1. A medical apparatus comprising:
a light emission unit configured to emit excitation light, wherein the light emission unit comprises a light source and an optical fiber, wherein the optical fiber optically contacts the light source, and wherein the optical fiber has an end area for emission of the excitation light from the light source;
an ultrasound transducer;
an instrument channel; and
a hollow needle,
wherein the medical apparatus is configured to be arranged at least partly in an examination region of an examination object,
wherein the excitation light is configured to excite an optoacoustic emission of an ultrasound,
wherein the light emission unit is arranged at least partly in the hollow needle,
wherein the hollow needle is arranged at least partly for movement in the instrument channel,
wherein the instrument channel has an opening for bringing the hollow needle and the light emission unit out on a distal section of the medical apparatus,
wherein the ultrasound transducer is arranged on the distal section of the medical apparatus,
wherein the hollow needle is configured to puncture tissue in the examination region and to be moved out from the instrument channel at least partly through the opening of the instrument channel,
wherein the hollow needle is configured to bring out the end area of the optical fiber of the light emission unit into the punctured tissue via an opening of the hollow needle such that the end area of the optical fiber is positioned outside of the hollow needle, and
wherein the ultrasound transducer is configured for receiving the ultrasound.
