The EndoWrist Tenaculum Forceps instrument is used with the Intuitive Surgical IS2000 da Vinci S Surgical System and the Intuitive Surgical IS3000 da Vinci Si Surgical System for grasping and manipulation of tissue.

The Endoscopic Instrument Control System is intended to assist in the accurate control of Intuitive Surgical Endoscopic Instruments including rigid endoscopes, blunt and sharp endoscopic dissectors, scissors, scalpels, ultrasonic shears, forceps/pick-ups, needle holders, endoscopic retractors, stabilizers, electrocautery and accessories for endoscopic manipulation of tissue, including grasping, cutting, blunt and sharp dissection, approximation, ligation, electrocautery, suturing, and delivery and placement of microwave and cryogenic ablation probes and accessories, during urologic surgical procedures, general laparoscopic surgical procedures, gynecologic laparoscopic surgical procedures, transoral otolaryngology surgical procedures restricted to benign and malignant tumors classified as T1 and T2, and for benign base of tongue resection procedures, general thoracoscopic surgical procedures, and thoracoscopically assisted cardiotomy procedures. The system can also be employed with adjunctive mediastinotomy to perform coronary anastomosis during cardiac revascularization. The system is indicated for adult and pediatric use (except for transoral otolaryngology surgical procedures). It is intended to be used by trained physicians in an operating room environment in accordance with the representative, specific procedures set forth in the Professional Instructions for Use.

The subject device is a remanufactured 420207 Tenaculum Forceps with a grasping end effector to be used with the Intuitive Surgical da Vinci Endoscopic Instrument Control System (IS 2000 / IS 3000) for grasping and manipulating tissue during and endoscopic procedure. The mechanism of action and principles of operation for the subject device are identical to the predicate device, as there has been no modification to the mechanical design, materials, or dimensions. There are no changes to the claims, intended use, clinical applications, patient population, or method of operation.

While the provided FDA 510(k) clearance letter (K250539) details the clearance of a remanufactured medical device (Remanufactured EndoWrist Tenaculum Forceps), it does not contain information about an AI/ML-driven device or its performance criteria and study results.

The document discusses the substantial equivalence of the remanufactured forceps to a predicate physical device based on identical mechanical design, materials, and intended use. The "non-clinical and/or clinical tests" section refers to:

• Life testing: To verify performance and durability through additional uses.
• Electrical safety evaluation: Per IEC 60601-1.
• Biocompatibility testing: Per ISO 10993-1.
• Reprocessing validation: Per OEM instructions.
• Cybersecurity assessment: Per FDA Guidance on Cybersecurity in Medical Devices.

These tests are standard for remanufactured hardware devices to ensure they meet the same safety and performance standards as the original. They are not related to the type of performance evaluation (e.g., accuracy, sensitivity, specificity, reader studies) typically required for AI/ML-driven medical devices to prove their acceptance criteria.

Therefore, I cannot extract the requested information regarding acceptance criteria and study data for an AI/ML device from this specific document. The document pertains to a traditional physical medical device.
