Neurosurgery

Minimally invasive technologies are opening up new options in the field of neurosurgery, especially in the diagnosis and therapy of defects of the intracranial ventricles and the skull base. Endoscopes with different viewing angles allow a view of the anatomy of the brain, which is not possible with a microscope. The use of special endoscopes, with or without working channels, and dedicated micro instruments enable the surgeon to perform more advanced operative interventions.

A wide variety of interventions can be performed by an entirely endoscopic procedure, e.g., the removal of intraventricular cysts or tumors or the creation of the transnasal access to the pituitary gland and the skull base.
Another field of application is the so-called endoscopically assisted micro­neurosurgery which utilizes endoscopes to perform high-risk interventions in order to inspect areas that cannot be directly visualized and thus greatly enhances the safety of neurosurgical interventions.

KARL STORZ offers a wide range of instruments for intracranial interventions as well as for approaches to and procedures in the skull base area, complemented with a special pediatric portfolio. The scope of products is rounded off with a high-speed motor system with a multitude of drill, craniotomy and perforator handpieces.

Highlights

LOTTA® 30° for Intracranial Neurosurgery

Special Features:

  • Ventriculoscope with 30° direction of view
  • Sheath diameter 6.8 mm
  • The working channel (diameter 2.9 mm) and side channels (diameter 1.6 mm) allow bimanual dissection
  • A wide range of support features such as, for example, possibility of rotation in the sheath and instruments with length markings

Multimodal Visualization – NIR/ICG Vascular Fluorescence-assisted Endoscopy in Neurosurgery

NIR/ICG fluorescence imaging – an OPAL1® technology from KARL STORZ – enables the visualization of vascular structures in real time. The inflow of indocyanine green (ICG) can be made visible with light at wavelengths in the near infrared range.

The use of endoscopic NIR/ICG technology and the administration of indocyanine green (ICG) enables neurosurgeons to identify anatomic structures.

This allows the intraoperative perfusion assessment of tissue, the identification of neurovascular structures, the differentiation of tissue layers between tumors and adjacent structures as well as the visual evaluation of blood vessels and their perfusion.1

The 4 mm NIR/ICG neuroendoscopes are available with diverse directions of view (0°, 30° and 45°) and can be used with both near infrared imaging and standard white light.
