CASTLE SURGICAL LIGHT, MODEL 3000 by GETINGE/CASTLE, INC.

Getinge/Castle, Inc. 3000 Series surgical lamps are designed to provide the high quality lighting required in an operating room environment. The standard configuration shall be a two lamp head system. Two sizes of lamp head will be offered, a 24" diameter and a 32" diameter. There are four major considerations in the design of the surgical lamp systems: Infra-red and Ultra-violet filtration will exceed the specifications as set forth by IEC 601-2-41. Color Representation, as measured by Color Rendering Index and color temperature, will meet or exceed the specifications of IEC 601-2-41. Light delivery, upon failure of one bulb, will continue to be > 70% intensity . Electromagnetic and Bacteriological Neutrality - The product has been designed, and will be tested, to comply with the electromagnetic compatibility requirements of the European Medical Device Directive. The sealed optical unit, the flat smooth surfaces, and the touch-controls provide for an aseptic interface. The lamp head is designed to provide limited interruption of laminar air flow. The lighting systems are supported by specifically designed, steel and aluminum, load bearing drop tubes, yokes, and counterbalance arms. These assemblies are either covered with chemically resistant plastic, or coated with epoxy resin paint. The structures are mechanically connected at pivot points housing fiber optic connection joints. The lamp heads are able to be positioned in virtually any orientation, with no drift once positioned. The light source is an assembly comprised of eight metal halide light bulbs, a dichroic reflective surface to absorb ultra-violet and infra-red radiation, and fiber optic bundle connection points. Color correction is provided by Light Emitting Diode bundles which are mixed with the feed line. These bundles are controlled through an electronic sensor/comparator loop to provide constant, correct color temperature.

AI/ML Overview

The provided text describes a 510(k) submission for a surgical lamp, focusing on its design considerations and regulatory approval. It does not contain information about a study proving the device meets acceptance criteria in the way described in the prompt (e.g., sample size, expert ground truth, MRMC studies, training sets, etc.). The document is a 510(k) summary and approval letter, which typically focuses on demonstrating substantial equivalence to a predicate device based on technical specifications and design rather than clinical performance studies.

Therefore, I cannot fulfill your request for:

A table of acceptance criteria and reported device performance (in the context of clinical studies).
Sample sizes, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, types of ground truth, or training set details.

The document does list design considerations which can be interpreted as acceptance criteria for the device's technical specifications, and states that the design will meet or exceed these specifications, implying performance. However, it does not provide reported device performance results from a study, nor does it detail the methodology of how these performance claims were verified in a study format.

Here's what can be extracted and inferred from the text regarding technical specifications/design goals, which act as acceptance criteria:

Acceptance Criteria (Design Consideration)	Reported Device Performance (as stated or implied)
Infra-red and Ultra-violet filtration will exceed IEC 601-2-41 specifications.	Will exceed the specifications as set forth by IEC 601-2-41. (Implies measured performance meets/exceeds, but no data provided)
Color Representation (CRI and color temperature) will meet or exceed IEC 601-2-41.	Will meet or exceed the specifications of IEC 601-2-41. (Implies measured performance meets/exceeds, but no data provided)
Light delivery, upon failure of one bulb, will continue to be > 70% intensity.	Will continue to be > 70% intensity. (Implies measured performance meets/exceeds, but no data provided)
Electromagnetic Compatibility (EMC) will comply with European Medical Device Directive.	The product has been designed, and will be tested, to comply with EMC requirements. (Implies compliance after testing)
Bacteriological Neutrality (aseptic interface, limited interruption of laminar air flow).	Sealed optical unit, flat smooth surfaces, touch-controls provide for an aseptic interface; designed for limited interruption of laminar air flow. (Design features address this criterion)

Regarding the other points you requested:

Sample size used for the test set and data provenance: Not mentioned.
Number of experts used to establish the ground truth for the test set and qualifications: Not mentioned.
Adjudication method for the test set: Not mentioned.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, effect size: Not mentioned, and highly unlikely for a surgical lamp. MRMC studies are typically for diagnostic imaging devices.
If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable, as this is a medical device (surgical lamp), not an algorithm.
The type of ground truth used: Not applicable in the context of clinical "ground truth." The stated "acceptance criteria" are technical specifications based on industry standards (IEC 601-2-41) and design goals.
The sample size for the training set: Not applicable, as this is a medical device, not a machine learning model requiring a training set.
How the ground truth for the training set was established: Not applicable.

In summary, the provided document is a regulatory approval notice for a medical device (surgical lamp) and details its design considerations. It does not include information about clinical studies with human readers, performance against "ground truth" derived from expert consensus or pathology, or machine learning model training. The "acceptance criteria" are technical specifications that the device's design is stated to meet or exceed, implying compliance through engineering and testing rather than a clinical performance study as typically seen with diagnostic AI.

510 (k) Summary and/or Certification Statement in accordance with Safe 1. Medical Devices Act of 1990:

There are four major considerations in the design of the surgical lamp systems:

Infra-red and Ultra-violet filtration will exceed the specifications as set 1. forth by IEC 601-2-41.
1. Color Representation, as measured by Color Rendering Index and color temperature, will meet or exceed the specifications of IEC 601-2-41.
1. Light delivery, upon failure of one bulb, will continue to be > 70% intensity .
1. Electromagnetic and Bacteriological Neutrality - The product has been designed, and will be tested, to comply with the electromagnetic compatibility requirements of the European Medical Device Directive. The sealed optical unit, the flat smooth surfaces, and the touch-controls provide for an aseptic interface. The lamp head is designed to provide limited interruption of laminar air flow.

The lighting systems are supported by specifically designed, steel and aluminum, load bearing drop tubes, yokes, and counterbalance arms. These assemblies are either covered with chemically resistant plastic, or coated with epoxy resin paint. The structures are mechanically connected at pivot points housing fiber optic connection joints. The lamp heads are able to be positioned in virtually any orientation, with no drift once positioned.
