Definitions

  • ABSTRACT Surgical forceps for atraumatically gripping tissue during surgical procedures provides two parallel rows of teeth which interdigitate; they interlock but do not make direct contact. The rows of teeth are separated by a groove which extends into the jaw face below the base of the teeth for the reception of tissue.
  • Elongated members have opposed faces and resilient distal ends, at which ends the members are joined. The members are biased away from each other and require a small finger pressure to move the faces into an abutting relation. When the faces are forced into the abutting relation, teeth on the proximal ends interdigitate and positively grip, but do not puncture or otherwise injure, the tissue.
  • the present invention relates to surgical forceps adapted to grip tissue without causing injury thereto.
  • Another object of the present invention is the provision of surgical forceps which cause little or no injury to the tissue.
  • the present invention is preferably embodied in a tweezer-like structure having cooperating jaw portions.
  • a pair of elongated members are joined at distal, resilient ends.
  • the members are joined such thatthey are normally biased away from each other and need only a small amount of finger pressureto urge the faces into relative abutting relation.
  • the intermediate portions of the members are knurled so that the instrument can be positively grasped by the surgeon.
  • Each jaw comprises two parallel rows of teeth separated by a groove which extends intothe face of the elongated members below the teeth.
  • the teeth interdigitatewhen the jaws are forced together; that is, they interlock, but do not make direct contact in normal use.
  • the tissue gripped tends to fill the spaces between the teeth in an undulated or wave-like configuration. In this manner there is relatively'little puncture of the tissue and no injury of any other kind.
  • the interdigitating of the teeth permit the positive gripping of even very thin or delicate tissue without harm thereto.
  • the groove provides an additional area filled by'tissue, which tissue will be completely free of trauma.
  • FIG. 1 illustrates a side elevational view of the preferred embodiment of the instant invention.
  • FIG. 2 illustrates a plan view of a jaw section of the embodiment of FIG. 1.
  • FIG. 3 illustrates a perspective view of the jaws of the instant invention shown grasping tissue.
  • FIG. 4 is a greatly enlarged perspective view of a cluster of teeth.
  • the present invention consists of opposed elongated members l2, 14.
  • the distal ends l6, 18 of members 12, 14 respectively are tapered and joined at section 20. Those ends are resilient and biased away from each other requiring a small, but significant, finger pressure to urge the jaw sections 22, 24 into a mating engagement.
  • An intermediate portion of the outer faces is knurled to facilitate grasping by a surgeon.
  • jaw section 22 is shown in detail and it is to be understood that the description thereof is applicable to jaw 24.
  • the jaw 22 consists of two rows of teeth 26 separated by a groove 28.
  • the teeth 26 are longitudinally spaced and are generally identical.
  • the greatly enlarged view of a cluster of teeth in FIG. 4 illustrates the teeth 26 as generally pyramidal in shape.
  • the teeth 26 comprise a major base 30 and tapered and sloped walls 32, 34, 36, 38 which terminate in the tooth minor base or apex 40.
  • the groove extends into the face of the jaw below the major base 30.
  • teeth 26 on those jaws will mesh.
  • This meash is charac: terized by alongitudinal interdigitation by the various teeth; they interlock, but do not make direct contact in normal use.
  • the teeth of jaw 24 as shown in FIG. 4 will be designated the a teeth.
  • the cluster of teeth illustrated in FIG. 4 indicates that tooth 26 is centrally received between the teeth 26a with the apex 40 received in the space 42.
  • teeth 26a would be received between two teeth 26 on the opposing jaw.
  • the post 50 is connected to member 12 and bears against member 14 to prohibit the application of excessive pressure.
  • the post 52 is also attached to member 12 and received in hole 54 in member 14 to prohibit any lateral movement of the members with respect to each other which would destroy the alignment of the teeth.
  • the forceps embodied herein are particularly adapted for grasping very thin or delicate layers of tissue.
  • the tissue 44 when grasped lies within the spaces between the teeth 26 and tends to assume the shape of those teeth, however rounding out the edges. In other words, the tissue will assume an undulated or wave-like configuration. Additionally, a substantial portion of the tissue 44 will fall within the groove 28 and will be entirely free from pressure. In this manner there are many areas for gripping the tissue 44, but the teeth 26 do not puncture the same nor do they exert a substantial pressure thereon. The surgeon can deftly manipulate the tissue 44 without causing any trauma thereto.
  • Surgical forceps for atraumatically gripping tissue comprising a pair of opposed elongated members having confronting faces, said members including a rear resilient section and said members joined at said section such that said members are normally biased away from each other, said faces forcible into generally abutting relation with application of a relatively small amount of pressure, the forward ends of said faces comprising two parallel rows of pyramidal teeth separated by a groove which extends into said face below said teeth, said teeth on the opposed members being identical but longitudinally interdigitating when said faces are in said aubtting relation, said teeth adapted 3.
  • the forceps of claim 1 including a knurled inter-' mediate portion adapted for gripping by a surgeon.
