た。 A medical endoscope with an advanced camera is used to observe and photograph the affected area by inserting its body cavity insertion part into the body cavity of a patient, and generally the tip component of the insertion part includes: A cartridge storage chamber is formed to accommodate the cartridge, and the film wound inside the cartridge is transferred one frame each time it is taken by operating the hand control unit via a pulling wire inserted into the insertion section. It is configured to be withdrawn sequentially in minutes. The cartridge, which stores the film wrapped around it, is formed so that the film can be drawn out through a feeding opening provided with a pair of light-shielding members.The light-shielding members are generally made of a flocked sheet called velvettin. The sheet is pressed against both sides of the film to block external light and prevent the film inside the cartridge from being exposed to light. However,
When such flocked Betutin is used as a light shielding member, when the film is pulled out from the cartridge, the fine hairs of the flocked Betutin are detached.
It very often adheres to the film surface due to electrostatic attraction. As a result, fine hair appears in the photographic image, making it very unsightly, and the condition of the affected area, symptoms,
The drawback was that it made it difficult to judge cases.
