Abstract
The invention discloses a kind of methods for increasing surgical closure bandwidth, and binding clip includes top electrode, lower electrode；The cross section of the top electrode and lower electrode is curve, and top electrode and lower the electrode shape of curve in closure cooperate.It is of the invention in the case where claw beam diameter is constant by setting mutually matched curve for the cross section of top electrode and lower electrode, to dramatically increase the width of binding clip clamping.After upper/lower electrode clamps tissue or blood vessel, electric current passes through the electrode slice of superior pole piece -- tissue or blood vessel -- by conducting wire, and lower electrode returns to forming circuit；Insulation gap is coated on curved surface, to guarantee the gap for forming needs during occlusion.
Description
Technical field
The present invention relates to a kind of methods for increasing surgical closure bandwidth.
Background technique
The range that Minimally Invasive Surgery is applied at present is more and more wider, and many case hospitals all start to replace passing using Minimally Invasive Surgery
The Surgical Operation of system, the medical instrument size of mating Minimally Invasive Surgery also become smaller and smaller, lead to the binding clip retained part of instrument
It is more and more narrow, and for being closed big blood vessel etc. with being closed the positively related medical instrument of bandwidth, narrow binding clip zonula occludens is to blood
The closure effect of pipe becomes very fragile, is easy to cause the Operation of bleeding and secondary bleeding.
Summary of the invention
For solution, binding clip retained part is more and more narrow in the prior art, closure effect of the narrow binding clip zonula occludens to blood vessel
Become very fragile disadvantage, the width of binding clip clamping is dramatically increased in the case where claw beam diameter is constant.
A method of increasing surgical closure bandwidth, which is characterized in that its binding clip includes top electrode, lower electrode；It is described
The cross section of top electrode and lower electrode is curve, and top electrode and lower the electrode shape of curve in closure cooperate.
Further, the top electrode includes upper electrode holder and electrode slice, and the upper electrode holder and electrode slice are using injection molding
Encapsulated mode connects.
Further, power supply keeps insulation by conducting wire connection electrode piece between the upper electrode holder and electrode slice.
Further, the lower electrode is processed using bulk metal, can also be used the top electrode fission mode, and with electricity
Source connection forming circuit.
Further, the cross section of top electrode and lower electrode is the combination of wave, camber line or wave and camber line.
Further, the consistent insulation gap point of several height is coated in the surface explosion of top electrode or lower electrode.It is excellent
Choosing, the spaced points are ceramics.
It is of the invention in the case where claw beam diameter is constant by setting mutual for the cross section of top electrode and lower electrode
The curve of cooperation, to dramatically increase the width of binding clip clamping.After upper/lower electrode clamps tissue or blood vessel, electric current passes through conducting wire
By the electrode slice of superior pole piece, --- ----tissue or blood vessel --- ----lower electrode return to forming circuit；It is coated on curved surface absolutely
It is intermarginal every to guarantee the gap for forming needs during occlusion.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is structural schematic diagram of the invention；

Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment
A method of increasing surgical closure bandwidth, binding clip includes top electrode 10, lower electrode 20；Top electrode 10 is under
The cross section of electrode 20 is waveform, and the heaving of the sea in closure of top electrode 10 and lower electrode 20 cooperates.Top electrode
Comprising upper electrode holder and electrode slice, upper electrode holder connects in such a way that injection molding is encapsulated with electrode slice, and power supply passes through conducting wire and connects

Surface explosion is coated with the consistent ceramic space point 30 of several height.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
