You want your biopsy needle to be strong and safe. PET does not let much gas through and is very tough, so it is great for medical tools. When you use pet heat shrink for biopsy needle marking, you help make each biopsy safe and easy.

Application Steps

Needle Preparation

Start by preparing your biopsy needle. Clean the needle with alcohol wipes to remove any dirt or oil. Dry it with a lint-free cloth. This step helps the tubing stick well and keeps your biopsy safe. Always check the needle for any damage before you begin. If you see any bends or cracks, use a new needle. Good preparation gives you a strong base for marking.

Tip: Wear gloves to keep the needle sterile and protect your hands.

Tubing Preparation

Next, get your PET heat shrink tubing ready. Measure the length you need for the marking. Use sharp scissors or a blade to cut the tubing. Make sure the cut is straight and smooth. A clean cut helps the tubing shrink evenly.

You want the tubing to fit tightly on the needle. Choose a size that matches the needle’s diameter. If you use radiopaque marker bands, cut the tubing long enough to cover the band and hold it in place.

Dynamic Mechanical Analysis (DMA) also helps check how the tubing shrinks and how much stress it can handle. This test measures the tubing as it heats up, showing how well your preparation works. These tests make sure your tubing will shrink the same way every time.

Positioning Tubing

Slide the cut piece of PET heat shrink tubing onto the biopsy needle. Place it exactly where you want the mark to be. If you use a marker band, position the band first, then slide the tubing over it. Make sure the tubing covers the band fully. Hold the needle steady so the tubing does not move out of place.

Note: Take your time with this step. Good positioning gives you a clear and accurate mark for every biopsy.

Heat Application

Now you will shrink the tubing. Use a heat gun set to a low or medium setting. Hold the needle with tweezers or a clamp to keep your hands safe. Move the heat gun back and forth over the tubing. Keep the heat source about 2–3 inches away from the needle. Watch as the tubing shrinks tightly around the needle and any marker band.

Do not overheat the tubing. Too much heat can damage the needle or make the tubing brittle. Stop heating as soon as the tubing fits snugly. Let the needle cool before you touch it.

Inspection

After the tubing cools, check your work. Look at the mark to see if the tubing shrank evenly and covers the right spot. Gently tug on the tubing to make sure it stays in place. If you use a marker band, check that it does not move.

Manufacturers use strict quality checks to make sure every mark is clear and easy to see during a biopsy. They test the materials and watch the process closely. They also check the radiopacity of the mark, so you can see the needle clearly on scans. These steps help you get a safe and reliable mark every time.

Reminder: If you see bubbles, gaps, or loose tubing, remove it and start again. A good mark helps you work safely and accurately.
