Problems solved by technology

[0008] However, in the conventional endoscope described in Patent Document 1, the front end itself is small, and since the erecting stand is accommodated in the erecting stand receiving groove (the slit for accommodating the erecting stand), the exposed portion is relatively small. In addition, the gap between the stand and the stand storage tank is narrow, so it takes time to clean with a brush, etc.

[0048]

[0049] Such as figure 1 As shown, the endoscope 10 has an insertion portion 12 inserted into the body of a subject, and an operation portion 14 is connected to the proximal end side of the insertion portion 12 . A universal cord 16 is connected to the operation unit 14 , and the endoscope 10 is connected to a light source device, an image processing device (processor) and the like, not shown, via the universal cord 16 .

[0050]

[0051] The insertion portion 12 is configured by sequentially connecting the distal end portion 12 a , the curved portion 12 b , and the flexible portion 12 c from the distal end side toward the proximal end side (operating portion 14 side). A breakage preventing member of the insertion portion 12 is provided on the most proximal end side of the soft portion 12c.

[0052]

[0053] The operation part 14 is provided with: the operation lever 20, the angle knob 18 for performing the bending operation of the bending part 12b, the stand 46...

[0092] Next, a second embodiment of the endoscope according to the present invention will be described. In addition, in 2nd Embodiment, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and detailed description is abbreviate|omitted.

[0093] The basic structure of the endoscope according to the second embodiment is the same as that of the endoscope 10 according to the first embodiment, but in the second embodiment, the structure of the tip part is different from that of the first embodiment. Figure 12 It is a figure which shows the front-end|tip part main body 71 which concerns on 2nd Embodiment (illustration of the cover 32, the stand 46, and the stand riser 42 is omitted), Figure 13 is a diagram showing the front end portion 70 of the stand 46 at the first lying position in the second embodiment (the illustration of the cover 32 is omitted; in Figure 14 the same as in ), Figure 14 It is a figure which shows the front-end|tip part 70 a...

Abstract

An endoscope which can reduce time and labor for cleaning processing is provided. According to an endoscope (10) according to an aspect of the present invention, in a cap (32), an opening window which opens an opening portion on an upper surface side of an elevator housing slit (38) a state attached to a distal end portion body and a partition wall portion which closes an opening portion on a lower surface side are formed, and in a state in which the cap is attached to the distal end portion body, reclining of an elevator (46) is regulated by the partition wall portion. Moreover, an opening portion from the upper surface to the lower surface through a front surface of the distal end portion body is extended and open, and thus, an exposed range of the elevator (46) is wide, and the elevator can be cleaned rapidly and easily.

Description

technical field [0001] The present invention relates to an endoscope, and in particular, to a structure of a distal end portion of an endoscope having a treatment instrument erecting platform and an erecting mechanism for the erecting platform. Background technique [0002] In an endoscope, various treatment instruments are inserted into a treatment instrument insertion port provided in an operation portion, and are used for treatment after being drawn out from a treatment instrument outlet opening that opens toward the distal end. For example, guide wires and imaging tubes are used in duodenoscopes, puncture needles are used in ultrasonic endoscopes, and forceps and snares are used in direct vision endoscopes and strabismus endoscopes. appliance. Since such a treatment instrument needs to change the lead-out direction at the distal end in order to treat a desired position in the subject, a treatment instrument erection mechanism (erect stand) is provided at the distal end....
