Abstract

This invention comprises an instrument for peritoneal approximation following the application of mesh in a laparoscopic herniorrhaphy or for approximating any tissues that could physically reach each other during the performance of any laparoscopic procedure. The Maritsa Tissue Approximator comprises an elongated cylinder which is divided into two elongated compartments by a central plate which extends outwardly from the bottom of the cylinder. The head of the instrument comprises the outwardly extending fixed plate and two independently controlled jaws which close separately over the fixed central plate. The jaws are pivotally mounted onto a lateral extension of the center plate by pin-means about which they rotate thus opening or closing over the fixed central plate. The rotation about the pin is caused by a control wire which extends through a compartment of the cylinder and is affixed to a pivotal member at the other end of the instrument. The two jaws are each controlled by operation of a separate pivotal member which is resiliently backed against the handle and moved in conjunction with the pressure applied thereto, thus opening or closing the jaws on the opposite end of the instrument to expeditiously move a tissue flap into approximation with the opposite flap to facilitate stapling of the incision.
