Intended Use

The Space-OR Retractor is a flexible internal retractor intended for the retraction of organs and tissues during abdominal surgery.

Device Description

The Space-OR is a flexible retractor which can be formed by the user into the desired shape for retraction of organs or tissues during abdominal surgery. The Space-OR can be left in position for a complete abdominal procedure.

In the relaxed position, the Space-OR is malleable and can be placed along a wound edge or in the abdominal cavity. The device can be shaped around the desired organs forming an optimum retractor. The Space-OR includes a connector for wall vacuum. When vacuum is pulled, the device then solidifies, staying in the position formed by the user. The Space-OR will maintain its shape, retracting the desired organs or areas until the clamp is released.

The vacuum applied to the Space-OR must be greater than 150 mmHg for the device to become solid. Once applied, the evacuation tubing is clamped and the vacuum pump removed. The device may be maintained in place for the duration of the surgery. If desired, the user can release the clamp on the vacuum, reposition the Space-OR and re-apply the vacuum.

AI/ML Overview

The provided text describes a 510(k) summary for the Advanced Surgical Concepts Space-OR Retractor, a manual surgical instrument. It is exempt from providing detailed performance testing results typically seen in AI/ML device submissions. Therefore, many of the requested details related to acceptance criteria, ground truth, and expert evaluation are not available in this document.

However, based on the information provided, here's a summary of the available "acceptance criteria" and "study" information:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Implied)Reported Device Performance
Maintain solid state at >150 mmHg vacuum"The vacuum applied to the Space-OR must be greater than 150 mmHg for the device to become solid. Once applied, the evacuation tubing is clamped and the vacuum pump removed. The device may be maintained in place for the duration of the surgery."
Biocompatibility"The patient-contacting materials used in the Space-OR have been subjected to and passed biocompatibility testing according to ISO-10993."
Function as intended in vivo (animal model)"Animal testing has been performed showing that the Space-OR functions as intended."
No adverse effects/complications in clinical use"Additionally, the Space-OR has been in commercial distribution in Europe for over nine years with no complications or adverse effects."

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

  • Animal Testing: The document states "Animal testing has been performed," but does not specify the number of animals or the exact study design.
  • Clinical Use in Europe: "in commercial distribution in Europe for over nine years." No specific "test set" size is provided; this refers to real-world usage. The data provenance is described as clinical use in Europe, which is retrospective.

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

Not applicable. This device is a manual surgical instrument, not an AI/ML imaging device requiring expert ground truth for image interpretation. The "ground truth" for its performance is its physical function and clinical safety.

4. Adjudication Method for the Test Set

Not applicable. No expert review leading to adjudication is mentioned for this type of device.

5. 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. This is not an AI/ML device, and no MRMC study information is provided.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is not an AI/ML device.

7. The Type of Ground Truth Used

  • Bench Testing: The ability to "become solid" at a specified vacuum level would have been verified through bench testing.
  • Biocompatibility Testing: Performed per ISO-10993 standards.
  • Functionality: Assessed in animal models.
  • Safety/Effectiveness: Observed via "no complications or adverse effects" during nine years of commercial distribution in Europe.

8. The Sample Size for the Training Set

Not applicable. This is not an AI/ML device, so there is no "training set."

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

Not applicable. There is no training set for this device.

4. DEVICE DESCRIPTION

The Space-OR is a flexible retractor which can be formed by the user into the desired shape for retraction of organs or tissues during abdominal surgery. The Space-OR can be left in position for a complete abdominal procedure.

In the relaxed position, the Space-OR is malleable and can be placed along a wound edge or in the abdominal cavity. The device can be shaped around the desired organs forming an optimum retractor. The Space-OR includes a connector for wall vacuum. When vacuum is pulled, the device then solidifies, staying in the position formed by the user. The Space-OR will maintain its shape, retracting the desired organs or areas until the clamp is released.

{1}------------------------------------------------

The vacuum applied to the Space-OR must be greater than 150 mmHg for the device to become solid. Once applied, the evacuation tubing is clamped and the vacuum pump removed. The device may be maintained in place for the duration of the surgery. If desired, the user can release the clamp on the vacuum, reposition the Space-OR and re-apply the vacuum.

INTENDED USE પં

The Space-OR is a flexible internal retractor intended for retraction of organs and tissues during abdominal surgery.

TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.

The Space-OR Retractor is substantially equivalent to the Sklar Surgical Instruments Meyerding Retractor and the ALM Self Retaining Retractor, and the Lone Star Products Retractor System.

The Space-OR is identical in intended use to the Lone Star and Sklar mechanical retractors in that they are all intended to be positioned over target organs or tissues for retraction during abdominal surgery.

The technological characteristics of the Space-OR are similar to the substantially equivalent devices. They are all designed to be positioned over the target area in the abdominal cavity and function as a retractor to hold back organs and/or tissues from the operative area. Metal is used in the substantially equivalent devices whereas the proposed Space-OR is made of PVC. This difference does not adversely affect safety or effectiveness since the PVC has been subjected to and has passed biocompatibility testing. Additionally, the Space-OR has been tested in pigs and has been used clinically in Europe for several years with no adverse effects or complications.

PERFORMANCE TESTING 7.

The patient-contacting materials used in the Space-OR have been subjected to and passed biocompatibility testing according to ISO-10993. Animal testing has been performed showing that the Space-OR functions as intended. Additionally, the Space-OR has been in commercial distribution in Europe for over nine years with no complications or adverse effects.
