An endoscopic or laparoscopic surgical instrument having an internally disposed ratchet mechanism located within a barrel portion of a handle assembly. The instrument includes a handle assembly having a pivoting handle and a stationary handle, a barrel portion to which an elongated body assembly is secured, and a ratchet mechanism for releasably positioning a tool mechanism located at the distal end of the body assembly at various increments. The ratchet mechanism comprises a pawl member and a rack member which are disposed within the handle assembly. A rotational knob and locking member may also be provided to lock the body assembly at various orientations to the longitudinal axis. The tool assembly includes novel atraumatic jaw mechanisms incorporating flexural characteristics to better gauge the force being applied to the captured tissue. The novel jaw mechanisms further includes increased tissue gripping surface area and multiple tissue handling portions which allow users to use fewer instruments and reduce the time to perform procedures.
An endoscopic or laparoscopic surgical instrument comprising: a handle assembly; an endoscopic portion having a proximal end connected to said handle assembly and a distal end mounting a jaw mechanism, said jaw mechanism including a pair of jaw members disposed in opposing relation wherein at least
An endoscopic or laparoscopic surgical instrument comprising: a handle assembly; an endoscopic portion having a proximal end connected to said handle assembly and a distal end mounting a jaw mechanism, said jaw mechanism including a pair of jaw members disposed in opposing relation wherein at least one jaw member is movable such that said jaw members may be positioned in at least an open position and a closed position, each said jaw member having a distal portion defining a first plane and including an elongated tissue gripping face, and a proximal jaw mounting portion defining a second plane substantially perpendicular to said first plane, each said jaw member further including at least one arcuate transition area intermediate said proximal portion and said distal portion to facilitate jaw flexure.
