[0018] S1. Align the alignment rod with the puncture position, attach the device to the position to be punctured, then rotate the drive gear. The drive gear drives the follower gear to rotate, the follower gear drives the threaded rod to rotate, the threaded rod drives the positioning block to slide, and the positioning block drives the puncture needle to be pushed out.

[0019] S2. As the puncture needle extends, the active rack on the positioning block drives the rotating gear to rotate, the rotating gear drives the follower rack to slide, the follower rack drives the transmission block to slide, the transmission block drives the connecting block to slide, the connecting block drives the connecting rod to slide, the connecting rod drives the cleaning block to slide, and at the same time, the puncture needle drives the top block to slide, the top block presses the nozzle, the nozzle absorbs disinfectant from the disinfection box through the suction tube and sprays it out from the nozzle, disinfecting the puncture needle while also wiping and cleaning it.

[0022] S5. After using the equipment, press the four buttons on the top of the cover simultaneously. The buttons will cause the support rod to slide down, which in turn causes the base block to slide down. The base block will then cause the sliding rods on both sides to slide inward, which in turn causes the locking mechanism to slide inward, thereby separating the cover from the base for maintenance of the base's interior.

[0023] The working principle and beneficial effects of this invention are as follows:

[0024] 1. The present invention, through the setting of follower gear, threaded rod and other structures, when the equipment is used, the rotation of the drive gear drives the driven shaft to rotate, drives the threaded rod to rotate, drives the sliding block to slide, drives the puncture needle to slide, drives the transmission block to slide, drives the cleaning block to slide. When the puncture needle is extended, the cleaning block slides at the same time to disinfect and clean the puncture needle, making it more convenient to use.

[0025] 2. The present invention, through the design of the disinfection box and the box opening, allows the puncture needle to extend outward while the top block slides during use, driving the nozzle downward. This causes the disinfectant in the disinfection box to be drawn in through the suction tube and sprayed out through the nozzle to disinfect the puncture needle. At the same time, when the disinfectant is almost used up, the lid can be removed at the box opening to add more disinfectant, making the disinfection of the equipment more convenient.

[0026] 3. By incorporating compression springs, return springs, and other structural features, this invention allows for easy separation of the top cover and base when the equipment needs maintenance and cleaning after use. This is achieved by pressing a button, which slides the base block and the locking mechanism, allowing for simultaneous pressing of all four buttons. This makes maintenance of the equipment more convenient. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] As shown in Figures 1-7, this embodiment proposes a minimally invasive interventional tumor puncture locator, including a base 2 and a top cover 3. A transmission assembly is disposed inside the base 2, including a drive shaft 206. A drive gear 205 is fixedly connected to the outer circumferential surface of the drive shaft 206. A driven shaft 201 is rotatably mounted inside the base 2. A follower gear 203 is fixedly connected to the outer circumferential surface of the driven shaft 201. A threaded rod 204 is threadedly connected inside the driven shaft 201. A sliding block 207 is fixedly connected to the bottom of the threaded rod 204. A drive rack 208 is fixedly connected to one side of the sliding block 207. A puncture needle 219 is fixedly connected to the bottom of the sliding block 207. A rotating shaft 222 is rotatably mounted inside the base 2. A rotating gear 221 is fixedly connected to the outer circumferential surface of the rotating shaft 222. The rotating gear 221 meshes with the drive rack 208. A transmission block 210 is slidably assembled inside the base 2. A follower rack 211 is fixedly connected to one side of the transmission block 210. The follower rack 211 meshes with the rotating gear 221. A connecting block 220 is fixedly connected to the bottom of the transmission block 210. A connecting rod 216 is fixedly connected to the bottom of the connecting block 220. Two symmetrically arranged connecting rods 216 are fixedly connected to the bottom of the connecting rods 216. A cleaning block 212 is fixedly connected to one end of the two connecting rods 216. An alignment rod 202 is fixedly connected to the bottom of the base 2. A positioning block 209 is fixedly connected inside the base 2. Through the setting of structures such as the follower gear 203 and the threaded rod 204, when the equipment is used, rotating the drive gear 205 drives the driven shaft 201 to rotate, drives the threaded rod 204 to rotate, drives the sliding block 207 to slide, drives the puncture needle 219 to slide, drives the transmission block 210 to slide, and drives the cleaning block 212 to slide. When the puncture needle 219 is extended, it drives the cleaning block 212 to slide. Simultaneously sliding the needle 219 allows for disinfection and cleaning, making it more convenient to use.

[0040] As shown in Figures 1 to 7, the base 2 has a rotating groove inside, the driven shaft 201 is rotatably installed inside the rotating groove, and the drive shaft 206 is rotatably installed inside the rotating groove.

[0041] As shown in Figures 1 to 7, the driven shaft 201 has a threaded groove inside, the threaded rod 204 is threadedly connected inside the threaded groove, the base 2 has a square groove inside, and the sliding block 207 is slidably connected inside the square groove.

[0042] As shown in Figures 1 to 5, the sliding block 207 has a positioning groove inside, the positioning block 209 is slidably connected inside the positioning groove, the alignment rod 202 has a circular groove inside, and the cleaning block 212 is slidably connected inside the circular groove.

[0043] As shown in Figures 1 to 7, the base 2 has a circular hole inside, and the puncture needle 219 is slidably connected inside the circular hole. The alignment rod 202 has a slot inside, and the puncture needle 219 is slidably connected inside the slot.

[0044] In this embodiment, when the device is in use, rotating the drive gear 205 causes the drive shaft 206 to rotate, which in turn causes the follower gear 203 to rotate. The follower gear 203 then causes the driven shaft 201 to rotate, which in turn causes the threaded rod 204 to rotate. The threaded rod 204 then causes the sliding block 207 to slide, which in turn causes the puncture needle 219 to slide. The puncture needle 219 then causes the top block 213 to slide. Simultaneously, the sliding block 207 causes the drive rack 208 to slide, which in turn causes the rotating gear 221 to rotate. The rotating gear 221 then causes the follower rack 211 to slide, which in turn causes the transmission block 210 to slide. The transmission block 210 then causes the two connecting blocks 220 to slide, which in turn causes the connecting rod 216 to slide. The connecting rod 216 then causes the cleaning block 212 to slide. After the device completes the puncture, the drive gear 205 is rotated in the opposite direction. By reversing the above steps, the puncture needle 219 can be stored in the base 2. The puncture needle 219 can be wiped during use.

[0045] Example 2

[0046] As shown in Figures 1 to 7, based on the same concept as Embodiment 1 above, this embodiment also proposes that the base 2 is internally equipped with a disinfection box 218, and a straw 215 is fixedly connected inside the disinfection box 218. A nozzle 214 is installed at one end of the straw 215, and a box opening 217 is provided on one side of the disinfection box 218. A top block 213 is fixedly fitted on the outer peripheral surface of the puncture needle 219. Through the arrangement of the disinfection box 218, the box opening 217, etc., when using the equipment, the puncture needle 219 extends outward while the top block 213 slides, driving the nozzle 214 to press down, so that the disinfectant water in the disinfection box 218 is drawn in from the straw 215 and sprayed out from the nozzle 214 to disinfect the puncture needle 219. At the same time, when the disinfectant is almost used up, the lid can be removed at the box opening 217 to add disinfectant water to the disinfection box 218, making the equipment disinfection more convenient.

[0047] As shown in Figures 1 to 6, the inside of the disinfection box 218 has a through hole, the box opening 217 passes through the inside of the through hole, and the inside of the disinfection box 218 has a recessed hole, through which the straw 215 passes.

[0048] In this embodiment, when the device is in use, the puncture needle 219 drives the top block 213 to slide, the top block 213 presses down the nozzle 214, the nozzle 214 draws in disinfectant from the suction tube 215 and sprays it onto the surface of the puncture needle 219. At the same time, when the puncture needle 219 extends, it drives the cleaning block 212 to retract inward, cleaning the disinfectant from the surface of the puncture needle 219. Meanwhile, a box opening 217 is installed on one side of the disinfection box 218, and disinfectant can be poured in from the box opening 217 after the disinfectant is used up, making the device more hygienic and safe to use.

[0049] Example 3

[0050] As shown in Figures 1 to 5, based on the same concept as Embodiments 1 and 2 above, this embodiment also proposes that the bottom of the upper cover 3 is fixedly connected with four arrayed and equidistantly distributed fixing blocks 4. The inside of the fixing blocks 4 is slidably fitted with support rods 5. The top of the support rods 5 is fixedly connected with buttons 6. The bottom of the support rods 5 is fixedly connected with a base block 7. Both sides of the base block 7 are slidably fitted with slide rods 9. One side of each slide rod 9 is fixedly connected with a locking lock 1. Through the setting of structures such as compression springs 8 and return springs 10, when the equipment needs to be cleaned after use, buttons 6 can be pressed to drive the base block 7 to slide, which in turn drives the locking lock 1 to slide. Thus, pressing all four buttons 6 at the same time can separate the upper cover 3 and the base 2, making it more convenient to perform maintenance on the equipment.

[0051] As shown in Figures 1 to 5, the fixed block 4 has a slider groove inside, the bottom block 7 is slidably connected inside the slider groove, and a compression spring 8 is connected between the bottom block 7 and the inner wall of the slider groove. The fixed block 4 has a slot inside, the lock 1 is slidably connected inside the slot, and a return spring 10 is sleeved on the outside of the slide rod 9. The return spring 10 is also connected between the lock 1 and the inner wall of the slot.

[0052] In this embodiment, after the device is used up, all four buttons 6 are pressed simultaneously. Buttons 6 cause the support rod 5 to slide, the support rod 5 causes the base block 7 to slide, the base block 7 causes the sliding rods 9 on both sides to retract inward, and the sliding rods 9 cause the locking 1 to slide inward. At this time, the top cover 3 and the base 2 can be separated to maintain the device and ensure smoother use next time. The disassembly of the installation structure makes the device easier to maintain.

[0053] A method for using a minimally invasive interventional tumor puncture locator, employing the aforementioned minimally invasive interventional tumor puncture locator, includes the following steps: S1, aligning the alignment rod 202 with the puncture position, attaching the device to the required puncture position, then rotating the drive gear 205, which drives the follower gear 203 to rotate, the follower gear 203 drives the threaded rod 204 to rotate, the threaded rod 204 drives the positioning block 209 to slide, and the positioning block 209 drives the puncture needle 219 to extend; S2, simultaneously with the extension of the puncture needle 219, the drive rack 208 on the positioning block 209 drives the rotating gear 221 to rotate, the rotating gear 221 drives the follower rack 211 to slide, the follower rack 211 drives the transmission block 210 to slide, the transmission block 210 drives the connecting block 220 to slide, the connecting block 220 drives the connecting rod 216 to slide, and the connecting rod 216 drives the cleaning block 212. S3. S1. After the puncture procedure, the drive gear 205 is rotated in the opposite direction. The drive gear 205 rotates in the opposite direction. The follower gear 203 rotates in the opposite direction. The follower gear 203 rotates in the opposite direction. The threaded rod 204 rotates in the opposite direction. The threaded rod 204 rotates in the opposite direction. The positioning block 209 slides in the opposite direction. The positioning block 209 retracts the puncture needle 219. S4. S1. As the puncture needle 219 retracts, the drive rack 208 on the positioning block 209 rotates in the opposite direction. The drive gear 213 rotates in the opposite direction. The drive gear 214 rotates in the opposite direction. The follower rack 211 slides in the opposite direction. The follower rack 211 slides in the opposite direction. The transmission block 210 is driven to slide in the reverse direction, which in turn drives the connecting block 220 to slide in the reverse direction. The connecting block 220 drives the connecting rod 216 to slide in the reverse direction, which in turn drives the cleaning block 212 to slide in the reverse direction. At the same time, the puncture needle 219 drives the top block 213 to slide in the reverse direction. The top block 213 presses the nozzle 214, which absorbs disinfectant from the disinfection box 218 through the suction tube 215 and sprays it out. While the cleaning block 212 wipes the dirt on the puncture needle 219, the top block 213 slides in the reverse direction, causing the nozzle 214 to spray disinfectant to disinfect the puncture needle 219. S5. After the equipment is used, press the four buttons 6 on the top of the cover 3 at the same time. The buttons 6 drive the support rod 5 to slide downward, which in turn drives the bottom block 7 to slide downward. The bottom block 7 drives the sliding rods 9 on both sides to slide inward, and the sliding rods 9 drive the locking 1. Slide inwards,This allows the top cover 3 and the base 2 to be separated, enabling maintenance of the interior of the base 2.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
