The Wand is an American computer-controlled system for the injection of local anaesthetic. It consists of a computer-controlled drive unit and a separate single-use disposable hand piece/needle assembly. Compared to the syringe, the Wand system makes an application of anesthetic significantly more comfortable for both a patient and a doctor.
How does it work?
There are a few reasons why injections can be unpleasant. One of the main factors is a concentration of a local anesthetic in the small space before its application to the tissue. Anesthetic which is applied too rapidly can be a source of pain. Another unpleasant consequences of anesthetic application is a collateral numbness which can remain several hours after the treatment.
The Wand device is designed to regulate the current and exact amount of anesthetic which enables to increase the preciseness of application and reduces the numbed area. The Wand system helps the patient to relax before, during and after the procedure.
