摘要： An endoscope capable of being autoclaved in accordance with the present invention includes an insertion unit, an internal endoscope space, and contents. The insertion unit has a soft member, which is made of a soft polymeric material, as at least part of a casing thereof. The internal endoscope space includes the internal space of the insertion unit that is formed at a first sealing level at which the internal space is sealed in a watertight manner relative to an outside. The contents include at least one hermetically sealed unit composed of a plurality of airtight partition members and formed at a second sealing level higher than the first sealing level by joining the meeting portions of the airtight partition members using an airtight joining material. All or part of the airtight partition members is stowed in the internal endoscope space. Even when high-pressure high-temperature steam permeates through the soft member of the insertion unit which is made of a polymeric material, and invades into the internal endoscope space formed at the first sealing level, the high-pressure high-temperature steam will be hindered from invading into the hermetically sealed unit included in the contents and formed at the second sealing level.

摘要： An electric optical adapter unit that is freely detachably attached to a rigid endoscope has an optical system stowed in the center of a housing thereof. An electric circuit such as an automatic iris unit is stowed on the circumference of the optical system. Openings of a frame at both ends of the optical system are sealed hermetically with cover glasses so that the optical system can withstand autoclaving. Electric contact pins fixed in annular plug are hermetically sealed with glass hermetic seals in the back end surface of the frame. In a TV camera unit connected to the back end of the electric optical adapter unit, a CCD and the like are stowed in the center of an imaging optical system housing that is sealed hermetically. A receptacle structured to be watertight is mounted on the circumference of the imaging optical system housing. The receptacle can be freely detachably attached to the electric contact pins of the annular plug, whereby an electric signal can be transmitted.

摘要： An electrical connector having an electrical plug (102) to be plugged into an electrical receptacle (130). The electrical plug (102) includes an electrically insulative plate-like substrate and a plurality of first electrical contacts (118) formed in parallel on at least a side surface at one end of the substrate for a predetermined length from the one end. The plug further includes a shielding part (126) formed of an electrical conductor which substantially shields all of the substrate in a position nearer an end other than the one end having the electrical contacts (118). The electrical receptacle includes an electrically insulative receiving member (138) forming at least part of a recess in which the substrate of the plug is inserted. A plurality of second electrical contacts (142) are arranged in the receiving member (138) so as to contact the plurality of contacts in the plug whenever the substrate of the plug is inserted into the recess. The electrical receptacle (130) also includes a shielding electrical contact (140) formed to contact the shielding part of the electrical plug (102). The shielding electrical contact includes a liquid removing member (235) for removing liquid from the substrate during insertion into the recess. A heated air mechanism (271, 273) may be included to assist in liquid removal. The shielding may also serve the purpose of latching the plug and receptacle together and the plug may be of circular shape.

摘要： A TV camera is attached to an eyepiece unit of an endoscope and includes a solid-state imaging device. A housing of the TV camera has an outer metallic sheathing. The outer metallic sheathing is hermetically coupled via an insulating material to a metallic housing frame of an electric connector which has contact pins connected to the solid-state imaging device and which is fixed hermetically using a hermetic seal. This structure defines a hermetically enclosed space which can withstand autoclaving. A shielding sheathing layer is formed inside an insulating layer within the hermetic space in order to shield an electric circuit including the solid-state imaging device and which is located inside the shielding sheathing layer. The shielding sheathing layer is designed to communicate with the housing metallic frame of the connector that is isolated and sheathed. This structure provides measures for solving problems concerning electromagnetic compatibility (EMC).

摘要： An endoscope apparatus comprising an electrical connector which is electrically connected to an electrical device such as a CCD in an organism inserting device such as an endoscope which has an inserting section inserted into a organism. The electrical connector is connected to an electrical connector receptacle such as a control unit after the organism inserting device has been disinfected and sterilized by disinfection liquid. Processing is first performed in which the liquid remaining in the vicinity of an electrical contact of the electrical connector is removed by a liquid removing mechanism and, thereafter, electrical operation occurs. Thus, generation of a short-circuiting accident is prevented.
