Various shaft guide embodiments are disclosed and may comprise a shaft guide body that comprises a proximal end that may have an oval shape aligned on a proximal long axis and a distal end that may have a distal oval shape aligned on a distal long axis that is transverse to the proximal long axis. The shaft guide body may further comprise a first passage that defines a first passage proximal opening oriented in a first orientation and a second passage that defines a second passage distal opening that is oriented in a second orientation that differs from the first orientation.
