Abstract
A biopsy surgical appliance comprises a biopsy needle having a stylet (21) and a cannula (31), disposed coaxially along an axis (Y) and activated by a mechanical device with two slides (20, 30) which can slide longitudinally inside a shell (10, 50). The first slide (20) of the two slides (20, 30) has a "U" shape with tines (22a, 22b) oriented longitudinally and is moved longitudinally in a first operative environment, in which the central section (22c) of the "U" shape supports one component (21) of two components (21, 31) which constitute the biopsy needle (21, 31). The second slide (30) of the two slides (20, 30) has a head (32) which extends towards and beyond the axis (Y) without interfering with the first operative environment and is inserted freely between the tines (22a, 22b) of the first slide (20), and in which the head (32) supports the other component (31) of the two components (21, 31) which constitute the biopsy needs.
