Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a wireless, fast-scanning digital impression device for the oral cavity. Background Technology

[0002] The Wireless Intraoral Scanner is an optical 3D scanning device used in dentistry. It replaces the traditional and uncomfortable silicone rubber impression method. By emitting light bands (such as blue LED structured light) and capturing optical images reflected from the tooth surface, it uses algorithms to reconstruct high-precision 3D digital models of soft and hard tissues such as teeth and gums in real time.

[0003] Existing wireless digital impression scanners require strict disinfection and sterilization of the scanning head after contact with the patient's oral environment before use on the next patient. This cumbersome and time-consuming process significantly impacts clinical diagnostic and treatment efficiency. Current methods often involve disassembling the scanning head for disinfection, separating the digital impression scanner into two parts: the main body and the scanning head. These parts are then wiped with chemical disinfectants. However, repeated disassembly and disinfection can damage the delicate optical components on the scanning head's surface, affecting scanning accuracy and device lifespan. Furthermore, the process is cumbersome and cannot be performed with one hand, thus impacting overall effectiveness.

[0004] Therefore, a wireless, fast-scanning digital impression device for the oral cavity was designed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a wireless, rapid digital dental impression scanner. It solves the problems of existing wireless dental scanners, such as the need to disassemble and disinfect the scanning head after use, the cumbersome process, the risk of damage to precision optical components from repeated operation, the impact on scanning accuracy and equipment lifespan, the inconvenience of operation, and the inability to complete the process quickly with one hand.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wireless, fast-scanning digital impression device for oral cavity includes an impression device body, on which a scanning head and control buttons are provided. A sealing sleeve for protecting the scanning head is fitted on one end of the impression device body near the scanning head. Two limiting plates for fixing the sealing sleeve are provided on the symmetrical sides of the impression device body.

[0007] Preferably, the opening end of the sealing sleeve is fixedly provided with two elastic bands, and the two elastic bands are symmetrically distributed.

[0008] Preferably, the housing of the impression device body has two symmetrical insertion slots, which are located on the side near the control button.

[0009] Preferably, the limiting plate is hinged to the inside of the insertion groove by a damping hinge at one end.

[0010] Preferably, a threading groove is provided on the side of the limiting plate away from the hinge end, through which the elastic band can pass.

[0011] Preferably, the diameter of the threading groove is larger than the cross-sectional size of the elastic band, so that it can be threaded quickly.

[0012] Preferably, a protrusion is fixedly provided on the side of the limiting plate opposite to the body of the impression instrument, and a rotating block is rotatably provided on the protrusion.

[0013] Preferably, the limiting plate has two states: a stored state, in which it rotates via a damping hinge and is housed within the insertion slot; and a working state, in which it rotates via a damping hinge to be perpendicular to the side of the impression instrument body.

[0014] Preferably, the rotating block is made of magnetic material, and the impression instrument body is made of magnetic material or has magnetic components in the area near the insertion slot.

[0015] Preferably, when the limiting plate is in working state and the rotating block is rotated to be perpendicular to the protrusion, the rotating block is attracted and fixed to the magnetic part of the impression instrument body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention reduces the risk of cross-infection due to incomplete disinfection by using a disposable sealing sleeve, greatly improving the safety of diagnosis and treatment. It eliminates the traditional cumbersome disassembly, wiping, soaking, or high-temperature and high-pressure disinfection process, and the replacement operation can be completed in seconds, significantly shortening the interval between diagnosis and treatment and improving clinical work efficiency. It avoids repeated contact and corrosion of the precision optical window on the surface of the scanning head by chemical disinfectants, and also avoids mechanical wear and damage caused by repeated disassembly and assembly, effectively extending the service life of the core scanning components and ensuring long-term stable scanning accuracy. The unique damping hinge, wire groove, and magnetic attraction design make the fixing and disassembly process simple, intuitive, and secure, ensuring the stability of the equipment during scanning.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] Please see Figure 1-5A wireless, fast-scanning digital impression device for the oral cavity includes an impression device body 1, on which a scanning head 11 and a control button 12 are provided. A sealing sleeve 2 for protecting the scanning head 11 is fitted on one end of the impression device body 1 near the scanning head 11. Two limiting plates 3 for fixing the sealing sleeve 2 are provided on the symmetrical sides of the impression device body 1.

[0025] Two elastic bands 21 are fixedly provided at the open end of the sealing sleeve 2, and the two elastic bands 21 are symmetrically distributed; The housing of the impression machine body 1 has two symmetrical insertion slots 13. The insertion slots 13 are located on the side near the control button 12. The limiting plate 3 is hinged to the inside of the insertion slot 13 by a damping hinge 31 at one end. A threading groove 32 is provided on the side of the limiting plate 3 away from the hinge end. The elastic band 21 can pass through the threading groove 32. The diameter of the threading groove 32 is larger than the cross-sectional size of the elastic band 21, so that it can be quickly inserted.

[0026] A protrusion 33 is fixedly provided on the side of the limiting plate 3 away from the impression instrument body 1. A rotating block 331 is rotatably provided on the protrusion 33. The limiting plate 3 has two states: one is the storage state, in which it rotates through the damping hinge 31 and is housed in the insertion groove 13; the other is the working state, in which it rotates through the damping hinge 31 to be perpendicular to the side of the impression instrument body 1. The rotating block 331 is made of magnetic material. The impression instrument body 1 is made of magnetic material or has magnetic components in the area near the insertion groove 13. When the limiting plate 3 is in the working state and the rotating block 331 rotates to be perpendicular to the protrusion 33, the rotating block 331 is attracted and fixed to the magnetic part of the impression instrument body 1.

[0027] The quick fixing and disassembly of the device are achieved by the limiting plates 3 symmetrically set on both sides of the main body. When in use, the operator first puts the device in the storage state, and the limiting plates 3 are housed in the insertion slot 13. The limiting plates 3 are rotated to the working state perpendicular to the side of the main body. Then, the elastic bands 21 symmetrically fixed at the opening end of the sealing sleeve 2 are passed through the wire grooves 32 on the corresponding limiting plates 3. Since the size of the wire grooves 32 is larger than the cross-section of the elastic band 21, this insertion operation is extremely convenient. Finally, the magnetic rotating block on the protrusion 33 of the limiting plate is rotated to be perpendicular to the protrusion 33, so that it is attracted and fixed to the magnetic part on the body of the impression instrument 1. Thus, the tension of the elastic band 21 is used to firmly and tightly tighten the sealing sleeve 2 outside the scanning head, ensuring that it will not loosen or fall off during the scanning process. By using the limiting plate 3 for limiting and magnetic locking, the disposable sealing sleeve is reliably fixed to the equipment, realizing a physical isolation barrier. After the work is completed, only the reverse operation is required: release the magnetic attraction and remove the elastic band 21 from the threading groove 32. The used sealing sleeve 2 and the elastic band 21 on it can be quickly discarded as medical waste, and then a new sterile sealing sleeve can be installed for the next patient.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
