摘要：A needle for endoscopic surgery is curved into an arc of more than 180. degree.and twisted, so that it forms a part of a spiral, with a lateral offset between the needlepoint and barrel. The needle is sized to fit through a 10 mm trocar and is also blackened,to improve its visibility in a bloody field. The needle curvature is preferably not constantover its entire length, so that different sections have different radii of curvature. Theneedle is particularly well adapted for performing laporascopically a procedure (BurchColposuspension) that is used to treat female stress incontinence.
