Embodiment 1

[0027] like figure 1 and 2 As shown, a percutaneous coronary intervention device for treating acute coronary syndrome includes a device main body 1, one end of the device main body 1 is mounted with a first catheter 2, and the first catheter 2 is away from one end of the device main body 1 A second catheter 3 is installed, the outer wall of the second catheter 3 is sleeved with a balloon 4, and the inner wall of the balloon 4 is provided with an inflation device; during treatment, the second catheter 3 and the balloon 4 can be placed along the The femoral artery and the blood vessel enter the coronary artery, and then the inside of the balloon 4 is inflated through the inflation device, so as to expand the blood vessel and realize the inflation of the inside of the balloon 4 .

[0028] like figure 2 and Image 6 , the inflatable device includes a fourth conduit 5 installed on the inner wall of the balloon 4, an injection device 6 is installed at one end of the fourth condu...

Embodiment 2

[0031] like image 3 As shown, this embodiment further describes Embodiment 1, the connecting mechanism includes a second gear 16 and a third gear 17 mounted on the outer wall of the first rotating shaft 14, and both the second gear 16 and the third gear 17 pass through The bearing is connected with the first rotating shaft 14, the side walls of the second gear 16 and the third gear 17 are respectively meshed with the fourth gear 18 and the fifth gear 19, and the fourth gear 18 and the fifth gear 19 are sleeved on the On the outer wall of the second rotating shaft 15, the fourth gear 18 and the fifth gear 19 are connected to the first rotating shaft 14 through bearings, and an adjustment mechanism is arranged between the fourth gear 18 and the fifth gear 19, which can be adjusted between the fourth gear 18 and the fifth gear 19. When it is necessary to control the accuracy of gas entry, the sixth gear 21 can be meshed with the fifth gear 19 through the adjusting mechanism, so ...

Embodiment 3

[0034] like image 3 , Figure 4 and Figure 5 As shown, this embodiment further describes Embodiment 1. The adjusting mechanism includes a sixth gear 21 disposed on the outer wall of the second rotating shaft 15, and the sixth gear 21 is slidably connected to the second rotating shaft 15, so The side wall of the sixth gear 21 is provided with an annular groove 23, an arc-shaped block 24 is installed on the inner wall of the annular groove 23, and a second connecting rod 25 is installed on the top of the arc-shaped block 24. The second connecting rod A third connecting rod 26 is installed on one end of the 25 away from the arc-shaped block 24 , a third connecting rod 26 is installed on one side of the third connecting rod 26 , and one end of the third connecting rod 26 away from the second connecting rod 25 is installed There is a second control mechanism, which can drive the third connecting rod 26 to slide through the second control mechanism when adjusting the speed of ga...

Abstract

The invention discloses a percutaneous coronary intervention device for treating acute coronary syndrome, relates to the technical field of medical treatment, and aims at solving the problem that when an existing intervention device inflates the interior of a balloon, excessive gas in the balloon is likely to happen, and blood vessels are hurt. The percutaneous coronary intervention device comprises a device body, and a first catheter is installed at one end of the device body; a second catheter is installed at the end, away from the device body, of the first catheter, the outer wall of the second catheter is sleeved with a balloon, an inflation device is arranged on the inner wall of the balloon, and when the interior of the balloon needs to be inflated, a handle can be rotated, so that the balloon is inflated; an existing mode that an injector is pressed by a hand is changed into a mode that the control switch is rotated to control the gas entering content, the accuracy degree of the gas entering the balloon content is improved, and meanwhile distribution of operation time is optimized.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a percutaneous coronary intervention device for treating acute coronary syndrome. Background technique [0002] Acute coronary syndrome (ACS) is a group of clinical syndromes based on the rupture or invasion of coronary atherosclerotic plaque, secondary to complete or incomplete occlusive thrombosis, including acute ST-segment elevation myocardial infarction. , Acute non-ST-segment elevation myocardial infarction and unstable angina pectoris can generally be treated with drugs, surgery, percutaneous coronary intervention (PCI) and other treatments, among which percutaneous coronary intervention (PCI) When the femoral artery approach or radial artery approach is used, the guiding catheter is sent to the coronary ostium to be expanded, and then the balloon of the corresponding size is sent to the stenotic segment along the guide wire, and the appropriate pressure and time are used...
