Energy-controllable electrosurgical electrode

Abstract

The invention discloses an energy-controllable electrosurgical electrode. The energy-controllable electrosurgical electrode comprises an electrode body, wherein a plurality of salient points are arranged on the spherical surface of the electrode body, the salient points are used for discharging and blood coagulation, the adjacent salient points are separated by an insulating coating, the plurality of salient points are distributed according to a certain rule, and the number of the salient points is solved by utilizing a regular hexagon model. Compared with the traditional electrosurgical spherical electrode, the energy-controllable electrosurgical electrode has the advantages that the salient points are distributed on the spherical surface of the electrode body according to a certain rule, on one hand, the relatively large current density in the use process of the electrode is guaranteed, the blood coagulation rate is increased, the thermal injury in the blood coagulation process is reduced, the temperature consistency of the periphery of the human tissue of the salient points is guaranteed, and the harm to the human body is reduced; and on the other hand, the energy released by the salient points can guarantee the consistency of the thermal injury of the human tissue in the blood coagulation process and the accurate and controllable release of the energy, the accurate operation of a user can be guaranteed, and the secondary injury caused by multiple times of blood coagulation at the same human tissue position is avoided.

Description

technical field [0001] The invention mainly relates to the technical field of medical equipment, in particular to an energy-controllable electrosurgical electrode. Background technique [0002] Surgical electrode is a common minimally invasive surgical instrument in hospital surgery. Since it was invented, it has gradually replaced traditional surgical blades because of its advantages such as easy healing of scars, low infection rate and greatly reduced operation time. It has become more and more widely used clinically, and has become one of the most important medical special equipment in hospital operating rooms. [0003] Surgical electrodes used in electrosurgery include blade type, needle type, wire type, and ball type. Traditionally, the shapes of surgical electrode blades are blade-type, needle-like, and wire-like structures. These structures have advantages in specific use states. For example, the advantage of blade type is cutting, while needle-like and wire The adv...
