Tisdale told BBC Devon: "I'm not looking for any players, I'm happy with the players that I've got.
"If we lose four or five players in the next two or three days to injury then maybe, but I wasn't even aware about it [the window closing] on Thursday."
Tisdale added: "I'm so focused on the players that we have.
"These players are going to get us to where we can get to this year, what that will be I don't know, but I'm very much behind them and we'll see what happens."
Tisdale made the comments shortly after his players fought back from 3-0 down to draw level with Oldham in League One on Tuesday, leaving them 11th in League One.
He said: "It was a really good moment for us and hopefully we can bottle a bit of that feeling now and take it into the next few weeks."
Having gone out of the FA Cup to Bury in the first round, Exeter have a rare Saturday off this weekend, something Tisdale is aiming to make the most of.
He said: "We'd rather be in the FA Cup, but we're not, so I think we'll harness the fact that we've now got seven days to rest."
