[0050] Image processing module: used to identify internal organs and blood vessels after importing CT images, generate a three-dimensional image, and reconstruct the lesion model by marking the lesion area;

[0051] Database module: used to store and record the data of the simulation system, and at the same time, relevant data can be retrieved in due course;

[0052] Display module: for displaying or 3D displaying the three-dimensional image generated by the image processing module;

[0053] Functional module: used to read the data stored in the database module, identify the structure, value and level of organs;

[0054] Tool module: virtual tools for volume calculation, measurement, cutting, puncture, and ablation of organs and lesions; ...

Embodiment 2

[0064] A preoperative planning simulation device based on a mixed reality preoperative planning simulation system;

[0065] The preoperative planning simulation device based on the mixed reality preoperative planning simulation system includes: Zspace hardware platform, image acquisition device, projection equipment, 3D glasses equipment and input operation equipment;

[0066] The Zspace hardware platform is a terminal machine, and the image acquisition device is connected to import image data by installing a capture card, and the projection equipment and input operation equipment are connected to the Zspace hardware platform through an optical cable. The 3D glasses equipment is 3D glasses. After adjusting to 3D mode for observation, the input operation device is connected to the Zspace hardware platform through USB.

[0067] Such as figure 2 As shown, the above-mentioned preoperative planning simulation device is based on the Zspace hardware platform, and is programmed and ...

Embodiment 3

[0069] A preoperative planning simulation method based on a mixed reality preoperative planning simulation system;

[0070] The preoperative planning simulation method based on the mixed reality preoperative planning simulation system comprises the following steps:

[0071] Step 1. Import and process CT data

[0072] Based on CT data, the data is imported through the image processing module. During the import process, the image processing module can identify the parameters of organs and surrounding large blood vessels and generate a three-dimensional pattern. However, the lesion area and small blood vessels need to be manually marked and input. , display the real reconstruction data of the patient, and view the relationship between the lesion and surrounding organs;

[0073] Step 2. Data storage for the database module

[0074] The imported database module is stored in the database module after format conversion, and the data in the database module is classified and stored; ...

Abstract

The invention discloses a preoperative planning simulation system, device and method based on mixed reality, and relates to the technical field of operation simulation. The preoperative planning simulation system comprises an image processing module, a database module, a display module, a function module, a tool module and a peripheral module. Meanwhile, in combination with the preoperative planning simulation system device related to hardware and based on mixed reality, CT data serves as the basis and is imported into the database module for three-dimensional reconstruction to obtain 3D visceral organs and peripheral structures, and visceral organ transparency, display hiding and color information adjustment are conducted by means of the functional module to distinguish structures, numerical values and levels; and meanwhile, virtual volume calculation, measurement, cutting, puncture and ablation are carried out on organs and focuses by means of the tool module according to the experience of an operator, an operation scheme and type are finally determined and stored, the optimal operation scheme is determined through preoperative virtual simulation, doctor-patient communication canbe visually carried out, and the purposes of shortening operation time and reducing operation risks are achieved.

Description

technical field [0001] The present invention relates to the technical field of surgery simulation, in particular to a mixed reality-based preoperative planning simulation system, device and method. Background technique [0002] Since the 20th century, minimally invasive surgery technology represented by laparoscopic technology has developed rapidly. Compared with traditional surgery, minimally invasive surgery has the advantages of less trauma, faster recovery, and shorter anesthesia time. Therefore, minimally invasive surgery has been widely used. And development. However, due to the characteristics of minimally invasive surgery itself, doctors can only see the local conditions in the patient's body through the endoscope, which greatly increases the difficulty of surgery for doctors, and the dependence on experience is higher than traditional surgery. For doctors, preoperative planning is very important. [0003] Mixed Reality (MR, Mixed Reality) refers to a new visual en...
