Description

Technical Field

[0001] The invention relates to the field of dental implants, and in particular to a device and method for detecting the reverse rotation angle of an implant connecting screw. Background Art

[0002] The implant system is subjected to severe and prolonged vibration during long-term use. Frequent vibrations will cause tiny gaps between the connecting screws and the abutment or cause the connecting screws to deform, thereby loosening the connecting screws. Loose connecting screws are prone to reverse rotation, resulting in a reduction in their preload. When the reverse rotation angle accumulates to a certain extent, the preload of the connecting screw is insufficient to lock the abutment, resulting in relative movement between the abutment, implant, and connecting screw. In severe cases, it can cause the components of the implant system to break or systemic failure. In addition, the appearance of tiny gaps between the various components can lead to a series of mechanical complications such as plaque deposition, soft tissue ingrowth, and fistula formation, making subsequent repair surgeries more complicated and more costly.

[0003] However, the reverse rotation angle of the connecting screw with insufficient preload is small and the abutment and implant are still in a locked state. It is difficult to measure the reverse rotation angle of the connecting screw and its preload condition without removing or destroying the denture. Summary of the invention

DETAILED DESCRIPTION

[0039] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] Reference Figures 1 to 5 As shown, the implant connection screw anti-rotation angle detection device of the present invention is implemented as follows:

[0044] Reference Figures 1 to 4 As shown, the implant connection screw anti-rotation angle detection device includes a mounting seat 100, a measuring module, a sliding resistor 200, a wireless communication module, and a connector 300.

[0045] The measuring module and the wireless communication module are disposed on the mounting base 100 . The sliding resistor 200 is mounted on the bottom of the mounting base 100 . The sliding resistor 200 is electrically connected to the measuring module.

[0046] The sliding resistor 200 is provided with a sliding piece 210 . The sliding piece 210 rotates around a vertical axis. After the sliding piece 210 rotates, the position changes so that the resistance value of the sliding resistor 200 changes. The parameter measured by the measuring module is affected by the resistance value of the sliding resistor 200 .

[0047] After the measurement module converts the measured parameters into electrical signals, the electrical signals are transmitted to the wireless communication module, and the wireless communication module converts the electrical signals into wireless signals, and the wireless communication module sends the wireless signals to the outside world.

[0048] The joint 300 is connected to the slide 210 , and the rotation axis of the joint 300 coincides with the rotation axis of the slide 210 .

[0049] Reference Figure 4 As shown, the mounting seat 100 is installed inside the base 910, and the outer wall of the mounting seat 100 cooperates with the inner wall of the base 910, so that the freedom of rotation of the mounting seat 100 around the vertical axis is limited, and the base 910 is locked into the implant 900 by the connecting screw 920, and the freedom of rotation of the base 910 around the vertical axis is limited.

[0050] The connector 300 is inserted into the screw groove at the top of the connecting screw 920 , and the connector 300 rotates synchronously with the connecting screw 920 . Therefore, when the connecting screw 920 rotates inversely, the connector 300 drives the slide 210 to rotate inversely.

[0051] The rotation angle of the slider 210 is associated with the resistance value of the sliding resistor 200 .

[0052] Changing the resistance of the sliding resistor 200 affects the parameters measured by the measuring module, and the parameters measured by the measuring module are associated with the wireless signal sent to the outside by the wireless communication module. A corresponding relationship is established based on the rotation angle of the sliding piece 210 and the wireless signal sent to the outside by the wireless communication module.

[0053] The mounting base 100 is connected to the base 910, and the connector 300 is connected to the connecting screw 920. The wireless signal sent by the wireless communication module is acquired and recorded. The rotation angle corresponding to the slide 210 is found as the original angle according to the wireless signal and the corresponding relationship.

[0054] After the implant system has been used for a period of time or the implant system has been subjected to a fatigue test, if the connecting screw 920 is reversely rotated, the connecting screw 920 drives the connector 300 to rotate the slide 210, thereby changing the resistance value of the sliding resistor 200 and causing the wireless signal sent by the wireless communication module to change.

[0055] According to the wireless signal and the corresponding relationship, the rotation angle corresponding to the slide 210 is found as the current angle, and the difference between the current angle and the original angle is the reverse rotation angle of the connecting screw 920 .

[0056] Therefore, the reverse rotation angle of the connecting screw 920 can be accurately measured without removing or destroying the denture 930.

[0057] In some embodiments, the sliding resistor 200 is provided with a resistor 220 , which extends along the rotation track of the slider 210 , and the slider 210 abuts against the resistor 220 . The measuring module is provided with a conductor 400 , and the conductor 400 abuts against the rotation axis of the slider 210 .

[0058] When the slide 210 rotates around the rotation axis, the conductor 400 of the measuring module abuts against the rotation axis of the slide 210, thereby ensuring that the length of the slide 210 connected to the measuring module remains unchanged at any angle.

[0059] At the same time, due to the high accuracy requirements for the reverse rotation angle measurement, a small resistance deviation of the sliding resistor 200 will also affect the measurement result of the reverse rotation angle. Therefore, ensuring that the length of the slide 210 connected to the measurement module remains unchanged at any angle will help improve the measurement accuracy of the reverse rotation angle of the connecting screw 920.

[0060] In some embodiments, the resistor 220 is in a ring shape, and the middle of the resistor 220 is cut off to make it C-shaped, so that the resistance value of the resistor 220 can be changed when the slider 210 abuts against the resistor 220 and slides.

[0061] The conductor 400 is separated from the resistor 220 , and the resistor 220 is electrically connected to the measurement module by providing a conductive structure to prevent the resistor 220 from being short-circuited by the conductor 400 .

[0062] The slider 210 extends along the radial direction of the resistor 220 , and both ends of the slider 210 extend to both sides of the axis of the resistor 220 . The rotation axis of the slider 210 coincides with the axis of the resistor 220 .

[0063] The slider 210 gradually bends upward from the rotation axis to both ends, so that the slider 210 is V-shaped. The top of one end of the slider 210 abuts against the bottom of the resistor 220 , and the top of the other end is provided with an insulator 211 abutting against the resistor 220 .

[0064] The two ends of the slide 210 are bent upwards to ensure that the tops of the two ends of the slide 210 are pressed against the bottom of the resistor 220, so as to ensure that the sliding resistor 200 is connected to the measurement module.

[0065] In some embodiments, the mounting base 100 is rotatably connected to the connector 300 , the conductor 400 and the connector 300 respectively press the upper and lower sides of the middle of the slide 210 , and a gap is left between the bottom of the end of the slide 210 and the connector 300 .

[0066] When the connecting screw 920 is reversed, the connecting screw will move upward and push the connector 300, and the connector 300 will squeeze the slide 210 and the conductor 400 upward. Since the slide 210 has a certain elasticity, the middle part of the slide 210 is pushed upward and deformed. The two ends of the slide 210 remain in contact with the resistor 220 due to the bending structure, avoiding the sliding resistor 200 from being disconnected from the measurement module due to the deformation of the slide 210.

[0067] In some embodiments, the detection device further includes a receiver 500, and the receiver 500 is used to receive the wireless signal sent by the wireless communication module.

[0068] The wireless signal sent by the wireless communication module is received promptly and accurately by the receiver 500 .

[0069] In some embodiments, the detection device further includes a power module, a wireless charging receiving coil 600 , and a wireless charging transmitting coil 700 .

[0070] The power module is disposed in the mounting base 100 , and provides electrical energy to the measuring module and the wireless communication module.

[0071] The wireless charging receiving coil 600 is also arranged in the mounting base 100, and the wireless charging receiving coil 600 is connected to the power module. The wireless charging transmitting coil 700 is arranged on the receiver 500, and the wireless signal sent by the wireless communication module is received by the receiver 500, and the receiver 500 uses the wireless charging transmitting coil 700 to charge the power module by interacting with the wireless charging receiving coil 600.

[0072] In some embodiments, the measuring module measures resistance.

[0073] By using the measurement module to measure the resistance, the resistance change of the sliding resistor 200 can be accurately reflected in the measurement result of the measurement module, reducing the calculation deviation and unit conversion deviation, so that the angle of the slider 210 rotating with the connecting screw 920 more accurately corresponds to the parameter measured by the measurement module.

[0074] In some embodiments, a bracket 120 is provided at the bottom of the mounting base 100. The bracket 120 is cylindrical, and a receiving space is reserved in the middle of the bracket 120. The bracket 120 is sleeved on the outside of the joint 300. The bottom of the bracket 120 is provided with a circular ring protruding inward, and the top of the joint 300 is provided with a flange protruding outward. The top of the joint 300 extends into the receiving space, and the bottom of the flange of the joint 300 is abutted against the top of the circular ring of the bracket 120, so that the joint 300 is kept at the bottom of the mounting base 100, and the sliding resistor is arranged in the receiving space.

[0075] The mounting base 100 holds the connector 300 at the bottom through the bracket 120 to prevent the connector 300 from deviating downward and causing the slider 210 to be separated from the sliding resistor 200 .

[0076] In some embodiments, the detection device further includes a sealing member 800 , a drying member 810 , and an elastic member 820 .

[0077] The seal 800 is used to seal the top of the abutment 910 of the implant system.

[0078] The drying member 810 is disposed below the sealing member 800 and is used to dry the internal environment of the base 910 to ensure the normal operation of the measuring module and the wireless communication module and to prevent the sliding resistor 200 from being short-circuited due to moisture.

[0079] The elastic member 820 is disposed below the drying member 810 , and the elastic member 820 abuts against the top of the mounting base 100 .

[0080] When the implant system is used for a long time, the denture 930 is affected by chewing and presses the base 910 downward, which may easily cause slight deformation of the base 910. The elastic member can prevent the base 910 from directly squeezing the measurement module and the wireless communication module in the mounting seat 100 after deformation.

[0081] Specifically, the implant connecting screw anti-rotation angle detection device of the present invention includes a mounting seat 100, a measuring module, a sliding resistor 200, a wireless communication module, a power module, a connector 300, a conductor 400, a receiver 500, a wireless charging receiving coil 600, a wireless charging transmitting coil 700, a sealing member 800, a drying member 810, and an elastic member 820.

[0082] The measuring module, the wireless communication module and the power module are mounted on the mounting base 100 . The power module provides power to the measuring module and the wireless communication module. The wireless communication module is electrically connected to the measuring module.

[0083] The wireless charging receiving coil 600 is disposed on the top of the mounting base 100 , and the wireless charging receiving coil 600 is electrically connected to the power module.

[0084] A gasket 110 and a bracket 120 are provided at the bottom of the mounting base 100. The bracket 120 is cylindrical, and a receiving space is reserved inside the bracket 120. A circular ring protruding inward is provided at the bottom end of the bracket 120. The gasket 110 is set in the receiving space and is in a circular ring shape.

[0085] The conductor 400 is disposed at the bottom of the mounting base 100 , the gasket 110 surrounds the outer periphery of the conductor 400 , and the conductor 400 is electrically connected to the measurement module.

[0086] An insulating sheet 111 extending downward is provided at the bottom of the gasket 110 , and a avoiding groove 112 penetrating vertically is provided on the side of the insulating sheet 111 of the gasket 110 .

[0087] The sliding resistor 200 includes a sliding piece 210 and a resistor 220 . The resistor 220 is in a circular ring shape and is provided with a notch. A conductive sheet 221 extending upward is provided on the top of the resistor 220 . The conductive sheet 221 is located beside the notch.

[0088] The resistor 220 is disposed at the bottom of the gasket 110 , the conductive sheet 221 extends upward through the avoidance groove 112 and is electrically connected to the measurement module, and the insulating sheet 111 is inserted into the notch of the resistor 220 .

[0089] The top of the joint 300 extends into the bottom end of the bracket 120. The top of the joint 300 is provided with a flange protruding outward. The bottom of the flange of the joint 300 abuts against the top of the ring of the bracket 120, so that the joint 300 is stuck on the bracket 120 and the joint 300 can rotate around the vertical axis.

[0090] A mounting groove 310 is provided at the top of the connector 300, and the slider 210 is arranged in the mounting groove 310. The slider 210 extends radially along the resistor 220, and the two ends of the slider 210 gradually bend upward from the middle to the outside, so that the slider 210 is V-shaped. The middle part of the slider 210 abuts against the conductor 400, and an insulator 211 is provided on the top of one end of the slider 210 to abut against the resistor 220, and the top of the other end of the slider 210 abuts against the resistor 220.

[0091] Therefore, the conductor 400 , the slider 210 , and the resistor 220 are electrically connected in sequence, and the slider 210 will change the effective length of the resistor 220 as the connector 300 rotates, thereby changing the resistance value of the connected measurement module.

[0092] The measuring module is used to measure the resistance value. The measuring module converts the measured resistance value into an electrical signal and sends it to the wireless communication module. The wireless communication module converts the received electrical signal into a wireless signal and sends it to the outside world.

[0093] The receiver 500 is used to receive the wireless signal sent by the wireless communication module. The receiver 500 is also provided with a wireless charging transmitting coil 700. When in use, the receiver 500 is placed above the mounting base 100. The power module is charged through the interaction between the wireless charging transmitting coil 700 and the wireless charging receiving coil 600. Then the power module provides power to the measuring module and the wireless communication module. The measuring module converts the measured resistance into an electrical signal and sends it to the wireless communication module. The wireless communication module converts the received electrical signal into a wireless signal and sends it to the outside world. The receiver 500 receives the wireless signal.

[0094] Reference Figure 6 As shown, the implant connection screw anti-rotation angle detection method of the present invention is implemented as follows:

[0095] The implant connection screw anti-rotation angle detection method is applied to the implant connection screw anti-rotation angle detection device as described above, and includes the following steps.

[0096] S100, obtaining the rotation angle of the slide 210 and the wireless signal sent by the wireless communication module, and establishing a corresponding relationship between the rotation angle and the wireless signal.

[0097] Before installing the detection device, rotate the slide 210 and record the rotation angle of the slide 210, then receive and record the wireless signal of the wireless communication module, change the rotation angle of the slide 210 and record the corresponding wireless signal, and then establish the corresponding relationship between the rotation angle and the wireless signal.

[0098] S200: Install the implant connecting screw anti-rotation angle detection device to the implant system, and obtain a first wireless signal sent by the wireless communication module.

[0099] After the detection device is installed, the first wireless signal sent by the wireless communication module can be received.

[0100] S300: Find a first angle according to the first wireless signal and the corresponding relationship.

[0101] Based on the correspondence between the rotation angle and the wireless signal, the corresponding first angle can be found from the first wireless signal. The first angle is the angle of the connector 300 and the slide 210 when the connecting screw 920 is pre-tightened in the initial state.

[0102] S400: After the implant system is used, a second wireless signal sent by the wireless communication module is obtained.

[0103] When the user uses the implant system to chew or the implant system undergoes a fatigue test, a second wireless signal is received.

[0104] S500: Find a second angle according to a corresponding relationship of a second wireless signal device.

[0105] Based on the correspondence between the rotation angle and the wireless signal, the corresponding second angle can be found from the second wireless signal. The second angle is the angle corresponding to the rotation of the connector 300 and the slide 210 caused by the reverse rotation of the connecting screw 920 after the implant system is used.

[0106] S600: Compare the first angle and the second angle to obtain a difference between the first angle and the second angle as a derotation angle.

[0107] The connecting screw 920 is at an initial position, and the connector 300 and the sliding sheet 210 are at a first angle corresponding to the initial position.

[0108] After the implant system is used for a period of time, the connecting screw 920 is reversely rotated, and the connector 300 and the sliding plate 210 are at a corresponding second angle after the connecting screw 920 is reversely rotated.

[0109] The reverse rotation angle of the connecting screw 920 can be obtained by subtracting the first angle from the second angle.
