Abstract:
1. A connector comprising: an outer tube; a hub disposed at a proximal portion of the outer tube so as to be movable in a direction of an axis of the outer tube and rotatable about the axis of the outer tube, relative to the outer tube, wherein the hub has a connection portion that is connectable on a proximal side of the hub to a medical instrument having a screw engagement part, the hub has a projected portion for screw engagement with the screw engagement part of the medical instrument, and at least a distal portion of the hub that is insertable in the outer tube; an engagement-disengagement mechanism provided at a joint part between the outer tube and the hub, wherein the engagement-disengagement mechanism permits rotation of the hub in both of a forward direction and a reverse direction when the hub is positioned in a first position, and inhibits the rotation of the hub in only one of the forward direction and the reverse direction when the hub is positioned in a second position on a distal side relative to the first position; and an elastically resilient member for biasing the hub in a proximal direction disposed within the outer tube at a distal side of the hub, wherein the hub is positioned in the first position by a biasing force of the elastically resilient member wherein the elastically resilient member expands to push the hub proximally towards the first position.
