Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more particularly to an oral dynamic navigation positioning plate fixer. Background Art

[0002] The endodontic dynamic navigation system utilizes 3D medical image visualization, registration, and spatial positioning technologies to plan the ideal surgical path and dynamically guide the direction, angle, and depth of surgery in real time, enabling precise and accurate endodontic procedures such as pulpotomy, bone fenestration, and apical resection. Computer-assisted navigation technology improves surgical accuracy, narrows the gap caused by clinical inexperience, and shortens surgical time.

[0003] The identification and positioning portion of the endodontic dynamic navigation system uses an upper sensor to identify the position of the positioning plate to determine orientation. The positioning plate holder securely affixes the locator to the dental arch within the mouth before surgery, enabling the navigation system to identify the real-time position of the surgical area through algorithms, which plays a crucial role in surgical accuracy and outcome.

[0004] The positioning plate fixer is used to fix the positioning plate in the dynamic navigation system on the opposite side of the affected tooth, so that the positioning plate can be stably retained during the operation to ensure accurate dynamic navigation positioning. The fixator requires a reasonable morphological design and can stably fix the positioning plate during the operation without displacement, blocking the surgical field, or hindering the operation.

[0005] The original retainer is made of plastic and is disposable. Before the operation, dental self-curing resin is used to fix the retainer to the contralateral dental arch.

[0006] The original retainer has some significant disadvantages:

[0007] 1. It is for one-time use and needs to be broken and disassembled after each use. The price of a set is about 200 yuan, and the cost of use is relatively high.

[0008] 2. Dental self-curing resin is required to cure the connection between the original retainer and the human teeth. This has the following problems: the dental water in the self-curing resin has a certain pungent odor, which some patients find difficult to accept; the self-curing resin takes a long time to cure, about 10 minutes, and requires a long preoperative preparation time; the self-curing resin generates heat during the curing process, which makes the patient uncomfortable and may burn the periodontal soft tissue.

[0009] Therefore, how to provide an oral dynamic navigation positioning plate fixture that can be reused and avoids the use of self-curing resin and is easy to place quickly is a problem that technicians in this field urgently need to solve. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-3 The embodiment of the utility model discloses an oral dynamic navigation positioning plate fixator, comprising: a bow portion 1, a body portion 2 and a sleeve 3.

[0030] There are two bodies 2, one end of each body 2 is connected to the open end of the arch 1 respectively, and each body 2 is provided with a through hole 4; the through holes 4 on the two bodies 2 are preferably symmetrically arranged. The arrangement of the through holes 4 facilitates the rapid placement of the oral dynamic navigation positioning plate fixator by clamps, eliminating the need for traditional fixators in the prior art to be connected by self-curing resin curing and the need to wait for the self-curing resin to cure. The oral dynamic navigation positioning plate fixator of the utility model greatly reduces the preoperative preparation time during the placement process.

[0031] A sleeve 3 is fixed to one of the body parts 2 and is provided with a threaded hole 5. The sleeve 3 is used to fix the dynamic navigation locator. Specifically, depending on whether the oral dynamic navigation fixator is to be fixed on the left or right side of the mouth, the sleeve 3 is selected to be installed on the body part 2 outside the tooth to enable the oral dynamic navigation positioning plate fixator to be worn on the outside of the tooth. Preferably, the sleeve 3 has a hexagonal cross-section. The sleeve 3 with a hexagonal cross-section can prevent the extension rod of the locator from rotating when fixing the extension rod. After the extension rod is inserted into the sleeve 3, the oral dynamic navigation positioning plate fixator is fixed by installing an auxiliary screw in the threaded hole 5.

[0032] The top of the arch 1 is higher than the plane of the body 2, providing a clamping force between the two bodies 2, securing them to the inside and outside of the teeth. The height of the arch 1 facilitates placement of the oral dynamic navigation positioning plate fixture and prevents interference between the arch 1 and the teeth.

[0033] It should be noted that the oral dynamic navigation positioning plate fixer of the present invention is connected to the body 2 for matching the inner and outer sides of the teeth at both ends of the bow 1. The bow 1 can provide clamping force to the body 2, thereby fixing the oral dynamic navigation positioning plate fixer on the teeth, making it convenient to fix the dynamic navigation locator on the sleeve 3 on the body 2, so as to solve the problem in the prior art that the dynamic navigation locator needs to be fixed by self-curing resin, thereby avoiding the irritation and potential thermal damage to the patient caused by the self-curing resin.

[0034] According to some embodiments of the present invention, the arch 1 and the body 2 are integrally formed. The integrally formed arch 1 and body 2 can enhance the strength of the oral dynamic navigation positioning plate holder.

[0035] To address the high cost of existing single-use retainers, which require breaking and disassembling after each use, and cost around 200 yuan per set, the present invention provides an oral dynamic navigation positioning plate retainer with both the arch 1 and body 2 made of metal. This metal material allows for reuse after autoclaving, is more stable than plastic, and reduces costs.

[0036] According to some embodiments of the present invention, the inner side of the body 2 has a curved surface adapted to the tooth surface. The setting of the curved surface can improve the wearing comfort of the oral dynamic navigation positioning plate retainer.

[0037] According to some embodiments of the present invention, a rounded and blunt sawtooth protrusion 6 is provided on the inner side of the body 2. In this way, the rounded and blunt sawtooth protrusion 6 can clamp the tooth surface at multiple points to improve the fixing performance.

[0038] According to some embodiments of the present invention, the inner side of the body 2 matches at least two teeth, thereby improving the wearing stability of the oral dynamic navigation positioning plate retainer.
