Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an adapter for a forceps channel in an endoscope, and more specifically, it is attached to the opening on the hand side of the forceps channel, and is used for suctioning the forceps channel. This article relates to an adapter that can be used for both purposes.

(Prior Art) Generally, an endoscope is provided with a forceps channel inside the main body for inserting a treatment instrument such as biopsy forceps or a laser probe (hereinafter referred to as "forceps"). This forceps channel is used not only for inserting forceps, but also for various functions such as injecting anesthetic solution or the like, or suctioning and removing mucus, dirt, etc. in a body cavity. The forceps channel usually has an opening in the hand operation section of the endoscope, and an adapter is attached to this opening to be used for the various functions described above. As an example of this adapter, the one disclosed in Utility Application No. 1362 (1982) (Utility Model Publication No. 116301/1983) filed by the applicant on January 11, 1980 is in practical use. has been made into In such an adapter, the forceps insertion port itself also serves as a suction control port that controls suction by opening and closing with fingers.

(Problem to be solved by the invention) However, when the forceps insertion port and the suction control port are in the same part, the forceps channel and the forceps insertion port are on the same axis, so that For example, if it is a bronchial tube, foreign matter such as sputum may come out, making it unhygienic. Also, when using forceps, there are disadvantages such as the inability to control the suction. It can be said to be a thing.

(Means for solving the problem) Therefore, in view of the above, this invention provides a forceps insertion port and a suction control port in separate parts,
Moreover, the suction control port is provided at a position offset from the axis of the forceps channel.

(Function) The adapter configured in this manner can be operated hygienically without foreign matter such as phlegm flying out from the vent that can be opened and closed with fingers for suction control.

(Example) Hereinafter, a forceps channel adapter for an endoscope based on this invention will be described in detail based on an example shown in the accompanying drawings.

In FIGS. 1 to 3, reference numeral 1 denotes an eyepiece 2, a release button 3 of a camera attached to the eyepiece 2, and an operation lever for controlling the bending of an angle portion provided in a body insertion part (not shown). 4 shows the hand-held operation part of the endoscope. On the upper side of the hand operation section 1, there is provided a hand side opening 5 of a well-known forceps channel extended in the insertion section. The adapter 10 according to this invention is detachably attached to the opening 5 on the hand side. As is clear from a comparison between FIG. 1 and FIG. 2, this adapter 10 includes a fitting part 11 that is fitted into the opening 5, a main body part 12, and a flexible pipe 20 that is attached to a well-known suction device (not shown). It is composed of a pipe connecting part 13 that is connected via a pipe connecting part 13. This adapter 10
As shown in FIG. 1, a forceps insertion guide hole 14 is formed through the forceps insertion hole 14, which coincides with the axis of the opening 5 when the forceps are inserted and connected. This guide hole 14 has a first taper 14a on its upper end side that fits into the outer peripheral taper of the injection port of the syringe barrel, and a second taper 14b having a larger slope than the first taper 14a.
A forceps plug attachment port 14c is provided with a diameter larger than the maximum inner diameter of the second taper 14b. The second taper 14b has a communication port 14d formed in communication with the pipe connection portion 13.
is provided. On the outer periphery of the fitting part 11,
An O-ring 15 for liquid-tight fitting when inserted into the opening 5 and a C-shaped click spring 16 for click engagement to prevent slipping out are provided, and a concave notch in the opening 5 is provided. An engagement pin 17 is provided that engages with 5a and prevents it from rotating. A vent hole 18 is provided in the middle of the pipe connection portion 13, which can be opened and closed directly with fingers. In FIG. 4, reference numeral 30 indicates a forceps plug, and this forceps plug 30 has a notch 31 in the center into which forceps can be inserted.
and an engagement flange 32 that engages with the flange 19 of the adapter 10. Further, in FIG. 3, the reference numeral 50 is a rubber cushioning between the operating portion and the upper wall surface.

The forceps channel adapter 10 in the endoscope configured as described above is used with the forceps channel adapter 10 attached to the opening 5 and the forceps plug 30 attached, as shown in FIG. When using this adapter 10, although the suction device (not shown) is kept in continuous operation, since it is released to the outside air through the vent 18, suction through the guide hole 14 and the forceps channel is not possible. If this is not done and the foreign matter inside the body is to be suctioned, the foreign matter inside the body can be suctioned by closing the vent 18 with the fingers 40 as shown in FIG.

(Effects of the invention) As is clear from the above description, the forceps channel adapter in the endoscope based on this invention provides an adapter for the forceps channel on the axis of the opening of the forceps channel and on the path of the aspirate to be aspirated. Since there is no vent hole that faces directly and can be opened and closed directly with fingers, there is no possibility that aspirated matter such as phlegm will stick to fingers as in the conventional case, making it extremely hygienic. In addition, the ventilation hole is placed in a cylindrical body placed along the outer wall of the hand-operated part, and the ventilation opening can be opened and closed with the fingers of the hand without having to change hands to grasp the hand-operated part. The opening makes it extremely easy to operate.
