Description

A simple and easy drainage device for jaw cyst

technical field

The invention relates to the technical field of medical devices, in particular to a simple and easy-to-operate jawbone cyst drainage device.

Background technique

Jaw cysts are benign lesions of the jaw with high morbidity in oral and maxillofacial surgery. Enucleation, partial jaw resection, and pouch surgery are optional for cysts depending on their size, location, and adjacent tissue relationships, such as teeth, maxillary sinus, mandibular canal, and bone continuity. When the cyst is large and affects healthy teeth, nerve bundles and other important tissue structures, existing treatment methods, such as partial jaw resection and enucleation, may damage the surrounding important tissue structures and cause alveolar bone loss. Loss of continuity, extraction of adjacent teeth, and facial deformities. In order to protect important tissue structures, it may greatly increase the chance of recurrence. With the gradual and in-depth promotion of the minimally invasive concept, more and more bag-shaped procedures are advocated for large jaw cysts. The pouch ostomy is performed on the cystic bone wall through a small surgical operation, so that the cystic cavity is connected with the external environment, the hydrostatic pressure in the cystic cavity is eliminated, and the bone resorption factors are eliminated, so that the cyst lining epithelium changes and the cyst wall thickens. The cyst cavity shrinks and the bone regenerates. When the cyst is shrunk enough to not involve the surrounding important tissue structures, enucleation is performed, which greatly reduces the risk of surgery and improves the quality of life after surgery. After nearly ten years of clinical practice, it has been proved that pouch surgery can effectively reduce the complications of traditional surgical treatment and obtain good shape and function recovery. However, pouch surgery needs to obtain continuous cyst cavity drainage. Many drainage devices have been invented clinically, but they all have the disadvantages of being bulky, easy to fall off, and personalized preoperatively. There are also problems such as obvious foreign body sensation in the patient's mouth, difficult to clean, and poor patient compliance. Such as the earlier active cyst plugs or occluders, there are also other devices that require a certain thickness of the cyst wall or require surgical implantation.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

1-2, the present invention provides a technical solution: a simple and easy-to-operate jawbone cyst drainage device, including a drainage outer tube 1, the drainage outer tube 1 is put into the bone cavity, and the fastener 4 is tightly attached At the outer wall of the bone cavity, two through holes 2 are symmetrically arranged on the side surface of the outer drainage tube 1. The through holes 2 are slidably connected with a top column 3. The end of the top column 3 is provided with a fixed plate 12. The two fixed plates 12 A connecting spring 11 is connected between them. When the device needs to be disassembled, after the inner drainage tube 7 is taken out, the fixing plate 12 is subjected to the pulling force of the connecting spring 11, so that the top column 3 enters the through hole, and then the outer drainage tube 1 is taken out, The side surface of the inner cavity of the outer drainage tube 1 is provided with an inner thread 9, and the outer drainage tube 1 is connected with an inner drainage tube 7, and the diameter of the inner drainage tube 7 is matched with the needle hole of the syringe, so as to achieve the drainage effect, and at the same time cooperate with the application of the syringe. For flushing and suction, a miniature negative pressure suction device can also be used in conjunction. The outer surface of the drainage inner tube 7 is provided with an outer thread 8, and the drainage inner tube 7 is threadedly connected into the inner cavity of the drainage outer tube 1 through the outer thread 8 and the inner thread 9. , when the arc head 13 at the end of the inner drainage tube 7 is in contact with the arc plate 10, the top column 3 is subjected to an outward pressing force through the fixing plate 12, so that the top column 3 slides out of the through hole 2 and pushes against the bone On the inner wall of the cavity, it plays a fixed role. The drainage outer pipe 1 and the drainage inner pipe 7 are threadedly connected with the inner thread 9 through the outer thread 8.
