Definitions

• ureteroscopes are used for endoscopic work in the ureter and renal pelvis.
• the ureteroscope is advanced from the outside through the urethra (urethra) into the bladder, from there through the ostium (mouth of the ureter with closure flap) into the ureter (ureter) introduced and advanced in this to the operating area For example, up to a stone or a narrowing in the ureter or to the renal pelvis.
• a ureteroscope is described in DE 1 0 2004 059 255 B3.
• the shaft tube preferably has a triangular polygonal shape in cross section. It is possible in the context of the invention that the triangular polygonal shape has rounded corners. Furthermore, it is possible in one embodiment that the polygonal shape is asymmetrical in cross section. Moreover, in one embodiment of the surgical instrument, it is preferred that inside the shaft tube has a shaft tube contact surface, preferably in cross section with a planar shaft tube contact surface portion and / or a curved shaft tube contact surface portion, for the at least two working channels.
• the working channels, each having a profile edge or a profile nose, are in this case arranged in the shaft tube on the shaft tube contact surface, whereby intermediate spaces and the distance between the working channels and the inside of the shaft tube are reduced.
• the working channels each have a working channel contact surface facing the shaft tube contact surface, wherein in particular the outer working channel contact surfaces of the working channels with the shaft tube contact surfaces, in particular with one respective shaft tube contact surface section for a Working channel contact surface, connected, preferably soldered, are.
• the working channels connected to each other via their facing contact surfaces, in particular soldered, and on the other hand, the working channels each have a the the inside of the shaft tube facing working channel contact surface and the working channel contact surfaces of the working channels are connected to the Schaftrohr Membership are no cavities in the Arrangement of the working channels in the shaft tube between the working channels and the shaft tube present.
• the working channels are formed such that each working channel is connected to a flat shank tube contact surface portion and a curved shank tube contact surface portion, whereby one or each working channel is associated with a round-shaped corner of the cross-sectionally polygonal shaft tube.
• the working channels and the shaft tube are each formed as metal tubes.
• the surgical instrument is preferably designed as a ureteroscope.
• Fig. 1 shows schematically a side view of a ureteroscope
• Fig. 1 schematically shows a rigid ureteroscope 10. It has a shaft part 1, at the proximal end of which a main body 2 is fastened with eyepiece 3 and insertion part 4.
• the shaft part 1 has an outer shaft tube 5 which determines the outer circumference.
• two inner working channels 6 and 7 are arranged (see Fig. 2) through which instruments are inserted.
• a light guide 1 3 see Fig. 2) and an optical channel with an optical system 1 2 (see Fig. 2) are further arranged, so that a picture of one at the distal End of the shaft portion 1 arranged lens is transmitted to the eyepiece 3.
