Product Overview
Kirwan’s reusable TPR bipolar pencils are available in a variety of lengths to accommodate different microsurgical indications. The pencils can be straight or curved and the pencil tips are offered in beveled, domed, tapered, sharp, blunt or Widestroke™ styles. These pencils are available in 14, 18, 20 and 23 gauge wire sizes.
The insulated wire and sleeve forming the patented coaxial harness assembly of the pencil extends from the rear pins and continues to the distal tip. The area of coagulation is restricted to the space between these two elements permitting discrete coagulation without excessive damage to the peripheral tissue structures. The exterior harness can range in length from very short, for discrete surface coagulation, to 12 inches long for working down through a cannula. The exterior surface of the pencil features a knurled finish providing a non-slip grip. These bipolar pencils also include an indicator on the front end confirming orientation of the tip.
