Guiding device, expanding device and drainage device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a guiding device, an expanding device and a drainage device.

Background

Oromaxillofacial cervical interstitial infection is a common disease of oromaxillofacial surgery, and due to the fact that the potential fascia interstice is communicated with each other and the characteristics of complex anatomical structures, the infection is deep and is easy to spread to surrounding adjacent tissues, and serious cases can cause a series of serious complications such as respiratory obstruction, sepsis, mediastinitis, septic shock and the like, and even endanger lives. When abscess is formed, the treatment principle is local active drainage, and effective antibiotic treatment is assisted. Clinically, the traditional abscess incision drainage method is proved to be an effective method for ensuring the smoothness of abscess drainage by retaining a drainage substance (a drainage tube or a drainage sheet). However, for deep abscess, there is sometimes difficulty in incising and exploring the pus cavity, and meanwhile, considering the aesthetic requirements of the face and neck, the incision design is often located at the hidden part, often the deep abscess cannot directly enter the pus cavity, the occurrence of complications in the operation is often increased, and the drainage effect is poor. The travel path of the puncture needle can be clearly displayed under the guidance of the B ultrasonic, and can be adjusted at any time, so that the puncture needle directly enters a pus cavity, thereby effectively avoiding important anatomical structures such as blood vessels, being safe and reliable, having no scar residue and having few postoperative complications. The pain of the patient in the whole operation process is small, and the method is particularly suitable for patients with gap infection which have high requirements on beauty, are old and weak or can not endure incision and drainage operations for various reasons. The puncture pus drawing operation under the guidance of B ultrasonic is clinically used, but because the puncture pus drawing operation is performed through too small puncture channel, the drainage hanging can not be conventionally arranged, and no drainage device is used after the puncture pus drawing operation, the current scheme adopted clinically is to repeatedly puncture and draw the pus, so that the pain and the treatment time of a patient are indirectly increased.
