摘要: A tissue sensing device for use with an electrosurgical knife is proposed which comprises a proximal end portion, a distal end portion and a grip portion there between. The proximal end portion is configured for attachment to a housing of the electrosurgical knife. The distal end portion is configured for movably supporting a blade of the knife. A distal end of an optical fiber is arranged at the distal end portion of the device and a proximal end of the optical fiber is connectable to an optical console, so that optical measurements can be performed at the distal end portion.

摘要: A biopsy device with a hollow shaft is suggested, the shaft having a wall and a distal end portion, wherein a sidewardly facing notch is formed in the distal end portion. At least two optical fibers are arranged in the wall of the shaft so that end surfaces of the fibers are arranged in a longitudinal direction at opposite positions with respect to the notch.

摘要: The present invention relates to an optical fiber connector arrangement that finds application in the general field of optical interconnection. The optical fiber connector arrangement (935) comprises a first optical fiber connector (922) including a first optical fiber (905) and a counterpart optical fiber connector (923) including a counterpart optical fiber (925); wherein the first optical fiber connector (922) is configured to mate with the counterpart optical fiber connector (923). The first optical fiber (905) of the first optical fiber connector (922) has a core diameter D1 and a Numerical Aperture NA1; and the counterpart optical fiber (925) of the counterpart optical fiber connector (923) has a counterpart core diameter D2 and a counterpart Numerical Aperture NA2. At least one of the ratio (D1/D2) or the ratio (NA1/NA2) either exceeds 1.15 or is less than 0.85.

摘要: The present invention relates to a medical needle which comprises an elongate tube and at least one optical fiber, e.g. two fibers, arranged within the elongate tube, for making optical measurements at the distal end of the needle. The optical fibers(s) has a beveled distal end surface, wherein a plane touching the beveled distal end surface and a longitudinal extension axis of the optical fiber forms a bevel angle which is 30°-35°. Such needle is advantageous for providing a medical needle which is reliable and long term stable, can be manufactured in low cost using known optical fiber materials, thus allowing it to form part of disposable medical kits. Still, the bevel angle of 30°-35° provides a needle which is easy to insert and which provides a low tendency to cause tissue sticking. Especially, the elongate tube and the optical fiber end(s) have the same beveled angle within the range 30°-35°, thus allowing a smooth front surface of the needle.
