Abstract

The specification describes endoscopes that enable varying stiffness of an insertion portion in an endoscope assembly. In one example, an actuator operates either a spring or a flexible tube to vary stiffness of the insertion portion. In alternative examples, an elliptical wheel arrangement or screw mechanism provides a means to increase stiffness of the insertion portion of an endoscope assembly. In further examples, fluid and gas may be used inside the insertion potion to vary stiffness by varying pressure of the fluid / gas.

Description

[0001] cross reference [0002] This specification claims priority to US Patent Provisional Application No. 62 / 043,647, filed August 29, 2014, which is hereby incorporated by reference in its entirety. [0003] This specification also claims priority to US Patent Provisional Application No. 62 / 066,760, filed October 21, 2014, which is hereby incorporated by reference in its entirety. technical field [0004] The present description generally relates to an endoscope unit having an insertion part, wherein the stiffness of the insertion part can be varied. Background technique [0005] Endoscopes have gained great acceptance within the medical community because they provide a means of performing surgery with minimal trauma to the patient, while enabling physicians to visualize the patient's internal anatomy. Over the years, many endoscopes have been developed, classified according to specific applications such as cystoscopes, colonoscopes, laparoscopes, upper GI endoscopes and...
