Background
The principle of the plasma electrode knife head is that sodium ions in normal saline (electrolyte) are excited by a radio frequency electric field, an ionized plasma layer is generated between the operation electrode dipoles, and the highly excited plasma can rapidly break molecular bonds between tissues and is mainly used for cutting, ablating, hemostasis treatment, stripping of pathological tissues and the like of the pathological tissues.
The in-ear plasma electrode tool bit is a common plasma electrode tool bit, and a bipolar structure is formed by an inner electrode and an outer electrode, and is mainly used for in-ear mirror tympanic membrane repair operation, in-ear mirror tympanic cavity forming operation, in-ear mirror nerve decompression operation, total-ear mirror head-cape vestibular schwannoma excision operation and the like. In the operation process, the plasma electrode tool bit needs to be inserted into the external auditory canal, and the external auditory canal is not a straight channel but is slightly S-shaped and bent, but the existing in-ear plasma electrode tool bit is mostly in a straight rod shape, and the bending resistance is poor, so that a special stripping instrument needs to be replaced to remove a focus after the operation, and the use is very inconvenient.
Applicant searches and finds that chinese patent publication No. CN218128736U (hereinafter referred to as "comparative patent") discloses an in-ear electrode with a peeling function, in which an inner electrode working portion extends toward a direction deviating from an axis of an outer electrode, so that the electrode working portion and the outer electrode form a peeling instrument, which facilitates peeling of focal tissue by stamping, scraping, digging, hooking, etc. during an operation. However, in practice, the applicant found that the external electrode in the comparative patent is still in a straight rod shape, the internal insulating sleeve and the internal electrode extend obliquely and linearly relative to the external electrode, the fitting rate of the external auditory canal outline of the human body is low, the inconvenient situation still exists when the focal tissue is peeled off, and the working position of the internal electrode is in a sheet shape, and the pathological tissue still cannot be peeled off well, so that the defects of long operation time and the like are caused.

The utility model aims to solve the technical problems that: an in-ear plasma electrode tool bit which is convenient for stripping pathological tissues and reducing operation time is provided.
In order to solve the technical problems, the utility model provides an in-ear plasma electrode tool bit, which comprises an inner electrode and an outer electrode, wherein an inner insulating sleeve is arranged between the inner electrode and the outer electrode, and one end of the inner electrode extends out of the outer electrode and the inner insulating sleeve to form an inner electrode working part; the inner electrode adopts an electrode wire, and the working part of the inner electrode is bent into a spoon-shaped circular ring.
The utility model adopts the electrode wire as the inner electrode, is convenient for concentrating plasma in the operation process, is easier to cut pathological tissues and stop bleeding, and the working part of the inner electrode is made into a spoon-shaped circular ring shape by a processing mode of bending and arc-shaped bending, so as to form a shape similar to an earpick, and is matched with the electrode wire, when the focus is stripped, the wire-cutting and digging state is formed, the use is more convenient, thereby improving the product performance, improving the operation efficiency and shortening the operation time.

Detailed Description
Example 1
The embodiment relates to an in-ear plasma electrode cutter head, which comprises an inner electrode 1 and an outer electrode 3, wherein an inner insulating sleeve 2 is arranged between the inner electrode 1 and the outer electrode 3, the inner insulating sleeve 2 is preferably made of ceramic, and the outer electrode 3 is preferably made of a metal tube. One end of the inner electrode 1 protrudes from the outer electrode 3 and the inner insulating sleeve 2 to form an inner electrode working portion 6. The electrode wire is adopted as the inner electrode 1, so that plasma can be concentrated in the operation process, the inner electrode working part 6 is bent into a spoon-shaped circular ring, and when the excised focus is stripped, the wire cutting and digging state is formed, and pathological tissues are easier to cut and hemostasis is achieved.
In the implementation, the electrode wire can be bent in a bending and arc-shaped bending processing mode so as to achieve the shape of an ear pick, thereby more conveniently peeling focus tissues and having better peeling performance. The length of the adult auditory canal is generally 2.5 to 3.5cm and the diameter is about 0.7cm, and therefore, it is preferable that the circular shape of the inner electrode working part 6 has a diameter of 1.5mm to 5.0mm.
The present embodiment can also be modified as follows:
1) As shown in fig. 1 and fig. 2, one end of the outer electrode 3 and one end of the inner insulating sleeve 2, which is close to the inner electrode working part 6, are bent to a shape matched with the external auditory canal of a human body, namely, the end part of the outer electrode 3 (bent metal tube) is bent, the matched part of the inner insulating sleeve 2 made of ceramic and the metal tube is made to be in the same shape, the exposed part of the insulating sleeve 2 is obliquely and arcuately extended, and the oblique angle is between 15 degrees and 75 degrees, so that the inner insulating sleeve can be more fit with the inner outline of the external auditory canal of the human body during operation, and the bent part of the outer electrode is abutted against the junction of the external auditory canal and the face, so that the outer electrode is similar to a lever, thereby facilitating the position fixing and force application of the inner electrode working part 6, and more facilitating operation and peeling of pathological tissues.
2) As shown in fig. 1 and 3, the end of the inner insulating sleeve 2 near the electrode working portion 6 is provided with a plurality of slope surfaces 5, so that the blocking of the inner insulating sleeve 2 to the electrode working portion 6 is reduced in the operation process, and the condition of focal tissues is convenient to observe.
Example two
The difference between this embodiment and the first embodiment is that: the inner insulating sleeve 2 in this embodiment is not made of ceramic any more, but is made of an elastic material, and at this time, by reasonably adjusting the shape and size of the inner insulating sleeve 2, the inner insulating sleeve 2 can be completely attached to the external auditory canal during operation, so that the position of the inner electrode working portion 6 can be ensured to be fixed during operation, thereby further improving the convenience of operation and the rapidity of peeling off the lesion tissues.
