Title:
INSERTION PART, ENDOSCOPE, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/087461
Kind Code:
A1
Abstract:
An insertion part, an endoscope, and a driving method, applied in the technical field of endoscopes. The insertion part comprises: an insertion tube (1), a first deformation body (2), a first driving body (3), a second driving body (4), and a second deformation body (5) being sequentially arranged along the axial direction of the insertion tube (1). The first deformation body (2) and the second deformation body (5) can be deformed to be in contact with an inner wall of an insertion object (6) of the insertion tube (1); the first deformation body (2) can slide along the axial direction of the insertion tube (1), the first driving body (3) is fixedly connected to the first deformation body (2), the second deformation body (5) is fixedly connected to the insertion tube (1), and a relative position between the second driving body (4) and the second deformation body (5) is fixed; an acting force that enables the first driving body (3) and the second driving body (4) to move closer to or away from each other can be generated between the first driving body (3) and the second driving body (4). Advancing of the insertion part in the insertion object (6) is implemented by means of a driving structure at a foremost end.
