A guide for guiding a needle for insertion into a patient during a surgical procedure has a main guide body, a mounting arrangement for attaching the main guide body onto an ultrasound probe, and a needle cap that fits removably onto the needle guide. At least one channel is located between the main guide body and the needle cap. The needle cap is preferably made of a magnetic metal, and a magnet is preferably mounted in the main guide body. The needle cap is thus removably held on the main guide body by the force of the magnet. A multi-angle embodiment of the invention has a plurality of channels, each having a different, predetermined guide angle. The mounting arrangement preferably is in the form of a adjustable clamp, with a first and a second arm, which engage the housing of the ultrasound probe. The second arm preferably pivots in the main guide body depending on the position of an adjustment arrangement such as a thumbscrew.
