Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a three-dimensional positioning scale structure during surgery. Background Art

[0002] With the rapid development of medical technology, surgical procedures are moving towards minimally invasive and precise procedures. In many surgical fields, such as orthopedics and neurosurgery, accurate intraoperative positioning is a key element in ensuring surgical success and reducing patient trauma and complications. As a key instrument for achieving precise surgical positioning, the intraoperative three-dimensional positioning scale plays the important role of navigating surgical instruments and assisting doctors in determining the surgical path. Its performance directly determines the accuracy of surgical operations and patient outcomes. Therefore, continuously optimizing the structure and function of the positioning scale has become a key research direction in the medical field.

[0003] Existing intraoperative 3D positioning scales have numerous shortcomings in their structural design and functional implementation. From a structural perspective, traditional 3D positioning scales often utilize a single, flat or fixed-angle structure, making them difficult to adapt to the diverse positioning requirements of complex surgical scenarios. In complex orthopedic joint surgeries and deep neurosurgery procedures, the specific spatial location and angle of the surgical site make this fixed scale unable to provide an accurate and effective positioning reference. This makes it difficult for surgeons to accurately plan the surgical path, increasing the difficulty and risk of the procedure.

[0004] In terms of marking components, the imaging effect of marking components such as marking balls on existing positioning rulers is poor. On the one hand, the materials used have poor development effect under imaging equipment such as X-rays and CT, and the imaging is blurred. Doctors cannot accurately judge the position of the marking components based on the image, and thus it is difficult to determine the precise spatial coordinates of the surgical site. On the other hand, the way the marking components are fixed on the ruler body is not stable enough. During the operation, they are easily displaced or even fall off due to external forces such as vibration and collision generated by the operation of surgical instruments, resulting in positioning failure, which seriously threatens the safety and effectiveness of the operation.

[0005] To this end, we provide an intraoperative three-dimensional positioning scale structure to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a three-dimensional positioning scale structure for intraoperative surgery, which solves the problem that the three-dimensional positioning scales in the existing technology mostly adopt a single flat or fixed-angle structure, which is difficult to adapt to the diverse positioning requirements in complex surgical scenarios, and the imaging effect of marking components such as marking balls on the positioning scale is poor.

[0007] To solve the above technical problems, the present invention is implemented through the following technical solutions.

[0008] The present invention is an intraoperative three-dimensional positioning scale structure, comprising a three-dimensional C-scale main body, the three-dimensional C-scale main body having a 45-degree angle structure, a circular hole being provided on one side of the top of the three-dimensional C-scale main body, an aluminum ball being provided in the inner cavity of the circular hole, a positioning post being fixedly connected to the other side of the top of the three-dimensional C-scale main body, a three-dimensional C-scale tracer being fixedly connected to the top of the positioning post, positioning holes being provided at the four corners of the surface of the three-dimensional C-scale tracer, and reflective balls being provided in the inner cavity of the positioning holes.

[0009] The present invention is further configured such that the reflective ball is embedded in the inner cavity of the positioning hole, the bottom of the positioning hole is threadedly connected with a blocking cover, and one side of the blocking cover is in contact with the reflective ball.

[0029] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example 1

[0031] See also Figure 1-9The present invention is an intraoperative three-dimensional positioning scale structure, including a three-dimensional C-scale main body 1, which is a 45-degree angle structure. A circular hole 2 is provided on one side of the top of the three-dimensional C-scale main body 1, and an aluminum ball 3 is provided in the inner cavity of the circular hole 2. A positioning column 4 is fixedly connected to the other side of the top of the three-dimensional C-scale main body 1, and a three-dimensional C-scale tracer 5 is fixedly connected to the top of the positioning column 4. Positioning holes 6 are provided at the four corners of the surface of the three-dimensional C-scale tracer 5, and a reflective ball 7 is provided in the inner cavity of the positioning hole 6.

[0032] Specifically: The three-dimensional C-scale body 1 adopts a 45-degree angle structure, and the aluminum ball 3 is tightly embedded in the circular hole 2. The aluminum ball 3 is clearly visible under X-ray imaging and provides a key reference point for surgical positioning. The positioning column 4 adopts an inclined design, so that the three-dimensional C-scale tracer 5 fixedly connected to the top of the positioning column 4 forms a 45-degree angle with the three-dimensional C-scale body 1. Specifically, the through hole on the top of the positioning column 4 is fixed with a screw, which not only ensures that the three-dimensional C-scale tracer 5 is firmly installed, but also accurately realizes the fixation of the 45-degree angle between the two. The size of the positioning hole 6 is precisely adapted to the reflective ball 7. After the reflective ball 7 is embedded in the positioning hole 6, it is screwed and fastened from the bottom of the positioning hole 6 through the blocking cover 8 to ensure that the reflective ball 7 is in the hand. No displacement or falling off will occur during the operation. The 45-degree angle structure formed by the 3D C-scale main body 1 and the 3D C-scale tracer 5 breaks the plane layout limitation of the traditional scale. During the operation, it can provide the doctor with a positioning reference from multiple spatial dimensions. For complex surgical sites, this angle design can make the reflective ball 7 on the 3D C-scale tracer 5 reflect light at a better angle in the optical positioning system. Combined with the clear development of the aluminum ball 3 on the 3D C-scale main body 1 under X-ray, the two positioning methods complement each other, providing doctors with more comprehensive and accurate spatial information of the surgical site, helping doctors to plan the surgical path more accurately, and significantly reducing the difficulty of surgical operation and positioning error.

[0033] Example 2

[0034] See also Figure 1-9 On the basis of Example 1, the reflective ball 7 is embedded in the inner cavity of the positioning hole 6, and the bottom of the positioning hole 6 is threadedly connected to a plug cover 8, one side of the plug cover 8 is in contact with the reflective ball 7, the number of positioning posts 4 is two, and mounting holes 9 are opened on both sides of the top of the three-dimensional C-scale tracer 5, the mounting holes 9 are adapted to the positioning posts 4, and the mounting holes 9 and the positioning posts 4 are fixedly connected by screws. A reinforcing rib 10 is fixedly connected between the positioning posts 4, and one side of the reinforcing rib 10 is fixedly connected to the three-dimensional C-scale main body 1. The bottom of the circular hole 2 is threadedly connected to a plug 11, and the top of the plug 11 is in contact with the aluminum ball 3.

[0035] Specifically: the design of the reflective ball 7 embedded in the positioning hole 6 enables it to be accurately fixed on the three-dimensional C-scale tracer 5, ensuring that the reflective ball 7 is in the correct position in the optical positioning system, thereby providing an accurate reference for reflected light for surgical navigation and improving positioning accuracy. The bottom of the positioning hole 6 is connected to the plug cover 8 by a thread, and the plug cover 8 is in contact with the reflective ball 7. This structure can effectively prevent the reflective ball 7 from shifting or falling off due to external forces such as vibration and collision during the operation, ensuring the stability and reliability of the positioning information, avoiding positioning deviation caused by the change of the position of the reflective ball 7, and providing a strong guarantee for the smooth progress of the operation. The two positioning columns 4 and the three The mounting holes 9 on both sides of the three-dimensional C-scale tracer 5 cooperate to form a stable two-point support structure. Compared with a single positioning column 4, it can better disperse the external force on the three-dimensional C-scale tracer 5, and effectively enhance the stability of the connection between the three-dimensional C-scale tracer 5 and the three-dimensional C-scale main body 1. The setting of the reinforcing rib 10 further strengthens the connection strength between the two positioning columns 4, so that the positioning columns 4 and the three-dimensional C-scale main body 1 form a more stable overall structure, ensuring that the positioning scale always maintains accurate positioning performance. The plug 11 is connected to the bottom of the round hole 2 by a thread, which can firmly fix the aluminum ball 3 in the round hole 2 to prevent the aluminum ball 3 from being displaced or falling off during the operation.

[0036] Example 3

[0037] See also Figure 1-9 On the basis of Example 1, a connecting column 12 is fixedly connected to one side of the bottom of the three-dimensional C-scale body 1, the reflective ball 7 is made of high-reflectivity glass beads, and the surface of the reflective ball 7 is coated with a wear-resistant coating, the blocking cover 8 is made of medical-grade plastic, and a sealing rubber ring is provided at the threaded connection between the blocking cover 8 and the positioning hole 6.

[0038] Specifically: the connecting column 12 firmly connects the three-dimensional C-scale body 1 with the positioning sleeve at the end of the robotic arm trolley, so that the three-dimensional C-scale body 1 can be stably installed on the robotic arm trolley. This fixed connection method ensures that the three-dimensional C-scale body 1 will not loosen or fall off during the operation. The reflective ball 7 made of high-reflectivity glass microbead material can efficiently reflect light in the optical positioning system, so that the positioning system can capture the position information of the reflective ball 7 more clearly and accurately, significantly improving the positioning accuracy and sensitivity. The wear-resistant coating on the surface effectively enhances the wear resistance of the reflective ball 7 and extends its service life, ensuring that during a long operation, the reflective ball 7 always maintains good reflective performance and continues to provide a stable and reliable reference for surgical positioning. The plug cover 8 is made of medical-grade plastic material, which meets the hygiene and safety standards of medical equipment and avoids adverse effects on the operating environment and patients. The setting of the sealing rubber ring forms a good sealing effect at the threaded connection between the plug cover 8 and the positioning hole 6.

[0039] Example 4

[0040] See also Figure 1-9 On the basis of the first embodiment, the application scenario of the positioning scale structure also includes a robotic arm trolley, an operating table, a C-arm machine and a control console trolley. The three-dimensional C-scale body 1 is arranged at the end of the robotic arm of the robotic arm trolley, the operating table is arranged below the three-dimensional C-scale body 1, the C-arm machine is arranged on the other side of the operating table, and the control console trolley is arranged at the end of the operating table. The end of the robotic arm of the robotic arm trolley is fixedly connected to a positioning sleeve, the top of the control console trolley is fixedly connected to an adjustment frame, and one side of the adjustment frame is fixedly connected to a binocular camera.

[0041] Specifically: The body of the robotic arm trolley provides a stable support and mobile basis for the entire device, which is convenient for flexible adjustment of the position according to surgical needs in the operating room. The top robotic arm can perform multi-dimensional movements in three-dimensional space, and the positioning sleeve fixedly connected at its end provides a reliable installation carrier for the three-dimensional C-scale body 1. Through the flexible operation of the robotic arm, the three-dimensional C-scale body 1 can be accurately moved to the position and angle required for the operation to meet the positioning requirements in different surgical scenarios. The trolley body of the control console provides a stable placement platform for the entire control equipment. The adjustment frame on the top can flexibly adjust the position and angle of the binocular camera. The binocular camera can collect image information of the surgical site in real time and transmit it to the control equipment for processing and analysis. The key connection method can provide precise circumferential positioning between the connecting column 12 and the positioning sleeve, ensuring that the position and angle of the three-dimensional C-scale body 1 are accurate when it is installed at the end of the robotic arm trolley, thereby ensuring that the positioning information provided by the three-dimensional C-scale body 1 accurately corresponds to the actual position of the surgical site.

[0042] The working principle of the present invention is as follows: the three-dimensional C-scale body 1 adopts a 45-degree angle structure, and the aluminum ball 3 in the circular hole 2 on its top is clearly visible under X-ray imaging, providing a key reference point for surgical positioning. During surgery, the C-arm machine irradiates the surgical site with X-rays, and the position information of the aluminum ball 3 is recorded. The doctor can determine the coordinates of the surgical site in three-dimensional space based on this information. At the same time, the reflective balls 7 at the four corners of the surface of the three-dimensional C-scale tracer 5 are made of high-reflectivity glass beads. In the optical positioning system, the reflective balls 7 can efficiently reflect light. The binocular camera collects image information of the surgical site in real time. By analyzing the position of the light reflected by the reflective balls 7, more accurate spatial coordinate information of the surgical site is obtained. The 45-degree angle structure formed by the three-dimensional C-scale body 1 and the three-dimensional C-scale tracer 5 enables the reflective balls 7 to reflect light at a more optimal angle in the optical positioning system. The two positioning methods complement each other, providing doctors with comprehensive and accurate spatial information of the surgical site.

[0043] The body of the robotic arm trolley provides stable support for the entire device, and the end robotic arm can move in multiple dimensions in three-dimensional space. The positioning sleeve at its end is connected to the connecting column 12 at the bottom of the three-dimensional C-scale body 1 through a key connection. The positioning key on the surface of the connecting column 12 is tightly matched with the keyway on the inner wall of the positioning sleeve to achieve precise circumferential positioning, ensuring that the installation position and angle of the three-dimensional C-scale body 1 are accurate. At the same time, this connection method can withstand external forces such as vibration and torsion during surgery, ensuring that the three-dimensional C-scale body 1 is stably installed on the robotic arm trolley. The two positioning columns 4 are fixedly connected to the mounting holes 9 on both sides of the top of the three-dimensional C-scale tracer 5 by screws to form a stable two-point support structure. The reinforcing ribs 10 between the positioning columns 4 further strengthen the connection strength, so that the positioning columns 4 and the three-dimensional C-scale body 1 form a stable whole, preventing the structure from loosening or shifting due to external forces during surgery, and ensuring that the three-dimensional C-scale body 1 always maintains precise positioning performance.

[0044] The trolley body of the control console provides a stable placement platform for the control equipment, and the adjustment frame flexibly adjusts the position and angle of the binocular camera. The image information of the surgical site collected by the binocular camera and the X-ray image information obtained by the C-arm machine are transmitted to the control equipment for processing and analysis. The control equipment uses the image processing algorithm, combined with the position information of the aluminum ball 3 and the reflective ball 7, to construct a three-dimensional model of the surgical site, calculate the precise operation path of the surgical instrument, and feed back the relevant information to the doctor in real time. Based on this information, the doctor uses the robotic arm trolley to flexibly adjust the position and angle of the three-dimensional C ruler body 1, guide the surgical instrument to operate along the planned path, and achieve precise positioning and implementation of the operation.
