The Wand is a computer-steered system for the painless administration of all kinds of local anesthesia. Anesthesia is applied in liquid form using special tips (needles), which the dentist injects into the selected region of the patient’s oral cavity.
The entire process is steered and monitored on an ongoing basis by an external device. The dentist’s work is facilitated by a patented sound and visual navigation system – a system of diode indicators and emitted voice instructions.
The device has a patented system for administering anesthesia with the use of the Dynamic Pressure Sensing (DPS) technology. It provides the doctor with real-time feedback on the pressure achieved at the top of the needle during anesthesia.
The pressure is read several times per second and displayed on a led pressure indicator and signaled acoustically. Information about pressure (resistance) in a given location are translated by the computer into information on the type of tissue. Identification of the type of tissue is possible because individual tissue are characterized by a specific, varying density, and thus resistance value and pressure inside the tissue.
The physiological rate of anesthesia using The Wand minimizes the risk of shock as a result of administering an imprecise and physiologically undetermined dose, as well as the danger of the anesthetic fluid entering a blood vessel. The whole anesthetic is administered at physiological rate, which enables effective and optimal absorption of the fluid by human tissues (0.005ml/sec).
The Want greatly facilitates performing a comfortable and nearly painless “injection”, i.e. the passage of the needle in the tissues, for the doctor. The agent is administered automatically, under the control of a computer, from the beginning of contact of the needle with tissues.
Drops of the administered anesthetic form an anemization layer which surrounds the needle – the anesthetic is administered continuously, both during the passage of the needle through the tissue, and after reaching the destination in the patient’s oral cavity tissues.
Drops of the anesthetic at the tip of the needle can also be used prior to first contact of the needle with tissues, which enables to perform anemization of the epithelium without additional agents.
