Endoscope with working channel and a control body
The invention relates to an endoscope with a working channel in an insertion tube, and a control body, on the distal side of which the insertion tube is connected, and an attachment body attached to the control body in a detachable manner, wherein the detachably fastenable attachment body includes a working channel assembly and a suction device assembly.
1. An Endoscope comprising:
a working channel in an insertion tube;
a control body, on the distal side of which the insertion tube is connected, the control body comprising an incomplete housing comprising a snap-in fastener; and
an attachment body detachably fastenable to the control body and comprising:
a working channel assembly;
a suction device assembly; and
a housing completion component detachably fastenable to the incomplete housing via the snap-in fastener, wherein the housing completion component fastened to the incomplete housing together form a grip between the working channel assembly and the suction device assembly, which is configured to be grasped by a user, wherein:
the working channel assembly comprises the working channel, which extends to the distal end of the endoscope, and
the suction device assembly comprises a suction line and a suction control valve provided on the suction line.
2. The Endoscope according to claim 1 , wherein
the detachably fastenable attachment body comprises an instrument inlet section which forms an entrance section of the working channel that can be accessed from outside.
3. The Endoscope according to claim 1 , wherein
the endoscope comprises the attachment body and an endoscope basic body comprising the control body, and
wherein the endoscope basic body does not comprise the working channel assembly and the suction device assembly.
4. The Endoscope according to claim 3 , wherein
the detachably fastenable attachment body is designed as a single-use body that can be disposed of after use, and
the endoscope basic body is designed as a multiple-use body that can be cleaned after use and reused.
5. The Endoscope according to claim 1 , wherein
the suction line comprises a proximal suction line section, that can be connected to a suction source, and a distal suction line section that extends to the distal end of the endoscope, and
the suction control valve is arranged between the proximal suction line section and the distal suction line section.
6. The Endoscope according to claim 1 , wherein
the incomplete housing of the control body has a groove running perpendicularly to the direction of extension of the control body, into which a section of the housing completion component of the attachment body can be fitted.
7. The Endoscope according to claim 1 , wherein
the working channel assembly and the suction device assembly of the attachment body are detachably fastened in the control body.
