Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a dental root canal irrigation needle with good cleaning effect. Background Technology
[0002] With the advancement of technology, people are paying increasing attention to oral health, especially dental health. Root canal treatment is the most common method for treating dental diseases and is the most effective treatment for pulpitis and periapical periodontitis internationally. During root canal treatment, root canal irrigation is a crucial step.
[0003] Root canal irrigation involves injecting irrigation fluid through an irrigation cannula to clean away debris and remaining pulp tissue from the root canal. However, the pressure of the irrigation fluid is relatively low, making it insufficient to completely remove any remaining pulp tissue deep within the root canal. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dental root canal irrigation needle with good cleaning effect. This solves the problem that root canal irrigation, which involves injecting irrigation fluid through an irrigation tube to clean debris and residual pulp tissue from the root canal, has relatively low pressure and cannot clean the pulp tissue that has not completely detached from the deep part of the root canal.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dental root canal irrigation needle with good cleaning effect includes a needle hub, one end of which is provided with a threaded connection part, and the other end of which is provided with a needle tube connection part coaxially. Force plates are symmetrically provided on both sides of the needle tube connection part. A needle tube is provided at the end of the needle tube connection part away from the needle hub. Fluid outlet holes communicating with the inner cavity of the needle tube are symmetrically opened on both sides of the end of the needle tube away from the needle tube connection part. Several flexible columns are provided on the outer wall of the needle tube between the two fluid outlet holes.
[0007] As a preferred technical solution of this utility model, the needle seat, needle tube connection part, needle tube and flexible column are integrally formed.
[0008] To facilitate medical staff in selecting the irrigation needle according to the irrigation angle, thereby improving the treatment effect, the needle tube connection part has a straight or bent structure.
[0009] To ensure the connection strength between the flexible column and the needle, and to avoid damage to the oral cavity or treatment area caused by the flexible column, the flexibility of the flexible column gradually increases from the end closer to the needle to the end farther away from the needle.
[0010] To further ensure the safety of the flexible column during use, the end of the flexible column away from the needle tube is hemispherical.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention, through the design of a flexible column, can bring out the pulp tissue inside the root canal during irrigation, thereby improving the cleaning efficiency and effect of the irrigation needle. The needle tube connection part has two structures, a straight one and a bent one, which makes it easier for medical staff to select the irrigation needle according to the irrigation angle, thereby further improving the treatment effect and applicability. The threaded connection part on the needle hub improves the tightness of the needle hub installation, avoiding the risk of accidental dislodgement due to loose installation and the danger of accidental swallowing by the patient.
