The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] First embodiment:

[0024] See also Figure 1 to Figure 3 ,in Figure 1 It is a three-dimensional stereogram of the first embodiment of the utility model. Figure 2 This is a front view of the first embodiment of the utility model. Figure 3 The utility model Figure 2 Section view along line AA.

[0025] The utility model provides a catheter fixing device, including a mounting block 101, a rectangular block 102 and a fixing mechanism, wherein the fixing mechanism includes a screw 119, a first L-shaped block 110, a second L-shaped block 111 and two positioning rods 116. The above-mentioned scheme solves the technical problem that the U-shaped block is fixed to the edge of the operating table by bolts, so that the contact area between the edge of the operating table and the U-shaped block is small, and thus it is easy to loosen.

[0026] According to the present specific embodiment, the mounting block 101 is provided with an adjustment mechanism 103, one end of the mounting block 101 is provided with a fixed block 104, the fixed block 104 is provided with a fixed clip 105 and a movable clip 106, a fixed plate 107 is provided below the rectangular block 102, the rectangular block 102 has a mounting groove 108, the mounting groove 108 is provided with a plurality of first teeth 109, the mounting block 101 is slidably connected with the rectangular block 102, and is sleeved on the rectangular block 102, and the adjustment mechanism 103 is connected with the rectangular block 102. The first teeth 109 corresponding to the first teeth 109 are mutually abutted and located between the plurality of the teeth, the movable clamp 106 is slidably connected to the fixed block 104 and is located above the fixed block 104, the device is fixed to the edge of the operating table by the fixing mechanism, and then the catheter is placed between the fixed clamp 105 and the movable clamp 106, thereby playing a fixing role, and then the adjusting mechanism 103 is pulled to move the adjusting mechanism 103 out of the plurality of the first teeth 109, and then the mounting block 101 is moved up and down until it is adjusted to a suitable height.

[0027] The screw 119 is provided with a limiting ring 112, the first L-shaped block 110 has a cavity 113, the second L-shaped block 111 has a thread groove 114, the fixing plate 107 has a limiting groove 115, the screw 119 is rotatably connected to the first L-shaped block 110 and passes through the first L-shaped block 110 and the fixing plate 107, and the limiting ring 112 is located in the limiting groove 115, the screw 119 is also threadedly connected to the second L-shaped block 111 and is located in the thread groove 114, the first L-shaped block 110 is fixedly connected to the fixing plate 107 and is located below the fixing plate 107. The second L-shaped block 111 is slidably connected to the first L-shaped block 110 and is located in the cavity 113. By splitting the C-shaped block into the structure of the first L-shaped block 110 and the second L-shaped block 111, the contact area with the edge of the operating bed is increased. The distance between the two is adjusted by the screw 119, so that the first L-shaped block 110 and the second L-shaped block 111 are fixed to the edge of the operating bed. This fixing method effectively prevents loosening.

[0028] Secondly, the second L-shaped block 111 has positioning grooves 117 on both sides, and the two positioning rods 116 are fixedly connected to the first L-shaped block 110 and located in the cavity 113. The two positioning rods 116 are also slidably connected to the second L-shaped block 111 and located in the corresponding positioning grooves 117. The positioning rods 116 can improve the stability between the first L-shaped block 110 and the second L-shaped block 111.

[0029] Again, both the first L-shaped block 110 and the second L-shaped block 111 are provided with anti-skid pads 118 , and the anti-skid pads 118 can increase friction to reduce movement of the device.

[0030] When the utility model is used to fix the device, the screw 119 is rotated so that the screw 119 transmits the second L-shaped block 111 under the action of the limiting ring 112, so that the second L-shaped block 111 moves in the cavity 113. When adjusted to a suitable size, the first L-shaped block 110 and the second L-shaped block 111 are placed on the edge of the operating bed, and the screw 119 is rotated in the opposite direction so that the distance between the first L-shaped block 110 and the second L-shaped block 111 is slowly shortened, thereby achieving a fixing effect. Moreover, under the action of the anti-slip pad 118, the fixing effect on the edge of the operating bed can be improved. In this way, the technical problem that the U-shaped block is fixed to the edge of the operating bed by bolts, so that the contact area between the edge of the operating bed and the U-shaped block is small, and it is easy to loosen is solved.
