AI Technical Summary

Technical Problem

In the prior art, the structural stiffness of the endoscope insertion part is low, resulting in the protective film easily forming wrinkles during the filming process, which is complicated and time-consuming to operate.

Method used

Using the insertion part sleeve film tool, the insertion part and the protective film are defined in the preload area through the first preloading wheel set and the second preloading wheel set. The protective film and the insertion part are moved simultaneously by the rotation of the first and second rotors, and the protective film remains tight in the entire sleeve process.

Benefits of technology

It effectively avoids the formation of wrinkles in the protective film during the membrane, simplifies the operation process, and improves the efficiency and convenience of the membrane.

Abstract

The present invention discloses an insertion part sheathing tool and an insertion part sheathing assembly, and relates to the technical field of endoscopes. The insertion part sheathing tool comprises: a first pre-tightening wheel group and a second pre-tightening wheel group. The insertion part of the endoscope is limited to a first gap defined by the first rotating wheel by setting a first pre-tightening wheel group having a first rotating wheel, and the protective film installation assembly is limited to a second gap defined by the second rotating wheel by setting a second pre-tightening wheel group having a second rotating wheel. The first rotating wheel rotates and transports the insertion part, and the protective film in the protective film installation assembly adheres to the surface of the insertion part as the insertion part moves. The insertion part can drive the protective film to move and gradually sheath on the outer surface of the insertion part. During the movement, the protective film will help the second rotating wheel to overcome its friction and drive the second rotating wheel to rotate, thereby making the protective film in a taut state during the entire sheathing process, solving the problem of wrinkles formed on the protective film when it is sheathed on the outer surface of the insertion part.
