Indications for Use
The THUNDERBEAT Open Fine Jaw Type X hand instrument is intended to be used for open surgery to cut, seal, coagulate, grasp, and dissect. Seal & Cut mode: The THUNDERBEAT Open Fine Jaw Type X hand instrument when used in combination with the Seal & Cut mode is indicated for open, general surgery (including plastic and reconstructive, etc.) or in any procedure in which cutting, vessel ligation (sealing and cutting), coagulation, grasping, and dissection is performed. The device has been designed to seal and cut vessels (up to and including 7 mm in diameter), tissue bundles, and lymphatics. This mode is also indicated for open ENT procedure in adults (thyroidectomy, parathyroidectomy, parotidectomy, radical neck dissection, and tonsillectomy) for only ligation (sealing and cutting) of vessels, lymphatics and tissue bundles greater than 3 mm away from unintended thermally sensitive structures such as nerves and parathyroid glands. Seal mode: The THUNDERBEAT Open Fine Jaw Type X hand instrument when used in combination with the Seal mode is indicated for open, general surgery (including plastic and reconstructive, etc.) or in any procedure in which vessel sealing, coagulation, grasping is performed. The device has been designed to seal vessels (up to and including 7 mm in diameter), tissue bundles, and lymphatics. This mode is also indicated for open ENT procedure in adults (thyroidectomy, parathyroidectomy, parotidectomy, radical neck dissection, and tonsillectomy) for sealing of vessels, lymphatics and tissue bundles greater than 3 mm away from unintended thermally sensitive structures such as nerves and parathyroid glands. The THUNDERBEAT Open Fine Jaw Type X hand instrument has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.
Device Story
Sterile, single-use electrosurgical/ultrasonic hand instrument; used in open surgery for cutting, sealing, coagulating, grasping, and dissecting. Operates via connection to ESG-400 Electrosurgical Generator and USG-400 Ultrasonic Generator. Employs combined HF bipolar and ultrasonic energy (Seal & Cut mode) or HF bipolar energy only (Seal mode). Physician-operated; used in OR. Provides mechanical grasping and energy delivery to tissue bundles/vessels up to 7mm. Output allows for vessel ligation and tissue division; aids in hemostasis. Benefits include efficient tissue management and reduced surgical time.
Clinical Evidence
No clinical data. Evidence consists of bench testing (ex-vivo porcine vessel burst pressure, temperature-time history) and chronic/acute animal studies (porcine/Beagle dogs) evaluating seal maintenance, thermal spread, and healing progression.
Technological Characteristics
Materials: Polycarbonate, ADC12, PEEK, PTFE, SUS630, SUS304, SUS303, Ti-6Al-4V. Sensing/Actuation: Ultrasonic transducer and HF bipolar electrodes. Energy: Ultrasonic and HF bipolar. Form factor: Hemostat-style hand instrument. Connectivity: Connects to ESG-400/USG-400 generators. Sterilization: Sterile, single-use. Standards: ANSI AAMI ES60601-1, IEC60601-1-2, IEC60601-2-2, ISO 10993, ISO 11135, ISO 11607, ASTM F1980.
Indications for Use
Indicated for open general surgery (including plastic/reconstructive) and open ENT procedures in adults (thyroidectomy, parathyroidectomy, parotidectomy, radical neck dissection, tonsillectomy) for cutting, sealing, coagulating, grasping, and dissecting vessels up to 7mm, tissue bundles, and lymphatics. Contraindicated for tubal sterilization/coagulation. ENT procedures require >3mm distance from thermally sensitive structures (nerves, parathyroid glands).

### Dear Christina Flores:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

# Product Description
THUNDERBEAT Open Fine Jaw Type X hand instrument is intended to be used for open surgery to cut, seal, coagulate, grasp, and dissect.
The THUNDERBEAT Open Fine Jaw Type X hand instrument is provided as a sterile, single use device. The subject device is functional device capable of vessel sealing & cutting, tissue coagulating & cutting, grasping, and dissecting. This device has been designed to seal and cut vessels up to and including 7 mm in diameter, tissue bundles, and lymphatics. This device also has been designed for open ENT procedures in adults.
# Comparison of Technological Characteristics
The basic principle and operational characteristics of the subject device are identical to the predicate device. The proposed THUNDERBEAT Open Fine Jaw Type X Hand Instrument is equivalent to the predicate device in that each device is connected to Surgical Tissue Management System, specifically the ESG-400 Electrosurgical Generator, USG-400 Ultrasonic Generator and THUNDERBEAT Transducer (TD-TB400). Like the predicate device, the subject device activates combined HF Bipolar (FineCoag) output and Ultrasonic output [Seal & Cut mode] simultaneously or only the HF Bipolar output (Seal mode) while grasping vessels, tissue bundles and lymphatics between the Probe and the H electrode in the Grasping section.
{5}------------------------------------------------
In terms of the design concept of the subject device, the differences from the predicate device are as follows:
- Addition of the Radical Neck Dissection indication
- Removal of generator specific information from indications for use
- Adding resin cover (PEEK) on the H electrode
- Changing a material of H electrode in the grasping section and Sheath cover
A side by side comparison of the subject device and the predicate device is provided below.
