About Biopsy & Aspiration Needles
Biopsy and aspiration needles let clinicians collect tissue, cells, or bone marrow for diagnosis with as little disruption to the patient as possible. This category covers BD core biopsy instruments and needles, coaxial introducer needles, vacuum-assisted breast biopsy systems, Chiba fine needle aspiration needles, and Jamshidi and Illinois bone marrow biopsy and aspiration needles and trays. Products are listed by gauge and length so you can match them to the target and the approach. Interventional radiologists, oncologists, hematologists, breast surgeons, and procedure nurses rely on these devices in hospitals, imaging centers, and outpatient clinics. Whether you are restocking a single gauge or setting up a new biopsy program, you can compare sizes and configurations side by side here.
Why Biopsy & Aspiration Needles Are Essential
A diagnosis often comes down to a small sample. When imaging shows a suspicious mass, an enlarged node, or abnormal blood counts, a biopsy or aspiration is frequently the step that tells the care team what they are dealing with. The quality of that sample shapes how quickly and confidently a pathologist can answer.
The right needle makes a real difference. A core needle collects a strip of intact tissue for architecture. A fine aspiration needle gathers cells through a thin bore. A bone marrow needle is built to pass through cortical bone. Choosing the correct gauge, length, and mechanism helps the clinician reach the target and collect an adequate specimen.
For patients, these procedures come with real worry. A well-matched needle and a smooth procedure can mean fewer passes, less waiting, and a clearer path to treatment. That is why dependable supplies matter to everyone in the room.
What Are Biopsy & Aspiration Needles?
Biopsy and aspiration needles are specialized needles designed to remove a sample of tissue, cells, fluid, or marrow from the body for laboratory analysis. Core biopsy devices use a spring-loaded or manually advanced mechanism with an inner notched stylet and an outer cutting cannula to capture a tissue core. Fine needle aspiration needles, such as Chiba needles, are thin needles with a stylet that are used with suction to draw out cells.
Coaxial introducer needles create a pathway so the biopsy needle can be passed more than once through a single skin entry. Bone marrow needles have a sturdy handle and stylet to penetrate bone and collect marrow aspirate or a core.
Types of Biopsy & Aspiration Needles
1. Disposable Core Biopsy Instruments
Best for: Image-guided soft tissue biopsies where a single-use, all-in-one device is preferred.
Disposable core biopsy instruments combine the firing mechanism and needle in one sterile, single-use device. BD offers several lines in this category. The Mission instrument is listed as semi-automatic and comes in 14, 16, 18, and 20 gauge with needle lengths from 6 cm to 25 cm. Max-Core is listed as auto firing in 14G–20G and 10–25 cm lengths. Marquee instruments offer adjustable depth with dual firing in 12G–20G.
Semi-automatic devices let the operator advance the stylet and check its position before firing the cutting cannula. Automatic devices fire both stages in sequence. Your choice depends on the target, the operator’s preference, and your department’s protocol.
Key Features
- Each instrument is single-use and supplied sterile.
- Semi-automatic, automatic, and dual-firing options are available.
- Gauges range from 12G to 20G depending on the line.
- Needle lengths range from 6 cm to 25 cm.
Applications
- Ultrasound- or CT-guided biopsies of soft tissue masses.
- Core sampling of lymph nodes and organ lesions as directed by the physician.
- Departments that prefer disposable devices to avoid reprocessing.
2. Core Biopsy Instrument Kits with Coaxial Cannula
Best for: Procedures where several cores may be collected through one access point.
BD Mission disposable core biopsy instrument kits pair the biopsy instrument with a coaxial introducer that is one gauge larger. Examples include an 18G needle with a 17G coaxial, a 20G needle with a 19G coaxial, and a 14G needle with a 13G coaxial. Needle lengths in these kits include 10, 16, 20, and 25 cm, and several listings specify the coaxial length, such as 7.8, 13.8, or 17.8 cm.
The BD Marquee disposable core biopsy kit also includes a coaxial cannula, with adjustable depth in 12G–20G and 10–25 cm options. Packaging the instrument and introducer together helps make sure the sizes are matched.
Key Features
- Each kit includes a matched biopsy instrument and coaxial introducer.
- The coaxial is sized one gauge larger than the biopsy needle.
- Listings state both the needle length and the coaxial length.
- Kits are designed for single use.
Applications
- Collecting multiple core samples through a single skin entry.
- Deeper targets where maintaining the access path is helpful.
- Standardizing kit contents across a biopsy service.
3. Reusable Core Biopsy Instruments and Compatible Needles
Best for: Facilities that want a durable biopsy gun with interchangeable disposable needles.
The BD Magnum core biopsy instrument is a reusable device with adjustable 15 mm or 22 mm penetration depth and one-handed operation. It is listed as compatible with TruGuide coaxial needles. Magnum core biopsy needles are sold separately in 12G–20G and 10–30 cm lengths and are listed as sterile and coaxial compatible.
Because the handle is reused, it must be cleaned and reprocessed between patients according to the manufacturer’s instructions and your facility’s protocol. The needles themselves are single-use.
Key Features
- The reusable instrument offers two depth settings.
- The design is listed for one-handed use.
- Disposable Magnum needles come in a range of gauges and lengths.
- The system is compatible with TruGuide coaxial needles.
Applications
- Busy biopsy services that perform frequent core procedures.
- Programs that want to stock needles separately from the firing device.
- Procedures where the operator prefers a familiar reusable handpiece.
4. Coaxial Introducer Needles
Best for: Creating a stable access path for repeat biopsy passes.
The BD TruGuide coaxial biopsy needle is listed as compatible with Max-Core, Mission, and Magnum devices. The example in this category is 15 gauge in lengths of 7.8 to 13.8 cm and is single-use.
A coaxial introducer is placed near the target first. The biopsy needle is then passed through it, and the introducer stays in place between passes. Confirm that the coaxial gauge and length match the biopsy needle you plan to use, since the biopsy needle must fit through and extend beyond the introducer.
Key Features
- The introducer is compatible with several BD core biopsy lines.
- Each needle is single-use.
- Listings specify gauge and usable length.
Applications
- Multiple-pass core biopsies through one entry site.
- Pairing with separately purchased Magnum, Mission, or Max-Core needles.
- Image-guided procedures where re-imaging the target between passes is useful.
5. Vacuum-Assisted Breast Biopsy Systems
Best for: Ultrasound-guided breast biopsies that call for larger samples.
The BD EleVation breast biopsy system is described as a handheld, vacuum-assisted, ultrasound-guided device. It uses a rechargeable, reusable driver with an LED display and single-use probes in 10G, 12G, and 14G sizes. The driver, the system, and the probes are listed separately so you can order what you need.
Vacuum assistance draws tissue into the sampling chamber before it is cut. The larger probe sizes are designed to collect bigger samples than a standard core needle. Follow BD’s instructions for use and your facility’s breast imaging protocol.
Key Features
- The system is handheld and designed for ultrasound guidance.
- The driver is rechargeable and reusable.
- Single-use probes are available in 10G, 12G, and 14G.
- The driver includes an LED display.
Applications

When to Use Biopsy & Aspiration Needles
These devices are used when a physician orders a tissue, cell, or marrow sample to support a diagnosis. The specific device depends on the type of sample needed and where the target sits.
- Core biopsy: when a solid lesion needs a tissue sample that preserves structure.
- Fine needle aspiration: when cells or fluid are needed for cytology.
- Vacuum-assisted biopsy: when larger breast tissue samples are planned under ultrasound.
- Coaxial technique: when several passes through one entry site are expected.
- Bone marrow procedures: when marrow aspirate or a marrow core is ordered.
Procedures are performed by trained clinicians according to physician orders and facility protocol.
How to Use Biopsy & Aspiration Needles
These steps are a general overview for supply planning, not procedural instruction. Always follow the manufacturer’s instructions for use and your facility’s protocol.
- Confirm the physician order, the planned approach, and the device type, gauge, and length.
- Check packaging for integrity and expiration, and gather any matching coaxial introducer, driver, or tray.
- Prepare the site and maintain aseptic or sterile technique as required.
- Use imaging guidance as planned to position the needle near the target.
- Collect the sample with the device’s firing, vacuum, or aspiration mechanism as instructed.
- Handle and label specimens according to laboratory requirements.
- Activate any safety features and dispose of sharps in an approved sharps container.

Benefits of Biopsy & Aspiration Needles
1. Samples Matched to the Diagnostic Question
Core needles, aspiration needles, and marrow needles each collect a different kind of sample. Having all three available lets the care team choose the device that fits what the pathologist needs.
2. Fewer Skin Entries with Coaxial Technique
Coaxial introducers let clinicians take several samples through one access point. That can be more comfortable for the patient than repeated separate punctures.
3. Flexibility for Different Targets
Lengths from a few centimeters up to 30 cm and gauges from 8G to 23G give clinicians options for superficial and deep targets alike.
4. Consistent Setup
Kits and trays package matched components together. Staff spend less time gathering parts and are less likely to grab mismatched sizes.
5. Choice of Reusable or Disposable Systems
Facilities can choose disposable all-in-one instruments or a reusable Magnum or EleVation driver with single-use needles and probes, depending on volume and reprocessing capacity.
6. Support for Patient Confidence
Waiting for a diagnosis is hard. Reliable devices that help clinicians get an adequate sample the first time can shorten that wait and spare patients a repeat procedure.
How to Choose the Right Biopsy & Aspiration Needles
Start with the sample type. If the physician needs tissue architecture, look at core biopsy instruments or the EleVation system. If cytology is the goal, Chiba fine needle aspiration needles are the usual choice. For marrow, choose Jamshidi or Illinois needles or a complete tray.
Next, consider gauge. A lower gauge number means a larger needle and usually a larger sample. Higher gauges are thinner. The ordering physician or department protocol typically sets the preferred gauge for each procedure.
Then match the length to the target depth and approach. Core devices here run from 6 cm to 30 cm, and Chiba needles from 6 cm to 20 cm. If you are using a coaxial introducer, the biopsy needle must be long enough to pass through it and reach the target, so check both lengths.
Think about the mechanism. Some operators prefer semi-automatic devices for the ability to check stylet position before firing. Others prefer automatic or dual-firing devices.
Finally, confirm system compatibility. Magnum needles need a Magnum instrument, and EleVation probes need an EleVation driver. TruGuide coaxial needles are listed as compatible with Max-Core, Mission, and Magnum. When in doubt, contact our team with the product details from your current stock.
Frequently Asked Questions
1. What is the difference between a core biopsy needle and a fine needle aspiration needle?
A core biopsy needle cuts and captures a small cylinder of tissue, which preserves its structure for the pathologist. A fine needle aspiration needle, such as a Chiba needle, is thinner and collects cells or fluid using suction. The physician chooses the approach based on the lesion and the diagnostic question.
2. What does a coaxial introducer do?
A coaxial introducer is a slightly larger needle placed first to create a path toward the target. The biopsy needle passes through it, so multiple samples can be collected without a new skin puncture each time. The introducer must be matched in gauge and length to the biopsy needle.
3. What is the difference between semi-automatic and automatic core biopsy devices?
With a semi-automatic device, such as BD Mission, the operator advances the inner stylet first and then fires the cutting cannula. An automatic device, such as Max-Core, fires both stages in sequence. Many clinicians choose based on the target and personal technique, within department protocol.
4. Are these needles reusable?
Most needles, instruments, and probes in this category are sterile and single-use. The BD Magnum instrument and the EleVation driver are reusable handpieces and must be reprocessed according to the manufacturer’s instructions. The needles and probes used with them are disposable.
5. What sizes of Chiba needles are available?
Chiba fine needle aspiration needles in this category come in 18G, 20G, 22G, and 23G. Lengths include 6, 9, 10, 15, and 20 cm, though not every length is offered in every gauge. They are sold 10 per case.
6. What comes in a Jamshidi bone marrow biopsy tray?
Trays gather supplies for a bone marrow procedure in sterile packaging. Options include trays with an original Jamshidi needle, trays with an Illinois needle, and standard trays with no needle included. Check the individual listing for the full contents and needle size.
7. Who should perform biopsy and aspiration procedures?
These procedures should be performed only by trained, credentialed clinicians under a physician order and according to facility protocol. This page is meant to help with product selection and purchasing, not as clinical instruction.
