The intended use of the SOLOASSIST II is a robotic computer driven system whose function is to hold and position a rigid laparoscope / endoscope.
The SOLOASSIST II is indicated for use in minimally invasive interventions where a rigid laparoscope / endoscope is indicated for use. Surgeries, SOLOASSIST II is used, are laparoscopic cholecystectomy, laparoscopic hernia repair, laparoscopic appendectomy, laparoscopic pelvic lymph node dissection, laparoscopically assisted hysterectomy, laparoscopic & thorascopic, decompression fixation, wedge resection, lung biopsy, pleural biopsy, dorsal sympathectomy, pleurodesis, internal mammary artery dissection for coronary artery bypass, coronary artery bypass grafting where endoscopic visualization is indicated and examination of the evacuated cardiac chamber during performance of valve replacement.
The users of the SOLOASSIST II are general surgeons, gynecologists, cardiac surgeon, thoracic surgeon and urologists.
The SOLOASSIST II allows the user to hold and control the movements of a rigid endoscope by using a JOYSTICK, manually by pushing the release button on the Control Panel that is located on the SOLOASSIST II or using the VOICE CONTROL.
The JOYSTICK or the VOICE CONTROL is linked to related connection of the SOLOASSIST II by wire. The JOYSTICK is mounted on the surgical instrument of the surgeon. The movement will be controlled by three motorized axes inside the SOLOASSIST II. The SOLOASSIST II simulates an arm working in several degrees of freedom. The Control Panel of the SOLOASSIST II has 2 buttons and 5 indications. One button is used to set the TROCAR POINT and the other button is used to move the SOLOASSIST manually by pushing the button while moving the arm.
The TENSION SLEEVE and the ENDOSCOPE CLAMP are loosely screwed together. The combination of TENSION SLEEVE and ENDOSCOPE CLAMP are slide over the endoscope and the tension sleeve is tightened so the endoscope can't move out but still can turn. It is important to use the right TENSION SLEEVE for the right diameter of the endoscope. On the rigid endoscope normally there is a camera linked that sends a video to a monitor. Endoscope and camera as well as the monitor are not part of the SOLOASSIST II.
The starting point of the movement for an operation will be saved as the TROCAR POINT. The UNIVERSAL JOINT has to be mounted on the SOLOASSIST II. A mounted UNIVERSAL JOINT can be removed by using the release slider. To define the Trocar point the UNIVERSAL JOINT has a small tracer pin. The tracer pin is placed near the body opening for the endoscope. The TROCAR POINT has to be saved by pushing the button on the control panel of the SOLOASSIST II.
The ENDOSCOPE CLAMP (together with TENSION SLEEVE and Endoscope) is mounted on the UNIVERSAL JOINT, so the SOLOASSIST II is ready for operation.
Based on the trocar point and the desired view of the software of the device calculates the required individual movements of the axes in order to achieve the desired total movement. For example by pushing the left button on the JOYSTICK the image on the monitor moves left, while the SOLOASSIST II is moving to produce the desired view. By pushing the buttons on the JOYSTICK it is possible to move the image on the monitor to the left, right, up, down, zoom in and zoom out.
Additionally it is possible to move the arm of the SOLOASSIST II without the use of the JOYSTICK. Therefore the user has to hold the control panel on the SOLOASSIST II and push the unlocking button (release button) while moving the arm system.
Additionally it is possible to move the arm of the SOLOASSIST II with the use of the VOICE CONTROL. Therefore the user has to put the headset on his head that is connected to the VOICE CONTROL by a Bluetooth-Donqle. The VOICE CONTROL is activated by using the hotword "SOLO". The SOLOASSIST II moves by using predefined Movement Commands.
To allow the surgeon to convert to an open surgery in case of an emergency, the SOLOASSIST II can be completely mounted or removed by a quick fastener.
The provided document is a 510(k) summary for the AKTORmed SOLOASSIST II, including its Voice Control accessory. It describes the device, its intended use, and the performance data submitted to demonstrate substantial equivalence to a predicate device.
However, the document does not contain the level of detail typically found in a clinical study report that would specify "acceptance criteria and the study that proves the device meets the acceptance criteria" in the context of diagnostic accuracy, sensitivity, specificity, or reader performance, as would be expected for a device relying on AI for interpretation.
The SOLOASSIST II is a robotic computer-driven system to hold and position a rigid laparoscope/endoscope. Its "performance" refers to its mechanical and software functionality, not the interpretation of medical images or data. The "acceptance criteria" discussed are largely related to safety, mechanical functionality, electrical safety, electromagnetic compatibility, software validation, and human factors.
Based on the provided text, here's what can be extracted, and where there are gaps regarding the typical understanding of a clinical study for AI-driven image interpretation devices:
1. A table of acceptance criteria and the reported device performance:
The document lists various tests and states that the device "complies" or the test was "performed successfully," implying that the acceptance criteria for those engineering and human factors tests were met. However, it does not present this as a formal table with specific quantitative acceptance criteria or corresponding quantitative results in the way one would for diagnostic performance.

The provided text describes the 510(k) summary for the SOLOASSIST II device. However, it does not contain information about acceptance criteria for particular performance metrics, nor does it detail a study proving the device meets specific performance thresholds in a clinical or human-in-the-loop setting.
The document focuses on non-clinical testing for substantial equivalence, primarily covering:
- Biocompatibility
- Electrical safety and electromagnetic compatibility (EMC)
- Software verification and validation
- Mechanical, acoustic, and bench testing (though these are more about general device robustness and function, not specific performance metrics like speed, accuracy, or image quality that would typically have acceptance criteria for an AI/robotic system controlling an endoscope for image acquisition)
- Cybersecurity risk assessment
- Sterilization
- Human Factors testing (focused on safety and usability, not quantitative performance against acceptance criteria)
- Packaging
Crucially, Section 8.2 states: "No clinical evaluation was conducted for this device." This means there would be no data from a study involving human users or patients to establish performance against acceptance criteria in a real-world or simulated clinical scenario, which is usually where such detailed acceptance criteria for AI-driven assistance systems are measured.
Therefore, I cannot fulfill the request as the necessary information regarding acceptance criteria and a study proving quantitative performance against those criteria (especially for AI assistance) is not present in the provided text. The device, SOLOASSIST II, is described as a "robotic computer driven system" that holds and positions an endoscope, but the performance data presented is entirely non-clinical and focused on safety, usability, and basic functional integrity, not AI-driven performance metrics.
If this were an AI-driven system requiring a clinical or human-in-the-loop study with specific performance acceptance criteria, the provided document would be insufficient.
In summary, based only on the provided text, there is no information to construct the requested table or answer the specific questions about acceptance criteria and performance study details related to an AI-driven component (beyond the general "software verification and validation"). The document explicitly states "No clinical evaluation was conducted for this device."

EndoAssist is indicated for use in general thoracoscopy, general cardiothoracic surgery, general laparoscopy, nasopharyngoscopy, ear endoscopy and sinuscopy, where a rigid laparoscope/endoscope is intended for use.
A few examples of the more common endoscopic surgeries are laparoscopic*
cholecystectomy hernia repair fundoplication splenectomy appendectomy hemicolectomy sympathectomy lymph node dissection hysterectomy gastric banding qastric by pass nephrectomy radical prostatectomy anterior spinal fusion, decompression fixation wedge resection lung biopsy pleural biopsy , internal mammary artery dissection for coronary artery bypass coronary artery bypass grafting where endoscopic visualization is indicated examination of the evacuated cardiac chamber during performance of valve replacement or repair.
- In this context "laparoscopic" is taken to embrace the use of a rigid endoscope in any part of the body
EndoAssist is a head-controlled Endoscopic camera manipulator. It is intended for use in minimally invasive laparoscopic, thoracoscopic, urological, gynecological and cardiac surgery and allows the surgeon directly to control movements of a rigid endoscope by head gestures.
I'm sorry, but without a dedicated study section detailing performance data, acceptance criteria, and ground truth establishment, I cannot fulfill your request for a table of acceptance criteria, device performance, and study information. The provided document is a 510(k) summary for the EndoAssist device, which primarily focuses on device description, intended use, and substantial equivalence to predicate devices, rather than detailed performance study results against specific acceptance criteria.
