Laser treatment apparatus
View Patent ↗A laser treatment apparatus comprising a primary handset, the primary handset being connectable to an auxiliary attachment, the primary handset having a laser source having a primary heat exchanger, and a cooling circuit to provide cooling fluid to the primary heat exchanger to cool the laser source, the cooling circuit having an auxiliary circuit connection, for engagement with an auxiliary attachment.
1. A laser treatment apparatus comprising; a primary handset and an auxiliary handset, the primary handset being connectable to the auxiliary handset, the primary handset having a laser source, a primary heat exchanger and a main cooling circuit to provide cooling fluid to the primary heat exchanger to cool the laser source, the cooling circuit having a circuit connection for engagement with the auxiliary handset;
wherein the circuit connection comprises a fluid connection for connection to an auxiliary cooling circuit within the auxiliary handset;
wherein the auxiliary cooling circuit includes a secondary heat exchanger; and
wherein a one-way loop valve causes cooling fluid to flow in the main cooling circuit within the primary handset when no auxiliary handset is attached and to divert flow of cooling fluid to the heat exchanger in the auxiliary handset when the auxiliary handset is connected to the primary handset.
2. The laser treatment apparatus of claim 1 , wherein the auxiliary handset includes a tip window to transmit light from the laser source through the tip window.
3. The laser treatment apparatus according to claim 2 , wherein the auxiliary cooling circuit of the auxiliary handset cools the tip window.
4. A laser treatment apparatus according to claim 1 comprising one or more pumps to pump cooling fluid around the one or more of the main and the auxiliary cooling circuit.
