Further, referring to the portion of pinching includes several domes being arranged on handle of a knife, and several domes are arranged in a square.

Further, it is provided with a Lighting Division for being in annular towards one end of cutter hub on handle of a knife.

Further, the radian of arc sections is 45 degree.

Further, handle of a knife is provided with a finger grip.

Further, illuminating lamp is cold light lamp.

The beneficial effects of the utility model are：

1st, the tail end of the knife bar of electric knife is connected by coagulation line with high impulse electric coagulation machine, is stopped while cutting using coagulation Blood, reduce intraoperative hemorrhage.

2nd, a regulation button is provided with handle of a knife, for adjusting size of current, prevents high current scalded tissue in cutting.

3rd, by groove and the mutual fastening of lug boss, knife bar is positioned；Prevent after a long time use, knife bar There is the phenomenon loosened, influence cutting accuracy.

4th, seamlessly transit between blade and blade, cut by blade, ensure that cutting ground quickly with steadily, and by The hemostasis electric current smaller therefore required in the contact area of blade and tissue is smaller, lighter to tissue scald, can contract Short wound healing time.

5th, the front end of blade and blade is equipped with an outwardly arc sections, and position to be cut is pointed to point of a knife, then Steadily cut along arc sections, and the spacing on blade between any one place's sword side and blade is equal, ensure that flap cutting is thick Thin is uniform.

6th, the both sides of handle of a knife are symmetrically arranged with finger and pinch portion, and when being cut, the thumb and forefinger of doctor can be pinched to be pinched to finger Portion, for increasing frictional force between finger and handle of a knife, it is easy to the control to electric knife.

7th, illuminated by Lighting Division, irradiate surgical wound surface tissue, operated to make doctor get a clear view, beneficial to doctor.

8th, a finger grip is provided with handle of a knife, in cutting, prevents hand from skidding.
