[0024] The specific embodiments of the utility model will be described in detail below in combination with the drawings.

[0025] As Figures 1-2 Indicated, the utility model discloses a head navigation positioning device, it includes positioning frame 100, optical navigation assembly 200 and magnetic navigation assembly 300, positioning frame 100 includes clamping skull piece 101 and hooking nose piece 102, clamping skull piece 101 is used to hold in head, the first end of hooking nose piece 102 is installed on clamping skull piece 101, the second end of hooking nose piece 102 extends and hooks in the tip of the nose, optical navigation assembly 200 is installed on clamping skull piece 101, and optical navigation assembly 200 includes cross plate 201 and four reflective pieces 202 that are installed on four end portions of cross plate 201 respectively, and magnetic navigation assembly 300 is installed on clamping skull piece 101.

[0026] Specifically, the positioning frame 100 can be adapted to the head shapes of different patients. Specifically, the skull clamp 101 is adapted to the patient's head shape. The skull clamp 101 and the nose hook 102 are both made of elastic materials, and the structural shapes of the skull clamp 101 and the nose hook 102 are ergonomically designed according to the patient's head shape and facial shape. When different patients wear the head navigation positioning device, the skull clamp 101 can be quickly worn on the patient's head through the elastic properties of the skull clamp, and the nose hook 102 is along the patient's nose bridge and hooked at the tip of the nose to achieve rapid positioning. At this time, the positioning of the patient's head position is completed. Due to the elastic properties of the skull clamp 101 and the nose hook 102, different head shapes of different patients can be adapted. Then, the patient is navigated through the optical navigation component 200 and the magnetic navigation component 300. Among them, the reflective component 202 includes a reflective ball, which is made of professional high-light reflective material and has excellent reflective performance. In optical navigation systems, these reflective balls can reflect light-emitting diodes (such as infrared light) and produce a bright signal, allowing optical locators to accurately track their position.

[0027] Furthermore, the cross plate 201 is mounted on the skull clamp 101 and placed at the connection between the nose hook 102 and the skull clamp 101 .

[0028] The magnetic navigation assembly 300 includes a mounting tube 301 and a magnetic navigation component. The mounting tube 301 is mounted on the skull clamp 101 and away from the nose hook 102 . The magnetic navigation component (not shown) is loaded in the mounting tube 301 .

[0029] The skull clamp 101 includes a U-shaped clamp 1011 , and both ends of the U-shaped clamp 1011 are provided with ear supports 1012 .

[0030] Specifically, in actual clinical application, after the patient wears the head navigation positioning device, in order to ensure the firmness of the wearer, the staff will use medical desensitizing tape for auxiliary adhesion, such as the attached Figure 1 As shown, the overall structure of the U-shaped clamp 1011 is similar to that of glasses. Ear supports 1012 are provided at the two ends of the U-shaped clamp 1011 to better fit the patient's head according to ergonomics and improve wearing comfort. It should be noted that the end position of the ear support 1012 is provided with a threading hole, and the two ear supports 1012 can be connected at this position by using an elastic band or other connecting components to achieve circumferential wrapping of the patient's head, further providing a firm fixation.

[0031] Furthermore, a hook 1021 is provided on the second end of the nose hook piece 102, and the hook 1021 is used to hook the tip of the nose.

[0032] Specifically, it should be noted that the second end of the nose hook 102 is also provided with a positioning hole, and the position of the positioning hole is used to position the tip of the patient's nose. Since the positioning points of the head navigation positioning device are selected as three fixed points of the ears and the tip of the nose and one stable point of the bridge of the nose, any patient using the head navigation positioning device only needs to be calibrated at the first time of use, and can be used after wearing in the subsequent use process. This is a common headgear, and there is no need to customize it for patients, which is convenient, efficient and universal.

[0033] Further, the cross plate 201 includes four plate strips 2011 of different lengths, and the four plate strips 2011 are connected with each other and arranged at the connection between the nose hook 102 and the skull clamp 101.

[0034] As shown in the accompanying drawings, Figure 1 the plate strip 2011 with the shortest length is vertically arranged and extends along the bridge of the nose, and the lengths of the other plate strips 2011 increase in turn in the form of counterclockwise circumferential arrangement.

[0035] The above is one or more embodiments provided in combination with specific contents, and it is not intended that the specific implementation of the utility model is limited to these descriptions. Any approximation, similarity or replacement of the method and structure of the utility model, or any technical deduction or replacement under the concept of the utility model, should be regarded as the protection scope of the utility model.
