Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to an implant pin positioning device and its positioning method. Background Technology

[0002] With the development of society and technology, equipment in various fields has been greatly developed. In the dental department, orthodontics is a common problem among teenagers. Orthodontics can correct misaligned teeth and abnormal tooth shape through oral technology. Braces are often used in orthodontic treatment. During the orthodontic process, orthodontists may also use implants in the alveolar bone as needed. Therefore, implant positioning devices are needed to improve the efficiency of medical staff and reduce safety risks.

[0003] A search revealed that publication number CN112915483A, applied for on February 4, 2021, discloses an implant pin positioning device and its positioning method, which solves the problems of inaccurate implant pin positioning, high manufacturing costs, and lack of market promotion value in current clinical practice. The device includes a support column, a cylinder above the support column, and a positioning telescopic device between the support column and the cylinder. A first polygonal prism is rotatably mounted inside the support column. A rotating shaft, sleeved with the first polygonal prism, is rotatably mounted inside the cylinder. The lower end of the rotating shaft is placed inside a sleeve. A cover plate is rotatably fixed at the upper end of the cylinder. The rotating shaft and the cover plate are rotatably fixed via bearings. The rotating shaft has external threads, and a rotatable nut is located inside the cylinder. The rotating shaft and the nut are threadedly connected. Below the nut is a rotating disk that slides vertically inside the cylinder, and the nut and the rotating disk are rotatably connected. A guide shaft is rotatably fixed inside the cylinder. A first circumferential groove is provided on the outer side of the nut, and a first cam is engaged in the first groove. The first cam rotates and presses against the nut.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The above-mentioned implant positioning device fixes the third positioning rod on the second positioning rod during use. However, this method makes the third positioning rod impossible to disassemble. Each time it is used, a series of parts need to be replaced, which wastes resources. At the same time, too many related parts will affect the operation and use of medical staff.

[0006] 2. The above-mentioned implant positioning device fixes the third positioning rod to the second positioning rod during use. However, this method determines the position of the third positioning rod, which means that implantation can only be performed in a specific location in the oral cavity of a specific patient, resulting in a limited range of applications.

[0007] 3. The above-mentioned implant positioning device requires medical staff to manually open the patient's mouth after anesthesia, which increases the workload of medical staff and makes it inconvenient for medical staff to operate and treat the patient. Summary of the Invention

[0008] The purpose of this invention is to provide an implant positioning device and its positioning method. By utilizing the positioning component, the outer wall of the positioning rod can be directly fixed by the protrusion on the inner wall of the limiting rubber pad, thereby limiting the positioning rod. Installation and disassembly are convenient and quick, with high work efficiency and reduced resource waste. At the same time, the adjustment component can be used to adjust the center point of the positioning rod made in different patient safety areas, making it widely applicable. Furthermore, the support component can push open the patient's lips, making it convenient for staff to operate and avoid the need for medical staff to manually open the patient's mouth after anesthesia, thus reducing workload.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] This invention relates to a nail positioning device, comprising a handle, a rotating shell mounted at the top center of the handle, a straight cylinder at the front end of the upper surface of the rotating shell, a first motor mounted at the bottom center of the interior of the rotating shell, and the output shaft of the first motor connected to a rotating shaft via a coupling; an adjustment assembly is located at the rear end of the upper surface of the rotating shell, the adjustment assembly including a fixed frame and a second motor, the second motor being mounted at one edge of the front end face of the fixed frame, the output shaft of the second motor passing through a bearing on the front end face of the fixed frame and connected to a first threaded rod via a coupling; a positioning assembly is located directly above the fixed frame, the positioning assembly including a positioning rod and a locking block, with locking blocks on the outer sides of both sides of the positioning rod; a support assembly is located at the center of the front end face of the rotating shell, the support assembly including an air cylinder and a knob, the knob being located in front of the air cylinder, and a third threaded rod welded to the center of the rear end face of the knob; the fixed frame is fixed to the top of the rotating shell, the second motor drives the first threaded rod to rotate, and the air cylinder is fixed to the front end face of the rotating shell.

[0011] Furthermore, the top of the rotating shaft passes through the bearing on the bottom of the bracket and connects to the mounting plate. A magnetic block is embedded in the center of the bottom of the mounting plate. The implantation nail body is installed directly above the magnetic block. The outer wall of the bracket is fixed to the inner wall of the rotating shell. The implantation nail body is snapped into the inner side of the mounting plate and is attracted to the inside by the magnetic block.

[0012] Furthermore, the other end of the first threaded rod passes through the threaded hole on one side of the front end face of the slide plate and is connected to the bearing on the inner wall of the fixed frame. A limit rod is provided inside the other side of the front end face of the slide plate. A movable frame is installed on the upper surface of the slide plate. The external thread on the outer wall of the first threaded rod is engaged with the internal thread in the threaded hole wall on the end face of the slide plate, which plays a role in transmission. The limit rod can play a role in limiting and assisting the sliding of the slide plate.

[0013] Furthermore, a third motor is installed at the center of one end face of the movable frame. The output shaft of the third motor passes through the bearing on one end face of the movable frame and is connected to the second threaded rod through a coupling. The operation of the third motor drives the second threaded rod to rotate.

[0014] Furthermore, the other end of the second threaded rod passes through the threaded hole on one side of the first moving block and the threaded hole on the other side of the second moving block, and is connected to the bearing on the inner wall of the moving frame. Support blocks are welded to the center of the upper surface of both the first and second moving blocks. An electric telescopic rod is installed at the center of the inclined surface of the support block. Positive and negative threads are respectively provided on both sides of the outer wall of the second threaded rod, and the positive and negative threads are respectively engaged with the internal threads in the wall of the threaded hole on the end face of the first and second moving blocks. Therefore, when the second threaded rod rotates, it will drive the first and second moving blocks to move in opposite directions. The telescopic end of the electric telescopic rod is connected to the bottom of the rotating plate through a hinge.

[0015] Furthermore, a slot is provided at the center of the upper surface of the card block, and a limiting rubber pad is bonded to the inner wall of the slot. A rotating plate is installed in the bearing at the bottom of the card block, and protrusions are provided on both sides of the inner wall of the limiting rubber pad, which can limit the positioning rod. Under the action of the rotating plate, the card block can be rotated.

[0016] Furthermore, the other end of the third threaded rod passes through the threaded hole on the front end face of the air cylinder and is connected to the bearing on the front end face of the rubber plug. The rear end of the upper surface of the air cylinder is provided with a first air pipe. The external thread on the outer wall of the third threaded rod is engaged with the internal thread in the wall of the threaded hole on the end face of the air cylinder, thereby moving and pushing the rubber plug to move.

[0017] Furthermore, the other end of the first trachea is connected to the connecting pipe via a pipe fitting, and the other end of the connecting pipe is connected to the second trachea via a pipe fitting. The pipe fitting serves as a pipe connection.

[0018] Furthermore, the other end of the second trachea is located on the lower surface of the storage frame. An airbag is installed inside the storage frame, and a push plate is installed on the front end face of the airbag. When the gas inside the airbag increases, it pushes out the push plate, thereby opening the patient's mouth.

[0019] The present invention also provides a method for using an implant pin positioning device, the method specifically including the following steps:

[0020] S1: When medical staff use it, they first make a model of the patient's mouth, then determine the implantation point of the implant body in a safe implantation area based on the patient's mouth model and make a mark. Then they bend the positioning rod so that the top of its middle section fits the marked point, and the two ends are bent and inserted into the brackets of the teeth on both sides to complete the making of the positioning rod.

[0021] S2: Next, when implanting the patient's oral cavity, first insert the two sides of the prepared positioning rod into the slots on the two sides of the card block, and the outer wall of the positioning rod will contact the limiting rubber pad on the inner wall of the slot. Since the outer side of the inner wall of the limiting rubber pad is provided with protrusions, it can limit the positioning rod and complete the installation.

[0022] S3: After the positioning rod is installed, place the end of the straight cylinder close to the patient's teeth, then rotate the knob to push the rubber stopper to move, squeezing the gas in the air cylinder so that the gas in the air cylinder enters the air bladder, causing the air bladder to expand and drive the push plate to open outward, and push the patient's lips open.

[0023] S4: After opening the patient's mouth, first activate the second motor through the controller on the handle to drive the sliding plate. Adjust it so that the center point of the positioning rod is at the same point as the tip of the implant body. Then activate the third motor to adjust the distance between the first and second moving blocks, so that the two outer walls of the positioning rod can be squeezed inward and the two ends of the positioning rod can be inserted into the brackets on the patient's teeth. Then, the medical staff can reconfirm by observing whether the safe area of ​​the patient's mouth, the center point of the positioning rod and the implant body are in the same position, so as to reduce safety risks.

[0024] S5: Next, start the electric telescopic rod to move the two sides of the positioning rod outward, so that the positioning rod rotates around the two ends in the bracket as the center, so that the center point of the positioning rod moves out of the implant point of the implant body. Then start the first motor to drive the mounting plate to rotate and screw the implant body into the alveolar bone to complete the implantation.

[0025] The present invention has the following beneficial effects:

[0026] 1. This invention, through the setting of a positioning component, allows medical personnel to first create a model of the patient's oral cavity. Then, based on the patient's oral cavity model, the implantation point of the implant body is determined and marked within a safe implantation area. Next, the positioning rod is bent so that its middle tip aligns with the marked point, while both ends are bent and inserted into the brackets of the teeth on both sides, thus completing the positioning rod fabrication. Then, during implantation, the two sides of the fabricated positioning rod are inserted into the slots on the two side blocks, and the outer wall of the positioning rod contacts the limiting rubber pad on the inner wall of the slot. Because the outer sides of the inner walls of the limiting rubber pad have protrusions, the positioning rod is effectively limited, completing the installation. For disassembly, the positioning rod is simply pulled out from the limiting rubber pad. This method is convenient, quick, and efficient, while reducing resource waste. It solves the problem of the aforementioned implant positioning device, where the third positioning rod is fixed to the second positioning rod during use, making the third positioning rod impossible to remove. This requires replacing a series of parts each time, wasting resources, and the excessive number of components affects the operation and use by medical personnel.

[0027] 2. This invention, through the setting of an adjustment component, after opening the patient's mouth, firstly activates the second motor via the controller on the handle. The output shaft of the second motor rotates, driving the first threaded rod to rotate via a coupling. The external thread on the outer wall of the first threaded rod engages with the internal thread in the threaded hole wall on the end face of the slide plate. Therefore, when the first threaded rod rotates, it drives the slide plate to move under the action of the thread, causing the slide plate to move forward or backward with the assistance of the limiting rod on the other side. By adjustment, the center point of the positioning rod is aligned with the tip of the implant body. Then, the third motor is activated, and the output shaft of the third motor rotates, driving the second threaded rod to rotate via a coupling. Since the outer walls of the second threaded rod are respectively provided with positive and negative threads, and the positive and negative threads engage with the internal threads in the threaded holes on the end faces of the first and second moving blocks, the rotation of the second threaded rod drives the first and second moving blocks to move in opposite directions. First, the first and second moving blocks are moved in opposite directions, thereby squeezing the outer walls of the positioning rod inward. Then, the two ends of the positioning rod are inserted into the patient's mouth. The first and second moving blocks are moved in opposite directions within the bracket on the tooth. Medical staff can then reconfirm the placement by observing whether the patient's oral cavity safety zone, the center point of the positioning rod, and the implant body are in the same position, reducing safety risks. Next, the electric telescopic rod is activated. Due to its tilted design, when the electric telescopic rod retracts, the hinges cause the two sides of the positioning rod to move outwards, causing the positioning rod to rotate around its two ends within the bracket, moving the center point of the positioning rod out of the implant body's placement point. Then, the first motor is activated. The output shaft of the first motor rotates, driving the rotating shaft through the coupling, which in turn rotates the mounting plate and screws the implant body into the alveolar bone, completing the implantation. The device can then be removed. This allows medical staff to adjust the center point of the positioning rod according to the different patient safety zones, making it widely applicable. It solves the problem of the previous implant positioning device, where the third positioning rod was fixed to the second positioning rod, limiting its applicability to a specific location in the patient's mouth.

[0028] 3. This invention, through the setting of a support component, after the positioning rod is installed, places the end of the straight cylinder tightly against the patient's teeth. Then, the knob is rotated, which drives the third threaded rod to rotate. The external thread on the outer wall of the third threaded rod engages with the internal thread in the threaded hole wall on the front end face of the air cylinder. Therefore, when the third threaded rod rotates, it will move inward under the action of the thread, thereby pushing the rubber stopper to move and squeezing the gas in the air cylinder. This allows the gas in the air cylinder to enter the air bladder through the first air tube, connecting tube, and second air tube, causing the air bladder to expand and drive the push plate to open outward. The push plate then pushes open the patient's lips, making it convenient for staff to operate and avoids the need for medical staff to manually open the patient's mouth after anesthesia, which increases the workload. This solves the problem of the above-mentioned implant positioning device requiring medical staff to manually open the patient's mouth after anesthesia, thus increasing the workload of medical staff and making it inconvenient for medical staff to operate and treat the patient.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] Please see Figures 1 to 8 As shown, this invention is a nail positioning device, including a handle 1, a rotating shell 101 mounted at the top center of the handle 1, a straight cylinder 102 provided at the front end of the upper surface of the rotating shell 101, a first motor 103 mounted at the center of the bottom end inside the rotating shell 101, and the output shaft of the first motor 103 connected to a rotating shaft 104 via a coupling; an adjustment assembly 2 is provided at the rear end of the upper surface of the rotating shell 101, the adjustment assembly 2 including a fixed frame 201 and a second motor 202, the second motor 202 mounted at one edge of the front end face of the fixed frame 201, and the output shaft of the second motor 202 passing through a bearing on the front end face of the fixed frame 201 and connected to the first motor 104 via a coupling. A threaded rod 203 is connected; a positioning component 3 is provided directly above the fixed frame 201. The positioning component 3 includes a positioning rod 301 and a locking block 302. Locking blocks 302 are provided on the outer sides of both sides of the positioning rod 301; a support component 4 is provided at the center of the front end face of the rotating shell 101. The support component 4 includes an air cylinder 401 and a knob 402. A knob 402 is provided directly in front of the air cylinder 401. A third threaded rod 403 is welded to the center of the rear end face of the knob 402. The fixed frame 201 is fixed to the top of the rotating shell 101. The second motor 202 drives the first threaded rod 203 to rotate. The air cylinder 401 is fixed to the front end face of the rotating shell 101.

[0042] Among them, such as Figures 1 to 4As shown, the top of the rotating shaft 104 passes through the bearing on the bottom of the bracket 105 and is connected to the mounting plate 106. A magnetic block 107 is embedded in the center of the bottom of the mounting plate 106. The implant nail body 108 is installed directly above the magnetic block 107. The outer wall of the bracket 105 is fixed to the inner wall of the rotating shell 101. The implant nail body 108 is snapped into the inner side of the mounting plate 106 and is attracted to the inside by the magnetic block 107.

[0043] Among them, such as Figure 2 , 5 As shown in Figure 6, the other end of the first threaded rod 203 passes through a threaded hole on one side of the front end face of the slide plate 204 and is connected to a bearing on the inner wall of the fixed frame 201. A limit rod 205 is provided inside the other side of the front end face of the slide plate 204. A movable frame 206 is installed on the upper surface of the slide plate 204. The external thread on the outer wall of the first threaded rod 203 meshes with the internal thread in the threaded hole on the end face of the slide plate 204, which plays a transmission role. The limit rod 205 can limit and assist the sliding of the slide plate 204. A third motor 207 is installed at the center of one side end face of the movable frame 206. The output shaft of the third motor 207 passes through a bearing on one side end face of the movable frame 206 and is connected to the second threaded rod 208 through a coupling. The operation of the third motor 207 drives the second threaded rod 208 to rotate. One end of the first moving block 209 and the second moving block 2010 are connected to the bearing on the inner wall of the moving frame 206 through the threaded holes on one side of the first moving block 209 and the second moving block 2010. Support blocks 2011 are welded to the center of the upper surface of the first moving block 209 and the second moving block 2010. An electric telescopic rod 2012 is installed at the center of the inclined surface of the support block 2011. The outer walls of the second threaded rod 208 are respectively provided with positive threads and negative threads, and the positive threads and negative threads are respectively engaged with the internal threads in the threaded holes on the end faces of the first moving block 209 and the second moving block 2010. Therefore, when the second threaded rod 208 rotates, it will drive the first moving block 209 and the second moving block 2010 to move in opposite directions. The telescopic end of the electric telescopic rod 2012 is connected to the bottom of the rotating plate 305 through a hinge.

[0044] Among them, such as Figures 6 to 7 As shown, a slot 303 is provided at the center of the upper surface of the locking block 302. A limiting rubber pad 304 is bonded to the inner wall of the slot 303. A rotating plate 305 is installed in the bearing at the bottom of the locking block 302. The inner walls on both sides of the limiting rubber pad 304 are provided with protrusions, which can limit the positioning rod 301. Under the action of the rotating plate 305, the locking block 302 can be rotated.

[0045] Among them, such as Figure 2 , 8As shown, the other end of the third threaded rod 403 passes through the threaded hole on the front end face of the air cylinder 401 and is connected to the bearing on the front end face of the rubber plug 404. The rear end of the upper surface of the air cylinder 401 is provided with a first air tube 4011. The external thread on the outer wall of the third threaded rod 403 is engaged with the internal thread in the wall of the threaded hole on the end face of the air cylinder 401, thereby moving and pushing the rubber plug 404. The other end of the first air tube 4011 is connected to the connecting pipe 405 through a pipe joint. The other end of the connecting pipe 405 is connected to the second air tube 4061 through a pipe joint. The pipe joint serves as a pipe connection. The other end of the second air tube 4061 is provided on the lower surface of the storage frame 406. An air bag 407 is installed inside the storage frame 406. A push plate 408 is installed on the front end face of the air bag 407. When the gas in the air bag 407 increases, it pushes out the push plate 408, thereby opening the patient's mouth.

[0046] One specific application of this embodiment is as follows: After powering on and starting the device, when medical personnel use it, they first create a model of the patient's oral cavity. Then, based on the patient's oral cavity model, they determine and mark the implantation point of the implant body 108 within a safe implantation area. Next, they bend the positioning rod 301 so that its middle tip aligns with the marked point, while both ends are bent and inserted into the brackets of the teeth on both sides, thus completing the fabrication of the positioning rod 301. Then, during the implantation of the patient's oral cavity, they first insert the two sides of the fabricated positioning rod 301 into the slots 303 on the two side blocks 302. The outer wall of the positioning rod 301 will contact the limiting rubber pad 304 on the inner wall of the slot 303. Because the outer sides of the inner walls of the limiting rubber pad 304 have protrusions, the positioning rod can be properly positioned. Positioning rod 301 serves as a limit, completing the installation. For disassembly, simply pull positioning rod 301 out of the limiting rubber pad 304. After installing positioning rod 301, align the end of straight cylinder 102 firmly with the patient's teeth. Then, rotate knob 402. Rotation of knob 402 drives the third threaded rod 403 to rotate. The external thread on the outer wall of the third threaded rod 403 engages with the internal thread in the threaded hole on the front end face of the air cylinder 401. Therefore, as the third threaded rod 403 rotates, it moves inward under the action of the thread, thus pushing the rubber stopper 404 and compressing the gas inside the air cylinder 401. This allows the gas inside the air cylinder 401 to enter through the first air pipe 4011, connecting pipe 405, and second air pipe 4061. The airbag 407 is inserted and inflated, causing the push plate 408 to open outwards. The push plate 408 then pushes open the patient's lips. After opening the patient's mouth, the controller on the handle 1 starts the second motor 202. The output shaft of the second motor 202 rotates, driving the first threaded rod 203 to rotate via a coupling. The external thread on the outer wall of the first threaded rod 203 engages with the internal thread in the threaded hole on the end face of the slide plate 204. Therefore, when the first threaded rod 203 rotates, it drives the slide plate 204 to move under the action of the thread. This causes the slide plate 204 to move forward or backward with the assistance of the limiting rod 205 on the other side. By adjustment, the center point of the positioning rod 301 is aligned with the tip of the implant body 108. At the same point, the third motor 207 is then started. The output shaft of the third motor 207 rotates, driving the second threaded rod 208 to rotate via a coupling. Since the outer walls of the second threaded rod 208 are respectively provided with positive and negative threads, and the positive and negative threads are respectively engaged with the internal threads in the threaded holes on the end faces of the first moving block 209 and the second moving block 2010, the rotation of the second threaded rod 208 will drive the first moving block 209 and the second moving block 2010 to move in opposite directions. First, the first moving block 209 and the second moving block 2010 are moved in opposite directions, thereby squeezing the outer walls of the two sides of the positioning rod 301 inward. Then, the two ends of the positioning rod 301 are inserted into the brackets on the patient's teeth.Then, the first moving block 209 and the second moving block 2010 move in opposite directions. Medical staff can then reconfirm the safety by observing whether the patient's oral cavity safety area, the center point of the positioning rod 301, and the implant body 108 are in the same position, reducing potential safety hazards. Next, the electric telescopic rod 2012 is activated. Due to its tilted design, when the electric telescopic rod 2012 retracts, it will cause the two sides of the positioning rod 301 to move outward under the action of the hinge, causing the positioning rod 301 to rotate around its two ends within the bracket, thus moving the center point of the positioning rod 301 out of the implant point of the implant body 108. Then, the first motor 103 is activated. The output shaft of the first motor 103 rotates, driving the rotating shaft 104 to rotate via the coupling, which in turn drives the mounting plate 106 to rotate and screw the implant body 108 into the alveolar bone, completing the implantation. The device can then be removed and can be adjusted to different safe implantation areas.

[0047] The present invention also provides a method for using an implant pin positioning device, the method specifically including the following steps:

[0048] S1: When medical staff use it, they first make a model of the patient's mouth, then determine the implantation point of the implant body 108 in a safe implantation area based on the patient's mouth model and make a mark. Then they bend the positioning rod 301 so that the top of its middle section fits the marked point, while the two ends are bent and inserted into the brackets of the teeth on both sides to complete the making of the positioning rod 301.

[0049] S2: Next, when implanting the patient's oral cavity, first insert the two sides of the prepared positioning rod 301 into the slots 303 on the two sides of the slot 302, and the outer wall of the positioning rod 301 will contact the limiting rubber pad 304 on the inner wall of the slot 303. Since the outer side of the inner wall of the limiting rubber pad 304 is provided with protrusions, it can limit the positioning rod 301, thus completing the installation.

[0050] S3: After the positioning rod 301 is installed, the end of the straight cylinder 102 is pressed against the patient's teeth. Then, the knob 402 is rotated to push the rubber stopper 404 to move, squeezing the gas in the air cylinder 401, so that the gas in the air cylinder 401 enters the air bag 407, causing the air bag 407 to expand and drive the push plate 408 to open outward, and push the lips on the patient's mouth open.

[0051] S4: After opening the patient's mouth, the second motor 202 is activated by the controller on the handle 1 to drive the slide plate 204 to move. The center point of the positioning rod 301 is adjusted to be the same as the tip of the implant body 108. Then, the third motor 207 is activated to adjust the distance between the first moving block 209 and the second moving block 2010, so that the outer walls of both sides of the positioning rod 301 can be squeezed inward and the two ends of the positioning rod 301 are inserted into the brackets on the patient's teeth. Then, the medical staff can observe whether the safe area of ​​the patient's mouth, the center point of the positioning rod 301 and the implant body 108 are in the same position to make a second determination and reduce safety risks.

[0052] S5: Next, start the electric telescopic rod 2012 to move the two sides of the positioning rod 301 outward, so that the positioning rod 301 rotates with the two ends in the bracket as the center, so that the center point of the positioning rod 301 moves out of the implant point of the implant body 108. Then start the first motor 103 to drive the mounting plate 106 to rotate and screw the implant body 108 into the alveolar bone to complete the implantation.

[0053] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
