2-2. Name of each parts
The name of each part is shown in Figure 2 and the explanation for each part is listed in Table 2.
Figure 2 Name of each parts
Table 2 Name of each part and its explanation
Name Explanation
Ultrasonic radiation part Ultrasound is radiated from this part. The electronic linear transducer is
integrated underneath this part.
Front side The Insertion tube side corresponds to the side of the orientation mark on the
image.
Insertion tube The part is inserted into the patient's body with the ultrasonic irradiation area.
Transducer portion marker This indicates the position of the surface for ultrasound emission. The surface
is slightly depressed as can be conrmed by touching it.
Cable Cable transfers electric input/output signals.
Connector The connector is connected to the ultrasound diagnostic instrument.
Caution
Do not pull, bend, twist, or apply excessive force to the cable.
The probe may malfunction due to cable disconnection
Do not subject the ultrasonic radiation part to hard impact.
The impact may cause damage to the transducer, and that results in noise or no echo in the image.
In most cases, the ultrasonic radiation part itself is not damaged because the part is made of elastic
material.

3.Preparations before use
This chapter describes preparations needed to use the probe safely. Please prepare the probe prior to each use by following
the instructions below.
3-1. Visual check
Visually check the ultrasonic radiation part, insertion tube, cable and the connector.
•If any holes, indentations, abrasion, cracks, deformation, looseness, discoloration, or other abnormalities are found, do
not use the equipment.
•Gently grab the insertion tube to the ultrasonic radiation part by hand, slide it and make sure there are no catching or
loose parts.
3-2. Conrmation of cleaning, disinfection, and sterilization
Confirm that the probe is certainly cleaned, disinfected, and sterilized. The degree of reprocessing depends on the
intended use. Please refer to the separate instruction manual “Cleaning, Disinfection and Sterilization“ for cleaning,
disinfection, and sterilization procedure.
3-3. Operation check
Connect the probe to the ultrasound diagnostic instrument and check that the displayed scan type and frequency
correspond to those of the probe. Check also that there is no abnormality in the image.
Remark: Please refer to the documentation supplied with the ultrasound diagnostic instrument for how to connect the
probe and information displayed on the monitor.
If the probe is operated in still air, brightness on the top of the image may be non uniform, but this does not
affect the performance of the probe.
Warning
Make preparations prior to each use.
The operator and the patient may be injured if the equipment has any abnormality.
If any abnormality is found in the equipment, stop using it and contact our ofce written on the back
cover.

Caution
Do not use the probe if the displayed scan type and frequency do not correspond to those of the probe.
Incorrect acoustic output can result in burns or other injuries to the patient. Contact our ofce written
on the back cover.
3-4. Probe insertion check
Insert the probe into the trocar and make sure the probe can be smoothly inserted/removed.

MN1-6101 Rev. 3
4. Operation
This chapter describes the operation of the probe.
4-1. Insertion of the probe
Gently insert the tip of the probe into the insertion opening of the trocar.
Note
It is recommended to use clinical techniques from the viewpoint of a professional, with the proper judgement
on each of different cases. For the use of trocar, follow the instruction manual of trocar.
4-2. Operation
Place the ultrasonic radiation part of the probe onto the inner organ surface during surgery. An image of the region of
interest is displayed on the monitor of the ultrasound diagnostic instrument. For details on displaying and adjusting the
image, refer to the documentation supplied with the ultrasound diagnostic instrument.
Warning
Use an appropriate size trocar.
If an appropriate size trocar is not used, the probe may be damaged when inserted into the trocar. Use
a trocar with a diameter of 10 mm or more. Please refer to 3-4 for preparations before use.
Do not use a trocar with a metal valve, as it may damage the probe, when the probe is inserted.
Do not insert and operate the probe forcibly, as this may cause injury to a patient.
Insert the probe without excessive force on the probe and the cable. If the probe cannot be inserted
smoothly, stop using the probe.

MN1-6101 Rev. 3
Caution
Do not operate the probe with excessive force.
Use with excessive force could result in injury to the patient.
Scan for minimum time necessary at the lowest possible acoustic output.
Acoustic output may affect the patient’s internal tissues.
For details about the acoustic output, please refer to the documentation supplied with the ultrasound
diagnostic instrument.
Do not touch the connector terminal pin of the probe.
Electrostatic discharge may result in malfunction of the probe.
Do not touch the probe connector of the ultrasound diagnostic instrument and the patient at the same
time. It can cause electric shock to the patient.
When it is used in conjunction with a high-frequency surgical instrument, do not place the probe in the
path of high-frequency current.
The probe could be damaged, and the patient, examiner or operator could receive burns.Operate
this instrument with caution, paying attention to the positions of the counter electrode plates and the
connecting cord relative to the probe.
4-3. Pulling out the probe
Gently pull out the probe from the trocar.
Warning
When removing the probe, pull out slowly and carefully.
Do not remove the probe forcibly, as this may cause injury to a patient.
If the probe is not removed smoothly, operate it carefully and conrm endoscopically that there is no
abnormality.
Clean, disinfect and sterilize the probe if blood is adhered to the probe, otherwise there is a risk of
infection
