Local insertion

Local insertion means putting something into a specific place instead of just dumping it anywhere. It's like when you want to put your toy into a box, you don't just throw it anywhere in the room, but you carefully put it into the box so it's in the right place.

In the medical world, local insertion is when a doctor or nurse puts medicine or a medical device, like a catheter or tube, directly into a specific part of your body. For example, if you need medicine for a sore throat, your doctor might use a special spray to insert the medicine directly into your throat.

This is helpful because it means the medicine or device goes exactly where it needs to be to do its job, and it can also help reduce side effects. It's like you're putting your toy in the right place so you can easily find it later, and it doesn't get lost or broken.
