Problems solved by technology

This, although obviously providing more degrees of freedom, does not reduce the risk of intra-abdominal conflicts, since the endoscope on the distal side has to be positioned obliquely relative to the instruments
Furthermore, such flexible endoscopes are significantly more expensive, more prone to interference and more difficult to maneuver than rigid endoscopes

Embodiment Construction

[0022] figure 1 The arrangement of a rigid endoscope 1 with a working instrument 2 inside a trocar sheath 3 is shown. The trocar sheath 3 holds the access to the body cavity, which is substantially cylindrical and expands funnel-shaped on the proximal side. Here, the part that expands into a funnel is located outside the body, while the cylindrical part penetrates the skin and the abdominal wall and thus forms the access to the interior of the body.

[0023] If the working instrument 2 is pliers, its distal-side end effector 4 is actuated by means of two proximally arranged handles 5 , 6 . The end effector 4 and the handles 5 , 6 are connected by a straight rod 7 .

[0024] The endoscope, which is guided through the trocar sleeve 3 parallel to the rod 7 , has a rod-shaped central part 8 which is rectilinear and substantially parallel to the rod 7 . On the proximal side of the rod-shaped middle part 8 a control part 9 is connected, and on the distal side a distal part 10 is ...

Abstract

The invention relates to a rigid endoscope. The rigid endoscope has a shank-like middle part, on which a handle connects on a proximal side and which on a distal side includes a distal part with an optics window. The handle is arranged offset or obliquely to a longitudinal axis of the middle part, as well as of the distal part, in order to provide free space in the region of the handle of the working instrument as well as on the distal side of the tool.

Description

technical field [0001] The invention relates to a rigid endoscope. Background technique [0002] Such rigid endoscopes usually have a rod-shaped middle part, to which a control part is connected on the proximal side, and a distal part is connected to the distal side, wherein an optical window (Optikfenster) is provided in the distal part, the The optical window forms the viewing window in optical systems consisting only of optical components, while in electronic / optical systems forms the window for the beam path. Such rigid endoscopes can be designed as pure endoscopic optics or be equipped with one or more working / suction / rinsing channels through which one or more instruments can be introduced. [0003] Richard Wolf GmbH offers a rigid endoscope in the form of a laparoscope under model number 8915.402. The laparoscope has a control part at the end of which is provided a peep hole of the endoscopic optical system, which is arranged obliquely with respect to the longitudina...
