Description

A headband-type molded sheet clamping and fixing device Technical Field

[0001] This utility model relates to a headband-type molded sheet clamping and fixing device, belonging to the field of oral medical devices. Background Technology

[0002] In the field of oral medicine, prosthodontic treatment is an extremely important medical procedure aimed at restoring the shape, function, and aesthetics of teeth, thereby improving patients' quality of life. In many prosthodontic treatments, such as tooth fillings, caries repair, and restoration of tooth defects, precise fixation and positioning of prosthetic prostheses are crucial steps to ensure treatment success.

[0003] In traditional techniques, the fixation of dental prostheses typically relies on the dentist or nurse holding the prosthesis holder. During treatment, the operator must hold the prosthesis holder throughout the entire process, ensuring the prosthesis is stably positioned around the tooth requiring restoration within the patient's mouth. This demands constant high concentration from the operator to overcome interference from factors such as the patient's oral muscle movements and saliva production, ensuring the prosthesis remains in a stable position.

[0004] Especially when fixing the position of maxillary teeth, due to gravity and the instability of the support point, they are very prone to falling out, shifting, or sagging, obstructing the view and operating space. Therefore, in maxillary tooth restorations, it is usually necessary for the doctor or nurse to hold the restoration piece. When the doctor has a four-handed nurse, the nurse needs to focus on assisting the doctor in accurately fixing the dental restoration piece, ensuring its stability during the complex maxillary tooth positioning process, and preventing it from falling out, shifting, or sagging. At the same time, the nurse also needs to constantly monitor the operating area, promptly clear secretions or debris in the mouth that may affect the view, provide the doctor with a clear operating field, and assist in passing various surgical instruments to ensure the smooth progress of the operation. Without a four-handed nurse, the doctor cannot accurately position the restoration, is prone to being flustered, and may experience poor fit and easy dislodgement of the restoration.

[0005] At the same time, because it requires a four-handed nurse to hold and fix the patient throughout the entire process, it greatly consumes nursing human resources. This means that in dental restoration treatment, at least one nurse is needed to assist the doctor in this operation, which increases labor costs and the investment of medical resources. Summary of the Invention

[0006] The purpose of this invention is to provide a head-mounted molded lens clamping and fixing device to overcome the problems in traditional oral restoration molded lens clamping and fixing methods, which require nurse coordination and cooperation, and doctor manual operation, resulting in inconvenience in adjusting the position of the molded lens, difficulty in precise control, and susceptibility to interference from dynamic factors in the oral cavity, thereby affecting treatment efficiency, restoration accuracy and effect.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a head-mounted molded sheet clamp traction and fixation device, which includes a cap body, a linkage mechanism, a deformable metal strip, and a molded sheet clamp. The cap body is used to be worn on the patient's head. A linkage mechanism that can rotate left and right is provided at the front end of the cap body. The front end of the linkage mechanism is telescopically connected to the deformable metal strip, and the front end of the deformable metal strip is detachably connected to the molded sheet clamp.

[0008] As a further preferred embodiment of this solution, the linkage mechanism includes a vertical rod and a rotating rod, with one end of the vertical rod fixedly connected to the cap body and the other end rotatably connected to the rotating rod.

[0009] As a further preferred embodiment of this solution, a connecting ring is fixedly installed on the outer surface of the cap opening, and the upright is vertically fixed on the connecting ring.

[0010] As a further preferred embodiment of this solution, the rotating rod and the upright are positioned at a 90-degree angle, and the two are rotatably connected by a connecting shaft.

[0011] As a further preferred embodiment of this solution, the front end of the rotating rod has a hollow structure, and one end of the deformable metal strip can be extended and inserted into the hollow part at the front end of the rotating rod and fixed by a fixing mechanism.

[0012] As a further preferred embodiment of this solution, the fixing mechanism includes a through-hole on the top surface of the front end of the rotating rod, a movable block and a clamping assembly that cooperate with the through-hole, the movable block being slidably fitted onto the front end of the rotating rod, and the clamping assembly being disposed on the movable block for passing through the through-hole to clamp and fix the deformable metal strip.

[0013] As a further preferred embodiment of this solution, the clamping assembly includes a threaded bolt, a knob, and a pressure foot. The threaded bolt is mounted on the movable block through a threaded hole, the knob is located at the top of the threaded bolt, and the pressure foot is located at the bottom of the threaded bolt.

[0014] As a further preferred embodiment of this solution, the front free end of the deformable metal strip is provided with a sleeve, and the rear end of the forming piece clamp is provided with a sleeve joint. The deformable metal strip and the forming piece clamp are detachably connected through the sleeve and the sleeve joint.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This device, through the coordinated use of a cap, a vertical rod, a rotatable lever, and a freely retractable deformable metal strip, enables precise control of the distance between the molded clip and the patient's oral cavity. This allows the clip to accurately reach any designated location around the tooth requiring restoration within the mouth. This combination provides dentists with highly flexible and precise clip positioning during dental treatments. Furthermore, the lever can rotate freely around the vertical rod, allowing its free end to be flexibly adjusted in different directions, greatly expanding the device's spatial adjustability and facilitating rapid positioning based on the patient's oral cavity location and treatment needs.

[0023] 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As shown in Figures 1 to 5, a head-mounted molded sheet clamping and fixing device includes a cap body 1. A connecting ring 2 is fixedly installed on the outer surface of the cap opening of the cap body 1, and a vertical rod 3 is fixedly installed on the connecting ring 2. When in use, the cap body 1 is worn on the patient's head, and the connecting ring 2 is positioned on the side of the patient's head above the ear. By controlling the wearing position of the cap body 1, the vertical rod 3 is vertically positioned at the patient's brow. A rotating rod 4 is rotatably installed at the free end of the vertical rod 3 via a connecting shaft 6. The vertical rod 3 and the rotating rod 4 are set at a 90-degree angle. By controlling the rotation of the rotating rod 4, the distribution position of the free end of the rotating rod 4 can be easily adjusted. The end of the rotating rod 4 away from the vertical rod 3 is hollow and has a deformable metal strip 5 telescopically installed. By pulling the deformable metal strip 5 back and forth, the deformable metal strip 5 can be controlled to slide back and forth within the rotating rod 4, thereby controlling the length of the deformable metal strip 5 extending from within the rotating rod 4. The end of the deformable metal strip 5 away from the rotating rod 4 is detachably connected to a molded sheet clamp 8.

[0025] In this embodiment, as shown in Figure 3, the top surface of the rotating rod 4 has a through-hole 40 that connects to the hollow structure inside the rotating rod 4. The through-hole 40 is located near the outer end of the rotating rod 4. A moving block 41 is slidably sleeved on the rotating rod 4. A pressing component 42 is provided on the moving block 41. When in use, the patient lies on the oral treatment bed and puts on the cap 1. At this time, the molding clip 8 needs to be placed in the designated position in the patient's oral cavity. The specific position of the molding clip 8 can be easily adjusted by adjusting the left and right rotation of the rotating rod 4 and adjusting the extension length of the deformable metal strip 5.

[0026] Specifically, the clamping assembly 42 includes a threaded bolt 421 threadedly mounted on the top surface of the movable block 41. The top of the threaded bolt 421 is provided with a knob 422, and the lower end of the threaded bolt 421 is provided with a pressure foot 423. By rotating the knob 422, the threaded bolt 421 can be easily controlled to rotate on the movable block 41 and its height can be adjusted.

[0027] During use, when the position of the deformable metal strip 5 extending outward is adjusted, it is necessary to fix the deformable metal strip 5. At this time, slide the moving block 41 so that the moving block 41 slides to the corresponding position of the through hole 40. Turn the knob 422 so that the threaded bolt 421 moves downward until the pressure foot 423 passes through the through hole 40 and abuts against the deformable metal strip 5. In this way, the pressure foot 423 applies downward pressure to fix the deformable metal strip 5, so that the deformable metal strip 5 is relatively fixed in distribution, so that the deformable metal strip 5 is not affected by the gravity of the molding sheet clamp 8 and its extension length is changed.

[0028] Meanwhile, a sleeve 7 is fixedly installed at the free end of the deformable metal strip 5, and a connector 9 is provided at the rear end of the molding clip 8. The connector 9 drives the molding clip 8 to be detachably sleeved on the sleeve 7. The function of the molding clip 8 is to firmly hold various dental restoration molding pieces. During dental filling, restoration and other treatment operations, it accurately positions and holds the molding piece in the periphery of the tooth to be restored in the patient's oral cavity, providing the doctor with a standard tooth shape mold for subsequent operations. This helps the doctor to shape the restoration that meets the physiological morphology and functional requirements of the tooth, ensuring that the filling material or restoration material can solidify and form according to the expected shape, thereby improving the accuracy and effect of dental restoration treatment.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit the scope of protection of this utility model in any way, and all technical solutions obtained by equivalent substitution or other means fall within the scope of protection of this utility model. Parts not covered by this utility model are the same as or can be implemented using existing technology.
