Operating mechanism for medical device

An operating mechanism for a medical device comprising:

• a switch that controls specified functional operations;
• an air-tight unit that can accommodate the switch air-tightly;
• a moving member which is disposed inside the air-tight unit, and which moves between a position in which the switch designates an operation and a position in which the switch does not designate an operation;
• an operating member which is disposed on the outside of the air-tight unit, which can be operated by an operator, and which is disposed such that no contact is made with the moving member;
• and
• a switching-function change-over portion which switches the functional operation of the switch by varying the position of the moving member in accordance with the operation of the operating member.

An endoscopic image-pickup apparatus having an operating mechanism for a medical device, comprising:

• a scope mount which is mounted on the ocular part of an endoscope having an insertion part that is inserted into a body cavity;
• an image-pickup element which captures an optical image that is transmitted to the ocular part;
• an optical system which further transmits the optical image from the ocular part to the image-pickup element;
• a rotating ring which holds the image-pickup element such that this element can rotate with respect to the scope mount;
• a pattern concentrically constructed and disposed on the image-pickup element;
• a contact pin that electrically contacts the pattern;
• a flexible board that electrically contacts the contact pin;
• and
• a camera cable which is electrically connected to the flexible board, and is extended to the outside.
