摘要：
Method separates implanted object, such as pacemaker leads, from the tissue of these data collections, in the vascular system of patient. Specifically, which includes handle, elongated inner sheath and annular blade that from the distal end of sheath in driving handle. The circular cutter blade is configured to engage and cut the tissue around implantation conducting wire, and it is that operation device is converted into length along conducting wire that this group, which is woven in coring mode, to make lead and any tissue remain attached to lead, into the elongated shaft of the device. The blade that there is the surgical device cam drum roller handle assemblies that transmitting rotating blade and individual cam mechanism tip oversheath component to transmit each other and extend and be retracted. This barrel of camcylinder and cam mechanism cooperation, so as to be rotated in a first direction the blade and thereby and be withdrawn in oversheath, due to first starting handle and in a second direction rotation expansion and retract oversheath in, due to second start handle. Inner sheath and oversheath constitute laser-cut hypotube, thus allow surgical device, especially jacket assembly, and the vascular system of small size is used for lesser profile.
