I can't put a blunt needle in it, can I prick it with a sharp needle?

If blunt needle penetration becomes difficult for various reasons, the use of sharp needles may be increased in some medical institutions, but the use of sharp needles in tunnels is not recommended. If a sharp needle is inserted into an established tunnel, the cutting action of the sharp needle tip may damage the tunnel wall, and may even cut off the established tunnel, resulting in the creation of a "false tunnel", resulting in future blunt needle punctures becomes more difficult.

If a sharp needle is used in the tunnel to "probe" intermittently for a long time, it will not only produce "false tunnel", but it may greatly increase the risk of tunnel infection.
