[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please refer to Figures 1-7. The present invention provides the following technical solution: a neurosurgical microsurgical aspirator with anti-aspiration function, comprising an aspirator tube body 1, a negative pressure regulator 4 at the upper end of the aspirator tube body 1, a connecting tube 2 at the upper end of the negative pressure regulator 4, an aspirator head body 6 at the lower end of the aspirator tube body 1, a storage bottle fixing mechanism 3 fixedly connected to the upper end of the connecting tube 2, and the aspirator tube body 1 and the aspirator head body 6 fixedly connected by an aspirator tube connecting fixing mechanism 5. A smoke absorption mechanism 7 is installed on the surface of the aspirator head body 6.

[0033] Furthermore, the smoke absorption mechanism 7 of the present invention includes an extractor head hole structure 71, a smoke absorption hole structure 72, a connecting post 73, a connecting cylinder 74, a hollow ring 75, an absorption cylinder 76, a suction fan 77, and a dustproof net 78. A suction fan 77 is fixedly connected to one side of the extractor head body 6, a dustproof net 78 is provided on one side of the suction fan 77, and an absorption cylinder 76 is fixedly connected to the other side of the suction fan 77. A hollow ring 75 is fixedly connected to the other end of the absorption cylinder 76. Multiple sets of connecting cylinders 74 are installed on the side of the hollow ring 75, and a connecting post 73 is fixedly connected to the other end of the connecting cylinder 74. The smoke absorption hole structure 72 is opened inside the connecting post 73, and the extractor head body 6 has an extractor head hole structure 71 inside.

[0034] By adopting the above technical solution, when the device is in use, the suction fan 77 is turned on, and the dustproof net 78 can prevent dust from entering the interior of the suction fan 77. The suction force generated by the suction fan 77 can allow the suction force to enter through the connecting column 73, connecting cylinder 74, hollow ring 75 and absorption cylinder 76, thereby absorbing the smoke through the smoke absorption hole structure 72 and preventing the smoke from affecting the normal use of the device.

[0035] Furthermore, the suction head hole structure 71 of the present invention includes a large hole 711 and a funnel hole 712. The large hole 711 is provided on one side of the interior of the suction head body 6, and the funnel hole 712 is provided on the other side of the interior of the suction head body 6.

[0036] By adopting the above technical solution, the suction head hole structure 71, composed of a funnel hole 712 and a large hole 711, can facilitate the absorption of blood and bone fragments. At the same time, the diameter of the funnel hole 712 at the end of the suction head body 6 is smaller than the inner diameter of the large hole 711 at the center of the suction head body 6, thereby effectively preventing accidental aspiration and improving the suction effect of the suction device.

[0037] Furthermore, the smoke absorption hole structure 72 of the present invention includes a second funnel hole 721 and a small hole 722. The second funnel hole 721 is provided at the connection between the inner side of the connecting column 73 and the connecting cylinder 74, and the small hole 722 is provided at the other end of the second funnel hole 721 inside the connecting column 73.

[0038] By adopting the above technical solution, and by setting the smoke absorption hole structure 72 into a channel composed of small holes 722 and funnel holes 721, the structure can be prevented from sucking in blood and bone fragments.

[0039] In this embodiment, when using the device, the suction fan 77 is turned on. The dustproof net 78 can prevent dust from entering the interior of the suction fan 77. The suction force generated by the suction fan 77 allows the suction to enter through the connecting column 73, connecting cylinder 74, hollow ring 75, and absorption cylinder 76, thereby absorbing the smoke through the smoke absorption hole structure 72 and preventing the smoke from affecting the normal use of the device. The suction head hole structure 71, composed of the funnel hole 712 and the large hole 711, facilitates the absorption of blood and bone fragments. At the same time, the diameter of the funnel hole 712 at the end of the suction head body 6 is smaller than the inner diameter of the large hole 711 at the center of the suction head body 6, thereby effectively preventing accidental aspiration and improving the suction effect of the suction device. By setting the smoke absorption hole structure 72 as a channel composed of the small hole 722 and the funnel hole 721, the structure can be prevented from sucking in blood and bone fragments.

[0042] By adopting the above technical solution, when connecting and fixing the suction tube body 1 and the suction head body 6, the insert block 55 on the side of the ear plate 1 53 is inserted into the slot 59 inside the ear plate 2 58, and then, with the cooperation of the fixing component 56 and the locking hole 54, the connection and fixing of the suction tube body 1 and the suction head body 6 can be achieved.

[0043] Furthermore, the suction tube connection and fixing mechanism 5 of the present invention also includes a sealing ring 51 and a sealing groove 57. The sealing ring 51 is fixed on one side of the suction tube body 1 near the plug 52, and a sealing groove 57 corresponding to the sealing ring 51 is provided on one side of the suction head body 6.

[0044] By adopting the above technical solution, when the suction tube body 1 and the suction head body 6 are connected and fixed, the sealing ring 51 is installed inside the sealing groove 57, thereby improving the connection sealing between the suction tube body 1 and the suction head body 6.

[0045] Furthermore, the fixing component 56 includes a pull rod 561, a pull ring 562, a spring 563, a limiting plate 564, and a locking rod 565. The limiting plate 564 is provided inside the side of the slot 59. A circular groove corresponding to the limiting plate 564 is formed inside the ear plate 58. A locking rod 565 is provided at one end of the limiting plate 564, and a pull rod 561 is provided at the other end. A pull ring 562 is provided at the other end of the pull rod 561. The spring 563 is sleeved inside the circular groove on the surface of the pull rod 561.

[0046] By adopting the above technical solution, when connecting and fixing the suction tube body 1 and the suction head body 6, pulling the pull ring 562 will pull the pull rod 561, which in turn will pull the limiting plate 564 and the locking rod 565, and cause the spring 1 563 to compress. Then, the insert block 55 on the side of the ear plate 1 53 will be inserted into the slot 59 inside the ear plate 2 58. With the cooperation of the fixing component 56 and the locking hole 54, the connection and fixing of the suction tube body 1 and the suction head body 6 can be achieved. When the pull ring 562 is released, the spring 1 563 will rebound, thereby causing the locking rod 565 to be inserted into the locking hole 54, so as to achieve the connection and fixing of the suction tube body 1 and the suction head body 6.

[0047] Furthermore, an arc-shaped structure 566 is provided on one side of the lever 565.

[0048] By adopting the above technical solution, the structure can facilitate the insertion of the locking rod 565 into the locking hole 54.

[0049] In this embodiment, when connecting and fixing the suction tube body 1 and the suction head body 6, pull the pull ring 562. The pull ring 562 pulls the pull rod 561, the pull rod 561 pulls the limiting plate 564 and the locking rod 565, and drives the spring 1 563 to compress. Then, insert the insert block 55 on the side of the ear plate 1 53 into the slot 59 inside the ear plate 2 58. With the cooperation of the fixing component 56 and the locking hole 54, the connection and fixing of the suction tube body 1 and the suction head body 6 can be achieved. When the pull ring 562 is released, the spring 1 563 rebounds, thereby driving the locking rod 565 to be inserted into the inside of the locking hole 54, so as to achieve the connection and fixing of the suction tube body 1 and the suction head body 6. When the suction tube body 1 and the suction head body 6 are connected and fixed, the sealing ring 51 is installed inside the sealing groove 57, thereby improving the connection sealing performance of the suction tube body 1 and the suction head body 6.

[0050] Example 3

[0051] The difference between this embodiment and the above embodiments is that the bottle fixing mechanism 3 includes a connecting seat 31, a central rod 32, a spring 33, an L-shaped mounting groove 34, a fixing rod 35, a connecting hole 36, a limiting component 37, a square groove 38, a sliding plate 39, a fixing hole 310, a square connecting frame 311, and a bottle body 312. The other end of the connecting pipe 2 is fixedly connected to the connecting seat 31. The connecting seat 31 has a connecting hole 36 corresponding to the connecting pipe 2 at its center. The connecting seat 31 has a square groove 38 at its center on its side. A square connecting frame 311 is installed, with a fixing hole 310 on its side. A bottle body 312 is provided at the other end of the square connecting frame 311. An L-shaped mounting groove 34 is provided on the side of the connecting seat 31, and a sliding plate 39 is slidably connected inside the L-shaped mounting groove 34. A fixing rod 35 is provided at the lower end of the side of the sliding plate 39. A central rod 32 is provided through the upper end of the sliding plate 39. A spring 33 is sleeved on the surface of the central rod 32 on the side of the sliding plate 39. A limit component 37 is provided at the lower end of the sliding plate 39 inside the connecting seat 31.

[0052] By adopting the above technical solution, when fixing the storage bottle body 312, first slide the sliding plate 39. The sliding plate 39 slides on the surface of the central rod 32 and drives the second spring 33 to compress. At the same time, the fixing rod 35 is embedded in the L-shaped mounting groove 34. Then, the square connecting frame 311 on the side of the storage bottle body 312 is inserted into the square groove 38. At this time, the sliding plate 39 is released, the second spring 33 rebounds, thereby driving the fixing rod 35 to be inserted into the fixing hole 310, so as to fix the storage bottle body 312.

[0053] Furthermore, the limiting component 37 of the present invention includes a limiting block 371 and a limiting groove 372. The lower end of the sliding plate 39 is provided with a limiting block 371, and the lower end of the L-shaped mounting groove 34 is provided with a limiting groove 372 corresponding to the limiting block 371.

[0054] By adopting the above technical solution, when the skateboard 39 slides, it will cause the limiting block 371 to slide inside the limiting groove 372, thereby improving the stability of the skateboard 39 during the sliding process.

[0055] In this embodiment, when fixing the storage bottle body 312, the sliding plate 39 is first slid. The sliding plate 39 slides on the surface of the central rod 32 and compresses the second spring 33, causing the fixing rod 35 to be embedded in the L-shaped mounting groove 34. Then, the square connecting frame 311 on the side of the storage bottle body 312 is inserted into the square groove 38. At this time, the sliding plate 39 is released, the second spring 33 rebounds, thereby causing the fixing rod 35 to be inserted into the fixing hole 310, so as to fix the storage bottle body 312. When the sliding plate 39 slides, it will cause the limiting block 371 to slide inside the limiting groove 372, thereby improving the stability of the sliding process of the sliding plate 39.

[0056] The structure and working principle of the negative pressure regulator 4 in this invention have been disclosed in a neurosurgical anti-aspiration microscopic aspirator disclosed in Chinese patent application number 202220738449.8. Its working principle is to control the suction force of the aspirator.

[0057] Working principle and usage process of the present invention: When using the device, turn on the suction fan 77. The dustproof net 78 can prevent dust from entering the interior of the suction fan 77. The suction force generated by the suction fan 77 allows the suction to enter through the connecting column 73, connecting cylinder 74, hollow ring 75, and absorption cylinder 76, thereby absorbing the smoke through the smoke absorption hole structure 72, preventing the smoke from affecting the normal use of the device. The suction head hole structure 71, composed of the funnel hole 712 and the large hole 711, facilitates the absorption of blood and bone fragments. At the same time, the end of the suction head body 6... The diameter of the funnel hole 712 is smaller than the inner diameter of the large hole 711 at the center of the suction head body 6, thus effectively preventing accidental aspiration and improving the suction effect of the suction device. By setting the smoke absorption hole structure 72 into a channel composed of the small hole 722 and the funnel hole 721, the structure can be prevented from sucking in blood and bone fragments. When connecting and fixing the suction tube body 1 to the suction head body 6, pull the pull ring 562, which pulls the pull rod 561. The pull rod 561 pulls the limiting plate 564 and the locking rod 565, and drives the spring 563 to compress, and then the insert block 55 on the side of the ear plate 53 is pushed. Insert the suction tube body 1 into the slot 59 inside the ear plate 58, and with the fixing component 56 and the locking hole 54, the suction tube body 1 and the suction head body 6 can be connected and fixed. Loosen the pull ring 562, and the spring 563 returns, thereby driving the locking rod 565 to insert into the locking hole 54, thus connecting and fixing the suction tube body 1 and the suction head body 6. When the suction tube body 1 and the suction head body 6 are connected and fixed, the sealing ring 51 is installed inside the sealing groove 57, thereby improving the sealing performance of the connection between the suction tube body 1 and the suction head body 6. (The last sentence appears to be incomplete and possibly refers to a different topic.) 2. When fixing, first slide the slide plate 39. The slide plate 39 slides on the surface of the central rod 32 and drives the second spring 33 to compress. At the same time, the fixing rod 35 is inserted into the L-shaped mounting groove 34. Then, insert the square connecting frame 311 on the side of the storage bottle body 312 into the square groove 38. At this time, release the slide plate 39, and the second spring 33 rebounds, thereby driving the fixing rod 35 to be inserted into the fixing hole 310 to fix the storage bottle body 312. When the slide plate 39 slides, it will drive the limiting block 371 to slide inside the limiting groove 372, thereby improving the stability of the slide plate 39 during the sliding process.
