Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a pair of tooth crown clamping forceps. Background Art

[0002] When performing dental crown repair on patients, since the crown is highly polished and has a very smooth surface, it is very easy to slip when holding and passing it with gloves, which poses a risk of accidental swallowing or aspiration. When holding it with bare hands, it does not meet the infection control requirements, so there is an urgent need for a crown clamping tweezers in clinical practice.

[0003] For example, a dental crown clamp with patent publication number CN220175256U allows a sliding plate to slide through a driving mechanism, so that the clamping groove can be blocked with the top of the perforation to different degrees, so that the dental crown restoration can be fixed between the two.

[0004] However, during actual use, the above-mentioned crown clamping forceps cannot adapt well to different crowns due to the different sizes and shapes of patients' crowns. In addition, the device cannot adjust the angle of the crown well due to the different tooth positions of patients, which reduces the stability of the crown clamping and the practicality of the device. For this reason, the applicant proposes a crown clamping forceps. Utility Model Content

[0005] The utility model aims to provide a dental crown clamping forceps to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dental crown clamping forceps, comprising two soft heads of dental crown clamping forceps, a clamping mechanism is fixed on one side of each of the two soft heads of the dental crown clamping forceps, the clamping mechanism comprises two fixed cylinders, the two fixed cylinders are symmetrical to each other, the inner walls of the fixed cylinders contact a limiting plate, a rotating rod is fixed on one side of the limiting plate, one end of the rotating rod passes through one side of the inner wall of the fixed cylinder, a fixed plate is fixed on one side of the outer wall of the fixed cylinder, one side of both ends of the fixed plates are rotatably connected with movable plates, a rubber sheet is commonly fixed to the opposite surfaces of the two movable plates, and a plurality of first springs are fixed between one side of the rubber sheet and one side of the fixed plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When treating patients undergoing crown restoration, it is often necessary to use clamping forceps to put the crown in place, so a crown clamping forceps is needed. Most traditional crown clamping forceps cannot adapt well to the sizes of different crowns during actual use. When fixing the crown, the crown is easy to fall off, and there is a risk of accidental swallowing and aspiration. When holding the crown with gloves, the surface of the crown is smooth and easy to slip off, which also has the risk of accidental swallowing and aspiration. When holding it with bare hands, it does not meet the sensory control requirements, and because of the different tooth positions, the device cannot adjust the crown angle well, which reduces the stability of the crown clamping and the practicality of the device. For this reason, the applicant proposes a crown clamping forceps.

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a dental crown clamping forceps, comprising two dental crown clamping forceps soft heads 1, one side of the two dental crown clamping forceps soft heads 1 is respectively fixed with a clamping mechanism 2, the clamping mechanism 2 comprises two fixed cylinders 201, the two fixed cylinders 201 are symmetrical to each other, the inner wall of the fixed cylinder 201 contacts a limiting plate 202, one side of the limiting plate 202 is fixed with a rotating rod 203, one end of the rotating rod 203 passes through one side of the inner wall of the fixed cylinder 201, one side of the outer wall of the fixed cylinder 201 is fixed with a fixed plate 204, one side of both ends of the fixed plate 204 is respectively rotatably connected with a movable plate 205, the opposite surfaces of the two movable plates 205 are commonly fixed with a rubber sheet 206, one side of the rubber sheet 206 is fixed to one side of the fixed plate 204 There are several first springs 207, and a control mechanism 3 is fixed on one side of the clamping mechanism 2. The length of the control mechanism 3 is greater than the length of the clamping mechanism 2. The clamping mechanism 2 also includes a fixed block 208. One end of the rotating rod 203 passes through one side of the fixed block 208 and is fixed with a stabilizing plate 209. The other side of the outer wall of the fixed cylinder 201 is rotatably connected with a rotating plate 210. A second spring 211 is fixed between one side of the rotating plate 210 and one side of the fixed block 208. The rotating rod 203 is located inside the second spring 211. The areas of the limiting plate 202 and the stabilizing plate 209 are greater than the longitudinal cross-sectional area of ​​the rotating rod 203. The maximum height of the second spring 211 is greater than the distance between one side of the limiting plate 202 and one side of the inner wall of the fixed cylinder 201.

[0023] It should be noted that: when using the device, first operate the control mechanism 3 to make the two rubber sheets 206 approach each other and clamp the crown. As the crown is clamped continuously, the two sets of movable plates 205 will also limit the crown. Then, rotate the fixed plate 204 to adjust the angle of the crown. After that, continuously clamp through the control mechanism 3. At this time, one side of the limit plate 202 will contact one side of the inner wall of the fixed tube 201. At the same time, the second spring 211 will also be compressed to the shortest height. At this time, the rotating rod 203 will be limited, so that the adjusted angle of the crown is more stable. Then, adjust the angle of the two fixed blocks 208 to fine-tune the crown. Then, tighten the second limit handle 307 to limit the angle of the two fixed blocks 208.

[0024] like Figure 4As shown, the utility model provides a technical solution: a crown clamping tweezers, including a control mechanism 3, the control mechanism 3 includes a tweezers body 301, a rubber block 302 is fixed at the middle position of the tweezers body 301, handles 303 are respectively fixed on both sides of the tweezers body 301, and fixed rods 304 are respectively fixed at both ends of the tweezers body 301. The outer wall of the fixed rod 304 is slidably connected with a sliding tube 305, and a first limiting handle 306 is threadedly clamped on one side of the outer wall of one end of the sliding tube 305, and a second limiting handle 307 is threadedly clamped on the other end of the sliding tube 305, the threaded end of the first limiting handle 306 contacts one side of the fixed rod 304, and the other ends of the two sliding tubes 305 are respectively rotatably connected to one end of the two fixed blocks 208 in the clamping mechanism 2, and the threaded ends of the two second limiting handles 307 contact one side of the two fixed blocks 208 respectively.

[0025] It should be noted that: when using the device, first adjust the length between the sliding tube 305 and the fixed rod 304, then tighten the first limit handle 306 to limit the sliding tube 305, and then hold the two handles 303 to clamp the crown through the clamping mechanism 2.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
