Embodiment Construction

[0041] A further understanding of the present disclosure can be obtained by reference to the following description and drawings, wherein like elements are designated by the same reference numerals. Exemplary embodiments describe an endoscopic device (eg, an endoscope) having an endoscopic shaft that is separate from its associated endoscopic handle. This allows different types of handles to be connected to different types of shafts. Various embodiments will be described, including housing connections, electrical connections, and, in embodiments including a scope shaft with a deflectable distal tip, pull wire connections. In some embodiments, the connection between the shaft and the handle allows the handle to rotate relative to the shaft. Endoscopes may be completely disposable, or include some reusable components while other components are disposable. Also described are contamination barriers that can be used to protect the reusable one or more handle portions from contamin...

Abstract

The invention discloses an endoscopic device. The endoscopic device includes a handle body operably coupleable to a shaft housing. The handle body includes an actuator for controlling a distal end of the endoscope shaft extending from the shaft housing. The device also includes a pull wire attachment configured to be operatively coupleable to a pull wire that extends through the shaft housing and the endoscope shaft to the distal end. Application of tension to the pull wire deflects the distal end of the endoscope shaft. Further, the apparatus includes a traction mechanism coupled to the actuator and having a pull wire attachment extending therefrom. When the pull wire attachment is operatively coupled to the pull wire, actuation of the actuator applies tension to the pull wire and deflects the distal end of the endoscope shaft.

Description

[0001] claim of priority [0002] This disclosure claims priority to US Provisional Patent Application Serial No. 62 / 911,749, filed October 7, 2019; the disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to an endoscopic device having separate shaft and handle portions that are selectively coupled (physically and electrically) to each other. Background technique [0004] As understood by those skilled in the art, the endoscope may include a flexible or rigid shaft coupled with a handle that includes controls and interfaces for other equipment. Control of the endoscope can be implemented via actuators on the handle (eg, buttons, deflection knobs, etc.) to deflect the distal tip of the flexible shaft to change the orientation of the distal tip relative to the anatomy, eg, to change the distal tip. A camera on the lateral tip provides a view to align a tissue treatment or diagnostic device advanced from the distal e...
