18. Needle Mark
In this system, it is possible to display the needle mark for the specified biopsy adapter
on the screen.
Contact your TOSHIBA service representative for details of the needle mark display
ON/OFF switch.
When performing a biopsy procedure, be extremely careful to avoid tissue damage,
neurological injury, or infection.
The clinical procedures should be selected based on specialized medical judgment.
WARNING:
1. Ultrasound-guided biopsy procedures require a thorough
understanding of ultrasound diagnosis and specialized
training in biopsy procedures. If biopsy procedures are
performed without sufficient knowledge or training, they
may be performed incorrectly and the patient may be
injured.
2. In the situations listed below, the biopsy needle may fail
to reach the target lesion. Incorrect biopsy may harm the
patient.
(a) A defective biopsy adapter is used.
(b) A biopsy adapter other than that specified is used.
(c) The biopsy adapter is mounted incorrectly.
(d) A biopsy needle that is unsuitable for biopsy is used.
(e) A biopsy needle that does not match the biopsy
adapter is used.
(f) The operator continues the biopsy procedure when
the image is frozen.
(g) The operator does not correctly observe the location
of the needle tip.
(h) The selected needle mark angle does not match the
angle indicated on the biopsy adapter to be used.
3. Keeping the following points in mind, carefully monitor
the target region and the needle tip while performing a
biopsy procedure.
(a) During a biopsy procedure, the needle may deviate
from the desired course due to the tissue
characteristics or the type of needle. In particular,
needles with small diameters may deviate to a greater
degree.
(b) The biopsy target may shift due to unexpected patient
motion when the biopsy needle is inserted or due to
respiratory movement.
(c) The needle mark displayed on the ultrasound image
indicates the predicted course of the biopsy needle,
not the actual position of the biopsy needle. It should
be used only for reference.
