FredAssistant: Rafa, Michael Attorney, Agent or FirmInternational ClassA61N 001/30AbstractAn electrosurgical device for laparoscopic use in tissue dissection and coagulation. The device includes a barrel member having a dissection tip at the distal end thereof that is connected to a source of electrical energy. An insulating sheath member surrounds the barrel member. The sheath member is movable between a first position wherein the distal end thereof extends distally beyond the dissection tip and a second position wherein the dissection tip extends distally beyond the distal end portion of the sheath member. The device includes means to flush and vacuum the surgical site. The device also includes pressure relief means to limit the internal pressure within the device.Field of SearchInfrared, visible light, ultraviolet, X-ray or electrical energy applied to body (e.g., iontophoresis, etc.)With tubular injection means inserted into body With means for cutting, scarifying, or vibrating (e.g., ultrasonic, etc.) tissue Material introduced into and removed from body through passage in body inserted means Electrical application Combined cutting-coagulation Cutting Coagulation Applicators With switching or power control Cutting Endoscopic coagulation | |
