Abstract

A steering system (30) comprises two radially oppositely arranged drive wheels (1; 3) for steering a tubular object (5) positioned between the drive wheels (1; 3). The drive wheels (1; 3) each have a wheel rotation axis (40; 42) and each include a plurality of rollers (7) distributed around the wheel rotation axis (40; 42). The rollers (7) are rotatably arranged, each roller having a roller rotation axis (44) and an outer drive face (58) concavely vaulted in a direction corresponding to its roller rotation axis (44). The roller rotation axis (44) is obliquely oriented in relation to the wheel rotation axis (40; 42) and the rollers (7) of each drive wheel (1; 3) form together a steering periphery for the tubular object (5). The steering system enables continues rotation of a tubular object without danger that the object will lose the contact with the rollers. The steering system (30) may be incorporated in a catheter system which comprises a catheter (5).

Description

technical field [0001] The invention relates to a handling system comprising two diametrically opposed drive wheels for handling a tubular object located between the drive wheels. [0002] The invention also relates to a catheter system comprising such a steering system. Background technique [0003] An example of such a steering system, ie a catheter system, has been disclosed in patent application US2004 / 0254566A1. The known system comprises a device comprising two rollers arranged parallel to each other and perpendicular to the conduit between which the conduit is clamped. At least one roller is rotatably drivable, and at least one of said rollers is resiliently pressed against another roller, thereby providing a frictional grip of the inserted catheter. Due to the rotation of the drum in a clockwise or counterclockwise direction, the conduit moves longitudinally forward or backward, respectively. Simultaneously, at least one of the two rollers can move axially in its ...
