  • Patent number: 8986196
    Abstract: A surgical instrument extends through a guide tube and exits at an intermediate position of the guide tube. The instrument includes a parallel motion mechanism that changes the position of a distal end of the surgical instrument without changing the orientation of the distal end. An image capture component is at the distal end of the guide tube, and a joint allows the image capture component to move while the intermediate position remains stationary. The configuration allows a cross section of the guide tube to be oblong. In some aspects, a joint for the image capture component is placed between exit ports for surgical instruments, which allows the guide tube cross section to be further reduced.

The side-viewing capturing optical system has a side-viewing objective lens, a prism with a half mirror surface, and a varifocal lens. Light incident on the half-mirror surface from the side-viewing objective lens is reflected to be incident on a CCD through the varifocal lens. Moving the varifocal lens allows the side-viewing capturing optical system to switch from normal observation to magnifying observation and vice versa. In the magnifying observation, a best focus position resides on an extension, of an outer circumferential surface of the distal portion, facing the cutaway portion.

  • Patent number: 8226551
    Abstract: A scanning endoscope, comprising a first transmitter, an actuator, and a mirror, is provided. The first transmitter emits a beam of radiant light from the first emission end. The actuator moves the first emission end in a direction perpendicular to an emission direction. The mirror is arranged from the first emission end to the first direction. The mirror comprises a through-part and a reflection surface. The radiant light emitted from the first emission end passes through the through-part when the first emission end is within a first circumference.

  • Patent number: 8099157
    Abstract: The present invention is directed to a scanning system that uses uniform rotary motion of an optical reflector to create reciprocal linear scanning. The system converts uniform rotation into uniform longitudinal scanning. The system thereby creates mechanical reciprocal linear scanning free of reciprocally moving mechanical parts common in conventional scanning systems. In a preferred embodiment of the invention, the scanning system is incorporated within an imaging catheter for medical scanning. The optical reflector is rotatable and includes a spiral reflecting portion. The spiral reflecting portion may be a single uniform reflecting surface or may include several reflection surfaces arranged in a spiral configuration.
