一种牙髓腔糊剂填充器
摘要：
本发明公开了一种牙髓腔糊剂填充器，包括注射器以及填充针，填充针包括定位套针和注射针，所述定位套针和注射针的底部分别安装有定位套针针座和注射针针座，定位套针与定位套针针座内部相通，注射针与注射针针座内部相通，所述定位套针的头端设有三棱针头；定位套针的头端外壁上设有糊剂出口，注射针活动插入定位套针内，所述注射针针座的头端位置安装有密封塞，本发明结构合理，使用方便，利用密封塞堵住定位套针针座与注射针针座之间的连接缝隙，从而避免出现糊剂流出的情况，通过旋转限位套，使得限位套在螺纹管上线性移动，这样便可调节限位套的限位效果，这样便可实现精确的插入深度控制。
摘要（英）：

The invention discloses a dental pulp cavity paste filling apparatus which comprises an injection syringe and a filling needle. The filling needle comprises a positioning trocar and an injection needle, a positioning trocar bed and an injection needle bed are mounted at the bottom of the positioning trocar and the bottom of the injection needle, the positioning trocar is communicated with the inside of the positioning trocar bed, the injection needle is communicated with the inside of the injection needle bed, and a three-edged needle head is arranged at the head end of the positioning trocar; paste outlets are formed in the outer wall of the head end of the positioning trocar, the injection needle is movably inserted into the positioning trocar, and a sealing plug is mounted at the head end of the injection needle bed. The dental pulp cavity paste filling apparatus has the advantages that the dental pulp cavity paste filling apparatus is reasonable in structure and convenient to use; connection gaps between the positioning trocar bed and the injection needle bed can be plugged by the sealing plug, and accordingly paste can be prevented from flowing out; a limit sleeve can rotate and can linearly move on a threaded tube, accordingly, limit effects of the limit sleeve can be adjusted, and the insertion depths can be accurately controlled.
