The invention relates to an
endoscopic submucosal dissection instrument with a swallow-
tail form
tool bit. The
endoscopic submucosal dissection instrument comprises the openable swallow-
tail form toolbit, a transmission wire, a fixed
handle, a slidable
handle, a rotatable
handle and an electric connecting device, the rotatable handle drives the swallow-
tail form
tool bit to rotate, the front endof the transmission wire extends out of the fixed handle and is connected with the swallow-tail form
tool bit, the rotatable handle and the slidable handle are mounted on the fixed handle, the slidable handle is fixedly connected with the transmission wire, so that opening and closing of the swallow-tail form tool bit are controlled by the slidable handle, the rotatable handle is connected with the transmission wire through a vertical transmission structure, a
cutting edge of the swallow-tail form tool bit is positioned at the outer side edge of a blade, and the swallow-tail form tool bit is electrically connected with the electric connecting device through the transmission wire. When the swallow-tail form tool bit is closed, an opening can be formed in a
mucous membrane, two sides can besimultaneously
cut open by the
cutting edge after the swallow-tail form tool bit is opened, the electric connecting device is connected with a power supply,
cutting can be accelerated, blood coagulation effects are achieved, and a
dissection view is clearer.
