An irrigation/infusion bag comprises a central bag containing irrigation/infusion fluid connected to the tubing delivery system. A peripheral bag surrounds the central bag and includes an insufflation system. When inflated with a hand pump, the peripheral bag compresses the central bag to help deliver the fluid from the irrigation system under pressure and at a desired temperature maintained by the peripheral insulation around the central bag.

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.

The Christoudias endodissector is an instrument for dissecting, wiping, sponging or cleaning tissues during endoscopic surgery. The instrument includes a mesh gauze body at one end which is held securely and housed in a recess on the head portion of the instrument by teeth on a fixed and a pivotal jaw. The lower part of the head portion is mounted within a resiliently backed cylindrical locking sheath. The lower head portion becomes an elongated main stem which is mounted within a handle sheath at the other end of the instrument. A locking pin on the stem engages a groove on the locking sheath to maintain the jaws in position. Alternate embodiments involve a mushroom dissector and a cocoon dissector named after the configuration of the gauze body which is securely affixed on a complimentary shaft. An alternate embodiment involves a tubular instrument onto which a tubular endodissector tip is attached thus forming a working port through which additional instruments can be inserted. The invention also includes the method of making and using the Christoudias endodissector.

This invention comprises an instrument with a unique trigger mechanism for approximating any tissues that can physically reach each other during a performance of any laparoscopic procedure. The user friendly double grasper comprises an elongated cannula having visually coded jaws at one end which cooperate with an intermediate member. The visually coded jaws are connected to control means within the cannula which are coupled to tacile coded control triggers mounted to a longitudinal handle. Each trigger is spring loaded to passively close a particular jaw after manually opening the jaw. Both triggers may be operated individually or simultaneously with the same operating digit. The triggers include a dimple on one trigger and a bubble on the other trigger so that an operator may recognize which trigger corresponds to which jaw and thus control the jaws by feel. The jaws are also coded for visual recognition with different color or letter.

A versatile irrigation system dissector for laparoscopic surgery comprises an elongated lumen having an elongated slim tip electrode slidably mounted therein and having a cutting tip extendable therefrom at one end. The lumen is connected at the other end to a manifold mounted on a handle, which includes a pair of switches to regulate the inlet and outlet flow through the lumen for irrigation and suction purposes. A control panel on the handle regulates the current to the tip for either cutting or coagulating. Thus, several operations may be performed with a single handheld instrument in a highly efficient and rapid action.

An adaptor for an irrigation set which includes an elongated cannula having an enlarged portion opposite the operative end thereof and a downwardly extending channel removably coupled to the manifold of a standard or label suction irrigation set for suction and irrigation fluids. The manifold is connected to suction and irrigation lines through respective valves. A bracket extends downwardly from the enlarged cannula portion and a hand control panel is mounted thereon with switches to activate cutting and electrocoagulation with an electrode, which is retractable within the cannula.

A surgical mesh for repair of incisional and or ventral hernia with a fixation fin extending from one of the surfaces of the mesh usually along the midline of the surface. The closure of the hernia defect edges involves suturing to the fin to avoid the possibility of damage to internal organs during laparoscopic suturing. An alternate embodiment involves a flexible rod mounted in a tubular structure on the mesh axis. The tubular structure includes a central opening with an attached thread that permits removal of the flexible rod, which spreads the mesh open to facilitate fixation of the mesh onto the abdominal wall surface.

A scissor comprises a rigid blade with a fixed shape and an adjustable spring blade both pinned together at the end of the blade portions. The blades also comprise elongated leg portions extending outwardly from the junction with the blade portions and terminating in curved finger loops or a manipulating handle. The adjustable spring blade comprises a blade with spring like properties of the cutting edge which is continuously maintained in rotation around the fixed axis of the non-cutting edge of said rigid blade. When the scissors are open, the line of the cutting edge of the spring blade penetrates the plane of the opposing blade. This penetration stops when the scissors are closed. The rotation of the spring blade cutting edge may be clockwise or counter-clockwise but is always directed towards the sharp edge of the opposing blade of the scissors and thus continuously engages the sharp edge of the opposing blade at the cutting point.
