Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The embodiment of the utility model is described below in conjunction with the drawings.

[0022] like Figure 1-3As shown, the medical catheter fixed-length cutting device comprises a bottom plate 1, on which a catheter groove 9 for placing the catheter to be cut is provided, and at one end of the bottom plate 1 two fixing brackets 4 are provided, the two fixing brackets 4 are symmetrically arranged about the bottom plate 1, an upper blade fixing bracket 7 and a lower blade fixing bracket 12 are provided between the two fixing brackets 4, the upper blade fixing bracket 7 is arranged above the lower blade fixing bracket 12, the upper blade fixing bracket 7 is slidably connected to the two fixing brackets 4, an upper blade 2 is provided on the upper blade fixing bracket 7, and a lower blade 13 is provided on the lower blade fixing bracket 12, the blade edge of the upper blade 2 faces the lower blade 13, and the blade edge of the lower blade 13 faces the upper blade 2;

[0023] The bottom plate 1 is used to support the catheter to be cut, and the catheter groove 9 cooperates with the catheter to be cut to position the catheter to be cut, which can ensure that the catheter to be cut will not deviate left or right, and the fixed length is more accurate. The two fixed brackets 4 are used to support the upper blade fixing frame 7 and the lower blade fixing frame 12, wherein the upper blade fixing frame 7 can move up and down to facilitate cutting of the catheter;

[0024] The upper blade fixing frame 7 is provided with an upper blade mounting hole 3 for fixing the upper blade 2. The upper blade mounting hole 3 is used to fix the upper blade 2. The corresponding upper blade 2 is also provided with a through hole for fixing and mounting by bolts. Two upper blade mounting holes 3 can be provided to facilitate more stable installation.

[0025] The lower blade fixing frame 12 is provided with a lower blade mounting hole 11 for fixing the lower blade 13. The lower blade mounting hole 11 is used to fix and install the lower blade 13. The corresponding lower blade 13 is also provided with a through hole for fixing and installing by bolts. Two lower blade mounting holes 11 can be provided to facilitate more stable installation.

[0026] A lower semicircular notch 10 is provided on the lower blade 13, and the lower semicircular notch 10 is aligned with the conduit groove 9;
