A sterile, rigid, laparoscopic device, covered with a sheath of electrical insulation, designed to perform through a compatible laparoscopic instrument (e.g., an access port) and to be connected to an electrosurgical diathermy generator when required to provide electrical current, to facilitate blunt dissection (e.g., hernia repair, cholecystectomy, colectomy) between tissue planes accessible via the abdominal cavity. It is a monopolar device typically constructed as a long insulated metal instrument whose distal end is equipped with a stainless steel scissors-like tip of various configurations operated through scissors-like ring handles at the proximal end. This is a single-use device.
