The SmartXide 50 HS/MS system with its delivery accessories is a medical device indicated for the incision, excision, ablation, vaporization and coagulation of body soft tissues including intraoral tissues, in medical specialties including aesthetic (dermatology and plastic surgery), otolaryngology (ENT), gynaecology, neurosurgery and genitourinary surgery.

SmartXide 50 HS/MS is a surgical CO2 laser with 50W of maximum power in continuous mode. The laser system is produced and sold with an internal predisposition for scanning system (HiScan Surgical for SmartXide HS, MiniScan Plus for SmartXide MS). Laser activation is by footswitch. Overall weight of the laser is 43 kg, and the size is 160 cm x 48 cm x 55 cm (H x W x D). Electrical requirement is 115VAC, 6A, 50-60 Hz, single phase. The wavelength of this laser is 10.600nm. This wavelength is mostly absorbed by water and that makes this laser particularly suitable for soft tissue surgery. The CO2 laser radiation is delivered to the treatment area through the handpiece. The handpiece is attached to the distal end of the articulated arm, which is a permanently mounted laser delivery system of the system. The articulated arm is an optical assembly that delivers free beam laser radiation. It is made up of seven mirrors placed on rotating knuckles: the mechanical accuracy of the articulated arm allows the CO2 laser beam to travel inside it and along its axis however the arm is oriented. The field of action of the articulated arm covers a radius of approximately 80 cm, the transfer efficiency of power is greater than 85%. The loss of 15% is balanced by a suitable calibration of the internal power meter. An air flow is provided by an internal pump in order to avoid dust and particles deposition on the optics during laser operations. Emission parameters are selected on the front panel while emission activation is by the footswitch. The on-off switch and emergency switch are also located on the front panel of the system. A warning light is located on the top cover, close to the control panel. Light ON state indicates that the system is enabled and ready. The CO2 laser microsurgery is done with microspot micromanipulators and scanning systems. The CO2 laser focalized on very little spots (140-250um) and moved by scanning systems is useful to fasten the surgical procedures and limit the thermal damage to the tissues surrounding the ablation. In the SmartXide 50 HS/MS series, the electronic controller of the scanner has been integrated in the laser system with touch screen settings. The scanning systems move the beam on the tissue with controlled velocity and defined patterns to optimize the laser ablation. The high Power Density reached though little spots and typical of the cutting, are thus well controlled by the operator, and the tissue destruction happens in a very quick, delicate and precise way, reducing drastically the surgery time and limiting the lateral thermal damage and the negative phenomenon of carbonisation, with evident advantage for the patient and for the surgeon as well. Both scanning units can be used together with Deka micromanipulator EasySpot. Easyspot has a single ring nut rapid focalization system that allows to focalize the beam to the same focal length of the microscope and fix the position with a mechanical block. In this way the micromanipulator "remembers" the focus position, still allowing eventually the surgeon to defocus the beam from the same ring nut. Thanks to its joystick, it is possible to regulate the mechanical tension and the maximum work field in order to easily control and never "loose" the beam even inside small size faryngoscopes. On top of the joystick Easyspot can mount a remote control specially conceived to command top level scanning systems (HiScan Surgical). It allows the surgeon to have under direct control the more useful electronic scanning functions (rotation and dimension of the figures, scan off-scan on, centering) without moving his eyes from the microscope.

This submission describes a CO2 laser system (Smartxide 50 HS/MS) for soft tissue surgery. The key aspect of this 510(k) is that no acceptance criteria or studies proving performance were conducted or are required for this type of device.

Here's why:

• Predicate Device Equivalence: The safety and effectiveness of the Smartxide 50 HS/MS are established by demonstrating substantial equivalence to previously cleared predicate devices: Lumenis Acupulse30 ST/40 ST (K082809), DEKA Smart CO2 (K072159), and Lumenis UltraPulse Surgitouch (K030147).
• "Nonclinical Performance Data: None" & "Clinical Performance Data: None": The document explicitly states that no nonclinical or clinical performance data was provided or deemed necessary for this 510(k) submission. This is common for devices that are "substantially equivalent" to existing, cleared devices and do not introduce new technology or indications that would necessitate new performance testing.

Therefore, the requested information regarding acceptance criteria, study details, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone studies, and training set information is not applicable to this 510(k) submission.

Summary of Device and Regulatory Context (based on the provided text):

1. Acceptance Criteria & Reported Device Performance: Not applicable. Performance is established through substantial equivalence to predicate devices, not by meeting specific acceptance criteria or through a new performance study.

2. Sample Size & Data Provenance (for test set): Not applicable, as no dedicated performance study using a test set was conducted for this submission.

3. Number of Experts & Qualifications (for ground truth): Not applicable, as no new ground truth determination was required for a performance study.

4. Adjudication Method (for test set): Not applicable.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: Not applicable. No such study was performed or required.

6. Standalone (Algorithm Only) Performance Study: Not applicable. This is a physical medical device (CO2 laser), not an algorithm.

7. Type of Ground Truth Used: Not applicable. Safety and effectiveness are based on the known performance and predicate devices.

8. Sample Size for Training Set: Not applicable, as no machine learning algorithm was developed or tested for this device.

9. How Ground Truth for Training Set was Established: Not applicable.
