Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a Y-type connector for coronary intervention surgery. Background Technology

[0002] In the field of coronary interventional surgery, balloon angioplasty is an important means of treating coronary artery stenosis or blockage. The functionality and ease of operation of surgical instruments directly affect the success rate of the surgery and the patient's prognosis.

[0003] In common coronary intervention procedures, it is often necessary to operate two sets of balloons and stents simultaneously. Doctors need to operate two pressure pumps to expand and contract the two sets of balloons. The operation requires two doctors. When it is necessary to apply the same pressure to the two sets of balloons or to expand and contract them synchronously, it is difficult for the two doctors to ensure the consistency of pressure and time. This can easily lead to uneven balloon expansion, affect the quality of angiogenesis, and may even cause complications such as vascular wall damage and dissection. Therefore, it is necessary to design a Y-type connector for coronary intervention procedures to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a Y-type connector for coronary intervention surgery to solve the problems mentioned in the background art.

[0006] The top surface of the rotating column is marked with two passage indicators that are in the same direction as the balloon tube. A shielding plate is fixedly installed at the upper end of the rotating column to cover the passage indicators. A limiting component for maintaining the angle of the rotating column is installed on the top surface of the shielding plate.

[0007] Preferably, the sealing assembly includes a mounting frame, a movable column is slidably mounted inside the mounting frame, a blocking block is fixedly mounted at one end of the movable column, a baffle is fixedly mounted at the other end of the movable column, and an elastic element is provided between the baffle and the mounting frame.

[0008] Preferably, the elastic element is a first spring, one end of which is fixedly installed on one side of the baffle, and the other end of which is fixedly installed on one side of the mounting bracket.

[0009] Preferably, the limiting component includes a swing plate, a rod is movably installed through the surface of the swing plate, a lifting plate is fixedly installed at the upper end of the rod, a second spring is connected between the lifting plate and the swing plate, and the limiting component also includes three insertion holes, the lower end of the rod is inserted into the insertion holes.

[0010] Preferably, the outer diameter of the insertion rod is appropriately matched with the inner diameter of the insertion hole.

[0011] Preferably, one end of the pressure pump connector is connected to a female Luer connector, and one end of the balloon connector is connected to a male Luer connector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This Y-type connector for coronary intervention surgery connects the female Luer connector to the pressure pump connector and the two male Luer connectors to the balloon connectors respectively. The pressure pump pushes the balloon in and out, and the two balloon connectors and male Luer connectors control the synchronous expansion or contraction of the two balloons, making it convenient for a single medical staff member to operate the two balloons simultaneously.

[0014] 2.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a Y-type connector for coronary intervention surgery, including a connecting post 1, a pressure pump connector 2 and two balloon connectors 3 connected to the outside of the connecting post 1, the three of which are distributed in a Y shape, a rotating post 6 is rotatably installed in the inner cavity of the connecting post 1, and an abutment head 7 is installed on the cylindrical surface of the rotating post 6 along the radial direction. A sealing component is installed inside the balloon connector 3 to close the balloon connector 3 after being abutted by the abutment head 7.

[0024] The top surface of the rotating column 6 is marked with two passage indicators 14 that are in the same direction as the balloon tube 3. A shielding plate 13 is fixedly installed on the upper end of the rotating column 6 to cover the passage indicators 14. A limiting component for maintaining the angle of the rotating column 6 is installed on the top surface of the shielding plate 13.

[0025] Specifically, two balloon connectors 3 are connected to the balloons and pushed by a pressure pump, thereby controlling the synchronous expansion or contraction of the two balloons through the two balloon connectors 3 and the Luer connector 5.

[0026] The sealing assembly includes a mounting frame 8, with a movable column 9 slidably mounted inside the mounting frame 8. A blocking block 12 is fixedly mounted at one end of the movable column 9, and a baffle 10 is fixedly mounted at the other end of the movable column 9. An elastic element is provided between the baffle 10 and the mounting frame 8. Specifically, the elastic element is a first spring 11. One end of the first spring 11 is fixedly mounted on one side of the baffle 10, and the other end of the first spring 11 is fixedly mounted on one side of the mounting frame 8. Rotating the rotating column 6 can drive the contact head 7 to rotate. During the rotation of the contact head 7, its curved surface can push the blocking block 12 on one side to block the balloon inlet 3 on that side.

[0027] The limiting component includes a swing plate 15, with a rod 16 movably mounted through its surface. A lifting plate 17 is fixedly mounted on the upper end of the rod 16. A second spring 18 connects the lifting plate 17 and the swing plate 15. The limiting component also includes three insertion holes 19. The lower end of the rod 16 is inserted into the insertion hole 19, and the outer diameter of the rod 16 is appropriately matched with the inner diameter of the insertion hole 19. Pulling up the lifting plate 17 causes the rod 16 to disengage from the middle insertion hole 19. At this time, rotating the lifting plate 17 drives the swing plate 15 and the shielding plate 13 through the rod 16. The rotating column 6 and the contact head 7 rotate synchronously. After the contact head 7 rotates to the appropriate position, the control lifting plate 17 drives the insertion rod 16 to be vertically inserted into the insertion hole 19, so that the angle position of the lifting plate 17, the contact head 7 and other components is fixed. When the insertion rod 16 is in the three insertion holes 19 respectively, it corresponds to the three states of the contact head 7 contacting the two blocking blocks 12 on both sides and not contacting any blocking block 12 on either side. This also corresponds to the three states of the balloon connecting pipe 3 on different sides being connected to the pressure pump connecting pipe 2 individually and the two balloon connecting pipes 3 being connected to the pressure pump connecting pipe 2 simultaneously.

[0028] Wherein: one end of the pressure pump connector 2 is connected to a female Luer connector 4, and one end of the balloon connector 3 is connected to a male Luer connector 5. The female Luer connector 4 and the male Luer connector 5 are used to connect the pressure pump and the balloon, respectively.

[0029] Working principle: This utility model is a Y-type connector for coronary intervention surgery. In use, the female Luer connector 4 is connected to the pressure pump connector, and the two male Luer connectors 5 are connected to the balloon connectors respectively. The pressure pump pushes the balloon, thereby controlling the synchronous expansion or contraction of the two balloons through the two balloon connectors 3 and the male Luer connectors 5, which makes it convenient for a single medical staff to operate the two balloons simultaneously.

[0030] If individual balloon control is required during the procedure, the lifting plate 17 is pulled up to disengage the insertion rod 16 from the central insertion hole 19. At this point, the lifting plate 17 is rotated, causing the insertion rod 16, the swing plate 15, the shielding plate 13, the rotating column 6, and the contact head 7 to rotate synchronously. During rotation, the contact head 7 pushes the side block 12 to block the balloon inlet 3 on that side. The shielding plate 13 rotates to block the indicator 14 on that side, thus sealing the individual balloon inlet 3. The insertion rod 16 is then inserted into the corresponding insertion hole 19, fixing the angle and position of the lifting plate 17. This fixes the angles of the insertion rod 16, swing plate 15, shielding plate 13, rotating column 6, and contact head 7, keeping the balloon inlet 3 closed on this side. This ensures that only the balloon inlet 3 on the other side is connected to the pressure pump inlet 2, facilitating the control of the expansion and contraction of a single balloon as needed. During this process, the shielding plate 13 covers the access indicator 14 corresponding to the closed balloon inlet 3, while the access indicator 14 on the open side can still be seen normally, allowing medical staff to check the orientation of the open and closed sides based on the access indicator 14 and avoid confusion.

[0031] Subsequently, when the contact head 7 no longer blocks the block 12, the first spring 11 can pull the baffle 10, the movable column 9 and the block 12 to reset, so that the balloon connector 3 on this side can be restored to the conductive state. Its conductive and closed state can be adjusted according to the needs of medical staff.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
