Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical machinery, especially an electrode for treating the electro-surgical operation of trichiasis, which is used for treating the surgical operation of upper and lower eyelid trichiasis. BACKGROUND

[0002] For adult partial trichiasis with a small number of eye and face inversion, the following treatment schemes are usually adopted:

[0003] (1) Pulling out method: when the number of trichiasis is not large, the trichiasis can be directly pulled out with a eyelash forceps, which is simple and effective, but since the hair follicle of the eyelash is not damaged, it is easy to recur within a few weeks. The eyelashes that grow out again will be thicker and harder, which will stimulate the cornea, so pulling out is only used in the case where the conditions are poor and there is no other way, or in the case where other methods have been tried without success, and it is a last resort;

[0004] (2) Electrolysis method: electrolysis destroys the hair follicle and pulls it out, sometimes it needs to be repeated several times to achieve the desired effect, and the success rate is about 10-20%;

[0005] (3) Cryotherapy: it can eliminate a large number of trichiasis, and the potential complications are: skin pigment loss, postoperative facial margin incision, damage to the meibomian gland and influence on tear film stability;

[0006] (4) Laser treatment: laser separation is effective for a small number of scattered trichiasis;

[0007] (5) Surgical excision of hair follicle under microscope: the hair follicle can be excised under microscope; if the number of trichiasis is large, it can be wedge-shaped excision or anterior lamellar excision, which is effective for local clustered trichiasis that cannot be treated by other methods.

[0008] The utility model aims at improved surgical operation for trichiasis. The preferred use of electrosurgical current is higher than 1.5 MHz, preferably higher than 3 MHz. Under these high frequencies (usually referred to as radiosurgery), the destruction is completed by volatilizing the intracellular fluid at the emission electrode contact point, which mainly causes small lateral heat diffusion, so the damage to adjacent cell layers is small. High-frequency ablation is a new operation that can be used to treat partial trichiasis, which has no repeatability, and the wound is recovered within 3 days. A superfine radiofrequency probe containing an insulating layer is needed during the operation to ablate the hair follicle of the lower eyelid trichiasis.

[0009] Our new electrode is characterized by a fine needle bare active sharp tip portion, which extends beyond the exposed tip portion is completely insulated by a thin electrically insulating coating. The portion of the needle adjacent to the tip is made insulating to avoid excessive heating and to concentrate the high frequency current at the needle tip. Electrosurgical procedures using needle electrodes have the important advantage of concentrating the current that will cause tissue damage at the desired tissue, with minimal damage to surrounding tissue, relatively fast procedures, and little pain or trauma to the patient.
