Description

Simple and easy jaw cyst drainage device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a simple and easy jaw cyst drainage device.

Background

The jaw cyst is a benign lesion of the jaw bone with high incidence rate in oral and maxillofacial surgery. Depending on the size, location and adjacent tissue relationships of the cyst, such as continuity of the teeth, maxillary sinus, mandibular canal and bone, lines of enucleation, partial jaw resection and pockets may be selected. When cysts are large and spread to healthy teeth, nerve bundles and other important tissue structures, existing treatments, such as partial jaw resection, enucleation, may damage the surrounding important tissue structures, resulting in loss of continuity of alveolar bone, extraction of adjacent teeth, facial deformity, etc. If important tissue structures are protected, the recurrence probability can be greatly increased. With the gradual deep popularization of the minimally invasive concept, more and more bag-shaped surgeries are advocated for large jaw cyst. The bag-shaped operation makes an opening on the wall of the cyst bone through a small surgical operation, so that the cyst cavity is communicated with the external environment, the hydrostatic pressure of fluid in the cyst cavity is eliminated, and the bone absorption factors are eliminated, thereby changing the epithelium of the cyst lining, thickening the cyst wall, reducing the cyst cavity and regenerating adjacent bones. When cysts shrink to the point that important surrounding tissue structures are not affected, then enucleation is performed, thereby greatly reducing the risk of operation and improving the quality of life after the operation. Clinical practice in recent ten years proves that the bag-shaped operation can effectively reduce the complications of the traditional surgical operation treatment and obtain good shape and function recovery. However, the bag-shaped operation needs to obtain continuous sac cavity drainage, and a plurality of drainage devices are invented clinically, but all the devices have the defects of large volume, easy shedding and personalized manufacture before the operation. The problems of obvious foreign body sensation, difficult cleaning, poor patient compliance and the like when the mask is worn in the mouth of a patient. Such as the earlier active cyst stoppers or obturators, and other devices that require a thickness of the cyst wall or require surgical implantation.
