A wound closure device for closing a surgical wound, the device comprising: at least one clip for applying pressure to a patient's tissue, the clip comprising: a first clamping arm and a second clamping arm, each of the first and second clamping arms (12, 14) having a proximal first end (12a, 14a), an opposing distal second end (12b, 14b) and a sidewall (13, 15) extending therebetween, each sidewall (13, 15) having an interior surface (13a, 15a) and an exterior surface (13b, 15b), the exterior surface (13b, 15b) of each sidewall (13, 15) generally extending in a respective first plane; and at least one clamping tooth provided at the distal second end (11b, 14b) of each the first and second clamping arms (12, 14), the clamping tooth having a first leading surface, a second trailing surface opposed to the first leading surface, a base and a clamping tip positioned on an edge opposed to the base, characterized in that the leading surface generally extends at an angle (β 2) of 50° to 60° with respect to the first plane and the edge containing the clamping tip generally extends at an angle (β 1) of 5° to 15° with respect to the first plane. at least one clip for applying pressure to a patient's tissue, the clip comprising: a first clamping arm and a second clamping arm, each of the first and second clamping arms (12, 14) having a proximal first end (12a, 14a), an opposing distal second end (12b, 14b) and a sidewall (13, 15) extending therebetween, each sidewall (13, 15) having an interior surface (13a, 15a) and an exterior surface (13b, 15b), the exterior surface (13b, 15b) of each sidewall (13, 15) generally extending in a respective first plane; and at least one clamping tooth provided at the distal second end (11b, 14b) of each the first and second clamping arms (12, 14), the clamping tooth having a first leading surface, a second trailing surface opposed to the first leading surface, a base and a clamping tip positioned on an edge opposed to the base, characterized in that the leading surface generally extends at an angle (β 2) of 50° to 60° with respect to the first plane and the edge containing the clamping tip generally extends at an angle (β 1) of 5° to 15° with respect to the first plane. a first clamping arm and a second clamping arm, each of the first and second clamping arms (12, 14) having a proximal first end (12a, 14a), an opposing distal second end (12b, 14b) and a sidewall (13, 15) extending therebetween, each sidewall (13, 15) having an interior surface (13a, 15a) and an exterior surface (13b, 15b), the exterior surface (13b, 15b) of each sidewall (13, 15) generally extending in a respective first plane; and at least one clamping tooth provided at the distal second end (11b, 14b) of each the first and second clamping arms (12, 14), the clamping tooth having a first leading surface, a second trailing surface opposed to the first leading surface, a base and a clamping tip positioned on an edge opposed to the base, characterized in that the leading surface generally extends at an angle (β 2) of 50° to 60° with respect to the first plane and the edge containing the clamping tip generally extends at an angle (β 1) of 5° to 15° with respect to the first plane.
