Definitions

  • the present invention relates to medical forceps having a fixed jaw part with which a fixed grip part is associated and a movable jaw part which can be actuated by means of a swingable grip part which is coupled to the movable jaw part by a spring member which limits the actuating force.
  • the object of the present invention is to improve the forceps in accordance with the above-described prior art in such a manner that a practically constant force can be exerted on the two jaw parts regardless of how far the two grip parts are moved towards each other.
  • the swingable grip part consists of two parts which are on a line with each other and are undetachably connected to each other by a flexural spring member.
  • the outer part of the swingable grip part as well as the rigid grip part can be provided in this connection with handles and be equipped, in known manner, with detent elements which correspond to each other.
  • FIG. 1 is an overall side view of the forceps
  • FIG. 2 shows on a larger scale the part of the forceps of FIG. 1 which is developed in accordance with the invention.
  • FIG. 1 shows a forceps 1 having a rigid jaw part 3 and a swingable jaw part 2 which can be actuated via a pull and push rod (not shown) guided in the forceps shank 4 by means of a grip part 5 which is held against a rigid grip part 6.
  • the two grip parts 5 and 6 have detent elements 7 which can be brought into detachable engagement with each other via a profiled surface.
  • the grip part 5 consists of an inner part 9 and an outer part 10, said parts being connected in undetachable manner to each other by means of a flat spring 11.
  • the flat spring 11 is bridged over by support projections 12 and 13 except for a small space 14, a slight air space remaining between the support projections 12 and 13 and the flat spring 11.
  • the space 14 between the two support projections 12 and 13 of the parts 9 and 10 respectively is, to be sure, reduced even if the detent elements 7 and 8 are engaged with each other, but the surfaces of the support projections 12 and 13 which define the space 14 do not come against each other. If the forceps are used in a manner not in accord with their purpose, i.e.
