[0001] The utility model relates to the technical field of oral medicine application, in particular to a drug delivery rod for dental pulp resin filling. Background Art
[0002] After a tooth is cariously filled, secondary caries may spread to the pulp and cause pulpitis, so it is necessary to apply medicine to the filled part to reduce inflammation, and refill the part if necessary. In the prior art, the medicine is generally applied to the gums by applying powder or ointment with a medicine stick;
[0003] After searching, the patent number is CN219332060U, which discloses a dosing rod for endodontic resin filling. It has an additional drug application device. Through the U-shaped cross-sectional structure, it can fit the shape of the teeth well, which is convenient for applying medicine to the inside of the teeth, and it can rotate to apply medicine to the posterior molar part; however, the device cannot control the dosage when administering the medicine, and it is easy to administer too much or too little, resulting in poor filling effect. For this reason, we propose a dosing rod for endodontic resin filling. Utility Model Content

[0011] Preferably, a sliding groove is provided at the position where the sliding plate contacts the inner wall of the second positioning block, and the sliding plate is slidably connected to the sliding groove.
[0012] By adopting the above technical scheme, the blocking cap is pulled open by the handle so that the blocking cap disappears from the device body, and then the spiral disk is rotated so that the spiral disk, through the cooperation of the closing block and the rotating groove, moves the piston plate to the right inside the device body, stops when the piston plate fits the closing block, and then injects the medicine into the device body. After the injection, the blocking cap is again used to seal the device body, and then the tooth to be injected with the medicine is positioned through the cooperation of the first positioning block and the second positioning block, and then the spiral disk is rotated so that the spiral disk drives the piston plate to move to the left inside the device body. When the piston plate moves, the medicine will be injected into the tooth through the injection plate. At the same time, the dosage of the injected medicine can be controlled through the cooperation of the transparent plate and the scale bar, so that the drug delivery device can control the dosage of the medicine according to the actual situation, making the filling of the tooth body more convenient and precise, and improving the functionality of the drug delivery device.
[0013] By adopting the above technical solution, by pressing the recess on the right side of the side plate, the side plate is rotated around the second rotating block through the cooperation of the first rotating block and the plug column. When the side plate rotates, the first spring is pulled and the second positioning block is driven away from the first positioning block. At this time, the distance between the first positioning block and the second positioning block is increased, and then the inner side of the second positioning block is fitted to the tooth where medication needs to be administered. Then the side plate is loosened so that the side plate, with the cooperation of the first spring, makes the first positioning block fit the second positioning block. At this time, the second positioning block will push the connecting plate through the second spring, and then through the cooperation of the slide plate and the slide groove, the rubber plate can clamp and position the tooth bodies of different thicknesses, so that the medication device can clamp and position the tooth bodies of different thicknesses, which is convenient for the medication device to perform medication and improves the functionality of the medication device.
