Construction method for digitized virtual hand and longitudinal shaped severed finger anatomic structure model

Abstract

The invention discloses a method for constructing anatomical structural models for a virtual hand and a longitudinally amputated finger. The method comprises the following steps: A. specimen selection and pretreatment; B. specimen irrigation; C. CT scan and data set acquisition; D. 3D visual reconstruction of a hand with Mimics software of Materalise Company of Belgium on a platform of a common personal computer; and E. digital virtual construction of a longitudinally amputated finger. The invention applies a virtual hand constructed by a digital virtual technology to clinic anatomical research of longitudinally amputated fingers (palms) and provides the method for constructing the anatomical structural models for the virtual hand and the longitudinally amputated finger which converts 2D images commonly used in clinic into 3D images, thereby improving the understanding of the structure of a hand and providing scientific foundation for clinic diagnosis and treatment protocol decision, surgeries, prognosis, etc.

Description

technical field [0001] The invention relates to a method for constructing digital virtual human organs, in particular to a method for constructing a digital virtual hand and a longitudinal severed finger anatomical structure model based on it. Background technique [0002] Digital virtual technology has become a hot issue in the field of life science and information science. Since the U.S. National Library of Medicine first proposed the "Visible Human Project (VHP)" in 1989, South Korea, Japan and other countries have also proposed similar research projects. Digital virtual human body refers to the digitization of human body structure, and through computer technology and image processing technology, a seemingly real simulated human body appears on the computer screen. At present, the research on "virtual human" at home and abroad is in the stage of "virtual visual human", which can also be called "virtual anatomical human" or "virtual geometric human". The goal is to virtua...

Problems solved by technology

[0008] Considering the thickness of the material to be cut, the gap between the blades is adjusted, and the angles at which the injured hand is brought into the cutting machine are different, so that the planes of the joints of the injured finger are different in depth, and the cutting surface of each finger may not be on the same level, so the cut will be uneven. There are various bone and joint, tendon, blood vessel and nerve injuries, including oblique, longitudinal, and multiple severed injuries, so the tissue repair of longitudinal severed fingers on the coronal plane can repair bones,
