摘要:
A trocar tube, trocar, obturator, rectoscope is suitable for transluminal endoscopic surgery via natural body cavities. A trocar tube (2) has a distal section (22) for positioning at least in the region of or outside the body cavity, and a proximal section (21) for positioning within the human or animal, wherein at least the proximal section has a substantially rigid or inflexible curvature. An obturator (3) and a rectoscope (5) may be adapted for use with such a trocar tube for this purpose.
