A curved trocar for thoracoscopy to obtain a multidirectional vision and operativity of the pleural cavity with less discomfort to patients undergoing thoracoscopy under local anesthesia. The trocar consists of an external rigid cannula which short arm (1) continues through a 60°-70° curve (2) into a long arm (3) provided with blocking system (4); an internal stylet formed by a body (5) with blocking spheres (6), conic tip (7) and handle (8), in nylon or other resistant material. Introduced the short arm into the pleural cavity through the intercostals space, the stylet is removed and a flexible fiberoptic device may be introduced in the cannula. Inclinating and rotating the cannula altogether with the fiberoptic device, vision and operativity are multidirectional. It is also possible to insert a thoracostomic tube in the chosen position.
