A laparoscopic device includes a flexible insertion part including an imaging optical system and an illumination optical system that are covered with an exterior tube; and an operational part connected to a base end of the insertion part. The insertion part is inserted into a peritoneal dialysis catheter for observation of an abdominal cavity, and the insertion part includes a distal extended part that is extendable from the peritoneal dialysis catheter in the abdominal cavity during use and formed in a shape with a curved part having a cumulative central angle between 180&#xb0; and 360&#xb0;.

Laparoscopic device and endoscopic system

A lens barrel for imaging a subject; and a lens frame which holds the lens. The lens frame includes a body structure opened at a tip and an end; and a lens base which fixes the lens and is adhered to a tip opening of the body; the lens base includes: a tip base including an opening which exposes a tip side lens optical surface and an inner side which supports the lens; and a circle or arc sidewall extending axially from the tip base; the inner surface of the sidewall is formed along an outer circumference surface of the lens; the inner side surface and the outer circumference are adhered to each other; and a portion of the upper surface of the sidewall is provided toward an end side separated from the far end of the lens to be exposed inside the body.

Lens barrel, image obtaining unit, and method for assembling same

Provided is an optical connector plug of which housing is provided with: a first member that has at least a lower surface section that covers the lower side of a providing space in which an optical fiber and a ferrule are provided, a half of a back surface section from which the optical fiber is led out, and a half of a front surface section from which the ferrule is led out, and is composite-molded out of a thermoplastic resin; and a second member that has at least an upper surface section that covers the upper side of the providing space, the remaining half of the back surface section and the remaining half of the front surface section, and is composite-molded out of a thermoplastic resin into the same shape as the first member.
