Detailed Description
Referring to fig. 3, for the utility model discloses an orthodontic ligature circle placer, including first clamp arm 2 and second clamp arm 3, first clamp arm 2 is connected with second clamp arm 3's one end, and the other end separates gradually and opens, and the bottom branch of first clamp arm 2 is formed with first clamping part 22 and second clamping part 23, and is relative, and the bottom branch of second clamp arm 3 is formed with third clamping part 32 and fourth clamping part 33, and first clamping part 22 sets up along opening the direction with third clamping part 32 relatively, and second clamping part 23 sets up along opening the direction with fourth clamping part 33 relatively.
In a natural state, a gap is reserved between the first clamping arm 2 and the second clamping arm 3, when the clamping device is used, the first clamping arm 2 and the second clamping arm 3 are held by hands, pressure is applied to the first clamping arm 2 and the second clamping arm 3 by fingers, the first clamping arm 2 is attached to the second clamping arm 3, the first clamping portion 22 is folded with the third clamping portion 32, the second clamping portion 23 is folded with the fourth clamping portion 33, the fingers are loosened, and the first clamping arm 2 and the third clamping arm prop the ligature ring 6 open and clamp the ligature ring 6 under the action of elastic restoring force.
Referring to fig. 3, specifically, one side of the second clamping portion 23, which is far away from the first clamping portion 22, and one side of the fourth clamping portion 33, which is far away from the third clamping portion 32, are provided with a limiting groove 5, specifically, the limiting groove 5 is transversely formed along the second clamping portion 23 and the fourth clamping portion 33, when the ligature ring 6 is pulled outwards and downwards, the ligature ring 6 is clamped in the limiting groove 5 and moves together with the second clamping portion 23 and the fourth clamping portion 33, and the phenomenon that the ligature ring 6 slips due to lack of effective limitation in the pulling process is avoided.
Referring to fig. 4 and 5, further, the forceps heads 4 of the first clamping portion 22, the second clamping portion 23, the third clamping portion 32 and the fourth clamping portion 33 are rounded to avoid that the forceps heads 4 are too sharp to hurt the inner wall of the oral cavity in the using process.
In a natural state, the distance between the forceps head 4 of the first clamping part 22 and the forceps head 4 of the second clamping part 23 is larger than the diameter of the inner ring of the ligature ring 6 in a natural state, so that the first clamping part 22 is attached to the third clamping part 32, the second clamping part 23 is attached to the fourth clamping part 33 and can be simultaneously inserted into the inner ring of the ligature ring 6, the ligature ring 6 is propped open and clamped when the first clamping arm 2 is separated from the second clamping arm 3, the propped ligature ring 6 is rectangular, the ligature ring 6 is moved to the bracket body 11 on the surface of a tooth, the arm is moved upwards and inwards, the ligature ring 6 is sleeved on the two bracket wings 14 above the groove 13 along the A direction, then the arm is moved outwards and downwards, so that the ligature ring 6 between the second clamping part 23 and the fourth clamping part 33 is pulled to the lower part of the groove 13, the ligature ring 6 is clamped on the bracket wing support 15 from the lower part of the groove 13 along the B direction, thus, the whole ligature ring 6 is sleeved on the bracket body 11, so that the arch wire is fixed in the groove 13.
Referring to fig. 4, since the ligature ring 6 is a rubber ring, the outer sides of the second clamping portion 23 and the fourth clamping portion 33 easily wear the ligature ring 6 in the process of pulling the ligature ring 6, therefore, the outer sides of the second clamping portion 23 and the fourth clamping portion 33 protrude outwards to form a smooth arc surface, when the ligature ring 6 is pulled towards the lower part of the groove 13, a slight outward downward force is required, and the outer sides of the second clamping portion 23 and the fourth clamping portion 33 can slide along the ligature ring 6 through the smooth arc surface.
After the ligature ring 6 is completely sleeved, the first clamping arm 2 and the second clamping arm 3 are moved upwards and outwards, so that the ligature ring 6 between the second clamping part 23 and the fourth clamping part 33 is separated from the limiting groove 5, at the moment, the ligature ring 6 between the first clamping part 22 and the third clamping part 32 is separated from the second clamping part 23 and the fourth clamping part 33, and the first clamping arm 2 and the second clamping arm 3 can be directly moved out.
Referring to fig. 3, when the ligature ring 6 is accidentally fallen, a wearer needs to find the position of the bracket 1 by means of a mirror, so that the ligature ring 6 is conveniently sleeved on the bracket 1, a first bending portion 21 is arranged at one end of the first clamping arm 2, a second bending portion 31 is arranged at one end of the second clamping arm 3, the first clamping portion 22 and the second clamping portion are formed by bifurcating from one end of the first bending portion 21, the third clamping portion 32 and the fourth clamping portion 33 are formed by bifurcating from one end of the second bending portion 31, the phenomenon that the ligature ring 6 is worn is avoided, the sight of the wearer is shielded by the hand of the wearer, the position of the bracket 1 cannot be observed by the wearer from the mirror, and the ligature ring 6 is inconvenient to wear by the wearer.
Referring to fig. 3, the outer sides of the first clamping arm 2 and the second clamping arm 3 are provided with anti-slip patterns 7, and the anti-slip patterns 7 can increase friction force, so that a wearer can better grip the first clamping arm 2 and the second clamping arm 3, accidental sliding in the wearing process is avoided, and the forceps head 4 pricks the inner wall of the wound cavity.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
