A light radiating device (A) performs solidification or cauterization of a biological tissue (PL) by radiating a light beam (BM). A light source (A) emits the light beam (BM). An optical waveguide (A) is a member being provided with a reflection surface (A) totally reflecting the light beam (BM) on an inner circumferential side wall, causing the light beam (BM) emitted from the light source (A) to enter a part enclosed by the inner circumferential side wall from one end, and sending the light beam (BM) to the other end. A catoptric system (A) reflects the light beam (BM) sent to the other end of the optical waveguide (A) and condenses the light beam (BM) on the biological tissue (PL).

Light radiating device

A cautery device for biological tissue, includes: a probe including a head unit that is configured to be inserted into a living body to emit light to cauterize the biological tissue, the head unit including a first fixing member, a second fixing member, and an exit hole, the exit hole being located between the first fixing member and the second fixing member, the exit hole allowing the light to be emitted therethrough; and an elongated catheter configured to sandwich the biological tissue between the probe and the catheter, to thereby support the biological tissue, the catheter including a third fixing member configured to fix the first fixing member and a fourth fixing member configured to fix the second fixing member.
