Abstract

The present invention discloses an implant filler and a method for using the same. Since the coil is arranged in a closed cavity of the implant, and the position where the bottom of the coil is disconnected abuts against the bottom wall of the closed cavity, when the implant leaks, liquid flows into the closed cavity of the implant, and the liquid acts as a conductor to form a closed loop for the coil. After a magnetic field generator is used to apply a changing magnetic field to the implant, the coil generates an induced current, and the induced magnetic field generated by the coil due to the flow of the induced current is detected by a magnetic field sensor; or the induced current powers a signal transmitter, and the signal emitted by the signal transmitter is detected by a signal receiver; thus, it can be determined that the closed cavity of the implant leaks. The present invention can be applied to the field of implant monitoring devices.

Description

Technical Field

[0001] The present invention relates to the field of implant monitoring devices, and in particular to implant filling materials and use methods thereof. Background Art

[0002] Implants are medical devices that are implanted in the human body and are in long-term or permanent contact with human tissue. At present, some implants are assembled from multiple parts. For example, dental implants are assembled from implants, bases, central screws, dentures and other parts. Due to assembly requirements, this type of implant has one or more closed cavities inside. If there are gaps between the assembly of the implant parts, liquids such as human tissue fluid or blood containing bacteria can easily penetrate into the closed cavity from the gaps, causing inflammation of the human tissue around the implant, and in severe cases, causing implant failure.

[0003] The existing implant leakage detection scheme is to observe whether the tissue around the implant has inflammation, bone atrophy, damage and other symptoms, and judge whether there is leakage inside the implant based on the symptoms. However, when the tissue around the implant has the above symptoms, it indicates that there is long-term leakage inside the implant and the tissue around the implant has been irreversibly damaged. Summary of the invention

[0004] The purpose of the present invention is to provide an implant filler and a method of using the same to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] An implant filler is applied to a human body implant, wherein the implant is provided with a closed cavity, and the implant filler comprises:

[0007] A coil, the bottom of which is disconnected, the coil is placed in the closed cavity, and the bottom of the coil abuts against the bottom wall of the closed cavity;

[0008] Magnetic field generator;

[0009] Magnetic field sensor;

[0010] After the magnetic field generator is started to apply a magnetic field to the implant, the magnetic field generator is turned off and the magnetic field sensor is started to detect the induced magnetic field generated by the coil.

[0011] The beneficial effects of the present invention are as follows: since the coil is arranged in the closed cavity of the implant, and the disconnected position of the bottom of the coil is against the bottom wall of the closed cavity, when the implant leaks, liquid flows into the closed cavity of the implant, and the liquid acts as a conductor to form a closed loop for the coil. After a magnetic field is applied to the implant by a magnetic field generator, the magnetic field generator is turned off. At this time, the magnetic flux of the coil changes to generate an induced current, which is maintained for a period of time. By detecting the induced magnetic field generated by the induced current flowing in the coil through the magnetic field sensor, it can be determined that the closed cavity of the implant has leaks. There is no need to determine whether the implant has leaks by observing whether the tissues around the implant have symptoms such as inflammation, atrophy, and damage. The micro-permeability of the closed cavity inside the implant can be detected in time, so as to achieve early detection and early treatment, avoid symptoms such as bacterial infection, inflammatory response, and implant failure, and reduce the need for subsequent complex treatments, thereby reducing the economic burden on patients, while reducing the discomfort and pain of patients and improving patient satisfaction.

[0047] 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 in combination with the specific content of the technical solution.

[0048] Reference Figure 1 to Figure 2 As shown, the implant filler of the present invention is made into the following first embodiment:

[0049] The implant filler is applied to a human implant 100 , and a closed cavity 110 is provided inside the implant 100 .

[0050] The implant filling includes a coil 200 , a magnetic field generator 300 , and a magnetic field sensor 400 .

[0051] The coil 200 is disposed in the closed cavity 110 of the implant 100 , and the bottom of the coil 200 is disconnected, so that the bottom of the coil 200 abuts against the bottom wall of the closed cavity 110 .

[0052] The magnetic field generator 300 is used to apply a magnetic field to the implant 100. By turning off the magnetic field generator 300, the magnetic flux of the coil 200 is changed, so that the coil 200 generates an induced current and maintains it for a period of time.

[0053] The magnetic field sensor 400 is used to detect the induced magnetic field generated by the coil 200 due to the flow of the induced current.

[0054] The magnetic field generator 300 is started to apply a magnetic field to the implant 100 , and then the magnetic field generator is turned off and the magnetic field sensor 400 is started to detect the induced magnetic field generated by the coil 200 due to the induced current.

[0055] Since the coil 200 is disposed in the closed cavity 110 of the implant 100, and the disconnected position at the bottom of the coil 200 abuts against the bottom wall of the closed cavity 110, when the implant 100 leaks, liquid flows into the closed cavity 110 of the implant 100, and the liquid acts as a conductor to form a closed loop for the coil 200.

[0056] After the magnetic field generator 300 is used to apply a magnetic field to the implant 100, the magnetic field generator 300 is turned off, and the magnetic flux of the coil 200 is reduced to zero, which generates an induced current and lasts for a period of time.

[0057] Then, the magnetic field generator 300 is turned off, and the induced magnetic field generated by the coil 200 due to the flow of the induced current is detected by the magnetic field sensor 400, so that it can be determined that the closed cavity 110 of the implant 100 has leakage.

[0058] There is no need to judge whether the implant 100 is leaking by observing whether the tissues around the implant 100 are inflamed, atrophied, damaged or other symptoms. The micro-permeability of the closed cavity 110 inside the implant 100 can be detected in time to achieve early detection and early treatment, avoid symptoms such as bacterial infection, inflammatory response, and implant 100 failure, reduce the need for subsequent complex treatments, thereby reducing the economic burden on patients, while reducing patients' discomfort and pain and improving patient satisfaction.

[0059] In some embodiments, the implant filler is further provided with a water absorbent 700, which is provided at the bottom of the coil 200 and abuts against the bottom wall of the closed cavity 110. The water absorbent 700 is in an insulating state when not absorbing water, so that the bottom of the coil 200 remains disconnected. After the water absorbent 700 absorbs liquid, a large amount of conductive ions exist in the liquid, so that the bottom of the coil 200 is turned on, so that the coil 200 forms a closed loop.

[0060] Liquid leaked into the closed cavity 110 of the implant 100 is absorbed by the absorbent member 700. Even if the total amount of liquid is not enough to completely wet the entire absorbent member 700, the liquid will reduce the insulation performance of the absorbent member 700. Even a small amount of leaked liquid will cause the bottom of the coil 200 to be turned on, thereby improving the accuracy of leakage detection of the implant 100.

[0061] In some embodiments, the water absorbing member 700 is coated or doped with an electrolyte.

[0062] When the liquid that leaks into the closed cavity 110 of the implant 100 adheres to the water absorbent 700, it will dissolve the electrolyte on the water absorbent 700, causing it to release a large amount of conductive ions, thereby further reducing the insulation performance of the water absorbent 700, helping to increase the conductivity of the water absorbent 700, improving the charging efficiency and discharging efficiency of the coil 200, and helping the coil 200 to generate a stronger magnetic field, allowing the magnetic field sensor 400 to more accurately measure the induced magnetic field generated by the coil 200.

[0063] In some embodiments, the implant filler is further provided with an insulating wire 800 , which connects the disconnected position at the bottom of the coil 200 .

[0064] The disconnected position at the bottom of the coil 200 is connected by the insulating wire 800. When the liquid leaking into the closed cavity 110 submerges both ends of the entire insulating wire 800, the disconnected position at the bottom of the coil 200 is connected.

[0065] In some embodiments, the implant filler is further provided with a filling body 900 , which is used to be installed in the closed cavity 110 , and the filling body 900 is connected to the coil 200 so that the bottom of the coil 200 abuts against the closed cavity 110 .

[0066] The filling body 900 is provided to fix the position of the coil 200 in the closed cavity 110 to avoid displacement of the coil 200 inside the closed cavity 110 during the patient's activities and to prevent the disconnected position at the bottom of the coil 200 from detaching from the bottom of the closed cavity 110, so as to ensure that the leaked liquid can conduct the bottom of the coil 200.

[0067] In some embodiments, there are multiple types of coils 200, and the sizes of the multiple coils 200 are different, which leads to different induced currents generated by the coils 200, that is, different types of coils 200 generate different magnetic field strengths due to the induced current. Since some implants 100 are provided with two or more closed cavities 110, the multiple coils 200 are respectively placed in multiple closed cavities 110.

[0068] A plurality of coils 200 are placed in a plurality of closed cavities 110 of the implant 100 respectively, and when the magnetic field is detected by the magnetic field sensor 400: when a certain closed cavity 110 of the implant 100 leaks, the corresponding coil 200 can be found and the corresponding closed cavity 110 can be located by the magnetic field strength measured by the magnetic field sensor 400; when two or more closed cavities 110 of the implant 100 leak, the actual magnetic field strength is measured by the magnetic field sensor 400, and the actual magnetic field strength should be greater than the induced magnetic field strength of each coil 200 alone, and then the actual magnetic field strength is compared with the sum of the induced magnetic field strengths of any two coils 200, or the actual magnetic field strength is compared with the sum of the induced magnetic field strengths of any multiple coils 200, to find the corresponding two or more coils 200 and locate the corresponding closed cavity 110.

[0069] Specifically, refer to Figure 1 to Figure 2 As shown, the implant filler includes two coils 200 , a magnetic field generator 300 , a magnetic field sensor 400 , two water absorbent members 700 , two insulating wires 800 , and a filling body 900 .

[0070] In this embodiment, the implant 100 is an implant, and the implant 100 includes an implant 101, a base 102, a central screw 103, and a denture 104. A mounting hole is set at the top of the implant 101, and a threaded hole is set at the bottom of the mounting hole. The base 102 is provided with an assembly hole that passes through from top to bottom. The bottom of the base 102 is inserted into the mounting hole at the top of the implant 101, and the central screw 103 extends from the assembly hole of the base 102 into the mounting hole of the implant 101 and is threadedly connected to the threaded hole, then the mounting hole of the implant 101 forms a closed cavity 110, and the denture 104 closes the top of the base 102, then the assembly hole of the base 102 forms a closed cavity 110.

[0071] Each coil 200 gradually spirally extends from bottom to top, and the top of the coil 200 is provided with a conductive column extending downward to the bottom, and the bottom of the coil 200 is provided with a disconnected conductive head, and the bottom end of the conductive column and the conductive head are connected by an insulating wire 800, and the insulating wire 800 extends in a horizontal direction.

[0072] A water absorbent 700 is correspondingly arranged at the bottom of each coil 200 . The water absorbent 700 is a water absorbent cotton sheet. The water absorbent 700 is doped with electrolyte. The insulating wire 800 is against the water absorbent 700 , and the outside of the insulating wire 800 is coated with electrolyte.

[0073] The two coils 200 have different dimensions.

[0074] The first coil 200 is arranged in a closed cavity 110 formed by the assembly hole of the base 102, and a cylindrical filling body 900 is installed inside the coil 200. The outer wall of the filling body 900 and the inner wall of the assembly hole limit the coil 200, so that the central axis of the coil 200 is parallel to the axis of the assembly hole, and the bottom of the coil 200 is in contact with the bottom wall of the closed cavity 110 through the insulating wire 800 and the water absorbent member 700. The bottom wall of the closed cavity 110 is the top end surface of the central screw 103.

[0075] The second coil 200 is arranged in the closed cavity 110 formed by the mounting hole of the implant 101. The coil 200 is sleeved on the outside of the screw of the central screw 103 so that the central axis of the coil 200 is parallel to the axis of the mounting hole, and the bottom of the coil 200 is in contact with the bottom wall of the closed cavity 110 through the insulating wire 800 and the water absorbent 700. The bottom wall of the closed cavity 110 is the bottom wall of the mounting hole.

[0076] The magnetic field generator 300 and the magnetic field sensor 400 are arranged on the same mechanism. The magnetic field generator 300 is arranged around the periphery of the magnetic field sensor 400. When the magnetic field generator 300 is started, the magnetic field generator 300 generates a magnetic field. After the magnetic field generator 300 is turned off, the magnetic field sensor 400 is started. The magnetic field sensor 400 is used to measure the magnetic field strength.

[0077] When in use, the magnetic field generator 300 and the magnetic field sensor 400 are placed above the implant 100 , and the magnetic field generator 300 is started, so that the magnetic field generator 300 applies a magnetic field to the two coils 200 .

[0078] When leakage occurs in a closed cavity 110 of the implant 100, the coil 200 is turned on to form a closed loop. After the magnetic field generator 300 is turned off, the coil 200 generates an induced magnetic field due to the flow of induced current. The magnetic field sensor 400 is started to measure the induced magnetic field strength generated by the coil 200. Since the two coils 200 have different sizes, the corresponding coil 200 and the corresponding closed cavity 110 can be determined based on the magnetic field strength.

[0079] When leakage occurs in both closed cavities 110 of the implant 100 and the magnetic field generator 300 is started, the two coils 200 are respectively turned on to form a closed loop. When the magnetic field generator 300 is turned off, the two coils 200 generate an induced magnetic field due to the flow of induced current. The magnetic field strength measured by the started magnetic field sensor 400 is approximately equal to the sum of the induced magnetic field strengths generated by the two coils 200, and it can be determined that leakage occurs in the two closed cavities 110.

[0080] The above-mentioned implant 100 is implanted in the patient's lower jaw. When the implant 100 is implanted in the patient's upper jaw, the bottom of the coil 200 located in the assembly hole of the base 102 should abut against the inner wall of the closed assembly hole of the denture 104, and the bottom of the coil 200 located in the mounting hole of the implant 101 should abut against the bottom end surface of the base 102.

[0081] Reference Figure 3 to Figure 4 As shown, the implant filler of the present invention is made into the second embodiment as follows:

[0082] The implant filler is applied to a human implant 100 , and a closed cavity 110 is provided inside the implant 100 .

[0083] The implant filler includes a coil 200 , a magnetic field generator 300 , a signal transmitter 500 , and a signal receiver 600 .

[0084] The coil 200 is disposed in the closed cavity 110 of the implant 100 , and the bottom of the coil 200 is disconnected, so that the bottom of the coil 200 abuts against the bottom wall of the closed cavity 110 .

[0085] The magnetic field generator 300 is used to apply a changing magnetic field to the implant 100. In this embodiment, the magnetic field of the coil 200 is changed by changing the magnetic field strength.

[0086] The signal transmitter 500 is electrically connected to the coil 200 , and the induced current generated by the coil 200 supplies power to the signal transmitter 500 , so that the signal transmitter 500 can transmit signals outward.

[0087] The signal receiver 600 is used to receive the signal sent by the signal transmitter 500 .

[0088] Since the coil 200 is disposed in the closed cavity 110 of the implant 100, and the disconnected position at the bottom of the coil 200 abuts against the bottom wall of the closed cavity 110, when the implant 100 leaks, liquid flows into the closed cavity 110 of the implant 100, and the liquid acts as a conductor to form a closed loop for the coil 200.

[0089] After applying a changing magnetic field to the implant 100 using the magnetic field generator 300, the coil 200 will generate an induced current to power the signal transmitter 500. After receiving the signal through the signal receiver 600, it can be determined that the closed cavity 110 of the implant 100 has a leak.

[0090] In some embodiments, the implant filler is further provided with a water absorbent 700, which is provided at the bottom of the coil 200 and abuts against the bottom wall of the closed cavity 110. The water absorbent 700 is in an insulating state when not absorbing water, so that the bottom of the coil 200 remains disconnected. After the water absorbent 700 absorbs liquid, a large amount of conductive ions exist in the liquid, so that the bottom of the coil 200 is turned on, so that the coil 200 forms a closed loop.

[0091] Liquid leaked into the closed cavity 110 of the implant 100 is absorbed by the absorbent member 700. Even if the total amount of liquid is not enough to completely wet the entire absorbent member 700, the liquid will reduce the insulation performance of the absorbent member 700. Even a small amount of leaked liquid will cause the bottom of the coil 200 to be turned on, thereby improving the accuracy of leakage detection of the implant 100.

[0092] In some embodiments, the water absorbing member 700 is coated or doped with an electrolyte.

[0093] When the liquid that leaks into the closed cavity 110 of the implant 100 adheres to the water absorbent 700, it will dissolve the electrolyte on the water absorbent 700, causing it to release a large amount of conductive ions, thereby further reducing the insulation performance of the water absorbent 700, helping to increase the conductivity of the water absorbent 700, and improving the induced current generated by the coil 200, which helps the coil 200 provide sufficient current to the signal transmitter 500 to ensure that the signal transmitter 500 continues to send a signal.

[0094] In some embodiments, the implant filler is further provided with an insulating wire 800 , which connects the disconnected position at the bottom of the coil 200 .

[0095] The disconnected position at the bottom of the coil 200 is connected by the insulating wire 800. When the liquid leaking into the closed cavity 110 submerges both ends of the entire insulating wire 800, the disconnected position at the bottom of the coil 200 is connected.

[0096] In some embodiments, the implant filler is further provided with a filling body 900 , which is used to be installed in the closed cavity 110 , and the filling body 900 is connected to the coil 200 so that the bottom of the coil 200 abuts against the closed cavity 110 .

[0097] The filling body 900 is provided to fix the position of the coil 200 in the closed cavity 110 to avoid displacement of the coil 200 inside the closed cavity 110 during the patient's activities and to prevent the disconnected position at the bottom of the coil 200 from detaching from the bottom of the closed cavity 110, so as to ensure that the leaked liquid can conduct the bottom of the coil 200.

[0098] In some embodiments, there are multiple coils 200, and a signal transmitter 500 is electrically connected to the top of each coil 200. The multiple signal transmitters 500 are of different models so that the signals emitted by the multiple signal transmitters 500 are different. The multiple coils 200 and the multiple signal transmitters 500 are respectively installed in the multiple closed cavities 110 of the implant 100.

[0099] Part of the implant 100 is provided with a plurality of closed cavities 110. Since the signals emitted by the signal transmitter 500 in each closed cavity 110 are different, the corresponding one or more signal transmitters 500 can be determined according to the signal type received by the signal receiver 600, and then it can be determined whether the corresponding closed cavity 110 has leakage.

[0100] Specifically, refer to Figure 3 to Figure 4 As shown, the implant filler includes two coils 200 , a magnetic field generator 300 , two signal transmitters 500 , a signal receiver 600 , two water absorbent parts 700 , two insulating wires 800 , and a filling body 900 .

[0101] In this embodiment, the implant 100 is an implant, and the implant 100 includes an implant 101, a base 102, a central screw 103, and a denture 104. A mounting hole is set at the top of the implant 101, and a threaded hole is set at the bottom of the mounting hole. The base 102 is provided with an assembly hole that passes through from top to bottom. The bottom of the base 102 is inserted into the mounting hole at the top of the implant 101, and the central screw 103 extends from the assembly hole of the base 102 into the mounting hole of the implant 101 and is threadedly connected to the threaded hole, then the mounting hole of the implant 101 forms a closed cavity 110, and the denture 104 closes the top of the base 102, then the assembly hole of the base 102 forms a closed cavity 110.

[0102] Each coil 200 gradually spirally extends from bottom to top, and the top of the coil 200 is provided with a conductive column extending downward to the bottom, and the bottom of the coil 200 is provided with a disconnected conductive head, and the bottom end of the conductive column and the conductive head are connected by an insulating wire 800, and the insulating wire 800 extends in a horizontal direction.

[0103] A water absorbent 700 is correspondingly arranged at the bottom of each coil 200 . The water absorbent 700 is a water absorbent cotton sheet. The water absorbent 700 is doped with electrolyte. The insulating wire 800 is against the water absorbent 700 , and the outside of the insulating wire 800 is coated with electrolyte.

[0104] The two coils 200 have different dimensions.

[0105] The first coil 200 is arranged in a closed cavity 110 formed by the assembly hole of the base 102, and a cylindrical filling body 900 is installed inside the coil 200. The outer wall of the filling body 900 and the inner wall of the assembly hole limit the coil 200, so that the central axis of the coil 200 is parallel to the axis of the assembly hole, and the bottom of the coil 200 is in contact with the bottom wall of the closed cavity 110 through the insulating wire 800 and the water absorbent member 700. The bottom wall of the closed cavity 110 is the top end surface of the central screw 103.

[0106] The second coil 200 is arranged in the closed cavity 110 formed by the mounting hole of the implant 101. The coil 200 is sleeved on the outside of the screw of the central screw 103 so that the central axis of the coil 200 is parallel to the axis of the mounting hole, and the bottom of the coil 200 is in contact with the bottom wall of the closed cavity 110 through the insulating wire 800 and the water absorbent 700. The bottom wall of the closed cavity 110 is the bottom wall of the mounting hole.

[0107] The signals of the two signal transmitters 500 are different, and the two signal transmitters 500 are electrically connected to the tops of the two coils 200 in a one-to-one correspondence.

[0108] The magnetic field generator 300 and the signal receiver 600 are arranged on the same mechanism. The magnetic field generator 300 is arranged around the periphery of the signal receiver 600. When the magnetic field generator 300 is started, the magnetic field generator 300 generates a magnetic field, the intensity of which changes with time, and the signal receiver 600 is used to receive signals.

[0109] When in use, the magnetic field generator 300 and the signal receiver 600 are placed above the implant 100 , and the magnetic field generator 300 is started, so that the magnetic field generator 300 applies a changing magnetic field to the two coils 200 .

[0110] When leakage occurs in a closed cavity 110 of the implant 100, the coil 200 is turned on to form a closed loop, and the coil 200 generates an induced current. The coil 200 supplies power to the signal transmitter 500, the signal transmitter 500 sends a signal, and the signal receiver 600 receives the signal. The corresponding closed cavity 110 can be determined according to the type of signal.

[0111] When leakage occurs in both closed cavities 110 of the implant 100 and the magnetic field generator 300 is started, the two coils 200 are respectively turned on to form a closed loop, and the two coils 200 supply power to their respective electrically connected signal transmitters 500. The signal receiver 600 receives two types of signals, thereby determining that leakage occurs in the two closed cavities 110.

[0112] The above-mentioned implant 100 is implanted in the patient's lower jaw. When the implant 100 is implanted in the patient's upper jaw, the bottom of the coil 200 located in the assembly hole of the base 102 should abut against the inner wall of the closed assembly hole of the denture 104, and the bottom of the coil 200 located in the mounting hole of the implant 101 should abut against the bottom end surface of the base 102.
