A review of the device history records was conducted and no similar concerns were found.Four devices were returned for review.The devices were examined and test fired with no firing issues noted.However, all of the devices exhibited pincer damage which would prevent the devices from taking samples successfully.Pincer damage can occur as a result of hitting hard or calcified tissue, handling of the device during use, such as tilting the needle to extract the sample onto a slide, or during reinsertion into a coaxial needle.These possible root causes occur during use of the device.Pincer damage may also occur if the pincer does not properly enter the device inner coring cannula slot (window).Therefore, argon r&d has decided to review the issue to determine if any changes can be made to improve the overall performance of the device.During manufacture of the devices, there are several inspections to ensure the proper shape of the pincer and to ensure the overall proper function of the device.

The pincer does not go into the window.Lays outside, or bent outwards, and no biopsies taken.Happens with and without use of coaxial needles.Biopsy ¿ muscle ¿ upper leg.After the doctor fired biopince into the muscle, it was difficult to remove.This have led to complications (i.E.Bleedings & pain).In at least one occasion, biopince had to be cut out.
