Description

Adjustable periodontal endoscope sheath and adjustable periodontal endoscope

Technical Field

The present utility model relates to an auxiliary instrument for oral treatment, and more particularly to an adjustable periodontal endoscope sheath and an adjustable periodontal endoscope for use in cooperation with a periodontal endoscope.

Background

Periodontal disease, especially periodontitis, is the highest disease species in the current oral diseases, and symptoms such as gingival bleeding, periodontal pocket, abscess, loosening of teeth and the like can occur along with the development of the disease if the treatment is not timely carried out. The main causative factors of periodontitis are calculus and plaque that form on the surface of the tooth root.

Periodontal scaling is the most basic treatment for a variety of periodontal diseases, and subgingival scraping and root planing are important steps in these, especially for patients who have formed periodontal pockets, subgingival scraping is the primary means of scraping calculus and plaque from the root surface of teeth Zhou Daina.

At present, a common treatment process is to scrape the diseased tissue of the root surface and scattered dental calculus and dental plaque around the root surface of teeth by using a fine subgingival scraping device according to the reflection and hand feeling of a mouth mirror, so that the root surface is smooth, and whether the subgingival dental calculus is scraped cleanly or not and whether the tooth root surface is smooth or not must be carefully detected by using a sharp probe during or after scraping treatment so as to determine scraping effect.

Because the scraping treatment is carried out only by the reflection of the mouth mirror and the hand feeling, the scraping treatment condition in the periodontal pocket can not be observed well, and therefore, the conditions of tissue injury or unclean scraping treatment are easy to occur. To avoid this, periodontal endoscopy is currently used to assist the subgingival scraping procedure.

The current periodontal endoscope is generally provided with a lens sleeve, the outlet end of the lens sleeve is a conical inclined surface, the conical inclined surface faces the tooth side, and the endoscope extends out from the outlet of the lens sleeve and looks towards the tooth side.

The structure and the angle between the cone-shaped inclined plane of the current mirror sleeve outlet and the handle are fixed, so that the cone-shaped inclined plane cannot face the tooth side well due to the limitation of the handle easily in the observation process, thereby affecting the observation effect, and therefore, the current mirror sleeve needs to be improved to be better clinically used.

Disclosure of Invention

According to the adjustable periodontal endoscope sheath, the direction of the conical surface at the outlet of the sheath can be adjusted through the adjusting mechanism arranged on the sheath, so that the problem that the conical surface at the outlet of the sheath cannot face the tooth side due to the limitation of the handle in the clinical use at present is solved, and the application range is wider in the clinical use.
