Konica Minolta SONIMAGE HS2 - 8.2 Biopsy Safety and Precautions

256
Biopsy refers to a study procedure that surgically ob-
tains a tissue sample from a part of a patient’s body.
When conducting any biopsy procedure using the
ultrasound system, attaching the biopsy bracket and
needle guide to the transducer allows you to check the
angle and direction of the applicable biopsy needle
during the procedure.
Displaying the image of the biopsy needle being in-
serted into the body in real time, the ultrasound system
helps minimize risks to your patient.
8.2.1 Safety Precautions &
Warnings for Biopsy
When performing a biopsy procedure, use an ap-
proved biopsy bracket and needle guide.
Biopsy procedures should always be performed with
caution to prevent any complications.
It is recommended to use a sterile cover and gel dur-
ing the procedure.
WARNING
•••••••••••••••••••••••••••••••••••••
• Do not perform biopsy procedures when the sys-
tem is in battery mode. The unit may shut down
unexpectedly causing potential harm to the patient.
• Do not freeze the image when performing a biopsy
procedure. Biopsy procedures may be performed
incorrectly during a frozen image. Do not reuse the
needle guide.
• Ultrasound guided procedures should be per-
formed by a trained physician in accordance with
prevailing medical standards otherwise serious
complications may arise.
• To prevent injury to the patient confirm before
the exam that there are no abnormalities with the
bracket and it properly ts on the transducer.
• Always monitor the biopsy target and the biopsy
needle end while performing a biopsy procedure.
– 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.
– The biopsy target may shift due to unexpected
patient motion when the biopsy needle is inserted,
or due to respiratory movement.
– The biopsy guide displayed on the ultrasound
image does not indicate the actual position of
the biopsy needle. It should only be used as a
reference.

WARNING
•••••••••••••••••••••••••••••••••••••
• Disinfect the transducer and biopsy bracket before
and after an ultrasound-guided biopsy procedure.
For instructions on how to disinfect the transducer,
refer to "8.1.6 Cleaning and Disinfection". For in-
structions on how to disinfect the biopsy bracket,
refer to the instruction manual of the biopsy brack-
et. Failure to do so may result in the transducer
and biopsy bracket becoming sources of infection.
• Before a biopsy procedure is performed, confirm
that the selected biopsy guide angle matches the
angle indicated on the biopsy bracket to be used.
Patient injury may result if they are not aligned.
• Before starting a biopsy procedure, conrm the
insertion route of a biopsy needle.
Use the following procedure to make sure that the
insertion route of the biopsy needle ts properly
within the range of the biopsy guideline displayed
on the screen:
– Attach an appropriate biopsy bracket and needle
guide to the transducer.
– Perform a scan in a container lled with water (room
temperature).
– Display the biopsy guideline on the screen.
– Insert a biopsy needle into the needle guide, make
sure the echo from the biopsy needle ts within the
biopsy guideline range.
• Do not perform the biopsy during the pressurization
state.
– Do not perform the biopsy during pressurization of
human tissue in Elastography-mode, etc. There is
a risk of scarring the patient.
• It is possible to use it for a nerve block injection
or biopsy procedure; however, avoid puncturing
the transducer covers with an injection or biopsy
needle. Otherwise, there is a possibility that the
transducer covers are broken and some parts of
broken transducer covers enter the patient's body
or that the needle is clogged.
• Do not expose the transducer to uids that contain
organic solvents (excluding, however, the cleaners
and disinfectants described in this manual).
Doing so may damage it. There is also a risk of
electric shock.
