5 Must-Have Features in a ultrasonic surgical system

Ultrasonic surgery instruments

How it works Ultrasonic instruments vibrate typically at 55 kHz, creating a wave of mechanical energy. This ultrasonic energy is transferred from a blade to tissue molecules, which begin to vibrate in response. The vibration improves the cutting and leads to a better coagulation of the tissue, thereby reducing bleeding. The reaction to the vibrations depends on the density of the objective (tissue, bone etc.) and the frequency of oscillation. As an example, bone reacts most to frequencies in the low ultrasonic range (20-25 kHz).

Which piezo elements can be used for ultrasonic surgical instruments? 
Usually, monolayer piezo components are used in ultrasonic surgery tools. Transducers require medium power elements, for example small rings made of our hard doped material NCE41, which is designed for medium to high power devices. Noliac can provide piezoelectric components according to your specifications.

In some cases, these monolayer components can be replaced by multilayer components, which will allow a drastic reduction of the operating voltage while keeping the same performance and as such reduce the electrical safety requirement when operating in the human body. Multilayer components can be provided by Noliac according to your specifications. 

Custom designed transducer
We have a long history of designing and developing customized transducers for ultrasonic surgery devices. Therefore, we know the typical challenges when designing this type of transducer. For instance, the importance of a proper resonance frequency for requested amplitude, the tuning of performance versus minimum losses of the device, to have minimal impedance in resonance, or how to avoid parasitic resonances in working range of frequencies.

Dental ultrasonic surgical systems

 

Dental ultrasonic surgical systems use high-frequency piezoelectrics to cut bone and prepare oral surgical sites. Because these systems reduce heat they are able to perform osseous surgical procedures with less trauma to the patient. An ultrasonic surgical system will not harm soft tissue, making surgical procedures safer for patients. When selecting an ultrasonic surgical system you should look into the tip options available as well as the setting options. As with any equipment investment be sure to choose a system with a warranty, training, and support.

Introduction to Ultrasonic Surgical Devices

Introduction to Ultrasonic Surgical Devices

 

Ultrasonic surgical devices represent a remarkable leap forward in the field of modern surgery. These innovative instruments have revolutionized the way surgical procedures are performed, offering numerous advantages over traditional surgical tools. In this comprehensive guide, we will delve into what ultrasonic surgical devices are, how they work, and the significant advantages they bring to contemporary medical practices.

 

What Are Ultrasonic Surgical Devices?

  Ultrasonic surgical devices , often referred to as ultrasonic scalpels or harmonic scalpels, are advanced surgical tools designed to perform precise cutting, coagulation, and dissection in various surgical procedures. They utilize ultrasonic vibrations to achieve exceptional levels of precision and control during surgery.

What are the two types of ultrasonic devices?

 

There are primarily two types of ultrasonic devices used in various applications, including medical and industrial fields:

 

Ultrasonic Cleaning Devices:

 

Purpose: Ultrasonic cleaning devices use high-frequency sound waves, typically in the range of 20 to 400 kHz, to clean and remove contaminants from objects immersed in a liquid solution.
Operation: These devices work by creating cavitation bubbles in the cleaning solution. The rapid formation and collapse of these bubbles produce intense microscopic shockwaves that dislodge dirt, grease, and other contaminants from the surfaces of the objects being cleaned.

 

Ultrasonic Surgical Devices (Harmonic Scalpels):

 

Purpose: Ultrasonic surgical devices, often referred to as harmonic scalpels, are specialized surgical instruments used by healthcare professionals in various surgical procedures. They use high-frequency ultrasonic vibrations to perform precise cutting, coagulation, and tissue dissection.

 

While both types of ultrasonic devices use ultrasonic vibrations, they serve different purposes and operate under distinct principles. Ultrasonic cleaning devices are designed for cleaning and removing contaminants from objects, while ultrasonic surgical devices are tailored for precision cutting and coagulation in medical procedures.

 

How Do Ultrasonic Surgical Devices Work?

 

Ultrasonic surgical devices operate on a fundamental principle of converting electrical energy into mechanical vibrations. Here's a simplified breakdown of their operation:

 

Generator: The system starts with an ultrasonic generator, which generates high-frequency electrical energy typically in the range of 20,000 to 60,000 Hertz (Hz).

 

Transducer: This electrical energy is then transmitted to a handpiece containing a transducer. The transducer converts the electrical energy into mechanical vibrations at the same high frequency.

 

Tooltip: The mechanical vibrations are transferred to the surgical tip or blade, causing it to oscillate rapidly. This oscillation generates friction and heat at the tissue interface.

 

Tissue Interaction: When the vibrating tip comes into contact with the tissue, it efficiently cuts or coagulates the tissue due to the heat generated, while minimizing collateral damage to surrounding healthy tissue.

 

 

The purpose of this write-up is to provide clinical staff with details surrounding ultrasonic cleaning. In Sterile Processing, we are tasked with multiple IFU&#;s, parameters, and regulatory checklists. We want to provide you with the basics of what you need to know when it comes to ultrasonic cleaning.

How does ultrasonic cleaning work?

Ultrasonic cleaning removes particulates by cavitation (bubbles) and implosion. Cleaners are used in conjunction with detergents and enzymatic cleaners. Waves of acoustic energy are transmitted in aqueous solutions and disrupt the bonds that hold particulate matter to surfaces.

Most instrument manufacturers recommend ultrasonic cleaning as the most effective way to clean instruments, particularly those with hinges, locks, and other moving parts. Ultrasonic cleaners are considered a Class 1 medical device by FDA. They do not disinfect or sterilize instruments; however, when used in conjunction with manual cleaning, sonic cleaning can enhance the cleaning process and increase the effectiveness of disinfection and sterilization.

 

The parameters include; cavitation, flow sonic irrigation, and detergents.

The ultrasonic cleaning process allows for scrubbing action to reach small crevices, irregular surfaces, and internal passages, without damaging the intricate device. Ultrasonic washers are designed to dislodge challenging soils from the surface and lumens on instruments and provide consistent cleaning results throughout the washer chamber.

 

Per AAMI ST79/ 7.6.4.3.3 Selection of Mechanical and Disinfection Equipment: there are several types of Ultrasonic cleaners:

1. Ultrasonic cleaning equipment

2. Ultrasonic irrigators

3. Ultrasonic irrigator washers

4. Ultrasonic irrigator washer-disinfector

When to test your sonic:

Per AAMI ST79/ 7.6.4.4.1 General Consideration

B) Perform cavitation testing daily whenever the equipment is in use. Per AAMI ST79/ Annex D3 Cleaning Verification Tests for Users: Verification Tests for Ultrasonic Cleaners

Top considerations for your ultrasonic

1. Test for cavitation in an ultrasonic bath

• Indication can be the physical measurement of visual assessment
• Test for Soil Removal (external) in Ultrasonic Bath
• Indication is visual assessment or absence of marker on coupon placed in the ultrasonic bath
• Test for soil removal (internal within lumens) in Ultrasonic Bath
• Indication is visual assessment or absence of marker on a coupon placed in the ultrasonic bath

2. Water change after each use

AAMI ST79/

7.6.4.4 Ultrasonic Cleaning Equipment

7.6.4.4.1 General considerations

Ultrasonic cleaning should be:

d) performed with fresh cleaning solutions; solutions should be changed after each use (a &#;use&#; should be defined in the health care facility&#;s policies and procedures); and

e) followed by thorough clean water rinsing or detergent washing to remove ultrasonic cleaning equipment bath residues and contaminants.

3. Critical water is recommended

AAMI Standards TIR34

5.2.1.3 Rinsing

Tap water is often adequate for rinsing and removing soil loosened by the cleaning process and for rinsing and removing detergent residues, provided that it meets the requirements for Utility Water. However, if the quality of the tap water could cause corrosion, tarnishing, or salt deposits, it might be necessary to use various water treatment processes (e.g., softening, deionizing) to ensure that devices are not damaged and the ensuing disinfection or sterilization process will be effective. For devices that will contact the bloodstream of other sterile areas of the body, the final stage in rinsing requires water that does not have excessive levels of organics (e.g., endotoxins or other microbial constituents); therefore, critical water is recommended.

 

Per AAMI ST79/

7.6 Cleaning

7.6.1 General Considerations

c) Devices should be thoroughly rinsed. If a basin is used, the rinse water should be changed after each use. The final rinse (mechanical or manual) should be with purified water (e.g., distilled or RO water). See TIR34 for recommendations on the use of critical water.

4. Not all ultrasonics reprocess the same

There are some ultrasonics that are validated for reprocessing da Vinci Endowrists. We validated the Skytron Flex for mixed loads in the same cycle. That means you can reprocess your da Vinci, Orthopedic, cannulated, and non-cannulated in the same 35-minute cycle which includes thermal disinfection and critical water final rinse.

Meet our Skytron Flex washer-disinfector

• Clean All Ultrasonic Approved Instruments in One Cycle: Versatile design with the ability to irrigate cannulated instruments such as the da Vinci products and non-cannulated instruments in the same cycle.
• The Flex ultrasonic instrument cleaner can wash and disinfect up to 125 pounds of instrumentation using your current ultrasonic trays. Includes up to 6 trays per cycle
• Achieve optimal disinfection standards: the Flex Ultrasonic surgical cleaner only irrigates with fresh water and detergent and drains contaminated water after each cycle.

What do our customers say?

&#;The Skytron Flex has been a lifesaver for our department. The efficiency of throughput and being able to sonicate and wash along with a thermal rinse cycle in less than 40 minutes has been a game-changer for us. Being able to process up to 24 robotic arms in one cycle as well as using our existing trays to place orthopedic items into the unit reduces overall throughput time in decontamination.&#;
