Innovative ultrasonic surgery by Söring
Bringing State-of-the-Art Technology into
the Scandinavian Veterinarian Market
It is our pleasure to introduce the expertise and product portfolio of Söring to the Scandinavian Veterinary medicine market.
Söring GmbH has been manufacturing high-end products for ultrasonic surgery for over 35 years for the human medicine segment and is widely used in hospitals all over Scandinavia.
Since 2019 Söring GmbH has taken a step into the veterinarian field, enabling Equine veterinarians to use ultrasonic technology to improve wound debridement and orthopedic surgery.
The Söring technology has also provided Small Animal veterinarians with new tools for soft tissue surgery using the ultrasonic organ portfolio in cancer and organ indications, on top of the wound debridement, bone, and spine surgery – using the full portfolio of Söring.

Ultrasonic Surgery – product overview
Söring Ultrasonic Instruments
Ultrasonic-Assisted Wound Debridement (UAW)
Easy handling for veterinarians and veterinarian nurses
With their different sonotrode shapes, the UAW instruments from Söring are specially adapted to the needs of Ultrasonic-Assisted Wound Debridement. Veterinary doctors and specialized veterinary nursing staff can use them in or outside disinfectable treatment rooms, making them a versatile option for the Equine clinic environment. Due to their reprocessability and longevity, UAW instruments meet the requirements for a resource-saving treatment option.
The working frequency of 25 kHz makes UAW instruments attractive in various indications. In addition, their ergonomic design enables precise and fatigue-free work throughout the treatment period.
Ultrasonic-Assisted Bone Instrument
Precise on bone, gentle on critical structures
The ultrasonic-assisted bone instrument from Söring was explicitly developed for the resection of bone and offers numerous advantages in spinal and bone surgery, e. g. for decompression procedures. The non-rotating technology allows an exact, delicate, and cooled approach so the surgeon can work closely with critical spinal neurovascular structures such as the dura mater, blood vessels in splint bone, or bone flap surgery. Additional pressure is avoided, which is essential when working in tight spaces. Due to the longitudinal movement of the sonotrode tip, there is also no risk of “grabbing.”
Another great advantage compared to other instruments is that bone can be removed in individual pieces, as it is not ground. Thus, the removed material can be used further for fusion operations. Thereby artificial bone material or bone graft harvesting can be avoided.
HEPACCS instruments for soft tissue tumor surgery
Open and minimally invasive liver and soft tissue tumor surgery
In liver resections and soft tissue tumor surgery, surgeons face the challenge of removing tumors while protecting vessels and bile ducts. The HEPACCS instruments from Söring use both the cavitation and the mechanical effect of ultrasonic technology to reliably fragment, for example, liver parenchyma at 25 kHz. Solid tissue structures of vessels and bile ducts remain largely unscathed. Depending on the tumor’s size, number, and location, resection can be performed in open or laparoscopic surgery.
Söring ultrasonic generators
Simple, intuitive, and for a wide range of medical applications
After a short set-up, the user can start immediately. Thanks to the intuitive user interface, the working parameters can be easily adjusted at any time during the procedure so that the user can react quickly to changed circumstances.
Söring’s ultrasonic generators are used in medical applications ranging from liver and soft tissue tumor surgery, neurosurgery, and spine and bone surgery to Ultrasonic-Assisted Wound Debridement (UAW).
SONOCA 300-FL
Specialist for wound debridement, bone surgery, and tumor surgery
Whether for liver, tumor, neuro, spinal surgery, wound debridement, or cutting and coagulation – the SONOCA 300-FL is the efficient specialist for all of Söring’s ultrasonic applications.

the following ultrasonic instruments:
Ultrasonic Assisted Wound Debridement (UAW)
UAW instruments: versatility for a range of wounds
For optimal treatment results, Söring offers three UAW instruments with unique sonotrode tips optimized for different wounds.
How does it work?
Effective and gentle wound cleansing
Debridement plays an essential role in the treatment of complex wounds. As part of wound management, it prepares the wound bed to promote rapid and complete healing.

A key facility of the Ultrasonic technology is the ability to debride “blind” on hard-to-reach areas using the short or long version of the double ball instrument.
Ultrasonic-Assisted Wound Debridement (UAW) is a very effective and gentle method for cleansing chronic and acute wounds with a worldwide unique level of evidence. Even hard-to-reach areas can be debrided without an extensive surgical scenario. Wound treatment can be carried out on an outpatient basis and with local anesthesia by a veterinarian or specialized veterinary nursing staff.
In contrast to traditional sharp debridement procedures, the UAW disrupts adhering biofilms 1 and enables the effective removal of devitalized tissue close to healthy tissue. This results in a clean, viable wound bed 2,3,4,5 and a more rapid granulation 5. Antimicrobial therapies 6 and the body’s defense reactions can work better, and the formation of new bacterial biofilms is impeeded2,3.

Cavitation Effect
Ultrasonic technology in wound debridement

The UAW instrument generates cavitation bubbles that implode due to pressure changes and generate strong sonic shock waves, so-called microjets, which remove revitalized tissue and disrupt the biofilm.
Cavitation Effect
Söring’s Ultrasonic-Assisted Wound Debridement uses the cavitation effect. The ultrasonic vibrations of the UAW instrument generate cavitation bubbles in the irrigation solution. Those bubbles implode due to pressure changes and generate strong sonic shock waves, so-called microjets.
Healthy Tissue is hardly affected.
Devitalized tissue and foreign bodies are removed from the wound bed, and biofilms are disrupted. Healthy tissue is hardly affected due to its higher elastin content, so the healing process can proceed rapidly.
Indications
Acute and chronic wounds
- Ulcers
- Hypergranulation tissue
- post-operative wounds
- trauma wounds
- infected wounds
Wound debridement – what is needed?

Ultrasonic-assisted bone instrument
Precise on bone, gentle on critical structures
The ultrasonic-assisted bone instrument from Söring was explicitly developed for the resection of bone and offers numerous advantages in spinal surgery, e. g. for decompression procedures. The non-rotating technology allows an exact and delicate approach so that the surgeon can work closely with critical spinal neurovascular structures such as the dura mater. Additional pressure is avoided, which is extremely important when working in already tight spaces. Due to the longitudinal movement of the sonotrode tip, there is also no risk of “grabbing.”
Another great advantage compared to other instruments is that bone can be removed in individual pieces, as it is not ground. Thus, the removed material can be used further for fusion operations. Thereby artificial bone material or bone graft harvesting can be avoided.
Different sonotrodes for an individual procedure
The surgeon can choose between two sonotrode shapes and lengths and optimize the instrument regarding indication, procedure, and access route.

Knife sonotrode
The blade-shaped sonotrode cuts out vital bone pieces precisely and with a straight-cut surface.
- Longitudinal ultrasonic oscillations (35,000 times per second)

Rasp sonotrode
The rasp-shaped sonotrode is used for precise bone ablation.
- Longitudinal ultrasonic oscillations (35,000 times per second) in combination with torsional motion
What is needed?

- single use sonotrode (rasp or knife)
- reusable bone instrument
- ultrasonic generator SONOCA 185 or SONOCA 300 and accessories

Principle of ultrasonic technology in spinal surgery
The ultrasonic oscillations of the sonotrode tip and the manual movement of the bone instrument allow precise and controlled cutting through bone and targeted bone removal. Elastic structures are significantly more resistant to ultrasonic oscillations. Since they can adapt to the oscillations, they remain intact in the event of contact with the sonotrode tip.
