Circon's Rigid Operative Culdoscopy Accessories are intended to be used with Circon's Rigid Culdoscope and Accessories for viewing pelvic organs endoscopically via a posterior vaginal fornix entry for the purpose of performing diagnostic and operative procedures on the female genital organs. Indications for use are:

Unexplained pelvic pain (acute, chronic)
Menstrual abnormalities
Infertility and sterility
Indefinite pelvic mass
Ectopic pregnancy
Pelvic endometriosis
Polycystic ovaries
Pelvic inflammatory disease (PID)
Pain mapping
Congenital anomalies of the pelvic organs
Lysis of adhesions
Cytology sampling
Biopsy

Device Description

Circon's Rigid Operative Culdoscopy Accessories consist of several tubular stainless steel components. During culdoscopy, light from a high intensity light source is transmitted to a rigid culdoscope by a fiber optic light guide that is detachably connected to a light post on the body of the scope. The light is carried by the illumination fibers to the target. A distal lens focuses an image of the target onto the rod lens train. The image is transmitted to the proximal end of the scope, where it is magnified and focused by an eyepiece ocular. The image may be viewed directly through the evepiece, or the scope may be connected to a video system via a standard endoscopic video coupler. In order to perform operative procedures, the operative cannula of the subject system replaces the smaller diagnostic cannula of the predicate system, and an operative sheath replaces the smaller diagnostic sheath of the predicate system. A channel is formed between the culdoscope and the operative sheath, thereby allowing passage of small instruments for a variety of operative procedures.

AI/ML Overview

The provided text is a 510(k) Summary for "Circon's Rigid Operative Culdoscopy Accessories". The document describes the device, its intended use, and compares it to predicate devices. However, it does not contain information on acceptance criteria, a study proving device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth details.

The 510(k) submission process for this type of device (medical instruments) primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than requiring extensive clinical trials with specific performance metrics and acceptance criteria as might be expected for novel diagnostic algorithms or AI-driven systems.

Therefore, I cannot populate the requested information from the provided text.

Here's the structure of the answer I would provide if the information were available:

1. Table of Acceptance Criteria and Reported Device Performance

Performance Metric	Acceptance Criteria	Reported Device Performance
(e.g., Accuracy, Sensitivity, Specificity, Precision, Image Quality, Functionality)	(e.g., >90% accuracy, Sensitivity > 85%, etc.)	(e.g., 92% accuracy, Sensitivity = 88%)
...	...	...

2. Sample Size and Data Provenance for Test Set

Sample Size for Test Set: [Number]
Data Provenance: [e.g., Country(ies) of origin, Retrospective/Prospective, (if applicable) specific institutions/databases]

3. Number and Qualifications of Experts for Ground Truth (Test Set)

Number of Experts: [Number]
Qualifications of Experts: [e.g., Board-certified Radiologist with X years of experience in Y subspecialty, Pathologist, etc.]

4. Adjudication Method for Test Set

[e.g., 2+1 (two experts, third for tie-breaking), 3+1 (three experts, fourth for tie-breaking), Majority vote, Consensus meeting without formal tie-breaker, None (single expert review)]

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

Was an MRMC study done? [Yes/No]
If Yes:
- Effect size (improvement with AI vs. without AI assistance): [e.g., increase in AUC, sensitivity, specificity, reduction in reading time, etc., with specific values or ranges]

6. Standalone (Algorithm Only) Performance Study

Was a standalone performance study done? [Yes/No]
If Yes:
- Performance metrics: [e.g., Accuracy, Sensitivity, Specificity, AUC, F1-Score, etc., with specific values]

7. Type of Ground Truth Used

[e.g., Expert Consensus (as described above), Histopathology/Pathology, Long-term patient outcomes, Clinical follow-up, Surgical findings, Reference standard device output]

8. Sample Size for Training Set

Sample Size for Training Set: [Number]

9. How Ground Truth for Training Set Was Established

[e.g., Expert annotation (similar to test set, or different process/number of experts), Pathology reports linked to images, Pre-existing clinical labels, etc., describe the process in detail]

1. Name of Device: Rigid Operative Culdoscopy Accessories
  Proprietary/Trade Name: Transvaginal Hydro Laparoscopy (THL") System

Common/Usual Name: Culdoscope and Accessories

Classification: Class II (21 CFR §884.1640)

Classification Name: Culdoscope and Accessories

3) Names of Predicate or Legally Marketed Devices:

Circon's Rigid Operative Culdoscopy Accessories are substantially equivalent to ACMI's Decker Operating Culdoscope and accessories and to Circon's Rigid Culdoscope and Accessories. The Decker devices were legally marketed for the same intended use (i.e., culdoscopy) prior to May 28, 1976, and the Circon devices were cleared under 510(k) #K980972 on June 12, 1998.

4) Description of Device:

6) Comparison of Technological Characteristics:

●

Circon's Rigid Operative Culdoscopy Accessories are substantially equivalent' to the ACMI Decker Operating Culdoscope and to the Circon Rigid Culdoscopes and Accessories. Circon's operative accessories employ the same design considerations and operating pripines as the legally marketed predicate devices, and each can be cleaned, sterilized and reused. Any differences between these devices do not raise new questions regarding safety or effectiveness.

'The term, "substantially equivalent," is intended to reflect a determination of substantial equivalence under the Federal Food, Drug, and Cosmetic Act, and relates to the fact that the product can be marketed without premarket approval or reclassification. Such a determination is not intended to have any bearing on matters relating to patents.
