Abstract:
1. An instrument for high-precision or surgical applications of a minimally invasive nature, comprising: a shaft defining a longitudinal axis and a radial direction perpendicular to the longitudinal axis; and a deflectable head positioned on a distal end of the shaft, wherein the shaft includes a proximal end equipped for directing the deflectable head, wherein the shaft is provided with a first construction element arranged internal to a ring of cables and a second construction element arranged external to said ring of cables comprising cables extending in a longitudinal direction of the shaft, the cables connected to the deflectable head and to the proximal end, wherein the cables are fixedly secured by said first and second construction elements in the shaft's radial direction and are movable in the shaft's longitudinal direction, and wherein each cable of the ring of cables is disposed such that at least a part of both sides of the cable is in direct contact with another cable of the ring of cables and extends parallel to the longitudinal direction of the shaft, and such that the ring of cables transmits a force from the proximal end to the deflectable head, which force causes the deflectable head to be manipulated from a position in which the deflectable head is aligned with the longitudinal axis of the shaft to a position in which the deflectable head is deflectable from the longitudinal axis of the shaft.
