A system and method for displaying an endoscope image in a preferred orientation. An endoscope scans a sample with spectrally encoded light by rotating imaging optics inside an endoscope guide. A processor generates an image based on light returned from the sample, and rotates the image by a first angle offset value and a second angle offset value to display the rotated image in the preferred orientation. The first offset value is an angle difference between a specific direction in which the image is to be displayed on a display and a direction in which the tip of the endoscope is oriented with respect to the imaging plane. The second offset value is an angle difference between a direction of the line of scanning light projected onto a plane perpendicular to the tip and the specific direction in which the image is to be displayed.

An endoscope treatment tool that is insertable into a channel of an endoscope includes: an insertion unit having flexibility; and a treatment unit disposed on a distal end of the insertion unit and supported so as to be rotatable about a longitudinal axis of the insertion unit. The insertion unit includes a tubular exterior member configured to come into contact with the treatment unit on a distal end side of the insertion unit, the tubular exterior member configured to be moved in a direction of the longitudinal axis of the insertion unit, an operation member penetrating through an interior of the exterior member, the operation member configured to transmit rotation about the longitudinal axis to the treatment unit, and a wire penetrating through an interior of the insertion uni, the wire having a distal end fixed to the exterior member.

An endoscope navigation system is provided that updates an anatomy model based on a live camera signal. As the endoscope advances within the patient, a camera signal, and corresponding position signal, of the endoscope, is provided and used to update the anatomy model based on identified divergences between the camera signal at a particular position and anatomy model.

The present invention relates to comprehensive systems, devices and methods for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In certain embodiments, systems, devices, and methods are provided for delivering energy to difficult to access tissue regions (e.g. peripheral lung tissues), and/or reducing the amount of undesired heat given off during energy delivery.

A medical system includes a medical instrument, at least one actuator, and a controller. The medical instrument defines a central axis and includes a steerable tip. The controller is configured to command the at least one actuator to cause active steering control of the medical instrument according to an insertion control mode after movement of the medical instrument is detected and exceeds a first threshold value in an insertion direction and to deactivate the at least one actuator to cause the steerable tip of the medical instrument to move freely, without the active steering control, in reaction to forces exerted against the medical instrument by a wall of the anatomic passageway after axial movement of the medical instrument is detected by the medical system and exceeds a second threshold value in a retraction direction. At least one of the first or second threshold values comprises a velocity threshold value.

The subject matter discloses a multi-sensor endoscope having a dynamic field of view comprising an elongated shaft terminating with a tip section; a maneuvering section connected to the elongated shaft; at least two sensors, wherein at least one sensor is placed behind the tip section, on the maneuvering section; and one or more illuminators located on external surface of the shaft. In some cases, the sensors include a camera. The subject matter also discloses a multi-sensor endoscopy system comprising an endoscope comprising a handle and a controller, such that the maneuvering section is controlled by the controller.

Disclosed herein are systems and techniques for compensating for insertion of an instrument into a working channel of another instrument in a surgical system. According to one embodiment, a method of compensation includes: detecting insertion of an insertable instrument into a working channel of a flexible instrument; detecting, based on a data signal from at least one sensor, a position change of a distal portion of the flexible instrument from an initial position: generating a control signal based on the detected position change; and adjusting a tensioning of a pull wire based on the control signal to return the distal portion to the initial position.

An ergonomic attachment system for connecting an irrigation tube or an aspiration tube to a surgical handpiece that reduces surgeon wrist fatigue due to tubing twist. The tube is connected to the handpiece through a swivel joint which allows the tube to rotate circumferentially with respect to the handpiece and self-adjust to a neutral position to relieve the twist.

An endoscope is provided to examine internal organs with front and rear views. The endoscope comprises a shaft extending from a distal end in a rearward direction along a longitudinal axis towards a proximal end, with the distal and proximal ends defining a hollow channel extended there-through. The endoscope further comprises a first lens positioned adjacent to the distal end and configured to receive a first image in a forward direction along the longitudinal axis, with the forward direction generally 180 degree from the rearward direction. The endoscope further comprises a rearview module positioned adjacent to the distal end. The rearview module comprises a second lens configured to be positioned adjacent to the distal end, and receive a second image in a target direction having a directional component in the rearward direction along the longitudinal axis, independently of the first lens receiving the first image in the forward direction.

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.
