NEWDEAL K WIRE is indicated for : - use in Fixation of bone fractures, - bone reconstruction, - as guide pins for insertion of other implants. - The size of the K WIRE should be adapted to the specific indication.

The NEWDEAL K WIRE is available in four different designs, with one or two sharp self-drilling tips either smooth or partially threaded. One part is fixed on a standard surgical power tool equipment for insertion. The NEWDEAL K WIRES are made out of stainless steel within the frame of the standard NF ISO 5832-1, ASTM F138. They are dedicated to fixation of bone fractures, bone reconstruction, as guide pins for insertion of other implants. The range of NEWDEAL K WIRE includes three different diameters 1.0 mm, 1.6 and 2.5 mm and four lengths 70, 100, 150 and 200 mm.

The provided text is a 510(k) summary for the NEWDEAL K WIRE, a Kirschner wire. It details the device's characteristics and its substantial equivalence to predicate devices, but does not contain information about specific acceptance criteria or performance studies as typically found for complex medical devices requiring such validation.

Instead, the document explicitly states:

"SUMMARY OF STUDIES: NEWDEAL K WIRES are stainless steel wires with diameters not smaller than those featured in the predicate device systems Moreover, the NEWDEAL K WIRES conform to the international standard: ISO 5838-1 (1995). Testing, therefore, is not needed to demonstrate that the subject devices are substantially equivalent to other legally marketed Kirschner wires."

This indicates that the device's acceptance was based on its conformance to International Standard ISO 5838-1 (1995) and its material properties (316L stainless steel) and dimensions being comparable to already legally marketed predicate devices (DePuy Kirschner wires and Steinmann pins, and Syntec-Taichung Medical Instruments Kirschner wires and Steinmann pins). The FDA's 510(k) clearance letter confirms this approach, stating the device is "substantially equivalent" to predicate devices.

Therefore, the requested information regarding acceptance criteria, study details, sample sizes, expert involvement, and ground truth establishment cannot be extracted from this document because a dedicated performance study demonstrating the device meets acceptance criteria was deemed unnecessary for this type of medical device due to its substantial equivalence to existing products and adherence to relevant standards.
