Abstract

This invention provides a method for locating acupoints on the knee joint. The method utilizes a 3D scanning device to scan the lower limbs of the human body, establishes a 3D human body model based on the acquired information, and establishes a coordinate system within the established 3D human body model. A standard human body model is compared with the established 3D human body model to obtain a conversion ratio between the models.

This method allows for clear observation of the morphology and structure of the knee joint, as well as the distribution of acupoints on the knee joint, providing more intuitive and comprehensive knee joint information. Simultaneously, the acupoint positioning method is more accurate and objective, reducing the influence of human factors and improving the accuracy of knee joint acupoint positioning.

Description

Technical Field

[0001] This invention relates to the field of acupoint location technology, specifically to a method for locating acupoints on the knee joint. Background Technology

[0002] Acupoints are closely related to the theories of Traditional Chinese Medicine (TCM). TCM believes that stimulating acupoints can regulate the flow of Qi and blood within the body, playing a role in the treatment of diseases and the maintenance of health. Therapies such as massage, acupuncture, cupping, and moxibustion often utilize acupoints for treatment. The knee area has many acupoints for health maintenance. In TCM, these acupoints are typically stimulated through moxibustion or massage to relieve knee pain, fatigue, and other discomfort, and to promote blood circulation in the knee area.

[0003] Ensuring the accuracy of acupoint location is crucial for acupoint stimulation. Currently, no imaging technology can clearly display the true structure of acupoints and meridians in the human body, making their structure difficult to observe. Furthermore, some landmark structures in classic acupoint location methods are too small to be distinguished in images.

[0004] Therefore, we propose a method for locating acupoints on the knee joint. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a method for locating acupoints on the knee joint.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A method for locating acupoints on the knee joint, comprising the following steps:

[0008] The lower limbs of the human body are scanned using a 3D scanning device. A 3D human body model is built based on the information obtained, and a coordinate system is established in the 3D human body model.

[0009] The conversion ratio between the standard human body model and the established 3D human body model is obtained by comparing them.

[0010] Determine the length represented by 1 inch of the standard human body model. Based on the conversion ratio between the standard human body model and the established 3D human body model, determine the length represented by 1 inch of the established 3D human body model.

[0011] A three-dimensional positioning method is constructed to locate acupoints in a coordinate system.

[0012] Furthermore, a coordinate system is established in the constructed three-dimensional human body model, with the Weizhong acupoint selected as the origin of the coordinate system. The left-right direction of the three-dimensional human body model is the x-axis direction, with the x-coordinate value increasing from right to left. The front-back direction of the three-dimensional human body model is the y-axis direction, with the y-coordinate value increasing from back to front. The up-down direction of the three-dimensional human body model is the z-axis direction, with the z-coordinate value increasing from bottom to top.

[0013] Furthermore, the conversion ratio between the standard human body model and the established 3D human body model is obtained by comparing them, including:

[0014] The folded dimensions from the transverse crease of the standard human body model to the tip of the lateral malleolus are measured. The folded dimensions from the transverse crease of the standard human body model to the tip of the lateral malleolus are also measured in the three-dimensional human body model. The folded dimensions of the standard human body model and the three-dimensional human body model are compared to obtain the conversion ratio between the standard human body model and the three-dimensional human body model.

[0015] Furthermore, the length represented by 1 inch of a standard human body model is determined, including:

[0016] Measure the folded dimension from the transverse crease of the standard human model to the tip of the lateral malleolus, measure the size of the lower leg in the standard human model, and compare the size of the lower leg with the folded dimension to obtain the length represented by 1 straight inch of the standard human model.

[0017] Furthermore, the three-dimensional positioning method includes the body surface landmark method and the distance calculation from the acupoint to the origin of the coordinate system.

[0018] Furthermore, the surface landmark method includes the following process:

[0019] Select specific surface landmarks at the knee joint, and move a specific distance in a specific direction from the surface landmarks to determine the location of the acupoints.

[0020] Furthermore, the expression for calculating the distance from the acupoint to the origin of the three-dimensional coordinate system is as follows:

[0021]

[0022] Where d is the distance from the acupoint to the origin of the coordinate system, (X0,Y0,Z0) is the spatial coordinate of the origin of the coordinate system in the coordinate system, and (X1,Y1,Z1) is the spatial coordinate of the acupoint in the coordinate system.

[0023] Compared with the prior art, the present invention has the following technical effects:

[0024] This invention provides a method for locating acupoints on the knee joint. This method uses a three-dimensional human body model to accurately describe the acupoints on the knee joint. A coordinate system is established within the three-dimensional human body model, and a three-dimensional positioning method is constructed to accurately locate the acupoints within the coordinate system. Finally, the acupoints are displayed in a three-dimensional medical image of the human body. Displaying acupoints on the knee joint through a three-dimensional medical image allows for clear observation of the knee joint's morphology, structure, and the distribution of acupoints, providing more intuitive and comprehensive information about the knee joint and aiding in the understanding and analysis of its structure and function. Furthermore, this method provides more accurate and objective acupoint location, reduces the influence of human factors, can accommodate different knee joint shapes and structures, and improves the accuracy of acupoint location.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] Please see Figure 1 This embodiment provides a method for locating acupoints on the knee joint, including the following steps:

[0034] Step 1: Use a 3D scanning device to scan the lower limbs of the human body, and use 3D software to create a 3D human body model based on the scanned information. Establish a coordinate system in the 3D human body model.

[0035] Step 2: Take a standard human body model and measure the folding distance from the popliteal crease (knee bent at the level of the Dubi acupoint) to the tip of the lateral malleolus. Take the established three-dimensional human body model and measure the folding distance from the popliteal crease (knee bent at the level of the Dubi acupoint) to the tip of the lateral malleolus. Compare the folding distance of the standard human body model with the folding distance of the established three-dimensional human body model to obtain the conversion ratio between the standard human body model and the established three-dimensional human body model.

[0036] Step 3: In 3D software, measure the size of the lower leg in the standard human body model by drawing polylines. At the same time, combine the measured distance from the transverse crease (knee bent at the Dubi acupoint) to the tip of the lateral malleolus in Step 2. Compare the size of the lower leg with the measured distance to obtain the length represented by 1 straight inch of the standard human body model. Based on the conversion ratio between the standard human body model and the established 3D human body model obtained in Step 2, calculate the length represented by 1 straight inch of the established 3D human body model. Then, establish a measurement line segment based on the length represented by 1 straight inch of the established 3D human body model.

[0037] Step 4: Construct a three-dimensional positioning method to locate acupoints in a coordinate system, perform standardized descriptions of acupoints in the coordinate system, and finally display acupoints in a three-dimensional medical image of the human body.

[0038] For details, please refer to Figures 2 to 3In step one, a coordinate system is established within the created 3D human body model. Based on the information from the 3D scanning equipment, the acupoint Weizhong (BL40) is located at the midpoint of the popliteal crease, between the tendons of the biceps femoris and semitendinosus muscles. Weizhong is selected as the origin of the coordinate system. Since the human body has front, back, left, right, up, and down directions, the coordinate axes of the coordinate system are determined based on these directions within the model. The left-right direction of the 3D human body model is selected as the x-axis, with x-coordinate values ​​increasing from right to left. The front-back direction is selected as the y-axis, with y-coordinate values ​​increasing from back to front. The up-down direction is selected as the z-axis, with z-coordinate values ​​increasing from bottom to top.

[0039] Specifically, in step four, the three-dimensional positioning method includes the surface landmark method and the distance calculation from the acupoint to the origin of the coordinate system. The surface landmark method is a commonly used method in traditional Chinese medicine acupuncture and massage practice. It determines the location of acupoints by identifying and utilizing specific landmarks on the human body surface. Classical TCM acupuncture acupoint positioning methods determine the location of acupoints through a two-dimensional description of the human body surface. Typically, this description starts from a specific surface landmark and moves a certain distance in a specific direction to reach the target acupoint.

[0040] Acupoints on the limbs are generally located using the "direct measurement" method. Acupoints located on the lateral knee joint are located using surface landmarks. For example, the Jianxi acupoint is located "on the midline of the anterior thigh, directly above the patella, in the rectus femoris muscle, 4 cun above the midline of the patella; there are 2 acupoints on each side." Using the surface landmark method, specific surface landmarks at the knee joint are selected, and the distances to each part are measured to determine the location of the acupoints. The Heding, Xiyan, Yinlingquan, and Yanglingquan acupoints are then located on a coordinate system. Specifically, the Heding acupoint is located above the knee, in the depression at the midpoint of the patella's base; the Xiyan acupoint is located on the extensor surface of the knee joint, in the depressions on either side of the patellar ligament; the Yinlingquan acupoint is located in the depression connecting the lower edge of the medial malleolus to the medial side of the tibia; and the Yanglingquan acupoint is located on the lateral side of the lower leg, in the depression anterior and inferior to the head of the fibula.

[0041] The advantage of surface landmarks is that when determining the location of acupoints, there is no need to consider other uneven shapes on the human body surface that are irrelevant to the location. The human body landmarks used for acupoint location are present in every individual, and their shapes are clear and distinct. Although these landmarks may vary to some extent between different individuals, their relative positions are stable, and these morphological or bony landmarks on the body surface follow certain rules.

[0042] Please see Figure 4 To calculate the distance from an acupoint to the origin of the coordinate system, taking Yanglingquan acupoint as an example, Yanglingquan acupoint is located on the lateral side of the lower leg, in the depression below and in front of the head of the fibula. Based on the established coordinate system, connect Yanglingquan acupoint to the origin of the coordinate system, and project this line onto the x-axis, y-axis, and z-axis respectively, obtaining points perpendicular to the x-axis, y-axis, and z-axis, denoted as X1, Y1, and Z1. Then, determine the distances along the x-axis, y-axis, and z-axis in 3D software.

[0043] The distance from Yanglingquan to the origin of the coordinate system can be obtained by calculating the expression:

[0044]

[0045] The distances to other acupoints can also be determined using this method.

[0046] Where d is the distance from Yanglingquan to the origin of the coordinate system, (X0,Y0,Z0) are the spatial coordinates of the origin of the coordinate system in the coordinate system, and (X1,Y1,Z1) are the spatial coordinates of Yanglingquan in the coordinate system.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
