Human body comprehensive puncture computer simulation training and assessment device

Abstract

The invention discloses a human body comprehensive puncture computer simulation training and assessment device; the human body comprehensive puncture computer simulation training and assessment devicecomprises a simulation computer system, three-dimensional virtual simulation software, a three-dimensional space tracking positioner, a puncture needle, and a medical comprehensive puncture rubber model. A 3D visualization technology is adopted, and an operator can observe the real-time posture and position of the puncture needle in a patient in a plurality of angles on a display, so that the operation of the puncture needle can be continuously corrected, and important tissue organs such as bones, fascia and blood vessels are avoided; the puncture operation is completed through the proper puncture path and the puncture depth; meanwhile, the skill key points such as the needle inlet point, the puncture angle, the puncture path, the puncture depth and the like can be prompted and guided informs of a graph, a color and a line and other visual forms; in addition, the device can further record the skill key points such as the needle inlet point, the puncture angle, the puncture path and the puncture depth of the puncture operation, so that the intelligent evaluation and assessment of the puncture skill are realized.

Description

technical field [0001] The invention relates to the technical field of clinical medicine teaching, in particular to a computer simulation training and assessment device for comprehensive human body puncture. Background technique [0002] In clinical medicine, it is often necessary to use puncture to remove body fluids from the body cavity for medical examination, inject drugs into the body cavity for clinical treatment, inject gas or contrast agent into the human body cavity for contrast examination, etc. Spinal puncture, thoracic cavity puncture, abdominal body cavity and organ puncture, bone marrow puncture, lymph node puncture, joint cavity puncture, blood vessel puncture, nasal cavity puncture, etc. Although there are some clinical practices of automated or robotic interventional puncture, however, manual puncture Surgery is still a very important medical clinical operation skill at present. In artificial puncture, medical staff generally avoid bones, fascia, blood vesse...

AI Technical Summary

Problems solved by technology

[0002] In clinical medicine, it is often necessary to use puncture to remove body fluids from body cavities for medical examination, inject drugs into body cavities for clinical treatment, inject gas or contrast agents into human body cavities for contrast examination, etc. Commonly used punctures include brain or Spinal cavity puncture, thoracic body cavity puncture, abdominal body cavity and viscera puncture, bone marrow puncture, lymph node puncture, articular cavity puncture, blood vessel puncture, nasal cavity puncture, etc. Although there are some clinical practices of automated or robotic interventional puncture, manual puncture Surgery is still a very important medical clinical operation skill at present. In manual puncture, medical staff generally avoid important tissues such as bones, fascia, and blood vessels based on the target points determined by medical images, combined with their own clinical experience, and according to the histological characteristics of organs. The organ then determines the needle entry point, puncture angle, puncture path, and puncture depth. This skill relies heavily on the practical experience and continuous improvement of medical staff. Conditions Repeated practice on the human body, generally using medical models for practice, currently all kinds of puncture models are rubber products, multiple cavities are set in the model and liquids of different colors are injected to simulate different areas, the operator uses this to judge the puncture The path and puncture effect. In fact, the operator cannot clearly understand the path of the puncture needle during the operation, and thus has no way of knowing whether important tissues and organs such as fascia and blood vessels are avoided during the puncture process, which is far from the clinical requirements. Large, the training effect is not good, and the current training methods cannot accurately record and automatically evaluate the puncture skills during the puncture skill assessment, and the degree of teaching automation is not high
