13-14 Probes and Biopsy 
13.2  Biopsy Guide 
WARNING:
1.  The person performing biopsy procedures must 
understand diagnostic ultrasound thoroughly and have 
been trained adequately, otherwise, side effects may be 
caused to the patient. 
 
2.  In situations listed below, the biopsy needle may fail to 
penetrate the target. The incorrect biopsy may cause 
various side effects in the patient. 
Use a needle-guided bracket other than that provided. 
Mount the needle-guided bracket incorrectly. 
Use a biopsy needle that is unsuitable for the type of 
biopsy being performed. 
Use a biopsy needle or guiding block that is unsuitable 
for the needle guide. 
 
3.  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 off 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 MINDRAY Customer Service Department or 
sales representative. 
 
4.  DO NOT use a needle-guided bracket when scanning is 
performed. The needle may advance in an incorrect 
direction and possibly injure the patient.   
Never perform a biopsy during image scanning. 
 
5.  DO NOT freeze an image while performing biopsy 
procedure. 
 
6.  During biopsy procedures, the needle may deviate from 
the desired course due to the tissue characteristics or 
the type of needle. In particular, needles of small 
diameters may deviate to a greater degree. 
 
7.  Disinfect the probe and sterilize needle-guided bracket 
before and after each ultrasound-guided biopsy 
procedure is performed. Fail to do so may cause the 
probe and the needle-guided bracket become sources 
of infection. 
 
8. 
 
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 the procedures. 
 
9.  Adjust the needle mark before the biopsy procedure is 
performed.
