Description
Technical Field
The invention relates to the technical field of drainage tubes for incision and drainage of interstitial infection abscesses in oral and maxillofacial surgery, in particular to a drainage tube for incision and drainage of interstitial infection abscesses in oral and maxillofacial surgery.
Background
The oral cavity and maxillofacial region is positioned at the starting ends of the digestive tract and the respiratory tract, and is directly communicated with the outside through the oral cavity and the nasal cavity, and the anatomical structure, the temperature and the humidity are all suitable for breeding and propagating bacteria, so that a large amount of microorganisms exist in normal times. Infection can occur when these sites are affected by trauma, surgery, or low systemic resistance. The oral and maxillofacial region has many potential fascia gaps communicated with each other, loose connective tissues are contained in the gaps, and when infection invades the gaps, suppurative inflammation dissolves and liquefies the loose connective tissues, inflammatory products fill the gaps, and then obvious gaps appear. The infection can be limited in one gap, and can also spread along with weak tissues to form a plurality of dispersive gap infections, and the oral and maxillofacial infection can spread to the neck and mediastinum along the anterior spaces of the trachea, the visceral vascular space and the visceral vascular posterior space through the deep fascia of the neck to form wider and serious neck and mediastinal abscesses to endanger life.
Therefore, timely treatment is needed when oral and maxillofacial space infection occurs. The surgical treatment is mainly abscess incision and drainage. After the abscess incision drainage operation, the smooth abscess drainage is ensured by remaining a drainage object (a drainage tube or a drainage sheet), but the current drainage object has the following defects:
firstly, the method comprises the following steps: at present, no special drainage matter for incision and drainage of the gap infection abscess in oral and maxillofacial surgery exists. The traditional method is to use a rubber sheet cut into strips by latex gloves as a drainage sheet, or to use a negative pressure drainage ball, a catheter and an oxygen uptake leather strip to cut and then manufacture a drainage tube on the spot, but has the following problems: the preparation is needed in the field, the use is inconvenient, and the time is consumed; the preparation method is easy to cause secondary pollution, wound pollution and even iatrogenic infection.
Secondly, the method comprises the following steps: other non-special consumables are used for manufacturing the drainage tube, which wastes medical resources.
Thirdly, the method comprises the following steps: if the traditional drainage tube is of a single hollow pipeline structure, blood enters the drainage tube for coagulation in an operation, and blood clots and necrotic tissues easily block the drainage tube, so that the flushing is not smooth in the treatment after the operation, the drainage is not smooth, and the treatment effect is influenced.
Fourthly: the drainage tube made of non-special consumable materials can not be connected with the flushing syringe in a seamless way, and the efficiency is low during flushing.
