Embodiment Construction

[0029] Hereinafter, preferred embodiments of a rigid endoscope according to the present invention will be described in detail with reference to the accompanying drawings.

[0030] figure 1 is a block diagram showing an endoscope system 12 to which a rigid endoscope 10 according to an embodiment is applied.

[0031] figure 1 The endoscope system 12 shown in FIG. 2 includes a rigid endoscope 10 , a processor device 14 , a light source device 16 and a monitor 18 .

[0032] The rigid endoscope 10 includes: an endoscope main body 24 including a hand-side operation portion (operation portion) 20 to be grasped by an operator and an insertion portion 22 to be inserted into the abdominal cavity; and a casing 26, The insertion portion 22 is inserted into the housing. In operation, insertion portion 22 is inserted into housing 26, and housing 26 is inserted into a trocar (not shown) passed through the patient's abdominal wall. Therefore, the front end of the insertion portion 22 is i...

Abstract

Provided is a rigid endoscope including a fluid pipe line, in which the operability can be improved. A ferrule 50 is provided in a base end part of a hand-side operation part 20 of a rigid endoscope 10, and a leading end part of a fluid pipe line 48 is connected to the ferrule 50. In addition, a cleaning water supply apparatus including a water supply tank 70 and a CO 2 cylinder 76 is connected to a base end part of the fluid pipe line 48, and an observation window 66 and illumination windows 68, 68 are cleaned with cleaning water. Further, the axial direction of the ferrule 50 and the axial direction of a rigid part 28 of an insertion part 22 are set to be parallel to each other, preferably, the same direction, whereby the operability is enhanced. The CO 2 cylinder 76 is connected via a diverter valve 72, and the observation window 66 and the illumination windows 68, 68 are dried with a CO 2 gas. In addition, a base end pipe part 44 to be gripped by an operator and a flange part 46 are provided on the base end side of the hand-side operation part 20, to thereby prevent the fluid pipe line 48 connected to the ferrule 50 from being crushed by the operator by mistake.

Description

technical field [0001] The present invention relates to a rigid endoscope, and more particularly, to a rigid endoscope including a cleaning device that cleans an illumination window and an observation window placed on a front end face of an insertion portion with cleaning water. Background technique [0002] A rigid endoscope disclosed in Japanese Patent Application Laid-Open No. 2009-189496 as a rigid endoscope used in laparoscopic surgery includes a cleaning device that cleans the front end placed on the insertion portion with clean water. Transparent lighting windows and transparent observation windows on the surface. [0003] The cleaning device includes a water supply housing into which the insertion portion is inserted. A tubular connection portion is placed in the base end of the water supply housing, and a water supply pipe is connected to a side of the connection portion. The water supply pipe is connected to an external water supply tank, and gas is supplied to t...
