtration.
