Description

Technical Field

[0001] This utility model relates to the field of spinal surgery navigation technology, and more specifically, to a marker frame fixing device for a spinal surgery navigation system. Background Technology

[0002] In spinal surgery using a navigation system, accurately locating the patient's current position is a crucial step. To achieve this, a marker frame is typically attached to the patient's back. This marker frame serves as a reference point, aiding the surgeon in accurate navigation and manipulation during the procedure.

[0003] Currently, there are two main methods of fixation: one is to place the identification frame directly on the patient's back, and the other is to fix the identification frame with nails driven into the patient's bone. For the first method, placing the identification frame on the back requires the use of straps to secure it. However, this method has a significant problem: the straps can easily slip off the edge of the identification frame fixation plate. Once the straps slip, the identification frame may shift, which not only affects the precision of the surgery but may also lead to serious surgical risks. For the second method, fixing the identification frame with nails driven into the bone, while effectively avoiding the problem of identification frame displacement, it also has obvious disadvantages. This method causes additional trauma to the patient's back, increasing patient pain and recovery time. Furthermore, the nailing process itself carries certain risks and may lead to complications.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a marker frame fixing device for a spinal surgery navigation system to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A marker frame fixing device for a spinal surgery navigation system includes a fixed base plate, a fixing rod fixedly connected to the top of the fixed base plate, a marker frame body fixedly connected to the top of the fixing rod, a strap on the top of the fixed base plate, and raised edges on both sides of the fixed base plate.

[0008] Furthermore, in order to provide sufficient support area, the fixed base plate is rectangular in shape.

[0009] Furthermore, to ensure the strength and durability of the fixed base plate and the fixed rod, the fixed base plate and the fixed rod are made of high-strength aluminum alloy.

[0010] Furthermore, to aid in the positioning and tracking of the surgical navigation system, the marker frame body is equipped with multiple high-precision marker points, and the marker frame body is connected to the fixing rod by screws.

[0011] Furthermore, the strap width is 20-30mm.

[0012] Furthermore, there are two straps.

[0013] Furthermore, the number of curled edges is four.

[0014] The beneficial effects of this invention are as follows: By firmly connecting the fixed base plate, the fixed rod, and the identification frame body, a stable overall structure is formed. This connection method can not only withstand various external forces that may be generated during the operation, but also ensure that the identification frame remains in the correct position throughout the operation. In addition, by setting up raised edges around the fixed base plate, it can effectively prevent the straps from falling off the edges during the operation, avoid displacement of the identification frame, greatly reduce surgical risks, and improve the safety and efficiency of the operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] According to an embodiment of the present invention, a marker frame fixing device is provided for use in a spinal surgery navigation system.

[0022] Example 1

[0023] like Figures 1-2 As shown, the identification frame fixing device for a spinal surgery navigation system according to an embodiment of the present invention includes a fixing base plate 1. The fixing base plate 1 is rectangular in shape, which provides a larger contact area, enhances the friction between the device and the operating table or the patient's skin, and further improves the overall stability. A fixing rod 2 is fixedly connected to the top of the fixing base plate 1, and an identification frame body 3 is fixedly connected to the top of the fixing rod 2. The identification frame body 3 is provided with multiple high-precision marking points, which can be accurately identified and tracked by the surgical navigation system to ensure the accuracy of positioning during the operation. The identification frame body 3 is connected to the fixing rod 2 by screws, which facilitates disassembly of the identification frame body 3 while ensuring stability. The fixing base plate 1 and the fixing rod 2 are made of high-strength aluminum alloy. Using high-strength aluminum alloy to compose the fixing base plate 1 and the fixing rod 2 is not only lightweight but also sturdy, which can reduce the overall weight of the device while ensuring strength, thus reducing the burden on the patient. Two straps 4, each 20-30mm wide, are positioned above the base plate 1. This strap design ensures both comfort and effective fixation. The straps 4 can be wrapped in two ways: horizontally and vertically. Horizontal wrapping is suitable for wider patients, providing better fixation; vertical wrapping is suitable for longer patients, offering greater comfort. Users can choose the appropriate wrapping method based on the patient's specific needs to achieve optimal fixation and comfort. The base plate 1 has raised edges 5 around its perimeter. These edges effectively prevent the straps 4 from detaching during surgery, avoiding displacement of the marker frame and significantly reducing surgical risks.

[0024] In summary, by utilizing the above-mentioned technical solution of this utility model, a stable overall structure is formed by firmly connecting the fixed base plate 1, the fixed rod 2, and the identification frame body 3. This connection method can not only withstand various external forces that may be generated during the operation, but also ensure that the identification frame remains in the correct position during the operation. In addition, by setting up raised edges 5 around the fixed base plate 1, it is possible to effectively prevent the straps 4 from falling off the edges during the operation, avoid displacement of the identification frame, greatly reduce surgical risks, and improve the safety and efficiency of the operation.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
