Patent technology of biological electrical impedance auto-measurement (BEIM) makes tissues dry and hard without carbonization. While curing hemorrhoid, BEIM pincers generates heat rapidly to vaporize water of hemorrhoid tissues instantly. The electronical impedance of hemorrhoid tissues becomes larger and larger. While electrical impedance of hemorrhoid tissues matches with output impedance of the device, the tissues become dry and hard without carbonization, and at the same time the device sounds the alarm automatically. 

It settles the technological difficulty of time setting by person presently and medical difficulty of massive haemorrhage after operation by other treatment methods. Used for making the base of the hemorrhoid dry and hard so as to seal off the base, no blood can flow out. It possess patent technology of biological electrical impedance auto-measurement (BEIM), which can auto-measure the electrical impedance of hemorrhoid tissues, according to which the pincers auto-generate the right heat so as to make tissues dry and hard of high quality: No stitch & no bleeding.
