Guide for steering wires for a steering mechanism for a steerable tool

A mechanical transmission system, MTS, for a steerable tool, which MTS has a proximal end, a distal end, a transmission shaft region, TSR, and transmission bendable distal part (TBDP) adjacent to the TSR that moves omnidirectionally responsive to actuation of the MTS at the proximal end, wherein the MTS comprises:

• a set of longitudinal members, LMs, configured to transmit actuating movement along the TSR to the TBDP,
• a set of longitudinal member, LM guides for guiding the set of LMs, which LM guide comprises a body having a proximal side, a distal side, and an outside edge, wherein the body of the LM guide comprises a set of channels comprising at least 2 channels arranged around a pattern of a fictive tube, each channel:
• passing from the proximal side to the distal side of the body,
• configured to retain an LM of the set in a fixed radial position around the pattern of the fictive tube,
• being connected to the outside edge of the body via a slot, wherein the slot has a width narrower than the channel width,
• wherein each LM is inserted into a channel of the set of channels of an LM guide such that they are arranged around the pattern of the fictive tube in a fixed radial position, and wherein each LM is disposed at one end with a longitudinal tail having a trailing end at one end attached to the LM and at the other end a leading end, wherein at least the trailing end is configured for passage through the slot of the LM guide, wherein the tail leading end is provided with an end stop having a width greater than the channel width to prevent entry of the end stop into the channel.
