FAQ:

Q1: What is a "Chiba Needle"? How is it different from a standard puncture needle?

A:​ Originating from Chiba University in Japan, the Chiba needle is renowned for its unique thin wall, large inner lumen, and sharp triangular tip. Compared to standard puncture needles, the Chiba needle achieves a larger inner diameter by optimizing the wall thickness while maintaining the structural strength of the cannula. This means that with the same outer diameter, a Chiba needle can extract more tissue or drain more fluid, and its sharper tip causes less tissue damage during puncture.

Q2: In which specific medical scenarios is this 16G Chiba needle primarily used?

A:​ It is widely used in interventional radiology and clinical departments, including:

1. Image-guided biopsy:​ Such as puncture sampling of solid tumors in the liver, kidneys, lungs, thyroid, and lymph nodes.

2. Drainage and aspiration:​ Catheter drainage of pleural effusion, ascites, pericardial effusion, and abscesses.

3. Medicine injection:​ Intra-articular injection, nerve block anesthesia, and local chemotherapy infusion for tumors.

Q3: Can this Chiba needle be reused?

A:​ We strongly recommend using it as a single-use sterile consumable. Although the stainless steel material itself supports high-temperature sterilization, reuse in complex clinical environments may lead to a blunted tip, bacterial growth in scratches within the lumen, or worn-out markings, thereby compromising the success rate of the puncture and patient safety. Single-use ensures maximum sterility and optimal performance.

Q4: How much discomfortable is associated with using a 16G Chiba needle during the procedure?

A:​ Although 16G is a relatively large gauge, because the Chiba needle utilizes a special triangular tip design, the puncture process is very smooth, allowing it to swiftly penetrate the epidermis and fascia, reducing the time the needle remains in the tissue. Combined with the use of local anesthesia, the patient's discomfortable is usually kept within an acceptable range, offering a much better experience than using a standard bevel needle.
