摘要:
An endoscope (100) or other endoscopic instrument (100) is provided with multiple image sensors (214, 216, 218) incorporated into the distal tip (105, 106), each capturing a portion of the image provided from an optical imaging system (205). The output from the multiple sensors (214, 216, 218) is combined and manipulated into a single high resolution image (215) which can then be displayed to the user. A virtual horizon rotation feature is also provided which can rotate a displayed image within a combined field of view including data from the multiple image sensors. Various light directing element designs (212, 213, 222, 224, 402) are provided to direct image light to the multiple sensors (214, 216, 218).

Es wird eine Linse für ein distales Ende eines Optikkanals eines Endoskopschaftes bereitgestellt, wobei die Linse (7) eine Außenseite (25) und eine Innenseite (26) sowie eine die beiden Seiten (25, 26) verbindende Umfangsfläche (27) aufweist, wobei auf der Umfangsfläche (27) und einem daran anschließenden Bereich (29) der Innenseite (26) eine lichtabsorbierende Beschichtung (30) aufgebracht ist, und wobei auf der lichtabsorbierenden Beschichtung (30) im Bereich der Umfangsfläche (27) eine lötbare Schicht (31) aufgebracht ist, so dass die Linse (7) im distalen Ende (11) so einlötbar ist, dass das distale Ende (11) abgedichtet ist.
摘要:
The invention relates to an optical system (60), a stereo-video endoscope (2) as well as a method for producing an optical system (60). The optical system (60) comprises a distal optical assembly (16) and a proximal optical assembly (18), between which a prism unit (46) is arranged. The prism unit (46) is designed to supply a left beam path exiting from the exit lens (32) of the distal optical assembly (16) to the left lens system channel (38L) of the proximal optical assembly (18). Likewise, the prism unit (46) is designed to supply a right beam path exiting from the exit lens (32) of the distal optical assembly (16) to the right lens system channel (38R) of the proximal optical assembly (18). A determined second distance (D2) can be adjusted in a direction perpendicular to an optical axis (LoA, RoA) of the left and right lens system channel (38L, 38R).
摘要:
A panning stereo endoscope which maintains an up-down orientation as the stereo endoscope pans an operative field, the panning stereo endoscope including a shaft having an axis; first and second optical channels extending along the shaft, each of the first and second optical channels having an off-axis direction of view; and an actuating mechanism carried by the shaft and adapted to (i) synchronously rotate the first and second optical channels about their respective axes, and (ii) synchronously, inversely piston the first and second optical channels along their respective axes.

A tip section (1000) of a multi-camera endoscope is provided, the tip section comprising: a front looking camera (1116) and a front discrete illuminator (1240a, 1240b, 1240c) to illuminate the Field Of View (FOV) of said front looking camera. The tip section further comprises a right side looking camera (1220a) and a right discrete illuminator to illuminate the FOV of said right side looking camera, and a left side looking camera (1220b) and a left discrete illuminator (1250a, 1250b) to illuminate the FOV of said left side looking camera. A multi component cover is configured to cover and seal said tip section such as to prevent entry of fluids from the environment of said endoscope to inner parts of said tip section. The multi component cover (1010) comprises a distal component (1050) configured to cover a distal part of said tip section, and a proximal component (1030) configured to cover a proximal part of said tip section, wherein said distal component and said proximal component are configured to abut to cover said tip section.
摘要:
The invention relates to an endoscope comprising an endoscope optical unit (10) with an outer tube (12) and a fiber tube (11) which contains an optical system with an objective (22). A window (16) is provided in the end surface (14) at the end region of the outer tube (12), and the objective (22) is aligned in a slanted manner at an angle relative to the longitudinal central axis (13) of the fiber tube (11) so as to point downwards through the window (16). A fiber bundle (17) is arranged above the objective (22) in order to illuminate the region in front of the objective (22). The endscope optical unit (10) or the endoscope is characterized in that the distal end region (18) of the fiber bundle (17) is arranged in the fiber tube (11) in a distal opening (27) surrounded by the material of the fiber tube.
摘要:
Systems and methods are provided for injecting one or more agents into tissue within a patient's body that includes a catheter. A needle guide extends from a distal end of the catheter and terminates at a distal tip, e.g., including a foot with an atraumatic contact surface, the needle guide having a cross-section smaller than the distal end and being biased to a curved shape. The needle guide includes a passage communicating from a lumen of the catheter to an outlet at the distal tip, and a needle device is disposed within the passage that may be deployed from the outlet to inject one or more agents into tissue. The catheter also includes an imaging assembly on the distal end configured to acquire images of tissue adjacent the needle guide distal tip.
