Gross dressing forceps, also known as Gross forceps or tissue forceps, are surgical instruments designed at Dyna International for handling and manipulating various types of tissues, dressings, and other medical materials during surgical procedures. The term “box lock” describes the type of hinge mechanism used in these forceps. A box lock consists of two metal parts that interlock when the forceps are closed, providing stability and preventing them from coming apart during use. This design ensures that the forceps can withstand the forces exerted during surgery without slipping or separating.
