Abstract
Disclosed is an ultrasonic transducer probe for extracting tissues or body fluids from internal body organs for diagnostic purposes, in which a cannula guide slot portion is formed separately from a carrier body on which transducer elements are arranged, whereby the cannula guide slot portion may be sterilized independently and fitted in the carrier body as required for use.
Claims12
An ultrasonic transducer probe for use in injecting a cannula through a region of a subject to be examined comprising:
- a carrier with a plurality of ultrasonic transducer elements arranged proximate to an application surface of said carrier adapted to be positioned on the body surface of the subject,
- a guide cavity formed in said carrier, said guide cavity extending to said application surface to form an application opening in said application surface proximate to said transducer elements,
- a cannula guide block sized to removably and securedly fit within said guide cavity and having at least one guide slot bored therethrough for guiding the cannula, said guide slot communicating with the application opening in said application surface but not communicating with any portion of said carrier itself when said cannula guide block is fit within said guide cavity, and
- a slit communicating with said guide slot along its full length and further communicating with the exterior of said carrier to permit the removal of said ultrasonic transducer probe from the subject after a cannula is inserted through said probe and into the body of the subject,
- whereby the cannula guide block can be removed from said carrier and sterilized independently of said carrier.

- a guide cavity formed in said carrier, said guide cavity extending to said application surface to form an application opening in said application surface proximate to said transducer elements, and
- a cannula guide block sized to removably and securedly fit within said guide cavity and having a plurality of radially extending guide slots bored therethrough for guiding the cannula, said guide slots being focused to intersect at one point beyond said application surface to allow a user to introduce the cannula from a selected radial position and communicating with the application opening in said application surface but not communicating with any portion of said carrier itself when said cannula guide block is fit within said guide cavity,
- whereby the cannula guide block can be removed from said carrier and sterilized independently of said carrier.
