Introduction to Department Application

The lungs are one of the most complex organs in the human body. According to medical examinations such as CT or PET-CT scans The patient data obtained from the investigation is used to print a color and transparent patient lung model with the help of the WJP direct-injection color multi-material 3D printing technology of Saina, so that the doctor can have an accurate understanding of the entire organ and lesion before the operation, and shorten the exploration time during the operation , Choose the most suitable surgical path, clearly determine where the lesion is in the lungs, the direction of blood vessels around the lesion, etc., and perform the operation more accurately.

Detailed case

Apply for a hospital
Patient conditionLJH, 40 years old, male
Condition descriptionps=0 points, no history of smoking was admitted to the hospital because of "physical examination found a right middle lung nodule for more than 1 year", CT showed a ground glass nodule in the right middle lung, size 9*7mm. Past history: A heart murmur was found on a physical examination in 2003, and an echocardiogram in 2006 indicated "anterior mitral valve prolapse and severe mitral regurgitation".
Surgery difficultiesThe patient's mitral valve chordae rupture, severe regurgitation, and poor cardiac function. MDT has discussed that the pulmonary surgery time should not be too long, and FloTrac should be used for cardiac function monitoring during surgical anesthesia.
treatment planDuring the operation, 3D printing + MR positioning is used, and the virtual chest cavity is overlapped with the real chest cavity through gesture movement. Under MR navigation, perform percutaneous puncture positioning of the 3D printed guide. Positioning assisted downward VATS wedge resection.
advantageAccurate, short positioning time, less complications, not occupying much CT resources, positioning without radiation, without anesthetics
