摘要：【中文】本发明涉及一种用于阻生智齿拔除的车针，属于医疗器械领域，解决了现有技术中阻生智齿的快速拔除产生的损伤大、安全性低的问题。本发明的车针分为头部与杆部，头部有用于钻凿牙齿、伸入牙髓腔的钻头和钻刀，钻刀包括多个周向分布的刀片，杆部包括外杆、连接杆和滑动杆，外杆在杆部最外层，起保护作用，连接杆通过螺纹与钻头相连，是整个装置的连接支撑结构，连接杆呈中空结构，其上带有缝隙，内部套有滑动杆，滑动杆相对于连接杆滑动时，外部的滑环可以推动钻刀的刀片向四周水平伸缩，能够切割牙齿并固定在牙齿中，拔除牙齿。本发明实现了损伤小、安全性高的阻生智齿拔除，简化拔除操作，为医生提供便利。 【EN】The invention relates to a car needle for pulling out impacted wisdom teeth, belongs to the field of medical instruments, and solves the problems of large damage and low safety caused by the rapid pulling-out of the impacted wisdom teeth in the prior art. The turning needle is divided into a head part and a rod part, the head part is provided with a drill bit and a drill knife which are used for drilling teeth and extend into a dental pulp cavity, the drill knife comprises a plurality of blades which are distributed circumferentially, the rod part comprises an outer rod, a connecting rod and a sliding rod, the outer rod is arranged on the outermost layer of the rod part and plays a role in protection, the connecting rod is connected with the drill bit through threads and is a connecting and supporting structure of the whole device, the connecting rod is of a hollow structure, gaps are formed in the connecting rod, the sliding rod is sleeved inside the connecting rod, and when the sliding rod slides relative to the connecting rod, an external sliding ring can push the blades of the drill knife to horizontally stretch and retract all. The invention realizes the extraction of the impacted wisdom teeth with small damage and high safety, simplifies the extraction operation and provides convenience for doctors.

摘要：【中文】本发明涉及一种用于正畸托槽的自动化上胶装置，属于医疗器械领域，解决了现有技术中人工托槽上胶医生难以控制托槽上胶量，无法做到完全精确上胶，效率低，容易造成材料的浪费的问题。本发明包括水平电机、水平导轨、水平滑块、竖直电机、竖直滑块和竖直导轨，将需要进行上胶的托槽固定在水平滑块上，水平滑块在水平电机的带动下沿水平导轨滑动，进一步实现托槽在水平方向上移动；上胶器固定在竖直滑块上，竖直滑块在竖直电机的带动下沿竖直导轨移动，上胶器上安装至少一个胶棒，胶棒随竖直滑块在竖直方向上运动，通过调节托槽和胶棒的位置，实现对托槽的精准上胶。本发明实现了对托槽上胶量和上胶位置的精确控制，提高了托槽上胶的效率。 【EN】The invention relates to an automatic gluing device for orthodontic brackets, belongs to the field of medical instruments, and solves the problems that in the prior art, a doctor gluing the artificial brackets is difficult to control the gluing amount of the brackets, cannot realize complete and accurate gluing, is low in efficiency and is easy to cause material waste. The bracket gluing device comprises a horizontal motor, a horizontal guide rail, a horizontal sliding block, a vertical motor, a vertical sliding block and a vertical guide rail, wherein a bracket to be glued is fixed on the horizontal sliding block, and the horizontal sliding block slides along the horizontal guide rail under the driving of the horizontal motor, so that the bracket is further moved in the horizontal direction; the glue applicator is fixed on the vertical sliding block, the vertical sliding block moves along the vertical guide rail under the driving of the vertical motor, at least one glue stick is installed on the glue applicator, the glue stick moves in the vertical direction along with the vertical sliding block, and the accurate gluing of the support groove is realized by adjusting the positions of the support groove and the glue stick. The bracket gluing device realizes the accurate control of the bracket gluing amount and the gluing position, and improves the bracket gluing efficiency.
