Description

Safe glaze removing tool Technical Field The utility model relates to the technical field of oral medical instruments, in particular to a safe stripping tool. Background Adjacent surface stripping, also known as "slicing", is a technique commonly used in dental appliances to abrade a quantity of enamel from the adjacent surface of a tooth using appropriate equipment to reduce the width between the near and far teeth and provide a quantity of clearance for crowding teeth to reduce the likelihood of tooth extraction. When the adjacent surface glaze removal is implemented in the correction process, the glaze removal amount and the position must be well grasped, and the damage to the shape and the structure of the teeth is prevented. In clinical work, the stripping is carried out by matching with a sand strip stripping tool, so that a safer stripping mode is adopted. The prior adjacent surface glaze removing device structure is shown in figure 1, and comprises a first retainer 1 and a second retainer 2, wherein a connecting strip 11 is fixed at the top of the first retainer 1, a connecting groove is formed at the top of the second retainer 2, the connecting strip 11 is slidably inserted into the connecting groove to form an arched retainer by the first retainer 1 and the second retainer 2, a stud 3 is fixedly connected to the inner side of the second retainer 2, a knob 4 is connected to the stud 3 in a threaded manner, the knob 4 can rotate on the stud 3 to abut against the first retainer 1, a first clamping groove is formed in the bottom of the first retainer 1, a second clamping groove is formed in the bottom of the second retainer 2, sand strips 5 are clamped in the first clamping groove and the second clamping groove, a first clamping sleeve 6 is hinged to a frame body of the first retainer 1, the first clamping sleeve 6 is suitable for clamping one end of the sand strips 5 positioned at the bottom of the first retainer 1, a second clamping sleeve 7 is hinged to a frame body of the second retainer 2, and the second clamping sleeve 7 is suitable for clamping the other end of the sand strips 5 positioned at the bottom of the second retainer 2. When the novel tooth enamel remover is used, the knob 4 is firstly rotated on the stud 3 to be in contact with the first retention frame 1 so as to tightly tighten the sand strips 5 clamped in the first clamping groove and the second clamping groove, then the whole adjacent surface enamel remover is tightly pressed by hands, then the sand strips 5 are pressed into tooth gaps and then repeatedly moved, a certain amount of enamel is ground off on the adjacent surface of the tooth through the sand strips 5, and the grinding amount needs to be accurately controlled so as to avoid overlarge damage to the tooth. The inventor of the present application has found that, in clinical practice, when the adjacent surface is stripped by the sand strip 5, in most cases, the sand strip 5 is difficult to avoid touching the edge of the gingival papilla, causing bleeding during stripping and causing a certain damage to the patient. Disclosure of utility model Aiming at the technical problems that when the prior adjacent surface glaze removing device carries out adjacent surface glaze removing through a sand strip, the sand strip is difficult to avoid touching the edge of a gingival papilla and bleeding is caused during glaze removing under most conditions, the utility model provides a safe glaze removing tool. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a safe glaze instrument that removes, includes first retainer and second retainer, the connecting strip is fixed with at the top of first retainer, the spread groove has been seted up at the top of second retainer, the connecting strip slidable grafting becomes an arch-shaped retainer with first retainer and second retainer in the spread groove, the inboard fixedly connected with double-screw bolt of second retainer, threaded connection has the knob on the double-screw bolt, the knob can rotate to contradicting with first retainer on the double-screw bolt, the bottom of first retainer is equipped with first draw-in groove, the bottom of second retainer is equipped with the second draw-in groove, first draw-in groove and second draw-in groove inside callipers are equipped with the sand strip, the first clamp cover that articulates on the support body of first retainer, first clamp cover is suitable for pressing from both sides the sand strip one end that is located first retainer bottom, the second clamp cover is suitable for pressing from both sides with the sand strip one end that is located second retainer bottom, the second clamp cover top contact with the montant is suitable for pressing from both sides the top of the top, the top of the montant is suitable for pressing from both sides the cover, the top of the montant is suitable for contacting.
