Embodiment 1
[0040] Such as Figure 1 to Figure 3 As shown, the drainage tube for oral and maxillofacial space infection includes a central body, with the insertion end of the central body as the front end, the central body extends along the front and back direction, the central body has a central hole 18, and the rear end of the central body has a connector 17, Connecting head 17 is convenient to be connected with syringe. Among them, the front end of the centrosome is a sealing structure, which prevents the irrigation fluid from washing the pus into the deep healthy tissue and causing the infection to spread.
[0041] In this embodiment, the central body is provided with supporting wings 16, and four supporting wings 16 are arranged at intervals along the circumferential direction of the central body, and drainage grooves 14 are formed between adjacent two supporting wings 16, and the drainage grooves 14 supply pus and The flushing liquid flows out; the front part of the bottom of the d...
Embodiment 2
[0051] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the support wing 16 includes two support sections, which are respectively the front support section 12 and the rear support section 15, and the front support section 12 and the rear support section 15 are spaced apart along the front-rear direction. Arranged, the radial dimension of the front support section 12 is smaller than the radial dimension of the rear support section 15 . In this example, if Figure 4 As shown, the drainage tube includes a central body 24, four support wings 23 are arranged on the central body 24, a drainage groove 22 is formed between two adjacent support wings 23, and a communication hole 21 is provided at the front of the bottom of the drainage groove 22; The tail end of central body 24 has connector 25, and connector 25 is used for connecting syringe, and central body 24 also has central hole 26, and central hole 26 communicates with drainage groove 22 through c...
Embodiment 3
[0053] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the radial dimensions of the front support section 12 and the rear support section 15 gradually increase from front to back. In this embodiment, the radial dimension of the front support segment is consistent from front to rear, and the radial dimension of the rear support segment is consistent from front to rear.
