Technical Field

[0001] The utility model relates to the field of positioning and registration devices for oral navigation, and particularly to a positioning and registration device for oral navigation. Background Art

[0002] A positioning and registration device for oral navigation is a medical device that combines digital technology and navigation technology, and is used to assist doctors in accurately positioning the position, depth, and angle of implants during oral implant surgery, playing a crucial role in oral implant surgery.

[0003] During the operation of this device, the three-dimensional positions of the patient's oral cavity and the instrument itself are obtained by an optical sensor receiving an infrared light emitting device and a receiving device, and the image information of the internal structure of the human body is obtained by combining imaging technologies such as a navigation camera. The three-dimensional image reconstruction software built into the implant handpiece can accurately reconstruct and measure the patient's oral structure, helping dentists formulate more refined surgical plans. However, the current implant handpiece is not equipped with any fixture to enable the relative position of the lesion to be displayed in real time on the camera navigation end, thus bringing great inconvenience to the operation. Therefore, a positioning and registration device for oral navigation is proposed. Summary of the Utility Model

[0004] In view of the deficiencies in the prior art, the utility model provides a positioning and registration device for oral navigation. By providing a matching jacket at the lower part outside the device body for clamping, and at the same time attaching an outer label to the outside of the jacket, the outer label is clear and easy to identify, and is used as a marking point or QR code to match with the navigation camera, so that the navigation camera can quickly and accurately identify it. When the external infrared light passes through the jacket, the image information of the jacket and the lesion can be captured in real time, thus providing great convenience in implant surgery.

[0005] In order to solve the above technical problems, the utility model solves the problem that the implant handpiece in the positioning and registration device for oral navigation does not have a fixture through the following technical solutions.

[0033] Please refer to Figure 1 - Figure 6 , a positioning and registration device for oral navigation, comprising a nose piece 101 and a base 102 provided on a device body 1. A jacket 2 is provided outside the device body 1, and an outer label 201 is attached to the outer surface of the jacket 2 for identification.

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , for the positioning and registration device for oral navigation of the present application, during the operation, the three-dimensional positions of the patient's oral cavity and the instrument itself are obtained by an optical sensor receiving an infrared light emitting device and a receiving device, and the image information of the internal structure of the human body is obtained by combining imaging technologies such as a navigation camera. Then, the device body 1, the nose piece 101 and the base 102 are combined. The device body 1 is the body part of a dental implant handpiece. Holding the base 102 can make the base 102 reach the position of the lesion. The navigation camera performs real-time tracking and positioning in the oral navigation system. By providing a matching jacket 2 at the lower part outside the device body 1 for clamping, and at the same time attaching the outer label 201 to the outside of the jacket 2, the outer label 201 is clear and easy to identify, and is used as a marking point or a two-dimensional code to match with the navigation camera, so that the navigation camera can quickly and accurately identify. When the external infrared light passes through the jacket 2, the image information of the jacket 2 and the lesion can be captured in real time, thus providing great convenience in the dental implant surgery.

[0035] It should also be noted that the jacket 2 has an opening with a certain width to facilitate adapting to the fixing requirements of different device bodies 1. The jacket 2 is made of a material with good infrared light transmittance and certain elasticity to ensure that the jacket 2 does not obstruct the signal emitted by the infrared light locator, so that the infrared light can smoothly pass through the jacket 2 and reach the lesion area to capture images.

[0036] In the present application, a positioning hole 103 and a positioning shaft rod 104 are also provided. The positioning holes 103 are uniformly opened at the outer circumference of the base 102, and the positioning shaft rods 104 are installed at both ends of the bottom of the opening of the jacket 2. After the base 102 is sleeved into the thinner end of the device body 1 and moved from top to bottom to bring the positioning shaft rods 104 into the positioning holes 103, the jacket 2 sleeved on the device body 1 can be positioned.

[0037] In this application, a stabilizing hoop 6 is also provided. A section of thread matching the stabilizing hoop 6 is provided at the outer ring of the bottom of the machine base 102. The stabilizing hoop 6 can be sleeved on the thread by rotating from bottom to top. Its upper end is higher than this thread section and extends to the outside of the machine base 102 and the positioning shaft rod 104. When it is in close fit with the outer wall, it also restricts the position of the positioning shaft rod 104 after being inserted.

[0038] In this application, an outer extension ring 7 and a hand-holding ring opening 701 are also provided. The outer extension ring 7 is fixedly installed at the bottom of the stabilizing hoop 6 and can be located outside the device, facilitating the medical staff to hold it. A plurality of hand-holding ring openings 701 are evenly arranged on its outer ring, which better meets the human hand-holding requirements and can adjust the hand-holding position according to the use direction.

[0039] In this application, a guide plate 3 and a through hole 301 are also provided. The guide plate 3 has a certain slope, so that the through hole 301 can be on the same horizontal line as the machine head 101. When the machine base 102 is aligned with the lesion, the infrared light can pass through the jacket 2 and then penetrate into the interior of the through hole 301 to extend to the lesion aligned by the machine head 101, so as to further locate the lesion.

[0040] In this application, a support rod 4 is also provided. The support rod 4 is connected to the bottom of the guide plate 3 and is elastic, so that it can be bent relatively at the edge of the jacket 2 and then aligned with the machine base 102 after adjustment.

[0041] In this application, an annular inner groove 5 and a rotating member 401 are also provided. The rotating member 401 is installed at the bottom of the support rod 4 and can rotate relatively inside the annular inner groove 5. The annular inner groove 5 is opened at the inner ring of the upper opening of the jacket 2. When moving the guide plate 3 along the outer ring of the extended jacket 2, it can relatively drive the rotating member 401 to rotate inside the annular inner groove 5 to adjust the position of the guide plate 3 on the jacket 2. When the machine head 101 rotates, the position of the guide plate 3 can be changed according to its rotation position, improving the flexibility of the structure.
