Söring ultrasonic/ high frequency instruments

Generators for dissection:
The Sonoca ultrasonic generators provide an alternating current which is converted into mechanical vibrations in the converter of an ultrasonic instrument.

The surgeon has a wide range of ultrasound handpieces available for neurosurgery.

For coagulation:
The high-frequency voltage produced by the CPC generator ionises helium gas introduced by means of the handpiece and thereby generates a "cold" plasma jet at the end of the CPC probe.  

The high-frequency current generated is routed through a connection cable to the CPC handpiece with corresponding CPC probe.

           
Indications

Cranial indications
In brain surgery, Söring ultrasonic instruments are mainly used for the removal of soft and hard tumours. The tumour mass is reduced by placing the Sonotrode into the tumour mass and then aspirating the cell fragments by means of the aspiration fluid.

Dissection:
Ultrasonic dissectors for the fine dissection of tumour tissue.

Coagulation:

• Surface coagulation without formation of necrosis of the resected tumour cavity.
  Söring irrigation forceps
  CPC handpieces
• Delicate spot coagulation without adhesion of tissue to the forceps tip and only minimal thermal damage to the surrounding tissue
  Söring NON-STICK bipolar irrigation forceps

Spinal indication
In spinal surgery, Söring ultrasonic bone scalpels are used for the removal of bone fragments, particularly in spinal stenosis and for the removal/ partial removal of vertebral bodies/ vertebral arches and sequestered intervertebral disc fragments.

Use of ultrasonic bone dissectors

Indications in the area of the cervical spine:

• Endoscopic anterior cervical discectomy with canal decompression
• Endoscopic posterior cervical laminoforaminotomy with discectomy
• Endoscopic posterior cervical laminectomy with opposite canal decompression

Indications in the area of the lumbar spine:

• Endoscopic lumbar discectomy
• Open and microscopic access to the spinal column
