Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] One specific embodiment of this utility model is provided:

[0032] Reference Figure 1-3 A minimally invasive puncture device includes a base 1, a column 2 fixedly mounted on the upper middle part of the base 1, a groove 3 opened on one side of the column 2, a lead screw 4 rotatably mounted inside the groove 3, a motor 5 fixedly mounted on the lower end of the column 2, an installation rod 6 sleeved on the outer wall of the lead screw 4, a first electric push rod 7 fixedly mounted inside the installation rod 6, an installation box 8 fixedly connected to the output end of the first electric push rod 7, and the output end of the motor 5 fixedly connected to the lower end of the lead screw 4. The motor 5 drives the lead screw 4 to rotate, thereby driving the installation rod 6 to move up and down, and thus automatically adjusting the height of the puncture needle body 18 as needed.

[0033] Reference Figure 1 , 3-6. The mounting box 8 has first sliding grooves 9 on both sides inside. First sliding rods 10 are fixedly installed inside the two first sliding grooves 9. A sliding plate 11 is slidably installed between the two first sliding rods 10. The mounting box 8 has second sliding grooves 12 on both sides of the front end inside. Second sliding rods 13 are fixedly installed inside the two second sliding grooves 12. Clamping claws 14 are sleeved on the outer walls of the two second sliding rods 13 and extend out of the mounting box 8. Connecting rods 15 are rotatably installed on both sides of the upper end of the sliding plate 11. A connecting tube 17 is clamped between the two clamping claws 14. A puncture needle body 18 is fixedly connected to the lower end of the connecting tube 17. The ends of the two connecting rods 15 away from the sliding plate 11 are rotatably installed on the upper ends of the corresponding clamping claws 14. Soft pads 16 are fixedly installed inside the two clamping claws 14. The rotation of the connecting rods 15 on both sides causes the clamping claws 14 to move relative to each other, thereby clamping and fixing the connecting tube 17. The soft pads 16 are used to clamp and fix the connecting tube 17. To protect the surface of the connecting pipe 17 from damage caused by the gripper 14, a fixed plate 19 is fixedly installed inside the mounting box 8 on the side away from the slide plate 11. A second electric push rod 20 is fixedly installed inside the fixed plate 19. The output end of the second electric push rod 20 is fixedly connected to one side of the slide plate 11.

The four corners of the lower end of the base 1 are fixedly equipped with hydraulic push rods 22 near the moving wheels 21. The output ends of the four hydraulic push rods 22 are fixedly connected to the support plate 23. The hydraulic push rods 22 drive the support plate 23 to move, causing the moving wheels 21 to leave the ground, which further improves the stability of the device during use. A control panel 24 is fixedly installed at the front end of the column 2 to facilitate the control of the device's operation.

[0034] Working principle: When using this minimally invasive puncture device, the motor 5 drives the lead screw 4 to rotate, thereby moving the mounting rod 6 up and down. With the cooperation of the first electric push rod 7, medical personnel can automatically adjust the height and position of the puncture needle body 18 as needed, making it more convenient to position the puncture needle body 18 during surgery. The second electric push rod 20 pushes the slide plate 11 to move, and under the action of the connecting rod 15, it drives the clamping claws 14 on both sides to move relative to each other, thereby clamping the connecting tube 17 and fixing the puncture needle body 18. This facilitates disassembly, assembly, or replacement of puncture needle bodies 18 of different specifications. At the same time, the hydraulic push rod 22 further improves the stability of the device during use.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
