An implantable bone cyst fenestration drainage system

Abstract

The invention discloses an implantable bone cyst fenestration drainage system, which belongs to the technical field of stomatology and consists of four parts: a fenestration drill, a self-tapping cyst plug, a silicone plug and a torque wrench. The self-tapping cyst plug stabilizes the cyst plug itself and avoids possible damage to adjacent teeth. At the same time, the self-tapping cyst plug has good biocompatibility, which is beneficial to osteogenesis and gingival formation. The implantable bone cyst fenestration drainage system is adopted, and the operation and cyst plug placement are completed at one time, which saves operation time, avoids second-stage operation, and reduces the number of follow-up visits for patients. The invention uses materials that do not need to be frequently replaced, and is convenient for medical personnel and patients to flush themselves, and the flushing is more thorough and the drainage is more sufficient. In addition, the present invention uses materials with strong X-ray opacity, which is convenient for observing the position, angle and relationship with the cyst cavity and the like of the cyst plug through X-ray film.

Description

technical field [0001] The invention relates to the technical field of stomatology, in particular to an implantable bone cyst fenestration drainage system. Background technique [0002] During the operation of fenestration decompression, the first choice is to extract the loose teeth of more than 2° in the lesion area, expand the extraction socket, and form a drainage channel; when there is no need to extract the lesioned teeth, the flap is flapped at the weakest part of the maxillary protrusion to remove the residual bone wall on the surface. Form an open window. The cyst wall around the window was scraped and sent for pathological examination. Then the cyst cavity needs to be flushed. For multilocular cysts, the bony septum should be removed as much as possible to make the cyst cavity communicate with the window. The window was enlarged to at least 1cm×2cm, and the mucosa around the window was sutured with bag forming. Fill with iodoform gauze. [0003] One to two week...

AI Technical Summary

Problems solved by technology

[0005] The existing cyst plug is made 1 to 2 weeks after the operation, and the patient needs to see a doctor again. At this time or earlier, the patient may still have pain in the operation area and symptoms of limited mouth opening, which cannot cooperate with the impression. The wound may be closed and a second window opening is required

At the same time, the cyst plug itself is not good in retention, and it needs to be retained by the adjacent teeth, which may loosen the adjacent teeth in the long run

Cyst fluid and flushing fluid are not easy to flow out, it is difficult for patients to flush effectively by themselves, and the hoses used need to be replaced frequently

In addition, the X-ray opacity of the materials used is not strong, and it is difficult to observe the position, angle, and relationship with the cyst cavity through X-ray films.
