Embodiment 1

[0036] see figure 1 The planning method for three-dimensional simulated surgical nail placement provided by Embodiment 1 of the present invention includes the following steps:

[0037] S101. Perform three-dimensional modeling according to a received CT (Computed Tomography, computer tomography) image of the spine, to generate a three-dimensional model.

[0038] CT image is a technology to obtain the cross-section information of the object model by measuring the ray projection of the object at different angles, and what is obtained is a set of sliced ​​two-dimensional medical images in DICOM format.

[0039] In Embodiment 1 of the present invention, S101 may specifically include the following steps:

[0040] Convert CT DICOM image to BMP bitmap file;

[0041] Perform image smoothing on BMP bitmap files to filter out noise;

[0042] Perform sharpening and enhancement processing on the image after filtering the noise, so that the image of the bone part is enhanced;

[0043] S...

Embodiment 2

[0069] Embodiment 2 of the present invention provides a computer-readable storage medium, the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the three-dimensional simulated surgical nail placement as provided in Embodiment 1 of the present invention is realized. The steps of the planning method.

Embodiment 3

[0071] Figure 7 It shows a specific structural block diagram of the surgical simulator provided by Embodiment 3 of the present invention. A surgical simulator includes:

[0072] one or more processors 101;

[0073] memory 102; and

[0074] one or more computer programs, wherein said one or more computer programs are stored in said memory and configured to be executed by said one or more processors, said processors implementing said computer programs when executing said computer programs The steps of the planning method for three-dimensional simulated surgical nail placement provided by Embodiment 1 of the present invention.

Abstract

The invention is applicable to the field of medical instruments, and provides a planning method for screw placement of three-dimensional simulated operation and a surgical operation simulator. The method comprises the following steps: carrying out three-dimensional modeling according to a received CT image of the spine, thus generating a three-dimensional model; generating drawings of three sectioning planes according to the three-dimensional model; displaying the three-dimensional model and the drawings of the three sectioning planes of the three-dimensional model; adjusting the positions and sectioning directions of the sectioning planes, so that the section condition of the spine can be intuitively observed; determining a screw channel of a screw through the intersecting line of the sectioning planes in two directions; adding the screw in the determined screw channel; and moving the screw in the direction of the screw channel, so that the screw is at the position of the actual operation, and thus the planning for the screw is completed. According to the technical scheme, the planning is concise and convenient, and the screw channel can be accurately planned, so that the screw placement is safe and reliable.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a planning method for three-dimensional simulated surgical nail placement and a surgical simulator. Background technique [0002] The spine is the central axis of the human body, which mainly plays the role of support, protection, balance and movement. The spine is composed of vertebrae, intervertebral discs, spinal cord, spinal nerves, and autonomic nervous system. Inside the spine is the spinal canal, which houses and protects the spinal cord. Moreover, the 31 pairs of spinal nerves connected to the spinal cord exit the spinal canal through the intervertebral foramen and are protected by the spine. At the same time, the human aorta and neck arteries and veins are also distributed around the spine. [0003] Since the pedicle is adjacent to many blood vessels and nerve structures, once the screw is improperly placed and penetrates the lamina, the screw inserted by mistake will c...
