Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation
Book text can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
Fig. 1 ~ 5 show the disposable brachytherapy interpolation needle of the utility model, including interpolation needle ontology 1, needle
Core 2:
Cavity is equipped in the interpolation needle ontology 1, front end is equipped with closed needle point 3；The needle core 2, which is detachably located at, to be inserted
It is worth in 1 cavity of needle ontology, front end is located at needle point 3；Connecting cylinder 4, connecting cylinder 4 are arranged with outside 1 tail portion of interpolation needle ontology
Including from rear to preceding sequentially connected hickey 41, hand-held part 42, hand-held part 42 and 41 junction of hickey be provided with to
Outer boss 43 outstanding；
2 tail end of needle core is fixed in a fixing head 5, and fixing head 5 front end coaxial with needle core 2 is provided with and hickey
The fixation hole 6 that 41 shapes match is equipped with and the matched interior spiral shell of hickey 41 with coaxial 6 inner wall of the fixation hole of needle core 2
Line.
In this technical solution, needle core 2 is placed in 1 cavity of interpolation needle ontology, hickey 41 is linked in fixation hole 6
It is interior, be tightened first 5 make 6 inner wall of fixation hole and 41 outer wall of hickey cooperate sting it is tight, boss 43 against 5 front end of fixing head,
To avoid interpolation needle from occurring stuck in implantation process since external force fixing head 5 moves forward；It is convenient for hand-held part 42
Medical staff holds interpolation needle and implements tissue insertion, improves implantation efficiency, 3 end of needle point of 1 front end of interpolation needle ontology is conducive to group
Insertion is knitted, 3 front end portion of needle point is solid construction, and needle point 3 reduces tissue damage and optimization easily implantation to the maximum extent；When slotting
