Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an instrument for removing tooth roots. Background Art

[0002] Tooth root removal surgery, also known as root extraction, is a common surgery in oral and maxillofacial surgery. Root extraction refers to the surgery to remove the remaining roots when the crown and root of the tooth are separated and only the roots remain in the mouth. There are many reasons for the root to be broken during root extraction, such as root variation, apical periodontitis, improper operation by the doctor, etc., which may cause the root to be broken.

[0003] Broken roots are usually located at the bottom or side wall of the alveolar socket. Due to the influence of viewing angle or anatomical structure, it is difficult for doctors to remove the broken roots of teeth.

[0004] To this end, the present application proposes a tooth root removal instrument to assist doctors in removing tooth roots. Utility Model Content

A handle is fixedly connected to the upper surface of the magnet plate, and the stop rod and the fixed frame are both made of magnetic materials.

[0024] Through the above technical solution, the magnet plate and the stop rod cooperate with each other, so that the two finger rings can be adsorbed and fixed to each other, thereby driving the elbow pipe clamp to close.

[0025] Furthermore, a storage slot is provided on the surface of the fixing frame, and the sizes of the magnet plate and the storage slot are matched.

[0026] Through the above technical solution, when the device is working, the magnet plate is placed in the storage slot to prevent the magnet plate from affecting the work of the device.

[0040] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] like Figures 1 to 4As shown, an embodiment of the utility model provides a tooth root removal instrument, comprising: a rotating shaft 3; a rod body 1 and a rod body 2, which are hinged through the rotating shaft 3; two finger rings 4, which are respectively fixedly connected to one end of the rod body 1 and the rod body 2; two elbow pipe clamps 5, which are respectively fixedly connected to the other end of the rod body 1 and the rod body 2; two grooves 6, which are opened on the side of the rod body 1 and the rod body 2 that are close to each other, for removing the tooth root.

[0042] In this embodiment, firstly, the front end of the elbow pipe clamp 5 is set to be arc-shaped, which is convenient for the doctor to control the front end of the elbow pipe clamp 5 to enter the broken root in the patient's mouth. The operation process is: put the elbow pipe clamp 5 into the patient's mouth, at this time, the elbow of the front end of the elbow pipe clamp 5 is controlled to face the upper or lower gums; and the setting of the groove 6 makes it convenient for the elbow pipe clamp 5 to clamp the broken root in the groove 6, thereby improving the clamping effect of the broken root.

[0043] like Figures 1 to 4 As shown, one end of the elbow pipe clamp 5 is in an arc-shaped pointed shape, the cross-section of the groove 6 is semicircular, and the two elbow pipe clamps 5 form a round tube through the groove 6, and the thickness of the inner wall of the elbow pipe clamp 5 linearly becomes thinner from left to right along the horizontal axis.

[0044] In this embodiment, the front end of the elbow pipe clamp 5 is configured to be pointed and convex, and the front end is the thinnest part of the elbow pipe clamp 5, thereby reducing the resistance of the elbow pipe clamp 5 inserted into the tooth socket.

[0045] like Figures 5 to 7 As shown, the arc surface of the finger ring 4 is rotatably connected to a screw rod 7, one end of the screw rod 7 is fixedly connected to a knob 8, the inner wall of the finger ring 4 is slidably connected to a sleeve 9, one end of the sleeve 9 is fixedly connected to an arc plate 10, the sleeve 9 and the screw rod 7 are threadedly connected, an arc groove is provided on the arc surface of the finger ring 4, an arc rubber pad 11 is glued to the surface of the arc plate 10, and the size of the arc rubber pad 11 is matched with the arc groove.

[0046] In this embodiment, the thickness of fingers of different doctors is different, while the size of the finger ring 4 is fixed. When the finger enters the finger ring 4, there is a certain gap between the finger and the finger ring 4. When the thumb and index finger manipulate the two finger rings 4 to move away from each other, the finger ring 4 may be separated from the finger. Therefore, by rotating the screw 7 to drive the arc-shaped rubber pad 11 to restrict the finger to a certain extent, the separation between the finger and the finger ring 4 can be reduced.

[0047] like Figure 6 As shown, a sliding cavity 12 is provided on the surface of the finger ring 4, a sliding rod 13 is fixedly connected to the surface of the arc plate 10, and the sliding rod 13 and the sliding cavity 12 are slidably connected.

[0048] In this embodiment, the sliding rod 13 slides in the sliding cavity 12 to limit the moving direction of the arc-shaped rubber pad 11 and prevent the arc-shaped rubber pad 11 from shaking.

[0049] like Figure 5 and Figure 8 As shown, a stop rod 14 is fixedly connected to the surface of the rod body 2, a fixed frame 15 is fixedly connected to the surface of the rod body 1, a slot 18 is provided at one end of the fixed frame 15 close to the stop rod 14, a magnet plate 16 is slidably connected in the slot 18, a handle 17 is fixedly connected to the upper surface of the magnet plate 16, the stop rod 14 and the fixed frame 15 are both made of magnetic materials, a storage slot 19 is provided on the surface of the fixed frame 15, and the sizes of the magnet plate 16 and the storage slot 19 are matched.

[0050] In this embodiment, when the doctor finishes his work, he puts the magnet plate 16 into the card slot 18, and controls the stop rod 14 to contact the magnet plate 16 in the fixed frame 15. At this time, the stop rod 14 can be adsorbed and fixed, thereby avoiding separation between the two elbow pipe clamps 5, making it convenient for the next use of the instrument. When the instrument is in use, the magnet plate 16 is taken out through the handle 17 and placed in the storage slot 19 to avoid the magnet plate 16 affecting the use of the instrument.

[0051] In the embodiment of the utility model (working principle), when the broken root of the tooth is to be removed, first, the knob 8 is turned to drive the screw 7 to rotate, and the sleeve 9 drives the arc plate 10 and the arc rubber pad 11 to move under the action of the screw 7, and compresses the available space in the finger ring 4, so as to facilitate the fit of the finger ring 4 and fingers of different thicknesses. After the doctor inserts the thumb and index finger into the finger ring 4, the front end of the elbow pipe clamp 5 is inserted into the gap between the tooth root and the alveolar bone. The thumb and index finger control the two finger rings 4 to approach each other, and then control the elbow pipe clamp 5 on the rod body 1 and the rod body 2 2 to clamp the broken root. At this time, the removal of the broken root can be completed.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
