10736559 · 2020-08-11 · ·

A method and apparatus for estimating or measuring a physical area or physical volume of an object of interest in one or more images captured using an endoscope are disclosed. According to the present method, one or more structured-light images and one or more regular images captured using an imaging apparatus are received. An object of interest in the regular images is determined. Distance information associated with the object of interest with respect to the imaging apparatus is derived from the structured-light images. The physical area size or physical volume size of the object of interest is determined based on the regular images and the distance information. The imaging apparatus can be a capsule endoscope or an insertion endoscope.

Systems and methods for generating surgical summary footage are disclosed. A system may include at least one processor configured to implement a method including accessing particular surgical footage containing a first group of frames associated with at least one intraoperative surgical event and a second group of frames not associated with surgical activity. The method may include accessing historical data based on historical surgical footage of prior surgical procedures, wherein the historical data includes information that distinguishes portions of surgical footage into frames associated with intraoperative surgical events and frames not associated with surgical activity. The method may include distinguishing in the particular surgical footage the first group from the second group based on the information and, upon request of a user, presenting to the user an aggregate of the first group of the particular surgical footage while omitting presentation to the user of the second group.

Device providing safe access to a confined space, notably a lateral-access confined space

The invention relates to a device (10) for safe access to a confined space, comprising: a rectilinear support strut (12), two arms (14, 16) each fixed rigidly to an end (12a) of the strut, at right angles thereto and in opposite directions. A first arm (14) comprises at least one anchoring element (18), the second arm (16) being provided with at least two pulleys (20, 22) whose axis of rotation is at right angles to the plane defined by the strut and the arms. The anchoring element (18) and the two pulleys (20, 22) are arranged so as to allow the passage of a cordage of the anchoring element to the pulleys without interfering with the strut and the first and second arms. The strut (12) has at least one fixing member intended to cooperate with an opening (84) of the confined space in order to ensure the fixing thereof.

An imaging device includes an image sensor, an optical system forming an image of an object on the image sensor, and a processor. The optical system switches between a first state of capturing an image of the object with a single pupil and a second state of capturing an image of the object with two pupils. The processor generates a simulative phase difference image from a first captured image captured with the image sensor in the first state, and executes matching processing of comparing the simulative phase difference image with a second capture image captured with the image sensor in the second state to detect a phase difference between an image formed with one of the two pupils and an image formed with another one of the two pupils.
