Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a tool kit for extracting horizontal impacted wisdom teeth. Background Art

[0002] Horizontally impacted wisdom teeth are common in clinical practice. Their hazards include: damaging the normally growing molars in front, causing food impaction, pericoronitis of wisdom teeth, etc. The conventional clinical treatment method is to extract wisdom teeth. Extracting wisdom teeth is a complex operation in dentistry, especially for horizontally impacted wisdom teeth. The traditional extraction method is: 1. Remove resistance, that is, remove the bone resistance that hinders tooth extraction, 2. Use a dental elevator or extraction forceps to remove the wisdom teeth.

[0003] The main problems with wisdom tooth extraction in the prior art are: 1. Unlike other teeth that grow vertically, wisdom teeth grow horizontally, and most or all of the horizontally grown wisdom teeth are buried in the alveolar bone, and are surrounded by the alveolar bone on the buccal and lingual sides, making it difficult to clamp them with tooth extraction forceps (the tooth needs to be clamped with an instrument to be extracted); 2. Tooth extraction instruments often use the bone plates around the wisdom teeth as a fulcrum to push the wisdom teeth out, but when pushing the affected teeth out, the pressure on the fulcrum and the surrounding bone and soft tissues is difficult to control, and excessive force can easily cause damage to the surrounding alveolar bone and gums, resulting in prolonged wound healing time; 3. Wisdom teeth are located deep in the mouth, and the operating space and field of view of the instruments are limited, requiring patients to open their mouths for a long time and widely, causing discomfort to patients. Summary of the invention

[0004] In order to solve the problem of difficulty in removing wisdom teeth in the prior art, the present invention provides a tool kit for removing horizontally impacted wisdom teeth. The tool kit for removing horizontally impacted wisdom teeth can conveniently and quickly remove wisdom teeth through the principle of leverage, thereby reducing clinical operation time and patient pain.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A tool kit for horizontal impacted wisdom tooth extraction, comprising:

[0007] A connecting nail, the connecting nail comprises a head section and a tail section which are connected in sequence, the tail section can be inserted into the impacted wisdom tooth and connected and fixed to the impacted wisdom tooth, and the head section is an annular structure;

[0008] A support base, the outer surface of which can be matched and connected with the buccal alveolar bone surface of the impacted wisdom tooth;

[0009] The dental elevator is a rod-shaped structure. The front part of the dental elevator can pass through the head section, and the front end of the dental elevator can abut against the support base. Under the action of power, the dental elevator can rotate in the direction away from the impacted wisdom tooth with the support base as a fulcrum. During the rotation of the dental elevator, the connecting pin can bring resistance to the dental elevator.

[0010] The beneficial effects of the present invention are:

[0011] 1. Solve the problem that horizontal impacted wisdom teeth are difficult to extract or that the tooth elevator is difficult to pull out. The wisdom teeth can be extracted by means of the lever principle, which reduces the clinical operation time and is convenient to operate.

[0012] 2. Prevent patients from opening their mouths wide for a long time, reduce their discomfort, reduce clinical operation time, and make the application more convenient.

[0013] 3. The pressure sensor, torque wrench and other devices equipped can detect the strength of the force to prevent excessive force during operation and cause trauma to the alveolar bone and gums around the wisdom teeth. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0033] For the convenience of understanding and description, the following description of the present invention adopts an absolute positional relationship. Without special explanation, the orientation word "up" represents the direction perpendicular to Figure 3 the paper surface and pointing outside the paper surface, the orientation word "down" represents the direction perpendicular to Figure 3 the paper surface and pointing inside the paper surface, the orientation word "left" represents Figure 3 the left direction in Figure 3 the right direction in Figure 3 the upper side direction in Figure 3 the lower side direction in

[0034] As Figures 1 to 4 , Figure 7 and Figure 8 shown, a tool kit for extracting horizontally impacted wisdom teeth according to the embodiments of the present invention includes:

[0035] A connecting nail 1, the connecting nail 1 comprises a head section 101 and a tail section 102 which are connected in sequence, the tail section 102 can be inserted into the impacted wisdom tooth 6 and connected and fixed to the impacted wisdom tooth 6, and the head section 101 is an annular structure;

[0036] A support base 2, the outer surface of the support base 2 can be matched and connected with the buccal alveolar bone surface 7 of the impacted wisdom tooth 6;

[0037] The dental lifter 3 is a rod-shaped structure. The front part of the dental lifter 3 can pass through the head section 101. The front end of the dental lifter 3 can abut against the support base 2. The dental lifter 3 can rotate in a direction away from the impacted wisdom tooth 6 with the support base 2 as a fulcrum under the action of power. During the rotation of the dental lifter 3, the connecting pin 1 can bring resistance to the dental lifter 3.

[0038] The dental elevator 3 is equivalent to a lever. The doctor applies power to the dental elevator 3, and the impacted wisdom tooth 6 applies resistance to the dental elevator 3. The contact point between the front end of the dental elevator 3 and the supporting base 2 is a fulcrum.

[0039] like Figure 1 to Figure 2 As shown, the function of the connecting nail 1 is to become a connecting bridge between the dental elevator 3 and the impacted wisdom tooth 6. The tail section 102 of the connecting nail 1 is a cylindrical structure, and the head section 101 is located at one end of the tail section 102. The tail section 102 of the connecting nail 1 has an external thread, which is a self-tapping thread. After drilling a hole 8 on the impacted wisdom tooth 6, the tail section 102 of the connecting nail 1 is screwed into the hole 8, and the connecting nail 1 can be connected and fixed to the impacted wisdom tooth 6.

[0040] The head section 101 is connected to one end of the tail section 102 as a whole, and the head section 101 can be a closed ring or an open ring (such as a hook shape). The connection method of the connecting nail 1 and the impacted wisdom tooth 6 can also be other ways, for example, the outer surface of the tail section 102 of the connecting nail 1 contains a barb structure. Alternatively, the outer surface of the tail section 102 of the connecting nail 1 is a smooth surface, and the connecting nail 1 and the impacted wisdom tooth 6 are bonded and fixed by an existing quick adhesive.

[0041] The function of the support base 2 is to act as a fulcrum, so that the dental lifter 3 can pry the impacted wisdom tooth 6 out of the alveolar bone by the lever principle. When in use, the support base 2 is matched and connected with the buccal alveolar bone surface 7. In order to avoid excessive pressure from the support base 2 on the buccal alveolar bone and damage to the buccal alveolar bone, the support base 2 is 3D printed, so that the outer surface of the support base 2 can be completely matched and fitted with the buccal alveolar bone surface 7 of the impacted wisdom tooth 6 to disperse the pressure and avoid local pressure concentration.

[0042] like Figure 8As shown, the support base 2 can be block-shaped or plate-shaped, and the material of the support base 2 can be metal or plastic. The 3D printing support base 2 is a prior art. In order to prevent the front end of the dental lifter 3 from slipping or moving when prying the impacted wisdom tooth 6, an abutment groove 201 is provided on the inner surface of the support base 2. The front end of the dental lifter 3 can abut in the abutment groove 201 of the support base 2. When in use, the front end of the dental lifter 3 will not slide out of the abutment groove 201.

[0043] like Figure 8 As shown, in order to prevent the support base 2 from applying too much pressure to the buccal alveolar bone surface 7 and damaging the buccal alveolar bone surface 7, a pressure sensor 202 is connected to the outer surface of the support base 2, and the tool kit for horizontal impacted wisdom tooth extraction also includes a pressure display device, which is connected to the pressure sensor 202 through a cable, and the pressure display device can display the pressure applied to the pressure sensor 202. The appropriate pressure value applied by the support base 2 to the buccal alveolar bone surface 7 can be obtained through a limited number of experiments.

[0044] The outer surface of the support base 2 may be provided with a sensor mounting groove, and the pressure sensor 202 may be matched and mounted in the sensor mounting groove, and the pressure sensor 202 may be matched and connected with the buccal alveolar bone surface 7. The pressure display device may display the pressure applied to the pressure sensor 202, which is a prior art. When in use, the pressure value displayed by the pressure display device may be observed in real time to prevent the support base 2 from applying too much pressure to the buccal alveolar bone surface 7 and damaging the buccal alveolar bone surface 7.

[0045] like Figure 3 to Figure 4 As shown, the dental lifter 3 comprises a lever section 301 and a handle section 302 connected front and back. The lever section 301 can be a straight rod structure or a curved rod structure. Preferably, the lever section 301 is made of metal, is a curved rod structure, comprises a first rod section 303, a second rod section 304 and a third rod section 305 connected in sequence from back to front, and the handle section 302 is fixed to the rear end of the first rod section 303.

[0046] The first rod segment 303 extends in the front-to-back direction, the second rod segment 304 extends in the left-to-right direction, and the third rod segment 305 extends in the up-down direction. The length of the first rod segment 303 is greater than the length of the second rod segment 304, and the length of the second rod segment 304 is greater than the length of the third rod segment 305. When in use, the second rod segment 304 and the third rod segment 305 can both be located in the patient's oral cavity.

[0047] Both the second rod segment 304 and the third rod segment 305 can pass through the head segment 101, one end of the third rod segment 305 is connected to the second rod segment 304, and the other end of the third rod segment 305 can abut against the support base 2 to form an abutment point. The dental elevator 3 can rotate around the first axis 5 in the direction away from the impacted wisdom tooth 6 with the abutment point as a fulcrum under the action of power. The first axis 5 is parallel to the extension direction of the first rod segment 303, and the first axis 5 passes through the abutment point.

[0048] like Fig.13 As shown, in order to avoid excessive power applied to the dental elevator 3 and damage to the buccal alveolar bone surface 7, the tool kit for horizontal impacted wisdom tooth extraction also includes: a torque wrench 4, which can be a product of the prior art, and can be connected to the handle section 302. The torque wrench 4 can provide the power to the dental elevator 3, and the torque wrench 4 can display the value of the power or torque. The appropriate power value provided by the torque wrench 4 to the dental elevator 3 can be obtained through a limited number of experiments.

[0049] The following describes how to use the tool kit for removing horizontal impacted wisdom teeth.

[0050] 1. Scan the buccal alveolar bone surface 7 of the impacted wisdom tooth 6, and make the support base 2 by 3D printing, so that the outer surface of the support base 2 can match and fit with the buccal alveolar bone surface 7 of the impacted wisdom tooth 6.

[0051] 2. If necessary, first cut and turn over the gums to expose the impacted wisdom tooth 6 and the buccal alveolar bone surface 7, and drill a hole 8 in the center of the impacted wisdom tooth 6. Figure 5 and Figure 6 shown.

[0052] 3. Insert the tail section 102 of the connecting nail 1 into the hole 8. For example, the outer surface of the tail section 102 is provided with a self-tapping thread. Screw the tail section 102 into the hole 8 to connect and fix the connecting nail 1 and the impacted wisdom tooth 6. Install a pressure sensor on the lower surface of the support base 2. The pressure sensor is connected to the pressure display device. The outer surface of the support base 2 is matched and connected with the buccal alveolar bone surface 7 of the impacted wisdom tooth 6. Figures 7 to 10 shown.

[0053] 4. The third rod segment 305 and the second rod segment 304 pass through the inner hole of the head segment 101 in sequence, and the other end of the third rod segment 305 abuts against the abutting groove 201 of the support base 2 to form an abutting point, such as Fig.11 and Fig.12 shown.

[0054] 5. The torque wrench 4 is connected to the handle section 302 of the dental elevator 3. The torque wrench 4 provides power to the dental elevator 3. Under the action of the power, the dental elevator 3 rotates around the first axis 5 in a direction away from the impacted wisdom tooth 6 with the abutment point as a fulcrum, overcoming the resistance brought to the dental elevator 3 by the connecting pin 1 and the impacted wisdom tooth 6. The first axis 5 is parallel to the extension direction of the first rod section 303. The impacted wisdom tooth 6 can be pulled out of the alveolar bone by using the lever principle. Fig.13 shown.

[0055] The above is only a specific embodiment of the present invention, and cannot be used to limit the scope of the invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the protection scope of the present invention, should still fall within the scope of this patent. In addition, the technical features of the present invention can be freely combined with each other, with technical features and technical solutions, and with technical solutions.
