Technical Field
The utility model belongs to image recognition and medical image processing field relate to a puncture operation positioning system under CT image guide.
Background
Puncture is a medical operation term, and is a diagnosis and treatment technology for puncturing a puncture needle into a body cavity to extract secretion for testing, injecting gas or contrast agent into the body cavity to perform contrast examination, or injecting medicine into the body cavity. The puncture aims at blood drawing test, blood transfusion, fluid infusion and angiography after being placed into a catheter. However, positioning during the puncturing process is very important, and if the positioning is not accurate, multiple puncturing results can be caused, so that the pain of a patient is greatly increased.
Mixed reality refers to a new visualization environment created by merging real and virtual worlds, where physical and digital objects coexist and interact in real time. The mixed reality needs to be realized in an environment capable of interacting with all objects in the real world, namely virtual reality if all the objects are virtual, and augmented reality if the displayed virtual information can only be simply superposed on the real objects. The combination of the advantages of the two is the final purpose of mixed reality. At present, the mixed reality technology is applied to clinic, which is beneficial to implementing accurate operation and greatly reduces the risk of the operation.

Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings, but should not be construed as limiting the present invention:
FIG. 1 is a schematic structural diagram of the present invention, as shown in the figure, a puncture surgery positioning system under the guidance of CT image comprises a real human body 1, a virtual human body 2, a real mark point 3, a virtual mark point 4, a virtual puncture needle 5, a mixed reality hardware device, HoloLens 6, and a console 7,
the real mark points 3 are fixedly arranged on the real human body 1 at a place which is not subjected to the change of the body position relative to the CT scanning or at a place which is not influenced by soft tissues on the body surface, and are used for determining the focus of a real patient in the operation environment and the position of the real patient 1: 1, superposing the reconstructed virtual three-dimensional models;
the virtual mark point 4 is fixedly arranged on the virtual human body 2, the position of the virtual mark point corresponds to the position of the real mark point 3 on the real human body 1, and the virtual mark point 4 is used for determining the position of the real mark point 1: 1, the reconstructed virtual three-dimensional model is superposed with a real patient focus;
the virtual puncture needle 5 is used for puncturing a virtual human body in a virtual image;
the mixed reality hardware equipment HoloLens 6 is worn on the head of an operator and is connected with the console 7 through a wireless network, and is used for assisting the operator to determine the position of a focus of a patient;
the console 7 is used for controlling the HoloLens 6 which is a mixed reality hardware device.
Before the surgery begins, the operator will follow the CT image 1: 1, projecting the reconstructed three-dimensional model on a real patient, and positioning the body surface by using the positioning mark points of the virtual model and the real positioning mark points of the patient, wherein the patient needs to keep a body position completely consistent with the body position of the patient in CT scanning. Marking points for body surface positioning require 1: 1 the virtual three-dimensional model reconstructed by the method does not generate artifacts in imaging under CT equipment, has stronger data quality, and can prevent the three-dimensional reconstruction process from being interfered by images. And selecting image data of the CT equipment acquired after the contrast agent is used and displayed more clearly.
The patient respectively pastes the mark points on the anterior superior iliac spines on two sides and the outer sides of thighs on two sides in the preoperative CT scanning. The operator wears the mixed reality glasses HoloLens with the mixed reality positioning system (software), and opens the patient 1 who completes reconstruction before the operation: and 1, projecting the virtual three-dimensional model on the body of the patient after the reconstructed virtual mark points and the real mark points are respectively in one-to-one correspondence by using a moving function in the positioning system. After the positioning point of the virtual space is successfully matched with the real positioning point, the virtual three-dimensional visualization result of the patient can be ensured to be matched with the real focus condition of the patient. After the matching is good, the operator can directly see the pre-made preoperative puncture needle input in the virtual influence, the operator can directly insert the puncture needle according to the input of the puncture needle, and the depth of the preoperative puncture needle can be measured in advance.
The utility model discloses utilize mixed reality technique can 1: 1 rebuild virtual three-dimensional model, the virtual probe that is the same as actual puncture probe is designed simultaneously, design puncture angle and degree of depth, puncture on virtual three-dimensional model through designing virtual pjncture needle, supplementary doctor punctures, improve the precision greatly, and three-dimensional visual permeable skin sees vascular distribution and calcification distribution, can effectually avoid the calcification to puncture, the misery that has alleviateed the patient greatly, the efficiency of the operation is improved, reduce the operation risk, reduce doctor-patient dispute, good commercial prospect and value have.
