Surgical application of zoom stereo microscope Microstereopsis announces what it says is the world’s first PC-based digital 3D(imaging system) viewing and video recording system for use on zoom stereo surgical microscope. Retro-Opsis DV offers a quick upgrade to real time 3D for existing surgical operating microscopes. Retro-Opsis DV is also useable on any parallel optic zoom stereo microscope with suitable adapters and beamsplitters. The most up-to-date progressive scan digital cameras are included as well as software, image erecting optical couplers, a high-end PC with a full terabyte Raid system and plug and play operation anywhere on the globe. The system offers sync doubling 3D and high performance active eyewear viewing by multiple viewers. System includes firmness routine and integrated DVD burning functions. filled audio and visualisation on 21″ CRT monitor. Retro-View systems are obtainable for interactive DVD-ROM viewing or projection in 3D.

Zoom stereo microscope is aiding a number of global stent manufacturers to provide highly sophisticated products to make angioplasty heart surgery a safer and less difficult procedure. The ground-breaking and ergonomic inspection system is used to ensure that the exacting precision requirements for these devices are met, limiting the serious medical consequences and liability issues that arise from heart surgery. Angioplasty heart surgery involves using an inflated balloon to dilate and unblock a blood vessel from the inside - a procedure that first took place in 1977 in San Francisco. in view of the fact that , the technique has evolved dramatically, and stents are sometimes now used to provide a ‘mechanical scaffolding’ inside the artery to prevent its fall down. Stents are tubular alloy reinforcements that are cemented to the ballon and connected to a wire for control and positioning. They are used to maintain the patency of coronary vessels following angioplasty surgery, and to a great extent improve the chances of success both immediately and on a long-term basis. Unbelievably, following this surgery patients are normally discharged the next day and can start again routine activities a few days later. Stent manufacture has seen a large number of innovations from a wide range of different international suppliers. On the other hand, when dealing with a device with a typical diameter of just 2mm and a length of just 15mm, precision and class are the common and all-important factors - especially given the medical nature of their use. It is for the reason that of these factors that manual inspection of every single manufactured device is necessary.

The barrel of the stent must be inspected for surface inclusions and the edges inspected for burrs and smoothness at the same time as, on assembly, the cement from the balloon must not wick onto the barrel. Conventional inspection methods have utilized a microscope with ring illumination. However, the surface glare produced by this method has led to a resulting inability to detect manufacturing faults and reduced throughput due to the ergonomic constraints of sustained eyepiece microscope usage. Vision Engineering has been able to supply the perfect solution to these problems with its eyepiece less zoom stereo microscope. The eyepiece less zoom stereo microscope, user-friendly viewer assembly permits a much greater degree of body position choice for the operator and delivers a pin sharp stereo image. By means of the operator benefiting from the resultant eye relief and the optimal positioning of user controls for ease-of-use and long-term comfort, accuracy and productivity are both greatly improved. The operator is able to resourcefully inspect the surface of stents in the great detail required for this claim, clearly detecting faults such as wicking. As a result of these only one of its kind benefits, the eyepiece less inspection system has been adopted by some of the most innovative stent manufacturers in the world. These include: Inflow (Germany); Cordis (USA); Boston Scientific (USA); CR Bard (USA); Guidant Technology (Ireland); Nemed Tippi (Turkey); and AVE Metronics (Ireland). In turn, with these manufacturers’ devices becoming evermore precise, patients needing heart surgery are far more likely to make a complete and fast recovery.
