Description

Technical Field

[0001] The utility model belongs to the technical field of neuroguide wire processing, and more specifically, relates to a hydrophilic dipping device for a neurointerventional guide wire. Background Art

[0002] Neurointerventional guide wires, such as nitinol wires, need to gently shuttle through blood vessels and the digestive tract without damaging tissues. Nitinol guide wires are used in the treatment of blood vessels around the heart, carotid arteries, cerebral blood vessels, and digestive systems, etc.; mainly for treating diseases such as angina pectoris and myocardial infarction caused by blockage or stenosis of blood vessels (coronary arteries) around the heart due to excessive cholesterol; and nitinol wires have low hardness, high flexibility, are not easily deformed, and have good biocompatibility.

[0003] The surface of the neurointerventional guide wire needs to be coated with a hydrophilic coating, so that the surface of the guide wire is covered with a hydrophilic coating. When encountering liquid, a smooth gel is formed on its surface, increasing lubricity and reducing friction, making the guide wire very lubricated and able to pass through narrow parts well.

[0004] Currently, for the dipping device of the hydrophilic coating of the guide wire, the adopted method is: taking the clamping part that clamps the guide wire as the moving part, so that the surface of the guide wire is covered with a hydrophilic coating. The disadvantage of this method is that the movement stability coefficient of such a guide wire clamping part is not high, and coupled with the mixed use of the hydrophilic coating, it is easy to cause poor phenomena such as sagging or accumulation of the hydrophilic coating on the surface of the guide wire.

[0025] A clamping part, arranged above the substrate 1, for clamping the end of the neurointerventional guide wire; that is, both ends of the neurointerventional guide wire are respectively connected to a clamping part;

[0026] A dipping part, movably connected to the substrate 1; the neurointerventional guide wire cooperates with the dipping part.

[0027] Specifically, in this embodiment, the clamping part includes a fixing plate 5 arranged above the substrate 1, and a plurality of clips 6 for clamping the neurointerventional guide wire are arranged on the fixing plate 5. It should be noted that the function of the clip 6 is to clamp the neurointerventional guide wire, and its structure is the prior art and will not be elaborated here.

[0028] Further, in this embodiment, as Figure 1 shown, it further includes a first lifting part. The clamping part is connected to the substrate 1 through the first lifting part, so that the clamping part can rise or fall relative to the substrate 1; the first lifting part includes a first lead screw 4, and the first lead screw 4 is threadedly connected to the fixing plate 5; the first lead screw 4 is connected to the free end of a first power part 8 arranged on the substrate 1. It should be noted that the first power part 8 is a motor, which is the prior art and will not be elaborated here; when the first power part 8 works, it drives the first lead screw 4 to rotate forward or backward, so as to realize the rising or falling of the fixing plate 5 cooperating with the first lead screw 4 relative to the substrate 1. It should be noted that the fixing plate 5 and the substrate 1 are cooperated through a slide rail and a slider to make the rising or falling process more stable.

[0029] Further, in this embodiment, as Figure 1 shown, it further includes a height limiting piece 9, and the height limiting piece 9 is connected to the top of the first lead screw 4 for limiting the fixing plate 5.

[0030] Further, in this embodiment, as Figure 1As shown in the figure, the dip coating part includes a number of dip coating hoses 2 movably arranged on the base body 1 at intervals. A connecting part for connecting the dip coating hoses 2 is provided on the base body 1, so that the dip coating hoses 2 can move on the connecting part; the number of connecting parts corresponds to the number of dip coating hoses 2 one by one; a neurointerventional guide wire is threaded through the dip coating hoses 2, and both ends of the neurointerventional guide wire are respectively connected to the clips 6 on the corresponding clamping parts; the connecting part is a connecting groove, and its inner wall is coated with lubricating oil to enable the dip coating hoses 2 to run smoothly therein; during use, the dip coating hoses 2 are filled with a hydrophilic dip coating solution;

[0031] In order to prevent the neurointerventional guide wire from being pulled and broken at both ends of the dip coating hose 2, a guiding part 21 is formed at the end of each dip coating hose 2. The guiding part 21 is in a trumpet shape, and its trumpet opening faces outward;

[0032] The dip coating part further includes a second lifting part. The second lifting part is connected to the base body 1, and the second lifting part drives the dip coating hoses 2 to move on the connecting part of the base body 1; the second lifting part includes a second lead screw 3, and the second lead screw 3 is connected to the free end of a second power part 7 provided on the base body 1; the ends of a number of dip coating hoses 2 are threadedly connected to the corresponding second lead screw 3 on the corresponding side through a connecting piece 22; as an example, the connecting piece 22 is connected to the guiding part 21; it should be noted that the second power part 7 is a motor, which is a prior art and will not be elaborated here; when the second power part 7 works, it drives the connecting piece 22 to rise or fall on the second lead screw 3, and further drives the dip coating hoses 2 to move on the connecting part of the base body 1, so that the neurointerventional guide wire does not produce sagging or accumulation phenomena during the dip coating process.

[0033] During operation, first, ensure that there is sufficient hydrophilic dip coating solution inside the dip coating hoses 2. When dip coating the neurointerventional guide wire, the first lifting part can basically remain stationary. Just firmly install the neurointerventional guide wire on the clamping part. Subsequently, the second power part in the second lifting part can be started to control the dip coating work of the dip coating hoses 2. The dip coating hoses 2 move smoothly upward following the rotation of the second lead screw 3, slowly leave and rise from the connecting part in the base body 1. After ensuring that the neurointerventional guide wire is accurately immersed in the dip coating hoses 2, after standing and immersing for a preset time, the dip coating hoses 2 descend and return to the base body 1 to complete the dip coating.

[0034] When facing an extremely long neurointerventional guide wire, the first lead screw can be replaced with a lengthened one, and the fixed plate can also move longitudinally to complete the dip coating work.
