Description

Technical Field

[0001] This utility model designs a quick-adjustment clip, and more particularly a quick-adjustment clip and a quick adjustment mechanism for a surgical stereo navigation system. Background Technology

[0002] Currently, head surgeries are time-sensitive, especially stroke surgeries which often require rapid and accurate puncture treatment. Existing surgical stereotactic navigation systems use adjustment mechanisms that are slow, delaying patient rescue time. Summary of the Invention

[0003] This invention provides a rapid adjustment mechanism for a surgical stereo navigation system, solving the problem of slow adjustment in surgical stereo navigation systems.

[0004] This utility model adopts the following technical solution: a quick-adjusting clamp, including an upper clamping bar and a lower clamping bar, one end of the upper clamping bar and the lower clamping bar are connected by a rotating shaft, and the other end of the upper clamping bar has a pressure ring for pressing the lower part of the lower clamping bar when the upper clamping bar and the lower clamping bar are fastened; the upper clamping bar is provided with a first half lock nut, and the lower clamping bar is provided with a second half lock nut, the first half lock nut and the second half lock nut are cut in half, and the first half lock nut and the second half lock nut are formed into a complete nut by the closing of the upper clamping bar and the lower clamping bar, forming a threaded channel.

[0005] Furthermore, the first half-lock nut is located in the middle of the upper clamping bar, and the second half-lock nut is located in the middle of the lower clamping bar.

[0006] Furthermore, the first half-lock nut is disposed on the upper clamping bar and close to the rotating shaft, and the second half-lock nut is disposed on the lower clamping bar and close to the rotating shaft.

[0007] Furthermore, the first half-lock nut is disposed on the upper clamping bar and away from the rotating shaft, and the second half-lock nut is disposed on the lower clamping bar and away from the rotating shaft.

[0008] Based on the lever principle, when the quick-adjusting clamp closes, the first and second half-lock nuts are positioned away from the pivot, resulting in lower clamping force and easier adjustment of their internal fittings, but the clamping is looser. Conversely, when positioned closer to the pivot, they exert greater clamping force, requiring more effort to adjust their internal fittings, but the clamping is tighter and more stable. Therefore, placing the first and second half-lock nuts in the middle is a better choice, but they can also be positioned at any position on the upper or lower clamping bar according to actual needs.

[0009] The quick-adjustment mechanism for a surgical stereoscopic navigation system, including the aforementioned quick-adjustment clip, also includes a bracket. The bracket is semi-circular, with positioning portions at both ends. Each positioning portion includes a positioning screw and a through hole on the bracket. The positioning screw is aligned with the center of the bracket through the through hole and the threaded channel. The quick-adjustment clip holds the positioning screw. With the quick-adjustment clip in use, when the clip is open, the positioning screw can be quickly and freely adjusted. After a rapid coarse adjustment, the clip clamps shut, and the positioning screw continues to rotate for further adjustment. This design ensures both rapid adjustment of the positioning screw and accurate adjustment, thus meeting the requirements of surgical procedures.

[0010] Compared with the prior art, the advantages of the rapid adjustment mechanism of this utility model for a surgical stereoscopic navigation system are as follows:

[0011] (1) When the quick-adjusting clamp is tightened, the first half lock nut and the second half lock nut close together to form a complete nut, forming a threaded channel, allowing the threaded meshing parts in the channel to be finely adjusted by rotation;

[0012] (2) When the quick-adjustment clamp opens, the first half lock nut and the second half lock nut separate, allowing the threaded engagement parts in the channel to be released. It is not restricted by the thread engagement and can be quickly and freely adjusted. Attached Figure Description

[0018] The specific implementation steps are described in detail below with reference to the accompanying drawings:

[0019] Example 1

[0020] like Figure 1This is an embodiment of a quick-adjusting clip 1 of the present invention, including an upper clip 1-1 and a lower clip 1-2. One end of the upper clip 1-1 and the lower clip 1-2 are connected by a rotating shaft 1-3. The other end of the upper clip 1-1 has a pressure ring 1-4 for pressing against the lower part of the lower clip 1-2 when the upper clip 1-1 and the lower clip 1-2 are engaged. A first half-lock nut 1-5 is provided on the upper clip 1-1 near the rotating shaft 1-3, and a second half-lock nut 1-6 is provided on the lower clip 1-2 near the rotating shaft 1-3. The first half-lock nut 1-5 and the second half-lock nut 1-6 are nuts cut in half. The first half-lock nut 1-5 and the second half-lock nut 1-6 are formed into a complete nut by the closing of the upper clip 1-1 and the lower clip 1-2, forming a threaded channel.

[0021] In this embodiment, the first half lock nut 1-5 and the second half lock nut 1-6 are relatively close to the rotating shaft 1-3.

[0022] Example 2

[0023] like Figure 2 This is an embodiment of a quick adjustment mechanism for a surgical stereo navigation system according to the present invention, including a quick-adjustment clamp 1 and a bracket 2 as described in Embodiment 1. The bracket 2 is semi-circular and has positioning parts at both ends. The positioning parts include positioning screws 3 and through holes provided on the bracket 2. The positioning screws 3 are aligned with the center of the bracket 2 through the through holes and the threaded channel of the quick-adjustment clamp 1, and the quick-adjustment clamp 1 clamps the positioning screws 3.

[0024] Example 3

[0025] like Figure 3 This is an embodiment of a quick-adjusting clip 1 of the present invention, including an upper clip 1-1 and a lower clip 1-2. One end of the upper clip 1-1 and the lower clip 1-2 are connected by a rotating shaft 1-3. The other end of the upper clip 1-1 has a pressure ring 1-4 for pressing against the lower part of the lower clip 1-2 when the upper clip 1-1 and the lower clip 1-2 are engaged. A first half-lock nut 1-5 is provided in the middle of the upper clip 1-1, and a second half-lock nut 1-6 is provided in the middle of the lower clip 1-2. The first half-lock nut 1-5 and the second half-lock nut 1-6 are nuts cut in half. The first half-lock nut 1-5 and the second half-lock nut 1-6 form a complete nut by the closing of the upper clip 1-1 and the lower clip 1-2, forming a threaded channel.

[0026] In this embodiment, the first half lock nut 1-5 and the second half lock nut 1-6 are located in the middle of the upper clamping bar 1-1 and the lower clamping bar 1-2.

[0027] Example 4

[0028] like Figure 4This is an embodiment of a quick-adjusting clip 1 of the present invention, including an upper clip 1-1 and a lower clip 1-2. One end of the upper clip 1-1 and the lower clip 1-2 are connected by a rotating shaft 1-3. The other end of the upper clip 1-1 has a pressure ring 1-4 for pressing against the lower part of the lower clip 1-2 when the upper clip 1-1 and the lower clip 1-2 are engaged. The upper clip 1-1 is provided with a first half lock nut 1-5 away from the rotating shaft 1-3, and the lower clip 1-2 is provided with a second half lock nut 1-6 away from the rotating shaft 1-3. The first half lock nut 1-5 and the second half lock nut 1-6 are nuts cut in half. The first half lock nut 1-5 and the second half lock nut 1-6 are formed into a complete nut by the closing of the upper clip 1-1 and the lower clip 1-2, forming a threaded channel.

[0029] In this embodiment, the first half lock nut 1-5 and the second half lock nut 1-6 are relatively far from the rotating shaft 1-3.

[0030] Based on the lever principle, when the quick-adjusting clamp 1 is closed, the first half-lock nut 1-5 and the second half-lock nut 1-6 are positioned away from the rotating shaft 1-3, resulting in a smaller clamping force and easier adjustment of the mating parts, but the clamping is relatively loose. Conversely, when the first half-lock nut 1-5 and the second half-lock nut 1-6 are positioned closer to the rotating shaft 1-3, they have a larger clamping force and require more effort to adjust the mating parts, but the clamping is tighter and more stable. The positions of the first half-lock nut 1-5 and the second half-lock nut 1-6 on the upper clamping bar 1-1 and the lower clamping bar 1-2 can be set according to requirements.
