Last week the U.S. Patent & Trademark Office published a patent application from Google that reveals one of their next Moon Shot projects that relates to a new medical laser ablation surgery system. Google notes that "an active tracking system can be used to control a heating laser to continuously heat a target region of a biological tissue even when the target region moves relative to the heating laser."
Google states in their patent application that a number of scientific methods have been developed to destroy, damage, excise, ablate, or otherwise alter biological tissues (e.g., malignant cancerous tumors). The methods include the use of sharpened surgical implements to remove the tissues by cutting, heated surgical implements to remove, ablate, or otherwise damage the tissues by the application of high temperatures, and the application of electrical and/or electromagnetic energies (e.g., RF energy, laser light) directly or indirectly to the tissues to induce changes in the tissues through the application of heat and/or electrical fields, or through other methods. Google's invention relates and details the advancement of medical laser technology.
Google's patent FIG. 1 noted above illustrates an example active tracking system; FIG. 5 is a functional block diagram of an example active tracking system; and FIG. 6 is a flowchart of an example method.
This is a patent application that only those working in this medical field could truly appreciate. For more information on this invention, check Google's patent application 20150335385. Google filed their patent application back in May 2014. Considering that this is a patent application, the timing of such a product to market is unknown at this time.
