a first end of the suture, and disposed in a direction along a derivation direction of the suture and in a direction opposite to the derivation direction of the suture with respect to the first end of the suture. ## Claims ### Claim 1 A tissue ligating device for ligating a tissue, comprising: a suture having an elastic restoring force, and a hook-shaped member including a groove portion, connected to a first end of the suture, and disposed in a direction along a derivation direction of the suture and in a direction opposite to the derivation direction of the suture with respect to the first end of the suture, wherein the suture is configured to exert the elastic restoring force having a magnitude sufficient to prevent the hook-shaped member that is connected to the first end of the suture from falling over the tissue under the influence of gravity, and to maintain a state in which the hook-shaped member is separated from the tissue. ### Claim 2 (depends on 1) The tissue ligating device according to claim 1, wherein at least one portion of the suture is formed so as to be bent in a natural state. ### Claim 3 (depends on 2) The tissue ligating device according to claim 2, wherein the groove portion is disposed on an opposite side of the suture with reference to the first end of the suture. ### Claim 4 (depends on 1) The tissue ligating device according to claim 1, wherein a direction facing an opening of the groove portion from a bottom portion of the groove portion faces the first end of the suture. ### Claim 5 (depends on 1) The tissue ligating device according to claim 1, wherein the hook-shaped member includes a straight portion of which a first end portion is connected to the first end of the suture to extend in a straight-line shape, the groove portion is formed in a second end portion opposite to the first end portion of the straight portion to which the suture is connected, and the straight portion extends in a direction separated from the suture on a reference line, which is a central axis line of the suture through the first end of the suture. ### Claim 6 (depends on 5) The tissue ligating device according to claim 5, wherein the direction facing the opening of the groove portion from the bottom portion of the groove portion becomes substantially parallel to the straight portion, and faces the first end portion of the straight portion to which the suture is connected, and an inner wall surface of the groove portion extends to an outer peripheral surface of the straight portion. ### Claim 7 (depends on 5) The tissue ligating device according to claim 5, wherein the straight portion of the hook-shaped member is connected to the suture by coupling the first end of the suture with a fixing portion provided at one end of the straight portion. ### Claim 8 (depends on 1) The tissue ligating device according to claim 1, further comprising a suture needle connected to a second end of the suture. ### Claim 9 (depends on 1) The tissue ligating device according to claim 1, wherein a cross-sectional shape of the hook-shaped member defined by a plane orthogonal to a direction in which the hook-shaped member extends is a rectangular shape. ### Claim 10 A tissue ligating device for ligating a tissue, comprising: a suture having an elastic restoring force, and a hook-shaped member including a groove portion, connected to a first end of the suture, and disposed in a direction intersecting a derivation direction of the suture and in a direction opposite to the derivation direction of the suture with respect to the first end of the suture, wherein the suture is configured to exert the elastic restoring force having a magnitude sufficient to prevent the hook-shaped member that is connected to the first end of the suture from falling over the tissue under the influence of gravity, and to maintain a state in which the hook-shaped member is separated from the tissue. ### Claim 11 (depends on 10) The tissue ligating device according to claim 10, wherein at least one portion of the suture is formed so as to be bent on a bent reference plane in a natural state. ### Claim 12 (depends on 11) The tissue ligating device according to claim 11, wherein a direction facing an opening of the groove portion from a bottom portion of the groove portion faces a direction intersecting the bent reference plane. ### Claim 13 (depends on 12) The tissue ligating device according to claim 12, wherein the groove portion is disposed at a position closer to a middle portion of the suture than a disposition reference plane which is orthogonal to the bent reference plane and includes a reference line, which is a central axis line of the suture through the first end of the suture. ### Claim 14 (depends on 12) The tissue ligating device according to claim 12, wherein the groove portion is disposed at a position further separated from a middle portion of the suture than the disposition reference plane which is orthogonal to the bent reference plane and includes the reference line, which is the central axis line of the suture through the first end of the suture. ### Claim 15 (depends on 10) The tissue ligating device according to claim 10, wherein the hook-shaped member includes a straight portion of which a first end portion is connected to the first end of the suture to extend in a straight-line shape, the groove portion is formed in a second end portion opposite to the first end portion of the straight portion to which the suture is connected, and the straight portion extends in a direction intersecting the reference line, which is the central axis line of the suture through the first end of the suture. ### Claim 16 (depends on 15) The tissue ligating device according to claim 15, wherein the direction facing the opening of the groove portion from the bottom portion of the groove portion becomes substantially parallel to the straight portion, and faces the first end portion of the straight portion to which the suture is connected, and an inner wall surface of the groove portion extends to an outer peripheral surface of the straight portion. ### Claim 17 (depends on 15) The tissue ligating device according to claim 15, wherein the straight portion of the hook-shaped member is connected to the suture by coupling the first end of the suture with a fixing portion provided at one end of the straight portion. ### Claim 18 (depends on 10) The tissue ligating device according to claim 10, further comprising a suture needle connected to a second end of the suture. ### Claim 19 (depends on 10) The tissue ligating device according to claim 10, wherein a cross-sectional shape of the hook-shaped member defined by a plane orthogonal to a direction in which the hook-shaped member extends is a rectangular shape.
