Jorgensen Labs J0116S Bone Marrow Biopsy Needle 13G x 4" Double-Side Diamond Tip

The JorVet J0116S needle features a precision-ground double diamond tip that cuts smoothly through dense cortical bone with minimal axial pressure, reducing patient trauma and operator exertion. Engineered specifically for veterinary oncology and hematology diagnostics, the razor-sharp stylet point prevents skidding on slippery periosteal surfaces upon initial insertion. Technicians and clinicians can achieve clean, controlled penetration into the medullary cavity without splintering the surrounding bone matrix. The balanced cutting geometry maintains structural sharpness throughout the procedure to ensure a swift, decisive tap. This efficient cutting action significantly shortens procedure times and lowers anesthesia risk for critical patients.

The 13-gauge thickness and 4-inch length are ideally proportioned for aspirating and harvesting bone marrow cores from medium-to-large canine breeds and large animal patients. Its 4-inch shaft length provides ample reach to access the trochanteric fossa of the femur, the humerus, or the iliac crest, even in deeply muscled or overweight animals. Veterinary oncologists frequently rely on this 13G dimension to obtain generous tissue volumes needed for complete staging of lymphoma, leukemia, or unexplained cytopenias. The sturdy shaft gauge resists bending or flexing when driving through thick cortical bone in athletic or mature patients. It serves as a core, highly versatile biopsy instrument for general referral hospitals and specialty oncology centers.

Equipped with an internal core sampler and extraction cannula, this needle cleanly severs and retains an intact bone marrow core without crushing the delicate cellular architecture. The specialized interior geometry prevents sample compaction or fragmentation during retrieval, yielding high-quality histologic specimens for pathologic evaluation. Veterinary pathologists receive preserved marrow architecture, allowing for accurate assessment of cellularity, megakaryocyte counts, and metastatic disease detection. Eliminating sample loss during withdrawal reduces the frustration of non-diagnostic draws and avoids painful repeat procedures for the animal. This superior sample retention directly improves diagnostic confidence and speed for complex hematologic cases.

Designed with a wide, ergonomic T-handle, the needle gives the clinician maximum palm comfort and leverage to apply controlled rotational force during cortical penetration. An integrated twist-lock mechanism secures the inner stylet firmly inside the outer cannula, preventing retro-displacement or slippage while advancing through bone. The textured surface ensures a non-slip grip even when operating in wet surgical environments or wearing fluid-covered gloves. Precise tactile feedback allows the surgeon to feel the distinct drop in resistance as the needle transitions from dense cortex into the spongy medullary cavity. These ergonomic safety controls protect the clinician from hand fatigue while ensuring steady, controlled depth advancement.

Each JorVet J0116S bone marrow needle is individually packaged in a sterile, tamper-evident peel pouch, ready for immediate use in sterile oncology and emergency suites. Manufactured to strict medical-device quality standards, the disposable single-use design eliminates the risk of cross-contamination between oncology patients. Eliminating the need for post-procedure cleaning, sharpening, and re-sterilization saves valuable technical staff time in high-volume specialty hospitals. The clear labeling on each sterile pack allows for rapid inventory identification and audit tracking in surgical prep areas. This sterile, ready-to-use packaging ensures seamless compliance with clinical hygiene standards and workflow requirements.
