The electric knife head bending part includes scale；
The electric knife shank is connected with the electric knife electric wire.
Further, the electric knife head bending part includes to be used for the proximal end sword of tensioned coagulation and cutting and for no-station pole canopy electricity
Solidifying and cutting distal end sword.
Further, the section of the electric knife head bending part is triangle, and the blade of Xiang Suoshu electric knife shank bending is described
Proximal end sword, adjacent another side are the distal end sword.
Further, the electric knife head shank includes cutting button, coagulation button and electric knife head jack.
Further, the electric knife head geometry can be electric knife tulwar head or electric knife sickle head.
Further, the geometry on the electric knife head is electric knife tulwar head, the electric knife head bending part and the electric knife
The axis in head rod portion -100 ° of angles at 45 °.

Further, the electric knife is made of stainless steel.
Further, the electric knife head bar portion cover insulation heat-shrink tube.
The utility model has the beneficial effects that can on an electric knife simultaneously realize hemostasis, cutting and by scale into
The effect of row distance judgement, and no-station pole canopy and tensioned cutting can be carried out, improve procedure efficiency and safety.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of measurable electric knife for endoscopic surgery of the utility model；
Fig. 2 is that a kind of part of the electric knife head bending part of measurable electric knife for endoscopic surgery of the utility model is put
Big schematic diagram.
In attached drawing, parts list represented by the reference numerals are as follows:
Electric knife head bending part 1, scale 2, proximal end sword 3, electric knife head bar portion 4, isolating shrinkable tube 5, electric knife shank 6, cutting is pressed
Button 7, coagulation button 8, electric knife electric wire 9, distal end sword 10.
Specific embodiment
In being described below, for illustration and not for limitation, propose such as project equipment structure, interface, technology it
The detail of class, to understand thoroughly the utility model.However, it will be clear to one skilled in the art that there is no these
The utility model also may be implemented in the other embodiments of detail.In other situations, omit to well-known device,
The detailed description of circuit and method, in case unnecessary details interferes the description of the utility model.
As depicted in figs. 1 and 2, the utility model discloses a kind of measurable electric knifes for endoscopic surgery, comprising: electricity
Knife electric wire 9, electric knife shank 6 and electric knife head, the electric knife head include electric knife head bar portion 4 and electric knife head bending part 1；
The electric knife head bending part 1 includes scale 2；
The electric knife shank 6 is connected with the electric knife electric wire 9.
High density high-frequency current heats the concentration of local tissue surface, make morphological element's rapid expanding of tissue burst and
Separate, procedures electrode is thinner thus, with tissue contact surface product it is smaller, more be conducive to cutting, cutting cut it is entirely different with machine cuts,
It does not need what external force applied.
Lower high frequency power, lower current densities heat bleeding and moist tissue, make liquid component (mainly moisture content)
Volatilization, tissue is dry, solidifies, sealing blood vessels, and the degree of not up to tissue explosion, therefore the power of blood coagulation wants small, Huo Zhezeng
The contact area of major operation electrode and hemostasis tissue and make current density decline (such as with electrode side clap touch), guarantee blood coagulation and
It does not cut.
In some illustrative embodiments, the electric knife head bending part 1 includes the proximal end for tensioned coagulation and cutting
Sword 3 and distal end sword 10 for no-station pole canopy coagulation and cutting.
