Abstract: This patent application relates to a feeding device for tubular component, which comprises: a first driver and a first wheel set; and, a second driver and a second wheel set; wherein, the tubular component can be clamped between the first and second wheel sets, and be driven to move under the friction action of the first and second wheel sets; the first wheel set has a plurality of first driving wheels, travelling directions of which are parallel to each other, and form an angle with an extension direction of a clamped portion of the tubular component, the angle being an acute angle; the second wheel set has a plurality of second driving wheels, travelling directions of which are parallel to each other. The technical solution of the present application involves a simple structure, low cost, and ingenious principle, and has applicability to both rigid and flexible tubular components.

Abstract: A flexible endoscope system is provided for use in surgical operation which includes a head part and a control handle detachably connected using first and second docking keys. The head part comprises a shaft, a flexible tip located at a distal end of the shaft, an image sensor module, and drive tendons extending in the shaft for controlling the movement of the flexible tip in multiple degrees of freedom. The control handle includes multiple motors for tensioning or relaxing the drive tendons via a capstan assembly. Control element is provided on the control handle to allow a user to trigger a complex movement of the flexible tip to form an S shape so that a bird-eye view of the surgical site can be obtained by the endoscope system. The detachable connection eliminates the need to sterilize the control handle in which the main electronic components are located.
