hang knife is a magical knife! This knife was designed by Zhang Jianguo, a
doctor from China. Using this knife, he proposed a new method of endoscopic
resection, endoscopic submucosal resection (ESR): the endoscope does not have
a transparent cap, and there is no need to dive into the submucosa, but only need
to insert the Zhangknife into the submucosa and cut continuously the submucosal
tissue. The operational steps include: firstly by marking the lesion, followed by
submucosal injection, making an incision about 0.5-1.0 cm long outside the
lesion's right marking point and then the Zhangknife is along the incision was
inserted into the submucosa and the submucosa was cut from right to left and
proximal to distal. In this process, note that the zhangknife head is always axially
parallel to the gastrointestinal wall, so that it is possible to avoid damage to the
muscularis propria to avoid perforation. Themethods of using the Zhang knife are:
1) The endoscope does not dive into the submucosa, but from the macroscopic
and moderate distance to observe and judge whether the knife head is parallel
to the muscularis propria? If it is parallel, it will be cut; if it is not parallel, it will
be made parallel by knife head direction rotation, knife wire bending direction,
endoscope knobs and endoscope body adjustment; According to the situation in
the cutting process, adjust timely, the length of the knife wire and the distance
between the endoscope and the lesion for optimal cutting efficiency and safety.
3) Current mode uses continuous cutting current instead of intermittent stripping
current. Continuous cutting is used instead of intermittent dissection and carve.
