DETAILED DESCRIPTION
[0022] See also Figure 1-4 , a fixing device for facilitating the disassembly of an internal fistula puncture needle, comprising a placement seat 1, an adjustment mechanism 2 is arranged inside the placement seat 1, and a reinforcement mechanism 3 is arranged above the placement seat 1;
[0023] The adjustment mechanism 2 includes two sliding blocks 201, each of which is slidably connected to the inside of the placement seat 1. The inner wall of each sliding block 201 is fixedly connected with a stabilizing block 4. Each stabilizing block 4 is slidably connected to the inside of the placement seat 1. The stabilizing block 4 can move simultaneously with the sliding block 201, and utilizes its own friction with the placement seat 1 during the movement to increase the force position of the stabilizing block 4 when moving, thereby effectively increasing the stability of the stabilizing block 4.
[0024] Two Velcro strips 202 are fixedly connected to the upper surface of each sliding block 201, and adjustment holes 203 arranged at equal distances are provided on the upper surface of the placement seat 1. An auxiliary handle 5 is fixedly connected to the front of each sliding block 201, and an anti-slip cover 6 is fixedly connected to the outer surface of each auxiliary handle 5. The auxiliary handle 5 can provide a good force point for the sliding block 201, thereby increasing the convenience when the sliding block 201 needs to be pushed, and the anti-slip cover 6 can increase the stability when grasping the auxiliary handle 5.
[0025] A fixing bolt 204 is arranged above each sliding block 201, and the bottom end of each fixing bolt 204 passes through one of the adjustment holes 203 and is threadedly connected to the sliding block 201. Two reinforcement rings 7 are fixedly connected to the outer surface of each auxiliary handle 5, and one end of each reinforcement ring 7 close to the sliding block 201 is fixedly connected to the front side of the sliding block 201. The reinforcement ring 7 can increase the fixed connection area between the auxiliary handle 5 and the sliding block 201, thereby increasing the firmness of the auxiliary handle 5 and preventing the auxiliary handle 5 from loosening after long-term use.
[0026] The reinforcement mechanism 3 includes two support blocks 301, the front side of each support block 301 is fixedly connected to the back side of the placement seat 1, the front side of the placement seat 1 is fixedly connected to two auxiliary blocks 302, the upper surface of each support block 301 is fixedly connected to a fixing belt 303, the end of each fixing belt 303 away from the support block 301 passes through the two auxiliary blocks 302 in sequence and extends to the bottom of the auxiliary block 302, the outer surface of each fixing belt 303 is provided with fixing holes 304 arranged at equal distances, the inner wall of the placement seat 1 is fixedly connected to a first sponge pad 11, and the inner top wall of each fixing belt 303 is fixedly connected to a second sponge pad 12. Relying on the cooperation of the limit ring 9 and the handle 10, the convenience when pulling the transmission block 306 can be effectively improved, and the limit ring 9 and the transmission block 306 can be driven to move by pulling the handle 10, thereby increasing the convenience of the device.
[0027] Two limit rods 305 are slidably connected to the interior of each auxiliary block 302, and the end of each group of limit rods 305 close to the auxiliary block 302 passes through one group of fixing holes 304 and the auxiliary block 302 in sequence and extends to the interior of the auxiliary block 302, and the end of each group of limit rods 305 away from the auxiliary block 302 is fixedly connected to a transmission block 306, and the end of each transmission block 306 away from the limit rod 305 passes through the auxiliary block 302 and extends to the front of the auxiliary block 302, and the inner wall of each transmission block 306 is fixedly connected to two return springs 8, and the end of each group of return springs 8 away from the limit rod 305 is fixedly connected to the inner wall of the auxiliary block 302, and the return spring 8 can push the transmission block 306 to move through its own telescopic ability, so that the limit rod 305 can achieve the ability of automatic reset, thereby increasing the speed when limiting the fixing belt 303.
[0028] One end of each transmission block 306 away from the limiting rod 305 is fixedly connected to the limiting ring 9, and one end of each limiting ring 9 away from the auxiliary block 302 is fixedly connected to the handle 10. Relying on the cooperation between the limiting ring 9 and the handle 10, the convenience when it is necessary to pull the transmission block 306 can be effectively improved. By pulling the handle 10, the limiting ring 9 and the transmission block 306 can be driven to move, thereby increasing the convenience of the device.
[0029] The working principle of the utility model is as follows: when in use, first place the patient's arm on the upper surface of the first sponge pad 11 in the placement seat 1. The first sponge pad 11 can increase the softness of the placement seat 1. At this time, turn the fixing bolt 204 to remove it from the adjustment hole 203 and the inside of the placement seat 1, so that the sliding block 201 is in an unobstructed state, and then push the auxiliary handle 5, and use the auxiliary handle 5 to drive the sliding block 201 and the Velcro 202 to move inside the placement seat 1. When the Velcro 202 is suitable for the patient's puncture position, it can be stopped, and then the fixing bolt 204 is inserted into the relative adjustment hole 203 and the sliding block 201 to prevent the adjusted sliding block 201 from moving, and then fix the puncture needle with the Velcro 202. When the patient's arm needs to be fixed, pull the grip 10, rely on the grip 10 to drive the limit ring 9 to move, and then drive the transmission block 30 The second sponge pad 12 can reduce the discomfort caused by the fixing belt 303 to the patient when the fixing belt 303 is fixed. When the fixing belt 303 is of appropriate tightness, the grip 10 can be loosened. At this time, the reset spring 8 can rely on its own expansion and contraction ability to push the transmission block 306 to move, thereby allowing the limiting rod 305 to be inserted into the fixing hole 304 again and limit the position of the fixing belt 303. When the device needs to be disassembled, tear off the Velcro 202 to release the fixation of the puncture needle, and then pull the grip 10 to drive the limiting rod 305 to move out of the fixing hole 304, and loosen the fixing belt 303. This not only improves the applicability of the internal fistula puncture needle fixing device, but also increases the use effect of the internal fistula puncture needle fixing device.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
