Description

Technical Field

[0001] The utility model relates to the field of dental instruments, in particular to a positioning device for tooth treatment. Background Art

[0002] The straight wire appliance technique is a commonly used technique in orthodontic treatment. The accurate positioning of brackets and buccal tubes is very important, which directly determines whether precise control of the three-dimensional direction of teeth can be achieved. Since brackets and buccal tubes are small in volume and the operating space in the patient's oral cavity is limited, the traditional method of directly bonding brackets and buccal tubes has the problems of cumbersome operation and inaccurate positioning, and this problem is particularly prominent during the bonding process of buccal tubes.

[0003] At present, the tools used by doctors in clinical orthodontic operations are still ordinary dental forceps. Doctors mainly rely on experience to paste brackets and buccal tubes on the tooth surface. Due to the long clinical operation time, doctors' vision is prone to fatigue, and the quality of pasting brackets and buccal tubes often cannot be satisfactory. The adhesive is very likely to block their bayonets, resulting in the wire arch not passing smoothly. Especially when pasting buccal tubes, the existing method is to first block the position where the buccal tube is connected to the wire arch with solid wax. During the bonding process, the solid wax can prevent the glue from entering the connection between the buccal tube and the wire arch. After the buccal tube is pasted and the solid wax is removed, the connection between the wire arch and the buccal tube is carried out. Therefore, the operation is very troublesome.

[0004] The patent document with the publication number CN216797867U discloses a pair of forceps for buccal tubes with high stability. When in use, first place two groups of clamping secondary rods on both sides of the buccal tube, and then press the clamping main rod, so that the clamping main rod drives the clamping secondary rods to move, so that the clamping secondary rods drive the snap ring to move, so that the snap ring drives the telescopic rod to clamp both sides of the buccal tube, and the snap ring is inserted into the holes on both sides of the buccal tube, so that the clamping secondary rods clamp the buccal tube. At the same time, the telescopic rod is tightly attached to the inner walls of the holes on both sides of the buccal tube, so that the telescopic rod contracts inward, and the telescopic rod drives the limiting plate to move inside the snap ring, and the limiting plate compresses the spring. Under the elastic action of the spring, the spring always pushes the limiting plate to move outward, so that the limiting plate pushes the telescopic rod to move. And under the limitation of the limiting ring, the moving distance of the telescopic rod is limited, so that one end of the telescopic rod is always tightly attached to the inner walls of the holes on both sides of the buccal tube, so that the clamping secondary rods clamp the buccal tube more stably. However, during the bonding process of the buccal tube, when the glue enters the side holes of the buccal tube, the glue easily causes the snap ring to bond with the buccal tube, which is not convenient for the separation of the snap ring and the buccal tube.

[0005] The patent document disclosed as CN218247433U discloses an orthodontic bonding retention carrier. When pasting the buccal tube, the bracket or buccal tube is placed in the card slot 6 of the clamp head 5. At this time, the bonding surface of the bracket or buccal tube and the tooth faces outward, and the part where the bracket or buccal tube is connected to the arch wire is located in the card slot. Under the friction between the clamp head and the bracket or buccal tube, the bracket or buccal tube can be prevented from falling out of the card slot. During the bonding process, the glue can be prevented from entering the part where the bracket or buccal tube is connected to the arch wire. Then, the main body is held so that the push plate is located in the palm of the hand, so that the middle finger and index finger support the main body, and the thumb Press on the arc surface and place the index finger between the arc surface and the fixing ring, move the carrier, stick the bracket or buccal tube on the tooth, then use the thumb to press the bracket or buccal tube against the tooth for a certain period of time through the main body and the clamp. When the glue solidifies, use the palm of the hand to push the push plate and the push rod into the main body. During the movement of the push rod into the main body, the hard elastic part moves into the clamping groove. When the hard elastic part contacts the bracket or buccal tube, the hard elastic part keeps the bracket or buccal tube in a state of being tightly pressed against the tooth, and the main body and the clamp are separated from the bracket or buccal tube, so that the bracket or buccal tube is stably and accurately stuck on the tooth. The carrier can prevent glue from entering the part where the bracket or the buccal tube is connected to the archwire. However, when separating the buccal tube from the carrier, it is necessary to use the palm of the hand to push the push plate and the push rod to move into the main body. In order to ensure the firmness of the buccal tube bonding, the stability of the main body also needs to be ensured. The direction in which the push plate and the push rod move into the main body is not perpendicular to the buccal tube, so it is not easy to maintain the stability of the main body. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a positioning device for tooth treatment which can prevent glue from entering the connection between the buccal tube and the archwire during the bonding process and can facilitate the separation of the buccal tube from the archwire.

[0007] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0008] A positioning device for tooth treatment comprises a handlebar, the upper end of which is connected to an upper block, one end of which is connected to a clamping head, a slot is formed on the clamping head, a rubber sleeve is fixed in the slot, a push plate is slidably and sealably connected in the rubber sleeve, the push plate is slidably connected to the upper block, an opening is formed on the upper block and is connected to the slot on the clamping head, a lever is rotatably arranged in the opening, the lever passes through the opening, one end of the lever is tightly against the push plate, the other end of the lever extends to the outside of the upper block, and the end of the lever in contact with the push plate is tilted upward.

[0009] Specifically, the end surface of the upper block away from the clamping head is a curved surface, and the end surface of the upper block away from the clamping head is processed with anti-slip grooves.

[0010] Specifically, the shifting rod is rotatably connected to the upper block via a pin, and the pin is located in the opening.

[0011] Specifically, optical rods are fixed on both the upper and lower sides of the push plate towards one end of the upper block. The axial direction of the optical rod is parallel to the movement direction of the push plate. Blind holes corresponding to the optical rods are provided on the upper block, and the optical rods are slidably and sealingly inserted into the blind holes.

[0012] Specifically, the handle rod, the chuck and the upper block are integrally formed, and the handle rod, the upper block and the chuck are all made of high molecular polypropylene material.

[0013] Specifically, the handle rod, the upper block and the chuck are detachably and fixedly connected, and the handle rod, the upper block and the chuck are all made of stainless steel.

[0014] Specifically, the handle rod is threadedly connected to the upper block, and the chuck is snap-connected to the upper block.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. When bonding the buccal tube or bracket, the part where the buccal tube or bracket is connected to the arch wire is located inside the rubber sleeve, and the reticulated plate of the buccal tube or bracket is located outside the chuck, which can effectively prevent the adhesive from entering the part where the buccal tube or bracket is connected to the arch wire, and prevent the connection between the arch wire and the bracket or buccal tube from being affected after the adhesive solidifies.

[0017] 2. During the process of bonding the reticulated plate of the buccal tube or bracket to the patient's teeth with glue, the thumb of the medical staff tightly abuts against the upper block, and the upper block makes the reticulated plate of the bracket or buccal tube tightly abut against the patient's teeth through the chuck, which can ensure the firm bonding of the bracket or buccal tube to the patient's teeth.

[0018] 3. After the bracket or buccal tube is bonded to the patient's teeth, the medical staff uses the thumb to push the lever to rotate. When the lever rotates, the push plate slides and can push the bracket or buccal tube away from the patient's teeth and the bracket or buccal tube bonded to the patient's teeth. The movement direction of the push plate is perpendicular to the bracket or buccal tube bonded to the patient's teeth. Therefore, when the lever rotates, the direction in which the device moves away from the patient's teeth is perpendicular to the bracket or buccal tube, ensuring the firm bonding performance of the bracket or buccal tube to the patient's teeth when the device is separated from the bracket or buccal tube.

[0019] 4. When bonding the bracket or buccal tube, the part where the bracket or buccal tube is connected to the arch wire is stably located in the slot hole of the chuck, which can effectively prevent the bracket or buccal tube from falling off, facilitate the positioning of the bracket or buccal tube, and improve the efficiency and quality of the paste of the bracket or buccal tube.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1: Reference Figures 1 - 4 As shown, a positioning device for tooth treatment includes a handlebar 1, the upper end of the handlebar 1 is connected to an upper block 2, one end of the upper block 2 is connected to a clamp 3, a slot is formed on the clamp 3, and a rubber sleeve 5 is fixed in the slot.

[0027] A push plate 4 is slidably and sealably connected inside the rubber sleeve 5, and the push plate 4 is slidably connected to the upper block 2. Specifically, a polished rod 9 is fixed to both upper and lower sides of the push plate 4 facing one end of the upper block 2, and the axial direction of the polished rod 9 is parallel to the movement direction of the push plate 4. A blind hole 10 corresponding to the polished rod 9 is opened on the upper block 2, and the polished rod 9 is inserted in the blind hole 10 in a slidable and sealable manner.

[0028] The upper block 2 is provided with an opening 8 connected to the slot on the clamping head 3, and a lever 6 is rotatably arranged in the opening 8. Specifically, the lever 6 is rotatably connected to the upper block 2 via a pin 7, and the pin 7 is located in the opening 8. The lever 6 passes through the opening 8, one end of the lever 6 is tightly against the push plate 4, and the other end of the lever 6 extends to the outside of the upper block 2, and the end of the lever 6 in contact with the push plate 4 is tilted upward.

[0029] The end surface of the upper block 2 away from the clamping head 3 is a curved surface, and the end surface of the upper block 2 away from the clamping head 3 is processed with anti-slip grooves.

[0030] Before the buccal tube or bracket is bonded, the part where the buccal tube or bracket is connected to the archwire is located in the rubber sleeve 5. At the same time, the clamp head 3 is pressed against the patterned plate of the bracket or buccal tube. Then, glue is applied on the patient's teeth and the patterned plate of the bracket or buccal tube, and the medical staff holds the handle 1 and then uses the device to fix and bond the bracket or buccal tube to a fixed position on the patient's teeth. In the process of bonding the buccal tube or bracket, the glue can be effectively prevented from entering the part where the buccal tube or bracket is connected to the archwire, so as to prevent the glue from affecting the connection between the archwire and the bracket or buccal tube after curing.

[0031] When bonding the bracket or buccal tube, the part where the bracket or buccal tube is connected to the arch wire is stably positioned in the slot of the chuck 3, which can effectively prevent the bracket or buccal tube from falling off, facilitate the positioning of the bracket or buccal tube, and improve the efficiency and quality of the bonding of the bracket or buccal tube.

[0032] During the process of bonding the reticulated plate of the buccal tube or bracket to the patient's tooth with glue, the thumb of the medical staff firmly presses against the upper block 2, and the upper block 2 makes the reticulated plate of the bracket or buccal tube firmly press against the patient's tooth, which can ensure the firm bonding of the bracket or buccal tube to the patient's tooth and reduce the labor intensity of the medical staff at the same time.

[0033] After the bracket or buccal tube is bonded to the patient's tooth, the medical staff uses the thumb to push the lever 6 to rotate. When the lever 6 rotates, the push plate 4 can squeeze the bracket or buccal tube, which can make the device move away from the patient's tooth, and the part of the bracket or buccal tube connected to the arch wire bonded to the patient's tooth exits from the rubber sleeve 5. The movement direction of the push plate 4 is perpendicular to the bracket or buccal tube bonded and fixed to the patient's tooth. Therefore, when the lever 6 rotates, the direction in which the device moves away from the patient's tooth is perpendicular to the bracket or buccal tube. When the device is separated from the bracket or buccal tube, it can prevent the bracket or buccal tube bonded and fixed to the patient's tooth from loosening and misaligning, and can ensure the firm bonding performance of the bracket or buccal tube to the patient's tooth.

[0034] The handle rod 1, the chuck 3 and the upper block 2 are integrally formed, and the handle rod 1, the upper block 2 and the chuck 3 are all made of high molecular polypropylene material. In this embodiment, the device is a disposable item, and the whole device can be discarded after use.

[0035] For devices of different specifications, the size of the slot of the chuck 3 and the size of the rubber sleeve 5 are different. Different sizes of brackets and buccal tubes can be bonded and fixed by using devices of different specifications.

The handle rod 1, the upper block 2 and the chuck 3 are all made of stainless steel. The handle rod 1 is threadedly connected to the upper block 2, and the chuck 3 is snap-connected to the upper block 2.

[0037] After the bracket and the buccal tube are bonded and fixed, the handle rod 1, the upper block 2 and the chuck 3 can be disassembled and disinfected, and the device in this embodiment can be recycled.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
