Surgical Dopplers and Probes


20MHz and 8MHz transceivers and probes provide intraoperative audio blood flow detection at different depths for your surgical needs.

 


Mizuho offers a portable, easy-to-use, and accurate modality for evaluating blood flow intraoperatively. Two systems operating at two different frequencies, 8MHz and 20MHz, provide audio blood flow detection at different depths of penetration. Each system comes with a set of transceivers and sterile disposable probes designed for specific surgical procedures.

 


Mizuho 8 MHz Surgical Doppler System

2cm depth penetration depending on the density of surrounding tissue and bone.

Clinical Benefit
Minimize the risk of internal carotid artery injury during transsphenoidal surgery
Indications:

 

  • Locates carotid artery in transsphenoidal procedures
  • Allows technical verification of anastomoses and endareterectomies
  • Supports assessment of flap viability
  • Evaluates AV fistulas and EC-IC Bypass
  • Verifies graft and shunt patency

Mizuho 20 MHz Surgical Doppler System

1cm depth penetration depending on the density of surrounding tissue and bone

Clinical Benefit
Quickly assess aneurysm clip placement and confirm aneurysm occlusion
Indications:

 

  • Locates feeder artery in AVM
  • Locates vessels noted on angiogram
  • Determines completeness of aneurysm clipping
  • Determines patency of parent vessel post aneurysm clipping
  • Validates patency of microvascular anastomoses
  • Confirms patency of major venous sinuses

This highly sensitive, low-profile Doppler probe allows real-time carotid localization for microscopic and endoscopic transsphenoidal procedures.

 

  • Packaged four to a box
  • Sterile disposable
  • 133.35 working length, 267 mm overall
  • Bayoneted, 2mm tip
  • Last 10mm of tip bent at 10 degrees
20 MHz Surgical Probe
pic_doppler_6

The Mizuho 20 MHz Surgical Doppler probe is easy to use. The probe tip is 2mm in diameter, making it extremely precise, while not taking up the whole field of view.

 

  • Packaged four to a box
  • Sterile, disposable
  • 110mm working length, 275mm overall
  • Bayoneted, 2mm tip
20 MHz Surgical Micro Probe
pic_doppler_7

Although similar to the 20 MHz Surgical Doppler Probe, the bayonet handle probe features a low profile tip which has a diameter of 0.8mm. This allows for optimal visibility around the surgical site.

 

  • Packaged four to a box
  • Sterile, disposable
  • 140 working length, 280mm overall
  • Bayoneted, 0.8mm tip
