Description

Technical Field

[0001] The utility model relates to the technical field of dental film photography in stomatology, in particular to a portable dental film photography fixing device. Background Art

[0002] Dentistry is one of the medical disciplines. The main categories of dentistry are oral diseases, teeth, and dental lesions. These three categories can be further divided into oral beauty, dental implants, orthodontics, oral ulcers, oral inflammation, etc. During the treatment process of the dentistry department, dental radiography is required. Dental radiographs refer to X-rays of teeth. Doctors use this type of dental film when they want to observe a single tooth. At this time, taking a small dental film will be clearer than a panoramic film. It is the most widely used examination method in the dentistry department and the most commonly used because it helps with diagnosis and treatment before, during and after dental treatment. Dental films are divided into partial dental films and full-mouth curved surface films. Partial dental films can generally capture three teeth.

[0003] When taking dental films during dental treatment, in order to better observe the status of the dental films, the dental films need to be X-rayed. However, during the dental X-ray process, patients are prone to inadvertently close their mouths, which affects the dental X-ray effect and further affects the overall treatment work. For this reason, we propose a portable oral dental film fixing device. Utility Model Content

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] The utility model provides Figure 1-4A portable oral dental film photography fixing device is shown, comprising an expansion frame 1, a support frame 2 is distributed at both ends of the expansion frame 1, and a positioning ring 3 is sleeved on the top of the middle part of the support frame 2, the expansion frame 1 comprises a slat frame 101, and a silicone strip 102 is connected to one side of the slat frame 101, an articulator 103 is distributed at both ends of the slat frame 101, and a telescopic pile 207 is connected to one side of the articulator 103, and a positioning buckle 104 is connected to the outer wall of the other side of the articulator 103;

[0028] In order to maintain the stability of the support of this device when expanding and fixing the patient's tooth position, such as Figure 1 As shown, the device is composed of a support frame 2 and an articulator 103 at both ends, and the interior of the support frame 2 is composed of a slat frame 101 and a silicone strip 102. The slat frame 101 and the articulator 103 can support the patient's upper and lower jaws during use, and the silicone strip 102 connected to one side of the slat frame 101 can flip up the upper and lower lips during the support process, which is more conducive to the angle of dental film photography.

[0029] like Figure 2-3 As shown, the support frame 2 includes an outer rod 201, and the bottom end of the outer rod 201 is fixedly connected to the support rod 202, the top of the outer rod 201 is provided with a knob 203, and the bottom end of the knob 203 is connected to a shaft rod 204, one end of the shaft rod 204 is connected to a gear rod 205, and rack rods 206 are attached to both sides of the gear rod 205, and one end of the rack rod 206 is connected to a telescopic pile 207;

[0030] In order to improve the stability and adjustability of the overall fixing device when fixing it to the patient's mouth, Figure 2-3 As shown, when the expansion frame 1 is placed in the patient's mouth for support, the user can rotate the knob 203 and the shaft 204, and the gear rod 205 connected to the bottom end of the shaft 204 drives the meshing rack rod 206 and the telescopic pile 207 on both sides to realize the telescopic adjustment process during the support process, so that the expansion angle of the expansion frame 1 can be adaptively adjusted according to the patient and the dental film shooting conditions, so as to keep the support and adjustment process stable, making it easier for the patient to cooperate with X-ray photography, and the overall support frame 2 is small in size, and the telescopic piles 207 at both ends and the articulator 103 are detachable, which is easy to carry and use, so as to cope with various situations.

[0031] like Figure 4 As shown, the positioning collar 3 includes a ring tube 301, and the inner wall of the ring tube 301 is fitted with a positioning rail 302, the inner wall of the positioning rail 302 is fitted with an outer rod 201, and the top of the inner wall of the ring tube 301 is provided with an inner groove 303, and the inner wall of the inner groove 303 is fitted with a knob 203;

[0032] Finally, in order to maintain the stability of the overall support angle after the knob 203 is adjusted, Figure 4As shown, by sliding the ring tube 301 along the top of the outer rod 201, the inner groove 303 at the top of the inner wall of the ring tube 301 is aligned with the outer wall portion around the knob 203, and the knob 203 cannot rotate due to the structural characteristics of the ring tube 301's own positioning slide rail 302, thereby maintaining the stability of the supporting process.

[0033] In summary, when the fixing device is used, the patient is first guided to open his mouth, and the two sets of unexpanded slat frames 101 are placed in the patient's mouth and teeth. The two ends of the teeth are clamped by the positioning buckles 104 of the articulators 103 at both ends. After the initial clamping is completed, the user rotates the knob 203 at the top of the outer rod 201, and the knob 203 drives the shaft rod 204 and the gear rod 205 connected to the bottom to rotate synchronously. Then, the synchronously rotating gear rod 205 drives the meshing rack rods 206 on both sides to extend and retract synchronously, and then cooperates with the telescopic pile 207 connected to one end of the rack rod 206 to form an expansion process with the articulator 103 connected thereto. After the expansion adjustment is completed, the ring tube 301 is pulled up along the top of the outer rod 201, and the knob 203 is clamped and positioned around the ring tube 301 to complete the adjustment support positioning process. Then, the operator cooperates with the X-ray equipment to photograph the patient's tooth position.
