Description

Technical Field

[0001] The invention relates to a ceramic head applied to a plasma surgical knife head. Background Art

[0002] Plasma surgical blades are medical devices used in conjunction with plasma surgical systems for minimally invasive treatment, which can achieve the purpose of treatment quickly and safely. Plasma surgical blades use the host to provide a special electric field with high radio frequency to act on the front end of the blade, forming a plasma layer in physiological saline and human tissue fluid. The host monitors and optimizes the voltage amplitude and frequency applied to the plasma thin layer in real time according to different physical signs and working environment types, achieving functions such as tissue cutting, vaporization, and coagulation without generating excess heat, thereby achieving the purpose of treating related diseases.

[0003] The circular ceramic head of the existing plasma surgical blade has a relatively small field of view observed through the endoscope during minimally invasive surgery, which is not conducive to finding the affected area. In addition, due to the circular structure, the distance between the two electrodes is increased, and the electrode energy cannot be quickly concentrated, which affects the surgical effect and efficiency.

[0007] Preferably, there is an arc transition between the discharge hole and the inclined surface of the ceramic head.

[0008] Preferably, arc transition is adopted at the edge connection of the ceramic head, and the arc radius is 0.05-0.15mm.

[0009] Preferably, the angle between the first inclined surface and the connecting member is 145-177°.

[0010] Preferably, the angle between the first inclined surface and the inclined surface of the top of the ceramic head is 70-86°.

[0012] Preferably, the diameters of the three electrode holes and the three first electrode holes are 0.2-0.5 mm.

[0013] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention provides a ceramic head for a plasma surgical blade, which adopts an irregular quadrilateral structure, and the upper and lower ends of the ceramic head are changed from arcs to straight lines, thereby shortening the distance between the two electrodes, so that the electrode energy can act on the affected area more quickly, and because the area of ​​the ceramic head is reduced, the energy of the electrode is more concentrated and the effect is better. In addition, the smaller area of ​​the ceramic head also increases the field of view of the endoscope in minimally invasive surgery, making it easier and faster to find the affected area and reducing surgical risks.
