A Simple and Easy Drainage Device for Jaw Cyst

Abstract

The invention discloses a simple and convenient drainage device for jaw cyst. The device comprises a drainage outer tube, the side face of the drainage outer tube is symmetrically provided with two through holes, and support pillars are slidably connected inside the two through holes; the end portions of the support pillars are provided with two fixed plates, a connecting spring is connected between the two fixed plates, and the side face of the inner cavity of the drainage outer tube is provided with an internal thread; a drainage inner tube is connected inside the drainage outer tube, the outer surface of the drainage inner tube is provided with an external thread, the drainage outer tube is in threaded connection with the drainage inner tube through the external thread and the internalthread, and the end portion of the drainage inner tube is provided with a ring washer. The simple and convenient drainage device for the jaw cyst is spirally fixed through a nut and bolt principle, the fixation is firm, redundant additional devices are not involved, a drainage mouth is concavely arranged inside a bone cavity and can not protrude from a mouth cavity, foreign body sensation of a patient is not obvious, the drainage mouth is made into a pintle hole form to match an injector for use, it is convenient to flush, sterilize and attract, and the blocking and the infection are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a simple and easy-to-operate jaw cyst drainage device. Background technique [0002] Jaw cyst is a benign lesion of the jaw with a high incidence in oral and maxillofacial surgery. Depending on the size, location, and adjacent tissue relationship of the cyst, such as teeth, maxillary sinus, mandibular canal, and bone continuity, enucleation, partial jaw resection, and pocket surgery can be selected. When the cyst is large and involves healthy teeth, nerve bundles and other important tissue structures, the existing treatment methods, such as partial jaw resection and enucleation, may damage the surrounding important tissue structures, resulting in alveolar bone damage. Loss of continuity, extraction of adjacent teeth, facial deformities, etc. And if it is to protect important tissue structures, it may greatly increase the chance of recurrence. With the progressive promo...

Problems solved by technology

However, pouch surgery needs to obtain continuous cystic drainage. Many drainage devices have been invented clinically, but they all have the disadvantages of large volume, easy to fall off, and personalized preoperative production.

There are obvious foreign body sensations in the patient's mouth, it is difficult to clean, and the patient's compliance is poor.

Such as the earlier active cyst plug or occluder, there are also some other devices that require a certain thickness of the cyst wall or the disadvantages of surgical implantation
