Description

Pulse ablation electric connection assembly Technical Field The invention relates to the related technical field of medical instrument connectors and the like, in particular to a pulse ablation electric connection assembly. Background The pulse ablation operation is an effective medical means for treating arrhythmia diseases such as atrial fibrillation. The operation utilizes pulse equipment to deliver pulse high-voltage current to electrodes in a patient body, thereby completing ablation treatment of focus tissues. In this process, the electrical connection assembly of the connection device to the surgical handle plays a critical role. However, the existing pulse ablation electrical connection scheme has a number of problems: First, since high voltage pulses of several kilovolts are transmitted, the electrical connection line must have extremely high withstand voltage. The conventional technology generally adopts a rubber core and terminal structure, so that in order to meet the requirement of high voltage resistance, the creepage distance and the electric gap have to be remarkably increased, and the overall dimensions of the connector and the cable assembly are very thick. This not only increases the difficulty of the operation of the device, but also takes up valuable operating room space. Second, to compromise medical costs and hygienic safety, surgical attachment links often need to distinguish between reusable and disposable portions. The prior art often lacks systematic design, and is difficult to flexibly realize long-term fixed installation of equipment ends, repeated killing of middle sections and convenient discarding of handle ends. In addition, the prior art, such as CN120073362a, although referring to high voltage connectors, is still not structurally sound. On one hand, a complete connection link from equipment to a handle cannot be constructed by only a pair of connectors, on the other hand, the insulation treatment process of the existing connectors at the tail end welding line is complicated, and a plurality of layers of protection sleeves are usually required to be additionally sleeved on the welding point of each wire and the inner insulation sleeve of each wire. The structure not only increases the number of parts and assembly procedures and reduces the production efficiency, but also has large alignment and fixing difficulty of the multilayer sleeve, and the reliability is difficult to ensure under long-term use, so that the risk of high-voltage breakdown exists.
