Precise on bone, gentle on critical structures

The ultrasonic-assisted bone instrument from Söring was developed specifically 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 fine approach, so that the surgeon can work closely to critical neurovascular spinal 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, removed material can be used further for fusion operations. Thereby artificial bone material or bone graft harvesting can be avoided.

"The bone instrument from Söring offers remarkable tissue selectivity and maximum safety for technically demanding operations on the spine without compromising ablation performance.”

Highlights

  • single use sonotrodes
  • various sonotrode geometries
  • simple, intuitive assembly
  • fully autoclavable instrument body
  • low instrument weight
  • clear view of the surgical field thanks to ergonomic design
  • integrated irrigation system

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, so that they can be reused.

  • 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
