DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0028] Example:

[0029] See also Figure 1-6 A portable scanning rod auxiliary device for intraoral scanning of implants comprises: a cheek puller 1, a main scanning slide rail 2 and a scanning assembly 3, wherein the cheek puller 1 comprises a pair of semi-ring blocks, which are connected by a connecting rod, and the semi-ring blocks are used to contact the cheeks of the patient respectively; the main scanning slide rail 2 is connected to the cheek puller 1, and the main scanning slide rail 2 comprises an outer ring body 21 and an inner ring body 22, the outer ring body 21 is arranged on the outside of the inner ring body 22, and the scanning assembly 3 is slidably arranged between the outer ring body 21 and the inner ring body 22; the scanning assembly 3 comprises a handle 4 and a scanner 5, and the scanning assembly 3 is used to realize scanning of the patient's oral cavity.

[0030] Among them, by designing the arc structure of the outer ring body 21, the inner ring body 22 and the reciprocating slide rail 23, it is ensured that the device can fit the shape of the patient's mouth, thereby improving the stability and scanning accuracy of the device. The device uses lightweight non-magnetic materials and performs anti-reflection treatment, which effectively reduces the influence of signal interference and light reflection during scanning, while improving the durability and applicability of the device. The airbag 41 surrounded by the outside of the handle 4 and its linkage design with the connecting pipe 42, the sealing sliding rod 44 and the steering lever 53 can realize flexible adjustment of the angle of the scanner 5. With the rebound function of the elastic connecting sleeve 54, the scanner 5 can maintain flexibility and high stability during the adjustment process. The design of the slide rail system enables the scanning path to be seamlessly switched from horizontal to vertical, ensuring comprehensive coverage of various areas in the oral cavity, which not only improves the operational convenience and accuracy of the scanning process, but also realizes the portability of the equipment through modular design, meeting the requirements of efficiency and precision in clinical applications.

[0031] The outer ring body 21 and the inner ring body 22 are respectively curved arc structures, and both are arc shapes that fit the shape of the patient's mouth when viewed from the front and top. The outer ring body 21 and the inner ring body 22 are fixed by a connecting rod to form an integral structure.

[0032] A reciprocating slide rail 23 is disposed in the inner ring body 22 . The reciprocating slide rail 23 is composed of a plurality of continuous inverted curved V-shaped slide rails, and the reciprocating slide rail 23 is connected to the outer ring body 21 and the inner ring body 22 .

[0033] The longitudinal axes of the multiple V-shaped slide rails match the longitudinal axes of the outer ring body 21 and the inner ring body 22 .

[0034] The outer ring body 21 and the inner ring body 22 are respectively designed as curved arc structures, and their shapes can fit the anatomical contours of the patient's oral cavity from both the front and top view angles. This design not only improves the stability of the device in the patient's oral cavity, but also reduces the patient's discomfort. At the same time, the outer ring body 21 and the inner ring body 22 are fixed by connecting rods to form an integrated overall structure. This overall design enhances the rigidity of the device, ensures the precise positioning and stable operation of the slide rail during scanning, and avoids scanning deviations caused by looseness or deformation.

[0035] A reciprocating rail 23 is arranged inside the inner ring body 22, and the reciprocating rail 23 is composed of a plurality of continuous inverted curved V-shaped rails. The design of each V-shaped rail enables the scanning component to reciprocate up and down along a fixed path during the scanning process, ensuring that the scanner can fully cover different areas in the patient's oral cavity, especially some complex recesses or edge areas. At the same time, the reciprocating rail 23 is connected to the outer ring body 21 and the inner ring body 22. This connection enables the scanning component to smoothly transition to the reciprocating rail 23 on the inner ring body 22 after completing the horizontal circle scanning on the outer ring body 21, realizing seamless switching of the scanning path from horizontal to vertical.

[0036] The longitudinal axes of the multiple V-shaped slide rails match the longitudinal axes of the outer ring body 21 and the inner ring body 22, ensuring that the bending direction of the slide rails is consistent with the geometric shape of the patient's oral cavity, further improving the movement accuracy and fit of the scanning component. It can not only reduce the jitter and positioning errors that may occur during the scanning process, but also improve the overall quality and accuracy of the scanning data, thereby meeting the high-precision requirements of oral models for precision medical operations such as dental implants.

[0037] At the same time, the materials of the outer ring body 21, the inner ring body 22 and the reciprocating slide rail 23 are all made of lightweight and high-strength non-magnetic materials, such as aluminum alloy or high-performance engineering plastics such as POM polyoxymethylene or PEEK polyetheretherketone, which have excellent mechanical properties and can ensure that the device has sufficient structural strength and stability during use. At the same time, its non-magnetic properties avoid interference with the scanning equipment during use.

[0038] In addition, in order to further reduce possible light reflection or signal interference during the scanning process, the surfaces of the outer ring body 21, the inner ring body 22 and the reciprocating slide rail 23 are all subjected to special anti-reflection treatment, such as spraying a matte black coating or using a low-reflective surface texture treatment. This surface treatment can effectively reduce the scattering or reflection of light during the scanning process, thereby improving the accuracy of the scanned data and the imaging quality.

[0039] It can not only significantly reduce the interference of the device to the scanning signal during the scanning process, but also further improve the durability and service life of the device, providing more reliable and stable support for subsequent multiple scans.

[0040] The handle 4 is surrounded and fixedly connected with a plurality of evenly distributed air bags 41 , and an extrusion groove 45 is provided on the handle 4 . The handle 4 is also provided with a plurality of evenly distributed communication pipes 42 matching the air bags 41 .

[0041] An elastic limiting strip 43 is fixedly connected to the inner wall of the communicating pipe 42 , and a sealing sliding rod 44 is slidably connected in the communicating pipe 42 . The elastic limiting strip 43 and the sealing sliding rod 44 are fixedly connected.

[0042] A plurality of steering levers 53 evenly distributed and matching with the airbag 41 are arranged in the extrusion groove 45 , and the bottom end of the sealing sliding rod 44 abuts against the steering lever 53 .

[0043] An elastic connection sleeve 54 is arranged between the handle 4 and the scanner 5 , and two ends of the elastic connection sleeve 54 are respectively connected to the handle 4 and the scanner 5 , and the material of the elastic connection sleeve 54 is set to be a silicone material.

[0044] The scanner 5 is provided with an abutting groove 51 , and a plurality of steering levers 53 penetrate through the elastic connecting sleeve 54 and extend into the abutting groove 51 so as to be rotatably connected to the inner wall of the abutting groove 51 at one end.

[0045] A slider 52 is fixedly connected to one end of the scanner 5 , and the slider 52 is slidably connected to the main scanning slide rail 2 and the reciprocating slide rail 23 .

[0046] Among them, the outside of the handle 4 is surrounded and fixedly connected with a plurality of evenly distributed airbags 41, and these airbags 41 realize the auxiliary function of the handle 4 through reasonable layout. An extrusion groove 45 is provided on the handle 4, which is convenient for medical staff to squeeze the airbag 41 by applying force with their fingers during operation. The handle 4 is also provided with a plurality of evenly distributed connecting pipes 42 that match the airbag 41, and these pipes are used to transfer the gas in the airbag 41 to a specific structural area. An elastic limit strip 43 is fixedly connected to the inner wall of the connecting pipe 42, and the limit strip 43 is used to perform elastic limit control on the sealing sliding rod 44 in the connecting pipe 42. When the airbag 41 is squeezed, the gas pressure pushes the sealing sliding rod 44 to slide downward to overcome the action of the elastic limit strip 43, and realizes the transmission of force through the abutment of the bottom end with the steering lever 53.

[0047] A plurality of steering levers 53 are evenly distributed and matched with the airbag 41 inside the extrusion groove 45. The bottom end of the sealing sliding rod 44 abuts against these steering levers 53, and the gas pressure generated by the airbag 41 is transmitted to the steering lever 53 via the sealing sliding rod 44, causing the steering lever 53 to rotate at a certain angle. The other end of the steering lever 53 penetrates the elastic connecting sleeve 54 and extends into the abutting groove 51 on the scanner 5, forming a rotational connection with the inner wall of the abutting groove 51. Through this structure, the rotation of the steering lever 53 can directly act on the scanner 5, realizing fine adjustment of the scanner angle.

[0048] An elastic connection sleeve 54 is provided between the handle 4 and the scanner 5. The elastic connection sleeve 54 is made of silicone material and has good flexibility and resilience. The two ends of the elastic connection sleeve 54 are fixedly connected to the handle 4 and the scanner 5 respectively, and its function is to provide a certain range of movement for the scanner 5, and at the same time, it can automatically return to the original position after the external force is removed, thereby improving the stability and flexibility of the scanner.

[0049] In addition, one end of the scanner 5 is fixedly connected with a slider 52, which can be slidably connected in the main scanning slide rail 2 and the reciprocating slide rail 23. In the scanning process, the scanner 5 can not only scan around the oral cavity along the horizontal slide rail, but also scan the upper and lower areas through the longitudinal slide rail, ensuring that all areas in the oral cavity can obtain comprehensive and accurate data collection.

[0050] The flexible adjustment of the angle of the scanner 5 is achieved through the airbag 41 and its matching connecting pipe 42, the sealing sliding rod 44, the steering lever 53, etc., and the smoothness of the adjustment and the automatic reset function are ensured by the elastic connecting sleeve 54. This design greatly improves the operation accuracy and convenience of the scanning process, while ensuring the stability of the equipment in long-term use, and improving the quality and reliability of the overall scanning data.

[0051] Working principle:

[0052] The cheeks of the patient are pulled apart by the cheek puller 1 to provide sufficient space for the installation and operation of the main scanning slide 2 and the scanning assembly 3. The main scanning slide 2 is composed of an outer ring body 21 and an inner ring body 22, which are fixed by a connecting rod to form an integral structure. The outer ring body 21 and the inner ring body 22 are respectively designed to be curved arc structures, and fit the geometric shape of the patient's mouth, so that the device can be stably fixed in the patient's mouth. A plurality of continuously inverted curved V-shaped slide rails 23 are arranged in the inner ring body 22, and these slide rails are connected to the outer ring body 21 and the inner ring body 22, so as to ensure that the scanning assembly 3 can perform a horizontal circular scan on the outer ring body 21, and then realize reciprocating motion in the upward and downward directions through the V-shaped slide rail 23, thereby comprehensively covering different areas in the patient's mouth, especially complex depressions or edge areas;

[0053] The scanning assembly 3 includes a handle 4 and a scanner 5. The handle 4 is surrounded and fixedly connected with a plurality of uniformly distributed airbags 41 on the outside. The airbags 41 are connected to the internal sealing sliding rod 44 through a connecting pipe 42. An elastic limiting strip 43 is arranged in the connecting pipe 42. When the medical staff squeezes the airbag 41 on the handle 4, the gas pressure pushes the sealing sliding rod 44 to slide downward, and abuts against the steering lever 53 through its bottom end to achieve force transmission. One end of the steering lever 53 passes through the elastic connecting sleeve 54 and extends into the abutting groove 51 provided on the scanner 5, forming a rotational connection with the inner wall of the abutting groove 51. When the steering lever 53 is subjected to force and rotates at a certain angle, it can directly act on the scanner 5 to achieve flexible fine adjustment of the scanner angle.

[0054] The elastic connection sleeve 54 is made of silicone material, has good flexibility and resilience, and is fixedly connected between the handle 4 and the scanner 5. Its function is to provide a certain range of motion for the scanner 5, and can automatically return to the original position after the external force is removed, ensuring the stability and flexibility of the scanner 5. The scanner 5 is slidably connected with the main scanning slide 2 and the reciprocating slide 23 through a fixedly connected slider 52, so that the scanner 5 can slide smoothly in the horizontal and vertical directions to complete the scanning of the entire oral area. The entire working process realizes the portability and efficiency of the equipment through modular design, while ensuring the accuracy and comprehensiveness of the scanned data.
