A new needle for biopsy of pleura.
A new pleural biopsy needle is hollow with a movable stylet. Three millimeters away from the tip of the needle, there is a hook-like notch for holding the biopsied pleural tissue. Its tip is not sharp enough to damage the lung tissue. As the tip is closed by solder, the specimen does not slip easily. Compared with the Cope needle, biopsy with this needle is easier to perform, and the size of the specimen is much larger. There were no complications in 21 patients.
