Embodiment Construction

[0029] Hereinafter, an endoscope according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an electronic mirror type endoscope. FIG. 2 is a partial sectional view of the flexible tube 15 .

[0030] As shown in FIG. 1 , the endoscope is composed of an operation unit 1 and an insertion unit 2 provided at the distal end of the operation unit 1 . A base end portion of a universal cord 3 is connected to the operation unit 1 . A mirror connector 4 connected to a light source device (not shown) is provided at the tip of the universal cord 3 .

[0031]The operation unit 1 has a plurality of switches 5 . The plurality of switches 5 are, for example, a switch for recording and freezing a still image other than a video printer, a photometric switch for switching between average photometry and peak photometry, and a switch for printing out by a video printer.

[0032] Furthermore, the operation unit 1 has butt...

Abstract

An endoscope has an adhesive (20) and a heat shrinkable tube (25). The adhesive (20) is applied to a portion (S) to be repaired having occurred with use, the portion (S) being on the outer surface of a flexible tube (15) inserted into a body cavity. The heat shrinkable tube (25) is fitted, with a space in between, over and so as to be opposite the portion (S) to be repaired, to which the adhesive(20) is applied, and fixed on the outer surface of the flexible tube (15) in an intimate manner by heat shrinkage through the adhesive (20). This way the endoscope where the portion (S) to be repaired occurring with use can be repaired relatively easily and simply and a method of repairing the endoscope are provided.

Description

technical field [0001] The present invention relates to a repair method of an endoscope for coping with a case where a repair site appears on an outer skin constituting an outer surface of a flexible tube accompanying use. Background technique [0002] For example, as shown in Japanese Patent Application Laid-Open No. 1-227735 (Patent Document 1), an endoscope used in the medical field includes a grip part for being held by an operator with one hand, and a grip part for holding with the other hand. Operates and installs operation parts such as knobs and pliers channels. The base end portion of the insertion portion inserted into the patient's body cavity is connected to the operation portion. [0003] The insertion part is composed of a soft part, a curved part and a hard part at the front end. The front hard part has an air supply / water supply nozzle and a lens (objective optical system). Since the above-mentioned soft part and curved part are flexible, they are generall...
