Abstract

In various surgical techniques, a bipolar forceps can be used to seal a vessel in two locations such that the vessel can be incised at a location positioned intermediate the two seal locations. The bipolar forceps can include a cutting element which can be configured to incise the vessel. In various embodiments, the cutting element can include a sharp edge which can be moved relative to the vessel. In at least one embodiment, the cutting element can be electrically connected to a source of energy. The bipolar forceps can include first and second electrodes positioned within first and second jaw members, respectively, wherein at least one of the jaw members can include a substantially tapered profile and can be configured to pull the vessel away from the surrounding soft tissue. Such jaw members can include ridges, teeth, and/or a textured outer surface configured to grip the soft tissue and/or vessel.

Claims

1. A surgical instrument for treating soft tissue, comprising:

a flexible shaft;

a housing extending from said flexible shaft;

a conductor in electrical communication with an energy source, said conductor having a contact portion; and

a jaw rotatably connected to said housing, wherein said jaw is configured to be inserted through a working channel of an endoscope, wherein said jaw is selectively rotatable between a first position, an intermediate position, and a second position, wherein said intermediate position is between said first position and said second position, and wherein said jaw includes;

an electrode, wherein said electrode is not in contact with said contact portion when said jaw is in said first position and when said jaw is in said intermediate position, and wherein said electrode is configured to contact said contact portion when said jaw is in said second position such that said electrode is in electrical communication with said conductor to transmit energy to the soft tissue.

2. The surgical instrument of claim 1, wherein said electrode comprises a first electrode, and wherein said surgical instrument further comprises:

a second conductor comprising a second contact portion; and

a second jaw comprising a second electrode, wherein said second electrode is operably configured to contact said second contact portion such that said second electrode is in electrical communication with said second conductor to transmit energy to said first electrode via the soft tissue.

3. A method for processing an instrument for surgery, the method comprising:

obtaining the surgical instrument of claim 1;

sterilizing the surgical instrument; and

storing the surgical instrument in a sterile container.

4. A surgical instrument for treating soft tissue, comprising:

a flexible shaft;

a first jaw;

a second jaw rotatably coupled to said first jaw, wherein said first and second jaws are configured to be inserted through a working channel of an endoscope, wherein said second jaw is selectively rotatable between a first position, an intermediate position, and a second position, and wherein said intermediate position is between said first position and said second position;

a conductor in electrical communication with an energy source, said conductor having a contact portion; and

an electrode, wherein said electrode is not in contact with said contact portion when said second jaw is in said first position and when said second jaw is in said intermediate position, and wherein said electrode is configured to contact said contact portion when said second jaw is in said second position such that said electrode is in electrical communication with said conductor to transmit energy to the soft tissue.

5. The surgical instrument of claim 4, wherein said electrode comprises a second electrode, and wherein said surgical instrument further comprises:

a first conductor comprising a first contact portion; and

a first electrode on said first jaw, wherein said first electrode is configured to operably contact said first contact portion such that said first electrode is in electrical communication with said first conductor to transmit energy to said second electrode via the soft tissue.

6. A method for processing an instrument for surgery, the method comprising:

obtaining the surgical instrument of claim 4;

sterilizing the surgical instrument; and

storing the surgical instrument in a sterile container.
