Abstract

A sterile drape for covering a robot arm of a surgical robot according to an embodiment may include: a bag-shaped drape body formed with an opening at an end portion on one side of the drape body; and a mount cover provided at the other side of the drape body and configured to cover a mount section of the robot arm to which a surgical instrument is to be mounted via an adaptor. The mount cover includes one or more through holes. A protective film that is configured to be peelable from the mount cover is attached to the mount cover so as to cover the one or more through holes.

Claims (59)

1 . A sterile drape for covering a robot arm of a surgical robot, comprising:

a bag-shaped drape body formed with an opening at an end portion on one side of the drape body;

a pair of grip portions projecting outside from the end portion on the one side of the drape body in a direction parallel to a longitudinal direction of the drape body and formed integrally with the drape body; and

a mount cover that is provided at the other side of the drape body and is a flat resin plate including a first surface and a second surface opposite to the first surface, the first surface facing a mount section of the robot arm and the second surface facing an adaptor that attaches the mount cover to the mount section and to which a surgical instrument is to be mounted, wherein

the mount cover includes a plurality of through holes and is provided independently of the adaptor,

a protective film is attached to the second surface of the mount cover so as to cover all of the plurality of through holes, the protective film being configured to be peelable from the mount cover, and

a length of the protective film is longer than a length of the mount cover in the longitudinal direction.

2 . The sterile drape according to claim 1 , wherein

the drape body and the protective film are in different colors so as to be distinguishable from each other.

3 . The sterile drape according to claim 2 , wherein

the drape body is colorless and transparent, and

the protective film is colored.

4 . The sterile drape according to claim 3 , wherein

the mount cover is colorless and transparent.

5 . The sterile drape according to claim 1 , further comprising

an annular elastic string provided in the vicinity of the opening of the drape body and configured to fix the drape body to the robot arm.

6 . The sterile drape according to claim 5 , wherein

the annular elastic string is provided at a connection portion of the pair of grip portions to the drape body.

7 . The sterile drape according to claim 5 , wherein

the drape body and the annular elastic string are in different colors so as to be distinguishable from each other.

8 . The sterile drape according to claim 7 , wherein

the drape body is colorless and transparent, and

the annular elastic string is colored.

9 . The sterile drape according to claim 5 , wherein

the annular elastic string comprises a rubber string.

10 . The sterile drape according to claim 1 , wherein

the pair of grip portions are arranged facing each other in a direction sandwiching the mount cover along a direction orthogonal to the longitudinal direction of the drape body.

11 . The sterile drape according to claim 1 , wherein

the pair of grip portions are formed of a same material as the drape body and formed integrally with the drape body.

12 . The sterile drape according to claim 1 , wherein

in a state before the drape body covers the robot arm, the drape body is folded inward in such a manner that an outer surface of the drape body, which is to be exposed to the outside in a state where the drape body covers the robot arm, is not exposed to the outside.

13 . The sterile drape according to claim 1 , wherein

the drape body has a shape in which an end portion on the other side of the drape body is linearly closed, wherein a corner of the end portion on the other side of the drape body is chamfered.

14 . The sterile drape according to claim 1 , wherein

the protective film is peeled off after covering the robot arm with the drape body and before attaching the adaptor to the mount section of the robot arm via the mount cover.

15 . A surgical robot comprising:

a robot arm to which a surgical instrument is to be attached; and

a sterile drape configured to cover the robot arm, wherein the sterile drape comprises:

a bag-shaped drape body formed with an opening at an end portion on one side of the drape body;

a pair of grip portions projecting outside from the end portion on the one side of the drape body in a direction parallel to a longitudinal direction of the drape body and formed integrally with the drape body; and

a mount cover that is provided at the other side of the drape body and is a flat resin plate including a first surface and a second surface opposite to the first surface, the first surface facing a mount section of the robot arm and the second surface facing an adaptor that attaches the mount cover to the mount section and to which the surgical instrument is to be mounted, wherein

the mount cover includes a plurality of through holes and is provided independently of the adaptor,

a protective film is attached to the second surface of the mount cover so as to cover all of the plurality of through holes, the protective film being configured to be peelable from the mount cover, and

a length of the protective film is longer than a length of the mount cover in the longitudinal direction.

16 . The surgical robot according to claim 15 , wherein

the pair of grip portions are arranged facing each other in a direction sandwiching the mount cover along a direction orthogonal to the longitudinal direction of the drape body.

17 . The surgical robot according to claim 15 , wherein

the drape body has a shape in which an end portion on the other side of the drape body is linearly closed, wherein a corner of the end portion on the other side of the drape body is chamfered.

18 . A sterile drape for covering a robot arm of a surgical robot, comprising:

a bag-shaped drape body formed with an opening at an end portion on one side of the drape body;

a pair of grip portions projecting outside from the end portion on the one side of the drape body in a direction parallel to a longitudinal direction of the drape body and formed integrally with the drape body; and

a mount cover that is provided at the other side of the drape body and is a flat resin plate including a first surface and a second surface opposite to the first surface, the first surface facing a mount section of the robot arm and the second surface facing an adaptor that attaches the mount cover to the mount section and to which a surgical instrument is to be mounted, wherein

the mount cover includes a plurality of through holes,

a protective film is attached to the second surface of the mount cover so as to cover all of the plurality of through holes, and is configured to be peelable from the mount cover,

the drape body and the mount cover are provided independently of the adaptor, and

the protective film is peeled off after attaching the mount cover to the mount section of the robot arm and covering the robot arm with the drape body and before attaching the adaptor to the mount section via the plurality of through holes of the mount cover.

19 . The sterile drape according to claim 18 , wherein a length of the protective film is longer than a length of the mount cover in the longitudinal direction.

20 . The sterile drape according to claim 18 , wherein

the pair of grip portions are arranged facing each other in a direction sandwiching the mount cover along a direction orthogonal to the longitudinal direction of the drape body.
