Problems solved by technology

However, atrial septal puncture is still in the two-dimensional mode combined with X-ray imaging, and it has not been widely used in the field of "electrolocalization three-dimensional system" surgery, and it cannot achieve the characteristics of extremely low radiation, precise positioning and navigation.
Therefore, in the prior art, there is no electro-localization system combined with a puncture system guided by ECG signals to achieve precise puncture

Abstract

The invention relates to a puncture needle assembly and a puncture system. The puncture needle assembly comprises a needle seat and a needle body, the needle seat is provided with an axially through channel, at least one part of the side wall of the channel is configured to be an electric conductor, and the near end of the needle body extends in the channel and is electrically connected with the electric conductor. The puncture system further comprises a dilator, the dilator comprises a dilation catheter and an elastic conductive assembly selectively arranged on the dilation catheter, and whenthe far end of the needle body is hidden in the dilation catheter, the far end of the needle body is directly and electrically communicated with external blood through the elastic conductive assembly. The puncture needle assembly and the puncture system have the advantages of being safe and convenient to use and high in reliability.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture needle assembly and a puncture system. Background technique [0002] Cardiovascular disease is a serious threat to human health, and it has the characteristics of high prevalence, disability and high mortality. Interventional therapy is a relatively effective treatment method for cardiovascular diseases. When performing interventional therapy such as atrial fibrillation and atrial flutter, puncture is often required so that the interventional therapy device can pass through the interatrial septum and reach the lesion site. [0003] The dilator and the puncture needle are important parts of atrial septal puncture. The puncture needle uses the puncture ability of the distal stainless steel needle tube. When the catheter sheath and the dilator are assembled, the dilator and the catheter sheath pass through the atrial septum. The dilator On the basis of the pu...
