Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to an implantable mobile phone. Background Technology

[0002] Dental implant restoration has become a routine surgical method for tooth loss or edentulism due to its unique advantages. The process involves drilling into the alveolar bone, but the presence of important anatomical structures such as the mandibular canal, mental foramen, and maxillary sinus in the alveolar bone necessitates very precise drilling depth. To improve drilling accuracy, implant handpieces are typically equipped with stop devices. However, in current technology, these stop devices are housed in the dental toolbox, requiring dentists to manually attach them to the drill according to the drilling depth. In special cases, such as when the drilling depth is unsuitable and adjustments are needed, the dentist must first remove the attached stop device from the drill and then readjust it, a cumbersome process. Furthermore, the use of rubber gloves during surgery, often stained with blood, increases the difficulty of removing and replacing the stop device, contaminates the toolbox, and wastes time, thus increasing surgical risks. Utility Model Content

[0003] In view of this, this application provides a planting mobile phone with an integrated stop device. The drilling depth can be adjusted by simply adjusting the rotating component. The stop component is not in contact with the plant throughout the process, making it safe and hygienic.

[0004] This application provides an implant handpiece, including a stop device, the implant handpiece being able to connect to a dental drill for drilling, the dental drill being arranged along the Z-axis, the stop device including a rotating member, the rotating member being provided with a spiral groove;

[0005] A connecting member, the connecting member being connected to the helical groove, and the connecting member being movable along the helical groove; and

[0006] A stop member is provided, which is connected to the connecting member. When the connecting member moves in the spiral groove, the stop member can move linearly along the Z-axis to control the length of the dental drill exposed from the stop device.

[0007] Furthermore, the rotating component includes a mounting portion, the spiral groove is provided on the mounting portion, and the stopping component is a through cylindrical structure, which is sleeved on the outside of the mounting portion.

[0008] Furthermore, it also includes a transmission device. The stop member has a through guide groove along the Z-axis direction. The transmission device passes through the guide groove. When the rotating member is rotated, the transmission device can move linearly relative to the stop member in the guide groove along the Z-axis direction.

[0009] Furthermore, the transmission device includes a first helical gear and a second helical gear that mesh with each other. The first helical gear is connected to the dental drill, and the second helical gear is connected to the drive device. The drive device drives the dental drill to rotate through the first helical gear and the second helical gear. The stop member is sleeved on the first helical gear and the second helical gear.

[0010] Furthermore, it also includes an outer shell, which includes a bottom shell and a side shell. The bottom shell has a first opening, and the side shell has a third opening. The first helical gear and the second helical gear are respectively positioned and installed in the outer shell through the first opening and the third opening.

[0011] Furthermore, it also includes a housing, the stopping member being able to cover the housing, the housing including a bottom shell, the bottom shell having a second opening, the stopping member being able to protrude from the housing through the second opening.

[0012] Furthermore, the bottom shell is provided with n second openings, where n is greater than or equal to 2 and less than or equal to 4. The n second openings are symmetrically distributed outside the dental drill. The stop component includes n baffles, each of which protrudes from its corresponding second opening from the shell.

[0013] Furthermore, the portion of the stop member protruding from the second opening is provided with a scale to indicate the drilling depth.

[0014] Furthermore, the rotating component includes a mounting part, which is a hollow structure with an internal cavity. The spiral groove extends spirally around the outer peripheral surface of the mounting part and is a through groove that connects the cavity to the outside. One end of the connecting component is accommodated in the cavity.

[0015] Furthermore, the width of one end of the connecting member is greater than the width of the spiral groove to prevent the connecting member from coming out of the spiral groove. The mounting part is provided with an opening communicating with the spiral groove, and the connecting member passes through the opening into the spiral groove.

[0016] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0017] This application connects the rotating component and the stop component via a connecting component, forming a linkage mechanism that serves as the stop device for the implant handpiece. By rotating the rotating component, the dentist can drive the stop component to move, thereby adjusting the exposed length of the dental drill and controlling the drilling depth. In this process, the dentist avoids contact with the stop component, reducing the risk of wound infection due to contact. In addition, since the stop device and the implant handpiece are integrated, the process of installing the stop device by the dentist is omitted, and the process of adjusting the drilling depth is simplified, shortening the time required for oral implant restoration surgery and reducing surgical risks.

[0029] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0030] This application discloses an implant handpiece that allows for drilling into the alveolar bone at different depths during oral implant restoration surgery. Figure 1 As shown, the implant handpiece includes a dental drill 1, a housing 2, a stop device 3, a transmission device 4, and a handle 5. The handle 5 is connected to the housing 2, forming a protective shell and support for the implant handpiece. One end of the dental drill 1 is connected to the transmission device 4, and the other end protrudes from the housing 2; the protruding end is used for drilling into the alveolar bone. The stop device 3 is mounted on the housing 2, and the drilling depth of the dental drill 1 is controlled by adjusting the exposed length of the drill 1. Figure 2 This is a schematic diagram of the stop device 3 protruding from the outer shell 2. When the stop device 3 protrudes from the outer shell 2, the exposed length L of the dental drill 1 decreases, and its drilling depth becomes smaller.

[0031] like Figure 3-5 As shown, the stopping device 3 includes a rotating member 31, a connecting member 32, and a stopping member 33. The rotating member 31 includes a rotating cover 311 and a mounting portion 312 connected to each other, with the mounting portion 312 located at the bottom of the rotating cover 311. A spiral groove 3121 is provided on the side of the mounting portion 312. The spiral groove 3121 extends spirally around the surface of the mounting portion 312 along the Z-axis direction, where the Z-axis is the orientation of the dental drill 1. The connecting member 32 connects the rotating member 31 and the stopping member 33, forming a linkage mechanism. When the rotating member 31 is rotated, the stopping member 33 can move accordingly. In this embodiment, the spiral groove 3121 is through-hole, with one end of the connecting member 32 passing through the spiral groove 3121, movably connected to the rotating member 31, and able to move within the spiral groove 3121 without dislodging from it.

[0032] The stop component 33 is a cylindrical structure, sleeved outside the mounting part 312, and the two are connected to each other by the connecting component 32. The other end of the connecting component 32 is connected to the stop component 33 to achieve synchronous movement of the connecting component 32 and the stop component 33. The stop component 33 and the connecting component 32 can be connected by any method that can achieve relative fixation, such as plugging, snapping, bonding, or welding. The stop component 33 is disposed inside the outer shell 2. When the rotating component 31 is rotated, the stop component 33 can protrude from the outer shell 2 to control the drilling depth of the dental drill 1.

[0033] The stopping component 33, as a key component for stopping the dental drill 1, has its shape and installation position affecting the stopping effect. To improve the stopping effect of the stopping component 33, it is designed as a through-tube structure. When the stopping component 33 protrudes from the outer shell 2, it fits over the dental drill 1. The tube-shaped structure can be cylindrical, square, or other shapes. This design allows the stopping component 33 to enclose the dental drill 1, resulting in a large contact area with the alveolar bone and a good stopping effect. In this embodiment, the stopping component 33 is cylindrical, its shape matching the shape of the outer shell 2, thus maximizing the utilization of internal space.

[0034] The transmission device 4 is a crucial component for drilling holes in the implant handpiece, and it is also housed within the outer casing 2. However, since the implant handpiece is used inside the human oral cavity, where space is limited, an excessively large handpiece could obstruct the surgeon's view and affect the surgical procedure. To improve the utilization of the internal space of the implant handpiece, the transmission device 4 is at least partially housed within the stop component 33. Figure 4 and 5 As shown, the transmission device 4 includes a first helical gear 41 and a second helical gear 42 that mesh with each other. The first helical gear 41 is connected to the dental drill 1, and the second helical gear 42 is connected to the drive device (not shown in the figure). The drive device drives the dental drill 1 to rotate through the transmission device 4. In this embodiment, the rotation axes of the first helical gear 41 and the second helical gear 42 are perpendicular to each other. In other embodiments, they may not be perpendicular, and the included angle between their axes may be other angles, such as 100°, 95°, 85°, etc., as long as the drive device can drive the dental drill 1 to rotate. The stop member 33 is covered outside the first helical gear 41 and the second helical gear 42. Here, "cover" means that the first helical gear 41 and the second helical gear 42 are located within the cross-section of the cylindrical structure of the stop member 33. When the stop member 33 moves towards the dental drill 1, the first helical gear 41 and the second helical gear 42 can be accommodated within the stop member 33, greatly improving the utilization rate of the internal space.

[0035] Since the stop component 33 is a moving part, its movement inevitably affects the connection between the transmission device 4 and the external drive device. To solve this problem, the stop component 33 and the transmission device 4 are positioned relative to each other, ensuring that the stop component 33 can protrude from the outer shell 2 without obstructing the installation of the transmission device 4. Specifically, as follows... Figure 3 As shown, the stop component 33 is provided with a guide groove 331 (due to the viewing angle, Figure 3(The full view of guide groove 331 is not shown). Guide groove 331 extends along the Z-axis. Transmission device 4 passes through guide groove 331 and can move relative to it within guide groove 331. When rotating component 31 is rotated, due to the positioning obstruction of transmission device 4, stop component 33 moves downward in a straight line, while transmission device 4 moves upward in a straight line relative to stop component 33 within guide groove 331.

[0036] With the stop device 3 configured as described, when the rotating member 31 rotates, the connecting member 32 connected to it also rotates. Since the stop member 33 is already positioned with the transmission device 4, it cannot rotate, thus driving the connecting member 32 to move within the spiral groove 3121. As the connecting member 32 moves, the stop member 33, which is fixedly connected to it, then moves linearly along the Z-axis. Since the Z-axis is aligned with the length direction of the drill 1, when the stop member 33 moves downward, the length L of the drill 1 protruding from the stop member 33 decreases, thereby adjusting the drilling depth of the drill 1.

[0037] During dental implant restoration, the dentist determines the drilling depth based on a pre-assessed plan and then adjusts the exposed length of the dental drill 1 by rotating the rotating component 31. To facilitate adjustment and control of the exposed length of the dental drill 1, the stop component 33 is also equipped with graduations. During drilling, the dentist holds the implant handpiece to drill into the alveolar bone. As the dental drill 1 rotates, the stop component 33 moves closer and closer to the alveolar bone. When the stop component 33 contacts the alveolar bone, the dental drill 1 can no longer deepen the hole, indicating that the target depth has been reached, and the drilling process is complete. In this process, since the stop component 33 and the dental drill 1 are pre-installed, the dentist only needs to adjust the rotating component 31 to control the drilling depth without needing to touch the stop component 33. This simplifies the adjustment and installation process of the stop device and avoids the risk of infection caused by the dentist touching the stop device. Furthermore, because the stop component 33 moves linearly and does not rotate circumferentially, the graduations on it do not change position due to rotation, making adjustment and observation more convenient.

[0038] The outer casing 2 primarily serves as a supporting frame for the mobile phone, providing support and fixation for the stopping device 3 and the transmission device 4. For example... Figure 1 As shown, the outer casing 2 includes a bottom casing 21 and a side casing 22. A rotating member 31 is rotatably mounted on the side casing 22 and can rotate relative to it. Figure 1 , 5As shown in Figure 6, the bottom shell 21 has a first opening 211 and a second opening 212, and the side shell 22 has a third opening 221. The first opening 211 and the third opening 221 are used to position and install the first helical gear 41 and the second helical gear 42 respectively, so that the transmission device 4 can be installed and positioned inside the outer shell 2. The second opening 212 is used to provide a channel for the stopping component 33 to protrude from the outer shell 2.

[0039] In some embodiments, the dental drill 1 is detachably connected to the first helical gear 41, and the bottom housing 21 is used to support the transmission device 4 and the dental drill 1. However, since the stop member 33 needs to protrude from the outer shell 2 of the bottom housing 21, a second opening 212 is also required on the bottom housing 21, resulting in the bottom housing 21 being divided. If the second opening 212 is not properly positioned, it can easily affect the stable support effect of the bottom housing 21. Figure 8 As shown, in some extreme cases, the first opening 211 is located at the center of the bottom housing 21, and the stop member 33 is arranged in a cylindrical structure around the dental drill 1. To ensure that the stop member 33 can protrude from the outer shell 2, a ring of openings is also required around the first opening 211 of the bottom housing 21. However, in this case, the bottom housing located in the central area cannot be connected to the side housing 22 due to the presence of the second opening 212, and thus cannot achieve a supporting effect.

[0040] To address the aforementioned issues, n second openings 212 are formed on the bottom shell 21. These n second openings 212 are symmetrically arranged outside the first opening 211, allowing the bottom shell in the central region to connect to the side shells through the area between the n second openings 212, thus improving the support effect of the bottom shell. It should be noted that the symmetrical arrangement here does not have to be geometrically symmetrical; as long as the distribution of the second openings 212 is basically uniform, it is sufficient. Correspondingly, to allow the stop member 33 to protrude from the outer shell 2, the bottom of the stop member 33 has a notch design. Specifically, the stop member 33 includes n baffles 332, which are connected to each other to form a cylindrical structure. However, the bottoms of the n baffles 332 are not connected and are separated from each other, forming n through holes in the shape of a "Z" on the side of the stop member 33. The n baffles 332 correspond one-to-one with the n second openings 212. When the stop member 33 moves downward, the n baffles 332 protrude from the outer shell 2 from their corresponding second openings 212.

[0041] The value of n is greater than or equal to 2 and less than or equal to 4. For example... Figure 9As shown, when n is 1, the number of second openings 212 is also 1. In this case, the connection between the central area enclosed by the second openings 212 and the side shell is only on one side, which also presents the problem of unstable connection. As the value of N increases, the number of segments of the stop member 33 increases, the integrity of the stop member 33 deteriorates, and it is prone to deformation during drilling, affecting the drilling accuracy. At the same time, as the value of n increases, the processing difficulty of the bottom shell 21 and the stop member 33 also increases. Therefore, the value of n should not be too large. When the value is less than or equal to 4, the number of segments of the stop member 33 and the number of second openings 212 are relatively limited, which can meet the stable connection of the dental drill 1 and the stopping requirements of the stop member 33, and the processing is relatively easy.

[0042] See Figure 6 and 7 As shown, in this embodiment, n is 2, and there are 2 second openings 212 and 2 baffles 332. Each baffle 332 can protrude from the outer shell 2 through its corresponding second opening 212.

[0043] The rotating member 31 includes a mounting portion 312, which is a hollow structure forming a cavity inside. A spiral groove 3121 is disposed on the side of the mounting portion 312 and communicates with the cavity. One end of the connecting member 32 is accommodated within the cavity. To prevent the connecting member 32 from dislodging from the spiral groove 3121, the width of the end of the connecting member 32 accommodated within the cavity is greater than the width of the spiral groove 3121. In some embodiments, the end of the connecting member 32 that connects to the spiral groove 3121 is a spherical member, the diameter of which is greater than the width of the spiral groove 3121. To facilitate the installation of the connecting member 32 into the spiral groove 3121, the mounting portion 312 is provided with an opening located at the end of the mounting portion 312 and communicating with the spiral groove 3121, allowing the connecting member 32 to enter the spiral groove 3121 through the opening.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
