2. Product description The Wi-3 HAL-RAR System is a Bluetooth-enabled, pulsed Doppler, ultrasound system intended to be used for detecting hemorrhoidal arteries, to manually ligate these arteries (HAL), and subsequently carry out a mucopexy of hemorrhoidal tissue prolapse (RAR), if necessary. The hemorrhoidal arteries are located using Doppler ultrasonic technology. The Wi-3 HAL-RAR Unit generates an electrical signal and can be equipped with different probes (see section 14). Product combinations and accessories). Each of these probes is equipped with an ultrasonic sensor converting the electrical signal into an ultrasonic signal. This ultrasonic signal is applied to the rectal area and reflected by solid particles in circulating arterial blood. The ultrasonic sensor receives the reflected signal and converts it into an electrical signal. This electrical signal is then transmitted to the Wi-3 HAL-RAR Unit. The Wi-3 HAL-RAR Unit amplifies and rectifies it and generates a signal that is transmitted as an acoustic output to the audio receiver via the integrated Bluetooth interface. The RAR (Recto Anal Repair) method is used to surgically treat the prolapsing hemorrhoidal tissue, that is typical for the more advanced stages of the disease. RAR involves one or more mucopexies of prolapsing mucosa, carried out after the hemorrhoidal arteries have been ligated. Product name

English 4.2 Overview of Wi-3 HAL-RAR Unit‘s functions a) System check After switching on, the Wi-3 HAL-RAR System automatically performs a system check. During this, also the three indicator LEDs are checked. These flash briefly in red, green and blue. Watch this process to see if any of the LEDs are defective. b) Lighting The Wi-3 HAL-RAR Unit features 3 LEDs lighting the probe. Do not look directly into the light.

Light Emitting Diode (Risk Group 1 according IEC 62471:2006) Do not stare into the beam! c) Volume The volume of the Doppler signal at the audio receiver depends on the volume setting of the Wi-3 HAL-RAR Unit as well as on the volume setting of the applied audio receiver. It is recommended to perform the following steps to adjust the volume:

• • •

Set the volume of Wi-3 HAL-RAR Unit to maximum. Increase the volume of the audio receiver until the desired maximum volume. Now, there is the possibility to switch between the three volume settings low, medium and high directly at the Wi-3 HAL-RAR Unit without having to operate the audio receiver.

How to adjust the volume on the Wi-3 HAL-RAR Unit is further explained in the section 1.19.3. Surgical instruction. d) Counting of the applications The Wi-3 HAL-RAR Unit is limited to 50 separate applications. To count the applications, the unit has an integrated counting mechanism. The number of remaining applications is stored in the probe and in the Wi-3 HALRAR Unit. If the Wi-3 HAL-RAR Unit is switched on, and a valid probe has been detected and there is a connection to the audio receiver, the Wi-3 HAL-RAR Unit assumes that an application is being performed and therefore reduces (after a short Page 13

English waiting period) the number of remaining applications of the probe as well as of the Wi-3 HAL-RAR Unit. As the probes are programmed for only one application, this means that they already become inoperative after counting down one application. The treatment procedure can be performed with one probe from start to finish, as the Wi-3 HALRAR Unit cannot be restarted with a probe that has already been used once. For this reason, never switch off the Wi-3 HAL-RAR Unit before the procedure has been finished. For warnings and messages concerning the number of applications of the Wi-3 HAL-RAR Unit and probes, refer to the following section. e) Displaying the remaining number of applications How to check the number of remaining applications of the Wi-3 HAL-RAR Unit: 1. 2. 3. 4. 5. 6.

Switch off the Wi-3 HAL-RAR Unit. Remove the probe from the Wi-3 HAL-RAR Unit. Press the “Volume“ button. Switch on the Wi-3 HAL-RAR Unit while pressing “Volume“. Wait until the automatic indicator LED check is completed. A repeating blink sequence of the indicator LEDs (in green) follows: a. Each number of flashes of the indicator LED “Battery“ represents 1 application. b. Each number of flashes of the indicator LED “Probe“ represents 10 applications.

Example: Indicator LED “Probe“ flashes 3 times Indicator LED “Battery“ flashes 8 times = This Wi-3 HAL-RAR Unit has 38 applications remaining. If there are no LEDs flashing, it means that the Wi-3 HAL-RAR Unit has expired and cannot be used any more. In this case, use a new Wi-3 HAL-RAR Unit. f) Bluethooth General information: In order to ensure best possible sound quality, the Wi-3 HALRAR Unit, instead of providing integrated speakers, features a Bluetooth interface compatible with many conventional Bluetooth speakers, headphones or other Bluetooth devices. This way, the Doppler signal can be put out to multiple audio devices with premium quality. Please note: Page 14

English If possible, always use the same audio receiver with the same Wi-3 HAL-RAR Unit. Each Bluetooth device has a unique Bluetooth address. Therefore, two optically identical audio receivers are detected as different Bluetooth devices by the Wi-3 HAL-RAR Unit. g) Pairing of the Wi-3 HAL-RAR Unit and the audio receiver General information: Every time, a new combination of audio receiver and Wi-3 HAL-RAR Unit is used for the first time, an initial pairing becomes necessary. During this pairing procedure the Wi-3 HAL-RAR Unit and the Bluetooth audio receiver exchange information required for establishing a connection. At every successful pairing, the Wi-3 HAL-RAR Unit stores the connection details of the audio receiver in a list (subsequently referred to as receiver list). This receiver list can contain up to three audio receivers at a time. Adding a forth receiver leads to deletion of the audio receiver that has not been used for the longest time from the list (if this audio receiver is to be used again, pairing becomes necessary). Optimal conditions for Bluetooth connection: In most cases, it is enough to provide direct sight contact between the Wi-3 HAL-RAR Unit and the audio receiver. However, if this is not enough, the following applies:

• •

• •

Locate and eliminate disturbing sources as far as possible (e.g. switch off Bluetooth function of notebooks, mobile phones or other Bluetooth transmitters). Place the audio receiver that is to be connected, close to the Bluetooth transmitter of the Wi-3 HAL-RAR Unit. The Bluetooth transmitter of the Wi-3 HAL-RAR Unit is located on the bottom of the device opposite of the “Volume” button (refer to picture in section 16). Do not cover the Bluetooth transmitter of the Wi-3 HAL-RAR Unit with your hand. To prevent an accidental connection to any other receiver than the one intended for the Wi-3 HAL-RAR Unit, please ensure that no other audio receiver is near the Wi-3 HAL-RAR Unit.

Audio receiver requirements: The Wi-3 HAL-RAR Unit is compatible with many (however not all) conventional Bluetooth audio receivers (speakers, headphones or other Bluetooth receivers), with the following features:

• •

Profile: HSP or A2DP Bluetooth version: 2.1+EDR (older versions are also supported provided the password has been set to “0000” or “1234“.)

The audio receiver from A.M.I. has already been tested for use with the Wi-3 HALPage 15

English RAR Unit. However, if another (e.g. already existing) audio receiver is to be used, the following recommendations may help to make the right choice:

• • • • • • •

Only use high-quality audio receivers (preferred with A2DP profile), Bluetooth class 2 (transmission capacity max. 2.5mW), Only use audio receivers approved for use in your country, Test function and range thoroughly, Check if other devices are disturbed by the audio receiver, Place audio receiver at the largest possible distance to other switched on devices, Use an EN 60601-1 tested adaptor for audio receivers with external connection.

Please note: In the event the selected audio receiver belongs to a different medical system, check its compatibility with the product information and make sure that there is no interference. The user is responsible for safe application of the selected audio receiver. A.M.I. only guarantees proper function of the Wi-3 HAL-RAR Unit in connection with audio receivers provided by A.M.I. If in doubt, use these audio receivers.

Correct application of ultrasonic equipment According to IEC 60601-2-37, the indices MI, TIS and TIB have been measured (refer to table above). MI (mechanical index) refers to mechanical loads (e.g. cavitation) on tissue by ultra sound. TIS (soft tissue thermal index) and TIB (bone thermal index) refer to ultra sound caused temperature increase on the tissue. Indices MI and TIS that are particularly relevant for hemorrhoidal treatment with the Wi-3 HAL-RAR Unit are very low. TIB is slightly higher (0.73). However, it is only relevant when bones are near the ultrasonic sensor. This is not to be expected during hemorrhoidal treatment using the Wi-3 HAL-RAR Unit. Even though the measured indices MI and TIS are quite low, reasonable application Page 27
