The system includes an outer housing forming an internal lumen along an axis with a distal foot with a surface configured to be secured to a patient’s skin. A carriage sleeve is slidably positioned within the internal lumen. A distance gauge on the carriage sleeve is visible through a window for providing a user an indication of a distance of movement of the carriage sleeve. An actuator is coupled to the outer housing, wherein the actuator is actuated to slidably move the carriage sleeve through the internal lumen. ## Claims ### Claim 1 An anchor system for securing a delivery tool to skin, comprising: an outer housing forming an internal lumen along an axis, the outer housing having a distal foot with a surface configured to be secured to a patient’s skin; a carriage sleeve slidably positioned within the internal lumen, wherein the carriages sleeve is configured to be attached to the delivery tool; a window on the outer housing, wherein a distance gauge on the carriage sleeve is visible through the window for providing a user an indication of a distance of movement of the carriage sleeve; and an actuator coupled to the outer housing, wherein the actuator is actuated to slidably move the carriage sleeve through the internal lumen. ### Claim 2 (depends on 1) The anchor system of claim 1, wherein the surface of the distal foot is flat. ### Claim 3 (depends on 1) The anchor system of claim 1, wherein the surface of the distal foot is contoured. ### Claim 4 (depends on 1) The anchor system of claim 1, wherein the distal foot is a flared body. ### Claim 5 (depends on 1) The anchor system of claim 1, wherein the delivery tool is a spinal needle. ### Claim 6 (depends on 1) The anchor system of claim 1, further comprising an adhesive on the surface of the distal foot, the adhesive configured to adhere the distal foot to skin. ### Claim 7 (depends on 1) The anchor system of claim 1, wherein the actuator is a rotatable thimble. ### Claim 8 (depends on 1) The anchor system of claim 1, wherein the anchor system has a plurality of distal feet each configured to be secured to a patient’s skin. ### Claim 9 (depends on 1) The anchor system of claim 1, wherein each distal foot is coupled to at least one actuating joint configured to adjust a trajectory angle of the delivery device relative to an entry site and a target area. ### Claim 10 (depends on 1) The anchor system of claim 1, wherein the distal foot is detachable. ### Claim 11 (depends on 1) The anchor system of claim 1, wherein the outer housing is configured to lock a position of the delivery tool in place at a target location on the skin or table. ### Claim 12 A method of securing a delivery tool to a patient, comprising: attaching an external anchor system to a skin surface of a patient; inserting a delivery tool into a carriage sleeve of the external anchor system and securing the delivery tool to the carriage sleeve; sliding the delivery tool along an axis defined by the external anchor so that the delivery tool penetrates the skin surface of the patient; and actuating an actuator of the external anchor so that the carriage sleeve and the delivery tool collectively move along the axis. ### Claim 13 (depends on 12) The method of claim 12, wherein the delivery tool is inserted into the carriage sleeve while the carriage sleeve is coupled to the external anchor. ### Claim 14 (depends on 12) The method of claim 12, wherein the delivery tool is inserted into the carriage sleeve prior to coupling the carriage sleeve to the external anchor. ### Claim 15 (depends on 12) The method of claim 12, wherein the actuator is a rotatable thimble and wherein actuating the actuator comprises rotating the thimble so that the carriage sleeve and the delivery tool collectively move along the axis. ### Claim 16 (depends on 12) The method of claim 12, wherein the external anchor has a window on an outer housing of the external anchor, wherein a distance gauge on the carriage sleeve is visible through the window for providing a user an indication of a distance of movement of the carriage sleeve. ### Claim 17 (depends on 12) The method of claim 12, wherein the delivery tool is a spinal needle. ### Claim 18 (depends on 12) The method of claim 12, wherein the external anchor system is secured to the skin surface using an adhesive.
