Problems solved by technology

If these fluoroscopic images are not used, and the fluoroscopic exposure is re-performed in the next interventional operation, it will undoubtedly cause a waste of medical resources
[0004] 2. Excessive Radiation Exposure
[0005] 3. Low surgical positioning efficiency
Every time fluoroscopy positioning is performed, the doctor needs to constantly observe the fluoroscopy images and locate the surgical site based on his own clinical experience. This is a very technically difficult and time-consuming task

Embodiment 1

[0042] Such as figure 1 As shown, the embodiment of the present invention provides a perspective navigation map system, which includes a storage module 100 , an update module 200 , a search module 300 and a human-computer interaction module 400 .

[0043] The storage module 100 is used for storing the information of the patient's fluoroscopic images to form a fluoroscopic navigation map. It includes a map library 101 and a part library 102 .

[0044] During clinical interventional operations, each anatomical structure of the human body corresponds to different positions of the fluoroscopy platform, and the map library 101 is divided into multiple regions according to the fluoroscopy platform, and anatomical objects are determined according to the corresponding human anatomical structure of each region. Each anatomical object is a tree structure formed according to human cognition, and has its corresponding root unit. Each root unit can contain multiple levels of subunits. T...

Embodiment 2

[0053] An embodiment of the present invention provides a method for generating a perspective navigation map, which includes: generation of an initial perspective navigation map and instantiation of anatomical objects.

[0054] Such as image 3 As shown, the anatomical structure of the human body corresponds to different positions of the fluoroscopy platform, and the storage module is divided into multiple regions according to the fluoroscopy platform, and the regions include anatomical objects determined according to the anatomical structure, and the anatomical objects include root units. The root cell contains child cells, forming the initial perspective navigation map.

[0055] The initial perspective navigation map consists of a number of initial anatomical objects. The various anatomical structures inside the initial anatomical object are abstracted when the initial perspective navigation map is formed, and they have no definite position coordinates, but only the topologi...

Embodiment 3

[0066] Such as Image 6 As shown, in actual use, the process of using the perspective navigation map for positioning includes searching for information on anatomical objects, and the steps are as follows:

[0067] A. Input the information of the object to be located through the human-computer interaction module, and the human-computer interaction module will pass the information of the object to be located to the search module;

[0068] B. The search module searches the information of the storage module according to the information of the object to be located, and obtains the location information of the located object;

[0069] C. The search module transmits the position information of the positioning object to the human-computer interaction module;

[0070] D. The human-computer interaction module outputs the position information of the positioning object.

[0071] In step A of the embodiment of the present invention, the object information to be positioned may be input thr...

Abstract

The invention discloses a perspective navigation map system, a generation method and a positioning method. The perspective navigation map system comprises a storage module, an updating module, a search module and a man-machine interaction module, wherein the storage module comprises a map library; the map library comprises a plurality of areas divided by according to a perspective bed table; each area comprises a dissection object determined by according to a dissection structure; each dissection object comprises a root unit; each root unit comprises subunits; the updating module is used for updating information stored in the storage module; the search module is connected with the storage module and is used for searching information of the storage module; the man-machine interaction module is connected with the search module and is used for operating the system and displaying the information. According to the perspective navigation map system provided by the invention, a doctor is enabled to obtain positioning information in a surgical procedure in time; the information can be archived for calling by the doctor during surgery at any time; the information can be continuously updated by a perspective exposure image acquired during each interventional operation, the accuracy of position information of a patient body part is continuously improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a perspective navigation map system for clinical interventional operations, a method for generating the perspective navigation map, and a method for positioning by using the perspective navigation map. Background technique [0002] In the case of clinical interventional surgery, doctors need to perform perspective exposure on the patient's body to determine the specific location of the interventional surgery site. After an interventional operation, the fluoroscopic exposure image during the surgical positioning process loses its use value. In the next interventional operation, the patient still needs to perform fluoroscopic exposure for interventional surgical positioning again. The problems of this application mode are as follows: [0003] 1. Waste of medical resources. Each fluoroscopic exposure is an image with certain clinical value obtained through con...
