Embodiment 1

[0059] A positioning and registration system for surgical navigation, such as figure 1 As shown, it includes: a processor 101 , a fixed positioning device 102 and a mobile positioning device 103 . Wherein, the fixed positioning device 102 and the mobile positioning device 103 are respectively connected to the processor 101 in communication. The communication connection may be a wired communication connection or a wireless communication connection. Wired communication connections are usually connected between devices through wired methods such as data lines and two-way or one-way data transmission, and wireless communication connections are usually connected between devices through wireless methods such as Wi-Fi, 4G mobile communication networks, and Bluetooth. Transfer data bidirectionally or unidirectionally.

[0060] The fixing and positioning device 102 is used to be fixed on the surgical object and obtain the position information of the fixed point, and send the position...

Embodiment 2

[0075] The positioning and registration system of this embodiment is basically the same as the positioning and registration system in Embodiment 1, the difference is that in the positioning and registration system of this embodiment, the processor selects The specific method of presetting the area is as follows:

[0076] The three-dimensional simulation image is displayed on the display screen, and the doctor uses an input device (such as a mouse, a touch pad, a keyboard) to select a point in the three-dimensional simulation image, and sets a preset number of feature points (such as 500 or 1000 ), and then, the processor 101 automatically takes the selected point as a reference point, takes the reference point as the center, and selects a preset number of feature points in the three-dimensional simulation image around the reference point, and the feature points form the A preset area, the shape of the preset area may be a circle, a rectangle or other irregular shapes.

Embodiment 3

[0086] The positioning registration system of this embodiment is basically the same as the positioning registration system in Embodiment 1, the difference is that in the positioning registration system of this embodiment, in order to quickly obtain a large number of positioning points, instead of point Selected method, use the following method to obtain the anchor point:

[0087] Continuously moving (such as sliding) the probe in the specified area (it is also necessary to ensure that both the surgical object and the probe are within the effective tracking range of the second optical dynamic tracking device), the first 2. The optical dynamic tracking device obtains real-time dynamic data when the probe moves through the positioning ball, extracts the multiple positioning points from the real-time dynamic data, and then sends the position information of the multiple positioning points through a communication connection to the processor 101.

[0088] At the same time, consideri...

Abstract

The invention discloses a positioning registration system and method for surgical navigation. The system includes a processor, a fixed positioning device and a mobile positioning device; the fixed positioning device is used for being fixed on a surgical object and obtaining position information of a fixed point; the processor is used for selecting a preset area and collecting position informationof multiple feature points in a three-dimensional analog image of the surgical object; the mobile positioning device is used for obtaining position information of multiple positioning points in a designated area; the processor is also used for calculating a fitting matrix of the multiple feature points and the multiple positioning points according to an iterative closet point algorithm and fittingthe fixed point into the three-dimensional analog image. According to the system and the method, through a scanning device, the three-dimensional analog image of the surgical object is obtained, andthe fixed point of the fixed positioning device and the positioning points of the mobile positioning device are mapped into the three-dimensional analog image to help doctors in observing surgical sites.

Description

technical field [0001] The invention relates to a positioning and registration system and method for surgical navigation. Background technique [0002] With the development of modern medical technology, the implementation of various operations has brought great progress to improve the treatment effect. However, the implementation of surgery often has certain difficulties and risks. In orthopedic surgery, the surgical site must be accurately determined, otherwise it is easy to cause surgical failure. [0003] The traditional method of determining the surgical site is that the doctor inserts the probe at the possible surgical site according to his own judgment, and then takes X-rays of the site where the probe is inserted, and then observes the position of the probe insertion and the actual operation according to the X-rays. The positional relationship of the parts, by inserting the probe multiple times and performing X-ray fluoroscopy, the surgical site is gradually identifi...
