METHOD FOR SURGICAL FUME EVACUATION IN ENDOSCOPIC THYROID SURGERY Russian patent published in 2024 - IPC A61B17/94 A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery. After the antiseptic treatment of the surgical site, a mucous membrane and a submucous layer in the lower fornix of the oral vestibule are infiltrated. Subcutaneous fat is infiltrated in the submental region and in the submental triangle with a solution of epinephrine in ratio of 1 mg of epinephrine per 500 ml of normal saline. Linear incision of the mucous membrane in the lower fornix of the oral vestibule is 1 cm long. Tunneller is used to form a subplasmic space. Further, 10-mm trocar with a gas supply valve is placed in the centre of the linear mucosal incision in the lower fornix of the oral vestibule. On both sides of it through additional 5-mm incisions, 5-mm trocars for endoscopic instruments are inserted and carbon dioxide insufflation is performed to a pressure level of 5 mm Hg. Then, the skin is incised in the right axillary region with length of 3.0 cm. Subcutaneous fat is separated to a medial crus of the right sternocleidomastoid muscle, and a tunnel is formed through which 16-mm trocar is placed to evacuate the surgical smoke. Required volume of the working cavity is formed with harmonic scissors and monocoagulator through 5 mm trocars. Thyroid gland is exposed, mobilized and removed in an endoscopic container through a skin incision made in the right axillary region.

EFFECT: method enables evacuating the surgical smoke in endoscopic thyroid surgery, providing persistent adequate visualization of the surgical field through the endoscopic camera and avoiding a surgeon’s work interruption.
