2. Description of the Related Art In an endoscope, cells are collected,
In order to remove an affected part, a treatment tool such as forceps and an electric scalpel is used. In order to guide this treatment tool into the body,
The endoscope is provided with a forceps channel. One end of the forceps channel is located in the main body operation section, and the other end extends to a forceps outlet at the distal end of the insertion section. The main body operation unit is provided with a forceps port member at least partially protruding from the casing, and a passage for introducing a treatment tool is formed in the forceps port member. Here, the forceps channel is also used as a suction passage for sucking body fluids and the like, and a forceps stopper constituting a check valve is attached to prevent suction dirt from overflowing from this passage. It has become so.

Since the endoscope is inserted into a human body or the like, it is necessary to clean the endoscope every time it is used. In particular, the cleaning of the forceps channel used also as a suction passage must be performed carefully. Therefore, in order to ensure the integrity of the cleaning of the forceps channel, it is preferable that the forceps port member to which the forceps channel is connected can be easily attached to and detached from the casing of the main body operation unit.

In order to satisfy the above demands, the forceps port member is configured as a forceps port device of an independent unit separate from the casing, and this is simply formed without using a tool or the like. When the cleaning is performed, the forceps opening device can be completely cleaned by separating the forceps opening device from the casing of the main body operation unit.

However, for example, if an auxiliary water supply (or auxiliary suction) member is attached to the side surface of the forceps opening device, it will hinder the screwing, and the auxiliary water supply member will not be in the way. In order to achieve this, the position where the auxiliary water supply member is provided must be greatly protruded from the main body operation unit, and further, when the forceps opening device is fixed, the auxiliary water supply member cannot be controlled to be directed in a predetermined direction. Furthermore, even when the auxiliary water supply member is not attached, even when the forceps port device has a direction when the forceps port device is mounted on the main body operation unit, there is no guarantee that the forceps port device is always in a predetermined direction. Therefore, when the projecting member is provided on the side surface of the forceps port device, or when the forceps port device has directionality, it is not possible to use a method of simply fixing with the screwing means.

The present embodiment is configured as described above, and the forceps opening device 4 is detachable from the main body operation unit 1. That is, in order to mount the forceps opening device 4 on the connecting portion casing 1b of the main body operation section 1, the distal end portion of the forceps opening device 4 is inserted into the mounting portion 17 provided on the connecting portion casing 1b, and the auxiliary water supply is performed. The direction of the main body 22 is adjusted so that the member 24 faces a predetermined direction. When the sleeve 23 is screwed while the main body 22 is kept in this state, the screw 27 provided on the outer peripheral portion of the sleeve 23 is engaged with the screw 18 in the mounting portion 17. Then, when the rotating operation portion 28 formed on the sleeve 23 is rotated by a finger, the sleeve 23 is fastened to the mounting portion 17 of the connecting portion casing 1b. When the sleeve 23 is driven into the mounting portion 17, the main body portion 22 comes into contact with the bottom surface of the mounting portion 17, and is pushed to a position where it does not further advance into the mounting portion 17. When the sleeve 23 is further screwed in from this state, the distal end portion of the sleeve 23 comes into contact with the step portion of the projection 26 of the main body portion 22 and is pushed in the direction of being pushed into the mounting portion 17. The main body portion 22 is fixed so as to be sandwiched between the distal end portion of the sleeve 23 and the inner surface of the mounting portion 17. on the other hand,
Since the sleeve 23 is screwed into the mounting portion 17, the sleeve 23 is also fixed. As a result, the forceps opening device 4 is completely fixed to the connecting portion casing 1b.

As a fixing mechanism for fixing the sleeve 23 and the main body 22 so as not to rotate relative to each other, a protrusion 26 provided at the front end of the main body 22 is provided with a protrusion 26 at the front end surface of the sleeve 23 and the mounting portion 17. Although it is configured to be held between the bottom and the bottom surface, for example, as shown in FIG. 3, the turning piece 30 is fitted to the auxiliary water feeding member 24 and this turning piece 30 is It is also possible to make the sleeve 23 rotatable from the state shown by the imaginary line in the figure to the state shown by the solid line so that the engaging portion 30 a is pressed against the sleeve 23. Regulation of relative rotation between the main body 22 and the main body 22 can be performed. Then, as shown in FIG. 4, an annular seal member 31 is provided inside the turning piece 30.
Is attached, and a step portion 24a provided on the auxiliary water supply member 24 is provided.
If the seal member 31 is sandwiched between and the bottom surface of the attachment portion 17 in the connection portion casing 1b,
The mounting portion of the auxiliary water supply member 24 can also be sealed. Further, even in the case where the auxiliary water supply member is not provided in the forceps opening device, for example, a state in which the distal end portion is not formed in a direction orthogonal to the axis of the main body portion and is inclined in a predetermined direction. In other words, the present invention can be applied to a case where the main body has directionality, such as when the main body is directional.
