本考案はたとえばカテーテルや鉗子などの処置
具を誘導する処置具誘導子を備えた内視鏡に関す
る。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an endoscope equipped with a treatment instrument guide for guiding a treatment instrument such as a catheter or forceps.
内視鏡の処置具挿通用チヤンネルに挿通したカ
テーテルや鉗子などの処置具の先端を体腔内の所

処置具誘導子が設けられている。処置具を体腔内
に導入する場合、処置具誘導子を起上させないま
ま処置具を差し込むと、その処置具が視野外に突

必要かつ無意識的に突き出し、知らないうちに体
腔壁を傷付けたりする危険がある。
In order to guide the tip of a treatment tool such as a catheter or forceps inserted through the treatment tool insertion channel of the endoscope to a desired site within the body cavity, a treatment tool guide is provided in the tip component of the endoscope. . When introducing a treatment instrument into a body cavity, if the treatment instrument is inserted without raising the treatment instrument guide, the treatment instrument will protrude out of the field of view, causing unnecessary and unconscious intrusion into the body cavity from the tip component of the endoscope. There is a danger that it will stick out and injure the body cavity wall without you knowing.
そこで、処置具誘導子を起上させてから処置具
を差し込むことによりその処置具誘導子に当てて
から意識的に必要な量だけ突き出すようにしてい
る。 Therefore, the treatment instrument is raised up, the treatment instrument is inserted, the treatment instrument is brought into contact with the treatment instrument guide, and then the treatment instrument is intentionally pushed out by the necessary amount.
しかし、処置具誘導子を操作するワイヤが切れ
ていたり伸びきつていたりした場合には起上操作
ノブの操作感覚だけでは起上状態がよくわから
ず、やはり体腔壁を傷付けてしまうことがあつ
た。また、特に術者は視野をのぞいて病変部をみ
つけたとき意識を視野内に集中しているので、処
置具誘導子の状態を振り返ることなしにすぐ処置
具を挿通してしまいがちであり、同様の危険が発
生しやすかつた。 However, if the wire that operates the treatment instrument guide is broken or stretched, the raising state cannot be clearly determined just by the feeling of operating the raising control knob, which may result in damage to the body cavity wall. . In addition, especially when the surgeon looks into the field of view and finds a lesion, his or her attention is focused within the field of view, so there is a tendency to immediately insert the treatment instrument without looking back at the condition of the treatment instrument guide. Similar dangers were likely to occur.
さらに、その処置具誘導子がどの程度起上して
いるか実際のところはわからないため、たとえば
処置具誘導子が最大に起上しているにも拘らず、
念のため起上させるのが普通であり、このため、
操作用ワイヤに無理な張力がかかり、そのワイヤ
が伸びてしまうという不具合があつた。 Furthermore, since it is not known how much the treatment instrument guide is actually raised, for example, even though the treatment instrument guide is raised to the maximum,
It is normal to raise it just in case, and for this reason,
There was a problem in which unreasonable tension was applied to the operating wire, causing the wire to stretch.
また、処置具には曲げの抵抗があり、このため
処置具誘導子がストツパ等に当つたことが明確に
分からず、処置に夢中になつている操作者は最大
起上以上にさらに起上させようとすることがあ
り、操作用ワイヤの伸び等の原因となつていた。 In addition, the treatment instrument has bending resistance, which makes it difficult to clearly see when the treatment instrument guide has hit a stopper, etc., and the operator, who is absorbed in the treatment, may raise the instrument further than the maximum elevation. This causes the operating wire to stretch.
本考案は上記事情に着目してなされたもので、

This invention was made with attention to the above circumstances,
The purpose of this is to make it possible to actually check the raised state of the treatment instrument guide within the field of view, which allows you to insert the treatment instrument with the treatment instrument guide inverted and perform treatment from the tip of the endoscope without realizing it. This improves safety by preventing the danger of unnecessary protrusion of the instrument and damaging the body cavity wall, and also prevents damage to the operation wire that activates the instrument guide due to the surgeon's excessive lifting operation. Our goal is to provide endoscopes.

むようにしたのである。 Furthermore, when the treatment instrument guide 19 is raised to the maximum as shown in FIG.
2 enters the field of view 13 as shown in FIG.
For example, it should be located around 1/4 of the field of view 13. Further, it is set so that the treatment instrument guide 19 does not enter the field of view 13 unless it is raised sufficiently. That is, the treatment instrument guide 19
When the distal end is at the height shown by the dashed line in FIG. 2 as in the conventional configuration, it does not enter the field of view 13 even if the treatment instrument guide 19 is raised to the maximum. However, in the present invention, it extends beyond this as shown by the solid line, and a portion 32 of it extends into the visual field 13.

As explained above, according to the present invention, it is possible to determine whether the treatment instrument guide is raised or not not by feeling with the hand but within the visual field. In addition, even an operator who is concentrating on the situation within the visual field can easily and reliably distinguish the information. Therefore, since the treatment instrument is inserted after confirming the raised state of the treatment instrument guide, it is possible to avoid the risk of unnecessarily protruding the treatment instrument into the body cavity and damaging the body cavity wall.

る。 In addition, conventional treatment instruments have bending resistance, so
It is not clear that the treatment instrument guide has hit a stopper etc. by the sensation of the hand, and the operating wire may be pulled strongly to raise it further than the maximum lift, but in this invention, the treatment instrument guide Since the raised state of the child can be clearly confirmed visually, there is no need to apply unnecessary force to the operating wire, and the operating wire does not stretch. Therefore, there is no deviation in the rising angle. In addition, since the storage chamber for the treatment instrument guide is placed parallel to the observation window of the objective optical system, treatment can be performed within the observation field of view without increasing the size of the treatment instrument guide or particularly widening the field of view of the objective optical system. It can be easily constructed so that the tool inductor can be observed and confirmed. Furthermore, since the storage chamber for the treatment instrument guide is arranged side by side with the observation window of the objective optical system, there is no need to lengthen the hard part of the distal end component, and the instrument can be easily inserted into a narrow lumen.
