#### 5. Device Description Summary
21 CFR 807.92(a)(4)
The ENDOFIX EXO is a manually operated surgical device intended to hold endoscopes during general and neurological diagnostic and therapeutic procedures. It emulates an arm which is capable of guiding and positioning an endoscopic camera with several degrees of movement.
lt ensures stable and sensitive positioning of the endoscope and allows the surgeon to work one-handed and/or two-handed. The system provides surgeons with a stable and rocksteady field of vision, even in extreme endoscopic positions. The wide scope of movement provides surgeons with full visibility of the situs. The ENDOFIX exo can be used with both, an endoscope and exoscope.
An integrated DEACTIVATION PUSHBUTTON permits manual movement of the ENDOFIX EXO at the push of a button. In order to reposition a guided endoscopic camera, the ENDOFIX EXO is unlocked by a sterilizable CONTROL at the push of a button. The ENDOFIX EXO is operated by unlocking all 6 axes and subsequent manual positioning using the CONTROL. As soon as the button on the CONTROL is released, all 6 axes are locked again.
Despite its large scope of movement, the ENDOFIX EXO is light-weight and compact and is fastened directly to the OR table by means of a quick-acting clamp. Thus, repositioning with reference to the patient is not necessary even if the OR table is moved in the meantime.
On the rigid endoscope, 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 ENDOFIX EXO.
To allow the surgeon to convert to an open surgery in case of an emergency, the ENDOFIX EXO can be completely mounted or removed by a quick fastener.

During use, the ENDOFIX EXO is covered with a STERILE COVER. The ENDOFIX EXO can be removed from the OR table and stored on the TROLLEY.
#### 6. Intended use/Indications for Use
21 CFR 807.92(a)(5)
The ENDOFIX EXO is indicated for use in interventions where a rigid endoscope is indicated for use. The device is intended to hold and position a rigid endoscope / exoscope during general and neurological diagnostic and therapeutic procedures.
# 7. Indications for Use Comparison
21 CFR 807.92(a)(5)
The indications for use are very similar for both devices have the same intended use, which is the fixation of an endoscope in a position. The ENDOFIX EXO is for use during general and neurological diagnostic and therapeutic procedures. The WalterLorenz Surgical Assist Arm can be used in general and neurological, diagnostic and therapeutic procedures. However, this does not create a new intended use, since the is identical for both devices. For WalterLorenz Surgical Assist Arm Scope Holder the user is a trained medical professional, for ENDOFIX EXO the user is defined as a trained surgeon performing the operation. Both statements mean the same thing, they are just worded differently. The Patient group for the ENDOFIX EXO is all patients, who are suitable within the scope of indications for use. There are no known patient limitations for the WalterLorenz Surgical Assist
Arm Scope Holder. Both devices should only be used in professional healthcare environment.
## 8. Technological Comparison
21 CFR 807.92(a)(6)
Both products have for the most part the same technological characteristics:
Both devices have a permanently installed unlock button, which releases all locks so that the arm can move freely. The unlock button of the ENDOFIX exo is called DEACTIVATION and is located at the distal end of the arm. In contrast, the button of the WalterLorenz Surgical Assist arm is located on the Control Box with User Interface Keypad. However, both devices have a second control panel with an unlock button that is connected to the base unit of the arm via a cable. The control unit of the WalterLorenz Surgical Assist Arm is a sterile, disposable accessory that is supplied separately and can be attached to the distal end of the arm as a release button. The CONTROL of the ENDOFIX EXO is slid over the magnetic bracket of the endoscope clamp and secured from slipping off by a magnetic attraction. When the status LED next to the DEACTIVATION PUSHBUTTON indicates, the CONTROL is ready to operate. This does not happen until the CONTROL is on the magnetic bracket of the endoscope clamp, because there is a sensor in the CONTROL that detects the magnet and only then activates the CONTROL. This increases safety for the patient, as the locks cannot be released if the CONTROL is not on the endoscope clamp. For both devices the Energy Source is Electricity and both do not emit energy. The control units are in the devices. The ENDOFIX exo as well as the WalterLorenz Surgical Assist Arm can be fixed on U.S. table rails. They have no software and do not include biologics, drugs, coatings and additives. For both devices, the sterilizable accessories can be sterilized by steam sterilization and cleaned by wiping disinfection. Regarding the power supply, both devices have the identical input voltage of 100-240 VAC; 50-60Hz and the operating mode is continuous.
Nevertheless, there are few differences of technological characteristics:
The first difference is the mechanism of the two devices. While the WalterLorenz Surgical Assist Arm uses electromechanical brakes in the axes, the ENDOFIX EXO uses electromagnetic brakes to lock movement in all axes. However, there are no safety or effectiveness implications or other safety issues arising from this difference, as the electromagnetic locks have been mechanically tested according to IEC 60601-1:2005 + A1:2012. In addition, the displacement after fixation of the arm has also been tested. From both tests, there are no risks regarding the safety of the arm.

Image /page/6/Picture/0 description: The image shows the Aktormed logo. The logo consists of a blue circle with the letters "am" in white, followed by the word "AKTORmed" in gray. Below the word "AKTORmed" is the phrase "ROBOTIC SURGERY" in a smaller, gray font. The logo is clean and modern, and the colors are professional and trustworthy.
The ENDOFIX EXO is compatible with endoscopes. For the WalterLorenz Surgical Assist Arm Scope Holder, no exact specification of which scopes are compatible could be found. By specifying exactly which scopes are compatible, the ENDOFIX EXO has at least an equivalent level of safety in terms of compatibility with devices as the WalterLorenz Surgical Assist Arm Scope Holder.
The ENDOFIX EXO's safe working load is specified as 1kg, it was even tested with 5kg and no problems occurred. No defined safe working load was found for the WalterLorenz Surgical Assist Arm.
The WalterLorenz Surgical Assist Arm is battery powered. The ENDOFIX EXO, on the other hand, does not have a battery, which means that there is no risk of the battery failing during an operation and the safety of continuous power operation is ensured. However, this means that the ENDOFIX EXO can no longer be moved in the event of a power failure, but it has been assured that the arm will continue to hold the endoscope in a fixed position. In the event that power cannot be restored by reconnection, both the endoscope itself and the device can be safely and quickly removed from the patient using quick-release fasteners as described in the instructions for use.
The weights of the two devices differ significantly. The ENDOFIX EXO weighs 26.5lbs, the WalterLorenz Surgical Assist Arm without the Scope Holder 8lbs. However, the higher weight does not lead to an increased safety risk, as the ENDOFIX EXO is equipped with a counterbalance to compensate for the endoscope and the camera head. In addition, the ENDOFIX EXO is mounted to the operating table so that no weight has to be carried by one person. If the ENDOFIX EXO has to be transported over a long distance, it can be mounted on the trolley provided for this purpose and then only needs to be pushed. A usability test was also conducted with 15 American physicians, where weight was not mentioned negatively.
The output voltage of the two devices varies slightly. The ENDOFIX EXO has an output voltage of 24V DC and the WalterLorenz Surgical Assist Arm has an output voltage of 18V DC. However, the ENDOFIX EXO has been sufficiently tested according to IEC 60601-1 for electrical safety to state that it poses no danger to the user.
The last difference is that the distal unlock button of the WalterLorenz Surgical Assist Arm is a single-use product and comes sterile packed. The control unit of the ENDOFIX EXO, on the other hand, can be used more often, but must be cleaned and sterilized before the first use. The complete validation of the reprocessing and sterilization process confirms that there is no increased risk.
# 9. Non-Clinical and/or Clinical Tests Summary & Conclusions
21 CFR 807.92(b)
The following tests were performed:
- 1. Lifetime test
- 2. Lifetime test CONTROL
- 3. Moving after fixation test
- 4. Usability test
- 5. Package drop test
Nonclinical performance tests of the substantial device are unknown. Therefore own nonclinical performance tests were successfully performed to demonstrate the safety and efficiency of the ENDOFIX EXO.
The non-clinical tests have shown that the ENDOFIX EXO device is as safe and effective as the predicate device. For the WalterLorenz Surgical Assist Arm there are unfortunately no which non-clinical performance tests have been performed. However, since the WalterLorenz Surgical Assist Arm is only a Class 1 device, it can be assumed that all non-clinical performance tests for the ENDOFIX EXO are sufficient to ensure at least equivalent safety.
