漏拆 - Meaning & usage? I tried several sources &amp; can't find a translation that seems correct.

An example sentence &amp; my attempt at translation:

嘴里漏拆了一根线怎么办？

mouth inside left behind remove a strip of thread what to do?

"There's a thread (of stitches?) left behind (not removed) in my mouth, what should I do?"

漏 means "missed" or "left behind"
拆 means "to dismantle" or "take down"

So 漏 is modifying the verb 拆 to make it mean "not dismantled or taken down", sort of.

Is my understanding correct? Can 漏 modify other verbs in this way?

Thanks in advance for any teaching!
First of all, "There's stitches left behind (not removed) in my mouth, what should I do?" is a good translation. 

Yes,漏 can modify other verbs. It means someone forgot to do something or some action has been missed.

Example:

A:"How you feel about the question 31 in the exam?"

B:"OMG, I didn't notice there was a question 31!"

A:"刚才考试第31题做的如何？"

B:"天啊！ 我漏做了!"
