Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, specifically to an accessory for invisible orthodontic treatment. Background Technology

[0002] Invisible braces are a type of dental orthodontics. The patient's teeth are digitally entered into a computer, and the movement and alignment of the teeth are simulated by software. Then, the tooth movement process is output and shaped using 3D printing technology. Attachments are made using light curing and other technologies, and the attachments are attached to the crowns. The invisible braces are made using pressure molding technology and worn into the patient's mouth to achieve the effect of orthodontic treatment.

[0003] During orthodontic treatment, injection needles are used to absorb and expel light-curing agents. During this process, staff need to frequently clean the tip of the injection needle to prevent the light-curing agent from sticking to the needle tip. Cleaning is usually done manually, which not only presents hygiene problems but is also very inconvenient. Based on this, Chinese Patent Publication No. CN220069884U discloses an accessory for invisible orthodontics. This patented technology uses the relative movement between the needle tip and a scraper to scrape off the residual light-curing agent adhering to the needle tip. The scraped-off light-curing agent residue falls onto a receiving plate. The entire process eliminates the need for manual wiping by staff, effectively ensuring the hygiene of the injection needle tip.

[0004] However, in the actual implementation of the above-mentioned patented technology, it is forgotten that the light curing agent is easy to stick to the needle tip after curing. Once it is cured on the needle tip, it is difficult to clean the needle tip by relying on the friction between the needle tip and the scraper. Therefore, it still has certain shortcomings in actual use.

[0005] In conclusion, it is necessary to invent an accessory for invisible orthodontic treatment. Utility Model Content

[0006] Therefore, this utility model provides an accessory for invisible orthodontic treatment to solve the problem that once the needle is solidified, it is difficult to clean the needle by relying solely on the friction between the needle and the scraper.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an accessory for invisible orthodontic treatment, comprising a box body, a sealing lid hinged to the top of the outer wall of the box body, a storage groove provided at the center of the top of the outer wall of the box body, a waste storage box placed in the storage groove, and a scraping mechanism for cleaning injection needles provided on the top of the outer wall of the box body and on both the front and rear sides of the waste storage box.

[0008] Preferably, the top of the outer wall of the box body and the front and rear sides of the storage slot are provided with receiving slots for storing injection needles, and the outer walls of the waste storage box are provided with levers for easy access by personnel.

[0009] Preferably, the scraping mechanism includes a base, and multiple bases are fixed to the top of the outer wall of the box and located on the front and rear sides of the waste storage box. Both sides of the top of the outer wall of the base are provided with outer arc-shaped blocks.

[0010] Preferably, the bottom of the front and rear ends of the inner wall of the base is fixed with a rotating shaft, and the bottom of the outer wall of the base is fixed with a hinge joint on the front and rear sides. The multiple hinge joints are evenly arranged in a strip array.

[0011] Preferably, the outer wall of the hinge joint has rotating holes on both the front and rear sides at positions corresponding to the rotating shaft. The outer wall of the rotating shaft is rotatably connected to the outer wall of the rotating shaft through the rotating holes. The inner wall of the rotating hole and the outer wall of the rotating shaft are provided with torsion springs for the outer arc block to reset.

[0012] Preferably, the two outer arc-shaped blocks can form a cylinder after docking, and the hinge joints fixed at the bottom of the two outer arc-shaped blocks are arranged in a staggered manner. The top of the outer wall of each outer arc-shaped block is fixed with a pressure plate for easy clamping by personnel.

[0013] Preferably, the inner wall of each of the outer arc-shaped blocks is provided with a scraper liner, the front end of the outer wall of the scraper liner is thin-cut, and the inner diameter of the scraper liner matches the injection needle.

[0014] Preferably, a buffer pad is provided on the inner wall of the outer arc-shaped block and on the outer wall of the scraper liner, and the outer wall side ends of the outer arc-shaped block are fixedly connected to the side wall of the scraper liner by fixing bolts.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, during use, the operator can place the injection needle tip between the scraper liner and then press the outer arc block with the pressure plate to rotate it inward, so that the scraper liner can wrap around the outer wall of the needle tip. Then, the operator can pull the injection needle outward, so that the scraper liner can scrape off the UV-curing agent on the outer wall of the needle tip. Compared with the prior art that uses a scraper, this invention has greater friction between the needle tip and the scraper, resulting in a better effect on scraping off the UV-curing agent.

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] See attached document Figures 1-7 The present invention provides an accessory for invisible orthodontic treatment, including a box body 100, a sealing cover 110 hinged to the top of the outer wall of the box body 100, a storage groove 130 opened at the center of the top of the outer wall of the box body 100, and receiving grooves 120 for storing injection needles opened on the top of the outer wall of the box body 100 and on the front and rear sides of the storage groove 130.

[0027] A waste storage box 200 is placed inside the storage tank 130. The outer walls of the waste storage box 200 are equipped with levers 210 for easy access. The waste storage box 200 is designed to be wider at the top and narrower at the bottom for easy placement and removal. Scraping mechanisms 300 for cleaning injection molding needles are located at the top of the outer wall of the box body 100 and on the front and rear sides of the waste storage box 200. Each scraping mechanism 300 includes a base 310, with multiple bases 310 fixed to the top of the outer wall of the box body 100 and on the front and rear sides of the waste storage box 200. The bases 310 support two outer arc-shaped blocks 320, allowing the blocks to rotate. Outer arc-shaped blocks 320 are located on both sides of the top of the outer wall of the base 310. Rotating shafts 322 are fixed to the bottom of the front and rear ends of the inner wall of the base 310. Hinges 321 are fixed on both the front and rear sides of the bottom of the wall. Multiple hinges 321 are evenly arranged in a strip array. Rotating holes are opened on the front and rear sides of the outer wall of the hinge 321 at positions corresponding to the rotating shaft 322. The outer wall of the rotating shaft 322 is rotatably connected to the outer wall of the rotating shaft 322 through the rotating holes. A torsion spring is provided on the inner wall of the rotating hole and on the outer wall of the rotating shaft 322 for the outer arc block 320 to reset. Specifically, the personnel can push the outer arc block 320 inward through the pressure plate at the top of the outer arc block 320. The outer arc block 320 can rotate on the rotating shaft 322 through the hinge 321 at the bottom, so that it can form a circle after closing. The torsion spring is provided so that the personnel can rotate the outer arc block 320 outward to reset after releasing the pressure plate, so that the outer arc block 320 is in the open state when not in use.

[0028] The two outer arc-shaped blocks 320 form a cylinder after docking. The hinge joints 321 fixed at the bottom of the two outer arc-shaped blocks 320 are staggered to prevent the two outer arc-shaped blocks 320 from getting stuck. Each outer arc-shaped block 320 has a pressure plate fixed to its top for easy clamping. Each outer arc-shaped block 320 has a scraper liner 330 on its inner wall. The front end of the scraper liner 330 is thin-edged. The scraper liner 330 can clamp onto the outer wall of the injection needle tip after the outer arc-shaped blocks 320 are closed. When the injection needle is pulled outwards, the UV-curing agent on the outside of the needle tip can be scraped off through the scraper liner 330. The thin-mouth design allows for cutting of the UV-curing agent when the injection needle is pulled, thus improving the removal efficiency of the UV-curing agent. The inner diameter of the scraper liner 330 matches the injection needle. A buffer pad 340 is provided on the inner wall of the outer arc block 320 and on the outer wall of the scraper liner 330. The outer side of the outer arc block 320 is fixedly connected to the side wall of the scraper liner 330 by fixing bolts 350. The fixing bolts 350 can fix the outer arc block 320 to the scraper liner 330, which facilitates the replacement of the scraper liner 330. The buffer pad 340 serves as a buffer and protection. The scraper liner 330 can be made of metal.

[0029] The usage process of this utility model is as follows: First, personnel can assemble the device according to the above instructions. After completion, the scraper liner 330 can be taken out and fixed to the inner wall of the outer arc block 320 by fixing bolts 350. When in use, personnel can take out the injection needle in the receiving groove 120 for use.

[0030] When it is necessary to remove the UV-cured agent from the injection needle tip, the operator can first remove the waste storage box 200 and place it in the storage tank 130. Then, the injection needle tip can be placed between the scraper liners 330. The operator then holds the pressure plate with both hands to slide the scraper liners 330 inwards, allowing them to wrap around the outer wall of the injection needle tip. The operator can then pull the injection needle outwards, causing the needle tip to slide along the inner wall of the scraper liners 330. The liner 330 can scrape off the UV-curing agent on the injection needle. After scraping, the operator can release the pressure plate. Under the action of the torsion spring, the outer arc block 320 will rotate outward and unfold. The scraping liner 330 can drop the scraped UV-curing agent into the waste storage box 200 for storage. When the waste storage box 200 is full, the operator can take out a long strip to seal the top of the waste storage box 200. Then, the waste storage box 200 can be taken out through the lever 210 to clean up the waste.
