Inserting member lead-out device

An inserting member lead-out device for inserting a linear inserting member through wall-like tissues of the living body, the inserting member lead-out device comprising:

• a main body being arrangeable on one side of the wall-like tissues in a wall-thickness direction of the wall-like tissues;
• a perforating member for forming a perforation hole being perforated in the wall-like tissues in a first direction from the one side toward an other side, wherein the perforating member is movable relative to the main body;
• and
• a connector configured to connect the perforating member and the inserting member, wherein the connector comprises a first connecting portion being connectable to the perforating member at one end side of the connector and a second connecting portion being connectable to the inserting member at an other end side of the connector,
• wherein the perforating member has a tip portion, and a perforating shaft portion to be a part inserted into the wall-like tissues, wherein the perforating shaft portion is adjacent to the tip portion in a length direction of the perforating member,
• wherein a maximum dimension of the perforating shaft portion in a radial direction of the inserting member is smaller than an outer diameter of the inserting member,
• wherein the main body has a lead-out hole having an inner space extending along the first direction,
• wherein the perforating member is configured to be guided in the first direction and in a second direction opposite to the first direction in an interior of the lead-out hole coaxially to an axial center of the lead-out hole, and
• wherein the lead-out hole has a size allowing the connector and the inserting member to be inserted through the lead-out hole when the perforating member is moved in the second direction in a state in which the perforating member is connected to the connector with the connector being connected to the inserting member at the other side of the wall-like tissues.
