Definitions

  • 111,269 arms forming a generally U-shaped configuration having a closed end and an open end, the arms extending in a longitudinal direction in a given plane and movable toward and away Fol'flgll Application Priority Data from each other in said plane, the arms being generally T- shaped in cross-section, the arms being joined at the closed Feb. 19, 1969 Australia ..5071 1/69 end of the forceps y a thin hinge strip of resilient plastic material moulded integrally with the arms, said thin stn'p hav- U'S.
  • FORCEPS This invention relates to improved surgical forceps and more particularly to forceps manufactured from thermoplastic materials.
  • the normal pattern of plastic forceps involves the manufacture by injection moulding of a generally U-shaped unitary construction having two arms tapering to points at their forward ends as seen in side view, and having serrations to permit gripping of sutures or other articles.
  • the arms are usually T- shaped in cross-section and arrangements must be provided whereby they can be caused to move relative to each other.
  • a still further object of the invention is to provide a pair of plastic surgical forceps in which sideward deflection of the arms will be minimized.
  • This arrangement permits even bending of the points of the forceps towards each other but, if the length of the strip of thin material measured around the configuration of the U is unduly great, the forceps can be weakened and there will be sideward deflection of the arms relative to each other as pressure is applied to cause the points to meet.
  • the strip of joining material is of relatively short length as compared with its width.
  • FIG. I is a front elevational view of a pair of surgical forceps according to the invention.
  • FIG. 2 is a side view of the same forceps
  • FIG. 3 is a sectional view on line 3-3 of FIG. 1,
  • FIG. 4 is a sectional view on line 44 of FIG. ll.
  • FIG. 5 is a sectional view on line 5-5 of FIG. 1, and
  • FIG. 6 is a fragmentary side elevational view corresponding to the left-hand end of FIG. 1 and illustrating an alternative form of the invention.
  • the forceps in accordance with normal practice, are of generally U-shaped configuration and are provided with serrations 10 for gripping purposes on the end faces of the arms 12, 14.
  • Each arm is generally T-shaped in cross-section as can be seen more distinctly in FIG. 4.
  • each arm is provided with two projections 18, 20 and 22, 24, respectively, of which projection 18 is opposite projection 22 and projection 20 is opposite projection 24.
  • projections 18 and 24 is displaced from the general surface of web 16 to the left as viewed in FIG. 3, and each of projections 20 and 22 is displaced from the general plane of web I6 to the right as viewed in FIG. 3.
  • each of the arms 12, I4 is provided with a series of ridges 26 which form a nonslip grip.
  • the arms taper to a point 28 at their free ends.
  • the web 16 is dispensed with to leave a strip of substantially flat thermoplastic material 30 which forms a hinge for the arms 12, 14. This enables the arms to move towards each other under light finger pressure but it has been found that, unless some form of reinforcement is provided and the length of strip 30 measured around the circumference of the U is made relatively small, the arms are readily deflected sideward and the projections 18, 22 and 20, M fail to interlock.
  • the reinforcement is provided by means of blocks 32 integrally moulded with the forceps and filling in the space either side of web 16.
  • FIG. 6 illustrates an alternative form of invention in which the blocks 32 have a somewhat different configuration giving a shorter strip 30 acting as a hinge for the arms.
  • the space on each side of the web 16 is filled to form a substantially solid mass of plastic material at the hinge end.
  • the forceps of the invention are preferably made by injection moulding of thermoplastic material.
  • Polypropylene is the preferred material but satisfactory results may be obtained with other thermoplastic materials such as polycarbonate.
  • a surgical forceps moulded from plastic material having two arms fonning a generally U-shaped configuration having a closed end and an open end, the arms extending in a longitudinal direction and movable toward and away from each other, the arms being generally T-shaped in cross section, the arms being joined at their inner ends at the closed end of the forceps by a thin hinge strip of resilient plastic material which resiliently holds the outer ends of the arms in space-apart relationship moulded integrally with the :arms, said thin strip having a small thickness dimension extending in said longitudinal direction, a width dimension, and a length dimension connecting together the inner ends of the arms, said length dimension being small in comparison to the width of the strip and said thickness dimension being less than the thickness of one of said T-shaped arms.
  • a pair of surgical forceps as claimed in claim 1 or claim 2 including reinforcing means at said closed end.
  • said projections interlock to prevent relative reinforcing means comprising an integrally moulded block filling in the space on either side of each web adjacent the closed end of the forceps, each block being integral with its respective web and with said thin hinge strip.
