Technical Field

The invention belongs to the technical field of mixed reality and discloses an acupuncture training system and method.

Background

Traditional Chinese medicine acupuncture is a combination of acupuncture and moxibustion, wherein acupuncture is performed by inserting a filiform needle into a certain point of a patient's body and applying acupuncture techniques such as twirling and lifting and inserting to treat diseases. The skilled skill of acupuncture and moxibustion can effectively improve the level of treatment, so certain acupuncture and moxibustion training is usually required to improve the level of acupuncture and moxibustion.

In the teaching process of the traditional Chinese medicine acupuncture, the positioning of acupuncture points and the anatomical explanation of the acupuncture points are limited by word description and two-dimensional picture display, which brings difficulty to the understanding of students, but the students can not directly train through a human body model and can not visually observe and know the related information of the acupuncture points, and can not determine whether the acupuncture is in place; in addition, the existing acupuncture training mode is directly carried out on a human body, or cotton soap and the like are used as auxiliary training tools, and the training modes are backward, so that the human body has high training risk and violates medical ethics; the mode of the paper ball cotton ball is far from the biophysical characteristics of a human body, and the practical training effect is poor; in addition, a virtual acupuncture training system based on a PC and an acupuncture point information acquisition unit is also provided, and the traditional PC is adopted for displaying a digital human body, so that the immersion sense is limited, the operation is complicated, and the operation of the PC and the acupuncture operation need to be switched back and forth.

Therefore, in the prior art, acupuncture training is mainly performed by means of characters, pictures, simple solid models or simple PC interaction, the accuracy of acupuncture cannot be intuitively known, the training effect cannot be mastered, the interestingness is low, and the learning efficiency is not high.

Disclosure of Invention

The invention provides an acupuncture training system, which is used for solving the problems that the traditional training modes such as characters, pictures or simple entity models are not visual enough, the timeliness of acupuncture teaching exercise cannot be ensured, and the training effect is poor in the prior art. Specifically, an acupuncture training system includes:

the acupuncture point sensor is used for sensing whether the acupuncture needle is inserted accurately in place;

the virtual model creating component is used for acquiring three-dimensional model data of the entity training model and creating a virtual training model according to the three-dimensional model data of the entity training model; and

a mixed reality auxiliary component for data registration of the virtual training model and the solid training model such that the virtual training model and the solid training model are coincident from the mixed reality auxiliary component perspective; the mixed reality auxiliary assembly is further used for receiving the induction signals of the acupuncture point sensors and displaying preset human tissue information of corresponding acupuncture points on the virtual training model according to the induction signals.

An aspect of the present invention relates to an acupuncture training method performed using the acupuncture training system, a user assisting training using the mixed reality assistance component, including:
