Access device and assembly comprising such device

Abstract

An assembly (1) comprising at least one steerable invasive instrument (10,20) and an access device (30) for introducing the instrument into an object via an access port of the object. The steerable instrument (10,20) comprises an elongated tubular body (18) having a proximal end part (11,21) comprising at least one flexible zone (14,15,24,25), a distal end part (13,23) comprising at least one flexible zone (16,17,26,27), and a rigid intermediate part (12,22). The instrument further comprises a steering arrangement for translating a deflection of at least a part of the proximal end part (11,21) relative to the rigid intermediate part (12,22) into a related deflection of at least a part of the distal end part (13,23). The access device (30) comprises a deflection setting arrangement for setting at least one angle between at least a part of the proximal end part (11,21) and the rigid intermediate part (12,22) of the instrument.

Description

technical field [0001] The invention relates to an assembly comprising at least one invasive instrument and an access device adapted to introduce the at least one invasive instrument into an object through an access port of the object. The invention further relates to such an access device. [0002] Assemblies and access devices according to the present invention can be used in both medical and non-medical applications. Examples of non-medical applications include inspecting and / or repairing mechanical and / or electronic hardware in hard-to-reach locations. Thus, the aforementioned object may be, for example, a human or animal body, as well as mechanical and / or electronic hardware. Therefore, terms used hereinafter, such as endoscopic application or invasive instrument, must be interpreted broadly. Background technique [0003] Converting surgical interventions that require large incisions to expose the target area to minimally invasive surgical interventions (ie, requirin...

AI Technical Summary

Problems solved by technology

[0009] A disadvantage of known access devices, such as those described in the above-mentioned documents, is that these access devices are more complex in construction and therefore more expensive due to the application of an expansion member, which is arranged distally of the access device, The expansion member is inside the object when the access device is used, and wherein the expansion member is operated by a control member arranged proximally of the access device, the control member is outside the object when the access device is used
