Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral and maxillofacial surgical navigation technology, and in particular to a binocular optical surgical positioning and navigation device. Background Technology
[0002] Binocular optical navigation systems typically use two image sensors to perform three-dimensional positioning of instruments or reference frames with reflective spheres or actively luminous markers as reference objects. They are often used in surgical environments such as complex tooth extractions, alveolar process trimming, bone augmentation surgery, and implant placement in alveolar surgery.
[0003] In the aforementioned surgical environment, image sensors are highly susceptible to contamination from blood mist or droplets. Traditional protective window wiping, due to the limitations of the operating environment, easily leaves behind biological grease or fibers. These contaminants not only alter the refractive index, causing a shift in the interference filtering effect and distortion of the image spectrum, but also produce glare and fogging phenomena due to the diffusion and scattering of light, resulting in blurring of critical details such as microvessels. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a binocular optical surgical positioning and navigation device, which adopts a quick disassembly and replacement method to replace the traditional wiping method, without affecting the overall positioning accuracy, and is better suited for oral surgery that is prone to contamination.
[0005] This utility model provides a binocular optical surgical positioning and navigation device, including a binocular main unit, a quick-connect protrusion, and an infrared-transmitting protective window. The quick-connect protrusion is disposed on the binocular main unit and is positioned opposite to the binocular main unit. The infrared-transmitting protective window rotates when aligned with the quick-connect protrusion, so as to achieve detachable locking between the infrared-transmitting protective window and the quick-connect protrusion.
[0006] In one embodiment, the quick-connect protrusion includes an annular body with a quick-connect groove. The annular body is disposed on the binocular host. Correspondingly, the infrared-transmitting protective window includes a window body and a quick-connect post. The quick-connect post is disposed on the window body.

[0007] In one embodiment, the quick-connect slot includes a slot body with a notch, and one end of the notch is provided with an alignment port. The quick-connect post includes a main body and a limiting slider. The window is connected to the limiting slider through the main body. The limiting slider is inserted into the slot body through the alignment port and moves along the notch so that the slider moves away from the alignment port, thereby realizing that the quick-connect post can be detachably locked in the quick-connect slot.
[0008] In one embodiment, the binocular host includes a first housing, a second housing, a binocular sensor board, a data acquisition and processing board, and an image processing board. The first housing and the second housing are connected to form an assembly cavity. The first housing has a window opposite to the position of the binocular sensor board. The quick-connect protrusion is assembled at the window position of the first housing. The binocular sensor board, the data acquisition and processing board, and the image processing board are assembled in the assembly cavity, and the binocular sensor board is opposite to the window position. The binocular sensor board is electrically connected to the data acquisition and processing board, and the data acquisition and processing board is electrically connected to the image processing board.
[0009] In one embodiment, the second housing includes a housing body and a positioning stake. The positioning stake is assembled inside the housing body. Correspondingly, the first housing is provided with bolt holes, and the binocular sensor board, data acquisition and processing board, and image processing board are provided with through holes. The positioning stake is sequentially inserted into the through holes of the image processing board, data acquisition and processing board, and binocular sensor board. The bolt is inserted into the threaded hole and threadedly connected to the positioning stake to realize the connection between the first housing and the housing body.
[0010] In one embodiment, the positioning pile includes a pile body and a plurality of supporting blocks.

[0018] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0020] The terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.
[0022] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.
[0023] Please see Figure 1 and Figure 2The binocular optical surgical positioning and navigation device provided by this utility model includes a binocular main unit 1, a quick-connect protrusion 201 and an infrared protective window 202. The quick-connect protrusion 201 is disposed on the binocular main unit 1 and is positioned opposite to the binocular main unit 1. The infrared protective window 202 rotates when aligned with the quick-connect protrusion 201, so as to achieve detachable locking between the infrared protective window 202 and the quick-connect protrusion 201.
[0024] It is understandable that a sealing ring can be set between the infrared-transmitting protective window 202 and the binocular host 1. The infrared-transmitting protective window 202 can transmit visible light and can be used in conjunction with the binocular host 1. It can protect the binocular host 1 and prevent it from being contaminated. The infrared-transmitting protective window 202 and the quick-connect protrusion 201 form a quick-connect assembly 2. The infrared-transmitting protective window 202 is easy to disassemble and clean. The binocular host 1 can be used to acquire image data of instruments with reflective balls, active light-emitting markers or reference frames. The instruments can be instruments used for oral cleaning or some instruments used for oral surgery, and they are used as references for three-dimensional positioning, thereby providing positioning information for doctors and improving the accuracy of operation.
[0025] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the quick-connect protrusion 201 includes an annular body 201a, on which a quick-connect groove is provided. The annular body 201a is disposed on the binocular host 1. Correspondingly, the infrared protective window 202 includes a window body 202b and a quick-connect post 202a. The quick-connect post 202a is disposed on the window body 202b. When the window body 202b is aligned with the annular body 201a, the window body 202b is rotated so that the quick-connect post 202a can be detachably locked in the quick-connect groove.
[0026] It is understood that the annular body 201a can be an integral structure with the binocular host 1, and the window 202b can include an outer frame and infrared transmission glass. The infrared transmission glass is embedded in the outer frame and can be in the 850nm and 940nm bands. Anti-slip protrusions can also be provided on the outer surface of the outer frame. The quick-connect post 202a is set on the outer frame. When the window 202b is aligned with the annular body 201a, that is, when the quick-connect post 202a is inserted into the corresponding position of the quick-connect slot, the window 202b drives the quick-connect post 202a to rotate, so that the quick-connect post 202a moves away from the initial position, so that the quick-connect post 202a can be detachably locked in the quick-connect slot.
[0027] Please continue reading. Figure 3In some embodiments, the quick-connect slot includes a slot body 201b with a notch and an alignment port 201c at one end of the notch. The quick-connect post 202a includes a main body and a limiting slider. The window 202b is connected to the limiting slider through the main body. The limiting slider is inserted into the slot body 201b through the alignment port 201c and moves along the notch so that the limiting slider moves away from the alignment port 201c, thereby enabling the quick-connect post 202a to be detachably locked in the quick-connect slot.
[0028] It is understandable that the size of the notch is smaller than that of the groove, and the shape and size of the alignment port 201c are adapted to the limiting slider. The limiting slider is inserted into the groove through the alignment port 201c, and the size of the limiting slider is larger than that of the notch, so that the limiting slider is restricted in the groove. The size of the main body and the notch are adapted to each other, and there is a certain frictional resistance between the limiting slider and the groove. Therefore, without the action of external force, the limiting slider will be relatively stable in the fixed position in the groove. When disassembly is required, it is only necessary to rotate in the opposite direction to return to the position of the alignment port 201c. The quick-connect groove and quick-connect post 202a of this structure are convenient and quick to disassemble and fix.
[0029] Please see Figure 1 In some embodiments, the binocular host 1 includes a first housing 101, a second housing 105, a binocular sensor board 102, a data acquisition and processing board 103, and an image processing board 104. The first housing 101 and the second housing 105 are connected to form an assembly cavity. The first housing 101 is provided with a window that is opposite to the position of the binocular sensor board 102. A quick-connect protrusion 201 is assembled at the window position of the first housing 101. The binocular sensor board 102, the data acquisition and processing board 103, and the image processing board 104 are assembled in the assembly cavity, and the binocular sensor board 102 is opposite to the window position. The binocular sensor board 102 is electrically connected to the data acquisition and processing board 103, and the data acquisition and processing board 103 is electrically connected to the image processing board 104.
[0030] It is understood that the first housing 101 and the second housing 105 are adapted in shape and size. The first housing 101 and the second housing 105 can be in the form of a chamfered rectangle. The size of the window is smaller than the quick-connect bump. The quick-connect bump is arranged around the window. The binocular sensor board is close to the window and is opposite to the window position. The data acquisition and processing board 103 processes the data acquired by the binocular sensor board 102 and transmits the processed data to the image processing board 104. The image processing board 104 processes the acquired data and outputs position information. The data acquisition and processing board 103 and the image processing board 104 can be in the form of UltraScale+ MPSoC FPGA. The data processing logic of the data acquisition and processing board 103 and the image processing board 104 is known in the market.
[0031] Please continue reading. Figure 1In some embodiments, the second housing 105 includes a housing body 105a and a positioning post 105b. The positioning post 105b is assembled inside the housing body 105a. Correspondingly, the first housing 101 is provided with bolt holes, and the binocular sensor board 102, the data acquisition and processing board 103, and the image processing board 104 are respectively provided with through holes. The positioning post 105b is inserted into the through holes of the image processing board 104, the data acquisition and processing board 103, and the binocular sensor board 102 in sequence. The bolt is inserted into the threaded hole and threadedly connected to the positioning post 105b to realize the connection between the first housing 101 and the housing body 105a.
[0032] It is known that the positioning stake 105b can position and fix the binocular sensor board 102, the data acquisition and processing board 103 and the image processing board 104, and also facilitates the fixing between the first housing 101 and the second housing 105.
[0033] Please see Figure 1 In some embodiments, the positioning pile 105b includes a pile body and several top support blocks. The pile body is assembled on the housing body, and the several top support blocks are arranged around the pile body. The pile body passes through the through holes of the image processing board 104, the data acquisition and processing board 103 and the binocular sensor board 102, and the top support blocks support the image processing board 104, the data acquisition and processing board 103 and the binocular sensor board 102.
[0034] It is understood that the top support block can be an integral structure with the pile body, and there is a certain distance between it and the end of the pile body. The image processing board 104, the data acquisition and processing board 103, and the binocular sensor board 102 are connected to the pile body through perforations. The top support block is in close contact with the image processing board 104, so that the image processing board 104, the data acquisition and processing board 103, and the binocular sensor board 102 are in close contact with the first housing 101, thereby improving the stability of the image processing board 104, the data acquisition and processing board 103, and the binocular sensor board 102.
[0035] Please see Figure 2 In some embodiments, the binocular sensor board 102 includes an assembly plate 102c, two image sensors 102b and a heat sink 102a. The two image sensors 102b and the heat sink 102a are assembled on the assembly plate 102c, and the heat sink 102a is attached between the two image sensors 102b. The image sensors 102b are positioned opposite to the window.
[0036] It is understandable that the heat sink 102a can be a metal plate, and the heat sink 102a can also have a cavity reserved inside for the protection of the wires connecting the two image sensors 102b. The image sensor 102b can be connected to the assembly plate 102c by means of adhesive or bolt connection, and the heat sink 102a can effectively dissipate heat from the image sensor 102b.
[0037] As described above, the binocular optical surgical positioning and navigation device provided by this utility model adopts a quick disassembly and replacement method, replacing the traditional wiping method, without affecting the overall positioning accuracy, and is better suited for oral surgery that is prone to contamination.
