The KARL STORZ suction and irrigation system (consisting of handle and suction/irrigation tubes, cannulae or needles) is intended for use by qualified surgeons to provide suction and/or irrigation function to help flush or remove blood, fluids, and tissue debris from the operation site during general, gynecologic, urologic, and thoracic laparoscopic surgical procedures.

The devices in the KARL STORZ Suction and Irrigation System are manually operated, reusable surgical devices consisting of handle, suction/irrigation tubes, cannulae or needles. The handle is intended to be used in combination with suction/irrigation cannulae and tubing and controls the suction and irrigation. Enabled by the handle with stop cock valve, the regulation of the irrigated quantity of fluids via the tubes, or rather the quantity of aspirated fluid (e.g., blood, fluids, and tissue debris) into or out of the patient is performed. Cannula and needle: Enabled by the pointed distal end, both puncture and injection/extraction cannulae and needles, perform puncturing of target organs or tissues and injecting fluids into operating site i.e. extracting blood or fluids from them. The prerequisite for suction is either a vacuum powered suction wall apparatus or a pump, which serve as impulse for the suction. The proximal end of the tube set is connected to the vacuum or pump. Either a pump is required as impulse for irrigation or the natural force of gravity, i.e., by positioning the flush bag at the appropriate height.

The provided document is an FDA 510(k) Premarket Notification for medical devices, specifically KARL STORZ suction and irrigation systems. This type of submission focuses on demonstrating substantial equivalence to legally marketed predicate devices, primarily through non-clinical performance data and does not typically include studies involving artificial intelligence (AI) or machine learning (ML) components, nor does it present "acceptance criteria" and "device performance" in the context of an AI/ML model's diagnostic or predictive capabilities.

Therefore, the requested information regarding AI/ML-related acceptance criteria and study details (such as sample sizes for test and training sets, expert adjudication methods, MRMC studies, standalone performance, ground truth establishment, etc.) cannot be extracted from this document, as it is not relevant to the type of device and submission described.

The document focuses on:

• Device Description: Manually operated, reusable surgical devices (handle, suction/irrigation tubes, cannulae, needles).
• Intended Use: Suction and/or irrigation to flush or remove blood, fluids, and tissue debris during laparoscopic surgical procedures.
• Basis for Substantial Equivalence: Comparison to predicate KARL STORZ devices (K945059 and K951190) based on technological characteristics and non-clinical performance data.
• Non-Clinical Performance Data Provided:
  • Biocompatibility testing: Compliance with ISO 10993.
  • Reprocessing Validation: Compliance with standards like ANSI/AAMI/ISO 14937, 11138-3, 11607-1, 11737-1, 17664, 17665-1 regarding cleaning and sterilization.
  • Bench Top Performance Testing: Leak Test, Flow Incoming Test, Flow Outgoing Test.

The document explicitly states: "Clinical testing was not required to demonstrate the substantial equivalence to the predicate device. Non-clinical bench testing was sufficient to assess safety and effectiveness and to establish the substantial equivalence of the modifications."

In summary, this document does not contain information about an AI/ML device or its associated performance studies.
