A laser angle guide assembly has a stand and a laser guide. The laser guide is rotatably attached to the stand and has a laser pointer, a transparent column, a guiding rod, an index stick and a protractor. The laser pointer has a head for emitting a laser. The transparent column is attached to the laser pointer to transfer the laser to an index line with an inclination. The guiding bar is attached to the laser pointer. The index stick is attached to the guiding bar and has an index section with an inclination parallel to the inclination of the index line. The protractor with graduations is rotatably attached to the index stick and corresponds to the index section. Accordingly, the laser pointer will generate an index line to provide a guide to the doctor to insert the needle into the patient body at a desired angle.
