Definitions
- the jaws are loaded with at least one open surgical clip in preparation for surrounding the vessel or other tissue.
- the jaws are then closed and the clip applier inserted through a trocar cannula so that the clip may be positioned adjacent the vessel or other tissue.
- the jaws are then opened and the clip compressed onto the vessel or tissue.
- the size of the vessel or tissue to be clipped is limited by the size of the available clip. In general, a larger vessel or section of tissue requires a larger clip. However, since the clip applier must pass through the cannula of the trocar, its overall outer diameter ⁇ uist be less than that of the cannula. Also, since the clips are typically stored within the elongate body, the overall outer diameter of the clip applier may limit the size of the clips. Thus, there is a need for a clip applier which can be used with conventional trocars but which is not limited to conventional sized clips.
- the present invention also satisfies the need for a clip applier which allows a surgeon to control the closure or compressive force applied to a clip.
- this clip may be applied without over- compressing the tissue.
- This closure control is accomplished by using pre-compressed clips which are placed over a section of tissue which has been compressed by the jaws without need for any compression of the clip.
- the clip applier of the present invention allows a surgeon or other user to further compress the clip if desired, by further actuating the jaw members.
- the actuating mechanism is attached to the outer body and coupled to the jaw members such that actuation of the actuating mechanism moves the jaw members between an open position, a first closed position and a second closed position.
- the jaw members In the open position, the jaw members are oriented apart from each other such that a vessel or other section of tissue may be easily captured between them.
- the first closed position the jaw members are moved or pivoted towards each other such that the inner surfaces are generally parallel to each other. In this configuration, a vessel or other section of tissue held between the jaw members is compressed.
- the jaw members In the second closed position, the jaw members are further moved to the fully closed position such that each of the inner surfaces is in contact with the respective other and the section of tissue held between the jaw members is further compressed.
- a clip applier for applying a surgical clip to a section of tissue within a patient includes an elongate hollow outer body having a proximal end and a distal end. The proximal end is attached to an actuating mechanism having an actuating handle.
- FIG. 3 is a cross-sectional view illustrating the clip applier as depicted in FIG. 2 shown in the first closed position.
- the actuating mechanism 16 may include any device which moves the operating assembly 20, or more preferably the elongated inner member 32, relative to the elongated outer body 12. As shown in FIG. 1, the actuating mechanism 16 may include a main body 48 which is connected to the elongated outer body 12 as previously disclosed.
- a second actuating mechanism 56 may be provided within the elongated inner member 32 to provide a distal or forwardly applied force on the proximal most surgical clip 24. In this way, the second actuating mechanism 56 may be moved distally within the elongated inner member 32 to contact the proximal portion of the clip 24 and force the clip 24 to advance distally within the track 46. When supplied with a plurality of clips 24 the second actuating mechanism 56 advances the proximal most clip 24 distally which in turn advances the plurality of clips 24 such that the distal most clip 24 is advanced or moved forwardly into the guide slots 38 of the jaw members 30.
- the second actuating mechanism 56 includes an elongated push rod 58 which extends substantially coaxially through the inner member 32 and contacts at least one clip 24 at its base or distal end.
- the second actuating mechanism 56 may be provided for moving the push rod relative to the elongated inner member 32.
- This preferred second actuating mechanism 56 which may include a second actuating handle coupled to the main body 48, generally forces the push rod 58 in a linear fashion coaxial with the longitudinal axis 22.
- a biasing spring may be provided to maintain the push rod 58 in either the distally extended position or in a retracted position. It is preferred that the second actuating mechanism 56 be coupled to the first actuating mechanism 16 such that a surgeon may advance a surgical clip 24 into the guide slots 38 when the jaw members 30 are in the first closed position ⁇ FIGs. 3-5).
- This step of compressing the clip 24 may include moving at least one of the shims 60 distally within the outer body 12 such that it is inserted between a guide slot 38 and the clip 24. In this way, the clip 24 is forced inwardly and compressed over the section of tissue 26.
