[0050] See also Figures 1 to 4 The present application provides a tooth restoration holder, comprising a housing 1, a vacuum suction head 2, a negative pressure member 3, a first control switch 31 and a display screen 4.

[0051] The shell 1 is used for the doctor to hold it, and the shell 1 can be formed into a columnar structure, or one end can be bent at a certain angle as needed. It should be noted that when the shape of the shell 1 is that one end is bent at a certain angle, when the shell 1 is held, the area of ​​the shell 1 held by the hand will not block the bent end of the shell 1, so that the doctor can observe the operation of the vacuum suction head 2. Exemplarily, the bending angle of the shell 1 can be between 10-30 degrees.

[0052] The vacuum suction head 2 is arranged on one end surface of the housing 1, and the vacuum suction head 2 is used for sucking the patch or the inlay.

[0053] The negative pressure member 3 is disposed in the housing 1 and connected to the vacuum suction head 2 . The negative pressure member 3 is used to form negative pressure at the end of the vacuum suction head 2 .

[0054] It should be noted that the vacuum suction head 2 cooperates with the negative pressure member 3 to achieve negative pressure at the end of the vacuum suction head 2. Specifically, the vacuum suction head 2 may include a cylindrical member 21 and a flexible suction cup 22. One end of the cylindrical member 21 is connected to the negative pressure member 3, and the other end is sleeved with the flexible suction cup 22. The central area of ​​the flexible cup has a through hole so that the negative pressure generated by the negative pressure member 3 is transmitted to the flexible suction cup 22 through the cylindrical member 21, so that the flexible suction cup 22 can adsorb the patch or inlay. Exemplarily, the flexible suction cup 22 can be a rubber suction cup, and a through hole is provided in the center of the rubber suction cup so as to communicate with the outside world through the through hole. When the through hole is covered by the patch or inlay, the patch or inlay can be adsorbed on the rubber suction cup.

[0055] It should also be noted that the negative pressure member 3 may be a diaphragm pump, and the negative pressure member 3 has an air inlet and an air outlet, and the air inlet is connected to the vacuum suction head 2. The air outlet is used to discharge the air sucked in by the air inlet to the outside.

[0056] The first control switch 31 is disposed on the housing 1, and the first control switch 31 is electrically connected to the negative pressure member 3, and the first control switch 31 is used to control the operation of the negative pressure member 3. Specifically, the first control switch 31 may be a self-locking switch, and when the first control switch 31 is pressed once, the negative pressure member 3 is powered on, and the vacuum suction head 2 forms a negative pressure; when the first control switch 31 is pressed again, the negative pressure member 3 is powered off, and the vacuum suction head 2 no longer has a negative pressure.

[0057] The display screen 4 is arranged on the housing 1 and is used to display the working status of the negative pressure member 3 .

[0058] In this embodiment, a tooth restoration suction holder of the present application can allow a patch or inlay to be adsorbed on a vacuum suction head 2, thereby facilitating the removal of the patch or inlay, improving the doctor's work efficiency, and avoiding problems such as damage to the patch during the removal process and slipping of the inlay during the removal process.

[0059] In one embodiment, the tooth restoration holder further comprises a shading plate 5, which is arranged on an end surface of one end of the shell 1, and the area of ​​the shading plate 5 is larger than the axial cross-sectional area of ​​the shell 1, so that the shading plate 5 partially protrudes from the shell 1.

[0060] The shading plate 5 can be used to block the light, so as to prevent the light used during tooth restoration from being reflected into the doctor's eyes and affecting the doctor's sight. Preferably, the shading plate 5 is a plate-like structure, for example, a plate of a regular shape, such as a circular plate.

[0061] When a shading plate 5 is provided on the end surface of one end of the housing 1, the vacuum suction head 2 is arranged on the shading plate 5, and the vacuum suction head 2 passes through the shading plate 5 and is connected to the negative pressure member 3. When the housing 1 is bent at a certain angle, the bent end of the housing 1 is connected to the shading plate 5.

[0062] It should be noted that a cylindrical connector 51 is provided on the side of the shading plate 5 away from the housing 1, one end of the cylindrical connector 51 passes through the shading plate 5 and communicates with the negative pressure member 3 in the housing 1, the other end of the cylindrical connector 51 protrudes from the shading plate 5, and the end of the cylindrical connector 51 has a locking structure 52 for plugging, and the locking structure 52 is interlocked with the vacuum suction head 2. In other words, the hollow structure inside the cylindrical connector 51 enables the vacuum suction head 2 to be connected to the negative pressure member 3 to form an air passage. Specifically, the cylindrical member 21 is interlocked with the locking structure 52, thereby realizing an air passage connecting the negative pressure member 3, the cylindrical connector 51, and the cylindrical member 21, so that when the negative pressure member 3 is working, negative pressure will be generated at the flexible suction cup 22. Preferably, the cylindrical connecting member 51 is a metal tube. In this way, the cylindrical connecting member 51 can be prevented from being deformed when the negative pressure member 3 generates negative pressure, thereby preventing the negative pressure inside the cylindrical connecting member 51 from being reduced due to the deformation of the cylindrical connecting member 51, thereby affecting the negative pressure effect at the flexible suction cup 22.

[0063] It should also be noted that the locking structure 52 can be a sleeve, one end of the sleeve is the barrel mouth, and the other end is an integral or split structure with the cylindrical connector 51. Among them, the inner diameter of the sleeve gradually decreases from the barrel mouth to the inside of the sleeve, and the outer diameter of the end of the cylindrical member 21 plugged into the sleeve gradually decreases, so that when the cylindrical member 21 is plugged into the sleeve, an interference fit is achieved between the two, thereby achieving the interlocking of the sleeve and the cylindrical member 21. In addition, since the locking structure 52 is adopted at the end of the cylindrical connector 51, the cylindrical connector 51 can be separated from the cylindrical member 21. In this way, the vacuum suction head 2 can use the locking structure 52 to achieve the separation of the cylindrical member 21 and the cylindrical connector 51. After the vacuum suction head 2 is used, the cylindrical member 21 is separated from the cylindrical connector 51. Next, the vacuum suction head 2 can be sterilized at high temperature for subsequent patients to use. The vacuum suction head 2 can also be discarded to avoid repeated use, and cross infection when used by subsequent patients, which is not limited by the present application.

[0064] In one embodiment, the dental restoration holder further includes a battery 61 and a charging interface 62 .

[0065] Among them, the battery 61 is arranged in the housing 1, and is used to power the negative pressure part 3. The battery 61 can be a lithium battery. The battery 61 powers various parts of the dental restoration holder that use electricity. The charging interface 62 is arranged at an end of the housing 1 away from the visor 5 (the visor 5 is arranged on the front end face of the housing 1), that is, the charging interface 62 is arranged on the rear end face of the housing 1, and the charging interface 62 is connected to the battery 61. When the charging interface 62 is connected to an external power source, the battery 61 is charged. Exemplarily, the external power source is AC power.

[0066] It should be noted that when the battery 61 is disposed in the housing 1 , the battery 61 needs to be fixed in the housing 1 to prevent the battery 61 from shaking in the housing 1 .

[0067] In addition, the display screen 4 is connected to the battery 61 , and the display screen 4 is used to display the power level of the battery 61 .

[0068] In this embodiment, when the storage battery 61 is arranged in the housing 1, the tooth restoration holder can be used directly without an external power supply, and the storage battery 61 provides convenience for the use of the tooth restoration holder.

[0069] In one embodiment, the dental restoration holder further comprises an ultraviolet lamp 7 .

[0070] The ultraviolet lamp 7 is arranged on the side of the shading plate 5 away from the housing 1 and is connected to the battery 61 through a circuit; the ultraviolet lamp 7 is used to cure the adhesive used in the process of repairing and bonding the patch or inlay to the tooth, forming light curing.

[0071] Specifically, the number of ultraviolet lamps 7 can be multiple. Exemplarily, the number of ultraviolet lamps 7 is two, which are separately arranged on opposite sides of the vacuum suction head 2. The ultraviolet lamp 7 can be a low-frequency ultraviolet lamp. Exemplarily, the operating frequency of the low-frequency ultraviolet lamp 7 is 320-525nm. Preferably, the operating frequency of the ultraviolet lamp 7 is between 420-425nm, for example, 420nm, 421nm, 422nm, 423nm, 424nm, 425nm, and can also be other integer values ​​not shown in 320-525nm, which is not limited in the present application.

[0072] The second control switch 71 is disposed on the housing 1 and connected to the circuit between the ultraviolet lamp 7 and the battery 61. The second control switch 71 is used to control the on and off of the ultraviolet lamp 7. The second switch may be a touch switch, that is, the ultraviolet lamp 7 is turned on by pressing the second control switch 71 and according to the duration of pressing, and the ultraviolet lamp 7 is turned off when the second control switch 71 is released from being pressed.

[0073] The display screen 4 is connected to the ultraviolet lamp 7 , and the display screen 4 is also used to display the working status of the ultraviolet lamp 7 .

[0074] It should be noted that when the patch is coated with adhesive, after the patch is bonded to the broken position of the tooth with the adhesive, for the initial shaping of the adhesive, for example, an ultraviolet lamp 7 can be used to irradiate for 3-10 seconds so as to initially shape the adhesive. Next, the adhesive overflowing around the patch is removed using the corresponding adhesive cleaning equipment to ensure that only the adhesive for fixing the patch is left between the patch and the tooth. Preferably, the irradiation time of the ultraviolet lamp 7 is 5 seconds. In addition, the curing method of the adhesive is the same when it is used for inlay repair of tooth cavities, which will not be repeated.

[0075] It should also be noted that the shading plate 5 can be used to block the ultraviolet lamp 7 when it is irradiating, which is convenient for the doctor's work. In addition, since ultraviolet light is invisible, visible light is added to the ultraviolet lamp 7 so that the doctor can judge the irradiation duration of the ultraviolet light based on the irradiation duration of the visible light.

[0076] In one embodiment, the tooth restoration holder further includes a vibration motor 8. The vibration motor 8 is disposed in the housing 1, and the vibration motor 8 is connected to the battery 61 and the cylindrical connector 51 respectively, and the vibration motor 8 is used for the vibration of the cylindrical connector 51, so that the vacuum suction head 2 connected to the cylindrical connector 51 vibrates, so that the veneer or inlay forms a finger-shaped inlay with the tooth.

[0077] It should be noted that the vibration motor 8 is a small vibration motor 8, for example, a motor used in mobile phone energy devices. When the cylindrical connector 51 is a metal tube, the vibration motor 8 is fixedly connected to the metal tube to form a fitted state. In this way, when the vibration motor 8 vibrates, the vibration can be transmitted to the metal tube. Furthermore, the vibration of the vibration motor 8 can be transmitted to the vacuum suction head 2 through the cylindrical connector 51. That is to say, when the patch is bonded to the broken part of the tooth, the vacuum suction head 2 continues to be placed on the patch, and the vibration transmitted by the cylindrical connector 51 is used to increase the fluidity of the adhesive, so that the patch and the tooth form a finger-shaped inlaid structure, thereby ensuring the stability of the adhesive bonding the patch and the tooth. The vibration motor 8 is applied to the inlay, and the working method of the vibration motor 8 applied to the patch is the same, so it will not be repeated.

[0078] In addition, if Figure 3 As shown, the vibration motor 8 can also be arranged outside the housing 1 and fixedly connected to the cylindrical connecting member 51 outside the housing 1 to form a fitted state, so that when the vibration motor 8 vibrates, the vibration can be transmitted to the metal pipe to improve the vibration effect.

[0079] The third control switch 81 is arranged on the housing 1 and connected to the line between the vibration motor 8 and the battery 61. The third controller is used to control the opening and closing of the vibration motor 8. The third control switch is a touch switch. The working mode of the third control switch 81 is the same as that of the second control switch 71, which will not be repeated here.

[0080] The display screen 4 is connected to the vibration motor 8 , and the display screen 4 is also used to display the working status of the vibration motor 8 .

[0081] In the above embodiment, the first control switch 31, the second control switch 71 and the third control switch 81 can be set at a position that is easy to press behind the handheld housing 1. The present application does not limit the positions of the first control switch 31, the second control switch 71 and the third control switch 81.

[0082] The display screen 4 is respectively connected to the negative pressure member 3 , the ultraviolet lamp 7 and the vibration motor 8 for displaying the working status and frequency etc. The present application does not limit the content displayed on the display screen 4 .

[0083] In addition, a fourth button may be provided on the housing 1, and the fourth button is connected to the vibration motor 8 and is used to control the vibration frequency of the vibration motor 8, that is, the fourth button is pressed to cyclically adjust the operating frequency of the vibration motor 8. Exemplarily, the fourth button may be a touch button, which is not limited in the present application. For example, the operating frequency of the vibration motor 8 is divided into a first gear vibration frequency, a second gear vibration frequency and a third gear vibration frequency, and the vibration frequency of each gear is different. The operating frequency of the vibration motor 8 is adjusted by the fourth button, and the operating frequency of the vibration motor 8 is adjusted each time the fourth button is pressed, such as adjusting the operating frequency of the vibration motor 8 from the first gear vibration frequency to the second gear vibration frequency. In this way, when the third control switch 81 is pressed again, the vibration motor 8 can vibrate at the second gear vibration frequency.

[0084] Working principle:

[0085] The doctor holds the housing 1 and manually presses the first control switch 31 to make the negative pressure member 3 work, generating negative pressure at the end of the vacuum suction head 2, so that the patch or inlay is adsorbed by the vacuum suction head 2. Next, the patch is covered on the adhesive (in the case where the adhesive is coated on the tooth), or the inlay is inserted into the tooth cavity, so that the adhesive is separated between the inlay and the tooth cavity. During the bonding process between the patch and the adhesive, or the inlay and the adhesive, some of the adhesive will overflow. In this process, the third control switch 81 can be turned on, and the vacuum suction head 2 can be abutted against the patch or inlay, so that the patch or inlay forms a finger-shaped inlay with the tooth. In this way, the firmness of the bonding is ensured. After the finger-shaped inlay is completed, the third control switch 81 is turned off. Next, the second control switch 71 is turned on, so that the ultraviolet lamp 7 starts to work, and the ultraviolet lamp 7 is used to irradiate the location of the patch or inlay, and the ultraviolet lamp 7 is used to photo-cure the adhesive. At the same time, the shading plate 5 is used to block the ultraviolet rays to prevent the ultraviolet rays from affecting the doctor's work. After the ultraviolet lamp 7 irradiates for 5 seconds, the second control switch 71 is turned off and the ultraviolet lamp 7 stops working. At this time, the adhesive is in a semi-cured state, and the doctor can use the corresponding adhesive cleaning equipment to clean the overflowed adhesive. The overflowed adhesive is to be cleaned. Thus, the modification of the tooth by the veneer or inlay is completed.

[0086] In summary, the present application provides a tooth restoration holder, which has the advantages of improving the work efficiency of doctors using veneers or inlays to repair teeth, avoiding or reducing the breakage of veneers, reducing the falling of inlays, and facilitating the removal of veneers and inlays.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
