Embodiment Construction

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0034] (first method)

[0035] exist figure 1 In , reference numeral 1 denotes an endoscope to which the present invention is applied. In the present embodiment, the endoscope 1 is an ultrasonic endoscope capable of capturing ultrasonic tomographic images of predetermined observation sites in the subject by scanning an ultrasonic beam within the subject. The endoscope 1 includes an insertion unit 10 capable of being inserted into a subject, an operation unit 30 located at a proximal end of the insertion unit 10 , and a universal cable 40 extending from a side of the operation unit 30 .

[0036] The insertion part 10 is composed of a distal end part 11, a bending part 12, and a flexible tube part 13. The distal end part 11 is provided with an ultrasonic probe part 50 for transmitting and receiving ultrasonic waves and capturing ultrasonic tomographic images, and an op...

Abstract

An adjustment section (19) for raising a treatment device, the adjustment section (19) including a rising member (65) and an operating wire (66), is disposed within a front end section (11) at a position outside a treatment device delivery passage which comprises an outlet member (60) and a tube (61). As a result of this configuration, cleaning work can be performed by inserting a brush or the like into the treatment device delivery passage, and consequently, the cleaning work can be performed easily in the same manner as endoscopes of the type not having a function of raising the treatment device.

Description

technical field [0001] The present invention relates to an endoscope having a channel opening at the tip of an insertion portion. Background technique [0002] The endoscope used in the medical field can observe the internal organs by inserting the long and thin insertion part into the body, or use the treatment instrument inserted into the through channel of the treatment instrument included in the endoscope as needed Perform various treatments. [0003] According to the different types of endoscopes, there are endoscopes with a mechanism capable of changing the protruding direction of the treatment instrument. A forceps lifting mechanism that touches and can greatly change the bending angle of the tip of the treatment instrument. [0004] However, as disclosed in Patent Document 1, in order to change the protruding direction of the treatment instrument in the conventional treatment instrument lifting mechanism, bearings for lifting the treatment instrument and various ba...
