Embodiments disclosed herein are directed to fluid spraying apparatuses, and related systems and methods. The disclosed fluid spraying apparatuses may be used, for example, to spray a medically suitable fluid on a target region of a living subject such as for treating or removing tissue. In an embodiment, a fluid spraying apparatus includes a target designation unit having a target sensor configured to sense a target region of a living subject, a spray mechanism, and a controller. The spray mechanism includes at least one reservoir configured to hold fluid, and a spraying device operably coupled to the at least one reservoir, the spraying device configured to spray the fluid in the at least one reservoir onto the target region. The controller includes control electrical circuitry operably coupled to the spray mechanism and the target designation unit, and configured to control the spray mechanism responsive to the target sensor sensing the target region. |
