Embodiment 1

[0037] This embodiment takes renal cyst puncture as an example, figure 1 It is a schematic flowchart of an anatomical projection method based on body surface vein features according to an embodiment of the present invention.

[0038] Step 1, in order to know the spatial relationship between the renal cyst and the body surface, first scan the human body with a tomography device to obtain a tomography image including body surface veins;

[0039] Conventional continuous tomography equipment includes CT and MRI. In this embodiment, CT is used to check renal cysts. Generally, scans are focused around target 2 during scanning, and body surfaces parallel to the scanning plane are generally not included in coronal and sagittal plane scans. Currently, there are body surface vein display devices that can display veins within 1 cm from the body surface. The thicker the diameter, the easier it is to observe. When taking pictures, the operator is required to scan the 1-3 layers of the bo...

Embodiment 2

[0055] It is basically the same as Example 1, except that the patient undergoes MRI examination. MRI examination can show the surface veins better than CT1.

Embodiment 3

[0057] This embodiment is similar to Embodiment 1, except that this embodiment is used for layer-by-layer positioning and projection during surgery. During the operation, the projected vein image coincides with the actual body surface vein 1 according to the body surface vein 1 model, and then the CT or MRI images of different levels are vertically projected on the operation area through the projector 5 fixed on the projection bracket 4, so that the body The table projection and the actual size of the human body are 1:1. During the operation, images of different levels can be called out according to the progress of the operation, and the surgeon can be reminded of the surrounding tissues, so as to improve the accuracy of the operation and reduce the secondary damage.

Abstract

The invention discloses an anatomical projection method based on body surface vein characteristics. Body surface veins are simultaneously scanned when CT and MRI target examinations are performed on apatient. A processed body surface vein image and an anatomical target tomographic image are both made into an anatomical model with the same size and coordinates. During the surgery, the model is projected onto a body surface, and the overlapping of the body surface vein model and the body surface veins is observed under a body surface vein display instrument, so that other anatomical structurescan be accurately positioned. During puncture, accurate puncture of targeTS can be achieved according to the body surface vein characteristics. During the surgery, a CT or MRI image is projected intoa surgical region by a projector to provide surgical accuracy and reduce subsidiary injury. The anatomical projection method has the advantages of being simple in structure, convenient to use, simplein operation and high in accuracy.

Description

technical field [0001] The invention relates to an anatomical projection method based on body surface vein features. Background technique [0002] The most important thing in surgery is to clarify the anatomical relationship. Doctors need to know what anatomical structures are around the cut tissue. However, on the operating table, they can only rely on experience and vague memory when reading images. Repeated recall and thinking are required. Anatomical abnormalities are also prone to additional damage. [0003] Although CT, MRI and other images in routine examinations are accurate, it is difficult to integrate them with the actual human body. Although B-ultrasound can flexibly adjust the image level, the image is blurred and the image display range is small. Puncture positioning requires the surgeon to have certain ultrasound knowledge, which limits its application. X-rays are radioactive, CT and MRI equipment are huge and expensive, CT is radioactive, and MRI prohibits...
