Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

1 is a perspective view of an endoscope cover mounting apparatus 1 according to an embodiment of the present invention. The endoscope cover mounting apparatus 1 according to the first embodiment of the present invention includes an endoscope cover portion 10, a main body portion 300, and a fluid injection portion 310. [

The endoscope cover portion 10 is a component that surrounds the outer circumferential surface of the endoscope to prevent the endoscope from being contaminated by blood, body internal secretions, etc. The first cover 100, the second cover 110 and the third cover 120 . The first cover 100 is formed in a cylindrical shape having a through hole 101 in the longitudinal direction. A second cover 110 is connected to one end of the first cover 100 and a third cover 120 is connected to the other end. The second cover 110 is formed to have the same diameter as that of the first cover 100 and a through hole 111 communicating with the through hole 101 of the first cover 100 is formed. The third cover 120 is formed in a shape of a truncated cone whose diameter increases from one end to the other end and a through hole 121 communicating with the through hole 101 of the first cover 100 is formed.

10 is a perspective view of an endoscope cover part 60 according to the first embodiment of the present invention. The endoscope cover portion 60 according to the first embodiment of the present invention includes a cover 610 and a packing 620. [ The cover 610 has a cylindrical shape in which a through hole 611 is formed in the longitudinal direction and the packing 620 is positioned in the through hole 611 of the cover 610 in the shape of a truncated cone with a through hole 621 formed therein And one end is connected along one end of the cover 610. That is, the packing 620 is formed so that its diameter decreases from one end to the other end. According to an embodiment of the present invention, a cover 630 made of a transparent material may be formed at the other end of the cover 610. The lid 630 of a transparent material can prevent the endoscope from being covered with the cover 610.

A user inserts a part of the endoscope into the packing 620 through the through hole of the packing 620 and then inserts a part of the endoscope into the cover 610 through the working channel formed in the endoscope 60. [ As shown in FIG. At this time, the packing 620 seals between the cover 610 and the endoscope to prevent the fluid present inside the cover 610 from leaking. When the cover 610 is expanded to a diameter larger than the diameter of the endoscope, the user moves the endoscope until it abuts the lid 630 formed at the other end of the cover 610, And the fluid inside is discharged to the outside. When the fluid of the cover 610 is discharged to the outside, the cover 610 is brought into close contact with the outer peripheral surface of the endoscope.

At this time, it is preferable that the packing 620 is formed of a material having a smaller expansion rate than that of the cover 610 so that the packing 620 expands when the cover 610 expands and the adhesion between the cover 610 and the endoscope is not released. It is needless to say that the packing 620 and the cover 610 are integrally formed, but they can be formed and combined.

11 is a perspective view of an endoscope cover part 60 according to a second embodiment of the present invention.

The same components as those of the endoscope cover portion 60 of FIG. 10 described above are denoted by the same reference numerals, and a description thereof will be omitted. 10 is a plurality of bands 640 attached to the outer circumferential surface of the cover 610. The endoscope cover portion 60 of FIG. Bands 640 are arranged. The plurality of bands 640 suppress the expansion of the cover 610 in the longitudinal direction, thereby facilitating the insertion of the endoscope. At this time, the band 640 may be attached to the outer circumferential surface of the cover 610 as shown in FIG. 11 and inserted between the covers 610 when the cover 610 is manufactured. The band 640 may be formed only in certain regions,

It is preferable that the cover 610 is arranged radially with respect to the center of the cover 610. The band 640 may be formed of a rubber material or synthetic resin having an expansion coefficient lower than that of 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 to protect the end portion of the endoscope from contaminants and to prevent the illumination and the camera located at the distal end portion of the endoscope from being covered.

It goes without saying that the band 640 is also applicable to the endoscope cover portions 10, 20, and 400 of the other embodiments of the present invention. It is needless to say that the endoscope cover portions 10, 20, 60, and 400 of the present invention can be used not only as an endoscope but also as a cover for other surgical instruments.

The use of the endoscope cover mounting apparatus (1, 2) of the present invention facilitates the process of mounting and removing the endoscope cover unit on the endoscope, thereby improving convenience for the user.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of the present invention in order to facilitate the understanding of the present invention and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
