Detailed Description
Example 1
As shown in figures 1 and 2, a pincer-shaped vertical tooth extraction dilator comprises two paired handles 1 and two forceps bodies corresponding to the handles 1, wherein the front ends of the two handles are oppositely provided with hinged bosses 11, the two handles 1 are hinged to form a handheld part, the forceps bodies are positioned on the front side of the handheld part and comprise prying plate parts 21 and connecting parts 22, each connecting part 22 is an arc-shaped part, the rear end of each arc-shaped part is integrally connected with the front end of the handle 1, each prying plate part 21 is an elongated flat plate with a long edge of 30mm, a width of 10mm and a thickness of 2mm, a plane perpendicular to the handheld part is provided with three parallel clamping grooves 31 on the long edge of one side of the elongated plate, each prying plate part 21 is positioned on the outer arc side of the connecting part 22, the depth of each clamping groove is from the edge of the prying plate part to the width of the elongated flat plate 1/2 for placing a screw tap, the long edge of the other side is fixedly connected with the front part of the connecting part, can not cause the injury to patient's perioral mucosa, also reduced the influence of lip of the mouth to executing the art person simultaneously, when sled board portion perpendicular to handheld portion can make the operator just in time hold handheld portion, sled board portion just in time keeps flat in patient's tooth top surface.
