Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an implant guide plate and a manufacturing method thereof. Background Art

[0002] With the popularization of oral implant technology in clinical practice and the increasing requirements for oral health of people, more and more patients choose implant restoration treatment for missing teeth. Oral implant guidance technology can assist doctors in accurately implanting implants according to pre-determined implant positions and can minimize the risk of accidental damage to adjacent important anatomical structures. The implant guide plate technology is a widely used one in oral implant guidance technology. Through the implant guide plate, doctors can be assisted in more accurately determining the depth and direction of the implant. When using an implant handpiece for drilling, the implant handpiece is likely to collide with the patient's lips during movement, which not only causes inconvenience in operation but also affects the accuracy of the implant operation. In addition, the coolant ejected from the implant handpiece and the blood and saliva in the patient's oral cavity are likely to choke the patient. However, the existing implant guide plates are difficult to timely discharge the coolant ejected from the implant handpiece and the blood and saliva in the patient's oral cavity, which affects the safety of the implant operation process.

[0003] In addition, the existing implant guide plates usually adopt the computer-aided design and manufacturing method, and design and manufacture the implant guide plate based on the patient's CT data. During the process of designing the implant guide plate, various features need to be added to the guide plate model to meet clinical requirements. However, after generating the guide plate model by using the traditional manufacturing method of the implant guide plate, once a certain step needs to be modified, it is necessary to first cancel the operations step by step, return to this step to modify the parameters and then redo them, or start over from the beginning. Therefore, this method is not flexible and convenient enough in operation. Summary of the Invention

That is to say, during the planting operation, the blood, saliva in the patient's oral cavity, and the coolant ejected by the planting handpiece can enter the saliva suction cavity 3 through the saliva suction holes 301. Among them, one end of the guiding tube 4 is communicated with the saliva suction cavity 3, and the other end of the guiding tube 4 is used to be connected with a negative pressure suction device (not shown in the figure).

[0040] The lip shielding mechanism includes a lip baffle 6, and the lip baffle 6 is arranged at a position on the guide plate base body 1 corresponding to the lower part of the planting holes 2. By arranging the lip baffle 6, when the planting handpiece moves to the planting position, it can effectively prevent the planting handpiece from colliding with the patient's lips, thereby ensuring the smooth progress of the planting operation.

[0041] Among them, the lip baffle 6 includes a baffle body 601 and an arc-shaped folded edge 602 arranged on the left and right sides of the baffle body 601. The upper end of the baffle body 601 is connected to the guide plate base 1, and the two arc-shaped folded edges 602 are arranged opposite to each other. Each arc-shaped folded edge 602 is respectively connected to the baffle body 601 with an arc transition, so that a downwardly concave groove structure is formed between the baffle body 601 and the two arc-shaped folded edges 602, so that during the implantation operation, the blood, saliva and coolant in the patient's mouth can flow into the groove of the baffle body 601.

[0042] The implantation guide of the embodiment of the present invention, during the implantation operation, turns on the negative pressure suction device, and then under the suction of the negative pressure suction device, the blood, saliva and cooling liquid in the patient's mouth can be sucked into the saliva suction cavity 3 through the saliva suction hole 301, and the liquid in the saliva suction cavity 3 is promptly discharged through the guide tube 4, effectively preventing the patient from being choked by the blood, saliva and cooling liquid in the patient's mouth, thereby improving the safety of the implantation operation process.

[0043] In some embodiments of the present invention, a water baffle 603 is provided on the baffle body 601 at a position away from the guide plate base 1, and the two ends of the water baffle 603 are respectively connected to the inner side walls of the two arc-shaped folded edges 602. That is, by providing the water baffle 603, the liquid flowing into the groove of the baffle body 601 can be blocked to prevent the liquid from flowing downward from the baffle body 601.

[0044] Among them, a liquid suction chamber 604 is also provided on the baffle body 601, and the liquid suction chamber 604 is arranged on the side of the water baffle 603 facing the guide plate base 1, and the outer wall of the liquid suction chamber 604 is provided with a plurality of liquid suction holes 605, each of which is connected to the liquid suction chamber 604, and the liquid suction chamber 604 is connected to the guide tube 4 through the connecting tube 7. That is, under the suction of the negative pressure aspirator, the liquid in the groove of the baffle body 601 can be sucked into the liquid suction chamber 604 through the liquid suction holes 605, and the liquid in the liquid suction chamber 604 can be timely discharged through the guide tube 4, thereby effectively preventing the accumulation of liquid flowing into the baffle body 601.

[0045] In some embodiments of the present invention, the implant guide plate further includes a tooth expansion mechanism, which includes an expansion base plate 5 and a plurality of expansion bosses 501 arranged on the expansion base plate 5, and the expansion base plate 5 is arranged on the guide base body 1 at a position away from the implant hole 2. That is, the expansion base plate 5 is used to carry the plurality of expansion bosses 501 and is fixed on the guide base body 1, and the expansion bosses 501 are used to resist the upper dentition. That is, by providing a tooth expansion mechanism, it is convenient to expand the patient's mouth during the implantation operation, thereby ensuring that the implantation operation proceeds smoothly.

[0046] Specifically, a plurality of expansion bosses 501 are arranged in sequence along the length direction of the expansion base plate 5, each expansion boss 501 is a long strip structure, each expansion boss 501 is parallel to each other, and the length extension direction of each expansion boss 501 is perpendicular to the length extension direction of the expansion base plate 5. This arrangement of each expansion boss 501 on the expansion base plate 5 is convenient for cooperating with the upper dentition, and then effectively resisting the upper dentition, ensuring the expansion effect on the patient's oral cavity.

[0047] In some embodiments of the present invention, an observation and verification window 8 is provided on the guide plate base 1, and the observation and verification window 8 passes through the guide plate base 1. By providing the observation and verification window 8, after the patient wears the implantation guide, part of the teeth can be exposed through the observation and verification window 8, thereby verifying whether the implantation guide is firmly worn by the patient.

[0048] In some embodiments of the present invention, the implant guide further includes a visual marker connector 9, which is disposed on the guide base 1 at a position corresponding to below the observation and verification window 8, wherein the visual marker connector 9 is provided with a visual marker slot 901 for inserting a visual marker into the visual marker slot 901.

That is, this structural setting mode of the visual mark connector 9 facilitates the pluggable installation of the visual mark.

[0050] Specifically, a raised or recessed text mark 10 is provided on the outer surface of the marking front plate of the visual marking connector 9. The text mark 10 can be used to distinguish different patients and implant guide design versions.

[0051] In some embodiments of the present invention, in order to prevent the patient from wearing the implant guide unsteadily due to problems such as the manufacturing accuracy of the implant guide, the guide base 1 includes a first movable base portion 101 and a second movable base portion 102 extending along the length direction, and the first movable base portion 101 and the second movable base portion 102 are detachably connected. That is, the guide base 1 can be divided into two independently movable first movable base portions 101 and second movable base portions 102, so that the first movable base portion 101 and the second movable base portion 102 can be installed separately on the patient's gums, so that the implant guide can be worn more securely and stably.

[0052] Among them, the length of the first movable base part 101 is greater than that of the second movable base part 102. The planting holes 2, the lip shielding mechanism, the saliva aspiration mechanism, the observation and verification window 8, and the visual marking connecting piece 9 are respectively arranged on the first movable base part 101, and the tooth spreading mechanism is arranged on the second movable base part 102.

[0053] As Figure 2 shown, an embodiment of the present invention further provides a method for manufacturing a planting guide plate for manufacturing the planting guide plate in the above embodiment, including: designing a planting guide plate model based on the nodes of the data stream. The method specifically includes the following steps:

[0054] Generating a guide plate base according to the three-dimensional model of the patient's teeth to form a data node 100 for the initial structure of the model.

[0055] Performing a Boolean operation merge on the tooth spreading mechanism and the three-dimensional model of the initial structure of the model to obtain a data node 200 for the first combined structure of the model.

[0056] Performing a Boolean operation merge on the lip shielding mechanism and the three-dimensional model of the first combined structure of the model to obtain a data node 300 for the second combined structure of the model.

[0057] Performing a Boolean operation merge on the saliva aspiration mechanism and the three-dimensional model of the second combined structure of the model to obtain a data node 400 for the third combined structure of the model.

[0058] Performing a Boolean operation merge on the visual marking connecting piece and the three-dimensional model of the third combined structure of the model to obtain a data node 500 for the fourth combined structure of the model.

[0059] Performing a Boolean operation merge on the text marking and the three-dimensional model of the fourth combined structure of the model to obtain a data node 600 for the fifth combined structure of the model.

[0060] Performing a Boolean operation merge on the planting holes and the three-dimensional model of the fifth combined structure of the model to obtain a data node 700 for the sixth combined structure of the model, and finally forming a planting guide plate model 800.

[0061] Specifically, the process of generating the three-dimensional model of the saliva aspiration mechanism is: performing a Boolean operation merge on the three-dimensional models of the guiding tube, the saliva aspiration cavity, and the saliva aspiration holes to obtain a data node 900 for the saliva aspiration mechanism.

[0062] Among them, each operation of the user when designing the planting guide plate will generate a corresponding node. As Figure 2 shown, the data stream node diagram clearly records all the operation processes. As Figure 2 each square in shows a node, and the finally generated planting guide plate can be adjusted by modifying each node in the node diagram.

[0063] In the above design process, each node can be regarded as a state or a specific operation. On the left side of the node is the input end, which receives a set of inputs; on the right side of the node is the output end, which produces a set of outputs. The nodes are connected by wires, and the data is transmitted from the initial state to the final state like a factory assembly line.

[0064] Starting from generating the guide plate base according to the three-dimensional model of the patient's teeth (as the data node 100 of the initial structure of the model), any operation of adding or deleting features to the model subsequently corresponds to a specific operation node in sequence.

[0065] In some specific nodes, the basic parameters can be modified in the input box within the node. After the modification is completed, the entire model is automatically updated. For example, the wall thickness and diameter of the chamber can be modified in the node of the saliva suction cavity; the content, depth, size of the text, and the concave-convex setting method of the text on the visual marking connector can be modified in the node of the text mark.

[0066] When a certain node needs to be deleted, the corresponding feature in the three-dimensional model will be deleted. Selecting to add a new node and connecting it to the node graph will add the corresponding feature to the three-dimensional model.

[0067] When disconnecting the node wires, position adjustment operations can be performed on some nodes. For example, if it is found that the position of the implant hole is inappropriate, the node wire for the implant hole can be disconnected in the node graph, and the position of the implant hole can be adjusted through the control in the three-dimensional view. After the adjustment is completed, the corresponding node is reconnected to the model data stream to update the implant guide plate model.

[0068] That is to say, the method for manufacturing the implant guide plate according to the embodiment of the present invention uses graphical data flow nodes to record the design operation steps of the implant guide plate, emphasizes the flow of three-dimensional model data, and defines the operation steps as a series of nodes and the connections between the nodes. All operations on the model can be regarded as a combination of nodes and nodes, which not only makes the entire design process of the implant guide plate more flexible and intuitive, saves design time, but also facilitates the modification and adjustment of the implant guide plate model. That is to say, the method for manufacturing the implant guide plate according to the embodiment of the present invention enables the operation steps to be traceable and modifiable when designing a complex implant guide plate, avoiding the problem of cumbersome modification of the three-dimensional model of the implant guide plate existing in the existing design methods.

[0069] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications, or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
