NEEDLE FOR CUTTING biopsy focal lesions abdominal and retroperitoneal ultrasound scan UNDER CONTROL

摘要

The invention relates to medicine, namely to surgical instruments, in particular, used for cutting biopsy focal lesions in the abdominal surgery.; The technical result of the proposed device is to change the parameters of the needle, the improvement of its visualization, which enhances the safety of interventions by reducing the risk of complications.; Our proposed puncture needle has the following changes:; 1) reduction of the length of the stylet needle chute 13 mm to 8 mm is not significantly reflected on the intake volume of material, but increases the stiffness of the needle at the specified location, preventing it from bending and deflection retrace axis. The latter prevents the stylet from the chute cutting the resulting material of the outer cutting edge of the needle cylinder;; 2) improved needle visualization by increasing its luminescence brightness is achieved by applying high-energy laser on the distal stylet separated at a distance of 15 mm arranged circularly 5 laser marks.; Thus, the proposed needle provides high directivity intervention to reduce its trauma and reduce the risk of complications.
