Overview 
1-25 
Intraoperative transducers 7LT4/7LT4s/75LT38EA/75LT40HA (Take 7LT4 as an example):   
 
No.  Name  Function 
<1>  Transducer head 
Converts the electrical signal into an ultrasonic signal, 
focusing the sound beams in a given direction; 
meanwhile, it receives the reflected ultrasonic signal 
and converts it into an electrical signal for transmission 
over the cable. The lens on the surface is the acoustic 
lens. Apply ultrasound gel on the acoustic lens for 
correct operation. 
<2> 
Needle-guided 
bracket fix 
grooves 
Mounts the needle-guided bracket using these 
grooves. 
<3>  Cable 
Transmits electrical signals between the transducer 
body and connector. 
<4>  Connector 
Connects the transducer to the ultrasonic diagnostic 
system. 
<5> 
Lock handle (not 
for 7LT4s) 
Locks the connector to the ultrasonic diagnostic 
system.
