Read moreIn the domain of interventional diagnostics, a Tru-Cut Biopsy Needle is a highly precise instrument used by clinicians to extract core tissue samples under imaging guidance. INI as one of the Biopsy Needle Suppliers, we design, manufacture, and deliver Disposable Biopsy Needle products to medical device partners, hospitals, and clinical labs.
A Tru-Cut Biopsy Needle is a type of core biopsy instrument, often incorporating a cutting cannula and a stylet, which allows retrieval of a small cylindrical core of tissue. It is commonly used in soft tissue sites (such as breast, liver, kidney, lymph node) under guidance (e.g. ultrasound or CT). The device typically includes a specimen notch on the cutting cannula, depth markings, and a removable stylet for multiple insertions. The design aims to allow clinicians to obtain intact core samples with controlled mechanical action.
As a manufacturer, we produce Disposable Biopsy Needle units intended for single use. Because they are pre-sterilized and individually packaged, they reduce cross-contamination risk and simplify workflow in clinical settings. Our disposable models remove the need for reprocessing and align with standard medical device practices. Every unit is quality tested, sterilized, and sealed to preserve sterility until use.
As Biopsy Needle Suppliers, we offer a broad portfolio of Tru-Cut Biopsy Needle variants, including:
We also offer optional customizations (OEM/ODM) for clients who need proprietary hub geometry, packaging, or branding.
From a factory's perspective, producing a high-quality Tru-Cut Biopsy Needle or Disposable Biopsy Needle involves the following key steps:
Here are some common questions from clients and how we answer them, in our role as Biopsy Needle Suppliers:
Q: How do you ensure consistent core sample length?
A: We precisely machine the specimen notch length and control cannula tolerances. Our inspection systems measure the notch and verify fit between cannula and stylet to yield consistent core capture length.
Q: Can you reduce trauma or deformation of the sample?
A: Our Tru-Cut Biopsy Needle designs include sharp scalpel-like edges and smooth internal surfaces, minimizing drag or tearing during tissue capture.
Q: How is sterility assured in disposable models?
A: Each Disposable Biopsy Needle unit is individually sealed and sterilized using validated sterilization processes. We maintain complete traceability of each lot.
Q: Can you support custom designs?
A: Yes. As Biopsy Needle Suppliers, we provide OEM/ODM service. If you need a special hub, connector, or marking scheme, we can adapt tooling and production to your requirements.
