Some OB/GYN indications for applications include: 1) Cervical Conization. 2) Large Loop Excision of the Transformation Zone (LLETZ) in the diagnosis and treatment of some Cervical Intraepithelial Neoplasias (CIN) and Dysplasias. 3) External Anogenital Lesions. 4) Large Vaginal Intraepithelial Neoplastic (VAIN) Lesions. 5) Bipolar pinpoint, precise coagulation. Pinpoint hemostasis in any field, wet or dry. ## Device Story Quantum 500 Electrosurgical Generator provides high-frequency electrical energy for OB/GYN surgical procedures. Device operates as electrosurgical unit (ESU) for cutting and coagulation. Used in clinical office settings by physicians. Input is electrical power; output is high-frequency current delivered via electrodes to target tissue. Enables precise tissue excision (e.g., LLETZ, conization) and hemostasis. Benefits include controlled tissue removal and bleeding management during gynecological interventions. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Electrosurgical generator providing high-frequency energy for cutting and coagulation. Designed for in-office OB/GYN use. Supports bipolar coagulation. Device is a standalone electrical unit. ## Regulatory Identification A gynecologic electrocautery is a device designed to destroy tissue with high temperatures by tissue contact with an electrically heated probe. It is used to excise cervical lesions, perform biopsies, or treat chronic cervicitis under direct visual observation. This generic type of device may include the following accessories: an electrical generator, a probe, and electrical cables. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
