  • the band 640 may be attached to the outer circumferential surface of the cover 610 as shown in FIG. 11, and may be inserted and formed between the covers 610 when the cover 610 is manufactured.
  • the band 640 is preferably disposed radially with respect to the center of the cover 610 so that longitudinal expansion is not suppressed only at a specific portion.
  • the band 640 may be formed of a rubber material or a synthetic resin having a lower expansion ratio than the cover 610, or may be formed of a polymer material having less elasticity in the longitudinal direction. That is, the cover 610 and the band 640 have different expansion coefficients.
  • a cover 630 of a transparent material may be coupled to one end of the cover 610 so that the tip of the endoscope is protected from contaminants and the illumination and the camera located at the tip of the endoscope are not obscured.
  • the band 640 can also be applied to the endoscope cover portion 10, 20, 400 of another embodiment of the present invention.
  • the endoscope cover unit 10, 20, 60, 400 of the present invention can be used as a cover of not only the endoscope but also other surgical instruments.
  • the process of mounting and removing the endoscope cover portion to the endoscope is easy to improve the user's convenience.
  • the present invention relates to an endoscope cover mounting apparatus, and is applicable to various endoscope cover mounting apparatuses.

Abstract

La présente invention concerne un dispositif d'installation de couvercle d'endoscope et, en particulier, un dispositif destiné à installer un couvercle d'endoscope sur un endoscope en vue d'éviter une contamination de l'endoscope. Le dispositif d'installation de couvercle d'endoscope est caractérisé en ce qu'il comprend : une partie couvercle d'endoscope constituée d'un matériau élastique ; et une partie corps principal couplée à une extrémité de la partie couvercle d'endoscope et comportant un premier trou traversant dans lequel l'endoscope peut être inséré dans la direction longitudinale, la partie couvercle d'endoscope se dilatant lors de l'injection d'un fluide. Comme il est décrit ci-dessus, lors de l'utilisation du dispositif d'installation de couvercle d'endoscope de la présente invention, un procédé destiné à installer le couvercle d'endoscope sur l'endoscope et à retirer ce dernier de l'endoscope est facilité, et ainsi la commodité pour l'utilisateur est améliorée.
