a sampling unit, configured for acquiring a tissue sample;
a control unit, configured for controlling a working state of the sampling unit and comprising a first adjustment assembly, wherein the first adjustment assembly comprises a first adjustment knob and an actuating string, and the actuating string is rigid; and
a connecting tube, assembled to the control unit and having at least one end running through the control unit, and one end of the connecting tube being fixedly assembled to the sampling unit,
wherein one end of the actuating string is fixed to the first adjustment knob and an other end of the actuating string is fixed to the sampling unit; and the sampling unit is controllable to be opened or closed by controlling the first adjustment knob;
the sampling unit comprises a sampling sheath, a supporting portion and a heating member, wherein one end of the sampling sheath inserts into the connecting tube and connected to the connecting tube, and an other end of the sampling sheath is connected to the support portion; the support portion is deformable upon an external force, and the heating member is mounted around the sampling sheath; and
the one end of the actuating string is fixed to the first adjustment knob and the other end of the actuating string is fixed to the heating member; the actuating string is controllable to move by controlling the first adjustment knob, whereby the heating member is controlled to be opened or closed, which in turn drives the support portion to be opened or closed.
