The D8200 Bipolar Forceps are used during ophthalmic procedures, coagulating extraocular tissue by pinching it between the forcep tips. The D8201 Bipolar Eraser is also used during surgery for cauterization of extraocular vessels, while the D8203 Bipolar Intraocular Eraser is used in posterior ophthalmic surgical procedures to cauterize vessels internal to the eye. ## Device Story Storz Ophthalmic Bipolar Cautery devices (D8200 forceps, D8201 eraser, D8203 intraocular eraser) function as accessories to Storz DAISY, Protege, and PREMIERE Ophthalmic Microsurgical Systems. Devices connect to the microsurgical system via D8202/D8204 bipolar cords using Lemo locking connectors. During ophthalmic surgery, the surgeon uses the instruments to deliver radiofrequency electric current to tissue; forceps coagulate extraocular tissue by pinching; erasers cauterize extraocular or intraocular vessels. The system provides controlled hemostasis, benefiting the patient by reducing bleeding during surgical procedures. Devices are reusable and operated by ophthalmic surgeons in a clinical/surgical setting. ## Clinical Evidence No clinical data. Bench testing only. ## Technological Characteristics Reusable bipolar cautery instruments (forceps, erasers) and cords. Materials: surgical grade stainless steel, spring steel, liquid crystal polymer insulation, thermoplastic rubber cord insulation. Energy source: radiofrequency electric current provided by compatible microsurgical systems. Connectivity: Lemo locking connectors. Form factor: 20-gauge intraocular tips. Sterilization: not provided sterile. ## Regulatory Identification A radiofrequency electrosurgical cautery apparatus is an AC-powered or battery-powered device intended for use during ocular surgery to coagulate tissue or arrest bleeding by a high frequency electric current. ## Predicate Devices - Kirwan Ophthalmic Bipolar Forceps, Bipolar Pencils, and Bipolar Cord (Kirwan Surgical Products, Inc.) - Mentor WET-FIELD Bipolar Forceps and Bipolar Hemostatic Erasers (Mentor O & O, Inc.) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Swearingen Regulatory Affairs Associate Date Prepared: May 4, 1995 Proprietary Name: Storz Ophthalmic Bipolar Cautery Instruments and Bipolar Cords Common/Usual Name: Ophthalmic Bipolar Cautery Devices Classification Name: Apparatus, Cautery, Radiofrequency, AC powered; 86(HQR) Device Description: Storz D8200 series Ophthalmic Bipolar Cautery devices are accessories to Storz DAISY®, Protege®, and PREMIERE® Ophthalmic Microsurgical Systems. The D8200 is a reusable bipolar forceps, D8201 is a reusable bipolar eraser, and the D8203 is a reusable bipolar intraocular eraser. The D8202 bipolar cord is used to connect the three cautery instruments to the Storz Protege® and PREMIERE® Microsurgical Systems. All three instruments and both cords have Lemo™ locking connectors. The D8200 forceps are composed of surgical grade stainless steel; the D8201 and D8203 erasers are composed of surgical grade stainless steel and spring steel, and liquid crystal polymer insulation. These materials raise no questions of biocompatibility. Intended Use: The Storz Ophthalmic Bipolar Cautery devices are used to control bleeding during ophthalmic surgical procedures using radiofrequency electric current. The D8200 Bipolar Forceps are used during ophthalmic procedures, coagulating extraocular tissue by pinching it between the forcep tips. The D8201 Bipolar Eraser is also used during surgery for cauterization of extraocular vessels, while the D8203 Bipolar Intraocular Eraser is used in posterior ophthalmic surgical procedures to cauterize vessels internal to the eye.
