I can't seem to figure out what "outside" has to do with "surgery".

Surely, one type of surgery is amputation (切断【せつだん】) which is about removing
(外【はず】す) a body part, but there are many other (much more common) type of
surgeries.

question
kanji etymology
Why does the word for "surgery" 外科 have the 外 kanji?
外科【げか】 stands in contrast to 内科【ないか】. While 内科【ないか】 has the straightforwardly
corresponding term "internal medicine" in English, I do not think the term
"external medicine" corresponding to 外科【げか】 has as much currency in modern
English-language medical materials, where instead this is rendered as
"surgery". (Separately, I do note that the term "external medicine" seems to
have some use in English-language Chinese medical contexts.)

That said, broadly speaking, "internal medicine" is concerned with treating
the body from the inside, via medicines, behaviors, diet, etc. Meanwhile,
"surgery" is concerned with treating the body from the outside, by opening
things up or otherwise entering the body from the outside (such as via
endoscopic techniques). This rough categorization of medical approaches is
expressed in Japanese as 内科【ないか】 and 外科【げか】.
