[0014] The specific implementation of the virtual surgery simulation method and device provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Firstly, a specific implementation of the virtual surgery simulation method of the present invention is given in conjunction with the accompanying drawings.

[0016] figure 1 Shown is a schematic flow chart of the virtual surgery simulation method provided in this specific embodiment, and then figure 1 The steps shown are described in detail.

[0017] S11: Perform a plain CT scan on the craniomaxillofacial area to obtain scanning data.

[0018] CT (Computer-aided Tomograph, computerized tomography) is a scanning method that uses computer technology to reconstruct the tomographic image of the measured object to obtain a three-dimensional tomographic image. CT plain scan refers to a continuous, non-interval, non-overlapping, spiral horizontal thin-slice scan. The th...

Abstract

The invention relates to the fields of digital medicine and computer-assisted surgery, and provides a virtual surgery simulation method and a device of the virtual surgery simulation method. The virtual surgery simulation method comprises the following steps of: (1) carrying out CT plain scanning on a craniomaxillofacial region to obtain scanned data; (2) carrying out three-dimensional reconstruction on bone tissue according to the scanned data by utilizing a computer, and simulating the operation of osteotomy to establish a dendritical structure model of a craniomaxillofacial bone; (3) carrying out bone block three-dimensional space observation at any angle of view on a virtual reality interactive operation platform by an operator who wears a pair of spectral separation stereo glasses to assist the operator in preoperative design; and (4) carrying out bone block three-dimensional space rotating and shifting simulation on the dendritical structure model of the craniomaxillofacial bone in a virtual reality space by the operator who wears a pair of data gloves, and producing real-time force feedback perception by a haptic feedback device which is connected with the computer to assist the operator in surgery simulation. The method and the device are strong in immersion and interaction, simple, efficient and easy to operate.

Description

technical field [0001] The invention relates to the fields of digital medicine and computer-aided surgery, in particular to a virtual surgery simulation method and device for designing and simulating orthognathic virtual surgery. Background technique [0002] Traditional orthognathic surgery design and simulation is based on cephalometric analysis or computer craniofacial contour Figure II Based on the three-dimensional plane, there are shortcomings of overlapping anatomical structures, information loss, two-dimensional data cannot fully reflect the three-dimensional structure, difficulties in making diagnosis and surgical plans, and unpredictable postoperative effects, especially for patients with facial asymmetry and complex deformities. However, the 3D surgical design and simulation software currently used in clinical practice can be operated on the 3D reconstruction model, but it is still displayed on the traditional 2D display screen, which limits the effect and signifi...
