Problems solved by technology

During the operation, most of the patients’ skull prosthesis and bone window surface will have a certain offset when they are fitted and fixed, and there will be a certain error, or even completely reversed, which prolongs the operation time. It does not match the preoperative design, and it also affects the effect of the operation. In some serious cases, it is likely to require reoperation

Embodiment Construction

[0027] In order to better understand the technical solutions of the present invention, further description will be given below with reference to the drawings and specific embodiments.

[0028] The patient's skull was injured, and the injury was a large-area injury, and the trauma area was about 120mm × 120mm. According to the invention of the method, the skull defect was repaired, and the process was as follows:

[0029] 1. The patient sticks a positioning marker block with a diameter of 3 mm on the head ( figure 2 ) after performing a CT scan to obtain the DICOM format data of the patient's head;

[0030] 2. Perform CT (Computed Tomography) or MR (Nuclear Magnetic Resonance) on the patient's skull, including the marking block on the surface of the scalp, and input the data in DICOM format into the computer. range should contain the range of the block marked in step 1;

[0031] 3. During the design process of the defect restoration, according to the position of the marker b...

Abstract

The present invention provides a method for positioning defective bone restorer of human body and skull defect position in surgery with the guiding of navigator through designing a spatial positioning mark. The possibility of surgery failure caused by the error placing position of restorer can be reduced through the method of the invention. The restorer can be accurately positioned through the spatial positioning mark, the skull model which is provided with the positioning mark, the restorer mark provided with positioning, DICOM data which has marked ball output, and the navigator which can read out the DICOM data.

Description

technical field [0001] The invention relates to a method for assisting doctors in positioning the prosthetic body in the human skull during cranioplasty, in particular, placing and fixing the personalized cranial prosthetic body made by computer three-dimensional modeling on the human skull defect precisely through surgery method of parts. Background technique [0002] Due to accidents, diseases and other reasons, the bones are severely damaged and osteonecrosis, so there must be an object to replace the bones to protect and support the human body. The use of computer three-dimensional modeling method to shape the restoration is also a hot spot in research. [0003] There are many methods for preparing bone prostheses, some of which can provide patients with high-precision bone prostheses that meet their individual needs, such as a titanium alloy for human bone defects introduced by Chinese invention patent CN200710044256.2. The restoration method can obtain a titanium all...
