Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a dynamic navigation positioning device. Background Technology

[0002] In oral surgeries (such as dental implants and surgical procedures), dynamic navigation technology relies on high-precision patient positioning tracking. A dynamic navigation positioner is a device that uses a fixed assembly to connect an infrared reference plate and is fixed inside the patient's mouth, forming a stable optical information relationship with the optical tracking system and the handpiece positioner. Meanwhile, occlusal pad mouth openers assist patients in opening their mouths, thereby reducing muscle tension and temporomandibular joint involvement. Clinically, they are often used for longer surgeries and for patients who cannot open their mouths for extended periods.

[0003] Currently, fixation devices are often attached to the patient's mouth using temporary crown materials. These are prone to loosening or falling off during surgery, directly affecting the positioning accuracy of the navigation system and the progress of the surgery. Furthermore, complex surgeries are lengthy, and most patients cannot maintain a wide mouth opening for extended periods, which can hinder the surgeon's operation. Prolonged mouth opening can also cause muscle fatigue and stiffness, easily leading to temporomandibular joint discomfort. Therefore, dynamic navigation positioning devices must consider the patient's ease of biting. Utility Model Content

[0004] This application provides a dynamic navigation positioning device, which solves the problems of existing technology where the fixation device is easy to loosen or fall off during surgery, and patients are prone to muscle fatigue and stiffness due to prolonged mouth opening. It achieves the technical effect of stabilizing the fixation device and facilitating the patient's biting, and can also relieve muscle fatigue and stiffness caused by prolonged mouth opening.

[0005] This utility model provides a dynamic navigation position locator, including a fixing device, a connector, an infrared reference plate, and an occlusal pad; the two ends of the connector are respectively connected to the fixing device and the infrared reference plate; one side of the fixing device fits against the oral cavity, and the other side of the fixing device is engaged with the occlusal pad; the side of the occlusal pad away from the oral cavity fits against the teeth or gums.

[0006] In one possible implementation, the fixing device has a mounting groove; the occlusive pad has a protrusion; the protrusion is slidably connected to the mounting groove, and the occlusive pad slides within the mounting groove of the fixing device via the protrusion.

[0007] In one possible implementation, the occlusal pad has an occlusal groove on the side away from the fixing device, and the occlusal groove fits against the tooth or the gum.

[0008] In one possible implementation, the dynamic navigation positioner further includes a sling; the end of the occlusal pad furthest from the oral cavity is connected to the sling, which is configured to assist in removing the occlusal pad from the oral cavity using a tool.

[0009] In one possible implementation, the mounting groove is a dovetail groove, and the protrusion engages with the dovetail groove.

[0010] In one possible implementation, the bite pad is made of soft silicone.

[0011] One or more technical solutions provided in this application have at least the following technical effects:

[0012] This utility model embodiment employs a dynamic navigation positioning device, including a fixing device, a connector, an infrared reference plate, and an occlusal pad. The connector has the fixing device and the infrared reference plate connected to its two ends respectively. One side of the fixing device fits against the oral cavity, and the other side engages with the occlusal pad. The side of the occlusal pad away from the oral cavity fits against the teeth or gums. A temporary crown material is used to fix the fixing device in the patient's mouth, and the occlusion of the gums or teeth reliably installs the fixing device in the oral cavity, preventing it from falling out. Furthermore, the occlusal pad supports the teeth or gums, reducing muscle stiffness and discomfort when the patient maintains an open mouth for extended periods, providing better operating space for the surgeon and improving surgical efficiency. This application solves the problems of existing technologies where the fixing device easily loosens or falls out during surgery, and where prolonged mouth opening easily causes muscle fatigue and stiffness. It achieves the technical effects of a stable fixing device and convenient occlusion for the patient, and can alleviate muscle fatigue and stiffness caused by prolonged mouth opening.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0020] This utility model embodiment provides a dynamic navigation location locator, such as... Figure 1-3 As shown, it includes a fixing device 1, a connector 2, an infrared reference plate 3, and an occlusal pad 4; the two ends of the connector 2 are respectively connected to the fixing device 1 and the infrared reference plate 3; one side of the fixing device 1 fits against the oral cavity, and the other side of the fixing device 1 is engaged with the occlusal pad 4; the side of the occlusal pad 4 away from the oral cavity fits against the teeth or gums.

[0021] For example, the Dekel dynamic navigation system consists of a host unit, a display, an infrared tracking and positioning system, a locator, a mobile phone clamp, a reference device, a connecting device, a fixing device 1, and a registration device. Doctors can observe the surgical process in real time through the system, improving the accuracy and safety of the surgery. Because the surgical path and operation steps are precisely planned, the surgical trauma is relatively small, resulting in faster patient recovery.

[0022] For example, connector 2 can be configured as a telescopic structure, specifically, it includes an outer tube and an inner rod, the inner rod being screwed into the outer tube by threads, and the size of connector 2 can be adjusted by rotating the threads to adapt to the oral cavity space of different patients.

[0023] For example, the infrared reference plate 3 is provided with multiple regularly arranged reflective markers. The distribution of the markers matches the optical tracking module of the dynamic navigation system, which is used to locate the three-dimensional spatial coordinates inside the oral cavity in real time.

[0024] For example, the fixation device 1 is made of medical-grade resin, and its side surface that fits into the oral cavity has anti-slip texture to enhance friction with the oral mucosa, thereby preventing the fixation device 1 from shifting during the operation.

[0025] In the embodiments of this application, such as Figure 1-3 As shown, the fixing device 1 has an installation groove 11; the biting pad 4 has a protrusion 43; the protrusion 43 is slidably connected to the installation groove 11, and the biting pad 4 slides in the installation groove 11 of the fixing device 1 through the protrusion 43.

[0026] For example, the bite pad 4 has a pressure sensor array in the bite groove 41. The sensors are connected to an external display terminal to monitor the distribution of bite force in real time and feed it back to the navigation system.

[0027] For example, in practical applications, medical staff need to first select a suitable connector 2 according to the tooth position. After the connector 2 is installed with the fixation device 1, a temporary crown material is used to fix the fixation device 1 in the patient's mouth. Finally, the occlusal pad 4 is placed in the mounting slot 11 of the fixation device 1. The occlusal pad 4 placed in the mounting slot 11 allows the fixation device 1 to be more reliably fixed in the patient's mouth, thereby preventing the fixation device 1 from falling off. On the other hand, the occlusal pad 4 can support the teeth or gums, thereby reducing muscle stiffness and discomfort when the patient keeps their mouth open for a long time, providing doctors with better operating space and improving surgical efficiency.

[0028] In the embodiments of this application, such as Figure 1 As shown, the occlusal pad 4 has an occlusal groove 41 on the side away from the fixing device 1, and the occlusal groove 41 fits against the teeth or gums.

[0029] For example, during use, the protrusion 43 of the occlusal pad 4 engages with the occlusal groove 41 of the fixation device 1, the occlusal pad 4 is manually pushed to the target position, and the patient uses their teeth or gums to fix the occlusal pad 4.

[0030] In the embodiments of this application, such as Figure 1 and Figure 2As shown, it also includes a ring 42; the end of the occlusal pad 4 away from the oral cavity is connected to the ring 42, which is configured to assist in removing the occlusal pad 4 from the oral cavity using a tool.

[0031] For example, when healthcare workers need to remove the occlusal pad 4 from the fixation device 1, they can hook the hanging ring 42 with the hook and pull the occlusal pad 4 out of the mouth.

[0032] In the embodiments of this application, such as Figure 1-3 As shown, the mounting groove 11 is a dovetail groove, and the protrusion 43 mates with the dovetail groove.

[0033] For example, the dovetail groove design can increase the stability between the occlusal pad 4 and the fixation device 1, preventing the occlusal pad 4 from falling off during the operation.

[0034] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the bite pad 4 is made of soft silicone.

[0035] For example, soft silicone materials have strong elastic deformation capabilities, which can reduce pressure damage to the gums and improve patient fit and comfort.

[0036] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0037] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
