Mindray 7L4P Linear Array Probe New Original for Z Series Ultrasounds Machine Medical

►Brief Introduction

The 7L4P is an original linear array probe compatible with Mindray's Z-series ultrasound systems (such as the DC-80 Exp, Z60, Z50, Z5, and Z3), with a frequency range of 7.0 to 4.0 MHz. Utilizing a linear array transducer element, the acoustic beam is emitted in a parallel pattern, ensuring consistent lateral resolution throughout the probe area and virtually distortion-free images. This makes it ideal for precise measurements of areas such as blood vessels and tendons. It provides exceptional near-field images with exceptional detail resolution, clearly demonstrating the hierarchical structures of the skin surface, subcutaneous tissue, muscle, nerves, and blood vessels. Its excellent penetration enables diagnosis of deeper sites, such as the thyroid and breast. Brightness is uniform across the entire imaging field, with consistent image quality from edge to center, minimizing blind spots.

► How to use

1. Connecting the Probe:

Ensure the ultrasound system is in standby or off mode.
Align the connector of the 7L4P probe with the probe port on the system, insert it smoothly, and twist clockwise to lock. Never hot-swap or unplug the probe while the system is on to avoid damaging the device.

2. Applying a generous amount of coupling compound:

Apply a generous amount of ultrasound coupling compound to the probe surface and the patient's skin to be examined.

Coupon compound removes air from between the probe and the skin, ensuring effective transmission of sound waves and is crucial for obtaining clear images.

3. Optimizing Image Quality (Critical Step)
Adjust the following parameters based on your needs:
Frequency:

For very superficial structures (such as skin, subcutaneous nerves, and superficial tendons), select the highest frequency (such as 10L or 14L).
For deeper structures, if the lower part of the image is unclear, lower the frequency (such as 7M or 10M) to increase penetration.

Depth:
Use the "Depth" knob or button on the control panel.

Adjust the depth just enough to show a small amount of tissue beneath the area you are interested in. Don't go too deep or you waste screen space and slow down your frame rate.

Main Clinical Applications

1. Vascular Ultrasound: Used to assess blood flow in the carotid arteries and limb arteries and veins, and to diagnose plaques, thrombi, vascular stenosis, and other conditions. Clear images facilitate precise measurements.

2. Superficial Small Organs:

Thyroid: Clearly displays thyroid parenchyma, nodule boundaries, internal structures, and blood flow signals.

Breast: Used for preliminary screening and assessment of breast masses, especially for superficial lesions in dense breasts.

Testicle: Used for diagnosis of testicular torsion, epididymitis, and varicocele.

3. Musculoskeletal System:

Precisely images muscles, tendons, ligaments, and nerves for diagnosis of tears, inflammation, and entrapment syndromes (such as carpal tunnel syndrome).

4. Pediatrics and Interventional Guidance:

Suitable for examinations of the hip joint, brain, and other areas in infants and young children.

Performs procedures such as puncture biopsies and nerve blocks under real-time ultrasound guidance, providing precise positioning.
