Abstract
Needle guide systems for a sonography device are disclosed. The needle guide systems include both fixed and adjustable needle guides. In one embodiment, the needle guide includes a needle guide body that is rotatably mounted to a probe of a sonography device. A plurality of needle channels is disposed on a surface of the needle guide body. Each needle channel can be selectively rotated into position to guide a needle into a body of a patient at a predetermined needle insertion angle. If another needle insertion angle is desired, the needle guide is rotated to place a new needle channel defining the desired needle insertion angle into position. In another embodiment, a needle guide is disclosed and includes an extended guide feature, such as a guide cone, to assist in inserting a needle into the needle channel.
