Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a drill bit calibration device used for implant navigation. Background Art

[0002] Dental implants, also known as implant dentures, are a type of bionic tooth made of biomaterials. They are divided into implants and restorations. The restoration and implant are combined with each other and implanted on bone tissue. Dental implants have the same structure and appearance as human teeth. The location of the implant requires extremely precise accuracy. Therefore, the process of implanting dental implants into the mouth requires superb implant technology.

[0003] At present, dental clinics need to spend a lot of energy to train qualified implant doctors to perform manual implantation, which increases the cost and risk of implantation to a certain extent. During the implantation operation, the doctor needs to operate the implantation mobile phone equipped with a drill to perform the implantation. Therefore, the real-time length, direction and position of the drill in the mouth have a great impact on the implantation. Calibration of the implantation mobile phone drill to obtain the drill parameters plays a vital role in the implantation operation. The drill calibration uses a calibration device to simulate the spatial position of the drill in the mobile phone and obtains the parameters through a visual positioning system. Therefore, the stability of the calibration device is required to be high. Most of the existing calibration devices have the problems of cumbersome assembly, low disc recognition accuracy and poor stability.

[0004] In view of this, we propose a drill calibration device for implant navigation. Utility Model Content

[0014] (1) In the present invention, the reflective device and the pre-tightening device are detachable parts.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 - Figure 5 As shown, a drill bit calibration device is provided at the front end of the implant mobile phone 2, and the drill bit calibration device includes a pre-tightening device and a reflective device. The reflective device and the pre-tightening device cooperate with each other to form the drill bit calibration device. The interface of the drill bit calibration device is a standard drill bit interface, which is adapted to most implant mobile phones on the market. The drill bit calibration device can rotate freely in the mobile phone, and the user can freely adjust the relative position according to needs;

[0025] The pre-tightening device includes a drill sleeve 6, a drill clamping rod 9 is arranged inside the drill sleeve 6, the end of the drill clamping rod 9 is consistent with the standard drill bit parameters, and can be tightly matched with the implant mobile phone 2 to prevent loosening. A spring 10 is sleeved on the drill clamping rod 9, and the spring 10 is in a pre-compressed state. The pre-tightening block 8 is coaxially matched with the drill sleeve 6, and the minor diameter of the spring 10 is coaxially matched with the outer diameter of the drill clamping rod 9, ensuring the smooth movement of the clamping block 8 and the spring 10. A clamping block 8 is arranged on the upper end of the spring 10, and the clamping block 8 can move with the compression of the spring 10. The spring 10 has a certain compression margin, so that the clamping block 8 has a certain pre-tightening force to prevent the wear of the calibration device.

[0026] The reflective device includes a drill bit positioning base plate 1, which has four arms and a calibration point at the end of each arm. Due to the guarantee of the roundness of the pressing plate, the circular contour and position accuracy of the drill bit positioning base plate 1 are extremely high. Four circular grooves are arranged on the drill bit positioning base plate 1, and an identification piece 4 is placed on each circular groove. An identification piece pressure plate 7 is arranged above the identification piece 4. The identification piece 4 is a circular thin piece with a coating on the surface. The identification piece pressure plate 7 cooperates with the drill bit positioning base plate 1 to press the identification piece 4. The drill bit positioning base plate 1 is provided with a stop groove to prevent the identification piece pressure plate 7 from rotating.

[0027] The drill sleeve 6 is provided with an internal thread and a guide hole, and the drill clamping rod 9 is provided with an external thread and a guide shaft. The internal thread and guide hole of the drill sleeve 6 cooperate with the external thread and guide shaft of the drill clamping rod 9. The spring 10 and the tightening block 8 are fixed to the drill positioning base plate 1 through the thread, and are placed in a confined space.

[0028] A drill sleeve 6 is connected to the top of the drill positioning base plate 1. A circular hole and a stop groove are opened on the drill positioning base plate 1. The circular hole and the stop groove ensure the coaxiality and position of the fit. A drill clamping rod 9 is inserted into the circular hole and the stop groove.

[0029] A mobile phone clamping assembly 5 is provided at the tail end of the planting mobile phone 2, and a mobile phone positioning device 3 is installed on the planting mobile phone 2. The mobile phone positioning device 3 is installed on the planting mobile phone 2, and cooperates with the drill bit calibration device to obtain the spatial position parameters of the drill bit and the mobile phone to complete the calibration.

[0030] When a drill bit calibration device for planting navigation is used, the operator needs to long press the button on the top of the head of the planting mobile phone 2, and then insert the end of the drill bit calibration device with the interface into the hole of the mobile phone. When it is inserted into place, release the button on the mobile phone end. At this time, the tightening block 8 moves downward under the compression of the planting mobile phone 2, and the spring 10 is compressed under the movement of the tightening block 8 to provide an upward supporting force. The drill bit calibration device is pre-tightened under the action of the force. Then, the user can rotate the drill bit positioning base plate 1 to adjust its relative position with the mobile phone. When the adjustment is completed, the visual navigation system calibrates the planting mobile phone assembly through the four marking points on the drill bit positioning base plate 1 to obtain spatial parameters such as the diameter and length of the mobile phone drill bit.
