[0002] Balloon compression is a common interventional procedure that is widely used in neurology and gastroenterology. For example, balloon compression of the trigeminal ganglion can effectively treat trigeminal neuralgia. The usual steps of this procedure are as follows: Under local anesthesia, a puncture needle is passed through the foramen ovale on the face to insert the balloon into the wound cavity, and liquid is injected into the balloon catheter to inflate the balloon at the target position. The balloon expansion compresses the nerve for about 2 to 3 minutes to achieve pain treatment.

[0003] The balloon catheters currently in use are all of fixed size and length, which are difficult to meet the needs of individualized precision treatment. At the same time, the size of existing balloons is difficult to change, and the problem of balloon eccentricity is prone to occur, making it difficult for the balloon to present the optimal "pear-shaped" effect state.

[0020] The balloon colloid 36 is specifically composed of a high-elastic rubber layer 361 and a resin glue layer 362 pressed together, and a stretched fiber mesh 363 is sandwiched in the gap between the high-elastic rubber layer 361 and the resin glue layer 362; the bottom of the stretched fiber mesh 363 is fixedly connected to the elastic wire 34 through fibers; and the surface of the resin glue layer 362 is coated with a protective drug coating 364.

[0021] The elastic wire 34 and the balloon colloid 36 are both pear-shaped, and eight groups of elastic wires 34 are arranged inside the balloon colloid 36; the balloon colloid 36 and the side rubber layer 37 have the same overall structure, and the side rubber layer 37 at the left end of the catheter body 2 is in an arc shape.

[0022] Embodiment 2: See also Figure 1~Figure 5 Compared with the first embodiment, the trigeminal ganglion compression device of the present invention further includes: a detection component 38 includes a terminal shell 381 fixedly mounted on the left side of the fixed sealing plate 35, and a side rubber layer 37 is fixedly sleeved on the outer surface of the terminal shell 381; a small airbag is arranged inside the terminal shell 381, and a piston plate 382 is adhesively arranged on the right side of the small airbag; a pressure detector 383 for detection is fixedly mounted on the left side of the terminal shell 381, and the pressure detector 383 is connected to the air port of the airbag inside the terminal shell 381; the expansion and stretching coefficient of the small airbag inside the terminal shell 381 is the same as that of the balloon colloid 36.

[0023] The working principle of the trigeminal ganglion compression device based on the above is: First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation; Second, when in use, firstly, the surgical tool is used to complete the passage from the skin to the treatment position, and then the medical staff drives the balloon assembly 3 to the treatment position through the catheter fixing frame 1 and the catheter body 2, and controls the electromagnetic plate 39 to be energized according to the preoperative detection image data, so that the electromagnetic plate 39 is energized to push the magnetic sleeve 31 to slide on the catheter body 2, and then the magnetic sleeve 31 pushes the movable sealing plate 33 to move slightly through the fixed wire 32 to change the curvature of the elastic wire 34, thereby changing the pear-shaped size of the balloon colloid 36; Third, the developer is slowly injected into the balloon colloid 36 through the injection channel on the catheter body 2. At this time, the gas in the balloon colloid 36 is discharged through the discharge channel on the catheter body 2. Then, the discharge channel on the catheter body 2 is blocked, and the developer is continuously injected to expand the balloon colloid 36. Here, a drug coating 364 is provided on the balloon colloid 36 to reduce discomfort at the wound site. Fourth, the simultaneous detection component 38 detects the pressure inside the catheter body 2 in real time. After the discharge channel is blocked, the pressure inside the catheter body 2 and the balloon colloid 36 begins to rise. Here, the piston plate 382 sliding in the catheter body 2 is pressed against the airbag in the terminal shell 381. Since the expansion coefficients of the airbag in the terminal shell 381 and the balloon colloid 36 are the same, the pressure detector 383 detects the airbag pressure. Here, the pressure of the airbag is the internal pressure of the balloon colloid 36. Finally, the balloon colloid 36 is kept expanded to compress the trigeminal ganglion for 3 to 7 minutes, and then the contrast agent is extracted, and the operation is completed.

[0024] The present invention provides a trigeminal ganglion compression device through improvement. The gas and fluid inside the balloon component 3 are guided by setting injection and discharge channels inside the catheter body 2, and the movable sealing plate 33 changes the curvature of the elastic wire 34 through the magnetic repulsion of the electromagnetic plate 39 and the magnetic sleeve 31, so as to change the pear-shaped size of the balloon colloid 36. The drug coating 364 on the balloon colloid 36 is set to reduce the discomfort at the wound. At the same time, the detection component 38 performs real-time detection of the pressure inside the catheter body 2. The shape of the balloon can be accurately controlled by the cooperation of the elastic wire 34 and the pressure detector 383, and the treatment effect can be quantitatively evaluated, so that the trigeminal ganglion balloon compression surgery can be achieved. Rapid and accurate treatment, improve the disease cure rate, and reduce postoperative complications.
