Ultrasound exceeds any manual cleaning in effectiveness!
Through ultrasonic cavitation not easily accessible areas on sensitive instruments are advantageously reached.
Mechanical damages like scratches are avoided („electronic brushing“).

Moving and rinsing additionally intensify the cleaning effect! 
The new TRISON Twist is the first to move all instrument axes of up to 4 robotic instruments separately – for an improved ultrasonic effect. It is available as an „Si“ or „Xi“ version, in respect to the instrument types. A new ergonomic innovation is the new pivot mounted arm TRISON Lift. It allows a simple connection of the instruments and a comfortable lowering of the TRISON Twist into the ultrasonic tank. The TRISON cleaning concept is completed by an alternating suction and pressure rinsing of every instrument lumen in combination with an individual examination.

TRISON – the modules

Moving device with ergonomic pivot mounted arm – TRISON Twist and Lift

The heart of the TRISON is the innovative moving ­device TRISON Twist for up to four robotic instruments. Special sprung actuators engage with the bottom of the instruments and move them during sonication. The surgical working tools are rotated and manipulated at their tips for all-over ultrasonic effect. Integrated friction clutches prevent damage to filigree cables and drive rollers.

The cleaning process is also supported by the permanent internal rinsing of the instruments. To allow this, the instruments are connected with hoses to the rinsing cycle of the TRISON Base control unit. The removed soiling is guided directly into the exchangeable filter, rather than back into the bath fluid. Various series of experiments with actually contaminated instruments and with standardised test contamination confirm the effectiveness of the new TRISON cleaning concept.

Control unit – the base

During sonication, each instrument is individually released for rinsing and checked for flow-through (patent DE 20 2006 020 523). Non-rinsable instruments are reliably identified and displayed on the touch screen at the end of the process. The integrated process control for determination, classification and clear indication of successful rinsability for each instrument ensure a higher safety level during treatment.

The TRISON Twist allows the fixation of up to four ­robotic instruments by means of a simple push-on mechanism – no additional basket is required. Connection to the rinsing cycle is made with one double Luer connector per instrument.
The special TRISON Rack basket allows up to eight MIS instruments to be connected for rinsing, using the reliable SONOMIC adapter.
Connection to the TRISON Base control unit is performed quickly and without risk of mix-up by using two multi-hose connectors.

TRISON has been specially developed for robotic instruments. With the use of suitable accessories, however, MIS instruments and standard instruments can also be effectively cleaned. In order to best meet the various cleaning requirements, a cleaning program is available for each instrument type.

TRISON has a temperature sensor which, prior to each cleaning cycle, tests whether the temperature of the bath fluid is within the permitted range. To prevent protein coagulation, a warning message appears at temperatures of about 45 °C. If the bath fluid temperature is too low (< 16 °C), a warning message is also given.

For quality verification, TRISON provides two inter­faces. A USB interface allows simple and flexible data transfers using a USB stick. The ethernet ­inter­face allows link-up to a central sterile service management software or similar. Logging includes: cleaning mode, bath temperature, result of rinsing examination, etc.

TRISON Base

Ultrasonic oscillating bath

The TRISON ultrasonic oscillating bath has been specially dimensioned for extremely long robotic instruments. Thanks to the high-performance ultrasonic oscillating systems on the bottom and sides, drive adapters, instrument shafts and working tools at their tips are optimally reached by ultrasound and possible acoustic shadows are avoided. The TRISON ultrasound generator is equipped with the SweepTec automatic frequency control system in order to minimise standing waves and to guarantee a homogeneous ultrasonic intensity distribution. In a cleaning program designed in consultation with the manufacturer, robotic instruments are first soaked for approx. 30 min. in order to partially dissolve or break down organic residues. In the subsequent alternating suction and pressure rinsing process with ultrasound support, the ­control housing and shaft of each instrument is rinsed and tested for flow-through. In this way, even stubborn contamination is reliably stripped off and removed.

Technical data

• PZT oscillating systems: 24 (frequency 35 kHz) 
• operating volume: 42 l

Lid

By means of the appropriate lid the cleaning liquid is protected from contamination, and annoying perceived noise emission during the operation is reduced. During removal of the cleaned parts the lid can be vertically placed at the tank border thanks to its ergonomic design.

The lid is universally suitable for all TRISON treatments and is available in a right and left version.

  TRISON 4000: Advantages for the user

   Interview about the use and possibilities of the TRISON 4000

Specialty: powerful, essential and valued cleansing systems

Pre-cleaning complex robotic instruments

‘We are a medium-size German company specialising in ultrasonic equipment for cleaning, including pre-cleaning of medical instruments from different medical fields,’ explained Florian Knuth, Sales Director for the Medical Division of the firm Bandelin, during an interview with Ralf Mateblowski, of European Hospital 

‘We’ve produced and distributed dif-ferent types of ultrasonic equipment for pre-cleaning of medical instru-ments for a number of decades,’ Knuth added. ‘This ranges from one litre devices for smaller medical practices to large, built-in devices for the Central Sterile Services Department (CSSD). Additionally, we offer specialist devices, such as those required for MIS instruments or robotic instruments.’
Asked about the development and more general use of robotassisted surgery, Knuth said the advantages are obvious. ‘More precision for complex interventions and therefore a clear reduction in the number of surgical errors. However, these hightech instruments with long lumen, various control wires, detailed cutting tools and complex design also require special handling. The manufacturer supplies detailed instructions for manual pre-cleaning. This involves rinsing, brushing, and moving the instruments in many individual steps. This procedure is very time-consuming.

Knuth: ‘Increasingly complex surgical instruments require innovative technical solutions for adequate preparation. Our focus is on achieving optimum safety during preparation using validated proce-dures, whilst simultaneously saving resources.To avoid this,we have integrated a control function, which monitors the device components and correct procedure throughout the process. We have also integrated a rinse control function, meaning that, should one or several instruments still be blocked after treatment, this is indicated on a large display. This function provides additional security to ensure the correct condition of the instruments for further treatment.’

EH: Documentation of processes is necessary from a regulatory perspective, as well as for quality management guidelines. Does the Trison 4000 offer this?
Knuth: ‘Documentation of all individual steps may be considered time-consuming, but it  provides user  safety. Comprehensive pro-cess documentation guards against potential situations where users may have to provide explanations, meaning that, if something was not documented, it was not done.
‘All users should safeguard against this, which is why the Trison 4000 generates a protocol of the last cycle after each treatment. This protocol documents all relevant parameters and can be securely, digitally archived via a USB interface or through integration into the net-work.’

With all these advantages, there must surely also be a disadvan-tage – I assume the system is not particularly cheap?
‘A complex device like this has its price. But the big advantage is that there is hardly any staff expenditure. The instruments are inserted, the device is started, and the instruments can be removed for further treatment after only 30 minutes. Over a long period of time, this represents a substantial time saving and clear benefits for staff in the CSSD.’

And the device makes manual labour unnecessary?
‘We have various examinations and test reports which show that pre-cleaning in the Trison 4000 is successfully carried out almost without needing any additional manual steps. The device was launched in 2017. More than 60 systems are currently in use in validated procedures across Europe, and user feedback is always positive. They especially value the intuitive handling, excel-lent cleaning results and the considerable relief in stressful working conditions.’

Could you give us a view into the future?
‘Robot-assisted surgery will con-tinue to increase. There will be more providers of robotic systems, along with completely new tech-nologies, new instruments and new procedures which will continue to alleviate and improve the treatment of patients. The Trison will be ready for the cleaning of new robotic instruments in future.
Bandelin always has an eye on new developments to ensure we can continue to meet this demand with innovative ultrasound equipment and to contribute to resource-saving cleaning of medical instruments.’
