Microprobes and Navigator

16 MHz DWL® Ultrasound-Probes are used to measure blood flow conditions in the microvascular region. Using the 16 MHz frequency it is not only possible to detect the blood flow in vessels near to the surface (non-invasive investigation), it is also possible invasively to place the probe directly on the wall of the examined vessel, for example in case of anastomosis. 16 MHz probes are available as disposable 2 or reusable probes.
Insonation depth of 16 MHz probes is approximately 0.5 mm to 8.0 mm.

 

16 MHz reusable probes standard or for endoscopic examination

Standard 16 MHz probes are available in diameters of 1, 2 and 3 mm with a cable length of 2.5 m. With its rigid cable the 16 MHz endoscopy probes are especially designed for endoscopic examination. The endoscopy probe has a diameter of 1.8 mm and a cable length of 2.5 m.

Cleaning and sterilization: 16 MHz probes are washable, but can not be autoclaved. For sterilization so called “cold” sterilization procedures like gas sterilization, formaldehyde sterilization and plasma sterilization are recommended.

16 MHz disposable probes 2

Disposable probes are intended for intraoperative applications e.g. aneurysm clipping. The sterile packed disposable probes have a diameter of 1.3 mm diameter and a cable length of 2.5 m.

 

Probe Navigator 2

The probe navigator for 16 MHz disposable probes is especially designed for save operation. The navigator consists of a handle and a mounted shaft, through which the 16 MHz probe is pulled.

The probe navigator is in different sets for different applications available:

Neurosurgery set
- Universal handle
- 2 bayonet shafts, short
- 2 bayonet shafts, long
- tray and sieve basket

Vascular surgery set
- Universal handle
- 2 straight shafts, short
- 2 straight shafts, long
- tray and sieve basket

Combination set
- Universal handle
- 2 bayonet shafts, short and long
- 2 straight shafts, short and long
- tray and sieve basket

 

Bayonet or straight shafts are separately available in sets of 3. A sterilization container is optional available.

Cleaning and Sterilization: Handle and shaft of the probe navigator are made of stainless steel and can be washed and autoclaved.

 

The probe navigator has been developed in close cooperation with the Clinic of Neurosurgery at the University of Mainz and Prof. Dr. med. Alf Giese.
