External forceps channel device for endoscope

The present invention was made in the light of the foregoing backgrounds, and an object thereof is to provide a forceps channel add-on device for an endoscope, provided on an outer periphery of an insertion portion of the endoscope. The forceps channel add-on device for an endoscope is an external forceps channel device for an endoscope, which is capable of providing two forceps channels or more without controlling the luminous intensity and the field of view of the endoscope, capable of extracting a substance larger than the bore diameter of the forceps channel multiple times while using the endoscope in a state of not being drawn out, without imposing a heavy burden on a patient, and also capable of performing examination after an operation as to whether complications are incurred after the evulsion, whether there is any other affected part overlooked, and so forth. An external forceps channel device for an endoscope, provided with an external forceps channel which is capable of being repeatedly inserted and extracted in a way of being guided by a guide provided on an endoscope separately and independently therefrom along an outside of an insertion portion of the endoscope while using the endoscope without drawing it out, the endoscope incorporating an air supply path, a light source, a CCD camera, and a forceps channel and including the insertion portion and an maneuvering portion, characterized in that provided is the external forceps channel capable of repeatedly extracting a foreign substance larger than a bore diameter of the incorporated forceps channel in a way of being guided by the guide along the outside of the endoscope, together with the whole external forceps channel itself in a state where the foreign substance is grasped by forceps inserted through the external forceps channel, and that provided is the external forceps channel capable of being repeatedly inserted in a way of being guided by the guide along the outside of the endoscope in a state where the endoscope is not drawn out.

Head/helmet mounted passive and active infrared imaging system with/without parallax

A passive/active infrared imaging system apparatus for mounting on a head/helmet includes a passive infrared camera Head Pack having a removable narrow band filter cover, an objective lens, a beam splitter, an uncooled focal plane array (UFPA) package, an interface board, and a display unit such a liquid crystal display (LCD), with forward/back, up/down, and tilt adjustment functions fitting any mask, mounted in the front of said head/helmet for converting infrared light images into electronic signals. An electronic unit coupled between the UFPA of the infrared camera and the display unit, includes a controller for processing video signals from the infrared camera and supplying them to the display unit. The electronic circuit includes a wireless video & audio transceiver, a piezoelectric microphone, a voice controller, and a neural network pattern recognition chip. The display unit (such as LCD)] is inside the head pack and mounted on the head/helmet for converting electronic signals into visible light images, so that it is in front of eyes of a user, so that the user can directly view an external scene without blocking his normal vision, if the optical axis of the display unit is aligned with the optical axis of the objective lens, the system parallax is eliminated. A Battery Pack having a video controller board and battery is mounted on the rear of the head/helmet so that it gives the video output and power to the infrared system. An eye-safe near infrared laser diode with corresponding optical and electronic attachments mounted on the head/helmet illuminates targets to get images through same passive infrared system.
