Description

Technical Field

[0001] The present invention relates to the technical field of vascular dilation devices, in particular to a vascular dilation device. Background Art

[0002] When performing vascular interventional treatment on patients, a vascular dilation device is required. A balloon catheter is inserted into the narrowed blood vessel through vascular puncture. The balloon is pressurized and expanded outside the body to expand the narrowed blood vessel wall and relieve the stenosis of the diseased blood vessel.

[0003] Current vasodilator devices have certain shortcomings:

[0004] 1. When dilating blood vessels, it is generally done through a balloon. However, when the balloon dilates the blood vessels, it is easy to cause blood flow interruption and block the patient's blood circulation. At the same time, some balloons do not have sufficient support for the blood vessels, and the vascular dilation effect is poor.

[0005] 2. At the same time, when the expansion device is filled with liquid, the supporting force required for the balloon support is inconsistent with the supporting force at other positions, and the required liquid volume is inconsistent. However, the existing method generally fills the liquid through a liquid inlet hole so that the supporting force at each position is consistent.

[0006] 3. At the same time, after the support is used, the expansion device needs to be drained. However, the existing method is generally to extract the liquid by extraction. Moreover, when the balloon model is large (tube diameter, length) or the balloon filling fluid is thick, it will take a certain amount of time to extract, which increases the operation time and the risk of related operations.

[0021] The present invention provides a vasodilator having the following beneficial effects:

[0022] 1. The present invention provides four groups of through grooves on the outside of the support balloon, so that when the support balloon supports one end of the blood vessel, blood can flow smoothly through the through grooves to prevent blood flow blockage. At the same time, through the mutual cooperation between the liquid inlet sleeve and the telescopic rod, the arc-shaped support plate can be pushed toward the inner wall of the blood vessel for support, and blood vessels in different areas can be supported, so that the blood vessel expansion device can flexibly adapt to the support requirements of different areas.

The present invention generates negative pressure inside the piston cylinder, which can quickly extract the liquid inside the first liquid inlet pipe and the second liquid inlet pipe, and insert the piston sealing rod into the interior of the discharge sleeve to seal the discharge sleeve. At this time, pulling the pull rod drives the negative pressure piston to move upward inside the piston cylinder until the negative pressure piston moves to the highest point.

When it is necessary to extract liquid from the first liquid inlet pipe and the second liquid inlet pipe, the liquid can be quickly transferred to the interior of the piston cylinder, reducing the drainage time.

[0046] As a preferred solution of this embodiment: the drain sleeve 201 and the liquid inlet mounting tube 301 are integrally formed on the first liquid inlet tube 1 and the second liquid inlet tube 11, so that the sealing effect between the drain sleeve 201 and the liquid inlet mounting tube 301 and the first liquid inlet tube 1 and the second liquid inlet tube 11 is better.

[0047] As a preferred solution of this embodiment: a guide ring is provided at the bottom of a group of through grooves 9 to facilitate the support of the balloon 7 to be delivered to the lesion site through the guide wire.

[0048] Example 1, as Figure 4 As shown, when it is necessary to drain the interior of the first liquid inlet pipe 1 and the second liquid inlet pipe 11, the piston sealing rod 206 is inserted into the interior of the drainage sleeve 201 to seal the drainage sleeve 201. At this time, the pull rod 209 is pulled to drive the negative pressure piston 205 to move upward inside the piston cylinder 207 until the negative pressure piston 205 moves to the highest point. At this time, a vacuum is formed inside the piston cylinder 207 to generate negative pressure. Then the clamping rod 203 is inserted into the interior of the clamping groove 202 to fix it. When it is necessary to draw liquid from the first liquid inlet pipe 1 and the second liquid inlet pipe 11, the piston sealing rod 206 is pulled out of the interior of the drainage sleeve 201, which can quickly transfer the liquid to the interior of the piston cylinder 207, thereby reducing the drainage time.

[0049] Example 2, as Figure 1 and 5 As shown, when it is necessary to fill the first liquid inlet pipe 1 and the second liquid inlet pipe 11 with liquid in sequence, the movable sleeve 305 is pulled downward to drive the movable hole 307 to move to the third liquid through hole 306, so that the third liquid through hole 306 and the movable hole 307 overlap with each other, and then the fixing rod 303 is inserted into the fixing groove 304 to fix the movable sleeve 305, and the second liquid inlet pipe 11 can be filled with liquid. The liquid enters the interior of the liquid inlet sleeve 10 to support the telescopic rod 4, so that the telescopic rod 4 moves inside the liquid inlet sleeve 10. The arc-shaped support plate 6 is supported and expanded by the top plate 5 to support the inner wall of the blood vessel. At the same time, when the movable hole 307 overlaps with the second liquid through hole 302, the support balloon 7 can be supported, and the through groove 9 allows blood to pass through to prevent blockage of the blood vessel.

[0050] Working principle: Four groups of through grooves 9 are provided on the outside of the support balloon 7, so that when the support balloon 7 supports one end of the blood vessel, blood can flow smoothly through the through grooves 9 to prevent blood flow blockage. At the same time, through the mutual cooperation between the liquid inlet sleeve 10 and the telescopic rod 4, the arc-shaped support plate 6 can be pushed toward the inner wall of the blood vessel for support, and blood vessels in different areas can be supported, so that the blood vessel expansion device can flexibly adapt to the support requirements of different areas.

[0051] When the expansion device needs to support different areas, the movable sleeve 305 is connected to the external liquid filling device. When the interior of the support balloon 7 needs to be filled with liquid, the movable sleeve 305 can be pushed upward at this time, so that the movable sleeve 305 drives the movable hole 307 to overlap with the second liquid hole 302. The movable sleeve 305 is connected to the interior of the first liquid inlet pipe 1, and the movable sleeve 305 is fixed through the cooperation of the fixing rod 303 and the fixing groove 304, and the interior of the support balloon 7 is filled with liquid to support the lesion of the blood vessel. The movable hole 307 is overlapped with the third liquid hole 306 to overlap the interior of the second liquid inlet pipe 11.

[0052] Insert the piston sealing rod 206 into the interior of the drain sleeve 201 to seal the drain sleeve 201. At this time, pull the pull rod 209 to drive the negative pressure piston 205 to move upward inside the piston cylinder 207 until the negative pressure piston 205 moves to the highest point. At this time, negative pressure is generated inside the piston cylinder 207. Then insert the clamping rod 203 into the interior of the clamping groove 202 to fix it. When it is necessary to draw liquid from the first liquid inlet pipe 1 and the second liquid inlet pipe 11, pull the piston sealing rod 206 out of the interior of the drain sleeve 201, which can quickly transfer the liquid to the interior of the piston cylinder 207 and reduce the drainage time.

[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
