Wasol’s new stereoscope(3-dimensional imaging) technology shows totally different approach beyond the established concept based on two-camera system. To provide a 3-dimensional image, Wasol’s technology applied only one camera which can move light axis. Wasol’s technical highlights as follows;


a. One camera system has got rid of the disaccording problems which are most crucial in existing two camera systems and have users free from dizziness during the long-hour use.


b. Wasol’s system can move and adjust light axes to close-up to object by macro.


c. All of the function including zooming, dollying, focusing etc. is identical to the normal 2 dimensional endoscope.

technique in which operations in the abdomen are performed through small incisions

(usually 0.5-1.5cm) as compared to larger incisions needed in traditional surgical

procedures. There are a number of advantages to the patient with laparoscopic surgery

versus an open procedure. The former one is of smaller incision, which reduces pain and

shortens recovery time. less pain, leading to less pain medication needed, and reduced

exposure of internal organs to possible external contaminants thereby reduced risk of

acquiring infections; therefore many operation requiring abdomen incision is replaced by

laparoscopic surgery.

that is, surgeons need to operate depending on instruments. Hence, the endoscope has

problems as follows.

companies specialized in medical imaging equipment have made efforts competedly to

develop 3D endoscope providing realistic view but failed in providing a satisfying results. For

example, Olympus made a prototype far behind performance expectancy and stopped further

developing any sequels. Many cases of development 3D endoscope have ended in failure

because the resulted prototypes have narrow visual angular field and make users to feel

dizziness. In addition, they didn't overcome the fundamental limits and problems of and

narrow angles of view and low magnification, and didn't secure the risk when operation.
