Radio frequency melting electrode for otitis media minimally invasive surgery and using method of radio frequency melting electrode

Abstract

The invention provides a radio frequency melting electrode for an otitis media minimally invasive surgery and a using method of the radio frequency melting electrode. The radio frequency melting electrode comprises a handle and an electrode which are mutually connected, wherein the electrode adopts a tubular structure, and comprises an inner tube electrode and an outer tube electrode; the inner tube electrode and the outer tube electrode are connected with two poles of a power source; the tube body of the outer tube electrode sleeves the tube body of the inner tube electrode; the headend of the outer tube electrode and the headend of the inner tube electrode are in the same direction and are exposed to form the electrode headend of the electrode; the external surface of the inner tube electrode is an insulation surface; and the tube body of the inner tube electrode and the tube body of the outer tube electrode are mutually isolated, and the headends of the inner tube electrode and theouter tube electrode can be electrically conducted through normal saline, so that a plasma field is formed by the electrode headend to perform melting and drilling on tympanic membrane tissue. A thinking set of a conventional high-temperature puncturing surgery manner of mechanical puncturing, electric burning or laser and the like is broken through, low-temperature plasma principle is utilized toform the plasma field in the electrode headend, and melting and drilling are performed on the tympanic membrane tissue under a low temperature, so that the efficiency and the treatment effect of theotitis media minimally invasive surgery are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiofrequency ablation electrode for minimally invasive surgery on otitis media and a method for using the same. Background technique [0002] Otitis media is an inflammatory lesion involving all or part of the structure of the middle ear (including the Eustachian tube, tympanic cavity, tympanic antrum, and mastoid air cells), and is more common in children. There are different types of otitis media, and the treatment is also different. It can be roughly divided into two types: 1. Secretory otitis media, which is mainly caused by blocked Eustachian tube. fluid, forming a secretory otitis media. As long as there is no structural abnormality, after the cold is cured, the nose will be ventilated, the function of the Eustachian tube will recover, and the fluid in the middle ear will be discharged, and the secretory otitis media will be considered a self-healing. You can ...

Problems solved by technology

However, it has been found clinically that the traditional tympanic membrane puncture surgery has the following significant defects: because the mechanical puncture is a mechanical injury to the tympanic membrane tissue, the tympanic membrane heals too quickly, about one week, and the complete discharge of the effusion usually takes at least one month, thus As a result, the intratympanic effusion heals before being drained, requiring re-puncture, or even more repeated punctures, resulting in cumbersome operations for the doctor, increasing the pain of the patient, and delaying the treatment process. On the other hand, it is difficult to control the penetration depth during the puncture operation , if the tip of the myringotomy knife penetrates too deep, it is easy to injure the vascular nerve plexus on the surface of the promontory tympanum mucosa in the inner wall of the middle ear cavity, which has low safety and requires high operating requirements for doctors

[0004] Another method that can be adopted is laser perforation surgery. Its defect is that it will cause permanent burns to the tympanic membrane tissue, and it is difficult to heal the tympanic membrane after treatment. This is obviously not the result that doctors and patients hope for.
