Description

Technical Field

[0001] The present invention relates to the technical field of dental medical instruments, in particular to a dental implant positioning device. Background Art

[0002] In dental implant surgery, precise positioning devices are crucial to ensuring the success of the operation. During the operation, the doctor needs to use a drill to drill a hole in the gum to place the implant. However, the friction between the drill bit and the gum generates a large amount of heat, which not only requires more water to dissipate heat, but also causes the patient to spit water frequently, thereby prolonging the operation. Secondly, to improve the accuracy of positioning, all drill bits need to be equipped with positioning devices, which undoubtedly increases the complexity of surgical tools and makes surgical preparation and operation more cumbersome. In addition, the surgical area is often obscured by the positioning device, limiting the doctor's direct field of view and affecting the accuracy and efficiency of the operation. This not only affects the success rate of dental implants, but may also affect their long-term stability. Summary of the Invention

[0003] Based on this, it is necessary to provide a dental implant positioning device to address the problems existing in the current dental implant positioning device.

[0017] A second chamber is provided at the other end of the connecting portion and has an open end. The second chamber is communicated with the interior of the first chamber. The second chamber is provided with the guide column capable of moving along the axial direction of the rotor. A tensioning spring is provided between the guide column and the rotor. The tensioning spring is used to make the guide column tend to approach the rotor.

[0018] Furthermore, a connecting hole is provided on the end surface of the first chamber, and the connecting hole extends in a direction away from the rotor to form a connecting cavity. One end of the drill bit extends into the connecting cavity and is detachably connected to the end of the rotor extending into the connecting cavity.

[0021] an arc-shaped plate connected to the inner wall of the avoidance groove and extending in a direction away from the first positioning plate to form the tooth implant position;

[0022] Two second positioning plates are both arranged on the buccal surface of the teeth and are respectively connected to the first positioning plates to form a protection zone, wherein the protection zone is used to protect the teeth adjacent to the implant position.

[0023] Furthermore, the edges of the first positioning plate, the arc-shaped plate and the second positioning plate are all rounded structures.

[0024] Furthermore, a connecting sleeve is provided on the outer peripheral wall of the guide ring, a connecting seat is mounted on the first positioning plate by screws, and the connecting sleeve and the connecting seat are connected by a connecting rod.

[0025] Furthermore, the diameter of the guide column is smaller than the diameter of the guide ring, and an adjustment component is provided between the outer wall of the guide column and the inner wall of the guide ring.

A groove is provided on the outer wall of the guide column, a support spring is provided in the groove, and an arc block is provided at one end of the support spring away from the guide column. The arc block can move into the groove under external action.

[0028] The beneficial effects of the present invention are:

[0029] The present invention features a simple structural design. A retractable guide post is positioned above the handpiece assembly, and a guide ring secured to the tooth is positioned above the post. Before the handpiece assembly is activated, a portion of the guide post connects to the ring to initially position the handpiece assembly. After the handpiece assembly is activated, internal pressure causes the guide post to extend further into the ring to determine the implant's position.

[0030] Furthermore, an adjustment assembly is positioned between the outer wall of the guide post and the inner wall of the guide ring. When the handpiece is activated, this assembly expands radially, further enhancing positioning. This ensures effective positioning without affecting the guide post's penetration into the guide ring. Furthermore, the adjustment assembly provides a buffering effect, preventing vibrations from the handpiece assembly from being transmitted to the patient, enhancing surgical comfort and safety.

[0043] The embodiment of the present invention provides a dental implant positioning device, which is applied to a tooth 100, such as Figure 1-Figure 5 As shown, the dental implant positioning device includes a mobile phone assembly 200 and a guide assembly 300. The tooth 100 includes an upper incisor 101 and a lower incisor 102. The side of the tooth 100 close to the tongue is the lingual surface, the side of the tooth 100 close to the cheek is the buccal surface, and the side where the teeth 100 mesh with each other is the maxillary surface.

[0044] Handpiece assembly 200 is connected to the implantation machine and includes a handle 204, a rotor 201, a drill bit 202, and a guide post 205. Handle 204 has a mounting cavity and an airway 203 connected to the mounting cavity. Handle 204 is the part the surgeon holds, allowing for stable control of the implantation process. The mounting cavity houses the mechanical components, while airway 203 is used to transmit gas.

[0045] Rotor 201 is located within the mounting cavity and rotates driven by gas entering the cavity through air channel 203. Air channel 203 is connected to an external air source, providing the power source that enables drill bit 202 to rotate and perform the drilling operation. Specifically, compressed gas enters the mounting cavity through air channel 203, driving rotor 201 to rotate.

[0046] The drill bit 202 is connected to one end of the rotor 201 and moves with the rotor 201. The drill bit 202 is a terminal tool directly connected to the rotor 201 and can be any drill bit suitable for dental surgery. Through precise drilling operations, space is created for the implant to be placed.

[0047] The guide post 205 is repositionably disposed within the mounting cavity and is located at the other end of the rotor 201. The guide post 205 can slide axially along the mounting cavity, with a portion of the guide post 205 always protruding from the handle 204. The portion of the guide post 205 protruding from the handle 204 can connect with the guide ring 302 to achieve initial positioning. The guide post 205 can also move within the mounting cavity and continue to extend into the guide ring 302 to achieve effective connection, thereby guiding the drill bit 202 to accurately align with the predetermined implantation position.

[0048] like Figure 1 and Figure 2 As shown, the guide assembly 300 is connected to the handpiece assembly 200 and includes a fixing plate 301 and a guide ring 302. The fixing plate 301 is placed over the tooth 100 to determine the implant's position. The fixing plate 301 can be custom-made, designed based on a model of the patient's tooth 100, to ensure it is securely fixed to the tooth 100, thereby providing a stable reference point for implant placement.

[0049] The guide ring 302 is connected to the fixed plate 301 and corresponds to the implant location. The portion of the guide post 205 that protrudes from the handle 204 can be inserted into the guide ring 302 to initially locate the position of the mobile phone assembly 200. The gas entering the installation cavity through the airway 203 further forces the guide post 205 into the guide ring 302. The guide ring 302 can be an annular structure fixed to the fixed plate 301, with a central hole to accommodate the guide post 205. The guide ring 302 ensures the precise positioning of the guide post 205 and the drill bit 202, reducing errors during the surgery.

[0050] During use, the doctor places the fixing plate 301 over the patient's tooth 100, securing it securely in place. The doctor then connects the guide ring 302 to the fixing plate 301, with the position of the guide ring 302 corresponding to the intended implant location. The doctor then connects the handpiece assembly 200 to the implant machine.

[0051] Before mobile phone assembly 200 is activated, the protruding portion of guide post 205 engages guide ring 302 to initially position mobile phone assembly 200. After mobile phone assembly 200 is activated, air enters the mounting cavity through air passage 203. The air pressure within the mounting cavity increases, pushing guide post 205 into guide ring 302, positioning mobile phone assembly 200 within guide assembly 300.

[0052] At the same time, the gas drives the rotor 201 to rotate, which in turn drives the drill bit 202 to drill a hole. The doctor holds the handle 204 to drill and place the implant. After the procedure is complete, the guide assembly 300 is removed, completing the dental implant procedure.

[0053] In the present invention, the cooperation between the guide post 205 and the guide ring 302 allows the surgical position of the handpiece assembly 200 to be determined, thereby ensuring the accurate positioning of the drill bit 202. In the prior art, the guide assembly 300 is typically used to directly position the drill bit 202. This method causes the guide assembly 300 to contact the drill bit 202, generating a large amount of heat due to friction between the two, and thus requiring a larger amount of water spray for cooling. However, the present invention does not directly position the drill bit 202. The guide assembly 300 and the drill bit 202 do not directly contact each other, eliminating the problem of excessive heat generation due to friction between the two. Therefore, the water spray volume used in this device is less than that used in the prior art (water spray is used to cool the surgical site and / or the drill bit 202).

[0054] This invention aims to improve the precision and efficiency of dental implant surgery. Through precise positioning and a stable operating platform, surgeons can perform implant surgeries more quickly and safely, while reducing pain and discomfort for patients. Furthermore, this device simplifies the surgical process, shortens surgery time, minimizes damage to surrounding tissue, and improves the success rate of the procedure.

[0055] In one embodiment, if Figure 1 and Figure 6 As shown, handle 204 comprises a grip and a connecting portion. The grip's diameter decreases as it approaches the teeth 100, while the connecting portion's diameter decreases as it approaches the guide ring 302. This allows handle 204 to better fit within the oral cavity while providing a stable grip. An airway 203 extends through the grip, and the connecting portion defines a vertically extending mounting cavity for accommodating components such as the rotor 201 and guide post 205.

[0056] In one embodiment, if Figure 6 and Figure 7 As shown, the mounting cavity includes a first chamber 207 and a second chamber 208. The first chamber 207 is located at one end of the connecting portion and is connected to the air channel 203. The rotor 201 is located in the first chamber 207. An air outlet is provided on the end surface of the first chamber 207. The diameter of the first chamber 207 is larger than that of the rotor 201 to ensure that the rotor 201 can rotate freely within the first chamber 207 without being restricted.

[0057] The second chamber 208 is provided at the other end of the connecting portion and has an open end. The second chamber 208 is communicated with the interior of the first chamber 207. A guide column 205 capable of moving along the axial direction of the rotor 201 is provided in the second chamber 208. A tensioning spring is provided between the guide column 205 and the inner wall of the second chamber 208. The tensioning spring is used to make the guide column 205 tend to approach the rotor 201, ensuring that the guide column 205 is close to the rotor 201 when not in operation.

[0058] The first chamber 207 has an open structure at one end near the second chamber 208, and an air outlet at the other end. The second chamber 208 is a hollow structure that runs vertically through the second chamber 208 and is connected to the open structure of the first chamber 207. Because the airway 203 is connected to the first chamber 207, when gas enters the first chamber 207 from the airway 203, it first fills the first chamber 207. As the gas in the first chamber 207 increases, the pressure inside increases, and the gas flows into the second chamber 208, forcing the guide post 205 to move away from the rotor 201.

[0059] One end of the tension spring is connected to the inner wall of the second chamber 208, and the other end is connected to the end surface of the guide post 205. Part of the guide post 205 protrudes from the second chamber 208. When the gas in the air channel 203 enters the first chamber 207, the air pressure in the first chamber 207 increases. This increase in air pressure not only drives the rotor 201 in the first chamber 207 to rotate, but also forces the guide post 205 in the second chamber 208 to move away from the rotor 201, that is, the guide post 205 extends into the guide ring 302.

[0060] In one embodiment, if Figure 6 As shown, a connecting hole is formed on the end surface of the first chamber 207, extending away from the rotor 201 to form a connecting cavity. One end of the drill bit 202 extends into the connecting cavity and is removably connected to the end of the rotor 201 extending into the connecting cavity. This method allows for quick switching between different surgical tools without completely disassembling the device, thus saving surgical time.

[0061] In one embodiment, if Figure 2 As shown, the fixing plate 301 includes a first positioning plate 3011, a curved plate 3012, and a second positioning plate 3013. The edges of the first positioning plate 3011, the curved plate 3012, and the second positioning plate 3013 are all rounded. This rounded structure helps reduce damage to oral soft tissue and improves patient comfort and safety.

[0062] Specifically, a first positioning plate 3011 is positioned on the jaw surface of the tooth 100 and defines a central relief groove. An arcuate plate 3012 connects to the inner wall of the relief groove and extends away from the first positioning plate 3011 to define the implant site. Two second positioning plates 3013 are positioned on the buccal surface of the tooth 100 and cooperate with the first positioning plate 3011 to form a protective zone, protecting the tooth 100 adjacent to the implant site.

[0063] The present invention utilizes a fixing plate 301 to ensure that the implant is placed in the precise, predetermined position, thereby increasing the success rate of the procedure. The shape of the fixing plate 301 can better adapt to the shape of the tooth 100, and the protection zone can protect adjacent teeth 100 from damage during the procedure, reducing potential risks to healthy teeth 100.

[0064] In one embodiment, if Figure 2 As shown, a connecting sleeve 304 is provided on the outer peripheral wall of the guide ring 302, a connecting seat 305 is mounted on the first positioning plate 3011 by screws, and the connecting sleeve 304 and the connecting seat 305 are connected by a connecting rod 303. The connection between the guide ring 302 and the first positioning plate 3011 is achieved by the connecting sleeve 304, the connecting seat 305 and the connecting rod 303. The connection is stable and easy to adjust, making it easy to install and adjust.

[0065] In another embodiment, the connecting rod 303 can extend through the first positioning plate 3011 to abut against the jaw surface of the tooth 100. When the fixing plate 301 is placed on the tooth 100, the connecting rod 303 can be rotated to abut against the jaw surface of the tooth 100, making the guide assembly 300 more stable and overcoming the instability caused by the large height difference between the teeth 100 on both sides of the implant location. A rubber sleeve is provided on the end of the connecting rod 303 that abuts the jaw surface of the tooth 100. The rubber sleeve acts as a buffer to prevent damage to the jaw surface of the tooth 100.

[0066] In one embodiment, if Figure 6 and Figure 7 As shown, the diameter of the guide column 205 is smaller than the diameter of the guide ring 302. An adjustment component 206 is provided between the outer wall of the guide column 205 and the inner wall of the guide ring 302. The adjustment component 206 is used to adjust the position of the guide column 205 so that the two are concentric when the guide column 205 is inserted into the guide ring 302.

[0067] In order to ensure that the guide post 205 can be smoothly inserted into the guide ring 302, the outer diameter of the guide post 205 must be smaller than the inner diameter of the guide ring 302. On this basis, in order to ensure that the accuracy of positioning is not affected, an adjustment component 206 is provided.

[0068] When the mobile phone assembly 200 is started, the adjustment assembly 206 can be pressed against the inner wall of the guide ring 302 to achieve further positioning. While achieving a good positioning effect, it does not affect the guide column 205 extending into the guide ring 302.

[0069] The adjustment assembly 206 of the present invention adjusts the relative position of the guide post 205 and the guide ring 302 to ensure concentricity, thereby improving positioning accuracy and ensuring correct implant placement. Furthermore, the adjustment assembly 206 provides a cushioning effect, thereby preventing vibrations from the handpiece assembly 200 from being transmitted to the patient, thereby improving patient comfort.

[0070] In one embodiment, if Figure 6 and Figure 7 As shown, the adjustment component 206 is an airbag, and an airbag is provided on the outer peripheral wall of the guide column 205. The airbag can be expanded to press between the outer wall of the guide column 205 and the inner wall of the guide ring 302. The airbag and the airway 203 share an air source.

[0071] The airbag on the outer wall of the guide post 205 can expand in the radial direction of the rotor 201 to ensure concentricity between the guide post 205 and the guide ring 302. This method provides an automatic adjustment mechanism to ensure precise positioning. At the same time, the airbag can also serve as a buffer device to reduce the vibration of the handpiece assembly 200 during surgery and improve the comfort and safety of the operation.

[0072] In another embodiment, the adjustment component includes a support spring and an arc block. A groove is opened on the outer wall of the guide column 205, a support spring is arranged in the groove, and an arc block is arranged at one end of the support spring away from the guide column 205. The arc block can move into the groove under the action of the outside world.

[0073] When the guide post 205 is inserted into the guide ring 302, the arc block is squeezed and can move into the groove, compressing the support spring, thereby not hindering the guide post 205 from entering the guide ring 302. In addition, the support spring always gives the arc block a tendency to move closer to the inner wall of the guide ring 302, so that the outer peripheral wall of the arc block presses against the inner wall of the guide ring 302.

[0074] The present invention utilizes a support spring and an arc block to ensure concentricity between the guide post 205 and the guide ring 302. This structure allows the guide post 205 to adapt to guide rings 302 of varying diameters without compromising positioning. Furthermore, the support spring acts as a buffer, reducing vibrations transmitted from the handpiece assembly 200 to the patient during surgery, thereby enhancing surgical comfort and safety.

[0075] In summary, during a dental implant surgery, the doctor will conduct a comprehensive oral examination of the patient, including an assessment of the teeth 100 and alveolar bone, to determine the optimal implant location. Based on the patient's oral condition, the doctor will select an appropriate dental implant positioning device, including a handpiece assembly 200 and a guide assembly 300.

[0076] The fixing plate 301 is mounted on the patient's tooth 100. The fixing plate 301 comprises a first positioning plate 3011, a curved plate 3012, and two second positioning plates 3013, which together form a protective zone to protect adjacent teeth 100. Furthermore, a guide ring 302 is connected to the fixing plate 301, corresponding to the predetermined implant location. A connecting sleeve 304 is provided on the outer wall of the guide ring 302, which connects to the connecting seat 305 on the first positioning plate 3011 via a connecting rod 303 to ensure stable fixation.

[0077] Connect the handset assembly 200 to the planter. A retractable guide post 205 is located on the upper portion of the handset assembly 200. Before the handset assembly 200 is activated, due to the low internal wind pressure, the tension spring forces the guide post 205 to retract. At this point, a portion of the guide post 205 still protrudes from the handle 204, allowing the handset assembly 200 to be initially positioned.

[0078] After mobile phone assembly 200 is powered on, gas flows into first chamber 207, increasing the pressure within first chamber 207. This pressure causes guide post 205 to move away from second chamber 208, further inserting guide post 205 into guide ring 302. Furthermore, the outer diameter of guide post 205 is smaller than the inner diameter of guide ring 302, allowing guide post 205 to be smoothly inserted into guide ring 302.

[0079] To enhance positioning accuracy, an airbag is positioned on the outer circumference of guide post 205. When the handpiece is activated, the airbag expands radially, further aligning guide post 205 and ensuring concentricity with guide ring 302. Adjustment assembly 206 not only enhances positioning accuracy but also creates a buffering effect with guide ring 302, reducing the vibration transmitted from handpiece assembly 200 to the patient and improving surgical comfort and safety.

[0080] After the dental implant positioning device is installed, the doctor holds the handpiece assembly 200, and the guide column 205 is accurately positioned to the predetermined dental implant position under the guidance of the guide ring 302. The rotor 201 rotates under the drive of the gas entering through the airway 203, driving the drill bit 202 to drill.

[0081] Throughout the entire implant placement process, the dental implant positioning device, through the coordination of the retractable guide post 205 and guide ring 302, and further control by the adjustment assembly 206, enables efficient, precise, and comfortable dental implant surgery. This not only takes into account the actual operational requirements during the surgery, improving the success rate of the surgery, but also reduces patient discomfort.

[0082] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
