A method of forming a combination bipolar scissors and graspers surgical instrument. The method has the steps of: providing a predetermined blade configuration of a bipolar scissors surgical instrument, the predetermined blade configuration having first and second jaw members each having a respective first and second cutting edge and first and second pivoting surfaces; defining a first grasping surface on the first jaw member, the first grasping surface being distal to the cutting edge, the first grasping surface being contained within the confines of the predetermined blade configuration; defining a second grasping surface opposing the first grasping surface on the second jaw member, the second grasping surface being contained within the confines of the predetermined blade configuration; providing a pivot pin pivotally connected to the jaw members wherein at least one jaw member is pivotable in relation to the other jaw member about the pivoting surfaces, the jaw members being capable of pivoting between an open and closed position such that the cutting edges form a scissor and the grasping surfaces form a clamp when the jaw members are in their closed position; and electrically isolating the first jaw member from the second jaw member. A further method is provided in which the cutting edges are distal to the grasping surfaces. Also provided are combination scissors/graspers having blade configurations as illustrated in FIGS.,A-B to,A-B.

Combined bipolar scissor and grasper and method of forming thereof

Open surgery and endoscopic versions of a combined bipolar electrosurgical cutting and grasping instrument where the grasping surfaces are contained within the shape of a standard surgical scissor. This unique arrangement results in a combined scissor and grasper which has the feel of a standard scissor but which allows surgeons to cauterize tissue and vessels while both cutting and grasping thus making the instruments well suited to perform coaptation of vessels. Also disclosed herein, are methods for using the various combined electrosurgical cutting and grasping instruments.
