Summary:The utility model relates to a medical instrument, in particular to the head structure of a photo therapeutic instrument. The photo chamber of a therapeutic head is made into a full elliptical casing formed from the connection of two half elliptical casings. The special optical principle of two focal points of the ellipse can be made use of. A focal point sends a light source, and the other focal point receives the light source and guides out light for improving the optical efficiency and solving the problems of low optical efficiency for the therapy of the head and heat generation produced by high input power. A bulky water cooling system can be removed during the therapy process for a long time, and cost can be reduced and operation is convenient. The utility model can be widely used in various hospitals and families.
