FIELD: medicine. ^ SUBSTANCE: invention refers to medicine, surgeries and can be used as an endoscopic tool ensuring sequential tissue dissection and transection. A universal dissector represents an endoscopic tool. Said endoscopic tool accommodates a working component comprising two straight branches, a connecting tube and a handle. The branches are perpendicular to the connecting tube axis and have thinned and rounded distal ends. Their internal surfaces are cutting, while their external surfaces are semi-oval and designed for dissection of anatomic structures. The distal branch is fixed, while the proximal branch travels along the connecting tube axis. Application of the given tool makes it possible for both tissue dissection and transection performed sequentially perpendicularly to the action axis. ^ EFFECT: unlike endoscopic scissors, the present tool allows transecting strictly the tissue region only been under bipolar coagulation, thus eliminating probability that transection might precede coagulation. ^ 2 dwg |
