The 5 1/2″ Dilator 0.3mm Diameter 13.5cm 9mm combines a 5 1/2-inch overall length with a 9mm tip size and slim configuration.
Its defined working profile is intended for gradual tissue dilation in neurosurgical applications.

Design & Function

The Dilator features a slim working configuration designed to provide a specialized orientation during tissue dilation. The 9mm tip design can assist in positioning the working end according to the requirements of the operative field.

The 9mm tip size provides a defined dilation profile, while the 5 1/2-inch overall length allows controlled manual positioning. Together, these dimensions provide a practical configuration for neurosurgical procedures requiring a slim dilator.

Surgical Applications

The 5 1/2″ Dilator 0.3mm Diameter 13.5cm 9mm may be used for neurosurgical and vascular applications involving gradual dilation of tissue or anatomical pathways. Specific use depends on the surgical procedure, technique, anatomical site, and preference of the clinical team.

Handling & Instrument Care

Inspect the dilator before use, paying particular attention to the working end and tip alignment. Ensure the instrument is properly aligned and free from visible damage or wear before use.

After use, clean and process the instrument according to the manufacturer's validated instructions and the healthcare facility's established instrument-processing protocols. Store the dilator appropriately to protect its working end and prevent unnecessary contact with other instruments.
