The present invention will be further described with reference to the following examples.
Referring to fig. 1 to 5, the present invention discloses a multifunctional STOP device, which includes a STOP body 1, a plastic screw 2 and a double-ended wrench 3.
The STOP body 1 is in a rectangular parallelepiped shape, has a length H1 of 2.7mm, a width H2 of 2.0mm, and a height H3 of 2.0mm, and is small in size, round in shape, free from obstruction of oral cavity functions, and small in foreign body sensation. The STOP body 1 is provided with a plastic screw groove 103, and the inner diameter of the plastic screw groove 103 is 1.0mm and the length is 1.5 mm. The plastic screw groove 103 is provided with concave screw threads which are matched with the plastic screws 2. The two are tightly combined through the screw thread, so that the deformation and looseness after external force is prevented. The nitinol archwire slot 102 runs through two opposing sides of the STOP body 1 perpendicular to the plastic screw slot 103. The plastic screw groove 103 is communicated with the nickel-titanium arch wire groove 102, and the plastic screw 2 is allowed to enter the nickel-titanium arch wire groove 102 after being screwed down, so that an orthodontic nickel-titanium arch wire can be clamped conveniently, and the STOP main body 1 and the nickel-titanium arch wire are prevented from sliding mutually. A nickel-titanium arch wire groove pipe wall 101 is formed between the nickel-titanium arch wire groove 102 and the STOP main body 3, the thickness of the nickel-titanium arch wire groove pipe wall 101 is 0.5mm, which is larger than the minimum distance between the nickel-titanium arch wire and the buccal labial surface of the tooth, and the deformation of the arch wire can not be caused after the nickel-titanium arch wire is brought in. The height H4 of the nickel-titanium arch wire groove 102 is 1.0mm, the width H5 is 0.7mm, the space is sufficient, and the nickel-titanium arch wire of different types can enter. The use can be different according to the front and back teeth. For the anterior tooth area, the plastic screw groove 103 can be opened in the labial direction, which is beneficial to the direct rotation stress application of the straight head 302; for the back tooth area, the plastic screw groove 103 can be opened in a fitting manner, so that the horizontal rotation of the elbow 303 is facilitated, and the foreign body sensation can be reduced. STOP main part 1 is stainless steel metal material, can resist its deformation after the atress.
The plastic screw 2 includes a thread 201 and a triangular prism coupler 202, and the thread 201 has a diameter of 1mm and a length of 1 mm. The thread 201 of the plastic screw 2 is of an outward convex type. The screw 2 is made of hard plastic and has certain strength, so that the screw can resist deformation after being stressed and can increase the friction force between the screw and the STOP main body 1 to prevent the screw from sliding. The triangular prism joint 202 is a regular triangular prism, each angle of the triangle of the cross section is a round arc, and the diameter of the circle where the round arc is located is 0.6 mm.
The double-ended wrench 3 includes a double-ended wrench main body 301, a straight head 302, and an elbow 303. The length H6 of the double-ended wrench body 301 is 90mm, and the straight head 302 and the elbow 303 are respectively arranged at two ends of the wrench body 301. The head appearance of straight head 302 and elbow 303 is cylindrical, and the external diameter is 1.0mm, and inside is that blunt regular triangular prism is sunken, and the diameter of the circle at blunt arcuation place is 0.6mm, the straight head 302 and the thinnest department of elbow 303 of double-end wrench 3 are 0.2mm, and the appearance is the circular arc type, can be better resist the revolving force and do not warp, connect 202 phase-matchs with triangular prism, carry out mechanical gomphosis through unsmooth blunt triangular prism of circle, both can resist deformation after the atress, can conveniently rotate the afterburning again. The shape of the middle part of the double-end wrench main body 301 is a regular hexagonal prism shape, and the distance from the central point of the bottom surface of the prism to the side edge is 6mm, so that the resistance can be increased, and the rotating force application is facilitated. The cross section of the part of the double-end wrench main body 301, which is connected with the straight head 302 and the elbow 303, is a regular hexagon, the distance from the central point of the regular hexagon to the vertex is 1mm, the shape moving length H7 of the double-end wrench main body and the straight head is 10mm, the length is proper, the double-end wrench main body is convenient to hold, and the force is directly applied to the lip and cheek side. The double-ended wrench body 301 is moderate in size and convenient to hold. The cylinder length of straight head 302 is 1mm, is regular hexagonal prism around the right angle corner of elbow 303, and the distance of the central point of prismatic bottom surface to the side edge is 1mm, and the corner moves backward and forms cylindrically, and length is suitable, both can dodge the interference of adjacent tooth, and touching is favorable to the level to afterburning to jaw tooth when can avoiding afterburning again. The straight head 302 and the elbow 303 of the double-ended wrench 3 are applied to the anterior and posterior tooth zones, respectively. The double-ended wrench 3 is used by front and rear teeth because the operation space in the oral cavity is limited. For the anterior teeth area, the operation space is relatively large, and the straight head 302 can be applied with force by rotation; for the posterior teeth area, the cheek tongue and the teeth block, the operation space is relatively small, and the elbow 303 is applied, and the limited space is utilized to horizontally rotate and apply force through the corner.
