Description

Technical Field

[0001] The present application relates to the field of oral restoration appliances, and in particular to an easily adjustable simple jaw frame. Background Art

[0002] Oral restoration refers to the treatment of oral and maxillofacial soft and hard tissue defects using artificial restorations, and also includes the treatment of periodontal disease and temporomandibular joint disease through restoration. The jaw frame simulates the static and dynamic state of the dentition and upper and lower jaws to analyze whether the restoration is coordinated with the temporomandibular joint-masturbatory muscle-jaw system.

[0003] The jaw frame is mainly composed of the maxillary body, simulated joint structure, mandibular body and other parts. By rotating the maxillary body to open and close the maxillary body and mandibular body, the static and dynamic of the upper and lower jaws can be simulated. However, the weight of the maxillary body is a fixed value, and the pressing force of the maxillary body biting on the mandibular body is also a fixed value. When different simulation requirements are required, the maxillary body needs to be weighted, and then the pressing force of the upper and lower jaws can be adjusted.

[0004] At present, the method of covering the upper jaw with plaster is usually adopted to increase the weight of the upper jaw, and then adjust the pressing force of the upper and lower jaws to simulate the occlusion state of the upper and lower dentures under different pressing forces. However, the method of using plaster for weighting has low accuracy and is difficult to adjust. It is also time-consuming and laborious to remove the solidified plaster later, resulting in the problem of low convenience of using the jaw frame. Utility Model Content

[0005] In order to improve the convenience of using a jaw frame, the present application provides a simple jaw frame that is easy to adjust.

[0006] The present application provides an easily adjustable simple jaw frame adopting the following technical solution:

[0007] A simple and easily adjustable jaw frame comprises a mandibular body, a rotating shaft, a maxillary body and a counterweight assembly, wherein the mandibular body is rotatably arranged on the rotating shaft, the maxillary body is rotatably arranged on the rotating shaft, the counterweight assembly is arranged on the maxillary body and is used for counterweighting the maxillary body, the counterweight assembly comprises a counterweight rod and a counterweight block, the counterweight rod is arranged on the maxillary body, and a plurality of counterweight blocks are detachably arranged on the counterweight rod.

[0008] By adopting the above technical solution, the staff can slide different numbers of counterweights onto the counterweight rod according to needs, so as to counterweight the upper jaw with different weights, and then adjust the pressing force of the upper jaw and the lower jaw. The accuracy of the counterweight is improved by combining counterweights of a certain weight, and the counterweight can be removed from the counterweight rod at any time, and the counterweight of the upper jaw can be adjusted at any time, which effectively improves the convenience of using the jaw frame.

[0009] Optionally, a tension spring is provided on the mandibular body, an eccentric portion is eccentrically provided on the maxillary body, and the tension spring abuts against the eccentric portion.

[0010] By adopting the above technical solution, when the maxillary body rotates, the maxillary body drives the eccentric part to rotate, so that the tension spring abuts against different positions of the eccentric part, so that the maxillary body is pressed tightly against the rotating shaft, thereby increasing the resistance that needs to be overcome for the rotation of the maxillary body, providing a buffer for the rotation of the maxillary body, and improving the problem of violent collision between the upper and lower dentures caused by the excessively fast rotation speed of the maxillary body.

[0011] Optionally, a control rod is slidably provided on the mandibular body, and the tension spring is sleeved on the control rod.

[0012] By adopting the above technical solution, the control rod supports the tension spring, thereby improving the stability of the tension spring during the extension and retraction process.

[0013] Optionally, a notch is provided on the mandibular body, the opening of the notch faces the tension spring, and the rotating shaft rotates to abut against a side wall of the notch.

[0014] By adopting the above technical solution, the staff first installs the maxillary body on the rotating shaft, and then inserts the rotating shaft into the opening of the notch, so that the rotating shaft abuts against the side wall of the notch, and the tension spring abuts against the eccentric part. The tension spring can press the rotating shaft against the side wall of the notch, completing the assembly of the maxillary body and the mandibular body on the rotating shaft, thereby improving the convenience of the staff in assembling the jaw frame.

[0015] Optionally, a control component for controlling the opening and closing angle of the maxillary body is provided on the maxillary body, and the control component includes a mounting plate and a screw-in screw. The mounting plate is provided on the maxillary body, and the screw-in screw is threadedly provided on the mounting plate and is used to abut against the mandibular body.

[0016] By adopting the above technical solution, the staff rotates the screw to make the screw move away from or close to the mounting plate, and then adjusts the distance between the screw and the mandibular body. When the maxillary body rotates away from the mandibular body, the maxillary body drives the screw to move and abut against the mandibular body, thereby controlling the maximum opening and closing angle of the maxillary and mandibular bodies and improving the accuracy of the simulation.

[0017] Optionally, the mandibular body is provided with an arc ruler for measuring the opening and closing angle of the maxillary body.

[0018] By adopting the above technical solution, the staff can directly read the maximum opening and closing angles of the maxillary and mandibular bodies through the arc ruler, thereby improving the convenience of the staff in measuring the opening and closing angles of the maxillary and mandibular bodies.

[0019] Optionally, a stabilizing assembly for balancing the mandibular body is provided on the mandibular body, and the stabilizing assembly includes a stabilizing rod, a stabilizing block and a locking piece. The stabilizing rod is provided on the mandibular body, and a plurality of stabilizing blocks are slidably provided on the stabilizing rod. The locking piece is provided on the stabilizing rod and is used to position the stabilizing block on the stabilizing rod.

[0020] By adopting the above technical solution, the staff will put the stabilizing block on the stabilizing rod, and then lock the stabilizing block to the stabilizing rod through the locking piece, so as to counterweight the mandible and improve the stability of the mandible, thereby effectively improving the accuracy of the occlusion of the maxillary and mandibular bodies.

[0021] Optionally, the locking member comprises a positioning block, and the positioning block is threadedly disposed on the stabilizing rod and abuts against the stabilizing block.

[0022] By adopting the above technical solution, the staff can position the stabilizing block on the stabilizing rod by twisting the locating block so that the locating block presses against the stabilizing block, thereby improving the convenience of the staff in positioning the stabilizing block.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The accuracy of the weight is improved by combining the weight blocks with a certain weight, and the weight blocks can be removed from the weight rod at any time to adjust the weight of the maxillary body at any time, which effectively improves the convenience of using the jaw frame;

[0025] 2. The tension spring abuts against different positions of the eccentric part, increasing the resistance that the maxillary body needs to overcome for rotation, providing a buffer for the rotation of the maxillary body, and improving the problem of violent collision between the upper and lower dentures caused by the excessive rotation speed of the maxillary body;

[0026] 3. When the maxillary body rotates away from the mandibular body, the maxillary body drives the screw rod to move and abut against the mandibular body, so that the maximum opening and closing angle of the maxillary body and the mandibular body can be controlled, thereby improving the accuracy of the simulation.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The embodiment of the present application discloses a simple jaw frame that is easy to adjust.

[0032] Reference Figure 1 The easily adjustable simple jaw frame includes a mandibular body 1, a rotating shaft 2, a maxillary body 3 and a counterweight assembly 4. The mandibular body 1 is rotatably mounted on the rotating shaft 2, the maxillary body 3 is rotatably mounted on the rotating shaft 2, the counterweight assembly 4 is mounted on the rotating shaft 2, and the counterweight assembly 4 is used to counterweight the maxillary body 3.

[0033] Reference Figure 1 The counterweight assembly 4 includes a counterweight rod 41 and a counterweight block 42. The counterweight rod 41 is installed on the mandibular body 1. There are multiple counterweight blocks 42 that can be detachably installed on the counterweight rod 41. In the present embodiment, the counterweight rod 41 is a screw rod, and the counterweight block 42 is a stainless steel disc. The multiple counterweight blocks 42 are divided into multiple groups of specifications with different weights. Screw holes are provided on the counterweight blocks 42. The counterweight blocks 42 are threadedly connected to the counterweight rod 41 through the screw holes. When the staff rotates the counterweight block 42, the counterweight block 42 can slide up and down on the counterweight rod 41, and then the counterweight block 42 can be installed and removed from the counterweight rod 41. The threaded connection between the counterweight block 42 and the counterweight rod 41 can improve the stability of the counterweight block 42 on the counterweight rod 41.

[0034] When it is necessary to simulate the occlusal state of the upper and lower dentures under different compression forces, the staff will install different numbers and specifications of counterweights 42 on the counterweight rod 41, and counterweight the maxillary body 3 with different weights according to the simulation requirements. Then the staff will lift the maxillary body 3 so that the maxillary body 3 is bitten onto the mandibular body 1, and different compression forces of the maxillary body 3 and the mandibular body 1 can be simulated. By combining counterweights 42 of a certain weight, the compression force of the maxillary body 3 and the mandibular body 1 can be adjusted, which is convenient for the staff to control the accuracy of the counterweight of the maxillary body 3. In addition, the staff can remove the counterweight 42 from the counterweight rod 41 or add the counterweight 42 to the counterweight rod 41 at any time, adjust the counterweight of the maxillary body 3 at any time, and can also conveniently remove the counterweight 42, which effectively improves the convenience of using the jaw frame.

[0035] Reference Figure 1 , Figure 2 A stabilizing component 10 is installed on the mandibular body 1, and the stabilizing component 10 is used to counterweight the mandibular body 1. The stabilizing component 10 includes a stabilizing rod 101, a stabilizing block 102 and a locking piece 103. The stabilizing rod 101 is installed on the mandibular body 1, and a plurality of stabilizing blocks 102 are slidably installed on the stabilizing rod 101. The locking piece 103 is installed on the stabilizing rod 101. The locking piece 103 is used to position the stabilizing block 102 on the stabilizing rod 101. The locking piece 103 includes a positioning block 1031, and the positioning block 1031 is threadedly installed on the stabilizing rod 101, and the positioning block 1031 abuts against the stabilizing block 102 away from the mandibular body 1.

[0036] The staff puts multiple stabilizing blocks 102 on the stabilizing rod 101, and then screws the positioning block 1031 onto the stabilizing rod 101, so that the positioning block 1031 moves toward the direction close to the mandibular body 1 and presses against the stabilizing block 102 away from the mandibular body 1. The positioning block 1031 can position the multiple stabilizing blocks 102 on the stabilizing rod 101. At this time, the multiple stabilizing blocks 102 counterweight the mandibular body 1, improve the stability of the mandibular body 1, and improve the position deviation of the mandibular body 1 when the maxillary body 3 bites onto the mandibular body 1, thereby affecting the accuracy of the simulation. In addition, the staff can unscrew the positioning block 1031 from the stabilizing rod 101, and quickly and conveniently adjust the number of stabilizing blocks 102, and then adjust the configuration of the mandibular body 1.

[0037] Reference Figure 1 , Figure 2 A control component 8 is installed on the maxillary body 3, and the control component 8 is used to control the opening and closing angle of the maxillary body 3. The control component 8 includes a mounting plate 81 and a screw-in screw 82. The mounting plate 81 is installed on the maxillary body 3, and the screw-in screw 82 is threadedly arranged on the mounting plate 81. When the maxillary body 3 rotates in a direction away from the mandibular body 1, the screw-in screw 82 abuts against the mandibular body 1.

[0038] The staff member twists the screw-in screw 82 to move the screw-in screw 82 on the mounting plate 81, and adjusts the distance between the end of the screw-in screw 82 extending out of the mounting plate 81 and the mandibular body 1. When the staff member rotates the maxillary body 3 so that the maxillary body 3 moves away from the mandibular body 1, the maxillary body 3 drives the screw-in screw 82 to move, and the screw-in thread can abut against the mandibular body 1, preventing the maxillary body 3 from continuing to rotate away from the mandibular body 1, thereby conveniently and quickly controlling the maximum opening and closing angles of the maxillary body 3 and the mandibular body 1, thereby improving the accuracy of the simulation test.

[0039] Reference Figure 1 , Figure 2A circular arc ruler 9 is installed on the mandibular body 1 , and the circular arc ruler 9 is located between the maxillary body 3 and the mandibular body 1 . The circular arc ruler 9 is used to measure the opening and closing angle of the maxillary body 3 .

[0040] When the staff rotates the maxillary body 3 away from the mandibular body 1, the rotation angle of the maxillary body 3 can be directly read from the arc scale 9, so as to measure the opening and closing angle of the maxillary body 3 and the mandibular body 1, thereby improving the convenience for the staff to measure the opening and closing angle of the maxillary body 3 and the mandibular body 1.

[0041] Reference Figure 1 , Figure 2 A tension spring 5 is installed on the mandibular body 1, and an eccentric portion 6 is installed on the maxillary body 3 coaxially with the rotating shaft 2. The eccentric portion 6 is eccentrically arranged on the maxillary body 3. A control rod 7 is slidably penetrated through the mandibular body 1 along the length direction of the tension spring 5. The control rod 7 abuts against the eccentric portion 6. The tension spring 5 is sleeved on the control rod 7, and one end of the tension spring 5 away from the mandibular body 1 is connected to the control rod 7. In this embodiment, the tension spring 5 always has a tendency to stretch, and when the maxillary body 3 bites into the mandibular body 1, the end of the eccentric portion 6 with the largest diameter abuts against the control rod 7.

[0042] When the maxillary body 3 rotates toward the mandibular body 1 and bites into the mandibular body 1, the maxillary body 3 drives the eccentric part 6 to rotate. During the rotation of the eccentric part 6, the tension spring 5 always drives the control rod 7 to press against the eccentric part 6, so that the mandibular body 1 always presses against the rotating shaft 2, increasing the resistance that needs to be overcome when the maxillary body 3 rotates, and when the maxillary body 3 gradually bites into the mandibular body 1, the control rod 7 presses from the part with smaller diameter of the eccentric part 6 to the part with largest diameter of the eccentric part 6, increasing the compression amount of the tension spring 5, and then increasing the tension spring 5 driving the control rod 7 to press against the eccentric part 6, so that the resistance that needs to be overcome when the maxillary body 3 rotates gradually increases, providing a buffer for the rotation of the maxillary body 3, slowing down the speed of the maxillary body 3 when it bites into the mandibular body 1, and improving the problem of violent collision between the upper and lower dentures caused by the excessive rotation speed of the maxillary body 3. The control rod 7 can also support the tension spring 5 during the extension and contraction process, thereby improving the stability of the tension spring 5 during the extension and contraction process.

[0043] Reference Figure 1 , Figure 2A notch 11 is provided on the mandibular body 1, and the opening of the notch 11 faces the direction of the rope spring, and the rotating shaft 2 rotates and abuts against the side wall of the notch 11. When assembling the jaw frame, the staff first installs the maxillary body 3 on the rotating shaft 2, and then puts the rotating shaft 2 into the notch 11 from the opening of the notch 11 on the mandibular body 1, so that the rotating shaft 2 abuts against the side wall of the notch 11, and the control rod 7 abuts against the eccentric part 6 under the action of the tension spring 5. At this time, the tension spring 5 drives the rotating shaft 2 to abut against the side wall of the notch 11, so that the rotating shaft 2 can be limited in the notch 11, and the assembly of the maxillary body 3 and the mandibular body 1 on the rotating shaft 2 is completed, which improves the convenience of the staff in assembling the jaw frame.

[0044] The implementation principle of the easy-to-adjust simple jaw frame of the present application embodiment is as follows: the staff installs different numbers and specifications of counterweight blocks 42 on the counterweight rod 41, and installs different numbers of stabilizing blocks 102 on the stabilizing rod 101, and accurately balances the maxillary body 3 and the mandibular body 1 according to the requirements of the occlusal state of the upper and lower dentures under different pressing force states, so that the pressing force of the maxillary body 3 and the mandibular body 1 can be adjusted, and the counterweight of the maxillary body 3 and the mandibular body 1 can be adjusted conveniently and quickly, and then the staff The staff member turns the screw-in screw 82 to control the maximum opening and closing angle of the maxillary body 3, and then lifts the maxillary body 3 to make the maxillary body 3 bite onto the mandibular body 1. During the bite, the tension spring 5 cushions the maxillary body 3, thereby improving the problem of violent collision between the upper and lower dentures caused by the excessive rotation speed of the maxillary body 3. Different pressing forces of the maxillary body 3 and the mandibular body 1 can be simulated, thereby effectively improving the convenience of using the jaw frame and improving the accuracy of simulating the occlusal state of the upper and lower dentures under different pressing force states.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
