Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to an intraoperative plastic surgery monitoring method and related equipment. Background Technology

[0002] Plastic surgery is a highly precise and high-risk clinical treatment technique; surgical failure can cause significant suffering for patients. With increased economic strength and more progressive and open social attitudes, an increasing number of patients with facial deformities due to congenital or acquired reasons are seeking medical treatment and correction. Currently, a large number of patients undergoing rhinoplasty are seeking cosmetic enhancement, including many who have experienced failed procedures and are seeking corrective surgery. A lack of preoperative planning and reliable prediction of contour changes can lead to unsatisfactory surgical results, increasing patient suffering and the risk of secondary surgery. Therefore, thorough preoperative planning and reliable prediction of contour changes are crucial for successful preoperative preparation, intraoperative procedures, and postoperative evaluation.

[0003] 3D scanning is a technology that uses optical stereoscopic vision to non-contactly capture light projected onto the surface of a target, constructing a three-dimensional digital information representation of the target's surface contour. Currently, the two most commonly used methods for 3D facial scanning are binocular scanning and structured light scanning. After scanning, a 3D reconstruction method is used, with computer algorithms calculating the 3D data to obtain a 1:1 replica of the scanned face. This 3D model typically consists of a triangular mesh and a color texture map. In professional 3D visualization software, this 3D model can be realistically viewed, and 3D data can be measured and analyzed, as well as used to simulate plastic surgery and repair procedures.

[0004] Currently, 3D scanning technology is mainly used in the pre-operative simulation stage of plastic surgery in reconstructive surgery. Although doctors can use 3D technology to provide some reference, the simulated design plan is only for reference. The implementation of a surgical plan is a highly specialized and complex system engineering project, in which many details and factors will affect the final result. Therefore, the current planning before plastic surgery still has significant shortcomings. Summary of the Invention

[0047] like Figure 1 As shown, this embodiment provides an intraoperative plastic surgery monitoring method. To simulate a real-world scenario, this embodiment focuses on an intraoperative plastic surgery monitoring device that performs the method. The device includes a scanner for performing three-dimensional scanning of a human face. Furthermore, the device performing the method can also be a server or other equipment with data processing capabilities. The intraoperative plastic surgery monitoring method includes the following steps:

[0048] S10. Obtain initial face shape information and expected face shape information.

[0049] Specifically, before the surgery begins, the intraoperative plastic surgery monitoring equipment first obtains initial facial shape information and expected facial shape information from the database. The initial facial shape information is the facial shape information of the surgical subject collected previously, and the expected facial shape information is the expected facial shape information after the surgery.

[0050] During the initial consultation with the surgical patient, before determining the surgical plan, the doctor needs to use a scanner with intraoperative plastic surgery monitoring equipment to complete a three-dimensional facial scan to obtain initial facial information and create a corresponding data file to match the surgical patient with the initial facial information.

[0051] During the initial facial structure scan, the patient must wear a headband to expose their hairline and remove any facial accessories to ensure an unobstructed view. They should then sit comfortably 800mm in front of the scanning device. The intraoperative plastic surgery monitoring equipment completes a 3D scan within two seconds and 3D reconstruction within ten seconds, displaying the patient's digital model on the visualization software on the screen, thus obtaining the initial facial structure information.

[0052] Based on initial facial structure information, the doctor and the surgical patient communicate to visually adjust the three-dimensional shape of the initial facial structure. When a modification command corresponding to the initial facial structure information is detected, the initial facial structure information is modified to obtain the desired facial structure. Intraoperative plastic surgery monitoring equipment analyzes the differences between the initial and desired facial structure information, providing data reference for the doctor's surgical plan.

[0053] Taking rhinoplasty as an example, the data analysis of key points of the nose is as follows: Figure 1 As shown. These are the nasal root point, upper nasal bridge point, lower nasal bridge point, highest nasal point, nasal tip point, columellar point, and nasal base point, respectively. After analyzing and recording the matching and alignment of the two facial models, in... Figure 2 The deviation distances at 7 key points are used as a reference for doctors in subsequent surgical procedures.

[0054] S20. When the start command is detected, a facial scan is performed to obtain preoperative facial information.

[0055] Specifically, when surgery is required, the user (usually a doctor or medical assistant) inputs a start command into the intraoperative plastic surgery monitoring device via an external device. Upon receiving the start command, the intraoperative plastic surgery monitoring device rescans the surgical subject to obtain preoperative facial information. Compared to the initial facial information obtained from the first scan, the subject's facial shape may change, such as becoming thinner or heavier; therefore, obtaining preoperative facial information can more accurately assist in the surgical procedure.

[0056] S30. Calculate the initial deviation corresponding to the preoperative facial shape information based on the initial facial shape information.

[0057] Specifically, based on the initial face shape information, the difference between the first face shape and the initial face shape information is calculated to obtain the initial deviation.

[0058] The initial facial structure information and the preoperative facial structure information are fitted together to obtain fitted information. Based on the fitted information, the initial deviation is calculated. The initial deviation includes nasal bridge deviation, which includes deviations at the nasal root point, upper nasal dorsum point, lower nasal dorsum point, highest nasal point, nasal tip point, columellar point, and nasal base point.

[0059] For example, such as Figure 2 As shown, firstly, based on the initial facial structure information and the preoperative facial structure information, the coordinates of feature points are calculated for both, such as the nasal root point, upper nasal bridge point, lower nasal bridge point, highest nasal point, nasal tip point, columellar point, and nasal base point. Based on these feature point coordinates, the preoperative and initial facial structure information are fitted together. Then, the deviations of the nasal bridge from the two are subtracted sequentially to obtain the deviation value for each key point. The average of all key point deviation values ​​is then taken to obtain the initial deviation.

[0060] S40. When the initial deviation is less than or equal to the preset initial deviation threshold, facial scanning is performed intermittently based on the preset scanning instructions to obtain several intraoperative facial information.

[0061] Specifically, an initial deviation threshold is preset. If the initial deviation is less than or equal to the preset initial deviation, it means that the change in the surgical object is not significant, and therefore the surgery can be performed.

[0062] At this point, the user will determine whether to begin surgery based on the comparison between the initial deviation and the initial deviation threshold. The comparison result can be displayed directly through pop-ups, indicator lights, etc.

[0063] A scanning command is pre-programmed into the intraoperative surgical monitoring device. This command instructs the 3D scanning machine to perform facial scanning on the surgical subject according to predetermined rules. For example, the time interval between the previous and subsequent scans can be pre-set, and facial scanning can only be performed when a scan command issued by the user is detected. By setting the scanning command, the 3D scanning machine performs intermittent scans on the surgical subject, obtaining facial information with each scan, thus obtaining several intraoperative facial information sets.

[0064] On the other hand, when the initial deviation exceeds the initial deviation threshold, it indicates a significant difference between the current state of the surgical subject and the state seen in the previous scan. In this case, the doctor will communicate with the surgical subject to determine whether modifications are needed based on the expected facial shape information. If modifications are required, the user sends an update command to the intraoperative plastic surgery monitoring device via an external device. When an update command is detected, the expected facial shape information is updated according to the update command.

[0065] S50. For each of the intraoperative facial shape information, calculate the adjustment deviation based on the expected facial shape information.

[0066] Specifically, each piece of intraoperative facial shape information is an intermediate product of the surgical process. As the surgery progresses, the intraoperative facial shape information becomes increasingly closer to the expected facial shape information. Therefore, such as Figure 3 As shown, for each intraoperative facial feature, it is necessary to calculate the adjustment deviation between it and the expected facial feature.

[0067] To calculate the adjustment deviation, the intraoperative facial structure information and the expected facial structure information are first registered, that is, aligned to the same coordinate system. Then, the difference between the intraoperative and expected facial structure information is calculated using various 3D morphological comparison algorithms, such as least squares and ICP algorithms. Finally, based on the calculation results, the adjustment deviation is obtained, which is the information in the intraoperative facial structure information that needs to be adjusted.

[0068] S60. When the adjustment deviation is less than or equal to the preset intraoperative deviation threshold, a preset prompt window is displayed.

[0069] Specifically, a pre-set intraoperative deviation threshold is used to evaluate the difference between the intraoperative facial shape information and the expected facial shape information. When the adjusted deviation is less than or equal to the pre-set intraoperative deviation threshold, it indicates that the current intraoperative facial shape information is very close to the expected facial shape information. Therefore, a pre-set prompt window is displayed to inform the user that the current result is very close to the expectation. At this point, the user can decide whether to continue the surgery based on the actual situation.

[0070] Furthermore, an evaluation rule for assessing surgical outcomes is pre-defined. This rule includes at least a method for calculating postoperative deviations. Based on this rule, the postoperative deviations corresponding to the adjusted deviations can be calculated, and finally, a postoperative evaluation is generated based on these deviations. One method for calculating postoperative deviations is similar to the methods for calculating initial and adjusted deviations described earlier. For example, the difference values ​​of seven key points on the nose are recorded, and their mean and variance are obtained using statistical methods. The smaller the value, the better the evaluation of the surgical completion, and the smaller the postoperative deviation. Another method for calculating postoperative deviations combines the adjusted deviations corresponding to each intraoperative facial shape information. Based on all adjusted deviations, the postoperative deviation is calculated. For example, the smaller the number of adjusted deviations, the faster and more precise the surgeon was in achieving the desired facial shape, thus resulting in a smaller postoperative deviation.

[0071] This approach utilizes intraoperative facial monitoring equipment to acquire facial information of the surgical subject, enabling more precise surgery. Before surgery, doctors can visually adjust the initial facial information to obtain the desired facial shape, thus better understanding the patient's needs. During the surgery, the difference between the intraoperative facial information and the desired facial shape can be used to assess the progress of the surgery. Furthermore, this approach sets an initial deviation threshold to quantitatively evaluate changes in the surgical subject.

[0072] Based on the above-described intraoperative plastic surgery monitoring method, the present invention also provides an intraoperative plastic surgery monitoring device, such as... Figure 4 As shown, the device includes: a movable base, an operation panel fixedly connected to the movable base, and a scanning module rotatably connected to the movable base.

[0073] The movable base includes a chassis 110, casters 120 disposed at the bottom of the chassis 110, and a support body 130 disposed above the chassis 110. The movable base also includes a handle 140 fixedly connected to the support body 130, which facilitates the user to push the orthopedic monitoring device and allows for flexible movement.

[0074] Because the scanning direction and angle need to be constantly adjusted during surgery, in this embodiment, the scanning module includes a scanner 310, a first support 320 hinged to the scanner 310, a second support 330 hinged to the first support 320, and a rotating rod with its first end fixedly connected to the movable base and its second end movably connected to the second support 330. Through hinges and other movable connections, the scanner 310 can freely adjust its direction to achieve scanning in different directions.

[0075] The movable connection can be achieved using methods such as locking. In this embodiment, for example... Figure 5 As shown, the first end of the connecting rod 340 is fixedly connected to the support body 130, and the second end is provided with a first turntable 341. The first end of the second bracket 330 is provided with a second turntable 332. The first turntable 341 and the second turntable 332 are sleeved together so that the first turntable 341 and the second turntable 332 can rotate relative to each other, thereby allowing the scanner 310 to rotate relative to the movable base and adjust the scanning position. The first end of the second bracket 330 is also provided with a locking member 331. When the locking member 331 is rotated, the distance between the side walls of the first turntable 341 and the second turntable 332 increases or decreases, thereby restricting the left and right swinging movement. When rotation is not required, rotating the locking member 331 reduces the distance between the side walls of the first turntable 341 and the second turntable 332 until they abut, thereby fixing the scanner 310. When rotation is required, rotating the locking member 331 increases the distance between the side walls of the first turntable 341 and the second turntable 332, thereby rotating the scanner 310.

[0076] To achieve the hinge connection between the first support 320 and the second support 330, the second end of the second support 330 is provided with a third turntable 333, and the first end of the first support 320 is provided with a first movable disc 321 and a fourth turntable 323 that is fitted onto the first movable disc 321. The third turntable 333 is fitted onto the first movable disc 321, thereby enabling the third turntable 333 and the fourth turntable 323 to rotate around the first movable disc 321. The movable disc is a disc with protrusions, grooves, and other limiting structures on its side, which achieves the fitting through limiting cooperation, thereby enabling the rotation of the third turntable 333 and the fourth turntable 323. Figure 6 and Figure 7As shown, when the first support 320 rotates, the third turntable 333 and the fourth turntable 323 are positioned opposite each other and are respectively connected to both sides of the first movable disk 321 to achieve relative rotation. When the third turntable 333 and the fourth turntable 323 rotate relative to each other, the included angle between the first support 320 and the second support 330 changes, thereby driving the movement of the scanner 310.

[0077] To achieve the hinge connection between the first support 320 and the scanner 310, the second end of the first support 320 is provided with a second movable disk 322 and a fifth turntable 324 that is sleeved with the second movable disk 322, while a sixth turntable 311 is provided on one side of the scanner 310, and the sixth turntable 311 is sleeved with the second movable disk 322. Figure 8 and Figure 9 As shown, the sixth turntable 311 and the fifth turntable 324 are spaced apart from the second movable disc 322 and are respectively fitted onto both sides of the second movable disc 322 to achieve relative rotation. Since the movement of the second bracket 330 and the connecting rod 340 requires the locking piece 331 to fix them, once a relatively coarse direction is fixed, it is difficult to adjust the scanner 310 in the left-right direction. Therefore, the first movable disc 321 and the second movable disc 322 are perpendicular to each other. If the first movable disc 321 assists the scanner 310 in vertical movement, then the second movable disc 322 assists the scanner 310 in horizontal movement; conversely, if the first movable disc 321 assists the scanner 310 in horizontal movement, then the second movable disc 322 assists the scanner 310 in vertical movement. Based on this, the above-mentioned intraoperative plastic surgery monitoring device can achieve convenient and rapid adjustment of the scanner 310, improving its efficiency.

[0078] like Figure 10 As shown, the operation module 200 includes at least one processor 20, a display screen 21, and a memory 22. It may also include a communications interface 23 and a bus 24. The processor 20, display screen 21, memory 22, and communications interface 23 can communicate with each other via the bus 24. The display screen 21 is configured to display a preset user guide interface in the initial setup mode. The communications interface 23 can transmit information. The processor 20 can invoke logical commands stored in the memory 22 to execute the methods described in the above embodiments.

[0079] Furthermore, the logical commands in the aforementioned memory 22 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.

[0080] The memory 22, as a computer-readable storage medium, can be configured to store software programs, computer-executable programs, such as program commands or modules corresponding to the methods in the embodiments of this disclosure. The processor 20 executes functional applications and data processing by running the software programs, commands, or modules stored in the memory 22, thereby implementing the methods in the above embodiments.

[0081] The memory 22 may include a program storage area and a data storage area. The program storage area may store the operating system and application programs required for at least one function; the data storage area may store data created based on the use of the terminal device. Furthermore, the memory 22 may include high-speed random access memory (RAM) and non-volatile memory. Examples include various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks; it may also be a transient computer-readable storage medium.

[0082] Furthermore, the specific process of loading and executing multiple command processors in the aforementioned computer-readable storage medium and terminal device has been described in detail in the above method, and will not be repeated here.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
