Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a self-tooth transplantation fixing device. BACKGROUND

[0002] Self-tooth transplantation refers to transplanting a tooth with low utilization rate in the patient's oral cavity, such as wisdom tooth or supernumerary tooth, as a donor tooth into the tooth extraction socket (which can be referred to as a recipient tooth area) to continue to grow as a recipient tooth and play a role in the patient's oral cavity.

[0003] For example, the Chinese patent with publication number CN214104686U proposes a self-tooth transplantation fixing device, which includes an inner guide frame and an outer guide frame connected to each other along the direction of the tooth row. The inner guide frame includes a donor tooth inner guide frame and at least a first inner guide frame connected to one side of the donor tooth inner guide frame. The outer guide frame includes a donor tooth outer guide frame and at least a first outer guide frame connected to one side of the donor tooth outer guide frame. The donor tooth outer guide frame is spaced apart from the donor tooth inner guide frame, and the first outer guide frame is spaced apart from the first inner guide frame. The space between the donor tooth outer guide frame and the donor tooth inner guide frame is used to accommodate the donor tooth, and the space between the first outer guide frame and the first inner guide frame is used to accommodate other teeth on one side of the donor tooth. In this way, through the inner guide frame and the outer guide frame connected to each other, the position of the donor tooth in the recipient tooth area can be fixed and positioned, and the relative positional relationship between at least the other teeth on one side of the donor tooth and the donor tooth can be limited through the first inner guide frame connected to the donor tooth inner guide frame and the first outer guide frame connected to the donor tooth outer guide frame, thereby improving the stability of the position of the donor tooth during oral activity, providing a better growth environment for the donor tooth, and improving the success rate of self-tooth transplantation. However, in this scheme, the fixation between the outer guide frame and the inner guide frame is not stable enough, and the teeth do not fit well with the inner guide frame, resulting in poor fixation stability. Therefore, we propose a self-tooth transplantation fixing device SUMMARY

[0004] In view of the problems mentioned in the background, the purpose of the present application is to provide a self-tooth transplantation fixing device to solve the problems mentioned in the background.

[0005] The above technical purpose of the present application is achieved by the following technical scheme: The utility model provides an autologous tooth transplantation fixing device, including: first fixed frame, one side of first fixed frame is provided with second fixed frame, the inside connection of first fixed frame has first inner guide frame, the inside connection of second fixed frame has second inner guide frame, fixing assembly is arranged in one side of first fixed frame for fixing tooth, fixing assembly includes two fixed holes, two fixed holes are set up in one side of first fixed frame, one side of second fixed frame is provided with two fixed slots, the position of fixed slot corresponds with the position of fixed hole, the inside screw thread connection of fixed slot has fixed bolt, when first fixed frame and second fixed frame place are completed, through the rotation of fixed bolt, through the rotation of fixed bolt and drive first fixed frame to be close to second fixed frame, and the tooth for tooth and its adjacent tooth are fixed and limited.

[0006] Through the above technical scheme, by setting the fixing assembly, when in use, the medical staff places the first fixed frame and the second fixed frame in the tooth receiving area of the patient, so that the tooth for tooth is located at the intermediate position of the first fixed frame and the second fixed frame, and then the other teeth on both sides of the tooth receiving area are placed into the fixing device to assist in fixing. The first inner guide frame and the second inner guide frame are made of medical rubber, which improves the fitting degree of the fixing by adhering to the teeth. When the first fixed frame and the second fixed frame are placed, the fixed bolt is rotated to drive the first fixed frame to be close to the second fixed frame, thereby fixing and limiting the tooth for tooth and its adjacent teeth, thereby achieving the purpose of fixing the teeth.

[0007] Preferably, the fixing assembly further comprises: a plurality of first anti-skid pads connected to the inside of the first inner guide frame; a plurality of second anti-skid pads connected to the inside of the second inner guide frame; and two springs connected to one end of the fixed bolt.

[0008] Through the above technical scheme, by setting the first anti-skid pad, in application, the first anti-skid pad and the second anti-skid pad cooperate to increase the friction between the teeth and the first fixed frame and the second fixed frame, thereby improving the stability between the fixing device and the teeth, and thus improving the stability of the fixing. The spring can be compressed when the fixed bolt is rotated, generating a continuous counterforce to offset the loosening of the threads caused by vibration or impact, thereby preventing the fixed bolt from spontaneously rotating and falling off, resulting in unstable fixing, and further improving the stability of the fixing.

[0009] Preferably, a limiting groove is formed on the top surface of the first fixed frame and the second fixed frame, a protective plate is arranged in the limiting groove, an installation groove is formed on the bottom surface of the protective plate, and a first buffer pad is connected in the installation groove.

[0010] By adopting the above technical solution and setting a protective plate, the protective plate can be used to protect the upper part of the supply tooth during use, preventing the patient from causing damage to the supply tooth during the occlusion process. The first buffer pad can prevent the micro piezoelectric sensor from directly contacting the supply tooth, causing damage to the micro piezoelectric sensor. The first buffer pad can also be used to absorb the pressure on the supply tooth, reduce the pressure on the supply tooth, and improve the comfort of use.

[0011] Preferably, a micro piezoelectric sensor is connected to the inner bottom surface of the mounting groove, a wireless transmission module is connected inside the mounting groove, and the micro piezoelectric sensor and the wireless transmission module are electrically connected together.

[0016] By adopting the above technical solution and providing a second buffer pad, the second buffer pad can contact the teeth above the patient's affected area during use, thereby reducing the foreign body sensation during the patient's biting process and improving practicality.

[0017] Preferably, the top surface of the protective plate is provided with two mounting holes, the top surface of the limiting slot is provided with a positioning slot, the positions of the mounting holes correspond to the positions of the positioning slots, the inside of the mounting holes is connected with mounting bolts, and the mounting bolts extend through the mounting hole threads to the inside of the positioning slots.

[0018] By adopting the above technical solution and setting the mounting bolts, during installation, medical staff can rotate the mounting bolts to fix the protective plate and prevent the protective plate from moving in the limit groove, which causes the micro piezoelectric sensor to be unable to accurately monitor the occlusal force of the donor tooth, thereby improving the stability of monitoring.

[0019] Preferably, an instrument slot is provided on one side of the first fixing frame, two vibration slots are provided on one side of the interior of the instrument slot, a vibration motor is connected to the interior of the vibration slot, a baffle is provided inside the instrument slot, a card slot is provided on one side of the interior of the instrument slot, an elastic card block is connected to one side of the baffle, the elastic card block is movably connected to the card slot, two handle slots are provided on one side of the baffle, and a control chip is connected to the interior of the instrument slot.

[0020] By adopting the above technical solution and setting a vibration motor, when the micro piezoelectric sensor detects that the bite force is higher than the set threshold, the vibration motor generates a slight vibration to promptly remind the patient, preventing the patient from damaging the tooth supply position, thereby further improving safety. The baffle protects the vibration motor and the control chip, preventing them from being exposed in the cavity and affecting the patient's cavity, thereby improving practicality.

[0021] In summary, the present invention mainly has the following beneficial effects: By setting up a fixing component, when the first fixing frame and the second fixing frame are placed, by rotating the fixing bolt, the first fixing frame is driven to approach the second fixing frame through the rotation of the fixing bolt, and the supply tooth and the adjacent tooth are fixed and limited, thereby achieving the purpose of fixing the tooth. By setting up a first anti-slip pad, when used, the first anti-slip pad cooperates with the second anti-slip pad to increase the friction between the tooth and the first fixing frame and the second fixing frame, improve the stability between the fixing device and the tooth, thereby improving the stability of the fixation. The spring can be compressed when the fixing bolt is rotated to generate a continuous reaction force to offset the loosening of the thread caused by vibration or impact, avoid the fixing bolt from spontaneously rotating and falling off, resulting in unstable fixation, and further improve the stability of the fixation.

[0022] By setting up a protective plate, when in use, the protective plate can be used to protect the upper part of the donor tooth to prevent the patient from causing damage to the donor tooth during the biting process. The first buffer pad can prevent the micro piezoelectric sensor from directly contacting the donor tooth and causing damage to the micro piezoelectric sensor. The first buffer pad can also be used to absorb the pressure on the donor tooth, reduce the pressure on the donor tooth, and improve the comfort of use. By setting up a micro piezoelectric sensor, when in use, the bite force can be monitored in real time by the micro piezoelectric sensor. The monitored data can be transmitted to the patient's mobile phone through the wireless transmission module to perform a threshold alarm to remind the patient to control the bite force, avoid the patient from causing damage to the recipient tooth area, and improve safety.

[0023] Through the second buffer pad, the second buffer pad can be in contact with the teeth above the patient's dental area during use, reducing the foreign body sensation during the patient's occlusion, improving the practicability, and through the installation bolt, during installation, the medical staff rotates the installation bolt to fix and limit the protective plate, avoiding the movement of the protective plate in the limiting groove, causing the micro piezoelectric sensor to fail to accurately monitor the occlusion force received by the teeth, improving the stability of the monitoring.
