Cases of blunt needle in Nexplanon® insertion device.

I have used both the Implanon (discontinued October 2010) and the new Nexplanon in practice since 2006. Only recently did I notice that during fitting one particular batch of Nexplanon (195129/312993) was slightly harder to both puncture the skin and then advance the needle. I do not routinely use a scalpel blade to facilitate fitting and neither do I anaesthetise along the track. I was able to...

A Force Feedback Teleoperated Needle Insertion Device for Percutaneous Procedures

A novel robotized tool for percutaneous interventions under CTscanner guidance is presented in this paper. This teleoperated compact robotic device can be used as an end-effector for an imageguided positioning robot. It is fully compatible with computed tomography constraints. In particular, it is able to manipulate needles that are longer than the overall height of its body. This novel device ...

PERCUTANEOUS TRANSTHORACIC BIOPSY USING TRU-CUT NEEDLE

Biopsies of thoracic lesions guidance. 22 of the 1 12 lesions were mediastinal and 83 were pleuroparenchymal. A large-bore 14-gauge Tru-cut needle was used in all patients. Adequate specimens for histologic examination were obtained in 98%. The overall accuracy was 91 % with 9% false negative and no false positive diagnoses. Despite the large size of the needle, the total number of complic...
