Description

Technical Field

[0001] The utility model relates to the field of artificial tooth medical equipment, in particular to an implant positioning guide mechanism. Background Art

[0002] The implant positioning guide mechanism usually consists of a positioning plate, a guide sleeve and a fixing screw. The positioning plate is customized according to the patient's oral CT data and can fit closely to the patient's alveolar bone surface. The guide sleeve is provided with a channel that matches the implant diameter to guide the direction and depth of implant implantation. The fixing screw is used to fix the positioning plate to the patient's alveolar bone to ensure the stability of the positioning plate during the entire operation. Before the dental implant surgery, the doctor will design a personalized implant plan based on the patient's oral CT data and determine the implantation position, direction and depth of the implant. Then, the positioning plate and guide sleeve are made according to these parameters. During the operation, the doctor will fix the positioning plate to the patient's alveolar bone, and then put the guide sleeve on the corresponding position of the positioning plate. Next, the doctor can accurately implant the implant to the predetermined position through the channel on the guide sleeve.

[0003] In the current denture implant process, an operator is usually required to firmly press and stabilize the guide sleeve with one hand to ensure that it is precisely aligned with the predetermined drilling position. Maintaining this stability is crucial because it lays the foundation for the subsequent use of the drill to pass through the guide sleeve and accurately drill and expand the alveolar bone. However, this traditional operation method has a significant disadvantage: in order to maintain the stability of the guide sleeve, the operator must continue to apply a stable force. This long-term muscle tension state is not only prone to hand fatigue and soreness, but may also affect the position accuracy of the guide sleeve due to unstable hand strength. In addition, when the operator's non-dominant hand is busy controlling the movement of the drill and performing delicate drilling operations, the steady force continuously applied by the dominant hand will further increase the difficulty and complexity of the operation. This situation not only reduces the convenience and efficiency of the operation, but more importantly, it may cause a slight deviation of the guide sleeve due to hand fatigue and instability. This deviation is not allowed in delicate oral surgery because it may seriously affect the accuracy and effectiveness of the operation. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an implant positioning guide mechanism to solve the technical problem that continuous and stable force causes the operator's hands to become sore, reducing the convenience of operation, and may even cause the guide sleeve to shift in position due to hand fatigue, affecting the accuracy of the surgery.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an implant positioning guide mechanism, comprising a positioning body and a rear groove positioning piece, the positioning body and the rear groove positioning piece are both provided with an outer sleeve and a fixing column, an inner sleeve is provided on the inner side of the outer sleeve, a guide assembly is provided inside the inner sleeve, the guide assembly comprises a guide block, a first groove is provided on the outer surface of the guide block, a second groove is provided on the inner wall of the inner sleeve, an annular retaining spring is provided inside the first groove and the second groove, a first mounting groove is provided on the surface of the inner sleeve, a second mounting groove is provided on the surface of the outer sleeve, and a through hole is provided at the center axis of the guide block.

[0006] By adopting the above technical solution and utilizing the expansion force of the annular retaining spring, we can achieve automatic installation and fixation of the guide block and the inner sleeve, replacing the traditional method that requires the operator to manually assist in pressing the guide block. This means that during the operation, the doctor no longer needs to continuously apply a stable force to the guide block, thereby reducing the doctor's workload.

[0007] Furthermore, the guide block is engaged with the inner sleeve through the first clamping groove, the annular clamping spring and the second clamping groove.

[0008] By adopting the above technical solution, a firm connection between the guide block and the inner sleeve is achieved, ensuring the stability and accuracy of the guide block during the operation, and the surgical effect will not be affected due to loosening or displacement.

[0009] Furthermore, a handle is provided on one side of the annular retaining spring, and the handle is used to provide a support point for the user to act on the annular retaining spring.

[0010] By adopting the above technical solution, a clear and stable support point is provided for the user. During the operation, the user can accurately control the contraction and expansion of the annular retaining spring by holding the handle, thereby ensuring that the guide block can be accurately installed in the inner sleeve.

[0011] Furthermore, the outer bushing is fixedly connected to the inner bushing, and the first mounting groove is located opposite to the second mounting groove.

[0012] By adopting the above technical solution, the stability and reliability of the entire positioning and guiding structure are ensured. During the operation, this fixed connection can effectively prevent the relative movement between the inner sleeve and the outer sleeve, thereby ensuring the precise position of the positioning body and the guiding assembly.

[0013] Furthermore, the first mounting groove and the second mounting groove are used to clamp and position the annular retaining ring, and the first mounting groove and the second mounting groove are in a "T"-shaped structure.

[0014] By adopting the above technical solution, the annular retaining spring can be stably installed between the guide block and the inner bushing, thereby ensuring the connection strength and stability between them.

[0015] Furthermore, bolts are provided inside the fixing column for positioning the main body and the rear groove positioning piece to engage with the patient's alveolar bone.

[0016] By adopting the above technical solution, the positioning body and the posterior groove positioning piece can be firmly engaged with the patient's alveolar bone. The tightening effect of the bolts ensures the stability of the positioning body and the posterior groove positioning piece during the operation, and will not affect the surgical effect due to loosening or displacement.

[0017] Furthermore, a fixing mechanism is disposed on the outer side of the positioning body, and the fixing mechanism is used to provide additional fixing force for the positioning body, the posterior alveolar positioning piece and the patient's alveolar bone.

[0018] By adopting the above technical solution, additional fixing force is provided between the positioning body and the posterior socket positioning piece and the patient's alveolar bone, thereby enhancing the stability of the entire positioning system and ensuring that the positioning body and the posterior socket positioning piece can always remain in the predetermined position during the operation and will not be displaced due to external factors such as movement in the oral cavity, saliva, etc.

[0019] Furthermore, the fixing mechanism includes a first support frame and a second support frame, and a torsion shaft is arranged between the first support frame and the second support frame.

[0020] By adopting the above technical solution, the positioning body and the posterior socket positioning plate are more firmly connected to the patient's alveolar bone. This additional fixing force helps prevent positioning deviation or loosening due to various factors during the operation, thereby improving the accuracy and reliability of the operation.

[0021] Furthermore, the first support frame abuts against the positioning body, and the second support frame abuts against the patient's mandible.

[0022] By adopting the above technical solution, the stability of the positioning body during the operation is ensured. This abutment effect effectively prevents the positioning body from moving or deviating when subjected to external force or movement inside the oral cavity, providing a reliable basis for subsequent surgical operations.

[0023] Furthermore, support plates are provided on the first support frame and the second support frame, and a gasket is provided between the second support frame and the mandible, and the material of the gasket is rubber.

[0024] By adopting the above technical solution, the contact area with the patient's oral tissue can be increased, providing a more stable support effect, helping to disperse the pressure applied to the patient's mouth, reducing discomfort, and improving stability during the operation.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model uses the expansion force of the annular circlip through the guide assembly to complete the installation and fixation of the guide block and the inner sleeve. This improvement significantly simplifies the surgical process. In traditional operations, the operator needs to continue to use his hands to assist in pressing the guide block, which not only increases the complexity of the operation, but also may cause operational errors due to hand fatigue. By using the annular circlip, we have successfully eliminated this cumbersome step, making the installation process faster and more efficient. At the same time, it also significantly improves the convenience of using the guide assembly. Since the operator is no longer required to continuously apply a stable force, the doctor can focus more on other key steps during the operation, such as drilling and implanting the implant, which not only reduces the doctor's workload, but also helps to improve the accuracy and success rate of the operation;

[0027] 2. The utility model sets a fixing mechanism and utilizes the torque shaft to generate a force on the first support frame and the second support frame, thereby effectively increasing the contact strength between the positioning body and the alveolar bone. The enhanced contact strength ensures that the positioning body can be more firmly fixed in a predetermined position during the operation and will not move or deviate due to activities inside the oral cavity or external interference. At the same time, increasing the contact strength between the positioning body and the alveolar bone can further improve the position stability of the positioning body. When the positioning body is stably fixed on the alveolar bone, the doctor can perform the operation more accurately, reducing the surgical risks caused by inaccurate positioning.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0035] An implant positioning guide mechanism, such as Figure 1-Figure 4 As shown, it includes a positioning body 1 and a rear groove positioning piece 2, the positioning body 1 and the rear groove positioning piece 2 are both provided with an outer bushing 3 and a fixing column 4, the inner side of the outer bushing 3 is provided with an inner bushing 5, the inner part of the inner bushing 5 is provided with a guide assembly 6, the guide assembly 6 includes a guide block 601, the outer surface of the guide block 601 is provided with a first groove 602, the inner wall of the inner bushing 5 is provided with a second groove 605, the first groove 602 and the second groove 605 are provided with an annular retaining spring 603, the surface of the inner bushing 5 is provided with a first mounting groove 606, the surface of the outer bushing 3 is provided with a second mounting groove 607, and a through hole 608 is provided at the central axis of the guide block 601. By utilizing the expansion force of the annular retaining spring 603, we can The guide block 601 and the inner sleeve 5 are automatically installed and fixed, which replaces the traditional method that requires the operator to manually assist in pressing the guide block 601. This means that during the operation, the doctor no longer needs to continuously apply a stable force to the guide block 601, thereby reducing the doctor's workload. At the same time, this new installation method not only improves the ease of use of the guide assembly 6, but also helps to reduce possible errors that may occur during manual operation. Since the manual pressing operation requires high skills and experience from the operator, there are certain risks in the operation process. By using the automatic installation and fixing method of the annular retaining spring 603, we can reduce this risk and improve the accuracy and reliability of the operation.

[0036] See also Figure 3 , Figure 4 The guide block 601 is engaged with the inner sleeve 5 through the first slot 602, the annular retaining spring 603, and the second slot 605, thereby achieving a firm connection between the guide block 601 and the inner sleeve 5, ensuring the stability and accuracy of the guide block during the operation, and will not affect the surgical effect due to loosening or displacement. At the same time, it also simplifies the surgical operation steps. The doctor only needs to insert the guide block 601 into the inner sleeve 5 and automatically engage it through the expansion force of the annular retaining spring 603 without complicated adjustment or fixation. This not only saves operation time, but also reduces the difficulty of operation, making the surgical process more efficient and convenient.

[0037] See also Figure 3 , Figure 4 A handle 604 is provided on one side of the annular retaining spring 603. The handle 604 is used to provide a support point for the user to apply the annular retaining spring 603, which provides the user with a clear and stable support point. During the operation, the user can accurately control the contraction and expansion of the annular retaining spring 603 by holding the handle 604, thereby ensuring that the guide block 601 can be accurately installed in the inner sleeve 5. At the same time, the presence of the handle 604 also enhances the comfort and convenience of operation. The user can apply force more easily and reduce the possibility of hand fatigue and discomfort. In addition, since the handle 604 provides stable support, the user can operate more confidently, thereby improving the efficiency and accuracy of the operation.

[0038] See also Figure 1 , Figure 3 , Figure 4 The outer sleeve 3 is fixedly connected to the inner sleeve 5, and the first mounting groove 606 and the second mounting groove 607 are relative to each other, ensuring the stability and reliability of the entire positioning and guiding structure. During the operation, this fixed connection can effectively prevent the relative movement between the inner sleeve 5 and the outer sleeve 3, thereby ensuring the precise position of the positioning body 1 and the guide assembly 6. At the same time, the structure in which the first mounting groove 606 and the second mounting groove 607 are relative to each other enables the annular retaining spring 603 to be smoothly and accurately placed in these two mounting grooves. This relative position relationship not only simplifies the installation process, but also improves the fixing effect of the annular retaining spring 603, and further enhances the connection stability between the guide block 601 and the inner sleeve 5.

[0039] See also Figure 3 , Figure 4 The first mounting groove 606 and the second mounting groove 607 are used to clamp and position the annular retaining spring 603. The first mounting groove 606 and the second mounting groove 607 are in a "T"-shaped structure, so that the annular retaining spring 603 can be firmly installed between the guide block 601 and the inner sleeve 5, ensuring the connection strength and stability between them. At the same time, the first mounting groove 606 and the second mounting groove 607 are in a "T"-shaped structure. This special shape increases the contact area with the annular retaining spring 603 and provides better support and positioning effects. This structure makes the annular retaining spring 603 not easy to fall off or shift when subjected to external force, thereby ensuring the reliability and durability of the entire guide assembly 6.

[0040] See also Figure 1 , Figure 2A bolt is arranged inside the fixing column 4, which is used to engage the positioning body 1 and the posterior groove positioning piece 2 with the patient's alveolar bone, so that the positioning body 1 and the posterior groove positioning piece 2 can be firmly engaged with the patient's alveolar bone. The tightening effect of the bolt ensures the stability of the positioning body and the posterior groove positioning piece during the operation, and will not affect the surgical effect due to loosening or displacement. At the same time, the adjustment function of the bolt also allows the doctor to accurately adjust the position and angle of the positioning body 1 and the posterior groove positioning piece 2 according to the patient's alveolar bone morphology and surgical needs. This flexibility helps to achieve a more personalized surgical plan and improve the accuracy and success rate of the operation. Embodiment 2:

[0041] See also Figure 1 , Figure 2 A fixing mechanism 7 is arranged on the outer side of the positioning body 1, and the fixing mechanism 7 is used to provide an additional fixing force between the positioning body 1, the posterior groove positioning piece 2 and the patient's alveolar bone, and provides an additional fixing force between the positioning body 1 and the posterior groove positioning piece 2 and the patient's alveolar bone, thereby enhancing the stability of the entire positioning system, ensuring that the positioning body and the posterior groove positioning piece can always remain in a predetermined position during the operation, and will not be shifted due to external factors such as movement in the oral cavity, saliva, etc. At the same time, the existence of the fixing mechanism 7 also shares the fixing pressure that was originally borne only by the positioning body 1 and the posterior groove positioning piece 2, thereby reducing their burden. This sharing effect helps to extend the service life of the positioning body 1 and the posterior groove positioning piece 2, and also reduces the risk of deformation due to long-term excessive pressure.

[0042] See also Figure 1 , Figure 2 The fixing mechanism 7 includes a first support frame 701 and a second support frame 702. A torque shaft 703 is arranged between the first support frame 701 and the second support frame 702 to ensure that the positioning body 1 and the posterior groove positioning plate 2 are more firmly connected to the patient's alveolar bone. This additional fixing force helps to prevent positioning deviation or loosening due to various factors during the operation, thereby improving the accuracy and reliability of the operation. At the same time, the fixing mechanism 7 also takes into account the ease and comfort of operation. The doctor can easily adjust the position and strength of the fixing mechanism 7 to adapt to the alveolar bone morphology and surgical needs of different patients.

[0043] See also Figure 1 , Figure 2The first support frame 701 abuts against the positioning body 1, and the second support frame 702 abuts against the patient's mandible, ensuring the stability of the positioning body 1 during the operation. This abutment effectively prevents the positioning body 1 from moving or deflecting when subjected to external force or movement inside the oral cavity, providing a reliable basis for subsequent surgical operations. At the same time, the second support frame 702 abuts against the patient's mandible, further enhancing the supporting effect of the entire fixing mechanism 7. Through close contact with the mandible, the second support frame 702 can disperse various forces during the operation to a larger area, reducing pressure on local tissues and improving patient comfort.

[0044] See also Figure 1 , Figure 2 A support sheet 704 is provided on the first support frame 701 and the second support frame 702, and a gasket 705 is provided between the second support frame 702 and the mandible. The material of the gasket 705 is rubber, which can increase the contact area with the patient's oral tissue, provide a more stable support effect, and help to disperse the pressure applied to the patient's oral cavity, reduce discomfort, and improve stability during the operation. At the same time, the gasket 705 provided between the second support frame 702 and the mandible is made of rubber material, has good elasticity and buffering performance, and the rubber gasket 705 can effectively protect the patient's mandible, improve comfort, and protect the mandible from damage.

[0045] The implementation principle of the utility model is as follows: first, the positioning body 1 and the rear groove positioning piece 2 are engaged with the alveolar bone of the patient through the fixing column 4 and the bolt, and then, the handle 604 is pinched by hand, so that the annular retaining spring 603 is retracted into the interior of the first retaining groove 602, and the guide block 601 is inserted into the interior of the inner sleeve 5, and at the same time, one side of the annular retaining spring 603 is placed into the interior of the first installation groove 606 and the second installation groove 607, and then, the force on the annular retaining spring 603 is released, and the expansion force of the annular retaining spring 603 is utilized to complete the installation and fixation of the guide block 601 and the inner sleeve 5, and this structural form replaces the auxiliary pressing operation of the guide block 601 by the operator in the traditional operation form, and the operator is exempted from applying a continuous and stable force to the guide block 601, thereby improving the convenience of use of the guide assembly 6, and further reducing the possible mistakes in the manual pressing operation process;

[0046] First, the operator applies pressure to the support plate 704 with his hands, causing the first support frame 701 and the second support frame 702 to rotate through the torque shaft 703 until the first support frame 701 abuts against the positioning body 1 and the second support frame 702 abuts against the mandible, and then releases the force on the support plate 704. The force of the torque shaft 703 on the first support frame 701 and the second support frame 702 is used to increase the abutment force between the positioning body 1 and the alveolar bone, thereby further improving the position stability of the positioning body 1.

[0047] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
