Single-hole (internal) thoracoscopic 1 cm surgical incision The standard 3 small incisions for surgical thoracoscopic surgery are implemented in our department Jin Minghua, Department of Thoracic Surgery, Shandong Chest Hospital Minimally invasive thoracoscopic surgery is performed by making several small holes of about one centimeter in the chest under local or general anesthesia and using professionally used instruments to operate on the patient. It reduces the pain and preserves the beauty of the chest while ensuring the efficacy of treatment. Thoracoscopy is divided into single-hole (medical) thoracoscopy and surgical thoracoscopy.

It is mainly used for pleural biopsy of pleural effusion, diagnosis and treatment of tuberculous pleurisy, talc pleural fixation of pneumothorax and pleural effusion, etc. It is less invasive, less painful, faster recovery, and can be performed on an outpatient basis. The cost is around RMB 2,000 – 3,000. Surgery Thoracoscopic techniques have expanded the scope of application of traditional thoracic surgery.
