Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the fact that the traditional method in the prior art needs to rely on the doctor's experience, the positioning is inaccurate, and it may also require multiple filmings to cause the patient to suffer too much radiation, while the new method such as orthopedic computer-aided navigation technology cannot quickly It reflects the patient's current surgical site well, so that doctors cannot intuitively understand the spatial position relationship between surgical instruments in real surgical scenes and the actual patient's anatomical structure, and it is easy to cause defects in wounds other than the surgical site.

Embodiment 1

[0030] Such as figure 1 As shown, this embodiment relates to a registration and registration system for surgical navigation, which includes: a control host 11, a first marking component 12, a second marking component 13, a positioning tracking device 14, and an image acquisition device 15, wherein , the positioning tracking device 14 and the image acquisition device 15 are respectively connected to the control host 11 in communication.

[0031] The first marking part 12 is attached to the skin of the surgical site for development during preoperative CT scanning to obtain CT data containing the pattern of the first marking part 12. The CT data is specifically a plurality of tomographic images, and the control host 11 can be based on these A three-dimensional model is generated from the tomographic image. It should be noted that the generated three-dimensional model and the scanned entity are simulated in a one-to-one ratio. Relative positional relationship.

Embodiment 2

[0047] Such as figure 2 As shown, the registration and registration method for surgical navigation in this embodiment includes the following steps:

[0048] 101. The first marking component is attached to the skin of the surgical site before the operation, and is developed during CT scanning to generate CT data. The CT data includes the information of the pattern of the first marking component, and the control host generates a three-dimensional model according to the CT data;

[0049] Further, the first marking component is a film, the film includes the same front pattern and back pattern, the front pattern includes the smear marks of barium sulfate material, the front pattern is developed during CT scanning, the film is peeled off after CT scanning, and the back pattern is printed on the skin A watermark pattern is formed on the image acquisition device to acquire the first position information by collecting the watermark pattern. In the specific implementation, the first m...

Abstract

The invention discloses a registration alignment system and method for operation navigation. The registration alignment system comprises a control engine, a first marking component, a second marking component, a location tracking device and an image capture device; CT data relative location information containing operation information and the first marking component is acquired through preoperative CT scanning, the image capture device is used for capturing the first marking component and the second marking component to acquire location information of the first marking component and the second marking component relative to the image capture device, the control engine is used for performing three-dimensional image reconstruction and registration alignment on the CT data in a location coordinate system according to pre-stored inter-location relation of the image capture device and the location tracking device in combination with the relative location information, the intra-operative location tracking device locates and tracks the second marking component in real time, and the control engine aligns a three-dimensional image dynamically according to real-time location tracking data. By the arrangement, the three-dimensional image high in precision, intuitive and easy to understand and aligned in real time can be obtained, and operation of doctors is facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a registration and registration system and method for surgical navigation. Background technique [0002] In surgery, especially orthopedic surgery, in order to identify the surgical site, a traditional method is to rely on the doctor's years of surgical experience to determine the surgical site, place positioning pins on the patient, and then use an X-ray fluoroscopy machine to take X-rays. To obtain the perspective view of the transverse section and the longitudinal section, and correct the position of the positioning needle accordingly, this method requires the doctor to have a lot of experience and has high requirements for the doctor. Therefore, the promotion and application of the operation has certain limitations, and this method This method of relying on the doctor's experience to determine the surgical site is uncertain and has certain risks. Once the positioning is inaccur...
