It further, further include the joint current with plug, joint current is at least electrically connected with two hemostasis components.Pass through one Platform radio frequency host connects more than two hemostasis components, and is combined into the arrangement mode of needs.Several hemostasis components pass through band Use (not needing connector to be fixed together) can be freely combined by having the joint current of plug to be connected with an interface on host, The size and shape of ablation areas is adjusted according to demand.
As an improvement being in series with selection switch between the joint current and each hemostasis component.Selection switch can appoint The quantity that meaning selection control hemostasis component is powered.The benefit of this design is that doctor can select to need to connect according to the actual situation Hemostasis component count, the hemostasis component that also can avoid not needing to use is conductive and influences operation.
As an improvement being provided with the connector for being cooperatively connected with other hemostasis components on the hemostasis component. Different states can be spliced between each hemostasis component by connector, using more convenient.
The connector is the mortise and tenon (mode without being limited thereto) for the connection that cooperates.
As a kind of further improvement, the hemostasis component is two, is provided with mortise on one of hemostasis component, The tenon being cooperatively connected with mortise is provided on another hemostasis component.Mortise and tenon are connector.The connection of mortise and tenon formula Simply, it consolidates, the ablation areas that 4 quick detachable and in one line electrodes generate can cope with majority of case.
It further include the shell of encapsulated electrode, the electrode extends outside shell as a kind of further improvement;The company Fitting is arranged on shell.Spool is stored using shell, facilitates arrangement, protects internal structure, while being convenient for multiple hemostasis components It is integrated.
As a kind of further improvement, the hemostasis component is two or more, all electricity when being applied in combination Pole is arranged in "-" type, and works pole and circuit pole is arranged alternately.
As a preference, the hemostasis component is two or more;When being applied in combination, all electrode arrangements are at two Row;The work pole and circuit pole are alternately arranged.Wider ablation areas can be formed.
As a preference, the hemostasis component is two of splayed arrangement;The work pole and circuit pole replace cloth It sets.The ablation areas of arc can be formed.
As a preference, the electrode is arc.
As a further preference, several hemostasis components are surrounded by a circle, and the bending direction of electrode is towards in enclosing, and institute There is electrode to be directed to same central point.The ablation areas of an approximate cup-shaped is formed, to adapt to certain particular procedure needs.
As a further preference, the hemostasis component is six, and pieces together one group two-by-two, the work pole and circuit Pole is alternately arranged.Two components first piece together one group, and then three groups of hemostasis components are circumferentially uniformly distributed.And the electrode is all It is arranged in such a way that work pole, circuit pole are arranged alternately, can preferably form a closed loop in this way.
As an improvement the electrode includes the electrode body of straight tube-like, described electrode body one end is closed point End.The shape of electrode is straight tube-like and has tip, so that electrode is convenient for going deep into tissue or is flat against the enterprising whereabouts blood of tissue, Suitable for various hemostasis.An overall co-ordination is connected into other hemostasis components using the connector on shell to use, It is powered more firm when melting.
As an improvement each electrode is provided with inlet and liquid return hole, and in each electrode It is provided with the cavity being connected to inlet and liquid return hole, inlet, cavity and liquid return hole constitute cooling medium circulation canal.At present The hemostasis electrode of hemostatic device there is no cooling function, lead to that tissue is dry and hard rapidly, carbonization, the phenomenon that " viscous knife " occur, at this time It needs that more times is spent to carry out clearing electrode.The RF energy density of electrode perimeter is much larger than the density of distant place, this is resulted in The tissue of electrode perimeter can be more easier to be dehydrated it is dry and hard, if the tissue premature dehydration of electrode perimeter is dry and hard, RF energy without Method is transferred to farther tissue and goes, then can not just stop blooding to the tissue of distant place, hemostasis range is greatly reduced.During each electrode is Sky has the cavity for cooling media flow;Cooling medium flows through the inside of electrode, takes away the heat of electrode;Therefore the temperature of electrode It spends not too high (being maintained at 25 DEG C or so), and the tissue of surrounding them will not be dry and hard too early, is not in " sticking phenomenon ", makes Obtaining RF energy can transfer out, and enable tissue heat production, dehydration, the hemostasis of distant place.After energization, RF energy can be within the organization Portion generates the ablation areas (or section is in ablation areas of quadrangle/trapezoidal) of substantially cuboid, after repeatedly melting, tissue Upper to form three-dimensional coagulation band, each side or the face for constituting coagulation band are relatively straight (straight flange, plane), are more conducive to cutting.With Solidifying belt edge is cut-off lines by the cutting tissue of lesion, cuts side and primary side is separated by coagulation band, avoid bleeding. Meanwhile the heat on electrode has been taken away by the flowing of cooling medium, so that electrode remains lower temperature, avoid viscous Knife phenomenon so that energy be enable to continue to export, and then generates biggish hemostasis range.Additionally, due to bipolar electrode (work pole With circuit pole) design, RF energy only transmits between the electrodes, and RF energy can expand in the vertical direction of electrode connecting line It dissipates, to form flat cuboid hemostasis (ablation) region (or section is in ablation areas of quadrangle/trapezoidal), stops blooding Regional rule is more convenient cutting operation, can greatly improve procedure efficiency.Therefore, this improves while solving existing haemostat Tool stops blooding region irregularly and the technical issues of easy " viscous knife ".This improvement can be not only used for surface hemostasis ablation, may be used also To be melted for the hemostasis of deep tissues.It can be used inside needle electrode insertion deep tissues, will form disappearing for cuboid Tabetisol domain;When flatting against tissue surface, relatively thin cuboid (or rectangle) ablation areas can be formed in tissue surface.It is long The length or width in cube shape hemostasis region and the ratio of thickness are usually not less than 2.

As shown in figures 10-13, usage mode embodiment 2 is two splits in one line of hemostasis component 1.It is noticeable It is that work pole 2 and reflux pole 3 need to be staggered.
There are four electrodes for two hemostasis components 1 splitting mode in one line on the same line, can form biggish disappear Tabetisol domain 22, therefore the coagulation band 27 repeatedly after ablation is also longer.
Figure 13 is the schematic diagram for flatting against tissue 21 and stopping blooding, and the mode flatted against is stopped blooding suitable for superficial large area.
As illustrated in figures 14-16, usage mode embodiment 3 is two hemostasis components 1 overlapping splits, it is also noted that Work pole 2 and reflux pole 3 need interleaved.All electrode arrangements are at two rows.
The splitting modes that two hemostasis components 1 are overlapped are square arrangement there are four electrode, can form biggish ablation areas 22, so the coagulation band 27 repeatedly after ablation is also wider.
This mode split is unsuitable for flatting against hemostasis.In addition being applied in combination for this mode does not need connector for two hemostasis Component 1 is combined into one, it is only necessary to the position of user's control two hemostasis components 1 by way of hand-held.
