  • Patent number: 4096864
    Abstract: Surgical forceps are disclosed which consist of first and second legs attached at one end in a tweezer-like configuration. One of the legs includes a small conduit which terminates in one or more inlets disposed on the inner and outer surface of the tweezers. The opposite end of the conduit is adapted for connection to a source of vacuum to permit fluid to be drawn away from a surgical area. In an alternative embodiment, a similar conduit is formed in the other forceps leg which is adapted for connection to liquid under pressure, terminating in one or more openings on the inner and outer surface of the tweezer legs to permit cleansing of the surgical area. In either embodiment, the conduits are selectively extendable beyond the tip of the forcep leg by movable tubes which allow the suction of fluid supply to reach into areas removed from the forcep leg. Fluid control means are provided on the tweezers for both the vacuum conduit and the liquid supply conduit.
