Abstract

The coagulation forceps of the type in which a rod for the opening and closing of forceps jaws by reciprocal axial movement thereof extends axially through an externally insulated shaft, and is actuated by a handle comprising a pair of branches which are resiliently biassed apart from one another. To simplify construction while ensuring that the handle is well insulated from the HF supply to the forceps shaft, the two branches of the handle are connected to respective parts of the forceps by separately produced insulating elements. One of these elements is connected to the proximal end of the actuating rod while the other is mounted on the shaft and encloses a connector for the HF supply.
