a lung is collapsed and the thoracoscope and surgical instruments are inserted into the thorax through any of three to four small incisions in the chest wall.

This procedure is called video-assisted thoracoscopic surgery (VATS). It involves making small incisions in the chest and inserting a thoracoscope (a thin, flexible tube with a camera) to examine the chest cavity. The surgeon can then visualize the chest structures on a monitor and perform any necessary procedures, such as biopsies or removal of diseased tissue, through the same small incisions.

its depend upon the procedure for doing lung biopsy(open lung biospy,needle biopsy,bronchoscopic biopsy,video-assisted thoracoscopic surgery and mediastinoscopy) the risk of death from needle biopsy is rare. The risk of death from open biopsy is one in 3,000 cases. In mediastinoscopy, death occurs in fewer than one in 3,000 cases.

One can find information on robotic assisted surgery on various websites like BartowRegional and StanfordHospital. One could also visit a local hospital and ask for more information about robotic assisted surgery.
