[0002] Abdominal cysts often present with abdominal masses or abdominal pain as their main clinical manifestations. They can be correctly diagnosed through abdominal ultrasound or CT scan, but it is sometimes difficult to identify the location or nature of the cyst.

[0003] In clinical work, a guidewire is used to locate and search for cysts in the patient's abdominal cavity. However, this method of positioning and searching is inaccurate, which will cause positioning deviation and lead to the failure of guidewire positioning. At this time, the doctor needs to make multiple guidewire positioning judgments to complete it. This operation method is time-consuming and labor-intensive, which not only increases the difficulty of the doctor's work, but also reduces medical progress. In view of the above defects, it is necessary to design a composite balloon device for intracavitary guidewire capture. Summary of the Invention

[0020] The following specific embodiments will be further described in conjunction with the above drawings. SPECIFIC EMBODIMENTS

[0021] In the following text, a variety of specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. However, it will be apparent to those skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well-known processing steps have not been described in detail.

[0022] Embodiment 1

[0023] As Figure 1As shown, a composite balloon device for intracavitary wire capture includes a catheter 1. An expansion mechanism 2 is slidably disposed inside the catheter 1. A drive handle 3 for controlling the operation of the expansion mechanism 2 is rotatably provided on the right side of the catheter 1. A liquid injection mechanism 4 is integrally provided inside the expansion mechanism 2. A linkage mechanism 5 is threadedly penetrated through the lower end on the right side of the catheter 1. An unfolding mechanism 6 is fixedly provided on the left side inside the linkage mechanism 5.

[0024] For this composite balloon device for intracavitary wire capture, the doctor first moves the wire into the expansion mechanism 2. With the assistance of an ultrasonic imaging device, the doctor then percutaneously punctures the left side of the wire together with the catheter 1 into the cyst site in the patient's abdominal cavity. The doctor then rotates the drive handle 3 clockwise with the other hand, so that the left end of the expansion mechanism 2 is moved out from the left end inside the catheter 1. The doctor then injects liquid into the expansion mechanism 2 through the liquid injection mechanism 4. The doctor then uses the linkage mechanism 5 to move the unfolding mechanism 6 into the expansion mechanism 2. At this time, the unfolding mechanism 6 moved into the expansion mechanism 2 is in an expanded state, which facilitates the doctor to subsequently use the wire at the endoscope to hook the expanded unfolding mechanism 6. The doctor can then conveniently remove the hooked wire through the cyst site in the patient.

[0025] Embodiment 2

[0026] As Figure 1 、 Figure 2 、 Figure 3As shown, a composite balloon device for capturing an intracavitary guidewire comprises a catheter 1, wherein the catheter 1 is provided with a telescopic mechanism 2 for sliding inside, a driving handle 3 for controlling the operation of the telescopic mechanism 2 for rotating on the right side of the catheter 1, an injection mechanism 4 is provided inside the telescopic mechanism 2, a linkage mechanism 5 is threaded through the lower end of the right side of the catheter 1, an expansion mechanism 6 is fixedly provided on the left side of the linkage mechanism 5, the telescopic mechanism 2 is composed of a slider 7, a connecting rod 8, a balloon 9 and a clearance hole 10, a slider 7 is provided for sliding on the upper end of the catheter 1, a connecting rod 8 is fixedly provided at the bottom of the slider 7, the connecting rod 8 penetrates the catheter 1, and the connecting rod 8 is threaded through the driving handle 3, a balloon 9 is provided on the left side of the sealing fixing sleeve outside the connecting rod 8, a clearance hole 10 is provided on the lower end of the connecting rod 8, and the injection mechanism 4 is composed of an injection mechanism The connecting rod 8 is composed of a hole 11, a pipe 12 and a valve 13. The upper end of the connecting rod 8 is integrally provided with a liquid injection hole 11. The right side of the top of the connecting rod 8 is sealed and fixed with a pipe 12. The outer wall of the pipe 12 is fixed with a valve 13. The linkage mechanism 5 is composed of a rotating rod 14 and a sliding rod 15. The lower right end of the catheter 1 is threaded with a rotating rod 14. The sliding rod 15 is provided with a sliding sleeve on the left side of the rotating rod 14, and the sliding rod 15 is rotatably connected to the rotating rod 14. The other end of the sliding rod 15 is sealed and fixed to the balloon 9. The deployment mechanism 6 is composed of a spring 16 and a basket 17. Four springs 16 are fixed around the left side of the rotating rod 14. The angle between the two springs 16 is 90°. The left end of the spring 16 is fixed with a basket 17, and the other end of the basket 17 is fixedly connected to the rotating rod 14.

[0027] Before use, the composite balloon device for capturing an intracavitary guidewire is arranged such that the mesh basket 17 is first placed inside the slide bar 15, so that the slide bar 15 applies squeezing force to the mesh basket 17, i.e., the mesh basket 17 is in a contracted state and the spring 16 is in a deformed state. When in use, the doctor first moves the guidewire into the clearance hole 10, and with the assistance of ultrasound imaging equipment, the doctor then percutaneously punctures the guidewire together with the left side of the catheter 1 into the cyst site in the patient's abdominal cavity. The doctor then uses the other hand to rotate the driving handle 3 forward, and through the threaded transmission of the driving handle 3 and the connecting rod 8, the driving handle 3 drives the connecting rod 8 and the balloon 9 together with the slider 7 and the slide bar 15 to move from right to left along the direction of the catheter 1, thereby moving the balloon 9 out from the left end inside the catheter 1, i.e., the balloon 9 is inside the cyst. The doctor then Liquid is injected into the balloon 9 through the injection hole 11 from the pipe 12, causing the balloon 9 to expand. After the injection is completed, the doctor first manually closes the valve 13 and then manually rotates the rotating rod 14. Through the threaded transmission of the rotating rod 14 and the catheter 1, the rotating rod 14 drives the basket 17 through the inside of the slide rod 15 and moves it into the balloon 9. When the basket 17 moves into the balloon 9, the squeezing force of the slide rod 15 on the basket 17 is eliminated. The spring 16 acts to make the basket 17 in an expanded state inside the balloon 9, making it easier for the doctor to use the guide wire at the endoscope to first puncture the inflated balloon 9. The guide wire punctured into the balloon 9 is then hooked with the basket 17 that has been expanded in the balloon 9. The doctor can then easily remove the hooked guide wire from the patient's cyst. The front end of the basket 17 is wavy and S-shaped, which is intended to ensure the convenience of hooking the guide wire at the endoscope with the basket 17.
