Surgical biopsy device with automatic rotation of the probe for obtaining multiple samples.

摘要

"Surgical biopsy device with automatic rotation of the probe for obtaining multiple samples.According to the present invention is to provide a device for biopsy and methods for collecting at least one tissue sample from a surgical patient.The device includes a structure and a drilling element attached to the distal end of the elongated structure.The drilling element with a distal end, a proximal end and the light extends partially through the same.The drilling element is equipped with a state sharp on the distal end of the same for piercing tissue, and a proximal orifice while exposed to light.The device additionally includes an elongated cutter and an element of removal of tissue prepared coaxial and form deslizu00e1vel within the light of the drilling element to collect mass TISSPrepared inside the hole of the element (reset drilling and deposit the tissue mass proximal to the orifice to withdrawal.Finally, the device includes a mechanism for automatically and axially rotate the element of perforation after cutting the sample.So that multiple samples may be collected on the longitudinal geometric axis of the element of perforation without turning manually the element of drilling.
