Acupuncture needles are defined as devices intended to pierce the skin in the practice of acupuncture by qualified practitioners of acupuncture as determined by the States.
The subject of this 510(k) application - the DBC acupuncture needle - is a sterile, single use only acupuncture needle. The DBC acupuncture needle meets the general specifications and criteria for an acupuncture needle and is effective for the practice of acupuncture.
This document is a 510(k) Pre-Market Notification for an acupuncture needle. It does not contain the type of detailed performance criteria and study results typically found for devices that involve AI, image analysis, or complex diagnostic functions.
Here's why the requested information cannot be extracted from the provided text:
- Device Type: Acupuncture needles are relatively simple medical devices. Their primary function is to pierce the skin for acupuncture. The "performance" in this context is about sterility, single-use, and general functionality, not diagnostic accuracy or expert interpretation.
- Lack of AI/Algorithm: The document makes no mention of AI, machine learning, image analysis, or any algorithm. Therefore, concepts like acceptance criteria for AI performance (sensitivity, specificity, AUC), ground truth establishment by experts, training/test sets, or MRMC studies are not applicable.
- Focus of the 510(k): This 510(k) is focused on demonstrating substantial equivalence to predicate devices already on the market. The criteria for acceptance are primarily related to safety (sterility, single-use) and general functionality, not on analytical or clinical performance metrics that would require expert-adjudicated studies.
Therefore, I cannot fulfill your request for the specific points because the provided document does not contain information about:
- A table of acceptance criteria and reported device performance related to AI/diagnostic accuracy.
- Sample sizes for test sets, data provenance, number of experts, or adjudication methods for diagnostic performance.
- Multi-reader, multi-case comparative effectiveness studies.
- Standalone algorithm performance studies.
- Type of ground truth (expert consensus, pathology, etc.) related to diagnostic accuracy.
- Sample size for a training set or how ground truth was established for a training set.
The document's "acceptance criteria" are implied to be meeting the safety and functionality standards for acupuncture needles and demonstrating equivalence to existing devices. The "study" proving this is essentially the information provided in the 510(k) application, highlighting its sterility, single-use nature, and lack of adverse event reports over years of use.

PRE-MARKET NOTIFICATION 510(k) SUMMARY
SEP 23 1996
(As Required by 21 CFR 807.93)
Acupuncture needles are defined as devices intended to pierce the skin in the practice of acupuncture by qualified practitioners of acupuncture as determined by the States.
Acupuncture needles have been used for the general practice of acupuncture in the United States for over 30 years. Since this time, we are not aware of any serious or life threatening accidents involving acupuncture needles.
Acupuncture needles which were sold through commercial interstate distribution prior to May 28, 1976 were non-sterile, reusable acupuncture needles. Acupuncture needles which are currently being marketed through interstate distribution (ie. 1996) offer greater safety since they are sterile, single use only acupuncture needles.
The subject of this 510(k) application - the DBC acupuncture needle - is a sterile, single use only acupuncture needle. The DBC acupuncture needle meets the general specifications and criteria for an acupuncture needle and is effective for the practice of acupuncture.
The DBC brand acupuncture needle was first manufactured in Korea in 1986 and has been imported and sold through interstate commerce in the USA since 1986 under the FDA labeling restrictions of: "Caution: Investigational device limited by U.S. law to investigational use". Since 1986, no accidents or device failure claims have been reported as a result of using the DBC brand acupuncture needle.
In conclusion, based on the information provided with this 510(k) application, the DBC acupuncture needle meets the criteria for 510(k) acceptance. The DBC needle is equivalent to acupuncture needles which were in commercial distribution prior to May 28, 1976. Also, the DBC needle is equivalent to other acupuncture needles which are currently being sold through interstate commerce.
