AI Technical Summary

Technical Problem

[0003]由于导板内的导环与钻针之间的间隙较小，导致冷凝水无法穿过导板对钻头进行冷却，没有冷却的在钻头在切削的过程中刃部积累大量热量从而导致骨灼伤，影响种植体表面与骨组织的结合，降低手术成功概率

Benefits of technology

1.钻身主体用于钻孔，在使用的过程中，导向体与种植导板内的导环配合，从而对钻头进行导向，冷凝水可以通过导向体外周面的导水槽引导，从而进入到种植窝内，对钻孔处进行冷却，防止钻头在切削的过程中，钻体产生大量的热量导致骨灼伤，将导水槽设计成螺旋状，在钻头旋转的过程中，根据阿基米德螺旋效应，导水槽面向钻体旋转方向的内壁面对冷凝液施加沿重力方向的压力，使冷凝液加速流动，由于位于底部的冷凝液的流速更大，根据伯努利效应，流速较大处压强较小，导水槽的下方会产生负压，会进一步引导上部的上方的流体，加速流体的流动。

Abstract

The application relates to the field of dental surgical instruments, in particular to a guide plate guiding type tooth implantation drill bit which comprises a drill body and a guide body, the drill body comprises a tool shank, a neck and a drill body, the tool shank and the drill body are located at two ends of the neck, the tool shank and the neck are in the form of rods, the guide body is in the form of a cylinder and is located at the neck, a plurality of water guide grooves are distributed in a circular array on the outer circumferential surface of the guide body with the central axis of the guide body as a rotation axis, each water guide groove starts from one end of the guide body close to the drill body and extends in a spiral shape along the rotation direction of the drill body. Through the design of the spiral water guide grooves, the Archimedes spiral effect and the Bernoulli effect are utilized to effectively guide the condensate water to flow into the implantation nest, the cooling of the drilled hole is realized, bone burn is prevented, and the cooling efficiency and the surgical safety are improved.
