Description

Technical Field

[0001] The utility model relates to the technical field of root canal treatment, in particular to a handle for hot-melt gutta-percha filling. Background Art

[0002] Root canal therapy, also known as endodontic treatment, is a surgical procedure in dentistry to treat pulp necrosis and root infection. The principle of root canal therapy is to remove most of the infected substances in the root canal by mechanical or chemical methods, and to prevent periodontal disease or promote periapical healing of lesions by filling the root canal and sealing the crown. At present, the most commonly used method of root canal filling is to use a gutta-percha filling handle to heat and soften the gutta-percha, then pressurize the softened gutta-percha, and inject the gutta-percha into the root canal for filling.

[0003] The density of gutta-percha filling depends on the temperature of the heated gutta-percha, the filling pressure and the melting point of the gutta-percha used. Although increasing the heating temperature and filling pressure can improve the density of gutta-percha filling, increasing the heating temperature or filling pressure can easily lead to the injected gutta-percha temperature being too high or the pressure being too high, which can easily cause damage to the tooth root or periodontal tissue, affecting the patient's comfort and postoperative recovery. This makes it difficult for the existing filling handle to improve the density of the gutta-percha filling. Moreover, after the gutta-percha is heated and pressed, when the operator takes out the filling handle, it is easy to pull out part of the gutta-percha adhering to the tip of the filling handle, affecting the treatment effect. Utility Model Content

[0004] The utility model aims to provide a handle for hot-melt gutta-percha filling. By arranging a vibrator, the handle for hot-melt gutta-percha filling can generate vibrations to improve the fluidity of the gutta-percha and reduce the possibility of the gutta-percha adhering to the tip of the filling handle, so as to solve the problem that the existing filling handle is difficult to improve the filling density of the gutta-percha and is easy to bring out part of the gutta-percha adhering to the tip of the filling handle.

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

[0006] A handle for hot-melt gutta-percha filling comprises a shell and a treatment needle, wherein a chamber is arranged in the shell, and a control board and a vibrator are arranged in the chamber; the vibrator is electrically connected to the control board and is in contact with the inner wall of the shell or the control board so that the shell or the control board vibrates; one end of the treatment needle extends into the chamber, is connected and conducted with the control board so that the treatment needle can generate heat, and the end of the treatment needle extending into the chamber is close to the vibrator.

[0007] In some embodiments, a limiting portion is provided in the housing, and a mounting space for fixing the vibrator is provided in the limiting portion.

[0008] In some embodiments, the limiting portion is arranged in the chamber and protrudes from the inner wall of the shell, and the outer contour of the limiting portion is annular, and the installation space is formed inside the limiting portion.

[0009] In some embodiments, the shell is divided into a first side and a second side opposite to the first side, the first side is close to the needle head of the treatment needle, and the vibrator is arranged on the inner wall of the shell on the first side, and the control panel is arranged at the opening of the installation space.

[0010] In some embodiments, along the extension direction of the chamber, two ends of the control board are respectively connected to two ends of the chamber, and the control board is connected to the inner wall of the shell on the first side and the inner wall of the shell on the second side.

[0011] In some embodiments, the control panel is provided with an escape opening for evading the vibrator, and the vibrator is arranged in the escape opening.

[0012] In some embodiments, a limiting portion is provided on the control board, and a mounting space for fixing the vibrator is provided in the limiting portion.

[0013] In some embodiments, along the extension direction of the chamber, the vibrator is arranged beside the end of the treatment needle extending into the chamber.

[0014] In some embodiments, the vibrator is arranged on a peripheral side of the end of the treatment needle extending into the chamber.

[0015] Compared with the prior art, the hot melt gutta-percha filling handle of the utility model has the following beneficial effects:

[0016] The hot-melt gutta-percha filling handle of the present application is provided with a vibrator in the shell, and the vibrator is fitted with the inner wall of the shell or the control panel, so that the shell or the control panel can generate vibration. In this way, when the hot-melt gutta-percha filling handle is used for root canal treatment, under the same heating temperature and pressurization conditions, the vibration generated by the vibrator can be transmitted to the gutta-percha through the shell-treatment needle, causing the gutta-percha to vibrate, which is beneficial to the discharge of bubbles inside the gutta-percha, thereby improving the density of the gutta-percha. Moreover, when the hot-melt gutta-percha filling handle is taken out, the treatment needle no longer pressurizes the gutta-percha, and the vibration generated by the vibrator will only be transmitted to the gutta-percha in contact with the treatment needle, and will not continue to be transmitted to the gutta-percha in the root canal treatment area. In this way, the vibration generated by the vibrator will then increase the gap between the needle tip of the treatment needle and the gutta-percha it contacts, thereby making it easier for the treatment needle to fall out of the gutta-percha, reducing the possibility of the treatment needle bringing out the gutta-percha.

[0017] Moreover, the hot melt gutta-percha filling handle of the present application limits the layout positions of the control panel and the vibrator, so that the control panel can prevent the vibrator from escaping from the installation space and the vibrator is tightly connected to the shell, and the vibration generated by the vibrator can be better transmitted to the needle tip of the treatment needle.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0028] Example

[0029] refer to Figure 1-4 A handle 100 for hot-melt gutta-percha filling according to an embodiment of the utility model comprises a shell 1 and a treatment needle 2, wherein a chamber 3 is provided in the shell 1, a control board 4 and a vibrator 5 are provided in the chamber 3, one end of the treatment needle 2 extends into the chamber 3, is connected and conducted with the control board 4, and the end of the treatment needle 2 extending into the chamber 3 is close to the vibrator 5.

[0030] The treatment needle 2 of this embodiment is used to heat and pressurize the gutta-percha used for root canal treatment. The treatment needle 2 is electrically connected to the control board 4. Through the output control of the control board 4, the needle head of the treatment needle 2 can generate a large amount of heat, thereby heating and pressurizing the gutta-percha at the root canal. The heating process of the treatment needle 2 can refer to the impedance heating principle, which will not be repeated here.

[0031] The vibrator 5 of this embodiment is electrically connected to the control board 4 and can generate vibration based on the output control of the control board 4. The vibrator 5 can be any one of a rotor motor, a linear motor, a piezoelectric ceramic transducer, or other devices that can be used to achieve vibration. The drive circuit configured on the control board 4 can be determined according to the specific device selected for the vibrator 5, and will not be described in detail here.

[0032] The vibration generated by the vibrator 5 needs to be transmitted to the treatment needle 2, and the path of vibration transmission is different depending on the position of the vibrator 5. For example, the vibrator 5 can fit with the inner wall of the housing 1, so that the vibrator 5 can make the housing 1 vibrate, and the path of vibration transmission is vibrator 5→housing 1→treatment needle 2, and the vibration generated by the vibrator 5 is transmitted to the treatment needle 2 through the housing 1. The vibrator 5 can also fit with the control board 4 to make the control board 4 vibrate, so that the path of vibration transmission is vibrator 5→control board 4→treatment needle 2.

[0033] When the hot melt gutta-percha filling handle 100 is used for root canal treatment, the gutta-percha is filled into the treatment area of ​​the root canal. The operator holds the hot melt gutta-percha filling handle 100 and controls the heating and pressurization of the treatment needle 2 through the control panel 4, so that the gutta-percha in the root canal treatment area is softened. Moreover, during this process, the vibrator 5 can generate vibrations and transmit the vibrations to the needle head of the treatment needle 2 through the housing 1 or the control panel 4. During the root canal filling treatment, the needle head of the treatment needle 2 maintains pressure and close contact with the gutta-percha. In this way, the vibrations generated by the needle head of the treatment needle 2 will be transmitted to the inside of the gutta-percha, which helps to improve the density of the gutta-percha. For example, when there are bubbles inside the gutta-percha, the treatment needle 2 drives the gutta-percha to vibrate, which can facilitate the discharge of bubbles, thereby improving the density of the gutta-percha, and further improving the density of the root canal after filling.

[0034] After the root canal treatment is completed, when the handle 100 for hot-melt gutta-percha filling is taken out, the treatment needle 2 no longer applies pressure to the gutta-percha, and the vibration generated by the vibrator 5 will only be transmitted to the gutta-percha in contact with the treatment needle 2, and will not continue to be transmitted to the gutta-percha in the root canal treatment area. In this way, the vibration generated by the vibrator 5 will increase the gap between the needle head of the treatment needle 2 and the gutta-percha it contacts, thereby making it easier for the treatment needle 2 to come out of the gutta-percha, reducing the possibility of the treatment needle 2 bringing out the gutta-percha.

[0035] The following takes the fitting of the vibrator 5 and the housing 1 as an example to further illustrate the hot melt gutta-percha filling handle 100.

[0036] refer to Figure 1-2 , Figure 3 As an example of this embodiment, a limiting portion 6 is provided in the housing 1, and a mounting space 6a for fixing the vibrator 5 is provided in the limiting portion 6. Specifically, the limiting portion 6 is arranged in the chamber 3 and protrudes from the inner wall of the housing 1, and the outer contour of the limiting portion 6 is annular, and the mounting space 6a is formed inside the limiting portion 6.

[0037] By setting a limiting portion 6 in the chamber 3 and wrapping the vibrator 5 with the installation space 6a formed by the limiting portion 6, the tightness of the connection between the vibrator 5 and the shell 1 can be ensured, and after the vibrator 5 is wrapped by the installation space 6a, the vibration generated by the vibrator 5 can be transmitted to the shell 1 in time, and then transmitted to the treatment needle 2 through the shell 1.

[0038] Of course, in other examples, the limiting portion 6 may also be disposed on the control board 4, so that the vibrator 5 can be installed in the installation space 6a of the control board 4, and directly connected to the control board 4. The principle of configuring the limiting portion 6 on the control board 4 is the same as the principle of configuring the limiting portion 6 in the housing 1, and will not be illustrated here.

[0039] It is understandable that when the hot melt gutta-percha filling handle 100 is used for root canal treatment, the treatment needle 2 acts on the gutta-percha to heat and pressurize the gutta-percha. In order to better transmit the vibration to the treatment needle 2, the vibrator 5 should be close to the needle head of the treatment needle 2 to reduce the loss of vibration during the transmission process. Figure 1-3 As an example of this embodiment, the shell 1 is divided into a first side 1a and a second side 1b opposite to the first side 1a, the first side 1a is close to the needle head of the treatment needle 2, and the vibrator 5 is arranged on the inner wall of the shell 1 on the first side 1a, so that the vibration generated by the vibrator 5 can be transmitted to the treatment needle 2 through the shell 1, and when performing root canal treatment, the needle head of the treatment needle 2 is facing the treatment area of ​​the root canal, and the vibrator 5 is arranged on the first side 1a close to the needle head of the treatment needle 2, so that the vibration source generated by the vibrator 5 can be in the force application direction of the operator, which is more conducive to the operator holding the handle 100 for hot melt gutta-percha filling.

[0040] Of course, the vibrator 5 vibrates inside the housing 1, and there is a certain risk of loosening. In this regard, the control board 4 can be arranged at the opening of the installation space 6a, so that the displacement of the vibrator 5 in and out of the installation space 6a is limited, so that even if the vibrator 5 is loose, it will not be separated from the limit part 6, and the space inside the chamber 3 can be more fully utilized, so that the structure of the hot melt gutta-percha filling handle 100 can be more compact.

[0041] Specifically, refer to Figure 1-4 As an example of this embodiment, along the extension direction of the chamber 3, the two ends of the control board 4 are respectively connected to the two ends of the chamber 3, and the control board 4 is connected to the inner wall of the shell 1 located on the first side 1a and the inner wall of the shell 1 on the second side 1b. The control board 4 is provided with an escape opening 4a for escaping from the vibrator 5, and the vibrator 5 is arranged in the escape opening 4a.

[0042] By connecting the control board 4 to the inner wall of the shell 1 on the first side 1a and the inner wall of the shell 1 on the second side 1b, the control board 4 will be oriented in the same direction as the treatment needle 2. In this way, by using the circuits arranged on both sides of the control board 4, the shell 1 can be provided with control buttons located at two ends of the treatment needle 2, so that the operator can have a better user experience when using the hot melt gutta-percha filling handle 100. Moreover, when the vibrator 5 is fitted with the control board 4, the hot melt gutta-percha filling handle 100 can also form two vibration transmission paths, one of which is the vibrator 5→control board 4→treatment needle 2, and the other is the vibrator 5→control board 4→shell 1→treatment needle 2, so that the vibration generated by the vibrator 5 can be transmitted in multiple paths.

[0043] Moreover, after the control board 4 and the treatment needle 2 are arranged in the same direction, the vibration generated by the vibrator 5 only affects the side of the control board 4, and will not directly affect the circuits on the front and back of the control board 4, which can prevent the vibrator 5 from interfering with the control board 4 and causing the circuits on the control board 4 to be damaged due to vibration.

[0044] In addition, it is understandable that vibration will inevitably be attenuated when it is transmitted in an object, so the vibrator 5 can be as close to the front end of the housing 1 as possible to further reduce the loss of vibration during the transmission process. Figure 1-4 As an example of this embodiment, along the extension direction of the chamber 3, the vibrator 5 is arranged beside the end of the treatment needle 2 extending into the chamber 3, or the vibrator 5 is arranged around the end of the treatment needle 2 extending into the chamber 3.

[0045] The vibrator 5 is arranged beside the end of the treatment needle 2 extending into the chamber 3, or is arranged around the end of the treatment needle 2 extending into the chamber 3, both of which can make the vibrator 5 as close as possible to the front end of the shell 1, that is, the end side where the treatment needle 2 is located, under the premise of reasonable structural layout. In addition, the vibrator 5 is arranged beside the end of the treatment needle 2 extending into the chamber 3, or is arranged around the end of the treatment needle 2 extending into the chamber 3, which also makes the vibrator 5 closer to the treatment needle 2. In this way, the vibration generated by the vibrator 5 can be transmitted to the treatment needle 2 with less loss, and the vibrator 5 can be configured with a smaller power device, which is more conducive to the compact structure of the handle 100 for hot melt gutta-percha filling.

[0046] In summary, the embodiment of the utility model provides a hot melt gutta-percha filling handle 100, which sets a vibrator 5 in the shell 1, and makes the vibrator 5 fit with the inner wall of the shell 1 or the control board 4, so that the shell 1 or the control board 4 can generate vibration. In this way, when the hot melt gutta-percha filling handle 100 is used for root canal treatment, under the same heating temperature and pressurization conditions, the vibration generated by the vibrator 5 can be transmitted to the gutta-percha through the shell 1-treatment needle 2, so that the gutta-percha vibrates, which is beneficial to the discharge of bubbles inside the gutta-percha, thereby improving the density of the gutta-percha. Moreover, when the hot melt gutta-percha filling handle 100 is taken out, the treatment needle 2 no longer pressurizes the gutta-percha, and the vibration generated by the vibrator 5 will only be transmitted to the gutta-percha in contact with the treatment needle 2, and will not continue to be transmitted to the gutta-percha in the root canal treatment area. In this way, the vibration generated by the vibrator 5 will increase the gap between the needle head of the treatment needle 2 and the gutta-percha it contacts, so that the treatment needle 2 can be more easily removed from the gutta-percha, reducing the possibility of the treatment needle 2 bringing out the gutta-percha.

[0047] Moreover, the hot melt gutta-percha filling handle 100 of the present application limits the layout positions of the control panel 4 and the vibrator 5, so that the control panel 4 can prevent the vibrator 5 from escaping from the installation space 6a, and the vibrator 5 is tightly connected to the shell 1, and the vibration generated by the vibrator 5 can be better transmitted to the needle tip of the treatment needle 2.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
