Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a positioning puncture device for neurosurgery. Background Art

[0002] Neurosurgery is a branch of surgery that, based on surgery as the primary treatment method, applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related accessory structures such as the skull, scalp, cerebral blood vessels, and meninges. It investigates the causes and pathogenesis of diseases such as epilepsy, Parkinson's disease, and neuralgia, and explores new diagnostic, treatment, and preventive technologies.

[0003] However, most existing puncture devices have a very simple structure. When using them, the doctor needs to manually install the puncture device onto the positioning operating table. If an error occurs during the installation process and the puncture device becomes unstable, it will affect the surgical procedure and cause unnecessary pain to the patient. Furthermore, the positioning adjustment requires the doctor to manually adjust it repeatedly to determine the puncture point, which consumes a lot of time and effort. Utility Model Content

[0004] The purpose of this invention is to provide a positioning puncture device for neurosurgery, which aims to effectively solve the problems of most existing puncture devices having overly simple structures, requiring the surgeon to manually install the puncture device onto the positioning operating table, and causing instability of the puncture device due to errors during installation, thus affecting the surgical procedure and causing unnecessary pain to the patient. Furthermore, positioning adjustment requires repeated manual adjustments by the surgeon to determine the puncture point, which consumes a lot of time and effort.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A neurosurgical positioning puncture device includes an operating table. A control panel is fixedly connected to one side of the operating table, and a guide rail is fixedly connected to another side of the operating table. A slider is slidably connected inside the guide rail. A first drive mechanism is provided between the slider and the guide rail. An L-shaped support rod is fixedly connected above the slider. An extension rod is slidably connected to the other end of the L-shaped support rod. A second drive mechanism is provided between the extension rod and the L-shaped support rod. A sleeve is fixedly connected to the end of the extension rod away from the L-shaped support rod. A puncture needle is inserted into the sleeve. An infrared positioning light is fixedly installed below the extension rod and near the puncture needle. Due to the threaded connection between the first screw and the slider, the rotation of the first screw drives the slider, the L-shaped support rod, and the puncture needle to perform automatic lateral positioning adjustment. The extension rod can extend and retract along the L-shaped support rod, allowing the puncture needle to be adjusted longitudinally. The infrared positioning light, in conjunction with the extension rod, enhances the effectiveness of positioning puncture.

[0007] As a preferred embodiment of the present invention, the first driving mechanism includes a first servo motor fixedly mounted on one side of the guide rail, the output end of the first servo motor extending into the interior of the guide rail and fixedly connected to a first screw, and the slider being threadedly connected to the first screw.

[0008] As a preferred embodiment of this utility model, the second drive mechanism includes a second servo motor fixedly installed above the L-shaped support rod, and a second screw is threadedly connected to the end of the extension rod away from the sleeve. A transmission component is provided between the second screw and the second servo motor.

[0009] In a preferred embodiment of the present invention, the transmission assembly includes a first gear fixedly connected to the output end of the second servo motor, and a second gear fixedly connected to the end of the second screw away from the extension rod, wherein the second gear meshes with the first gear.

[0010] In a preferred embodiment of this utility model, a support shaft is coaxially fixedly connected to the side of the second gear away from the second screw, and the other end of the support shaft is rotatably connected to the inner wall of the L-shaped support rod.

[0011] In a preferred embodiment of this utility model, a limiting plate is fixedly connected to the end of the extension rod away from the sleeve, and the limiting plate is engaged with the inner port of the L-shaped support rod.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] (1) In order to improve the convenience of patient positioning and puncture in neurosurgery, the first servo motor can be activated according to the control panel. The first servo motor can drive the first screw to rotate forward or reverse. Due to the threaded connection between the first screw and the slider, the first screw rotates while driving the slider, L-shaped support rod and puncture needle to perform automatic positioning adjustment in the lateral direction. The extension rod can extend and retract along the L-shaped support rod to make the puncture needle perform longitudinal adjustment. Combined with the infrared positioning lamp, the effect of positioning and puncture is improved.

[0014] (2) The second servo motor is activated to drive the first gear to rotate. While the first gear rotates, it drives the meshing second gear to rotate. While the second gear rotates, it drives the second screw to rotate coaxially. Due to the threaded connection between the second screw and the extension rod, the second screw can drive the extension rod to extend or retract longitudinally along the L-shaped support rod while rotating, which further improves the adjustable positioning range of the puncture needle.

[0023] Example:

[0024] Please see Figure 1 and Figure 2 A neurosurgical positioning puncture device includes an operating table 1. A control panel 16 is fixedly connected to one side of the operating table 1. A guide rail 2 is fixedly connected to one side of the operating table 1. A slider 5 is slidably connected inside the guide rail 2. The guide rail 2 limits the slider 5 to ensure the stability of the slider 5 when sliding along the guide rail 2. A first driving mechanism is provided between the slider 5 and the guide rail 2. The first driving mechanism includes a first servo motor 3 fixedly mounted on one side of the guide rail 2. The output end of the first servo motor 3 extends into the interior of the guide rail 2 and is fixedly connected to a first screw 4. The slider 5 is threadedly connected to the first screw 4. The first servo motor 3 can drive the first screw 4. Whether rotating forward or backward, due to the threaded connection between the first screw 4 and the slider 5, the first screw 4 rotates while driving the slider 5 to move automatically. An L-shaped support rod 6 is fixedly connected above the slider 5, and an extension rod 7 is slidably connected to the other end of the L-shaped support rod 6. A second drive mechanism is provided between the extension rod 7 and the L-shaped support rod 6. A sleeve 13 is fixedly connected to the end of the extension rod 7 away from the L-shaped support rod 6. A puncture needle 14 is inserted into the sleeve 13. An infrared positioning light 15 is fixedly installed below the extension rod 7 and on the side close to the puncture needle 14. The puncture point of the puncture needle 14 is located according to the infrared positioning light 15, thereby improving the positioning efficiency.

[0025] Specifically, in order to improve the convenience of patient positioning and puncture in neurosurgery, the first servo motor 3 can be activated according to the control panel 16. The first servo motor 3 can drive the first screw 4 to rotate forward or backward. Due to the threaded connection between the first screw 4 and the slider 5, the rotation of the first screw 4 drives the slider 5, the L-shaped support rod 6 and the puncture needle 14 to perform automatic positioning and adjustment in the lateral direction. In addition, the extension rod 7 can extend and retract along the L-shaped support rod 6 to allow the puncture needle 14 to be adjusted in the longitudinal direction. The infrared positioning lamp 15 is used to improve the effect of positioning and puncture.

[0026] Please see Figure 3 The second drive mechanism includes a second servo motor 8 fixedly mounted on the top of the L-shaped support rod 6. A second screw 11 is threadedly connected to the end of the extension rod 7 away from the sleeve 13. A transmission assembly is provided between the second screw 11 and the second servo motor 8. The transmission assembly includes a first gear 9 fixedly connected to the output end of the second servo motor 8. The second servo motor 8 can drive the first gear 9 to rotate. A second gear 10 is fixedly connected to the end of the second screw 11 away from the extension rod 7. The second gear 10 meshes with the first gear 9. When the first gear 9 rotates, it drives the meshed second gear 10 to rotate. When the second gear 10 rotates, it drives the second screw 11 to rotate coaxially. Due to the threaded connection between the second screw 11 and the extension rod 7, the rotation of the second screw 11 can drive the extension rod 7 to extend or retract along the L-shaped support rod 6, thereby further improving the adjustable positioning range of the puncture needle 14.

[0027] Please see Figure 3 The second gear 10 is coaxially fixedly connected to a support shaft 17 on the side away from the second screw 11. When the second gear 10 rotates, it drives the support shaft 17 to rotate synchronously. The other end of the support shaft 17 is rotatably connected to the inner wall of the L-shaped support rod 6. The support shaft 17 limits the second gear 10 and the second screw 11 while ensuring the stability of the second screw 11 when it rotates.

[0028] Please see Figure 3 The end of the extension rod 7 away from the sleeve 13 is fixedly connected to the limiting plate 12. The limiting plate 12 limits the extension rod 7. The limiting plate 12 is engaged with the internal port of the L-shaped support rod 6. When the second screw 11 drives the extension rod 7 to move to the farthest distance, it is positioned by the limiting plate 12 to avoid the extension rod 7 from disengaging from the L-shaped support rod 6 as much as possible.

[0029] Working principle:

[0030] In use, the patient lies on the operating table 1. The first servo motor 3 and the second servo motor 8 are activated via the control panel 16. First, the first servo motor 3 is activated, which drives the first screw 4 to rotate forward or backward. Due to the threaded connection between the first screw 4 and the slider 5, the rotation of the first screw 4 drives the slider 5, the L-shaped support rod 6, and the puncture needle 14 to perform automatic lateral positioning adjustment. Then, the second servo motor 8 is activated, which drives the first gear 9 to rotate. The rotation of the first gear 9 drives the meshing second gear 10 to rotate. The rotation of the second gear 10 drives the second screw 11 to rotate coaxially. Due to the threaded connection between the second screw 11 and the extension rod 7, the rotation of the second screw 11 drives the extension rod 7 to extend or retract longitudinally along the L-shaped support rod 6, further improving the adjustable positioning range of the puncture needle 14. Finally, the infrared positioning lamp 15 is used to enhance the positioning and puncture effect.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the scope of protection of this utility model.
