Jem’s shady needles a trusted name in bone marrow sampling takes biopsy technology to the next level with two disposable needle and aspiration options for over 40 years the gem cheney name has been synonymous with proven reliability and superior results from the original gem she needle to the advanced t-handle gem GT needle with crown tip and marrow acquisition cradle gem she D products deliver dependability and innovative features that make them a first choice in bone marrow biopsy needles and trays since its introduction the original gem GT bone marrow biopsy and aspiration needle has been a best-seller decade after decade it features a lightweight handle with a built-in comfort knob that allows clinicians to apply sufficient pressure without discomfort the razor-sharp bevel tip permits easy coring of the bone and the distal taper tip facilitates recovery of the bone marrow sample without altering its architecture here’s how it works introduce the gem GT bone marrow biopsy needle as you normally would with firm pressure and an alternating clockwise counterclockwise motion the razor sharp bevel tip enables the needle to quickly and easily penetrate the cortical bone once the cortical layer has been breached unscrew the cap and pull the stylet out of the handle slowly advance the needle with a slight clockwise counterclockwise motion until adequate marrow is obtained this can be tested by gently placing the stylet back into the needle to estimate the size of the sample since simple architecture can be damaged from excessive movement let’s watch that again slowly advance the needle using a slight clockwise counterclockwise motion until adequate marrow is obtained once an appropriate sample size is realized rotate the needle 360 degrees ten times to the left and ten times to the right using a quick motion and light downward pressure to allow the taper tip to help sever the specimen slowly remove the needle and specimen with the same clockwise counterclockwise motion after removing the needle place the probe guide on the distal end of the needle then using the Shepherd’s hook push the specimen out through the proximal end of the needle onto a specimens line now let’s take a look at the advanced technology of another option the t-handle gem Sheedy bone marrow biopsy needle with chrome tip and marrow acquisition cradle this remarkable biopsy needle and retention system requires less force promotes greater patient and user comfort and helps to ensure optimal specimen retention and superior specimen quality together this t-handle gem GT needle and marrow acquisition cradle is the only system specifically designed to obtain multiple samples during a single procedure without the need for painful redirection it’s all made possible by the advanced engineering of the gem cheney crown tip cannula trocar stylet and merrill acquisition cradle together these components optimize bone marrow biopsy procedures the unique design of the trocar tapered stylet point and the triple crown cannula tip creates an extremely sharp ultra effective cutting edge the result is superior cortical penetration and medullary advancements that require 25% less physical force to perform the biopsy procedure in addition unlike other marrow retention devices the gem Sheedy marrow acquisition cradle minimises specimen compression helping to maintain specimen integrity here’s how the needle and cradled work together the pinpoint stylet contained in the needle anchors securely on the cortical layer so there’s less chance of painful skating across the nerve Ridge periosteum the distinctive tip geometry of the needle allows it to effectively pass through the cortical bone introduced the t-handle Jamshid II bone marrow biopsy needle as you would normally with firm pressure and an alternating clockwise counterclockwise motion once the cortical layer has been breached the trocar stylet is rotated 90 degrees counterclockwise and withdrawn slowly advance the needle with a slight clockwise counterclockwise motion until adequate marrow is obtained the tapered distal tip of the crown cannula continues to advance through the medullary cavity the six surgically sharp cutting facets of the cannulas crown tip produce a clean controlled advancement with minimal trabecular disruption because sample architecture can be damaged with excessive clockwise counterclockwise movement it’s important to watch this again slowly advance the needle with a slight clockwise counterclockwise motion until adequate marrow is obtained with the needle in proper position the marrow acquisition cradle is then inserted into the crown cannula but only far enough for it to rest on top of the specimen the resulting exposed length of the marrow acquisition cradle that is protruding from the proximal end of the canula corresponds to the approximate length of the sample the Jamshid ii needle and cradle allow you to obtain sample lengths of up to four centimeters once the sample length has been identified the maro acquisition cradle is fully advanced into the crown cannula the maro acquisition cradle is rotated 360 degrees effectively separating the bone-marrow core notice that the maro acquisition cradle rotates not the needle the only turning that takes place is on the inside of the cannula there’s no need to twist or oscillate the needle in order to separate the specimen from the cavity so there’s less chance of irritating the sensitive periosteum there’s also a reduced chance of altering the architecture of the sample that’s because the bevel distal tip of the maro acquisition cradle doesn’t extend to the tip of the crown cannula where crushed artifact is most likely to occur after a single rotation of the maro acquisition cradle a non fragmented trephine is cut from the medullary cavity the marrow acquisition cradle is then withdrawn from the cannula the specimens treffen rests in the trial of the marrow acquisition cradle which securely holds the sample reducing the chance of it getting dislodged accidentally the sample is ejected from the cradle by advancing the support rod through the proximal end of the cradle ejecting the sample from the distal portion of the marrow acquisition cradle reduces the risk of dangerous needle sticks that are associated with normal specimen retrieval if an additional specimen is desired the procedure can be repeated using the same cortical passage and the same cannula that’s right there is no need to introduce another bone marrow biopsy needle in order to obtain additional samples simply advance the biopsy needle farther into the medullary cavity insert the marrow acquisition cradle rotate and withdrawal available separately or as a complete system the t-handle gem Sheedy bone marrow biopsy needle & merril acquisition cradle combined proven performance with innovative design to help you confidently perform procedures and obtain quality specimens virtually every time gem Sheedy needles advancing the science of bone marrow biopsy with two proven disposable needle and aspiration options from care fusion
