Far-end drainage device for operation electrode and operation electrode instrument

Abstract

The invention discloses a far-end drainage device for an operation electrode and an operation electrode instrument. The operation electrode instrument is internally provided with an infusion channel.The far-end drainage device for the operation electrode comprises a guide pipe, a fixing sleeve, and a drainage pipe. The guide pipe is used for installing the electrode part of the operation electrode instrument, and the far-end part of the guide pipe is used for fixedly connecting with an electrode tip of the electrode part. The fixing sleeve sleeves the periphery of the guide pipe. The near-endpart of the drainage pipe is fixedly connected to the fixing sleeve. The far-end part of the drainage pipe is positioned at the periphery of the guide pipe. The far-end drainage device for the operation electrode is capable of enabling the outlet for flowing out liquid to be completely consistent with the electrode excitation area of the electrode tip, and has the characteristics of more accuratetarget positioning, convenient assembly, simple technology and good universality. The size of the drainage device can be regulated according to the size of the electrode tip and the guide pipe, and is not limited by the position of the liquid outlet. The processing cost is remarkably reduced, and the device is suitable for any types of the operation electrode instruments.

Description

technical field [0001] The invention relates to a remote drainage device for surgical electrodes and a surgical electrode device, belonging to medical surgical devices. Background technique [0002] At present, in surgical operations, coagulation or cutting with electrodes is the most efficient way to stop bleeding. The principle is to use high-frequency current to generate thermal effect on the tissue to achieve tissue denaturation and coagulation. If the temperature of the electrode end is too high, large heat radiation will be generated, resulting in unexpected burns of surrounding healthy tissues. In addition, with the development of low-temperature plasma technology, the electrode needs to be in a dielectric environment such as physiological saline to generate plasma and achieve the expected function. Therefore, the application of surgical electrodes with liquid injection function is becoming more and more extensive. [0003] The existing electrode surgical instrument...

AI Technical Summary

Problems solved by technology

[0003] The existing electrode surgical instrument with liquid injection function is limited by its structure and processing size. The liquid injection output port cannot be set at the end of the electrode head. Flow, unable to directly reach the working area on the upper end of the electrode head; in order to achieve cooling or create a plasma electrolysis environment, it is usually necessary to inject a large amount of electrolyte (such as physiological saline, etc.) before exciting the electrode to completely immerse the tissue

This operation requires a large amount of electrolyte, which affects the surgical field of view, and the circulation of the electrolyte cannot be fully realized. The local temperature rise of the liquid is too fast, and the clinical effect is not good.
