Embodiment 1

[0053] like Figure 1-5 As shown, a positioning marking device for surgical navigation according to the present invention includes at least one positioning strap 1 .

[0054] like Figure 1-2 As shown, the positioning strap 1 includes:

[0055] The positioning strap body is a non-stretchable flexible strap. Those skilled in the art can understand that the positioning strap can be made of non-stretchable non-woven fabric, or other suitable materials.

[0056] A plurality of hollow points 2, the plurality of hollow points 2 are arranged on the positioning strap body in a plurality of groups; each of the plurality of hollow points has a positioning needle suitable for use in surgical navigation. A first surface to be joined, a second surface adapted to fit with the body surface of the strap fixing part, and a through hole passing through the first surface and the second surface, such as Figure 3-5 shown.

[0057] Fixing device 3, the fixing devices are arranged at both ends...

Embodiment 2

[0068] like Image 6 As shown, a registration system for surgical navigation according to the present invention includes:

[0069] The positioning marker device for surgical navigation according to any one of the above Embodiment 1 is fixed on the body surface of the patient P; and

[0070] A positioning needle, the positioning needle includes:

[0071] a body portion 10 having a shape extending along a longitudinal axis;

[0072] One end of the tip portion 20 is connected with one end of the main body portion, and the other end extends along the axis to form a needle tip.

[0073] In at least one embodiment, when the first surface of the positioning marking device is combined with the tip portion of the positioning needle, the axis of the positioning needle passes through the through hole of the positioning marking device.

[0074] In at least one embodiment, when the first surface of the positioning marking device is combined with the tip portion of the positioning needle...

Embodiment 3

[0077] The present invention also provides a body surface registration method for a surgical navigation system using the registration system of the above embodiments, including:

[0078] In the first positioning step, a positioning marking device for surgical navigation is placed on the body surface, and the position of the positioning marking device is fixed by a fixing device;

[0079] marking step, marking on the body surface according to the hollow point of the positioning marking device;

[0080] Scanning step, maintaining the position of the positioning marker device on the body surface and performing CT scanning;

[0081] a first removing step, removing the positioning marking device;

[0082] In the second positioning step, the positioning marking device is placed on the body surface according to the skin marking point, and fixed by a fixing device;

[0083] In the point-taking step, the tip of the positioning needle is used to sequentially engage with the first surf...

Abstract

The invention relates to a body surface positioning method for infrared navigation. The body surface positioning method for infrared navigation comprises the steps that a positioning and marking device for operation navigation is placed on the body surface, and the position of the positioning and marking device is fixed through a fixing device; according to hollow-out points of the positioning andmarking device, marking is conducted on the body surface; the position of the positioning and marking device on the body surface is kept, and CT scanning is performed; the positioning and marking device is removed and is placed on the body surface according to a skin marking point and is fixed through a fixing device; the sharp end of a positioning needle is sequentially connected with the firstsurfaces of the positioned and marked hollow-out points, then space coordinates of the sharp end of the positioning needle are determined, and images obtained through CT scanning are registered with an operation navigation system according to the positions in the images obtained through CT scanning conducted on the positioned and marked hollow-out points and positioning of the sharp end of the positioning needle when the positioning needle is connected with the hollow-out points.

Description

technical field [0001] The invention relates to a body surface positioning method and corresponding equipment for infrared navigation, belonging to a positioning and registration method and equipment of a surgical navigation system. Background technique [0002] With the continuous development of imaging interventional technology in recent years, the minimally invasive, accurate and effective interventional therapy under infrared navigation has played a greater role in the treatment of tumors and other diseases, and its application range has become wider and wider. Minimally invasive interventional technology is implemented under infrared navigation, using minimally invasive interventional instruments such as biopsy needles, catheters, radio frequency needles, etc., to insert therapeutic instruments or drugs into the target lesion tissue with minimal trauma for physical, mechanical or chemical treatment. Image navigation-assisted positioning and puncture system integrates im...
