Problems solved by technology

[0003] Existing surgical guides need to print out 3D body surfaces such as figure 1 The area shown takes a long time to print. Some manufacturers manually reduce the printing area by "hollowing out" part of the layout during the design process of the guide plate. However, the printing effect will be affected, and it still cannot better meet the needs of puncture surgery. , therefore, the present invention proposes a fast 3D printing puncture surgical guide method to solve the deficiencies in the prior art

Embodiment 1

[0027] according to figure 2 As shown, this embodiment proposes a rapid 3D printing method for a puncture surgical guide, including the following steps:

[0028] Step 1: By using CT / MRI equipment to scan the patient, it is necessary to shoot multiple sets of CT / MRI medical images, and screen the obtained multiple sets of CT / MRI medical images to select a set of complete and standard information. CT / MRI medical images are used to obtain the specific location of lesions in the body and three-dimensional images of the patient's body surface;

[0029] Step 2: Based on the basis of medical diagnosis and the specific location of the lesion in the body obtained in Step 1 and the three-dimensional image of the patient's body surface, use the puncture design software to delineate the target area, and use the two-point positioning method to determine the puncture needle in the target area. The needle insertion position, direction and length of needle insertion need to avoid organs, bl...

[0038] according to figure 2 As shown, this embodiment proposes a rapid 3D printing method for a puncture surgical guide, including the following steps:

[0039] Step 1: By using CT / MRI equipment to scan the patient, it is necessary to shoot multiple sets of CT / MRI medical images, and screen the obtained multiple sets of CT / MRI medical images to select a set of complete and standard information. CT / MRI medical images are used to obtain the specific location of lesions in the body and 3D images of the patient's body surface

[0040] Step 2: Based on the basis of medical diagnosis and the specific location of the lesion in the body obtained in Step 1 and the three-dimensional image of the patient's body surface, use the puncture design software to delineate the target area, and use the two-point positioning method to determine the puncture needle in the target area. The needle insertion position, direction and length of needle insertion need to avoid organs, blood vessels, ner...

Embodiment 3

[0049] according to figure 2 As shown, this embodiment proposes a rapid 3D printing method for a puncture surgical guide, which is characterized in that it includes the following steps:

[0050] Step 1: By using CT / MRI equipment to scan the patient, it is necessary to shoot multiple sets of CT / MRI medical images, and screen the obtained multiple sets of CT / MRI medical images to select a set of complete and standard information. CT / MRI medical images are used to obtain the specific location of lesions in the body and 3D images of the patient's body surface

[0051] Step 2: Based on the basis of medical diagnosis and the specific location of the lesion in the body obtained in Step 1 and the three-dimensional image of the patient's body surface, use the puncture design software to delineate the target area, and use the two-point positioning method to determine the puncture needle in the target area. The needle insertion position, direction and length of needle insertion need to...

Abstract

The present invention disclosed a fast 3D printing and puncture operating board method, including using medical images to obtain the specific location of the lesion in the body and the three -dimensional images of the patient's body table;Level and surgical coverage; Calculate the shortest ground line between the needle inlet -direction cylinder position to form a guide plate main body; install the guidance tube component and fixed board to form a three -dimensional printing model; plan the 3D printing path;Printing the directional holes and its inter -connected lines (ground measurement lines) can form a puncture operating board architecture, the printing area is greatly reduced, and the printing path is optimized according to the ground testing line to achieve improvement of printing efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printing path planning, in particular to a rapid 3D printing method for a puncture surgical guide. Background technique [0002] In the puncture operation, in order to shorten the operation time, improve the operation accuracy, and reduce the patient's trauma and operation risks, the doctor plans the puncture path before the operation, and uses the 3D printing technology to make a needle guide plate to limit the puncture position and direction. The model is attached to the patient's body surface, and the patient is punctured according to the guide hole; [0003] Existing surgical guides need to print three-dimensional body surfaces such as figure 1 In the area shown, the printing time is long. Some manufacturers manually reduce the printing area by "hollowing out" part of the layout during the design of the guide plate, but the printing effect will be affected, and it is still unable to better meet th...
