The device designs the navigation port cover sheet as a circular sheet structure with an opening, so that after the navigation frame is installed, the navigation frame can be directly flipped around to cover the navigation frame's clearance port, which is convenient and quick to operate. In addition, such a structural setting enables the navigation port cover sheet to completely and evenly cover the navigation frame's clearance port, preventing the navigation frame's position from becoming uneven, which is beneficial to the operation. The present invention's dedicated skull sheet structure for an intraoperative navigation frame is not limited to the description in the following embodiments.

[0021] Example 1:

[0022] This embodiment provides a special single cranial structure for intraoperative navigation. Figure 1-3 As shown, it includes a skull single body 1 and a navigation port covering piece 2. The skull single body 1 is used to cover the patient's body during neurosurgery navigation surgery. A navigation frame yielding opening 103 is opened on the skull single body 1 at the position of the patient's head. A rod through-hole 200 is set at the center of the navigation port covering piece 2, wherein the navigation port covering piece 2 is sutured and installed at the position of the navigation frame yielding opening 103 through the connecting part 3. The navigation port covering piece 2 can be completely covered by the navigation frame yielding opening 103 by flipping. The navigation port covering piece 2 adopts a circular structure and has an opening. The opening extends from the edge of the navigation port covering piece 2 along the radius direction of the navigation port covering piece 2 to the rod through-hole 200.

[0023] By adopting the above technical solutions:

[0024] When the device is in use, it can be covered on the patient before the navigation frame is installed. When the navigation frame is installed, the navigation port covering piece 2 is in an uncovered state. At this time, the navigation frame's yield opening 103 is fully open, and the doctor can install the navigation frame through the navigation frame's yield opening 103. After the installation is completed, the navigation port covering piece 2 is flipped over and bypassed from the opening to completely cover the navigation frame's yield opening 103. It can be seen that the device designs the navigation port covering piece 2 as a circular sheet structure with an opening. Therefore, after the navigation frame is installed, it can directly bypass the navigation frame and flip over to cover the navigation frame's yield opening 103. The operation is convenient and quick. In addition, such a structural setting enables the navigation port covering piece 2 to completely and flatly cover the navigation frame's yield opening 103, and there will be no uneven position of the navigation frame, which is beneficial to the progress of the operation.

[0025] Example 2

[0026] Based on Example 1, in this embodiment, the surface of the navigation port cover sheet 2 is located at the opening position, and an extension portion 202 is provided along the opening direction. The extension portion 202 is fan-shaped, so that one of the opening ends of the navigation port cover sheet 2 covers above the extension portion 202.

[0027] The thickness of the extension portion 202 is 1 / 2 of the thickness of the navigation port cover sheet 2 , and the thickness of the portion of the navigation port cover sheet 2 covering the extension portion 202 is consistent with the thickness of the extension portion 202 .

[0028] A first adhesive portion 102 is provided on the upper surface of the navigation frame yield opening 103, and a second adhesive portion 201 is provided on the lower surface of the navigation port cover sheet 2. When the navigation port cover sheet 2 completely covers the navigation frame yield opening 103, the first adhesive portion 102 and the second adhesive portion 201 correspond in position and adhere to each other, thereby ensuring that the navigation port cover sheet 2 is fixed.

[0029] The first adhesive portion 102 and the second adhesive portion 201 are both annular and are located at the edges of the navigation frame opening 103 and the navigation opening cover sheet 2 respectively.

[0030] By adopting the above technical solutions:

[0031] The opening positions of the navigation port cover sheet 2 form a mutually overlapping structure, thereby ensuring that the navigation port cover sheet 2 can completely cover the navigation frame yielding opening 103, and there will be no gaps at the opening. Moreover, when the navigation port cover sheet 2 is overlapped on the extension portion 202, the thickness of the overlapping position can be kept consistent with the navigation port cover sheet 2, further ensuring that the position of the navigation frame is not uneven, which is beneficial to the progress of the operation.

[0032] Example 3

[0033] On the basis of Example 1, in this embodiment, a nasal hole 100 is opened on the skull body 1 at the position of the patient's nose to provide nasal breathing for the patient.

[0034] The upper portion of the nose hole 100 is in an arc shape and arches upwards. A lower nose cutting seam 101 is provided below the nose hole 100 in a direction perpendicular to the nose.

[0035] By adopting the above technical solutions:

[0036] When the skull sheet is in use, the area above the nasal hole 100 will not completely press on the patient's nose, thereby reducing the patient's discomfort caused by nasal pressure. The setting of the lower nasal cutting seam 101 enables the nasal hole 100 to be lightly pressed against the patient's philtrum, so that the skull sheet at this position will not rise up and block the patient's breathing, thereby further reducing the patient's discomfort.
