Fig. 2 is the enlarged drawing of a-quadrant in Fig. 1 of this utility model antrum puncture needle;
Fig. 3 is the sectional view of this utility model antrum puncture needle.
Detailed description of the invention
As shown in Figures 1 to 3, this utility model antrum puncture needle, comprises outer pin 1 and interior pin 2.
This outer pin 1 comprises needle guard 11 and needle tubing 12, wherein, this rounded sleeve-like structure in needle guard 11 one end, the tapered structure of the other end, internal run-through is provided with perforation 13; This perforation 13 is made up of one section of cylindricality perforation 131 and one section of cone-type piercer 132, and this section of cylindricality perforation 131 is positioned at the entrance point of needle guard 11, and this section of cone-type piercer 132 is positioned at the port of export of needle guard 11; Meanwhile, this needle guard 11 entrance point side offers stopper slot 111, and the relative lateral symmetry that this needle guard 11 is being positioned at middle part outer wall is provided with pair of push rods 14.This needle tubing 12 connects as one with needle guard 11, is specifically connected to the end, one end that this needle guard 11 is tapered.
It is inner that this interior pin 2 coupling is arranged in this outer pin 1, it comprises needle handle 21 and needle body 22, and wherein, this needle handle 21 1 end is provided with handle chassis 211, the other end is circular cone structure and side is convexly equipped with limited post 212, and this limited post 212 matches with the stopper slot 111 of the needle guard 11 of this outer pin 1.This needle body 22 is solid needle body structure, and it is connected in the middle part of the frustum of a cone end face of this needle handle 21, and the pore of the needle tubing 12 of the diameter of this needle body 22 and this outer pin 1 matches; After this interior pin 2 penetrates this outer pin 1 inside, this needle handle 21 one end in circular cone structure penetrates in one section of cylindricality perforation 131 of this outer pin 1, in the needle tubing 12 that this needle body 22 coupling is arranged in this outer pin 1 and needle point keeps concordant with the needle point of the needle tubing 12 of outer pin 1; Simultaneously, this needle body 22 tip also in be provided with miniature position sensor 23, this miniature position sensor 23 is connected by the signal of telecommunication with external computer, the position at this miniature position sensor 23 place is the position of needle point place patient's maxillary sinus of puncture needle, after puncture needle penetrates patient's maxillary sinus, by the run trace of the miniature position sensor 23 of computer Real-Time Monitoring, judge that the needle point of puncture needle is positioned at the position of patient's maxillary sinus.
