Embodiment Construction

[0024] The present invention provides a virtual disinfection training system based on an entity model and a spatial positioning and tracking unit for displaying operation trajectories, wherein the entity model is based on the virtual model established by medical CT scanning human body data through numerical control processing, which completely corresponds to the virtual model, and the virtual The sterilized instruments (such as virtual sterilized tweezers) can be imaged by scanning the physical sterilized instruments with a 3D scanner, and also completely correspond to the physical sterilized instruments. The virtual model and the physical model coordinate system can establish a conversion relationship through the traditional three-point calibration method, so that the position of the physical model in the physical coordinate system is consistent with the position of the virtual model in the virtual coordinate system.

[0025] The solid sterilized tweezers hold the three-dimens...

Abstract

The invention discloses a virtual disinfection training system for displaying an operation track, comprising an entity model, a central processing unit, an operation unit and a display unit. The spatial positioning tracking module captures the coordinates of the spatial point of the simulation part in the physical coordinate system so as to establish the corresponding virtual point in the virtual coordinate system; and then obtains the running track of the virtual point on the virtual model surface through the central processing draw and render. The virtual sterilization training system of the present invention that displays the operation trajectory fills the blank of the current medical teaching aids field where there is no virtual training system for puncture sterilization, has a good and positive effect on improving the puncture sterilization operation of medical staff, and is beneficial to It forms standard operating habits in the training process.

Description

technical field [0001] The invention relates to a virtual disinfection training system for displaying an operation track, in particular to a virtual disinfection training system for displaying an operation track based on an entity model and a spatial positioning tracking unit. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity for blood testing, blood transfusion, infusion and catheter placement. Do an angiogram. Disinfection is one of the key steps in puncture techniques such as chest puncture, abdominal puncture, bone puncture, and lumbar puncture. If the disinfection operation is not standardized, the expected disinfection effect may not be achieved, resulting in the introduction of bacteria into the body during the puncture process...
