[0048] figure 1 It is an overall configuration diagram showing the first embodiment of the endoscope according to the present invention.

[0049] figure 1 The illustrated endoscope 10 is an electronic endoscope used in surgery, and has an insertion portion 12 inserted into a patient's body cavity, and an operation portion 14 grasped by an operator. The insertion part 12 is provided with the front-end|tip rigid part 16-1 which accommodates the optical unit, the imaging device unit, etc. which are mentioned later. The front end rigid portion 16 - 1 is arranged inside the outer casing of the insertion portion 12 .

[0050] The universal cable 18 is connected to the operation unit 14 . An LG (Light Guide) connector 20 is provided at the tip of the universal cable 18 . The LG connector 20 is detachably connected to a light source device (not shown). As a result, illumination light can be sent from the light source device to the distal end of the insertion portion 12 via a li...

Abstract

The present invention aims to provide an endoscope and its manufacturing method enabling to reduce a diameter of the endoscope required to have airtightness and facilitate a connecting work between a cable and a connector. A first tube body and a second tube body constituting an airtight container are relatively moved to extend and contract, so that it is possible to extend cables from a proximal end part of the second tube body by contracting the container, thereby enabling a connecting work between the cables and an airtight connector. After the completion of connecting work between the cables and the airtight connector, it is possible to store an extra length of the cables in the second tube body as well as to allow the airtight connector to engage with the proximal end part of the second tube body by extending the first tube body and the second tube body.

Description

technical field [0001] The present invention relates to an endoscope and a method for manufacturing the endoscope, in particular to an endoscope requiring high airtightness and a method for manufacturing the endoscope. Background technique [0002] Endoscopes used in surgical operations or endoscopic inspections need to be sterilized in order to prevent infection among patients. In recent years, a sterilization method in which an endoscope is sterilized by using high-pressure steam in a high-pressure steam sterilizer such as an autoclave has become mainstream. [0003] Conventionally, a technique has been proposed in which the structure of the distal end portion of an endoscope housing an optical unit and an imaging device unit is an airtight structure corresponding to an autoclave (Patent Document 1). [0004] In the endoscope described in Patent Document 1, as in Patent Document 1 figure 2 As shown, a lens unit and a solid-state imaging element are arranged inside a tube...
