Leltek LU710E

The LU710E fits pelvic and urological examination rooms where the probe stays with the patient and the screen sits separately. Leltek specifies a compatible phone, tablet or computer as the display. The 370 × 74 × 40 mm scanner weighs 412 g with its battery, giving the room a handheld imaging component alongside the couch, viewing device and charging point.

Gynaecology services use the Pelvis preset as an initial configuration for pelvic assessment, with transvaginal scanning within the indicated scope. Early pregnancy assessment has its own OB Early preset and early-obstetric measurement function. The 151° field and adjustable depth, up to 15 cm, define the displayed scan plane. Measurements and retained images record the selected anatomy within the patient study.

Urology departments can select Urology and Prostate presets for the relevant examination. Transrectal imaging is an indicated application, and optional colour, power and pulsed wave Doppler add flow views to the configured system. The optional manufacturer-compatible endocavity needle guide accepts 16–18 gauge needles and attaches to the transducer with a 2° guidance angle. The app presents the acquired image on the paired display.

Within hospital and outpatient services, trained clinicians can also use its wider fetal, general abdominal, paediatric, small-organ and freehand interventional guidance scope. The room's routine combines protective sheaths and coupling gel with cleaning followed by high-level disinfection for endocavity use. Battery recharging and the 30-minute use/10-minute rest cycle are part of that arrangement. Optional DICOM carries recorded images into a configured server workflow.

An examination setup with a separate display

The endocavity probe and its viewing device are positioned separately within the examination area. Leltek specifies a direct Wi-Fi connection to compatible phones, tablets and computers. This arrangement lets the display stay within the clinician's view while the 412 g probe stays at the examination site. The app places imaging controls, retained views and study information on that screen.

Pelvic and urological starting settings

Four presets organise the scanner around Pelvis, OB Early, Urology and Prostate examinations. Each provides initial imaging parameters for its named application. The clinician can then adjust depth, frequency and brightness around the acquired view. User-created presets preserve those adjustments for subsequent examinations.

A curved view for cavity examinations

A 10 mm curvature radius shapes the scanning head, and the resulting ultrasound field spans 151°. The displayed depth can extend to 15 cm. These figures describe the region available for framing the chosen anatomy during transvaginal or transrectal assessment. The operator selects the scan plane by positioning the probe, with image controls to adjust tissue appearance.

Measurements kept with the retained image

Distance callipers and ellipse measurements place dimensions on a selected ultrasound view. Text and position marks provide anatomical reference for those measurements within the study. Early obstetric measurement support also forms part of the endocavity application. Keeping the marked view keeps the measurement alongside the image it was taken from, so the examination record preserves both the anatomy and its dimensional assessment.

Flow information as a configured option

With optional colour Doppler, a selected region shows detected flow over the anatomical picture. Power Doppler shows the strength of the Doppler signal, and pulsed wave Doppler provides a velocity trace from a selected sample location. These two modes are also optional. Their controls let you record flow information alongside the structural image for a configured pelvic or urological examination.

A mechanical guide for selected procedures

Leltek specifies an optional stainless-steel endocavity needle guide with a 2° biopsy angle and compatibility with 16–18 gauge needles. The guide attaches to the probe and provides physical support for the needle during supported tissue biopsy procedures. It weighs 40 g and measures 171 × 32 × 36 mm. The guide is a reusable component.

Examination records beyond the live screen

The app can retain still images, video sequences and a PDF report from the examination. Its 200-frame cine buffer supplies recent views for selection after image freeze. The recorded material remains associated with the patient study. Optional DICOM exchange adds a route for image transfer to a compatible archive, placing the acquired views in the wider imaging record.

Power managed within the examination area

A rechargeable 6000 mAh battery powers the probe, and USB charging accepts up to 15 W. Approximate endurance ranges from 2.5 to 4.5 hours per charge across imaging modes. After up to 30 minutes of use, the scanner requires a 10-minute rest interval. A manufacturer-compatible charging dock is an optional place for the unit between examinations.

Reprocessing matched to mucosal contact

Protective sheaths and compatible ultrasound gel accompany transvaginal and transrectal scanning. After mucous-membrane contact, the semi-critical probe requires cleaning followed by high-level disinfection before reuse. This requirement places reprocessing alongside imaging and charging in the department's equipment routine.

Endocavity imaging for pelvic examinations

A 151° field presents the scan plane around the endocavity head. The array has 128 elements, a 10 mm curvature radius, and a frequency bandwidth of 3.6–8.5 MHz. Imaging depth extends to 15 cm. This arrangement supports pelvic and urological applications, with the displayed depth selected around the structures being examined via transvaginal or transrectal approaches.

Four clinical preset starting points

The LU710E's named presets are Pelvis, OB Early, Urology, and Prostate. Their initial settings place the examination type within the app's imaging setup. The operator can then adjust the image and retain a chosen configuration as a custom preset. In a pelvic or urology examination room, this provides application-specific starting points within the same handheld scanning system.

B-mode anatomy and M-mode movement

Structures appear as a two-dimensional greyscale image in B-mode. M-mode follows changes along one selected ultrasound line, with depth on one axis and time on the other. Both are included in the standard configuration. The anatomical image and motion display therefore provide different views of the chosen tissue, while the app keeps the relevant controls beside the examination image.

Optional colour, power and pulsed wave Doppler

The flow-imaging options comprise colour Doppler, power Doppler and pulsed wave Doppler. Colour overlays depict flow within an adjustable region of the structural image. Power Doppler represents the strength of the detected flow signal. Pulsed wave Doppler displays velocity from a selected sample location, with adjustable gate size, angle correction, and baseline for flow examination.

Controls for depth and brightness

The displayed field can be set to an imaging depth of up to 15 cm. Gain controls overall brightness, while time gain compensation changes brightness at selected depths through the image. Frequency adjustment operates within the probe's 3.6–8.5 MHz band. Together, these controls let the clinician configure the appearance of pelvic or prostate anatomy as the scan plane changes.

Harmonic imaging and display processing

Endocavity imaging includes tissue harmonic imaging, which uses returning echoes at multiples of the transmitted frequency. The B-mode display has 256 shades of grey. Dynamic range and grey-map controls shape how echo intensity is represented, while persistence averages successive frames. Line density, image enhancement, energy-saving, and normal or high-performance frame-rate settings provide further control over the displayed image.

Early obstetric and general measurement tools

The endocavity probe supports early obstetric measurement, and it includes an automatic measurement tool. General image measurements cover distance, ellipse area and ellipse perimeter. These tools operate alongside text annotations, arrows and body marks on retained views. The resulting image can carry both the selected anatomical reference and its measurements into the patient study or a PDF examination report.

Wireless display arrangements

Leltek specifies compatible phones, tablets and computers running Android, iOS or Windows, with iOS 15 or later for the current iOS app. A direct Wi-Fi connection carries the scan to the viewing device at 2.4 or 5 GHz. This places the display separately from the probe in the examination room. USB also provides a cable connection for data.

Probe controls and status lights

The complete unit measures 370 × 74 × 40 mm and weighs 412 g with its battery. Power and freeze buttons remain on the handheld housing during scanning. A freeze press pauses or resumes the live image, while coloured indicators show power, wireless connection, charging, and low-battery states. The housing also includes a cooling fan to dissipate heat.

Retained frames and adjustable video

After the image is frozen, a buffer of the latest 200 frames remains available. The operator can move through the sequence, select a frame and add measurements or annotations. Part of the sequence can become a video clip. Clip duration is adjustable from the three-second default, preserving movement around a selected point in the examination.

Patient records and report formats

Each patient study holds its associated still images and video clips. JPG, PNG and BMP serve as still-image export formats, while recorded video uses MP4. A PDF report brings together patient details, selected images, measurements, annotations, a signature, and the date. These outputs retain the captured view, its descriptive markings and the relevant examination information in different file formats.

Optional DICOM transfer and worklists

DICOM 3.0 is an optional interface for exchanging medical images. Leltek specifies image export, upload to a DICOM server and retrieval of examination information through a worklist. The saved image carries study-related information into a compatible imaging system. This gives the handheld scanner a route into an image archive while the app also retains its standard image, video and PDF outputs.

Rechargeable power and working periods

An integrated lithium-ion battery provides 6000 mAh of capacity and is rated for 300 discharge cycles. Approximate endurance per charge is 4.5 hours in B-mode or M-mode. Optional colour and power Doppler run for about 3.5 hours, and optional pulsed wave Doppler for about 2.5 hours. The operating period is up to 30 minutes, paired with a 10-minute rest interval.

USB charging and a compatible dock

Between scanning sessions, USB supplies charging power up to 15 W at 5 V DC and up to 3 A. Leltek also specifies an optional compatible charging dock. The dock accepts 100–240 V AC at 50/60 Hz and provides 5 V DC at 2 A. A blue light indicates charging and turns off when fully charged, making the charging state visible.

Optional endocavity needle guide

Leltek specifies the optional M-As04-1003-A/B endocavity guide for use with the scanner's series. Its medical-grade, corrosion-resistant stainless steel construction supports the needle mechanically when attached to the probe. The guide has a 2° angle and accommodates 16–18 gauge needles. It measures 171 × 32 × 36 mm (height × width × depth), weighs 40 g, and is reusable.

Covers and between-patient reprocessing

Transvaginal and transrectal examinations use a protective transducer sheath, with compatible ultrasound gel providing acoustic coupling. The endocavity transducer is classed as semi-critical because it contacts mucous membranes. Between patients, reprocessing comprises cleaning followed by high-level disinfection. Sheaths, coupling gel and the reprocessing area therefore form part of the examination setup alongside the probe, viewing device and charging provision.

The LU710E fits gynaecology and urology services that organise endocavity scanning around an examination couch and a separate display. Its pelvic, early obstetric and prostate settings give the handheld system a defined workload within those rooms. The reusable format has practical requirements: compatible covers and gel accompany cavity examinations, and cleaning, followed by high-level disinfection, prepares the probe for the next patient. Charging and the specified operating cycle are also part of its use. Optional Doppler and needle-guide configurations support the selected examination or procedure. Images, measurements and recordings stay associated with the patient study. The complete unit is 370 mm long and weighs 412 g with its battery.
