Detailed Description

The following describes in detail the embodiments of the present utility model with reference to the drawings.

Examples: referring to fig. 1-2, an off-oral scanning target attachment tool includes an outer housing including a grip portion, a shaft portion, and a working portion. The holding part is used for holding; the diameter of the rod part is smaller than that of the holding part and is used for extending into the oral cavity of a patient; the working part is arranged at the end part of the rod part, and one side of the working part is opened.

A target mounting sleeve 13 is connected to the working portion and is used to fit over the implant positioning target 16 when the implant positioning target 16 is assembled and disassembled, so as to fix the implant positioning target 16.

The shape of target installation sleeve 13 is the rectangle frame form with implant location target 16 shape adaptation, be equipped with rubber snap ring 14 on the target installation sleeve 13 inner wall, target installation sleeve 13 inner wall is equipped with the recess, rubber snap ring 14 is embedded in this recess. The rubber snap ring 14 is arranged to enable the implant positioning target 16 to be difficult to separate due to friction force when placed on the target mounting sleeve 13, and plays a role in flexible fixation, so that the implant positioning target 16 is easy to be placed in or taken away from the oral cavity of a patient through the target mounting sleeve 13. In addition, the inner length and width of the target mounting sleeve 13 is larger than that of the target, a gap is usually reserved between the target mounting sleeve 13 and the implant positioning target 16, and the arranged rubber clamping ring 14 also plays a certain role in centering.
