Abstract
Description
Technical Field
[0001] The utility model relates to a laparoscope type pleural fiberboard grasping forceps, belonging to the field of medical instruments. Background Art
[0002] Modern thoracic surgery is dominated by minimally invasive thoracoscopic surgery. Transitional and chronic tuberculous encapsulated empyema often cause extensive and severe adhesions in the pleural cavity due to long-term inflammatory stimulation, adhesions, fiber plate formation and even calcification, making this type of surgery a contraindication for thoracoscopic surgery. In recent years, some surgeons have overcome difficulties and used thoracoscopic surgery to treat the above diseases, but there is no effective instrument specifically for severe adhesions, tough and hard visceral and parietal pleural fiber plates and constricted pericardium. Due to the single function of the current pleural fiber plate grasping forceps, it cannot fully bite the visceral and parietal pleural fiber plates of varying thicknesses, and is therefore inconvenient to use.
