Description

Technical Field

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

[0002] In dental implant surgery, accurate positioning devices are essential to ensure the success of the operation. During the operation, the doctor needs to use a drill to drill a hole in the gums in order to insert the implant. However, the friction between the drill and the gums will generate a lot of heat, which not only requires more water to dissipate heat, but also causes the patient to spit water frequently, thus prolonging the operation time. Secondly, in order to improve the accuracy of positioning, all drills 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 blocked by the positioning device, which limits the doctor's direct field of view and affects the accuracy and efficiency of the operation. This will not only affect the success rate of dental implants, but may also affect their long-term stability. Summary of the invention

[0021] 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 of the teeth 100 meshing with each other is the maxillofacial surface.

[0022] The handpiece assembly 200 is connected to the implanter, and the handpiece assembly 200 includes a handle 204, a rotor 201, a drill bit 202, and a guide column 205. The handle 204 has a mounting cavity and an airway 203 connected to the mounting cavity. The handle 204 is the part held by the doctor, so that the doctor can stably control the entire implantation process. The interior of the mounting cavity is used to accommodate mechanical components, and the airway 203 is used to transmit gas.

[0023] The rotor 201 is disposed in the installation cavity and rotates under the drive of the gas entering the installation cavity through the air channel 203. The air channel 203 is connected to an external gas source device, providing a power source so that the drill bit 202 can rotate to perform a drilling operation. Specifically, when the compressed gas enters the installation cavity through the air channel 203, the rotor 201 is driven to rotate.

[0024] The drill bit 202 is connected to one end of the rotor 201 so as to move 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, a space is created for implantation.

[0025] The guide column 205 is resettably disposed in the installation cavity and is located at the other end of the rotor 201. The guide column 205 can slide along the axial direction of the installation cavity, and a portion of the column of the guide column 205 always protrudes from the handle 204. The portion of the column of the guide column 205 protruding from the handle 204 can be connected to the guide ring 302 to achieve preliminary positioning, and the guide column 205 can move in the installation cavity and continue to extend into the guide ring 302 to achieve effective connection, thereby also being able to guide the drill bit 202 to accurately align with the predetermined planting position.

[0026] like Figure 1 and Figure 2 As shown, the guide assembly 300 is connected to the mobile phone assembly 200, and the guide assembly 300 includes a fixing plate 301 and a guide ring 302. The fixing plate 301 is sleeved on the tooth 100 to determine the implant position. The fixing plate 301 can be personalized and designed according to the model of the patient's tooth 100 to ensure that it can be firmly fixed on the tooth 100, thereby providing a stable reference point for the implantation of the implant.

[0027] The guide ring 302 is connected to the fixing plate 301 and corresponds to the implant position. The part of the column of the guide column 205 that always protrudes from the handle 204 can be inserted into the guide ring 302 to preliminarily locate the use position of the mobile phone assembly 200, and the gas enters the installation cavity through the airway 203, which further forces the guide column 205 to extend into the guide ring 302. The guide ring 302 can be an annular structure fixed on the fixing plate 301, with a hole in the center to accommodate the guide column 205. The guide ring 302 ensures the precise positioning of the guide column 205 and the drill bit 202, reducing errors during the operation.

[0028] When the present invention is used, the doctor sets the fixing plate 301 on the patient's tooth 100 to ensure that it is firmly fixed in place. The guide ring 302 is connected to the fixing plate 301, and the position of the guide ring 302 corresponds to the predetermined implant position. The mobile phone assembly 200 is connected to the implantation machine.

[0029] Before the mobile phone assembly 200 is started, the protruding portion of the guide column 205 can cooperate with the guide ring 302 to preliminarily locate the use position of the mobile phone assembly 200. After the mobile phone assembly 200 is started, the gas enters the installation cavity through the air channel 203, and the gas pressure in the installation cavity increases, thereby pushing the guide column 205 into the guide ring 302, so that the mobile phone assembly 200 is positioned by the guide assembly 300.

[0030] At the same time, the gas drives the rotor 201 to rotate, and the rotation of the rotor 201 drives the drill bit 202 to rotate to drill holes. That is, the doctor holds the handle 204 to drill holes and implant the implant. After the operation is completed, the guide assembly 300 is removed to complete the dental implant operation.

[0031] In the present invention, the surgical position of the mobile phone assembly 200 can be located by the cooperation of the guide column 205 and the guide ring 302, thereby ensuring that the use position of the drill bit 202 is accurate. In the prior art, the drill bit 202 is usually positioned by directly positioning the guide assembly 300. This method makes the guide assembly 300 contact with the drill bit 202, and more heat is generated between the two due to friction, and more water spraying is required for cooling. However, the present invention does not directly position the drill bit 202, the guide assembly 300 and the drill bit 202 are not in direct contact, and there is no problem of more heat generated between the two due to friction. Therefore, the amount of water sprayed by the present device is less than that used in the prior art (water spraying is used to cool the surgical position and / or the drill bit 202).

[0032] The invention aims to improve the accuracy and efficiency of dental implant surgery. Through precise positioning and a stable operating platform, doctors can perform implant surgery more quickly and safely, while reducing the pain and discomfort of patients. In addition, this device simplifies the surgical process, shortens the operation time, reduces damage to surrounding tissues, and improves the success rate of the operation.

[0033] In one embodiment, if Figure 1 and Figure 6 As shown, the handle 204 includes a grip and a connecting portion, the diameter of the grip decreases in the direction close to the tooth 100, and the diameter of the connecting portion decreases in the direction close to the guide ring 302, so that the handle 204 can better adapt to the space in the oral cavity and provide a stable grip. The airway 203 runs through the grip, and the connecting portion is provided with an installation cavity that runs through from top to bottom to accommodate components such as the rotor 201 and the guide column 205.

[0034] In one embodiment, if Figure 6 and Figure 7 As shown, the installation cavity includes a first chamber 207 and a second chamber 208. The first chamber 207 is provided at one end of the connecting portion and is connected to the air passage 203. The rotor 201 is provided 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 greater than the diameter of the rotor 201 to ensure that the rotor 201 can rotate freely inside the first chamber 207 without being restricted.

[0035] The second chamber 208 is arranged at the other end of the connecting part 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, thereby ensuring that the guide column 205 is close to the rotor 201 when not in operation.

[0036] Among them, one end of the first chamber 207 close to the second chamber 208 is an open structure, and the other end thereof is provided with an air outlet. The second chamber 208 is a hollow structure that is connected from top to bottom, and is connected to the opening structure of the first chamber 207. Because the airway 203 is connected to the first chamber 207, when the gas enters the first chamber 207 from the airway 203, the first chamber 207 is first filled. When the gas in the first chamber 207 increases, the air pressure inside increases, and the gas will enter the second chamber 208, thereby forcing the guide column 205 to move in a direction away from the rotor 201.

[0037] 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 column 205, and part of the column of the guide column 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. The increase in air pressure can not only drive the rotor 201 in the first chamber 207 to rotate, but also force the guide column 205 in the second chamber 208 to move away from the rotor 201, that is, the guide column 205 extends into the guide ring 302.

[0038] In one embodiment, if Figure 6 As shown, a connection hole is provided on the end surface of the first chamber 207, and the connection hole extends in a direction away from the rotor 201 to form a connection cavity, and one end of the drill bit 202 extends into the connection cavity and is detachably connected to the end of the rotor 201 extending into the connection cavity. This method allows for quick switching of different surgical tools without completely disassembling the device, thereby saving surgical time.

[0039] In one embodiment, if Figure 2 As shown, the fixing plate 301 includes a first positioning plate 3011, an arc plate 3012 and a second positioning plate 3013. The edges of the first positioning plate 3011, the arc plate 3012 and the second positioning plate 3013 are all rounded. The rounded structure helps to reduce damage to oral soft tissues and improve patient comfort and safety.

[0040] Specifically, the first positioning plate 3011 is arranged on the jaw surface of the tooth 100, and a avoidance groove is provided in the middle. The arc plate 3012 is connected to the inner wall of the avoidance groove and extends in a direction away from the first positioning plate 3011 to form a tooth implant position. The two second positioning plates 3013 are both arranged on the buccal surface of the tooth 100, and cooperate with the first positioning plate 3011 to form a protection zone, which is used to protect the tooth 100 adjacent to the tooth implant position.

[0041] The present invention can ensure that the implant is implanted in a predetermined precise position through the fixing plate 301, thereby improving the success rate of the operation. The shape of the fixing plate 301 can better adapt to the shape of the tooth 100, and the protection area can protect the adjacent teeth 100 from damage during the operation, thereby reducing the potential risk to the healthy teeth 100.

[0042] 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 installed 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 realized by the connecting sleeve 304, the connecting seat 305 and the connecting rod 303, and the connection is stable and easy to adjust, which is convenient for installation and adjustment.

[0043] In another embodiment, the connecting rod 303 can pass 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 so that the connecting rod 303 can 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 of the teeth 100 on both sides of the implant position. A rubber sleeve is provided on one end of the connecting rod 303 abutting against the jaw surface of the tooth 100, and the rubber sleeve can play a buffering role to avoid damaging the jaw surface of the tooth 100.

[0044] 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, and 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.

[0045] In order to ensure that the guide column 205 can be smoothly inserted into the guide ring 302, the outer diameter of the guide column 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.

[0046] 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.

[0047] The adjustment component 206 of the present invention can adjust the relative position of the guide column 205 and the guide ring 302 to ensure that the two are concentric, thereby improving the accuracy of positioning and ensuring the correct placement of the implant. In addition, the adjustment component 206 can produce a buffering effect, thereby ensuring that the vibration of the mobile phone component 200 is not easily transmitted to the patient, thereby improving the patient's comfort.

[0048] 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, and the airbag and the airway 203 share a gas source.

[0049] The airbag on the outer peripheral wall of the guide column 205 can expand along the radial direction of the rotor 201 to ensure the concentricity between the guide column 205 and the guide ring 302. This method provides an automatic adjustment mechanism to ensure accurate positioning. At the same time, the airbag can also serve as a buffer device to reduce the vibration of the mobile phone assembly 200 during the operation and transmit it to the patient, thereby improving the comfort and safety of the operation.

[0050] 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.

[0051] When the guide post 205 is inserted into the guide ring 302, the arc block can move into the groove when being squeezed, so that the support spring is compressed, and thus does not affect the guide post 205 from entering the guide ring 302. In addition, the support spring always gives the arc block a tendency to approach 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.

[0052] The present invention adjusts the guide column 205 and the guide ring 302 by cooperating with the support spring and the arc block. This structure enables the guide column 205 to adapt to guide rings 302 of different diameters without affecting the positioning effect. In addition, the support spring can be used as a buffer device to reduce the vibration of the mobile phone assembly 200 during the operation and transmit it to the patient, thereby improving the comfort and safety of the operation.

[0053] In summary, during the dental implant surgery, the doctor will conduct a comprehensive oral examination of the patient, including evaluation of the teeth 100 and alveolar bone, to determine the best position for the dental implant. According to the patient's oral condition, a suitable dental implant positioning device is selected, including a mobile phone assembly 200 and a guide assembly 300.

[0054] The fixing plate 301 is mounted on the patient's teeth 100. The fixing plate 301 includes a first positioning plate 3011, an arc plate 3012 and two second positioning plates 3013, which together form a protection zone to protect the adjacent teeth 100. In addition, the guide ring 302 is connected to the fixing plate 301, corresponding to the predetermined implant position. A connecting sleeve 304 is provided on the outer peripheral wall of the guide ring 302, which is connected to the connecting seat 305 on the first positioning plate 3011 through a connecting rod 303 to ensure stable fixation.

[0055] The mobile phone assembly 200 is connected to the planting machine, and a retractable guide column 205 is provided on the upper part of the mobile phone assembly 200. Before the mobile phone assembly 200 is started, due to the low internal wind pressure, the tension spring makes the guide column 205 in a retracted state. At this time, part of the column of the guide column 205 still protrudes from the handle 204, and the mobile phone assembly 200 is initially positioned by using the protruding part of the column.

[0056] After the mobile phone assembly 200 is started, the gas enters the first chamber 207 through the air, and the pressure in the first chamber 207 increases. The pressure causes the guide column 205 to move away from the second chamber 208, thereby further inserting the guide column 205 into the guide ring 302. In addition, the outer diameter of the guide column 205 is smaller than the inner diameter of the guide ring 302, and the guide column 205 can be smoothly inserted into the guide ring 302.

[0057] In order to improve the accuracy of positioning, an air bag is provided on the outer circumference of the guide column 205. When the mobile phone is started, the air bag will expand radially to complete further positioning and ensure that the guide column 205 is concentric with the guide ring 302. The adjustment component 206 not only improves the positioning accuracy, but also produces a buffering effect with the guide ring 302, reducing the force of the vibration of the mobile phone component 200 transmitted to the patient, and improving the comfort and safety of the operation.

[0058] When the dental implant positioning device is installed, the doctor holds the mobile phone 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.

[0059] During the whole process, the dental implant positioning device realizes efficient, accurate and comfortable dental implant surgery through the cooperation of the retractable guide column 205 and the guide ring 302, and further control of the adjustment component 206. It not only takes into account the actual operation requirements during the operation, improves the success rate of the operation, but also reduces the discomfort of the patient.

[0060] The technical features of the above embodiments may 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.

[0061] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
