摘要： An apparatus and method for injecting a drug into a precisely selected location in a patient's body which is a combination scanner and drug injector. The scanner is a planar array of ultrasonic transducers which transmits a focused ultrasonic beam over the entire region of interest. The injector is preferably a hypodermic syringe mounted with the array on a base. The syringe is mounted to slide between one position where the injector conduit is retracted from the patient and another position where the adjustably positioned exit end of the conduit is in the desired location for injection of the drug. As the operator holds the scanner-injector against the patient's body with injector conduit retracted, he views on a monitor screen a virtual image of the conduit which is the image of the conduit after the conduit is injected into the body. The operator electronically adjusts the length of the virtual image and adjusts the position of the scanner-injector so that the exit tip of the virtual image is located at the desired location of the image of the region on the screen. Then the conduit is inserted into the body up to a length where the exit tip of the injector is at the desired location. Then the drug is injected into the patient. In another application of the apparatus and methods of the invention, a vacuum source is attached to the injector conduit and the device is used to aspirate fluids. instead of a drug In another embodiment, a portion of the ukltrasonic beam is focused on the region of interest before and during insertion of the conduit and drug to facilitate entry of the drug into the region of interest.
