Definitions

  • Klein ABSTRACT A forceps or similar tool having two arms pivotably connected to each other by a box lock comprising a male lock member on one arm and a female lock member on the other arm, forming a longitudinal slot, the male lock member extending through the slot and having a transverse bearing bore or coaxial bearing recesses in its opposite sides, and the walls of the slot being pressed against the opposite surfaces of the male member with such a force that the material of the slot walls starts to flow and a part thereof passes into the bore or the recesses and forms therein studs together serving as a pivot pin which therefore does not extend through the walls of the slots but only projects from these walls and integrally therewith into the bearing bore or recesses.
  • the present invention relates to improvements in forceps, tongs, pliers or similar tools, especially for medical purposes, in which the tool comprises two arms which are pivotably connected to each other by a socalled box lock.
  • Such a box lock of the known tools of this kind consists of a male lock part of a reduced thickness on one tool arm intermediate its handle part and the part fonning a jaw or the like and a female lock part in a corresponding position on the other tool arms in the form of a slotted part.
  • the slot of the slotted arm is widened and the other arm is passed through the slot so that the reduced part of this arm is located within the slot, whereupon the widened walls of the slot are pressed toward each other and against the opposite surfaces of the reduced part.
  • coaxial bores are provided in the two lock parts and a rivet or screw serving as a pivot pin is passed through these bores and secured to one or both walls of the slot.
  • a tool which is provided with a box lock of this construction has considerable disadvantages, especially when it is designed as a surgical or dental instrument.
  • Such instruments include, for example, hemostatic forceps, polypus forceps, clamp forceps, kidney-stone forceps, stomach clamps, auricle clamps, intestinal forceps, sponge, tampon and towel-holding forceps, clipapplying forceps, bronchus clamps, ananstomosis clamps, coarctation clamps, mosquito forceps, dissecting and ligature forceps and the like, and also tooth pliers, technical pliers, needle holders, bone rongeurs, and bone-cutting forceps.
  • a further object of the invention consists in designing such a forceps or similar too] in a manner so as to permit it to be produced much more easily and quickly than one of the known tools in which the two arms are likewise connected by a box lock.
  • the invention provides that, instead of employing a pivot pin in the form of a rivet or screw which extends through co-- axial bores in the two lock parts and pivotably connects the two arms of the tool to each other, at least one of the two main wall surfaces of the slot in one arm is provided with a studlike projection which is integral with this surface and engages pivotably into a bearing bore or bearing recess in the male lock part of the other arm which is located within the slot.
  • This construction has the advantage that the walls of the slot are not weakened by a bore but that, on the contrary, at least the wall of the slot with which the studlike projection is integral may be reinforced by this projection. Furthermore, there is no longer any danger that a crevice or contact corrosion may occur between the walls of the slot and the pivot or connecting element since the latter now forms an integral part of a wall of the slot.
  • this projection may be of an annular shape which engages into a corresponding annular recess in the male lock part of the other arm. While this male lock part of one arm which is passed through the slot of the other arm will be weakened only very slightly by this annular recess, this construction results in a very secure connection and a very accurate pivoting between the two arms of the tool since both the radially inner and outer wall surfaces of the annular projection form bearing surfaces which are rotatable around the corresponding walls of the annular recess.
  • the present invention further concerns a method of producing a forceps or similar tool which is designed in the manner as previously described.
  • This method consists in producing a slotted blank for one tool arm and an unslotted blank for the other arm which is provided with a male lock part which is to be located within the slot in the first arm and has a transverse bearing bore or a bearing recess in at least one side thereof, in sufficiently widening the slot of the slotted blank and in passing the unslotted blank so far through the widened slot that the male lock part of this unslotted blank will be located within the slot of the other blank and the axis of the bearing bore or recess will be in alignment with the points of the slotted walls through which the pivot axis of the two arms should extend, in then pressing the walls of the slot toward each other with such a force that they engage with the opposite surfaces of the male lock part of the arm which is passed through the slot and the material of at least one wall of the slot starts to flow and forms a projection which extends into the bearing bore or recess of
  • the two blanks may be pivotably connected to each other by a single operation, that is, by a pressing operation.
  • a single operation that is, by a pressing operation.
  • the invention has the further advantage that, when the walls of the widened slot are being pressed against the outer surfaces of the male lock part so that the material of the walls of the slot start to flow, this projection will be transposed from the outer side to the inner side of the slot wall and engage into the bearing bore or recess in the male lock part. Therefore, without being reduced in thickness by the compression, the slot wall carrying the projection will be reinforced by the latter.
  • FIG. 1 shows a plan view of a forceps or similar tool according to the invention
  • FIG. 2 shows an enlarged cross section which is taken along the line II II of FIG. 1;
  • FIG. 3 shows a side view of an original blank for each of the arms of a forceps as shown in FIG. 1 and seen in a direction at a right angle to FIG. 1;
  • FIGS. 4 and 5 show enlarged side views of a part of one of the arm blanks as shown in FIG. 3 in the condition after the slot has been milled into this blank and after the slot has been widened, respectively;
  • FIG. 6 shows an enlarged side view similar to FIGS. 4 and 5 of the unslotted or male part of the other arm blank which is to be inserted into the slot of the arm blank as shown in FIG. 5; while FIG. 7 shows a cross section similar to FIG. 2 ofa box lock according to a modification of the invention.
  • FIGS. 1 and 2 illustrate a surgical forceps or similar tool which comprises two arms 1 and 2 which are pivotably connected to each other by means of a box lock 4 so as to be pivotable relative to each other about an axis 3.
  • Each of these arms 1 and 2 consists of a jaw 5 and a handle 6 which are integrally connected by one or the other of the two members of the box lock 4.
  • One of these members is a female member which is formed by a slot 7 which is provided in the arm 1 intermediate its jaw 5 and handle 6 and extends through this arm at a right angle to the pivot axis 3.
  • the male member of the box lock 4 consists of a flat part 8 of the other arm 2 which extends through the slot 7 of the first arm 1 and likewise connects the jaw 5 with the handle 6 of this arm 2.
  • This lock member 8 is provided with a transverse bore 9 which is coaxial to the pivot axis 3 and serves as a bearing aperture the two outer edges of which are preferably beveled so as to diverge outwardly.
  • the two main wall surfaces of slot 7 facing each other are provided with coaxial studlike projections 11 which engage into the opposite ends of bore 9 in the lock member 8 and together act like a pivot pin in this bore 9 so as to permit the two arms 1 and 2 to pivot relative to each other about the axis 3.
  • FIG. 7 illustrates a modification of the box lock of a forceps or similar tool as shown in FIG. 1.
  • Those parts in FIG. 7 which functionally correspond to the parts as shown in FIGS. 1 and 2 are also designated by corresponding reference numerals which, however, for distinction are increased by over those as applied in FIGS. 1 and 2.
  • each side of this lock member 108 is merely provided with an annular recess 109 into which an annular projection 111 engages.
  • These projections 111 again extend coaxially to each other and to the annular recess 109 and project toward each other from the main walls of the slot in the slotted arm 1 of a forceps as shown in FIG. 1 and surround like bearing races the small studs remaining at the inside of the annular recesses 109 on the opposite sides of the lock member 108.
  • This embodiment of the invention has therefore the advantages over the embodiment as illustrated in FIGS. 1 and 2 that the male lock member 108 of one forceps arm is not weakened by a continuous bore 9 and that the walls of the slot in the other forceps arm are not only reinforced by the annular projections 111, but these projections are also guided on their radially inner and outer sides by the walls of the annular recesses.
  • equal original blanks 21 are first produced by drop forging for the two forceps arms 1 and 2.
  • Each of these original blanks 21 is provided between its jaw part 25 and the handle part 26 with two equal warlike projections 31 which extend coaxially to each other from the opposite sides of the blank.
  • these projections 31 it is only necessary to provide corresponding recesses in the upper and lower dies between which each blank 21 if forged.
  • These projections 31 serve as centering points for mounting each original blank 21 in the exact position in which it is to be machined.
  • the respective blank 21 is at first clamped in a very accurate position between a pair of jaws 32, as shown in FIG. 6, which are provided with coaxial bores 34 the edges 33 of which facing each other are beveled in accordance with the projections 31 on each original blank 21 which in this clamping position engage into the bores 34 and abut against their beveled end surfaces 33.
  • the slot 27 as shown in FIG. 4 is milled into this blank. Thereafter, this slot is widened to a shape substantially as shown in FIG. 5 so as to permit, for example, the machined jaw 5 of the blank for the other forceps arm 2 to be passed through this widened slot 27 until the male lock member 8 or 28 of this forceps arm 2 is disposed within this slot.
  • this blank while still being gripped by the clamping jaws 32 is also gripped at its jaw and handle parts, whereupon the clamping jaws 32 are opened so that the released section of this blank 21 is free for being machined so as to form the male lock member 28, as shown in full lines in FIG. 6.
  • the coaxial bores 34 in the clamping jaws 32 serve as guides for the smooth shanks of two drills 35 and 36. While drill 35 has a drill part of a smaller diameter than its shank and a chamfering shoulder on the upper end of this drill part, the other drill 36 is merely a chamfering drill.
  • the flat lock member 28 is first provided with a bore 29, the upper end of which is then chamfered by the chamfering shoulder of drill 35. Thereafter, this drill 35 is retracted and by means of the other drill 36 the lower edge of bore 29 is chamfered.
  • this arm is passed through the widened slot 27 in the manner and to the extent as previously mentioned.
  • the two arm blanks are then inserted into a press in such a position that bore 29 in the male lock member 28 will be in axial alignment with the common axis of the projections 31 on the female lock member, is. the slotted part of the blank for the forceps arm 1.
  • the press is then closed to such an extent that the walls 27 of the widened slot as shown in FIG.
