A furring strip fastening member comprises a furring strip receiving plate having a through-hole and a female thread section latching section, a rear face plate having a through-hole, a spring section and a female thread section. The device comprises a machine frame and a building space that is positioned in the machine frame; an energy source that emits a beam for selectively solidifying the building material; and a ventilator that generates an airflow for cooling the energy source. The mechanical linkage is configured to translate a motive force from the motor into motion of the lighthead. Whether the obtained shock wave generation frequency is larger than a set value or not is decided. A tunneling device is inserted into the skin of the patient to form a subcutaneous tunnel through which the proximal end of the catheter is inserted.
