13-4 Probes and Biopsy
13.1.2 Laparoscopic Probe
Overview
Operates on the probe deflection.
Controls up/down deflection of the distal tip.
Left/Right deflection lever
Controls left/right deflection of the distal tip.
Used to control the deflection of distal tip.
Distal tip with transducer
Converts the electrical signal to an ultrasonic signal,
focusing the sound beams in a given direction while it
receives the reflected ultrasonic signal and converts it to an
electrical signal for transmission over the cable. The lens on
the surface is the acoustic lens.
Mechanical dimensions
Max. shaft external diameter: ≤10.2 mm
Working length (total length of Hard shalf, flexible shaft and distal tip): 338±3% mm
Lever Operations
Check the proper mechanical operation of the probe. Rotate the scan plane with the deflection
levers on the handle. Make sure that the rotation is smooth for all scan planes. Deflect the tip in
both up/down and left/right direction using the deflection levers on the handle. Make sure the
deflection operates smoothly.
The up/down and/or left/right deflection may, after prolonged use, develop an unwanted amount of
free play. In that case, contact the service organization to re-adjust the steering of the probe.
The flexible shaft can be deflected up to 90° (tolerance: -5°~10°) in four planes of up, down, left
and right. Use the 2 deflection levers to adjust the distal tip with transducer as the following figure.
