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 surgery, e. g. for decompression procedures. The non-rotating technology allows a very precise 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.

Macro instruments for liver surgery

Open and minimally invasive liver surgery

In liver resections, surgeons face the challenge of removing tumors while protecting vessels and bile ducts. The Macro instruments from Söring use both the cavitation and the mechanical effect of ultrasonic technology to reliably fragment 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.

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 impeeded^2,3.

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 that the healing process can proceed rapidly.

• Ulcers
• post-operative wounds
• trauma wounds
• infected wounds

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.
