Description

External excimer lamp of high pressure

Technical Field

The utility model belongs to the technical field of ultraviolet light sources, and particularly relates to a high-voltage external excimer lamp.

Background

The dental implant is implanted into the upper and lower jawbone of the edentulous part of human body by means of surgical operation, and after the operation wound is healed, a repairing abutment and a device for dental crown are installed on the upper part of the dental implant. For modern oral cavity, the implant is widely used for tooth loss and restoration due to its features of beauty, comfort and long life, and is called the third pair of human teeth.

The hydrophilic dental implant often has more excellent bioactivity, and a series of researches show that the hydrophilic dental implant has a promotion effect on the differentiation of osteocytes and is particularly effective on early osseointegration. However, the contact angle of the existing implant is generally higher (more than 90 degrees), and the hydrophilicity of part of hydrophilic implant is obviously reduced after the part of hydrophilic implant is placed for a period of time.

Ultraviolet irradiation is a process by which the surface of an implant can be modified prior to dental implant surgery to regain a hydrophilic surface. Although the corresponding excimer lamp can enable the implant to reach the hydrophilic level to a certain extent, the excimer lamp has not been popularized in a large range in the market yet, the main reason is that the high voltage of the existing coaxial excimer lamp is arranged on an inner electrode, when the surface of the implant is modified by the excimer lamp, the implant extends into the inner tube, and the inner electrode is easy to generate creepage with the implant; in order to overcome the creepage problem, some proposals have been made to arrange a quartz tube in the inner tube, but when arranging a quartz tube, the ultraviolet irradiation intensity will be reduced, and the process is complicated and the cost is high.
