The Versaport™ Bladeless Optical Trocar is intended for use in a variety of gynecologic, general, thoracic and urologic endoscopic procedures to create and maintain a port of entry. The trocar may be used with or without visualization for primary and secondary insertions.
The Versaport™ V2 Bladeless Optical Trocar 11mm and 12mm with a transparent cannula is available in standard (100mm), short (70mm) and long (150mm) cannula lengths. The Versaport™ V2 Bladeless Optical Trocar with transparent cannula and obturator allows optical entry for visualization of tissue layers during insertion. The obturator housing contains a scope retention mechanism. The trocar housing contains internal seals to prevent loss of pneumoperitoneum when instruments are inserted into a port or withdrawn completely from a port. The 11mm and 12mm Versaport™ seal system accommodate instruments indicated as 5mm up to 11mm and 12mm respectively. These features are the same as the Versaport™ V2 Bladeless Optical Trocar (5mm) [K112349].
The proposed device (Versaport™ V2 Bladeless Optical Trocar, 11mm and 12mm) has similar design, lengths, and optical features as the predicate devices. The Versaport™ V2 Bladeless Optical Trocar, 11mm and 12mm, includes a transparent cannula, a bladeless obturator with a transparent optical window at the distal end, an obturator housing scope retention mechanism and external interlocking snaps. The scope retention mechanism is located within the obturator housing allowing for secured insertion and retention of an appropriately sized 0° laparoscope for visualization of tissue layers during insertion into the body cavity. There is a 3 way stopcock for insufflation and rapid desufflation. The external interlocking snaps secure the obturator to the cannula. The Versaport™ Bladeless V2 Optical trocar is equivalent to the predicate devices in terms of its intended use and fundamental technology.
The provided submission is a 510(k) Summary of Safety and Effectiveness for a medical device (Versaport™ V2 Bladeless Optical Trocar System). It describes the device, its intended use, and states that in-vitro and in-vivo tests were performed to verify performance and substantial equivalence to predicate devices. However, it does not provide specific acceptance criteria or detailed results of those studies.
Here's a breakdown based on the information available:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not specified in the provided document. | - In Vitro Leak Resistance (verified) |
| - In Vitro Instrument Insertion and Removal Forces (verified) | |
| - In Vitro Snap Feature Retention Force (verified) | |
| - In Vitro Scope Insertion and Retention Forces (verified) | |
| - In Vitro and In Vivo Penetration Force (verified) | |
| - In Vitro and In Vivo Fixation Force (verified) | |
| - In Vivo Visualization of Tissue Layers (verified) |
Note: The document only states that these performance aspects were "verified" and that the device performs "as intended" and is "substantially equivalent" to predicate devices. It does not provide the specific quantitative or qualitative acceptance criteria used for each test, nor the actual measured performance values that demonstrated compliance.
2. Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample sizes: Not specified in the provided document.
- Data provenance: Not specified (e.g., country of origin, retrospective or prospective).
3. 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)
This information is not applicable to this type of device submission. This device is a surgical instrument (trocar), not an imaging or diagnostic device that requires expert interpretation for ground truth.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable as it pertains to methods for resolving discrepancies in expert interpretations, which is not relevant to testing a surgical instrument.
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
This information is not applicable. This device is not an AI-powered diagnostic tool, and therefore, MRMC studies involving human readers or AI assistance are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable. This device is a physical surgical instrument and does not involve algorithms or AI.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
For the performance tests mentioned (e.g., leak resistance, forces, visualization), the "ground truth" would be established by objective measurements and functional requirements defined by engineering specifications and surgical practice standards, rather than expert consensus on diagnostic images or pathology. For example, "leak resistance" would be measured against a defined threshold of acceptable leakage. "Visualization of tissue layers" would be assessed through direct observation during in vivo testing.
8. The sample size for the training set
This information is not applicable. This device is not an AI/ML model that requires a training set.
9. How the ground truth for the training set was established
This information is not applicable. As above, this device does not use a training set.

Missing Information:
Crucially, this 510(k) summary provides a high-level overview of the tests conducted but lacks detailed quantitative results, specific acceptance criteria, and specific methodologies (e.g., sample sizes, experimental setup details) that would typically be found in a full study report. This level of detail is usually present in the full 510(k) submission, but not always in the publicly available summary.

(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
