Problems solved by technology
[0010] A disadvantage of steerable instruments comprising diameter-adapted arrangements known from the prior art is that the construction of these instruments is rather cumbersome and therefore expensive, at least in the part of the diameter-adapted arrangement
Another disadvantage of steerable instruments comprising known diameter adaptation arrangements is that such arrangements have reduced reliability as they are more susceptible to failure due to damage
A further disadvantage of steerable instruments comprising known diameter adaptation arrangements is that such arrangements increase the diameter of the elongate tubular body of the steerable instrument
In cases where multiple steerable instruments are used during an intervention, the increased diameter of the steerable instrument's elongated tubular body can compromise its maneuverability, which is of course highly undesirable

Embodiment Construction
[0043] Figure 2a shows a side view of a non-limiting embodiment of a rigid invasive instrument 240, and Figure 2b A non-limiting embodiment of a steerable invasive instrument 10 is shown. figure 1 A non-limiting embodiment of an invasive instrument assembly 1 having an introducer with two such steerable invasive instruments 10 is shown. about Figure 2c to Figure 2k Details of a non-limiting embodiment of the steerable invasive instrument 10 are explained.
[0044] Such as Figure 2a The rigid invasive instrument 240 shown in includes an elongated shaft 242 having a proximal portion 241 and a distal portion 243 . At the distal portion 243, a tool 2, such as forceps, is arranged. At the proximal part 241 a handle 3 is arranged, said handle being suitable for manipulating the tool 2, ie opening and closing the jaws of the forceps. To this end, a control rod (not shown) is present inside the elongated shaft 242 , said rod connecting the handle 3 with the tool 2 . The rod...

A steerable instrument (10) for endoscopic and / or invasive applications, such as in surgery, the steerable instrument has an elongated tubular body (18) having a proximal end part (11), the proximal part has a first actuation flexible zone (14, 15), the first actuation flexible zone has a first diameter; and the distal part (13), the distal A portion has a first distal flexible zone (16, 17) having a second diameter different from said first diameter. A cylindrical diameter adapting section (164) is arranged to connect said proximal portion (11) to said distal portion (13) such that said first actuation flexible zone (14, 15) is relative to said Flexion of the longitudinal center axis of said longitudinal tubular body in radial direction causes an exaggerated or attenuated flexion of said first distal flexible zone (16, 17).
Description
technical field [0001] The present invention relates to a steerable instrument for endoscopic and / or invasive applications such as in surgery, the instrument comprising an elongated tubular body having a cylindrical diameter adapting section. Steerable instruments according to the present invention can be used in both medical and non-medical applications. Examples of the latter include inspecting and / or repairing mechanical and / or electronic hardware in hard-to-reach locations. Therefore, terms such as endoscopic application or invasive instrument used in the following description must be interpreted in a broad manner. Background technique [0002] Transforming surgical interventions that require large incisions to expose the target area to minimally invasive surgical interventions that require only a natural orifice or small incision to establish access to the target area is a well-known ongoing process. In performing minimally invasive surgical interventions, an operator...
