A return spring is fitted onto each guide rod. A locking groove is provided on each pressure block. Two sliding grooves are provided in the Z-shaped block, and locking blocks are slidably installed in each of the two sliding grooves. Springs are fitted onto the locking blocks.

[0007] The plastic tube contains a first pipe and a second pipe, and a first balloon and a second balloon are connected to the plastic tube.

[0008] In a preferred embodiment of this utility model, the Z-shaped block has two limiting grooves and two mounting grooves. One end of each pressing block is slidably installed in the corresponding limiting groove, and the other end is slidably installed in the corresponding mounting groove.

[0009] In a preferred embodiment of this utility model, the two connecting pipes are respectively connected to the first pipe and the second pipe.

[0010] In a preferred embodiment of this utility model, square grooves are provided on both pressure blocks.

[0011] In a preferred embodiment of this utility model, the plastic tube is provided with a first liquid outlet and a second liquid outlet. The first liquid outlet is interconnected with the first pipe and the first balloon, and the second liquid outlet is interconnected with the second pipe and the second balloon.

[0012] In a preferred embodiment of this utility model, a guide wire is installed in the plastic tube.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention enables precise positioning through the first and second balloons, ensures accurate injection of contrast agent through the inlet channel, and controls the injection of contrast agent through the Z-shaped block and pressure block for easy adjustment.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 7 As shown, a sterile balloon device for ultrasound exploration in craniocerebral surgery includes a plastic tube 1, with two connecting tubes 6 connected to the end of the plastic tube 1. Each of the two connecting tubes 6 is connected to a liquid inlet pipe 7. A Z-shaped block 8 is set between the two liquid inlet pipes 7. Two pressure blocks 10 are slidably installed in the Z-shaped block 8. Each pressure block 10 has two guide grooves 11. Each guide groove 11 has a guide rod 12 slidably installed. Each guide rod 12 is fitted with a reset spring 13. Each pressure block 10 has a locking groove 17. The Z-shaped block 8 has two sliding grooves 14. Each sliding groove 14 has a locking block 15 slidably installed. A spring 16 is fitted on the locking block 15.

[0027] The plastic tube 1 has a first pipe 4 and a second pipe 5 inside, and a first balloon 2 and a second balloon 3 are connected to the plastic tube 1. In this setup, the plastic tube 1 serves as the main body connecting all components. The connecting tube 6 connects the end of the plastic tube 1 to the inlet pipe 7, allowing the contrast agent to flow smoothly from the inlet pipe 7 to the first pipe 4 and the second pipe 5. The inlet pipe 7 is responsible for injecting the contrast agent. The Z-shaped block 8 is equipped with components such as the pressure block 10 and the locking block 15, which play a key role in controlling the injection of the contrast agent. The pressure block 10 can quickly stop the injection of the contrast agent, thereby controlling the dosage and avoiding excessive contrast agent from causing adverse effects on the surgery. It also facilitates the doctor to adjust the surgical plan when the surgical situation changes. When the pressure block 10 is pressed, it slides in the limiting groove 9 and the mounting groove 18. The guide rod 12 slides into the guide groove 11. The guide groove 11 and the guide rod 12 provide guidance for the sliding of the pressure block 10, ensuring the accuracy of the movement of the pressure block 10. The spring 16 can push the locking block 15 to the locking groove 17, thereby locking the pressure block 10. The reset spring 13 is compressed after the pressure block 10 is pressed, and the pressure block 10 can be reset when unlocked.

[0028] like Figures 1 to 7 As shown in the specific embodiment, the Z-shaped block 8 has two limiting grooves 9 and two mounting grooves 18. Each pressure block 10 has one end slidably mounted in the corresponding limiting groove 9 and the other end slidably mounted in the corresponding mounting groove 18. In this configuration, the mounting grooves 18 and limiting grooves 9 provide sliding mounting positions for both ends of the pressure block 10, ensuring the stability of the movement of the pressure block 10, facilitating precise control of contrast agent injection, and making it convenient for doctors to operate and adjust the surgical plan.

[0029] like Figures 1 to 7 As shown, furthermore, the two connecting pipes 6 are connected to the first pipe 4 and the second pipe 5 respectively. In this configuration, the connecting pipe 6 connects the end of the plastic pipe 1 to the liquid inlet pipe 7, so that the contrast agent can flow smoothly from the liquid inlet pipe 7 to the first pipe 4 and the second pipe 5.

[0030] like Figures 1 to 7 As shown, square grooves 19 are provided on both pressure blocks 10. In this configuration, the square grooves 19 allow the two pressure blocks 10 to slide smoothly and prevent them from blocking each other.

[0031] like Figures 1 to 7 As shown, the plastic tube 1 has a first outlet 21 and a second outlet 22. The first outlet 21 is interconnected with the first pipe 4 and the first balloon 2, and the second outlet 22 is interconnected with the second pipe 5 and the second balloon 3. In this configuration, the first outlet 21 and the second outlet 22 respectively connect the first pipe 4 to the first balloon 2 and the second pipe 5 to the second balloon 3, ensuring that the contrast agent flows accurately into the balloon.

[0032] like Figures 1 to 7 As shown, a guide wire 20 is installed in the plastic tube 1. In this setup, the guide wire 20 further ensures the accuracy and stability of the placement of the first balloon 2 and the second balloon 3, providing a reliable guarantee for the smooth progress of the surgery.

[0033] The implementation principle of a sterile balloon device for ultrasound exploration in craniocerebral surgery according to this embodiment is as follows: During the surgical procedure, the second balloon 3 is accurately placed at the lesion site in the brain, and the first balloon 2 is placed along the path. Contrast agent is then injected into the two inlet channels 7. The contrast agent flows into the first channel 4 and the second channel 5 via the connecting tube 6, and then enters the first balloon 2 from the first outlet 21 and the second balloon 3 from the second outlet 22, causing both balloons to inflate. After being filled with contrast agent, the first balloon 2 and the second balloon 3 are arc-shaped, providing the surgeon with more operating space. A Z-shaped block 8 is provided between the two inlet channels 7. Pressing the pressure block 10 on it can quickly stop the injection of contrast agent. This operation can control the dosage, avoid excessive injection of contrast agent, and prevent adverse effects on the surgery due to excessive contrast agent. If any situation occurs during the surgery... Changes in the pressure block 10 allow for timely cessation of contrast agent injection, facilitating flexible adjustments to the surgical plan by the surgeon based on the actual situation. When the pressure block 10 is pressed, the locking block 15 compresses the inlet pipe 7, preventing further flow of the contrast agent and stabilizing the pressure in the first balloon 2 and the second balloon 3, thus making the surgery more stable. Ultrasound can be used to locate the contrast agent, allowing the surgeon to precisely operate along the path of the contrast agent and the location of the lesion during the resection procedure, maximizing the safety of the surgery. After pressing the pressure block 10, it slides in the limiting groove 9 and the mounting groove 18, the guide rod 12 slides into the guide groove 11, and the return spring 13 is compressed. Then, the spring 16 pushes the locking block 15 into the locking groove 17, thereby locking the pressure block 10. Unlocking is achieved by simply pulling the locking block 15. When the locking block 15 leaves the locking groove 17, the return spring 13 resets the pressure block 10.
