Benefits of technology

The patent describes a device for inserting a shank tool through a catheter to a specific position in a patient's body for medical purposes. The device includes a first rotating part and a second fixed part that can hold the tool in place. This allows for easy positioning and actuation of the tool using one user. The device also includes a cam disc that can be temporarily fixed in its position without the need for permanent intervention. The technical effects include improved precision and ease of use for medical procedures.

Problems solved by technology

Such uretero-renoscopes however can not only be used therapeutically, but also merely diagnostically, since the treating person can herewith view and diagnose the kidney tube or ureter in a direct manner.
A return of rinsing fluid at the outer side of the shank or through an additionally inserted auxiliary shank leads to an additionally expansion of the tissue and is disadvantageous with respect to a minimal invasive operation.
Furthermore, an overpressure can build up, such counteracting the flow of rinsing agent.

Embodiment Construction

[0064]Referring to the drawings, FIG. 1 by way of example shows an endoscopic instrument 1 which comprises a tubular shank 3 for insertion into a body cavity. The shank 3 is connected to a handling device 5 at a proximal end 4 and in its inner lumen forms a fluid channel 7. The shank 3 furthermore at a distal, bendable shank section 9 is configured in at least partly flexible manner, in order when necessary to be bent by way of the action of the handling device 5.

[0065]It is evident in a part-section A-A through the shank 7 that by way of example a first optical and / or electrical lead 11 for the illumination at the distal shank end 17, a second optical and / or electrical lead 13 for taking pictures at the distal shank end 17, a first working channel 15 and a second working channel 19 run in the fluid channel 7. An LED as a light source can be arranged at the distal end of the first lead 11, wherein the lead 11 serves as an electrical electricity supply lead to the LED. Alternatively ...

Abstract

An endoscopic instrument (1, 134), for inserting into a body of a patient, includes a tubular shank (3, 47, 137) which is coupled or can be coupled to a handling device (5, 135) and is with a working channel (15). A shank tool can be led through the working channel (15). The working channel (15) includes a proximal working channel opening (153) for inserting the shank tool and a fluid inlet (148) which is separate from the proximal working channel opening.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a United States National Phase Application of International Application PCT / DE2019 / 200130, filed Nov. 7, 2019, and claims the benefit of priority under 35 U.S.C. § 119 of German Application 10 2018 218 954.4, filed Nov. 7, 2018, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD[0002]The disclosure relates to an endoscopic instrument for inserting into a body of a patient, preferably as a disposable article for disposal after using once and preferably for the minimal-invasive diagnosis of kidney tubes and ureters as well as for the removal of kidney and urinary stones.TECHNICAL BACKGROUND[0003]The starting point of the invention are uretero-renoscopes as are known for instance from EP 2 986 237 B1. A shank of the uretero-renoscope is inserted into the body of a patient via the ureter, in order with a distal gripping means such as for instance a capture basket or a Dormia loop, to capture ...
