1 B. Braun needle nomenclature To identify the different types of needles, B. Braun uses the following nomenclature: A B C 2 D Needle angle of curvature Body type Point type Needle length Wire size S /8 circle R round body T trocar point f thin V /4 circle S cutting needle N blunt point bodied needle This refers to the s heavy D 3/8 circle L lancet needle S sternum point distance between bodied needle H /2 circle C short cutting point the needle point ss extra heavy F 5/8 circle M micro-point and the needle end, bodied needle G straight MP precision point measured along the length of the v break-off P progressive curved m micro needle needle in mm needle J hook mv micro vascular SK ski needle B protection point b black needle Example: H R C 26 HRC 26 /2 circle round bodied needle with short cutting point, 26 mm long. Needle angle of curvature F H D S /8 circle V /4 circle D 3/8 circle H /2 circle F 5/8 circle Take off removable needle In order to remove the needle from the suture without the aid of scissors, one must pull the suture taut and secure and grasp the needle in the needleholder. A straight tug of the needleholder will then release the needle from the suture. Others V S J Hook G Straight P Progressive SK Ski 29
