Intended Use

Suction Irrigation is indicated for general purpose use as suction/irrigation device to facilitate lavage during laparoscopic surgery and general surgery. The device functions to aid flushing blood and tissue debris from the surgical site.

Device Description

The suction irrigation set, consists of a hand piece equipped with two trumpet style valves, a probe, and connecting lines of tubing, one set designed to attach to a supply of irrigation fluid, and the other designed to attach to an aspiration pump. The valves allow controlled irrigation and aspiration during a surgical procedure. The suction irrigation set is designed to deliver-sterile irrigation fluids to surgical sites during laparoscopic procedures and to evacuate blood. tissue debris, and smoke from the surgical site while the hand piece of the suction irrigator is designed to allow instruments to be introduced through the suction irrigation probe to reach the operative site. The instrument adapter is adjustable to allow a variety of instruments and diameters. It is a single use, disposable device and is sold sterile.

AI/ML Overview

The provided text describes a 510(k) summary for the "Disposable Suction Irrigation" device by Taiwan Surgical Corporation. This document focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study that proves specific acceptance criteria for a novel device. Therefore, a direct mapping to all requested points is not fully possible as the nature of the submission is different from a typical de novo study evaluating a new device's performance against predefined metrics.

However, based on the information provided, I can extract and infer some details:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are implied by the comparison to the predicate device and relevant standards. The "performance" here refers to the device meeting these criteria, often by being "same" as the predicate or passing specific tests.

Acceptance Criteria CategorySpecific Criteria (Implied/Stated)Reported Device Performance
Design/SpecificationDesign DescriptionSame as Predicate device
Length of steel tube (350mm/470mm)Matches Predicate (350mm/470mm), but elsewhere stated as 330mm/450mm for subject device, implying a range is acceptable.
OD of steel tube (5mm)Same as Predicate
PVC soft tube (2900mm)Same as Predicate
Functional PerformanceAnti-vacuity testPassed. "TWSC is the best; the second is Unimax." (Implies better than predicate)
Anti-flat tube testPassed. "No flat tube situation under 400-760 mmHg suction pressure."
Handle button pressure testPassed. "The capability is correspond with product specification." (Implies meeting spec despite being "worse" than something unstated)
BiocompatibilityCytotoxicity TestPassed (following ISO 10993)
Intracutaneous testPassed (following ISO 10993)
Maximization sensitization testPassed (following ISO 10993)
Pyrogen testPassed (following ISO 10993)
SterilizationSterilization Dose (25kGy)Passed, met ISO 11137-2:2012 VD max25 for SAL of 10-9
Safety and EffectivenessSame intended use as predicateSame as Predicate
Same basic technology as predicateSame as Predicate
Achieves same effectivenessConcluded to achieve same effectiveness as predicate
Achieves same safetyConcluded to achieve same safety as predicate

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state sample sizes for tests. It details "bench report" findings, meaning the testing was likely conducted in a lab setting. The provenance of the data is from Taiwan Surgical Corporation's internal testing as part of their 510(k) submission. The type of data is prospective as it involves tests specifically conducted for this submission, not retrospective analysis of past data.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

This information is not provided. For a device like this, the "ground truth" often relates to meeting engineering specifications or established biological safety standards, which are typically assessed by qualified technicians or engineers, rather than clinical experts like radiologists for image-based diagnostics.

4. Adjudication Method for the Test Set

This information is not provided. Adjudication methods are typically relevant for clinical studies where expert consensus is needed to resolve discrepancies, which does not appear to be the primary focus of this type of submission.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices that involve human interpretation of medical images or data. The "Disposable Suction Irrigation" is a surgical tool, and its effectiveness is determined by its functional performance and safety, not by human reader interpretation.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This question is not applicable as the device is a physical surgical tool and not an algorithm or AI.

7. The Type of Ground Truth Used

The "ground truth" for this device's evaluation is primarily based on:

  • Engineering Specifications: Meeting predefined physical dimensions, pressure tolerances, and functional requirements.
  • Established Standards: Adherence to international standards like ISO 10993 for biocompatibility and ISO 11137-2:2012 for sterilization.
  • Predicate Device Comparison: The predicate device (UNIMAX MEDICAL SYSTEM INC., K103509) serves as a benchmark for comparison, implying its established safety and effectiveness forms part of the "ground truth" for demonstrating substantial equivalence.

8. The Sample Size for the Training Set

This information is not applicable. "Training set" refers to data used to train AI models. This device is a physical product, not an AI/software device.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable for the same reason as point 8.

VIII. PERFORMANCE DATA

  • 0 Biocompatibility summary:
    Because the stainless steel and Plasticized Polyvinyl Chloride Compound (PVC) are standard materials for current suction irrigation on the market, they have been thoroughly tested in the past for biocompatibility. The product has passed the biocompatibility test for cytotoxicity, intracutaneous irritation, skin sensitization, and pyrogen.by following ISO 10993.

Therefore, as the contact time for the device is short (<24 hour) with the body and the biocompatibility has proved that device will not cause any cytotoxicity, intracutaneous irritation, skin sensitization, or pyrogen reaction to the body.

● Performance Testing summary:

As the Bench report for Disposable Suction Irrigation concludes that :

(1) Anti-Vacuity test: Unimax >TWSC. Therefore, the anti-vacuity capability of TWSC is the best: the second is Unimax.

(2) Anti-flat tube test : Based on the experiment result, under the suction pressure between 400 and 760 mmHg, there is no flat tube situation.

(3) Handle button pressure test: Based on the handle button pressure test and experiment result. the anti-pressure leak capability of is the worse; but the capability is correspond with product specification.

0 Sterilization and Bio Burden Test Summary:

The sterilization validation of gamma irradiation for Disposable Suction Irrigation was successful and had met the requirements of ISO 11137-2:2012 VD max25 method on substantiation of 25kGy as a sterilization dose. This study therefore supports the multiple batch products to be irradiated at the sterilization dose kGy for a SAL of 10-9.

IX. CONCULSIONS

The Taiwan Surgical Disposable Suction Irrigation has the same intended use and same basic technology as the predicate device, thus is able to achieve same effectiveness and safety as the predicate device.
