A gutta-percha point trimmer

Abstract

This invention provides a gutta-percha point trimmer, including a trimming tube with a perforated upper shell slidably connected to its upper end. A support frame is fixedly connected inside the trimming tube, and a motor is fixedly connected to the middle of the support frame. A docking block is fixedly connected to the output end of the motor. This design solves the problems of existing gutta-percha point trimmers, which require doctors to use both hands to operate the moving blade to trim the gutta-percha points, are small and prone to falling, and have the gutta-percha points get stuck on the blades. This invention has a reasonable structure and good practicality. By placing the trimming tube on the worktable, the gutta-percha point is simply inserted into the round hole on the surface of the perforated upper shell, allowing the rotating cutting propellant to trim the gutta-percha point. When the rotating cutting propellant becomes dull, the fixed base can be pulled out to replace it with a new rotating cutting propellant, which can prevent the rotating cutting propellant from scratching the doctor and also prevent the gutta-percha point from getting stuck on the blade.

Technical Field

[0001] This utility model is a gutta-percha point trimmer, belonging to the field of gutta-percha point technology. Background Technology

[0002] Guttate-gauge points are medical devices. They are generally made of rubber, which gives them good plasticity. They soften when heated to 40 degrees Celsius and harden when cooled. They fill tightly, have good tissue compatibility, can be easily removed from root canals, and are non-thermal and non-electrical.

[0003] Existing gutta-percha trimmers require dentists to use both hands to operate moving blades to trim the gutta-percha points. Their small size makes them prone to falling off, and the gutta-percha points can get stuck in the blades. There is an urgent need for a gutta-percha trimmer to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a gutta-percha tip trimmer to solve the problems mentioned in the background. This invention is highly practical. By placing the trimmer tube on the workbench, the gutta-percha tip is simply inserted into the round hole on the surface of the perforated upper shell, allowing the rotating cutting propellant to trim the tip. When the rotating cutting propellant becomes dull, the fixed base can be pulled out to replace it with a new one. This avoids the rotating cutting propellant scratching the dentist and also prevents the gutta-percha tip from getting stuck on the blade.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gutta-percha point trimmer, comprising a trimming tube, a perforated upper shell slidably connected to the upper end of the trimming tube, a support frame fixedly connected inside the trimming tube, a motor fixedly connected to the middle of the support frame, a docking block fixedly connected to the output end of the motor, and a fixed base fixedly connected to the lower end of the perforated upper shell.

[0006] The fixed base has a rotating groove in the middle, and a limiting rotating rod is rotatably connected in the rotating groove. The limiting rotating rod cooperates with the docking block. A rotating cutting slurry is fixedly connected to the upper end of the limiting rotating rod. Four docking sleeves are fixedly connected in the trimming tube. Four positioning slide rods are fixedly connected to the lower end of the perforated upper shell. The four positioning slide rods cooperate with the four docking sleeves.

[0007] Furthermore, a protective sleeve is fixedly connected to the circumferential surface of the trimming tube, and two protective bases are fixedly connected to the lower end of the trimming tube.

[0008] Furthermore, two actuating plates are fixedly connected to the circumferential surface of the perforated upper shell, and a protective pad is fixedly connected to the lower end of each of the two actuating plates.

[0009] Furthermore, the four positioning slide rods and the four docking sleeves are connected to each other by magnetic attraction.

[0010] Furthermore, the trimming tube has an inverted conical through hole.

[0011] Furthermore, the limiting rotating rod and the docking block are connected to each other by magnetic attraction.

[0012] The beneficial effects of this utility model: This utility model provides a gutta-percha point trimmer. Because it incorporates a perforated upper shell, a motor, a fixed base, a docking block, a limiting rotating rod, a rotating cutting impeller, a positioning slide rod, a docking sleeve, a rotating groove, and a docking block, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. By placing the trimming tube on the worktable, the gutta-percha point is simply inserted into the round hole on the surface of the perforated upper shell, allowing the rotating cutting impeller to trim the gutta-percha point. When the rotating cutting impeller becomes dull, simply pull out the fixed base to replace it with a new rotating cutting impeller. This avoids the rotating cutting impeller scratching the dentist and also prevents the gutta-percha point from getting stuck on the blade. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-8 This utility model provides a technical solution: a gutta-percha point trimmer, including a trimming tube 1, a perforated upper shell 4 slidably connected to the upper end of the trimming tube 1, a support frame 8 fixedly connected inside the trimming tube 1, a motor 7 fixedly connected to the middle of the support frame 8, a docking block 12 fixedly connected to the output end of the motor 7, a fixed base 9 fixedly connected to the lower end of the perforated upper shell 4, a rotating groove 15 formed in the middle of the fixed base 9, a limiting rotating rod 11 rotatably connected inside the rotating groove 15, and the limiting rotating rod 11 and the docking block 12... The connecting blocks 12 cooperate with each other, the upper end of the limiting rotating rod 11 is fixedly connected to the rotating cutting blade 10, the trimming tube 1 is fixedly connected to four docking sleeves 14, and the lower end of the perforated upper shell 4 is fixedly connected to four positioning slide rods 13. The four positioning slide rods 13 and the four docking sleeves 14 cooperate with each other. This design solves the problem that in the original device, the gutta-percha tip trimmer required the doctor to operate the moving blade with both hands to trim the gutta-percha tip, its small structure made it easy to fall off, and the gutta-percha tip would get stuck on the blade.

[0025] As the first embodiment of this utility model: a protective sleeve 2 is fixedly connected to the circumferential surface of the trimming tube 1, and two protective bases 3 are fixedly connected to the lower end of the trimming tube 1. The protective sleeve 2 installed on the surface of the trimming tube 1 can increase the friction between the trimming tube 1 and the hand, preventing the trimming tube 1 from falling when the doctor picks it up. The protective base 3 installed at the bottom of the trimming tube 1 can increase the friction between the trimming tube 1 and the workbench, preventing the trimming tube 1 from falling when it is impacted. Two actuating plates 5 are fixedly connected to the circumferential surface of the perforated upper shell 4, and a protective pad 6 is fixedly connected to the lower end of each actuating plate 5. The actuating plates 5 installed on the surface of the perforated upper shell 4 make it convenient for the user to lift the perforated upper shell 4 and replace the rotating cutting impeller 10. The four positioning slide rods 13 and the four docking sleeves 14 are connected to each other by magnetic attraction, which can increase the firmness of the connection between the perforated upper shell 4 and the trimming tube 1, so that the motor 7 can drive the rotating cutting impeller 10 to rotate, thereby cutting off the gutta-percha tip. The trimming tube 1 has an inverted conical through hole. The gutta-percha tip cut by the rotating cutting impeller 10 will fall out through the inverted conical through hole, preventing the gutta-percha tip from getting stuck in the rotating cutting impeller 10. The limiting rotating rod 11 and the docking block 12 are connected to each other by magnetic attraction. While the limiting rotating rod 11 and the docking block 12 cooperate with each other, they attract and fix each other, which allows the motor 7 to drive the rotating cutting impeller 10 to rotate.

[0026] As a second embodiment of this utility model: when cutting the gutta-percha tip, simply place the gutta-percha tip into the corresponding size round hole on the perforated upper shell 4. The motor 7 drives the rotating cutting impeller 10 to rotate and cut off the gutta-percha tip. If the gutta-percha tip cannot be cut, the perforated upper shell 4 can be removed by pinching the actuating piece 5. At the same time, the fixed base 9 pulls the rotating cutting impeller 10 inside it to move out. Then, the new perforated upper shell 4 is pressed onto the surface of the trimming tube 1, and the four positioning slide rods 13 are slid into the four docking sleeves 14 respectively. At the same time, the limiting rotating rod 11 is sleeved on the surface of the docking block 12. During the replacement of the rotating cutting impeller 10, it is possible to avoid scratching the doctor.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
