[0034] The fixing mechanism 5 also includes four first fixing tubes 503, which are all fixedly mounted on the inner walls on both sides of the groove 501, and a first sliding rod 504 is slidably mounted on the first fixing tube 503. The corresponding two first sliding rods 504 are fixedly connected to the corresponding arc-shaped clamping blocks 502, and the arc-shaped clamping blocks 502 drive the first sliding rod 504 to slide on the first fixing tube 503.

[0035] The first sliding rod 504 is sleeved with a first spring 505 , one end of the first spring 505 is fixedly connected to the arc-shaped clamping block 502 , and the other end of the first spring 505 is fixedly connected to the first fixing tube 503 . The first spring 505 facilitates the resetting of the arc-shaped clamping block 502 .

[0036] The fixing mechanism 5 also includes two second fixing tubes 506, and the two second fixing tubes 506 are fixedly installed on the bottom inner wall of the groove 501. The second fixing tube 506 is located between the corresponding two first fixing tubes 503. A second sliding rod 507 is slidably installed on the second fixing tube 506, and the top of the two second sliding rods 507 is fixedly installed with the same annular block 508, and the bottom of the annular block 508 is fixedly installed with two wedge blocks 509. The arc-shaped clamping block 502 is provided with an inclined surface, and the wedge block 509 is adapted to the inclined surface. Through the cooperation between the wedge block 509 and the inclined surface, it is convenient to push the arc-shaped clamping block 502 to move, thereby realizing the fixation of the catheter 2.

[0037] A second spring 510 is sleeved on the second sliding rod 507, one end of the second spring 510 is fixedly connected to the annular block 508, and the other end of the second spring 510 is fixedly connected to the second fixed tube 506.

[0041] The above scheme is further introduced below in combination with the specific working method. See the following description for details:

[0042] Specifically, when the neurosurgical catheter device is used: Figure 3 As shown, the first spring 505 is in a stretched state, and the second spring 510 is in a compressed state;

[0043] When in use, first place the fixing block 1 at the position where the catheter 2 needs to be inserted, and then fix the whole on the patient through the two adhesive strips 4 on the elastic bandage 3, and then the doctor passes the catheter 2 through the fixing block 1 and finally inserts it into the patient's body;

[0044] After the catheter 2 is inserted into the designated position, the threaded block 511 is rotated, the threaded block 511 moves downward, the threaded block 511 drives the annular block 508 to move downward, and the annular block 508 drives the second sliding rod 507 to slide on the second fixed tube 506, at which time the second spring 510 is compressed;

[0045] At the same time, the annular block 508 drives the two wedge blocks 509 to move downward, and the wedge blocks 509 cooperate with the inclined surfaces on the arc-shaped clamping block 502, so that the two arc-shaped clamping blocks 502 move toward each other until the two arc-shaped clamping blocks 502 fix the catheter 2. At this time, the rotation of the threaded block 511 is stopped. The operation is simple, the fixation is firm, and the catheter 2 is prevented from falling off, ensuring normal treatment of the patient;

[0046] When the arc-shaped clamping block 502 moves, it will drive the first sliding rod 504 to slide on the first fixed tube 503, and at this time the first spring 505 is stretched;

[0047] When the catheter 2 needs to be pulled out, the threaded block 511 is rotated in the opposite direction. Under the elastic action of the first spring 505 and the second spring 510, the two arc-shaped clamping blocks 502 will move away from each other, so that the catheter 2 is no longer fixed. At this time, the catheter 2 can be pulled out.

[0048] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
