On the other hand, through the cooperation between the drainage cavity 7, the drain pipe 21 and the opening 12, it is convenient to adsorb the liquid after flushing and discharge it into the external drainage device.

[0031] AsFigure 3 , Figure 4 and Figure 7 As shown in Figure 7 , it should be noted that a baffle 22 is provided inside the inner cylinder 2, which is convenient for partitioning the liquid in the converging cylinder 1 and the inner cylinder 2, thereby avoiding damage to the first drive motor 552 and the second drive motor 42.

[0032] As Figure 4 , Figure 6 and Figure 7 As shown in Figure 7 , preferably, chutes are respectively provided on the opposite sides of the inner wall of the inner cylinder 2, and limiting rods are respectively provided on the opposite sides of the mounting shell 41 and are respectively located in the two chutes, which is convenient for limiting the limiting rods through the chutes, thereby increasing the stability of the mounting shell 41 and the second drive motor 42 during movement.

[0033] As Figure 2 and Figure 7 As shown in Figure 7 , as a possible situation, in another embodiment of the present invention, a controller is provided on the plug and is electrically connected to the second drive motor 42 and is located outside the outer cylinder 3, which is convenient for operating the start and stop of the second drive motor 42.

[0034] As Figure 6 and Figure 7 As shown in Figure 7 , in one embodiment of the present invention, the crushing device 4 includes: a mounting shell 41, a second drive motor 42, a guide rod 43, a fixed shell 44, a main blade 45, a sliding rod 46, a secondary blade 47 and a second spring 48.

[0035] Among them, the mounting shell 41 is arranged on the slider 554, the second drive motor 42 is arranged in the mounting shell 41, and the driving end of the second drive motor 42 passes through the baffle 22 and extends.

A plurality of second springs 48 are respectively connected to the sliding rod 46 and the fixed shell 44 and are respectively located in each fixed shell 44.

[0036] As Figure 6 and Figure 7 As shown in Figure 7 , it should be noted that an auxiliary crushing cone 431 is provided at the end of the guide rod 43, which is convenient for initially crushing the blood sample tissue lesions, thereby reducing the wear rate and other situations of the plurality of main blades 45 and the plurality of secondary blades 47 during operation.

[0037] As Figure 3 , Figure 4 and Figure 7As shown, preferably, a plurality of stabilizing devices are provided inside the inner cylinder 2 to prevent the guide rod 43 from shaking when rotating.

[0038] like Figure 3 , Figure 4 and Figure 7 As shown, the above-mentioned stabilizing device includes: a mounting ring, a stabilizing ring and a connecting rod.

[0039] The mounting ring is arranged on the inner wall of the inner tube 2, and the stabilizing ring is sleeved on the guide rod 43 and connected to the mounting ring through a plurality of connecting rods.

[0040] like Figures 3 to 5 As shown, the self-driving device 5 includes: a limit slide bar 51 , a start switch 52 , a reset switch 53 , a first spring 54 and a moving structure 55 .

[0041] Among them, the limiting slide bar 51 slides in the installation groove 11, the starting switch 52 and the reset switch 53 are respectively arranged in the installation groove 11 and are located on both sides of the limiting slide bar 51, and the starting switch 52 and the reset switch 53 are respectively electrically connected to the driving end of the moving structure 55, and the starting switch 52 and the reset switch 53 are respectively provided with a first spring 54, and one end of the two first springs 54 is respectively connected to the two ends of the limiting slide bar 51, the moving structure 55 is arranged in the inner cylinder 2, and the crushing device 4 is arranged on the moving end of the moving structure 55.

[0042] like Figure 3 , Figure 4 and Figure 7 As shown, it should be noted that a limiting plate 511 is provided on the limiting slide bar 51 and fits with the inner wall of the gathering tube 1, and multiple slide rods 46 fit with the inner wall of the limiting plate 511 respectively, so that the multiple slide rods 46 can rotate along the limiting plate 511.

[0043] like Figure 4 As shown, it should be noted that the materials of the limiting slide bar 51 and the limiting plate 511 are respectively rubber, so that they can be bent.

[0044] like Figure 4 and Figure 5 As shown, it should be noted that the cross-sections of the limiting slide bar 51 and the mounting groove 11 are respectively T-shaped, so that the limiting slide bar 51 can be limited by the mounting groove 11 to prevent it from being separated from the mounting groove 11.

[0045] like Figure 4 and Figure 5 As shown, it should be noted that the start switch 52 and the reset switch 53 are respectively located at the gathering part and the diffusion part of the gathering tube 1.

[0046] like Figures 4 to 7As shown, for the sake of clearly explaining the previous embodiment, in an embodiment of the present invention, the moving structure 55 includes: a mounting base 551, a first driving motor 552, a lead screw 553, and a slider 554.

[0047] Among them, the mounting base 551 is arranged on the baffle 22 close to the plugging side. The first driving motor 552 is arranged on the mounting base 551 through a mounting frame and is electrically connected to the start switch 52 and the reset switch 53. The lead screw 553 is axially connected to the mounting base 551, and the driving end of the first driving motor 552 passes through the mounting base 551 and is connected to the lead screw 553. The slider 554 is arranged on the lead screw 553.

[0048] Specifically, when the present invention needs to be used, first, the liquid injection end of an external liquid injection device and the drainage end of a drainage device are respectively installed on the liquid injection pipe 32 and the drainage pipe 21, and the liquid injection device and the drainage device are started. At this time, the liquid injection device injects the cleaning liquid into the cleaning liquid chamber 6 through the liquid injection pipe 32 and discharges it from the liquid outlet hole 31 to wash the affected area of the patient. At the same time, the external drainage device makes the drainage chamber 7 in a negative pressure state through the drainage pipe 21. Then, the liquid after flushing the affected area of the patient is sucked into the drainage chamber 7 through the opening 12 at the lower end of the gathering cylinder 1 and discharged to the external drainage device through the drainage pipe 21.

[0049] It should be noted that when in use, the second driving motor 42 is turned on. Through the operation of the second driving motor 42, the guide rod 43, multiple fixed shells 44, multiple main blades 45, multiple sliding rods 46, multiple secondary blades 47, and the auxiliary crushing cone 431 are driven to rotate in sequence. And at this time, the liquid that has flushed the affected area of the patient will contain blood sample tissue lesions. Small pieces of blood sample tissue lesions will directly enter the drainage chamber 7 and be sucked away. After large pieces of blood sample tissue lesions enter the drainage chamber 7, they will be blocked by the limiting plate 511. At this time, due to the suction force, the blood sample tissue lesions are driven to move upward for a certain distance, and then the limiting plate 511 and the limiting slide bar 51 are driven to move in sequence. At the same time, one of the first springs 54 is compressed and the other first spring 54 is stretched, and it contacts the start switch 52 through the compressed first spring 54. Then, the first driving motor 552 is turned on through the start switch 52, so that the first driving motor 552 drives the second driving motor 42 to move towards the blood sample tissue lesions, and then drives the crushing device 4 to move, so as to crush the blood sample tissue lesions. When the blood sample tissue lesions are crushed, due to the suction force, the blood sample tissue lesions are driven to move upward. At this time, the force on the limiting plate 511 becomes smaller, and through the self-elastic return of the first spring 54, the limiting slide bar 51 is driven to reset and contacts the reset switch 53. At this time, the first driving motor 552 drives the crushing device 4 to move in the reverse direction, so as to reset it.

[0050] It should be noted that during the reset process of the crushing device 4, it can drive the crushed blood sample tissue lesions to move upward assistively.

[0051] In summary, for a flushing surgical device for neurosurgery according to an embodiment of the present invention, through the cooperation between the self-driving device 5 and the crushing device 4, on the one hand, it is convenient to drive the limiting plate 511 to move through the large blood sample tissue lesions, and then automatically start and stop the first driving motor 552, thereby driving the crushing device 4 to reciprocate, and then performing crushing and auxiliary upward movement on the blood sample tissue lesions. On the other hand, it avoids situations such as blockage.
