<p>In or for a device for monitoring blood flow in an area during a surgical procedure in which an operating microscope allows a surgeon to observe the surgical procedure; and in which a laser light source illuminates the area, speckle laser light from the area being monitored is fed by a diversion means, to a processing means which converts the speckle laser light to an image representing blood flow, and display means to display the resultant image to the surgeon and/or his assistant; the improvement comprising so arranging said diversion means that said speckle light is divided into a first tranche feeding said processing means and at least a second tranche transmitting the image of the observed area to the surgeon through the microscope, thereby allowing the surgeon - or the surgeon and his assistant between them - a substantially unimpeded view of both the observed area under operation and the blood flow image created.</p> |
