[0002] The balloon dilatation catheter is an interventional medical device that can perform targeted treatment on the diseased areas of the body's tubular tissue structure. It has the characteristics of small incisions and high surgical success rate.

[0003] At present, most balloon dilatation catheters are of fixed length, which means that in actual use, the catheter will be designed to be very long. Too long a length will cause excess parts to be redundant outside the patient's body, thus affecting the progress of the operation. There are certain shortcomings in its use. For this reason, we propose a catheter for peripheral balloon dilatation. Utility Model Content

The locking bolt passes through the reeling frame and is locked with the unreeling mechanism. A fixing sleeve is fixed inside the reeling frame, and a catheter body is passed through and fixed inside the fixing sleeve.

[0009] Preferably, the locking bolt passes through the winding frame and is connected to the turntable through threads.

[0010] Preferably, the catheter body is rolled up on a rolling frame, and a connector and a balloon are respectively installed at both ends of the catheter body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model drives the reeling frame by arranging an unwinding mechanism, and utilizes the reeling frame to reel in and unwind the catheter body, so that the length of the catheter can be flexibly adjusted, and then redundant catheter bodies can be stored conveniently.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-3A catheter for peripheral balloon dilatation includes a support frame 1, which is an L-shaped structure. A reeling mechanism 2 is fixed to the side of the support frame 1. The reeling mechanism 2 is inserted into the interior of the support frame 1 and is rotatably connected thereto. A reeling frame 3 is clamped on the reeling mechanism 2, and a locking bolt 4 is installed inside the reeling frame 3. The reeling mechanism 2 includes a shell 21 fixed to the support frame 1, and a worm 22 and a rotating shaft 23 are rotatably connected inside the shell 21. A worm wheel 24 is fixed on the rotating shaft 23. The rotating shaft 23 is inserted into the interior of the support frame 1 and is connected to a turntable 25. The worm wheel 24 and the worm 22 are meshed transmission. One end of the worm 22 passes through the shell 21 and is connected to a knob. The locking bolt 4 The bolt 4 passes through the winding frame 3 and is connected to the turntable 25 through a thread. The locking bolt 4 passes through the winding frame 3 and is locked with the unwinding mechanism 2. A fixing sleeve 5 is fixed inside the winding frame 3. A catheter body 6 is passed through and fixed inside the fixing sleeve 5. The catheter body 6 is wound on the winding frame 3. A connector 7 and a balloon 8 are respectively installed at both ends of the catheter body 6. The unwinding mechanism is provided to drive the winding frame, and the winding frame is used to wind and unwind the catheter body, so that the length of the catheter can be flexibly adjusted, and then it is convenient to store redundant catheter bodies. The device has a simple structure, can effectively avoid the risk of the catheter body being too long, and has very high safety in use.

[0019] When in use, the catheter body 6 passes through the fixed sleeve 5, and then the knob is rotated to rotate the worm 22. The worm 22 drives the rotating shaft 23 to rotate through the meshing transmission with the worm wheel 24. The rotating shaft 23 drives the turntable 25 to rotate. The turntable 25 drives the winding frame 3 to rotate. The catheter body 6 is wound up by the winding frame 3, and then the connector 7 and the balloon 8 are installed at both ends of the catheter body 6. When in use, the knob is rotated in the opposite direction to make the winding frame 3 rotate in the opposite direction, and then the catheter body 6 is unwound. The length of the catheter body 6 is adjusted as needed, which can effectively avoid the risk of the catheter body being too long, and the safety of use is very high.
