Description
Technical field
This utility model is related to high frequency electrosurgical equipment, especially a kind of high-frequency bipolar closing of cutting knife, this utility model
It is available for the tissue bundle of closing of cutting vascular, lymphatic vessel and suitable electrode jaw size in clinical departments application Rhizoma Atractylodis Macrocephalae.This apparatus warp
Special design can be used for the tissue in hysteroscope and open surgery and vascular closing of cutting.
Background technology
At present, one pole high frequency electric knife is cut to tissue and blood coagulation using circuit, and this circuit is by high frequency electric knife
High frequency generator and amplifier, patient, connecting wire and electrode composition.In most applications, using active wire and electrode
Electric current is exported operative site, patient is also served as an electrode of path by this kind of one pole cutting mode, easily non-to patient
Lesion portion applies excessive high-frequency energy, brings extra injury to patient.Bipolar high frequency electric knife generally adopts a pair of tongs
Or the two ends of scissors are as the two poles of the earth, as the effect pole in one pole high frequency electric knife and loop pole, the electric current of high frequency electric knife is defined
In a small amount of tissue in pliers direct effect region.Bipolar high frequency electric knife is mainly used to carry out blood coagulation to microscopic structure.
Utility model patent CN 102178559 discloses a kind of high-frequency bipolar closed cutting forceps, and it is provided simultaneously with blood coagulation and cuts
Cut the function of tissue.Binding clip ingredient has the first closure binding clip, the second closure binding clip and telescopic blade, and handle portion has
Two spanners, correspond to blood coagulation and the function of cutting tissue respectively.When promoting blood coagulation spanner, the first closure binding clip and second closes
Binding clip closes, and realizes bleeding tissue or the solidifying of blood vessel are closed.When promoting cutting spanner, the telescopic blade of binding clip is to reach
Dynamic, realize the cutting to tissue, notice that separate tissue is opened by cryoprobe sword by blade cutting action, and noenergy output.This kind of dress
The advantage put be pliers realize simultaneously blood coagulation and cutting tissue function, need not in operation process frequent switching simple function
Operating theater instruments.Need when being disadvantageous in that and tissue being cut first tissue to be carried out coagulating closing, then blade is released and cut
Cut, first promote blood coagulation spanner, promoting cutting spanner after the completion of tissue blood coagulation prompting, whole process is comparatively laborious, and knife
Piece cutting noenergy output, tissue no coagulates completely in the case of closing and promotes cutting spanner, will lead to bleeding.
Utility model patent CN 202397592 discloses a kind of disposable double-pole electric coagulation forceps, and it possesses coagulation function.Pincers
Head ingredient has active clamp and fixing clamp, and handle ingredient has flexible handle and fixed handle, and working mechanism is logical
Cross thumb and swing described flexible handle, pushing drawing rod is controlling the folding of binding clip.The advantage of this kind of device is that structure is simple, becomes
This is advantageous.It is disadvantageous in that only coagulation function, no cutting function.While fixing, activity, controlled opens binding clip
Angle is less, and handle no reset function, and long-time operation thumb is easily tired.

Specific embodiment
The present embodiment provides a kind of bipolar coagulation electric knife, and as depicted in figs. 1 and 2, it includes：
Cutter head assembly 10, pull bar 21, outer tube 22 and Handleset.
Described cutter head assembly includes acting on pole cutter head 101, loop pole cutter head 102, loop pole cutter head insulating part 103, centre
Insulating part 104, fixing axle 106, jackshaft 105 and pull rod shaft 107.
Described Handleset includes handle 25, runner 30, outer pipe clamp head 23, draw bar chuck 24, spanner 26, back-moving spring 27
And twin-core electrode wires 28.
Described pull bar 21 is arranged inside described outer tube 22, and described outer tube 22 is fixing with described runner 30, and pull bar 21 can be lived
Dynamic, pull bar 21 and outer tube 22 outer surface all have insulating barrier, prevent both from climbing electricity in a high voltage state.
Loop pole cutter head 102 is fixed on outer tube 22 by fixing axle 106, and loop pole cutter head 102 can rotate around fixing axle 106.
Jackshaft 105 interconnection function pole cutter head 101, loop pole cutter head 102 and Intermediate insulator 104, jackshaft 105 is ceramic material,
So can achieve the isolated insulation of effect pole cutter head 101 and loop pole cutter head 102.Pull rod shaft 107 interconnection function pole cutter head 101 with
Pull bar 21.When pull bar 21 occurs relative displacement with outer tube 22, effect pole cutter head 101 and loop pole cutter head 102 are with relative displacement
Change is opened and closure.Pull bar 21 and outer tube 22 outer surface all do insulation processing and prevent from climbing electricity generation.
Runner 30 is embedded in handle 25 and can be fixing with outer tube 22 around the 360 ° of rotations of handle 25 head, runner 30, i.e. runner
During 30 rotation, outer tube 22 and pull bar 21 also and then rotate.Outer pipe clamp head 23 and draw bar chuck 24 respectively elastic clamping outer tube 22 with draw
Bar 21 is fixed in handle 25.Outer pipe clamp head 23 is connected two cores of twin-core electrode wires 28, such high frequency respectively with draw bar chuck 24
Energy passes through outer pipe clamp head 23 to be transmitted to loop pole cutter head 102 and effect pole cutter head 101 with draw bar chuck 24.
The bipolar coagulation electric knife of the present embodiment is provided simultaneously with coagulation and cutting function of organization, and implementation is by trampling
Different high-frequency energies are exported about foot-operated.
The afterbody of pull bar 21 is embedded in spanner 26, and spanner fulcrum 260 is located above pull bar 21.When spanner 26 props up around spanner
During point 260 swing, pull bar 21 also moves forward and backward simultaneously, because outer tube 22 is fixed in runner 30 so that the position of outer tube 22
Opposite handle 25 is motionless, and when pull bar 21 swings with spanner 26 and moves forward and backward, pull bar 21 produces relative displacement with outer tube 22,
Thus the folding of control action pole cutter head 101 and loop pole cutter head 102.
Described back-moving spring 27 one end is fixed on described handle 25, and the other end is contacted with spanner 26.When spanner 26 backward
During swing, effect pole cutter head 101 is closed with loop pole cutter head 102, and back-moving spring 27 is in confined state simultaneously, unclamps spanner
After 26, back-moving spring 27 promotes spanner 26 to travel forward, thus holding effect pole cutter head 101 is in often with loop pole cutter head 102
Open state.
Fluting in the middle of loop pole cutter head 102, loop pole cutter head insulating part 103 is embedded in inside groove.When effect pole cutter head 101 with
During loop pole cutter head 102 closure, because there being the insulating effect of loop pole cutter head insulating part 103, the two poles of the earth persistently have energy to export, until
Tissue coagulates to close or cut and completes.
As shown in figure 5, described effect pole cutter head 101 and loop pole cutter head 102 all carry radian, both radians are consistent, maximum
Bending point is 2.0～3.0mm with the distance of cutter head center line.
It should be pointed out that for the person of ordinary skill of the art, before conceiving without departing from this utility model
Put, some deformation can also be made and improve, these broadly fall into protection domain of the present utility model.Therefore, this utility model
The protection domain of patent should be defined by claims.
