7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 1 2000 Introduction Congratulations on your purchase of the CONMED HYFRECATOR® 2000 . The HYFRECATOR® was introduced in 1937 and has become the world leader in office-based electrosurgery. With the latest model, the HYFRECATOR® 2000, CONMED has refined the concept and utilized today’s technology to produce the finest machine of its kind.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 2 2000 Electrosurgery should NEVER be performed in the presence of flammable anesthetics, flammable prep solutions or drapes, oxidizing gases such as Nitrous Oxide (N2O), or in oxygen-enriched environments. The risk of igniting flammable gases or other materials is inherent in electrosurgery and cannot be eliminated by device design.
-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 3 2000 Failure of the unit could result in an unintended increase of output power. When used, the neutral electrode (patient plate) should be reliably attached with the entire surface area in contact with the patient’s body and as close to the operating field as possible. When not in use, the neutral electrode should be disconnected from the Hyfrecator® 2000 to avoid accidental burns.

When the Hyfrecator® 2000 is turned on, the unit automatically “powers up” to the setting last used. 2. POWER ACTIVATION BUTTON When pressed, high frequency energy is emitted from the electrode. Additionally, an audible tone is generated and the active “on” indicator light illuminates. 3.

7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 7 2000 Section 4 - Operation of Your Instrument 1. The Hyfrecator 2000® should be mounted vertically with at least 2" (5cm) clearance around the top and sides of the unit. Approximately 5" (13cm) should be allowed at the bottom of the unit for access to the accessory connections. Adjust the volume to an acceptable level before mounting, because the volume control is at the back of the unit.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 8 2000 • Fulguration: Using either the low or high output terminals, bring the electrode near, but not touching the meat (one to three mm). Use various settings and observe the different degrees of fulguration that can be produced. Short bursts of a spark alternated with short cooling periods are most acceptable to the patient. Continuous application of the spark creates heat that may become intolerable.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 9 2000 Monoterminal (Monopolar) with Dispersive Plate Monoterminal applications with a dispersive plate (See Figure 4) are less common than monoterminal applications without a dispersive plate. Here, the high-frequency current starts from either the high or low output terminals, then travels through an electrode to your patient, where it exits through the dispersive patient plate and returns directly to the unit.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 10 2000 Section 7 - Terminology for Procedural Configuration Desiccation Desiccation comes from the Latin word “desiccare”, meaning to dry. It is a monoterminal without a dispersive plate technique. The electrode either touches, or is inserted into the tissue. The current evaporates the cellular fluids, blanching the area treated (see Figure 6). Typically, the depth of blanching is greater with desiccation than with fulguration.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 11 2000 Fulguration Fulguration comes from the Latin word “fulgur”, meaning an act of lightning. It is a monoterminal without a dispersive plate technique where the electrode is held slightly away from the surface being treated (see figure 8), resulting in sparking to the surface. When delicately fulgurating, you must precisely position the point of the active electrode close to the area being treated or the electrical arc may divert to adjacent tissue areas.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 12 2000 • Application - The two types of coagulation have different effects on tissue. In the first case, the dispersive patient plate deeply draws the current into the tissue. The current efficiently flows through the patient back to the HYFRECATOR® 2000 producing heavy dehydration at the electrode site.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 13 2000 • Lymphangioma: These uncommon tumors may respond to electrodesiccation or fulguration. • Molluscum Contagiosum: These viral lesions resolve quickly with electrodesiccation. • Pyogenic Granuloma: This loose vascular tissue responds well to electrofulguration. • Seborrheic Keratoses: These are perhaps the most common and most cosmetically annoying skin tumors in adults. Their presence is often associated with old age.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 14 2000 • Bowen’s Disease (Squamous Cell Carcinoma in Situ): These lesions respond to the same techniques for basal cell carcinomas. Since these lesions may extend further laterally than they clinically appear, anesthesia should extend one to two centimeters beyond the visible lesions. • Bowenoid Papulosis: Occurring on the genitals, these papules respond to electrofulguration.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 15 2000 Dental and Oral Surgery • Apicoectomy: To prepare for an apicoectomy, insert a fine desiccating needle electrode (Cat. No. 705A) slightly beyond the apex of the tooth, then apply the desiccating current to the infected area. The resulting coagulation reduces capillary bleeding and minimizes the spread of infection during later root resection. • Buccal Gingival Caries: Soft, infected gingival tissue responds to desiccating currents.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 16 2000 Otolaryngology • Adenoid - Hypertrophied Remnants: Coagulate small areas under local anesthesia and repeat the process until the hypertrophied areas are completely destroyed. • Epistaxis: Electrodesiccation is very effective for hemostasis. Anesthetize the areas and carefully identify the vessels. Bring the electrode into direct contact with the ruptured arteriole and use a light current.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 17 2000 Section 9 - Maintenance The HYFRECATOR® 2000 should be tested by qualified service personnel on a periodic basis. CONMED suggests examination of the unit at least every 12 months. NOTE: All internal service should be performed by qualified service personnel only. External Cleaning To keep your instrument performing at its best, external cleaning should be performed on a regular basis.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 18 2000 7-800-6 Footswitching Handpiece The reusable, autoclavable footswitching handpiece is steam sterilizable (see instructions below). This accessory requires the use of a footswitch (Cat. No. 7-900-4) to activate the HYFRECATOR® 2000. Also note that if a footswitch is utilized, a sterile disposable non-switching handpiece (Cat. No. 137657) and a reusable adapter (Cat. No. 670-3) can be used with the HYFRECATOR® 2000.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 19 2000 4. MOBILE PEDESTAL STAND (Cat. No. 7-796-1). Provides the ability to roll the HYFRECATOR® 2000 from one location to another. The stable five-legged steel stand has a durable protective coating. This accessory requires the use of the wall mounting kit, cat. no. 7-796-20. 5. FOOTSWITCH: (Cat. No. 7-900-4). The Footswitch can be used to power activate the HYFRECATOR® 2000. The Footswitch plugs into the switching connector at the base of the unit.
7-900-OM-ENG-.qxd 8/10/98 8:54 AM Page 20 2000 Transportation of the HYFRECATOR® 2000 must be prepaid by the sender. The unit will be returned prepaid to the owner by the same manner of transportation used in shipping the product to the manufacturer. The warranty does not apply to any product, or integral part thereof, that has been altered or serviced by anyone other than the manufacturer.
