3-2. Preparation for the biopsy attachment

Visually inspect the biopsy attachment for any break, deformation, crack or denaturalization. If you find any

damage, do not use them and contact our office written on the back cover.

3-2-2. Confirmation of the needle echo

Conduct the following procedure to confirm the needle echo before puncture. This confirmation should be done

before the sterilization of the probe and biopsy attachment.

(1) Fill a tank with water at 40 degrees Celsius, and prepare a test needle for needle echo confirmation.

(2) Connect the probe to the ultrasound diagnostic instrument. Display the puncture guideline on the image.

Refer to the documentation supplied with the ultrasound diagnostic instrument for how to display the

puncture guideline.

(3) Attach the biopsy attachment to the probe according to 4-1. Insert the test needle into the needle insertion

groove. Confirm that the needle can be smoothly inserted.

(4) Put the probe in sterile water so that needle echo is displayed.

(5) Confirm that the needle echo at each angle overlaps with the correspondent puncture guideline. Refer to the

Figure 14 for the relationship between the puncture angle and the displayed puncture guideline.
