The main improvement point of the present invention is that the structure of the working pole is designed as a sheet-like end face and a bent portion, and the end face is set as an excitation sheet by opening a hole (that is, the end face left after the hole is opened. ), and further set the outer excitation sheet into a structure with a gradually narrowing width from the bottom of the end surface to the side, and the width of the bent portion is larger than the width of the bottom of the excitation sheet (that is, the width of the bent portion D3 >Shot plate bottom D2>Stimulus plate side D1). Compared with the existing technology, the sheet electrode will be disconnected from the middle or even the whole. This structural design makes the top of the external excitation sheet easier to melt by the energy of the plasma, and the first melted part becomes The top of the external excitation sheet will not be disconnected from the middle or bottom and fall into the human body, so as to avoid the large piece of working electrode material falling into the human body after being melted during the operation, which is difficult to take out. In addition, after repeated tests, during the melting process, the working electrode will still generate plasma and can continue to work.

This structure can also generate plasma in the end face of the sheet, which is more conducive to cutting.
5.进一步的，本发明将内激发片呈“一”字形设置，其上、下两端连接在外激发片的底部与顶部之间，且内激发片上端与外激发片连接处的外侧设有缺口。这种结构使得外激发片顶部的宽度减小，相比于上述方案，使之更容易熔化，防止片状电极从其中间断开甚至整体断开而掉入人体，一般手术完成后，熔化的部分最多也只有激发片的顶部及附近一小部分，完全不影响手术进行，进一步减小了手术对人体造成的危害，安全性更高；即便更长时间的使用也不会从中间甚至整体掉落，安全性更高，效果更好，寿命更长。同时，这种结构使外激发片顶部产生更强的等离子体，切割更锋利，效果更好。5. Further, in the present invention, the inner excitation sheet is arranged in the shape of a "one", and its upper and lower ends are connected between the bottom and the top of the outer excitation sheet, and the outer side of the connection between the upper end of the inner excitation sheet and the outer excitation sheet is provided with. gap. This structure reduces the width of the top of the external excitation sheet, which makes it easier to melt compared to the above-mentioned solution, preventing the sheet electrode from being disconnected from the middle or even the whole of it and falling into the human body. Generally, after the operation is completed, the melted part At most, there is only a small part of the top and the vicinity of the excitation film, which does not affect the operation at all, further reduces the harm caused by the operation to the human body, and is safer; even if it is used for a longer time, it will not fall from the middle or even as a whole. , higher safety, better effect and longer life. At the same time, this structure makes the top of the outer excitation sheet generate stronger plasma, and the cutting is sharper and the effect is better.

8.进一步的，同上，本发明在孔的内侧设有倒圆角，可产生相对更均匀的等离子体，切割效果更好。8. Further, as above, the present invention is provided with rounded corners on the inner side of the hole, which can generate relatively more uniform plasma and has better cutting effect.
9.本发明进一步的方案中，端面部的顶部与回路极的距离小于端面的底部与回路极的距离，使端面部的顶部能够更早产生等离子体，也有利于端面部的顶部产生更强的等离子体，使得端面部的顶部更容易熔化，可防止片状电极从其中间断开甚至整体断开而掉入人体，进一步减小了手术对人体造成的危害，安全性更高。9. In a further scheme of the present invention, the distance between the top of the end face and the return pole is smaller than the distance between the bottom of the end face and the return pole, so that the top of the end face can generate plasma earlier, and it is also beneficial for the top of the end face to generate stronger plasma. The plasma can make the top of the end face more easily melted, which can prevent the sheet electrode from being disconnected from the middle or even disconnected as a whole and falling into the human body, further reducing the harm caused by the operation to the human body, and the safety is higher.

11.进一步的，本发明将端面部侧部的激发片宽度设置为大于所述端面部顶部的激发片宽度，更有利于端面部的顶部熔化，可防止片状电极从其中间断开甚至整体断开而掉入人体，进一步减小了手术对人体造成的危害，安全性更高。11. Further, the present invention sets the width of the excitation sheet on the side of the end face to be larger than the width of the excitation sheet at the top of the end face, which is more conducive to melting of the top of the end face, and can prevent the sheet electrode from being disconnected from the middle or even the whole.
