Combined ablation and puncture apparatus

Abstract

The invention relates to the field of ablation treatment apparatuses, and specifically discloses a combined ablation and puncture apparatus. The combined ablation and puncture apparatus comprises a lining core, a puncture needle, and an ablation instrument; a head-end electrode is arranged at the head end of the lining core; a cavity channel is arranged inside the puncture needle so as to output plasma-generating media from the head end of the puncture needle; the lining core is in detachable fit with the interior of the puncture needle; the head-end electrode extends from the head end of thepuncture needle; a ring electrode matching the head-end electrode is arranged at the head end of the puncture needle; the lining core and the puncture needle are both connected with the ablation instrument; and the ablation instrument is used for controlling operation of the head-end electrode and the ring electrode. The purpose of the invention is to provide a combined ablation and puncture apparatus which is capable of safely and efficiently treating spinal cord lesions in human body.

Description

technical field [0001] The invention relates to the field of ablation treatment devices, in particular to a combined ablation and puncture device. Background technique [0002] Under the action of an electric field, particles of different electrical properties inside the substance will be subjected to an electric field force in the opposite direction. When the electric field is strong enough, the positive and negative particles cannot gather together, and eventually become ions that can move freely, and the substance transforms into an ionic state. This transformation can be transformed at room temperature, that is, it becomes low-temperature plasma. [0003] The working principle of low-temperature plasma ablation is to excite the medium (Nacl) with a specific 100kHz ultra-low frequency electric energy to generate plasma, and in the temperature range of 40-70°C, the sound waves generated by the "plasma" break the molecular bonds of the target tissue , to directly split bio...

Problems solved by technology

[0007] However, when dealing with diseases on the spine, especially for spinal cord lesions (such as hyperplasia, etc.), there is no ideal ablation method. Traditional radiofrequency ablation or cryoablation, because the spinal cord is very fragile, the temperature is too high. If it is too high or too low, it cannot be used for spinal cord ablation, and it will cause irreversible huge losses to the patient. Moreover, the lesion of the spinal cord is based on the "segment". , then basically the spinal cord corresponding to this spine will have lesions, such as myeloid hyperplasia, then at this time, it is difficult to treat, generally it is drug treatment, it is difficult to achieve the therapeutic effect, and the treatment takes a long time
