SURGICAL INSTRUMENT

摘要

A method of using electrosurgical instrument for removal of tissue from a patient. The electrosurgical instrument includes a pair of lever members each of which having an associated end effector associated. One of the end effectors includes a cutting element forming a loop on the end of the end effector. The cutting element is also configured to receive electrical energy from an electrical energy source. The other of the end effectors includes a pad that can be brought into a position generally opposing the cutting element during relative movement of the end effectors toward one another. When electrical energy is discharged from the cutting element and the end effectors moved toward one another, dissection and cauterization of tissue from a patient is facilitated.

1. A method of dissecting tissue from a patient utilizing an electrosurgical instrument, the electrosurgical instrument having a pair of lever members with an end effector associated with each of the lever members and supported by the lever members for relative movement in a direction toward one another, one of the end effectors including a cutting element that is configured to receive electrical energy from an electrical energy source, the cutting element forming a loop having a central opening on the end of the end effector, the method comprising:
positioning the loop on one lateral side of the tissue to be removed and positioning the other of the end effectors on an opposing lateral side of the tissue to be removed; causing relative movement of the end effectors toward each other; providing electrosurgical energy to the cutting portion and discharging the electrosurgical energy through the cutting element to the tissue to be removed ; dissecting and cauterizing the tissue; passing the dissected tissue through the opening of the loop; and removing the dissected tissue from the patient.
