Conditions
Interventions
Curved needle group (group C) :Group C: The puncture needle was pre-bent (approximately 10° curvature at 1 cm from the needle tip, with the outer arc surface facing the bevel opening of the needle tip
straight needle group (group S):In group S, straight needle was used for puncture without pre-bending, and the other procedures were the same as those in group C.
