The OpClear® System consists of a reusable control unit and a range of disposable sterile single-use accessories intended to remove visual obstructions such as condensation, blood and other tissue particulates from the distal lens of a laparoscope during surgery and therefore maintaining a clear image of the surgical site.
OpClear® System is a laparoscopic lens cleaning device which is intended to be used during any laparoscopic surgical procedure where there is a potential for contamination of the distal lens. Consisting of a reusable control unit and a range of sterile, invasive, single use disposables, it is intended to maintain surgical vision by removing contaminants such as condensation, blood, peritoneal fluid, smoke, fat and tissue smears that have contaminated the distal lens of the laparoscope during surgical procedures.
OpClear® System is composed of a control unit and a range of disposable accessories as shown below.
This document describes the OpClear® System, a laparoscopic lens cleaning device, and its FDA 510(k) submission (K171637). The information provided focuses on device description, indications for use, operating principles, and a summary of non-clinical testing. It does not contain a detailed study with specific acceptance criteria, reported device performance metrics, or information on sample sizes, expert ground truth, adjudication methods, or MRMC studies.
Therefore, many of the requested elements cannot be extracted from the provided text.
Based on the available text:
-
A table of acceptance criteria and the reported device performance
The document mentions that "Performance validation has been performed following improvement in the operating parameters for the Device" but does not provide a table of acceptance criteria or specific reported device performance metrics. -
Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not provided. The document refers to "a simulated human abdominal cavity environment" for testing.
- Data Provenance: The testing described is "non-clinical testing" conducted in a "simulated human abdominal cavity environment" in a "laboratory." This implies the data is prospective from an in vitro or benchtop study, not human subject data. The submitter is UK-based (Cipher Surgical Limited, Coventry, UK), suggesting the laboratory testing was likely conducted in the UK.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable/Not provided. The ground truth for the non-clinical testing appears to be based on the validated "simulated human abdominal cavity environment" and optimizing device parameters, not expert consensus on diagnostic images. -
Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable/Not provided, as the testing was non-clinical and did not involve human interpretation or diagnostic adjudication. -
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. The OpClear® System is a physical medical device (laparoscopic lens cleaning device), not an AI-powered diagnostic or assistive tool. Its function is to maintain clear vision during surgery, reducing the need for human readers (surgeons) to interrupt their work for cleaning. The document does not describe any MRMC study or AI components. -
If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is a physical device, not an algorithm. Its performance is inherent to its mechanical and fluid delivery functions as operated by a surgeon. -
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The ground truth for the "Performance validation" in the non-clinical testing was based on the "suitability" of the "simulated human abdominal cavity environment...as a simulation of the operating environment for the device." This implies an engineered definition of cleanliness or obstruction removal within the simulated environment. -
The sample size for the training set
Not applicable. The OpClear® System is a physical device, not a machine learning algorithm that requires a "training set." -
How the ground truth for the training set was established
Not applicable, as there is no training set for this physical device.

OpClear® System is for professional use in a theatre environment, during all Laparoscopic procedures. It is suitable for use in all adult patients who have been selected by their physician / surgeon for laparoscopic surgery using 10mm laparoscopes of a compatible length / type.
{5}------------------------------------------------
Indications for use:
The OpClear® System consists of a reusable control unit and a range of disposable sterile single-use accessories intended to remove visual obstructions such as condensation, blood and other tissue particulates from the distal lens of a laparoscope during surgery and therefore maintaining a clear image of the surgical site.
Operating Principle:
During MIS, the laparoscope lens window is the surgeon's eyes and it can become covered in body fluids: peritoneal fluid, blood, and fat as well as tissue particulate or condensation impairing the surgeon's vision (via an external monitor/screen). Traditionally, cleaning the lens window of the laparoscope as a result of soiling required its removal of the laparoscope from the patient's abdomen which results in increased risk of infection, increased surgical duration, compromised surgeon workflow and compromised vision.
The OpClear® System uses carefully controlled timed flows of CO2 and saline delivered to the lens surface to maintain a clear vision and remove/reduce the need to remove the laparoscope during a surgical procedure.
OpClear® Control Unit
The OpClear® Control Unit is a mains powered medical device which is connected to the electrical mains supply and to either a CO2 bottle or CO2 wall supply.
It supplies, on demand, CO2 to the distal lens of the laparoscope (via the OpClear® Disposable) and CO2 to operate the plunger of the sterile disposable wash cartridge.
The surgeon makes the selection of either demist function or wash function by operating a pneumatic foot switch control as and when required. Full details of the operation of the device are given in the instructions for use.
{6}------------------------------------------------
OpClear® Disposable
The OpClear® Disposable is a sterile, invasive, single use accessory to the OpClear® control unit, which is fitted to a compatible laparoscope immediately prior to the start of the surgical procedure. The disposable directs the CO2 and saline directly to the distal lens of the laparoscope in response to the surgeon's requirements. The CO2 supply from the control unit is used to propel the plunger of the refillable 0.9% saline cartridge (which forms part of the disposable) and deliver the saline at the desired time and position.
Materials:
OpClear® Control Unit
The OpClear® control unit consists of a painted aluminium enclosure containing a power supply, control circuitry and an anodised aluminium manifold which supplies CO2.
OpClear® Disposable
The OpClear® disposable consists of a co-polyester moulding which is bonded to the extruded PVC CO2 and saline supply tubes. The wash cartridge is formed of a polypropylene barrel with a polyethylene piston.
The co-polyester moulding is the only invasive part of the disposable.

Summary of Non Clinical Testing:
The Device has been developed in the laboratory using a simulated human abdominal cavity environment which includes the ability to set pressure, atmospheric composition (CO2 rather than air), temperature, humidity and operational lighting environment. The suitability of this test chamber (as a simulation of the operating environment for the device) has been validated. The performance of OpClear® System has been optimised using this bench model. Performance validation has been performed following improvement in the operating parameters for the Device.
