In general, devices, systems, and methods for fiducial identification and tracking 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.

The present invention addresses the problem of providing a small-sized, low-cost medical optical imaging device capable of irradiating even a deep portion of a dental root canal. Provided is a medical optical imaging device (4) that is provided with an illumination unit (6) for emitting illumination light to a subject, an imaging section (7) for imaging the subject, and a controller (8) for controlling at least the imaging section (7). The imaging section (7) is provided with an imaging lens system (71) and an imaging element (72) for receiving an optical image created by the imaging lens system (71). When viewed from the subject side, the illumination unit (6) is disposed in front of the imaging lens system (71) and overlapping the imaging lens system (71).

In an endoscope apparatus including a processor, the processor specifies the position of a specific region and sets a reference scale in a picked-up image that is obtained from the image pickup of a subject on which the specific region formed by auxiliary measurement light is formed. Then, the processor extracts a region of interest, determines a measurement portion, calculates a measured value obtained from the measurement of the measurement portion, on the basis of the reference scale, and generates a measured value marker using the measured value. Further, the processor creates a specific image in which the measured value marker is superimposed on the picked-up image.

A surgical suturing tracking system is disclosed. The surgical suturing tracking system is configured to detect and guide a suturing needle during a surgical suturing procedure. The surgical suturing track system comprises a control circuit configured to predict a path of a needle suturing stroke after receiving an input from a clinician, detect an embedded tissue structure, and assess proximity of the predicted path and the detected embedded tissue structure.

Surgical sealing ports for use with surgical instruments for access of a natural body orifice are provided. In one exemplary embodiment, a surgical sealing port includes a seal housing and at least one retention element. The seal housing is configured to be at least partially disposed within a natural body orifice and defining a plurality of ports. The plurality of ports includes at least one first port configured to control the ingress and egress of fluid between an interior volume of the natural body orifice and an ambient environment, and at least one second port that is configured to form a seal around an instrument inserted therethrough. The at least one retention element is arranged on an exterior surface of the housing and configured to affix the housing to the natural body orifice. Methods for using the same are also provided.

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

A balloon is attachably and detachably mounted on an insertion part of an endoscope. A distal end part provided at a distal end of the insertion part includes an image pickup optical system, an illumination optical system, and a beam light-emitting unit. A subject is irradiated with measurement light by the beam light-emitting unit. It is possible to recognize the position of a spot from a subject image, and to measure an observation distance to an object to be observed, the size of the object to be observed, and the like.

A method for enhanced surgical navigation, and a system performing the method and displaying graphical user interfaces associated with the method. A 3D spatial map of a surgical site is generated using a 3D endoscope including a camera source and an IR scan source. The method includes detecting a needle tip protruding from an anatomy and determining a needle protrusion distance corresponding to a distance between the needle tip and a surface of the anatomy using the 3D spatial map. A position of a surgical tool in the 3D spatial map is detected and a determination is made by the system indicative of whether the needle protrusion distance is sufficient for grasping by the surgical tool. A warning is generated when it is determined that the needle protrusion distance is not sufficient for grasping by the surgical tool.

A surgical visualization system may capture images of an interior of a cavity of a patient with a plurality of cameras. Those images may subsequently be used to create a three dimensional point cloud representing the interior of the cavity of the patient. This point cloud may then be used as a basis for displaying a representation of the interior of the cavity of the patient, which representation may be manipulated or viewed from different perspectives without necessarily requiring movement of any physical camera.
