Surgical tool guide

A surgical tool guide comprising:

• an anchor body extending between a proximal end and a distal end along an anchor axis, the anchor body having a piercing element at the proximal end adapted to pierce bone tissue and to anchor the anchor body thereto;
• an angle adjustor including an arcuate body arcuately extending between two opposed ends, visual angle markings displayed on a surface of the arcuate body, the angle markings indicative of measured angles therebetween, the angle adjustor mounted to the anchor body between the proximal end and the distal end;
• a guide including a tubular body cannulated along a longitudinal length thereof to define a guide passage extending therethrough along a guide axis, the guide mounted to the angle adjustor such that the guide axis intersects the anchor axis at a target surgical point and an angle is defined between the anchor axis and the guide axis, the guide passage adapted to receive and guide a surgical tool therethrough;
• and
• at least one of the anchor body and the guide displaceable relative to the other along the angle adjustor to vary at least one of the angle and a depth of the target surgical point, the depth defined between the piercing element and the target surgical point along the anchor axis.
