METHOD OF BAKER'S CYST SURGERY Russian patent published in 2015 - IPC A61B18/22 A61B8/08 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to surgery, and can be applied in the treatment of Baker's cyst. An aspirating needle is introduced into the Baker's cyst cavity under the control of a US-sensor. A butt end light conductor is introduced into the needle lumen and passed to the fistula under the control of the US-sensor. An impact with laser radiation is realised with the wavelength of 1470 nm, radiation power of 8 W, pulse duration of 0.2-0.5 s and duration of 4-7 s until the fistula is obliterated. From the same puncture and by the same light conductor the coagulation of cyst walls is carried out with the radiation power of 8 W, pulse duration of 0.2-0.5 s and duration of 7-10 s.

EFFECT: method ensures the effective obliteration of the large cavity formation without the thermal injury of surrounding tissues, absence of disease recurrences due to heating remains of the intra-cavity serous fluid and denaturation of the internal layer of the cyst and fistula, which results in their strong adhesion.
