Totally endoscopic coronary artery bypass surgery
Encyclopedia
Totally Endoscopic Coronary Artery Bypass Surgery (TECAB) is an entirely endoscopic
robotic surgery
used to treat coronary heart disease
, developed in the very late 1990s. It is an advanced form of Minimally Invasive Coronary Artery Bypass Surgery
, which allows bypass surgery to be conducted off-pump without opening the ribcage. The technique involves three or four small holes in the chest cavity through which two robotic arms, and one camera are inserted.
system. The system consists of a robotic "slave" system at the bedside. The robot relays its information to an external surgical control unit, where a cardiac surgeon
has a three-dimensional view of the chest cavity, and twin-controllers for the robotic arms. The procedure frequently involves grafting

Endoscopy
Endoscopy means looking inside and typically refers to looking inside the body for medical reasons using an endoscope , an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ...

TECAB surgery uses the da Vinci tele-robotic Stereoscopic 3-D ImagingStereoscopy
Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth...

Medical grafting
Grafting refers to a surgical procedure to move tissue from one site to another on the body, or from another person, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. A similar technique where tissue is transferred with the blood supply intact...
