Systems and methods for safe, precise stereotactic implantation
The present disclosure relates generally to precise stereotactic implantation of an instrument (e.g., a recording electrode, a stimulating electrode, a biopsy instrument, a catheter, a delivery device, and the like) into a target area in a patient's brain. As such, one aspect of the present disclosure can relate to a stereotactic device that can be used to accomplish the precise implantation of the instrument. The stereotactic device can include a body to secure the stereotactic device to the patient's head. In some instances, the body can have a u-shape. The stereotactic device can also include a guide attached between sides of the body to move an instrument holder into place above a target area. The guide can be locked in position to lock the instrument holder in the place to facilitate injection of the instrument into the target area.
1. A method comprising:
fixing a stereotactic device to a frame attached to a patient's head, wherein the stereotactic device comprises:
a body having a U-shape and comprising two sides separated by a distance; and
a guide extending from one of the two sides of the body to another of the two sides of the body, wherein the guide is lockable at a position between the two sides and a portion of the guide is rotatable;
performing a coarse movement of the guide to a position along the two sides,
wherein the position is above a target area within the patient's head;
locking the guide at the position;
performing a fine adjustment of an instrument holder attached to the guide by linear and/or rotational movement;
locking the instrument holder in place after the fine adjustment;
implanting a medical instrument to the target area within the patient's head through the instrument holder attached to the guide;
unlocking the guide;
performing another coarse movement of the guide to a second position along the two sides, wherein the second position is above a second target area within the patient's head;
locking the guide at the second position;
performing another fine adjustment of the instrument holder attached to the guide by linear and/or rotational movement;
locking the instrument holder in place after the other fine adjustment; and
implanting a second medical instrument to the second target area within the patient's head through the instrument holder attached to the guide.
2. The method of claim 1 , wherein the body remains fixed as the guide is moved to the second location.
3. The method of claim 1 , wherein the first target area and the second target area are orthogonal to each other.
4. The method of claim 1 , wherein the implantations of the medical instruments to the target areas are achieved according to different lateral trajectories.
5. The method of claim 1 , wherein the medical instrument is at least one of a recording electrode, a stimulating electrode, a biopsy instrument, a catheter, and a drug delivery device.
