A push-to-close actuated, dual-action, spaced pivot, assembly for jaws, blades, and forceps devices. The assembly is structured for use with a push rod, cable, or solid wire forceps actuator surgical instrument. A jaw receiving body of the assembly is adapted to receive a wide variety of types of jaws performing different surgical functions. Two separate moving jaws each pivot about a separate spaced pivot pin, on opposite sides of the jaw body centerline. A handle with a pushing actuating rod provides a pushing motion to a drive rod, cable, or solid wire within a cable sheath to push a connected yoke in the assembly to push against the jaws to close the jaws together. |

1. A push-to-close actuated, dual-action, spaced pivot, assembly for jaws, blades, and forceps devices specifically structured for use with a push rod, cable, or solid wire forceps actuator surgical instrument and adapted for a wide variety of types of jaws performing different surgical functions, the device comprising:
a jaw retaining body attached to a distal end of a push-to-close cable forceps actuator surgical instrument, the jaw retaining body comprising a jaw receiving platform having a protruding right pivot pin on a first face of the jaw receiving platform spaced apart from a longitudinal center axis of the jaw receiving platform adjacent to a right edge of the jaw receiving platform and a protruding left pivot pin on a second face of the jaw receiving platform spaced apart from a longitudinal center axis of the jaw receiving platform adjacent to a left edge of the jaw receiving platform, thereby providing spaced pivot pins; two opposing moving jaws, each pivoting about one of the separate spaced pivot pins, each of the jaws comprising one of a pair of push-to-close actuated dual-action spaced pivot jaws on the distal end of the push-to-close rod, cable, or solid wire forceps actuator surgical instrument, so that a left jaw is pivotally connected to the right pivot pin on the jaw retaining body and a right jaw is pivotally connected to the left pivot pin on the jaw retaining body, each of the jaws further comprising an exposed hip on a proximal end of each of the jaws, spaced apart from each of the respective pivot pins, for receiving a pushing force on each of the exposed hips simultaneously to pivot the distal ends of the pair of jaws together for performing a surgical function, the distal ends of the pair of jaws comprising a mating pair of structural elements configured to perform at least one surgical function when the pair of jaws are pivoted together, each of the jaws having a détente adjacent to each of the exposed hips for receiving a pulling force to pull the pair of jaws apart, each of the pair of jaws having a pivot pin opening to receive one of the spaced pivot pins for attaching each of the jaws to the jaw retaining body so that different jaw sets having mating pairs of structured surgical elements to accomplish different surgical functions can be installed by the manufacturer on the same jaw retaining body; a yoke to open and close the pair of jaws, the yoke being operated by a drive rod, cable, or solid wire from a control handle on a proximal end of the push-to-close drive rod, cable, or solid wire forceps actuator surgical instrument, the yoke comprising a rigid yoke body attached to the drive rod, cable, or solid wire at a proximal end of the yoke body and two rigid spaced parallel arms rigidly extending from a distal end of the yoke body for operating the jaws, the spaced arms each comprising a pushing end in contact with one of the exposed hips of one of the pair of jaws to enable the pair of arms to push both of the exposed hips of the pair of jaws simultaneously pivoting the distal ends of the pair of jaws together to perform a surgical function, the spaced arms each further comprising a hook to engage one of the détentes of one of the pair of jaws to enable both hooks to pull the détentes simultaneously to pivot the distal ends of the pair of jaws open; the drive cable, rod, or solid wire comprising a pushing and pulling rod, cable or solid wire movably housed within a cable sheath extending between the jaw retaining body and the control handle, the control handle being held by a medical professional, the control handle having means for controlling the drive rod, cable, or solid wire to push the drive rod, cable, or solid wire to close the jaws and to pull the drive rod, cable, or solid wire to open the jaws, thereby providing a push-to-close actuated dual-action spaced pivot jaws forceps assembly specifically structured for use with a push rod, cable, or solid wire forceps actuator surgical instrument and adapted for a wide variety of types of jaws performing different surgical functions. |
