Description
Technical field
The utility model relates to medicine electrosurgical unit technical fields, and in particular to a kind of single rod bipolar high frequency electric knife.
Background technique
Electric knife is a kind of electrosurgical unit for replacing mechanical operation knife to carry out tissue cutting, it passes through active electrode point
The high-frequency high-voltage current that end generates heats tissue when contacting with human body, realizes separation and solidification to injected organism tissue, from
And the purpose of cutting and hemostasis is played, compared with tradition machinery performs the operation knife, cutting speed is fast, and haemostatic effect is good, adapts to operation
Range is wide, safe ready, is able to satisfy cutting, hemostasis, reduces the surgical operations basic demands such as damage.Clinically use high frequency hand
Art knife can substantially shorten operating time, reduce the blood loss of patient, reduce complication rate, save Operation Fee etc..
Electric knife is there are two types of main operating mode: monopole and bipolar.In monopolar mode, with a complete circuit come
Cutting and solidified structure, the circuit are made of radio-frequency generator, patient's pole plate, in succession conducting wire and the electrode in electric knife.?
In most of application, electric current passes through patient by active wires and electrode, then returns to high-frequency electrical by patient's pole plate and its conducting wire
The generator of knife；But there is certain risk of burning to human body using monopole electric knife.In double pole mode, bipolar coagulation
To provide high-frequency electrical energy to body tissue by two tips of bipolar forceps, make the blood vessel between bipolar forceps both ends be dehydrated and
Solidification, achievees the purpose that hemostasis.Its sphere of action is only limited between tweezers both ends, on the degree of injury of body tissue and influence
Range is much smaller more than unipolar fashion, and still, the bipolar electric knife of tweezers is point contact processing to tissue progress.Tweezers behaviour
The finger manipulation required precision made to doctor is high, and colleague also needs trick cooperation control current switch, these considerable drains doctor
Energy, so that the inconvenient operation safety that possibly even influences leads to notch and seal bad to cause postoperative complication.
Therefore in existing bipolar high frequency electric knife structure, the structure of bipolar high frequency electric knife how is further improved, reduces behaviour
Make hidden danger present in difficulty and operation, the efficiency and safety for improving operation are researched and developed in current bipolar high frequency electric knife structure
One of important subject of personnel.

Further, the angle α of the special-shaped cutter head and knife bar is set as 90 °~270 ° by the difference of operative site.
Further, the handle is equipped with the display lamp for showing power supply on state.
Further, the insulation sleeve being isolated for reinforced insulation is equipped between insulation coating and the electrode casing of the knife bar
Cylinder.
Single rod bipolar high frequency electric knife described in the utility model, by cutter hub, to form distance solid for insulation set electrode layer
Fixed dipolar configuration, doctor only needs single hand grip electric knife in surgical procedure, easily controls electricity by the control switch on handle
Source, this greatly reduces operation difficulty, improves procedure efficiency, and because the fixed width for making the edge of a knife in art of bipolar distance keeps equal
It is even, it reduces because of notch and seals the bad probability for causing postoperative complications；By being arranged in cutter hub for cooperating tracheae defeated
The function of channel extension electric knife of body or conduit substance of supplying gas improves procedure efficiency.
