Abstract

An arrangement for the puncturing of internal body organs, vessels or the like, through the utilization of a puncturing cannula or hollow needle which will well reflect an ultrasound, as well as an ultrasound-echo sectional view apparatus having an ultrasonic applicator with an ultrasound scanning system for the surface-wide ultrasonic scanning of the body region which is to be punctured, and a display or viewing apparatus for rendering visible the echo-section images. On viewing apparatus, a targeting aid for the aiming of a suitable punctuating point in the echo sectional view, and on the ultrasound applicator a guide aide adjustable at least in the targeting direction of the aiming aside for the introduction of the puncturing cannula into the body region which is to be punctured.

Claims

1. An ultrasonic surgical device for puncturing the body of a patient comprising

an ultra sound applicator including a housing and an ultrasonic beam transmitter positioned within said housing for scanning a beam toward a region of the body of the patient, viewing means operatively associated with said ultrasound applicator and including a housing and a viewing screen for producing an image of the region of the body being scanned, with the image being located with respect to said viewing means housing at a position corresponding to the location of the applicator housing with respect to the region of the body being scanned,

an elongated aiming pin, pin mounting means for adjustably mounting said aiming pin on said viewing means housing and for releasably locking same in place with respect thereto,

said aiming pin having a distal end movable in overlying relation with respect to said viewing screen, said pin mounting means having means for ascertaining the position of said distal end of said aiming pin relative to said viewing means housing

an elongated puncturing cannula, and cannula mounting means for adjustably mounting said cannula on said ultrasound applicator housing and for releasably locking same in place with respect thereto,

said cannula having a distal end movable with respect to said ultrasound applicator housing to reach the region of the body being scanned, said cannula mounting means having means for ascertaining the position of said distal of said cannula relative to said ultrasound applicator housing, and said aiming pin and said pin mounting means, and said cannula and said cannula mounting means, being disposed relative to their respective housings such that the location of the distal end of the aiming pin with respect to the viewing means housing can be duplicated with respect to the location of the distal end of the cannula with respect to the ultrasound applicator housing.

2. The invention as defined in claim 1 wherein said aiming pin and said cannula each comprise means forming displacement scales along the length thereof.

3. The invention as defined in claim 1 wherein said aiming pin mounting means and said cannula mounting means each comprise means forming an angle scale.

4. The invention as defined in claim 1 wherein said pin mounting means and said cannula mounting means each comprise a pivotal tubular guide sleeve and an adjustable locking knob for locking said guide sleeve in position.
