Description

Technical Field

[0001] This utility model belongs to the field of pressure gripping tooling technology, specifically relating to a balloon pressure gripping tooling for a guide tube. Background Technology

[0002] The balloon clamping fixture for guiding balloon catheters is a key instrument used to assist in the operation of balloon guiding catheters. It is a specialized tool for precisely assembling the balloon catheter and balloon assembly and controlling the balloon inflation state. Based on mechanical pressure and fluid control technology, the fixture uses a clamp to fix the balloon catheter, and an inflation device to inject gas into the balloon, inflating it to a preset pressure value. Simultaneously, a pressure gauge monitors and maintains a stable pressure in real time, ensuring the accuracy and safety of the balloon-catheter connection. The balloon clamping fixture enables standardized assembly of balloon guiding catheters, improving the compatibility and operational stability of surgical instruments.

[0003] In practical use, existing guide tube and balloon compression fixtures mainly rely on their own structure to assemble the guide tube and balloon. However, during this assembly process, manual pushing of the guide tube and balloon is required to achieve compression at other positions. Manual pushing has obvious drawbacks. On the one hand, it is difficult to ensure that the distance moved each time is accurate and consistent, which may lead to uneven compression at different positions of the balloon, thus adversely affecting the performance and effectiveness of the balloon. On the other hand, the manual pushing speed is relatively slow, which reduces the overall efficiency of compression of the guide tube and balloon. These shortcomings make the guide tube and balloon compression device somewhat lacking in practicality. Utility Model Content

[0018] Specifically, such as Figure 1 As shown, a rectangular groove is provided on one side of the bearing plate 3, and a rectangular plate 9 adapted to the rectangular groove is provided at the bottom of the mounting base 5. The bottom end of the rectangular plate 9 is located in the rectangular groove and is slidably connected to the side wall of the rectangular groove. A first electric push rod 10 is provided on one side of the upper end of the base 1. The first electric push rod 10 is the prior art and will not be described in detail here. The output end of the first electric push rod 10 is located on one side of the rectangular plate 9.

[0019] Through its design, when the first electric push rod 10 is started, its output end will drive the rectangular plate 9 and the mounting base 5 to move, thereby driving the limit plate 6 to move. This can conveniently and stably drive the guide tube and balloon to move, ensuring the quality and efficiency of their pressure, and making the balloon pressure device of the guide tube more practical.

[0020] Specifically, such as Figure 2 As shown, a positioning groove is provided on one side of the piston chamber, and a second electric push rod 11 is provided on one side of the positioning groove.

Example 2

[0024] Please see Figure 1-4 This utility model provides a balloon gripping tool for a guide tube, comprising: Base 1 and control panel 2; The support plate 3 is located on one side of the upper end of the base 1, the control panel 2 is located on the other side of the upper end of the base 1, and the support plate 3 is provided with a gripping component 4 on one side of the upper end.

[0025] Specifically, such as Figure 2 and Figure 4 As shown, the upper end of the mounting base 5 is provided with a mounting groove, and the bottom end of the mounting groove is rotatably connected to a threaded rod 17. The bottom end of the limiting plate 6 is provided with a mounting rod 18 that is compatible with the mounting groove.

[0028] See Figure 1-4 When using the balloon compression device with the guide tube, first rotate the threaded rod 17 according to the size specifications of the guide tube and balloon. The threaded rod 17 will drive the mounting rod 18 and the limiting plate 6 to move up and down to adapt to guide tubes and balloons of different sizes. When limiting the position of the guide tube and balloon, they need to be placed in the limiting port. Then, start the second electric push rod 11. The output end of the second electric push rod 11 will drive the first piston plate 12 to move, thereby changing the air pressure in the piston chamber and the two air chambers. When the air pressure in the piston chamber and the two air chambers changes, it will simultaneously drive the two second piston plates 13 to move. The two second piston plates 13 will drive the two guide plates 14 to move respectively. In conjunction with the inclined guide port, they can drive the two guide shafts 15 and the two drive plates 8 to move up and down respectively. The two drive plates 8 will drive the two clamping plates 7 to move respectively, which can firmly limit the position of the guide tube and the balloon. Then, one end of the guide tube and the balloon is placed in the pressure assembly 4 for pressure operation. By activating the first electric push rod 10, the mounting base 5 and the limiting plate 6 can be moved, thereby driving the guide tube and the balloon to move, ensuring the quality of the pressure assembly 4 in the pressure of the balloon pressure device of the guide tube.
