Probes and Biopsy 13-15
13.2 Biopsy Guide
WARNING:
The person performing biopsy procedures must understand
diagnostic ultrasound thoroughly and have been adequately
trained, otherwise the patient may suffer consequences.
In the situations listed below, the biopsy needle may fail to
penetrate the target. Incorrect biopsy may cause various
consequences for the patient.

Using a needle-guided bracket other than that provided.

Mounting the needle-guided bracket incorrectly.

Using a biopsy needle that is unsuitable for the type of biopsy
being performed.

Using a biopsy needle that is unsuitable for the needle guide.
Before and after a biopsy procedure is performed, confirm
that the needle-guided bracket is normal. Manually confirm
that the parts of the needle-guided bracket do not slip or
move from their proper positions. If the needle-guided
bracket is used when parts are not securely and correctly
installed, the patient may be injured. If an abnormality is
found on the needle-guided bracket, immediately stop using
it and contact the MINDRAY Customer Service Department or
a sales representative.
DO NOT use a needle-guided bracket while scanning is
performed. The needle may advance in an incorrect direction
and possibly injure the patient.
Never perform a biopsy during image scanning.
DO NOT freeze an image while performing a biopsy
procedure.
During biopsy procedures, the needle may deviate from the
desired course due to tissue characteristics or the type of
needle. In particular, needles with small diameters may
deviate to a greater degree.
Disinfect the probe and sterilize the needle-guided bracket
before and after each ultrasound-guided biopsy procedure is
performed. Failure to do so may cause the probe and the
needle-guided bracket to become sources of infection.
The needle mark displayed on the ultrasound image does not
indicate the actual position of the biopsy needle. Therefore, it
should only be used as a reference. Always monitor the
relative positions of the biopsy needle during procedures.
Adjust the needle mark before the biopsy procedure is
performed.
