TECHNICAL FIELD

[0001] The utility model relates to tooth extraction medical instrument technical field, concretely relates to a multifunctional minimally invasive tooth extraction elevator. BACKGROUND

[0002] In recent years, with the popularization of minimally invasive surgery concept and the development of technology, the field of oral medicine is also constantly exploring more efficient, safe and comfortable tooth extraction method, in oral surgery, tooth extraction is a common operation, especially in the treatment of wisdom teeth, severe dental caries or due to insufficient space resulting in tooth malposition, the doctor needs to frequently change tooth extraction tools to successfully complete the entire surgical procedure.

[0003] Although the traditional tooth extraction tool can meet the clinical demand in most cases, but in the treatment of complex cases, such as tooth root bending, tooth close to adjacent teeth or hard bone, etc., it may encounter greater difficulties, especially in the treatment of large root canal or large root apex teeth, the traditional tool often needs to grind a large amount of surrounding alveolar bone to obtain enough operation space, which not only increases the complexity and time of the operation, but also may cause postoperative complications, such as infection and pain, increasing the risk of patient pain and postoperative complications, therefore, we provide a multifunctional minimally invasive tooth extraction elevator to reduce the trauma of tooth extraction operation and shorten the operation time. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a multifunctional minimally invasive tooth extraction elevator, which can reduce the pain and time of patients during operation when performing complex dental pathological tooth extraction operation.

[0005] The technical scheme is as follows: a multifunctional minimally invasive tooth extraction elevator, comprising a mounting cylinder and a connecting ring, the mounting cylinder is a cylindrical structure and serves as the assembly carrier of the tooth elevator, the bottom of the mounting cylinder is fixedly connected with the connecting ring, and the connecting ring is used for mounting tooth extraction tools for assisting minimally invasive tooth extraction; further comprising: an H file, a circular hole is formed in the top of the mounting cylinder, the H file is rotatably installed at the top circular hole of the mounting cylinder, and the H file is used for rotating and pulling out after being inserted into the position of the root canal; a mounting plate is slidably installed in the interior of the mounting cylinder; a servo motor is installed on the mounting plate, the output shaft of the servo motor is connected with the rotating shaft of the H file; two electric push rods are symmetrically fixedly installed on the inner wall of the mounting cylinder, the telescopic rods of the electric push rods are connected with the mounting plate, the telescopic rods of the electric push rods are retracted, the servo motor and the H file are inserted into the position of the root canal through the mounting plate, the electric push rods and the servo motor are synchronously started, the electric push rods and the servo motor are cooperated with each other to rotate and pull out from the root canal, and finally the tooth extraction tools are installed on the mounting cylinder to assist tooth extraction, which can avoid a large amount of grinding of the surrounding alveolar bone, reserve more bone tissue for later implantation and embody the value of minimally invasive.

[0006] As an improvement to the above solution, the H-file is a spiral file made of stainless steel, with a total length of 28 mm and a tip diameter of 0.6 mm. The H-file has a large spiral angle and a zero tilt angle, and the cross-section of the H-file is circular.

[0007] As an improvement to the above solution, the tooth extraction tool includes a tooth extraction elevator and a hook rod. Both the tooth extraction elevator and the hook rod have spiral grooves on their ends away from the operating end. The inner wall of the connecting ring has threads that are adapted to the spiral grooves on the tooth extraction elevator and the hook rod. The tooth extraction elevator or the hook rod can be easily installed and replaced by rotating and screwing it into the connecting ring.

[0008] As an improvement to the above solution, a sealing ring is provided between the top circular hole of the mounting cylinder and the H-file. The sealing ring is used to improve the sealing performance of the H-file during use or cleaning, and to prevent water from flowing into the mounting cylinder and damaging the servo motor.

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] A multifunctional minimally invasive tooth extraction elevator, such as Figures 1-4 As shown, the device includes a mounting cylinder 1 and a connecting ring 2. The mounting cylinder 1 is a cylindrical structure and serves as the assembly carrier for the dental elevator. The connecting ring 2 is fixed to the bottom of the mounting cylinder 1 and is used to install extraction tools for assisting minimally invasive tooth extraction. It also includes: an H-file 6, with a circular hole at the top of the mounting cylinder 1. The H-file 6 is rotatably mounted at the circular hole at the top of the mounting cylinder 1 and is used for insertion into the root canal followed by rotation and extraction; a mounting plate 7, which is slidably mounted inside the mounting cylinder 1; a servo motor 8, mounted on the mounting plate 7, with the output shaft of the servo motor 8 connected to the rotating shaft of the H-file 6; and an electric push rod 1. Two electric push rods 10 are symmetrically fixed on the inner wall of the mounting cylinder 1. The telescopic rod of the electric push rod 10 is connected to the mounting plate 7. The telescopic rod of the electric push rod 10 retracts, and the mounting plate 7 drives the servo motor 8 and H-file 6 to be inserted into the root canal. Then, the electric push rod 10 and servo motor 8 are activated simultaneously, so that the electric push rod 10 and servo motor 8 cooperate to rotate and pull out from the root canal. Finally, the tooth extraction tool is installed on the mounting cylinder 1 to assist in tooth extraction. This can avoid a large amount of grinding away of the surrounding alveolar bone, preserve more bone tissue for later implantation, and demonstrate the value of minimally invasive surgery.

[0021] like Figure 2 As shown, H file 6 is a spiral file made of stainless steel. The total length of H file 6 is 28 mm and the diameter of its tip is 0.6 mm. H file 6 has a large spiral angle and its tilt angle is zero. The cross-section of H file 6 is circular.

[0022] like Figure 1 andFigure 4 As shown, the tooth extraction tool includes an extraction lever 3 and a hook rod 4. Both the extraction lever 3 and the hook rod 4 have spiral grooves 5 on their ends away from the operating end. The inner wall of the connecting ring 2 has threads that fit the spiral grooves 5 on the extraction lever 3 and the hook rod 4. The extraction lever 3 or the hook rod 4 can be easily installed and replaced by rotating and screwing it into the connecting ring 2.

[0023] like Figure 2 and Figure 3 As shown, a sealing ring 9 is provided between the top round hole of the mounting cylinder 1 and the H file 6. The sealing ring 9 is used to improve the sealing performance of the H file 6 during use or cleaning, and to prevent water from flowing into the mounting cylinder 1 and damaging the servo motor 8. The H file 6 is provided with a scale 11 on the outer wall of the rod of the mounting cylinder 1. The scale 11 is used to help doctors control the extension and retraction of the electric push rod 10 to drive the H file 6 more accurately, and improve the accuracy of drilling the H file 6 in the root canal. The outer periphery of the mounting cylinder 1 is provided with an anti-slip sleeve 12. The outer wall of the anti-slip sleeve 12 is provided with a rough texture. The anti-slip sleeve 12 is used to improve the stability of the user holding the mounting cylinder 1 to perform dental surgery.

[0024] When dealing with complex root canal issues, dentists can adjust the depth of the H-file 6 into the root canal by controlling the extension and retraction of the electric pusher 10. The design of the scale 11 helps dentists to more accurately control the insertion depth of the H-file 6. Once the H-file 6 reaches the predetermined position, the dentist will simultaneously activate the electric pusher 10 and the servo motor 8. The electric pusher 10 continues to provide a stable pushing force, ensuring that the H-file 6 can smoothly enter the root canal, while the servo motor 8 drives the H-file 6 to rotate, efficiently and precisely removing material from the root canal or preparing for subsequent tooth extraction, while minimizing damage to the surrounding alveolar bone and facilitating later implantation. By preserving more bone tissue and avoiding complications such as massive bleeding and nerve damage caused by excessive bone removal, after completing the H-file 6 operation, the doctor selects an appropriate extraction tool (such as an extraction elevator 3 or hook rod 4) according to the patient's specific tooth extraction situation. The spiral groove 5 designed on the extraction tool matches the thread on the connecting ring 2, and the extraction tool is installed onto the connecting ring 2 by rotation, which easily achieves quick installation and removal. In actual operation, the anti-slip sleeve 12 can increase the stability and comfort of holding the installation cylinder 1, while the sealing ring 9 effectively prevents water or other liquids from entering the interior of the installation cylinder 1, protecting the electronic components inside the installation cylinder 1 from damage.
