Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
The embodiment of the utility model basically provides a minimally invasive tooth extraction needle as shown in fig. 1-2, which comprises a working section 2 and a clamping section 1, wherein the working section 2 and the clamping section 1 are integrally formed, and the clamping section 1 and the working section 2 are in smooth transition;
as shown in fig. 2, the working section 2 is conical and is a split drill 3, the tip of the working section 2 is hemispherical, the surface of the tip is covered with silicon carbide 4, and the radius of the hemispherical tip of the working section 2 is 5mm.
As shown in the figure 1, the side wall of the clamping section 1 is provided with a marking area, the marking area comprises 4 marking positions, 3MM distances are reserved between different marking positions, marking points 5 are arranged in the 4 marking positions, the distances between the marking points 5 in the 4 marking positions and the working section 2 are respectively 7MM, 10MM, 13MM and 16MM, and the number of the marking points 5 in the 4 marking positions is respectively 1, 2, 3 and 4.
The detailed working principle process of the embodiment is as follows:
