Disadvantages of blunt needles:

1. Skin injection cannot be performed;

2. The blunt needle forcibly breaks through to form a tear in the surrounding tissue, and the pain is strong, and it may break the surrounding blood vessels, and may also cause tear in the nerve ending fibers;

3. If it is a blunt needle with poor quality, the surrounding area of the needle hole is rough, and the blood vessel may be scratched during the puncture;

4. The inner diameter is much thicker than the sharp needle, and the bolus injection is smoother. Under the same operating pressure, the injection volume per unit time is several times that of the sharp needle. If the operation is improper, it is easy to inject too much in a certain part;

5. Most of the outer diameters are thicker than sharp needles. At the point of needle insertion, an additional fine sharp needle needs to be used to inject a small amount of anesthesia, and a thick sharp needle should be used to open the hole.

In general, both sharp needles and blunt needles have disadvantages and advantages, and there is not much advantage or disadvantage in essence. The key point is the ability of the user. However, in the medical plastic surgery industry, most medical staff will choose to combine use, as far as possible to minimize the risk.
