AnQing Medical Flexible Choledochoscope has been designed to be used with the video processor, monitor, endotherapy accessories and other ancillary equipment for endoscopic diagnosis and treatment within the bile duct. The Flexible Choledochoscope is designed for use in adults.

The Flexible Choledochoscope (Model: CS50H-20EU, CS50H-20US) is a sterile single-use endoscope which is used with the video processor (Model: EOS-H-01. FDA cleared #K211169) produced by AnQing for providing endoscopic imaging within the bile duct for the purpose of diagnosis and treatment. The 2 proposed models are identical except the deflection versions, which is opposite from each other (EU version or US version). The Flexible Choledochoscope is a single-use endoscope, which consists of Handle, Insertion Section, Distal Tip, and Endoscope Connector. The handle includes a deflection lever, a lever lock, an aspiration button, an aspiration connector, a push button for picture taking/video recording and a Luer port for insertion of accessory devices and irrigation to the working channel. The insertion contains one working channel and wiring to transmit the image signals to the Video Processor. The distal bending section of the insertion section is controlled by the user via the deflection lever on the handle. The distal end of the insertion section contains a CMOS sensor for capturing image and transmitting it to the Video Processor, LEDs for illumination, and the distal opening of the working channel. The endoscope connector connects the endoscope handle to the video processor, which provides power and processes video signals from the endoscope.

The provided document is a 510(k) Premarket Notification from the FDA, specifically concerning a Flexible Choledochoscope. This type of document is for a medical device that does not rely on complex algorithms or AI for its primary function. Therefore, the concepts of "AI algorithm," "acceptance criteria for an AI model," "training dataset," "test set," "ground truth establishment," "MRMC studies," and "standalone performance" as they relate to AI are not applicable to this submission.

The acceptance criteria and performance data provided in this document are entirely related to the physical and functional characteristics of the choledochoscope itself, not an AI component.

Here's an analysis of the document in relation to the questions asked, noting where the questions are not applicable due to the nature of the device:

Acceptance Criteria and Device Performance (Non-AI Device)

Since this is a physical medical device (a choledochoscope), the "acceptance criteria" are related to its physical properties, safety standards, and functional performance compared to a predicate device.

1. A table of acceptance criteria and the reported device performance

The document presents a comparison table between the subject device (Flexible Choledochoscope, Models CS50H-20EU, CS50H-20US) and its predicate device (Olympus CHF TYPE V), showing "acceptance criteria" as functional and physical similarities and differences. The "reported device performance" is essentially that the subject device meets or is comparable to the predicate device in these aspects, and where there are differences, non-clinical tests were conducted to demonstrate equivalence without raising new safety/effectiveness concerns.
