Microscopic surgery, Micro-surgery1101001-140
Surgical operation performed under a microscopeview.
One attractive technique today is surgery performed under a stereoscope.
While the technical term for this is microscopic surgery, in Japan it is
called micro-surgery. Microscopic surgery is practiced in otolaryngology,
ophthalmology, neurosurgery, vascular surgery, plastic surgery, and other
areas. Currently, surgery of the smallest scale is performed in suturing
arteries, veins, and nerves with a diameter of around 800 μm using needle
and thread with a diameter of around 20 μm. However, because surgeons must
manipulate the needle holder, forceps, and scalpel by hand and perform
the same actions as in ordinary surgery, these sizes of blood vessels and
nerves are considered to be the limit. Therefore micro-teleoperation and
other micromachine technology holds considerable promise for the future.
