What is the method of using the coaxial positioning pin?

Under the image guidance, puncture the coaxial positioning needle to the edge of the lesion, adjust the angle, take out the needle core, indwell the needle sleeve, insert the wound biopsy gun/needle into the needle sleeve, and take out the biopsy gun/needle after firing. Put back the core of the coaxial positioning needle, take out the tissue sample in the biopsy gun/needle, and continue to wind up, ready for the next sampling. Fine-tune the angle of the coaxial positioning needle, take out the needle core, insert the biopsy gun/needle again to take a sample, repeat the first two steps until you have enough samples, if the lesion is less than 1cm, you can also use the coaxial positioning needle to get 1cm sample. GCO coaxial positioning needle can be used with TZ, Evolution and Speed-Cut soft tissue biopsy needles/guns. GCO can be integrated with the biopsy needle/gun with a plug-in connection port. Prevent the biopsy needle/gun from rotating after being inserted into the coaxial positioning needle; exert the overall function. The outer diameter of the biopsy needle is only 1G larger than that of the biopsy needle, which reduces the risk. The needle body is 5cm shorter than the biopsy needle of the same model. Because the needle handle has 3cm, and the biopsy needle is retracted by 2cm after it is wound, it is completely matched with the biopsy needle of the same model. Injury to the tissues, it can also prevent the transfer of the needle track. The front end of the needle sheath is polished, and the needle core has a groove, which enhances the visibility under ultrasound.
