Description

Drainage plug for buried anti-tooth extraction Technical Field The utility model relates to the technical field of oral surgical instruments, in particular to a drainage plug for buried anti-scaling tooth extraction. Background The teeth cannot grow out normally due to insufficient oral space or poor wisdom tooth position, and are commonly found in the 3 rd molar of the mandible. This condition often results in problems such as caries in adjacent teeth, swelling and pain in gums, and tooth displacement. Therefore, it is necessary to perform a resist tooth extraction operation. In order to solve the problem, the traditional buried anti-tooth extraction operation can also place a drainage strip to help the tooth extraction wound to drain, but the drainage strip needs to be replaced or taken out, new granulation tissues are easy to tear during replacement, and the patient visit times are increased. Disclosure of utility model In order to overcome the above-mentioned drawbacks of the prior art, the present utility model is directed to a drainage plug for a buried anti-tooth extraction, which is vertically implanted in a dental socket wound after the anti-tooth extraction, and helps tissue seepage after the operation to be led out through a central drainage cavity, so as to avoid swelling infection of the wound, and solve the problems set forth in the above-mentioned background art. The utility model solves the technical problems by adopting the technical scheme that the drainage plug for the embedded anti-scaling tooth extraction comprises: The main body structure is internally provided with a drainage channel; the side wall of the main body structure is provided with at least one fixing unit for anchoring the main body structure to the tissues around the alveolus; one end of the main body structure is provided with an expandable limiting part which is matched with the inner wall of the tooth socket to prevent the main body structure from falling out; The main structure is composed of a plurality of layers of degradation materials and comprises an outer functional layer and an inner supporting layer. As a further improvement of the utility model, the main body structure is a drainage tube, and a drainage channel in the drainage tube is provided with a hollow drainage cavity. As a further improvement of the utility model, the diameter of the hollow drainage cavity is 2-3mm, and the outer diameter of the drainage tube is 4-5mm. As a further improvement of the utility model, the expandable limiting member is a collapsible umbrella-like wing having an expanded diameter larger than the socket opening diameter. As a further improvement of the utility model, the unfolding diameter of the umbrella wing is 8-10mm, and the opening force of the umbrella wing is 0.5-1.0N. As a further improvement of the present utility model, the fixing unit includes at least two opposite needle holes opened at the side wall of the drainage tube for suture-fixing the drainage tube to the gingiva. As a further improvement of the utility model, the degradation rate of the outer functional layer is greater than the degradation rate of the inner support layer. As a further improvement of the utility model, the outer functional layer is a chitosan or polylactic acid composite film, and the inner supporting layer is a gelatin or beta-tricalcium phosphate porous bracket. Compared with the prior art, the utility model has the beneficial effects that: 1. According to the utility model, continuous effusion diversion is realized through the drainage channel in the main structure, and effusion in a closed environment is reduced, so that swelling and infection probability is reduced, and through the double-retention design of the side wall fixing unit and the expandable limiting component, the fitting property of the drainage plug and the alveolus is enhanced, the postoperative escape is prevented, the continuous effectiveness of the drainage channel is ensured, the multilayer degradation materials are adopted, the outer functional layer rapidly degrades and drains, the inner supporting layer slowly degrades and supports, the device is prevented from being taken out, the tearing of new tissues is avoided, and the comfort level of a patient is improved. 2.
