The Single-use Flexible Rhinolaryngoscope is designed for use with Vathin Display Units, for examination of nasal cavity and upper respiratory tract. For Rhinolaryngoscope models that include a working channel and permit the use of a compatible 3rd party accessory, treatment is also possible.
The Single-use Flexible Rhinolaryngoscope can be connected to the compatible Vathin Display Units and other accessories for examination and treatment of nasal cavity and upper respiratory tract. There are eight subject nasopharyngoscope models: RL-S1800, RL-S1801, RL-E1800, RL-E1801, RL-S1E00, RL-S1E01, RL-E1E00, RL-E1E01. The main differences between product models are in the working channel inner diameter (whether channel is present or not), outer diameter, and rotate function.
This document is a 510(k) summary for a medical device (Single-Use Flexible Rhinolaryngoscope) and primarily focuses on demonstrating substantial equivalence to a predicate device based on technical characteristics and non-clinical testing. It explicitly states that no re-review of the 510(k) submission was done for the administrative correction. Therefore, the provided text does NOT contain information regarding acceptance criteria or a study proving that the device meets acceptance criteria related to AI or algorithm performance.
The document details the device's technical specifications and compares them to a predicate device, along with non-clinical tests (biocompatibility, electrical safety, EMC, and general performance testing) that are standard for medical devices of this type to ensure safety and effectiveness. It does not describe any studies involving algorithms, AI, or human reader performance.
Therefore, I cannot provide the requested information based on the provided text, as it does not address AI/algorithm performance. The information requested (multi-reader multi-case studies, standalone algorithm performance, ground truth establishment, sample sizes for training/test sets in the context of AI) is not present in this regulatory submission document about a rhinolaryngoscope.

Dear Du Jing:
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/cfpmr/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
{2}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
