From 1967 onwards, the telescope system was also used in urology for cystoscopies. A miniature flash bulb, positioned near the eyepiece of the telescope, has since provided a well-lit and colour-corrected view of the bladder interior. [18] In 1969, Karl Storz, together with Harold H. Hopkins, introduced the first arthroscope with a rod-lens system.
Storz is a type of hose coupling invented by Carl August Guido Storz in 1882 and patented in Switzerland in 1890, and patented in the U.S. in 1893 [1] that connects using interlocking hooks and flanges. It was first specified in standard FEN 301-316, and has been used by German fire brigades since 1933.
For a ring assembly to grip evenly, it is important that the scope rings are circular and coaxial with the scope tube. On ring mounts that grip unevenly, the ring mount can be lapped to prevent uneven pressure when mounting. [15] One scopes made for ring mounts, it is not uncommon to get ring marks when mounting the rings.
Hose link is a 1/4-turn bayonet-mount garden hose connection, which uses an o-ring to o-ring seal. It was designed by Hoselink, Pty, Ltd., Australia, [ 24 ] and patented in 1998. [ 25 ] It is popular in Australia, with limited distribution in the UK and the US, where it is distributed by Dayco Products, Inc.
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1] The procedure is useful in the diagnosis and treatment of disorders such as kidney stones and urothelial carcinoma of the upper urinary tract. [ 1 ]
Urethral sounding is the practice of inserting objects (typically made by metal or silicone) into the urethra for sexual gratification. [1] Urethral dilatation is a urological procedure that uses probes called sounds to enlarge the inside diameter of the urethra and locate obstructions in the urethra, or as a treatment for urethral strictures.
NOTE: Some published reviews of 4/3 instead cite the (female) "outside diameter" of the lens or mount as ~50mm (and micro-4/3 as ~44mm), [23] and not the appropriate major diameter (D) ~44mm which is the camera body's female mount inside-diameter and the lens's male mount outside-diameter (micro-4/3 ~38mm).
The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric thread on the lens with a flange focal distance of 55 mm and a mating female 42mm thread on a camera adapter or other optical component.
