Description
技术领域technical field
本发明涉及一种手术电极用远端引流装置及手术电极器械，属于医疗手术器械。The invention relates to a remote drainage device for surgical electrodes and a surgical electrode device, belonging to medical surgical devices.
背景技术Background technique
目前，在外科手术中，采用电极进行凝血或切割是最为高效的止血方式。其原理是利用高频电流对组织产生热效应来实现组织变性凝固，如果电极末端温度过高，会产生较大的热辐射，导致周围健康组织非预期灼伤。此外，随着低温等离子技术的发展，电极需要在生理盐水等电介质环境下才能产生等离子体，实现预期功能。因此，带注液功能的手术电极的应用越来越广泛。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.
现有带注液功能的电极手术器械受其结构和加工尺寸限制，注液输出端口无法设置在电极头的末端，当电极头向上弯曲时，受重力作用制约，液体在弯转部位仅向下流动，无法直接到达电极头上端工作区域；为了实现降温冷却或创造等离子电解环境，通常需要在激发电极前事先注入大量的电解液(如生理盐水等)，完全浸没组织。此操作需要耗费大量电解液，影响手术视野，且不能完全实现电解液的循环流动，液体局部温升过快，临床效果欠佳。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, and cannot directly reach the working area on the upper end of the electrode tip; in order to achieve cooling or create a plasma electrolysis environment, it is usually necessary to inject a large amount of electrolyte solution (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, and the local temperature of the liquid rises too fast, resulting in poor clinical results.
