Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments for apical surgery, in particular to a scraping auxiliary instrument for apical surgery. Background Art

[0002] Apical surgery, also known as apicoectomy, is a dental procedure commonly performed to treat teeth that have failed root canal treatment or are infected. The main goal of this procedure is to remove infected or diseased tissue from the root of the tooth and repair the damaged root apex area in order to save the tooth.

[0003] During apical surgery, it is often necessary to scrape away the granulation tissue in the bone cavity. However, due to the fibrosis of the granulation tissue, it becomes tough and adherent. Simple scraping is time-consuming and labor-intensive, resulting in inability to completely scrape it away. The remaining granulation tissue will slow down the healing of the apical bone defect and may mask some of the causes of apical inflammation, leading to failure of the apical surgery.
