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 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
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.
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.
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.
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.
Show me a facility that didn't do its due diligence before buying an instrument- washer, and I'll show you a bad case of buyer's remorse. As a sterile processing consultant, I see a lot of expensive eyesores. If you're in the market for a new washer, or expect to be soon, here's some advice to help make sure you don't end up regretting your decision.
Talk to other users before you buy
There are many critical issues to consider when you're looking at washers. How easy is it to use? Is it complicated for your staff to select the cycle, and to read and interpret the cycle? Do you have to make any major changes with the baskets you use? My advice: Don't buy anything until they've talked to a facility that has had the same machine for at least a year, and ask whether they'd purchase it again.
Some facilities overbuy, wasting money on fancy accessories they never use. For example, many ultrasonic cleaners come with special inserts and tubing that can be used to clean lumens. But at facility after facility, I see those attachments sitting in a corner unused. Why? They're too much trouble to hook up, people say, so we don't use them. Which means they likely wasted $4,000 or $5,000.
With washers, there are a lot of different options available, depending on your needs, and most are very efficient. Machines are getting more versatile and more user-friendly, and are increasingly equipped with cycles that are more attuned to the demands of outpatient facilities. One goes through the entire cycle and does a great job in 40 minutes. Manufacturers realize that the goal has to be to increase throughput without increasing footprint, and they've been able to shorten rinse and dry cycles to improve efficiency.
Remember, if a washer is going to be used for multiple purposes, you have to make sure people are using the correct cycles and the correct detergent. The wrong detergent can destroy instruments.
Another step in the right direction is the introduction of multi-level sonic cleaners. That's huge, especially for orthopedic facilities with limited space, where at any given time you might have 20 trays that need to be sonic-ed before they go into the washer. Too often, people are inclined to simply skip that crucial step. Now you can handle several trays simultaneously in one machine, provided they all require the same amount of sonication time.
A washer can't do everything. The ideal cleaning process typically starts with an enzyme soak, is followed by ultrasonic cleaning, and then by mechanical washing. Virtually every instrument manufacturer's instructions for use (IFU) recommend including ultrasonic cleaning as part of the reprocessing process. If you don't have an ultrasonic cleaner and bypass that step by placing instruments directly in the washer, you're not complying with the IFUs. You're in effect saying you know more than the manufacturer, and you think you can get the device clean by doing it your way instead.
Mechanical washers and ultrasonic cleaners have different processes and different functions. Ultrasonic cleaners agitate water and create bubbles that implode and create pockets of suction around instruments. They're good at removing debris out of all the nooks, crannies and serrations, but they don't disinfect. Washers, on the other hand, aren't nearly as effective at dislodging debris from hard-to-reach areas, but they do usually raise the temperature at the end of the cycle to a level that reduces microbial count.
Some facilities may be able to get by with just an ultrasonic cleaner (as long as that's the instrument manufacturer's recommended protocol and the people doing the prepping and packaging wear powder-free gloves), but most need multiple pieces of equipment to comply with the manufacturer's IFUs.
And you'll need more than one. You should never have just one of any type of equipment, because when it goes down, which it inevitably will, you'll be facing a major problem. This may be one of the reasons that tunnel washers — the car-wash types that let you put instruments in one end and have them come out the other end having gone through all the essential cycles — seem to be falling out of favor with both manufacturers and users. In addition to providing less control — for example, you can't change the length of time instruments spend in the sonic cycle, which is an important consideration in orthopedics — they take up a lot of space and are extremely expensive. For the price of one tunnel washer, you can get several mechanical washers.
Test your cleaners every day
A lot of surgical centers that were set up to do small procedures and have since gone way beyond that still have small processing rooms and a small tabletop ultrasonic cleaner that's not powerful enough to do the job. So the staff doesn't use it.
We live in a litigious world. Surgeons have the right, legally speaking, to assume that everything brought into the OR is safe to use. If an instrument turns out to be unsafe, the person running the facility is the one who's liable.
