Description

Technical Field

[0001] The utility model relates to the technical field of oral medical treatment, in particular to a precise trimmer for gutta-percha tips in the oral cavity. Background Art

[0002] Since the shape of the root canal is irregular and the size of the apical foramen is different, the gutta-percha tip needs to be properly trimmed in practical applications. In particular, the standard of the common gutta-percha tips is not enough. For some teeth with damaged apical foramen and missing apical barrier, if specific root canal filling requirements are to be met, the gutta-percha tips must be properly trimmed.

[0003] In the prior art, after the tip of the gutta-percha tip is trimmed, the doctor needs to re-determine the working length of the gutta-percha tip. This process requires the doctor to constantly use a measuring ruler to determine the length. The error in the operation is large, which is likely to affect the accuracy of the gutta-percha tip and thus affect the overall effect of root canal treatment. Moreover, constantly measuring the length of the gutta-percha tip with a measuring ruler will increase the risk of contamination of the gutta-percha tip. Therefore, we have introduced a precision trimmer for gutta-percha tips in the oral cavity. Utility Model Content

[0004] The purpose of the utility model is to provide an intraoral gutta-percha precision trimmer, which not only has high trimming precision for the gutta-percha tip and is not easy to be contaminated, but also is convenient for marking the working length of the gutta-percha tip, thereby improving work efficiency, being beneficial to subsequent root canal filling, and reducing adverse effects on root canal treatment, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A precise trimmer for gutta-percha tips in an oral cavity comprises a base, a platform is provided above the base, a limiting hole is provided at the upper end of the platform, a marking mechanism for marking the length of the gutta-percha tip is provided on one side of the upper end of the platform, rectangular holes are provided on both sides of the platform, a measuring ruler is slidably provided in the rectangular holes, the lower end of the measuring ruler is fixedly connected to the two sides of the base, threaded holes are provided on the hole walls on the opposite sides of the two rectangular holes, locking bolts are provided in the threaded holes, the measuring ruler is vertically arranged to the base, a turntable is provided at the middle part of the upper end of the platform through a rotating shaft, a plurality of positioning holes evenly distributed in an annular manner are provided on the top of the turntable, the limiting hole can correspond to the position of one of the positioning holes, and a trimming mechanism is provided between the turntable and the base.

[0007] Preferably, the marking mechanism includes a marking blade, which is arranged on the upper side of the platform, with sliding sleeves fixed at both ends of the marking blade, a sliding rod sliding inside the sliding sleeve, connecting blocks fixed at both ends of the sliding rod, the lower end of the connecting block is fixedly connected to the platform, and a spring is provided on the movable sleeve on one side of the sliding rod wall close to the limiting hole.

[0008] Preferably, the trimming mechanism includes a trimming blade, one end of which is rotatably connected to the rotating shaft, one end of which extends between the turntable and the base and is fixed with a push rod, a fixing rod is fixed to the upper end of the base, and a tension spring is installed between the fixing rod and the push rod.

[0009] Preferably, a disinfection tank is provided on the top of the platform between the measuring ruler and the slide bar, and the disinfection tank is filled with disinfectant.

[0010] Preferably, a rubber ring is interference-fitted inside the opening of the disinfection tank, and the upper end of the rubber ring extends outside the disinfection tank and is fixedly provided with a tank cover.

[0011] Preferably, a push plate is fixedly provided on the upper end of the marking blade.

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

[0013] The precise trimmer of the gutta-percha tip in the oral cavity is provided with a base, a rotating shaft, a rotating disk, a measuring ruler, a slot cover, a marking blade, a limiting hole, a push plate, a locking bolt, a platform, a trimming blade, a positioning hole, a push rod, a tension spring, a fixing rod, a spring, a sliding rod, a sliding sleeve, a connecting block and a rubber ring. After the gutta-percha tip passes through the limiting hole, the rotating disk is rotated according to the size of the gutta-percha tip, and the positioning hole on the rotating disk that matches the gutta-percha tip is rotated to the corresponding position of the limiting hole, the lower end of the gutta-percha tip is inserted into the corresponding positioning hole, and the push rod is pushed, which stretches the tension spring and drives the trimming blade to trim the tip of the gutta-percha tip. After the trimming is completed, the push rod is pulled The spring pulls the push rod and resets the trimming blade. At this time, loosen the two locking bolts, and the locking bolts no longer resist the measuring ruler. At this time, the platform can be slid up and down. According to the scale on the measuring ruler, when the marking blade moves to the specified scale, tighten the locking bolt and push the push plate. The push plate drives the marking blade to move. The marking blade squeezes the spring through the sliding sleeve, and the marking blade leaves a mark on the side of the gutta-percha point. Not only is the trimming precision of the gutta-percha point high, the gutta-percha point is not easy to be contaminated, but it is also convenient to mark the working length of the gutta-percha point, thereby improving work efficiency, facilitating subsequent root canal filling, and reducing the adverse effects on root canal treatment.
