The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3.Anti-skidding two sharp highmore antrum puncture needle is made up of nook closing member 1, inner sleeve 3 and trocar sheath 4, and boss 2 is arranged on the nook closing member 1, and locating slot 7 is arranged on the inner sleeve 3, nook closing member 1 is through in the inner sleeve 3, boss 2 is installed on the locating slot 7, and trocar sheath 4 is sleeved on the inner sleeve 3, and there is anti-slop serrations 6 lower end of trocar sheath 4.The end of nook closing member bar 8, inner sleeve 3 has crosspointer point 9,5.The puncture antral device is on the basis of former antrum puncture needle, increases a trocar sheath 4, and anti-slop serrations 6 is arranged on the end of trocar sheath 4; when being expert at puncture, trocar sheath 4 can move up and down, and moves up; the energy controlling depth moves down and can protect the crosspointer point not stab turbinate mucosa.When anti-slop serrations 6 can be realized the row puncture, be difficult for the purpose of slippage displacement.Crosspointer point 9,5 is all arranged on its nook closing member bar 8 and the inner sleeve 3.Its effect is can rotate into the hole chamber when penetrating the maxillary sinus antetheca, does not promptly damage turbinate mucosa, can control the depth, not slippage again, be difficult for the damaged bone wall.Shown in Fig. 1,2,3,4,5,6.During use, hand-held nook closing member 1 inserts nook closing member bar 8 in the inner sleeve 3, and the boss 2 on the nook closing member 1 is installed in the locating slot 7, then trocar sheath 4 is sleeved on the inner sleeve 3.To patient row puncture antral the time, antrum puncture needle is put into normal puncture antral position, the anti-slop serrations 6 on the trocar sheath 4 is fixed on the puncture position face, prevented puncture needle slippage displacement, malleable puncture position has not guaranteed therapeutic effect like this.The hands of keeping right then firmly promotes nook closing member 1 forward, rotates nook closing member 1 simultaneously, when treating that crosspointer point 5, inner sleeve 3 enter hole chamber to trocar sheath 4 places, extracts nook closing member 1, can carry out conventionally maxillary sinusitis flushing, reach drug-injection in treatment.
