All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide an impedance electrode catheter device installation method which can improve installation efficiency.

It is another core of the present invention to provide an impedance electrode catheter apparatus which is highly efficient in production.

Referring to fig. 1 to 7, fig. 1 is a flow chart illustrating a method for installing an electrode catheter device with impedance according to the present invention; FIG. 2 is a schematic diagram of a first embodiment of a resistance-elimination electrode catheter apparatus provided in the present invention; FIG. 3 is a partial cross-sectional view of a first embodiment of the present invention; FIG. 4 is a schematic diagram illustrating a state of a metal sheet disposing process according to an embodiment of the present invention; FIG. 5 is a schematic view of a second embodiment of a resistance electrode-rejecting catheter apparatus provided in accordance with the present invention; FIG. 6 is a partial cross-sectional view of a second embodiment of the present invention; fig. 7 is a schematic cross-sectional view of a second embodiment of the present invention.

The application provides an installation method of a catheter device with an impedance electrode, which specifically comprises the following steps:

and step S1, making a hole on the guide pipe, leading the conducting wire in the guide pipe out of the hole, and removing the insulating layer of the conducting wire extending out of the hole.

And step S2, selecting a metal sheet in a thin plate form and connecting the metal sheet to the lead with the insulation layer removed.

And step S3, bending the metal sheet and wrapping the metal sheet outside the guide pipe for fixing to form an impedance ring.

It should be noted that the catheter 1 in step S1 is a catheter 1 with a built-in lead wire 2, and a through hole may be provided on an outer tube body of the catheter 1, wherein the through hole refers to a single hole in the radial direction, and does not need to penetrate through the entire catheter in the radial direction, i.e., two holes do not need to be formed.

The conduit 1 is provided with a hole for leading out the wire 2 in the conduit 1, and the led-out portion can be subjected to insulation removal treatment, i.e., the insulation layer outside the wire 2 is removed, so that the conductive state is achieved.

In step S2, the metal sheet 3 is selected in the form of a thin plate in order to facilitate bending and wrapping around the outside of the catheter 1 in step S3, and the metal sheet 3 in the form of a thin plate facilitates bending and fixing processes. Before the bending and wrapping, the metal sheet 3 needs to be connected to the conductive portion of the lead 2 so as to be in a conductive state with the metal sheet 3.

In step S3, the metal sheet 3 connected to the lead wire 2 is bent and wrapped around the outside of the catheter 1, and a special device is required for wrapping and winding. When the wrapping is completed, the sheet 3 forms an impedance loop on the outside of the catheter 1.

Optionally, before the metal sheet 3 is wrapped on the catheter 1, a glue solution may be applied to the side of the metal sheet 3 to be attached to the catheter 1, so as to achieve a close attachment during the wrapping process.

The above-mentioned thin plate form is not limited to specific values of the thickness thereof, but means that it is a plate-like structure before the wrapping operation, and is not a ring-like plate, but forms a ring-like structure wrapped up on the catheter 1 in the circumferential direction by the wrapping operation.

According to the installation method of the impedance electrode conduit device, the conduit 1 is provided with the hole, so that the lead 2 is led out, the metal plate 3 of the thin plate structure is wrapped at the hole position of the conduit 1 on the basis, meanwhile, the electric connection with the lead 2 is realized, the metal plate 3 is in conductive connection with the lead 2 in a wrapping state, and the metal plate 3 can be used as an impedance ring. This mode of setting up is different from the mode with impedance ring lug connection in the middle of two pipes among the prior art, need not cut the pipe, operation such as connect, has avoided unnecessary operation flow, simultaneously because metal sheet 3 wraps up in pipe 1 outside, therefore its shape structure all sets up more easily, has better laminating characteristic with pipe 1. The installation method of the impedance electrode conduit device can simplify the installation mode of the impedance ring and improve the production efficiency of the impedance electrode conduit.

On the basis of the above embodiment, in step S3: bending and wrapping the metal sheet outside the conduit and fixing to form the impedance ring, which specifically comprises the following steps:

step S31, coating glue solution in the metal sheet along the winding direction, and wrapping the metal sheet at the impedance ring mounting position outside the guide pipe to form an impedance ring;

alternatively, step S32 is to wrap the metal sheet around the outer impedance ring mounting location of the conduit, and weld or crimp the conduit and the metal sheet to form the impedance ring.

The winding direction in the metal sheet 3 refers to the side of the metal sheet 3 that faces the catheter 1 during the wrapping operation, i.e., the side that is concave after bending. The coated glue solution is mainly used for bonding a metal structure, the glue solution is coated on the metal sheet 3 before the wrapping operation, and glue overflow needs to be prevented in the wrapping process.

An auxiliary fixing part can be arranged before the welding operation to fix the position relation of the metal sheet 3 and the guide pipe 1, so that the position deviation during the welding operation is avoided.

The impedance ring mounting place on the outside of the conduit 1 can be an annular recess on the outside of the conduit 1, or a straight pipe position where the impedance ring needs to be mounted is preset for the conduit 1. This position is a position where a hole of the catheter, that is, a hole for leading out the lead wire 2 is provided.

Alternatively, the impedance ring mounting location may be disposed adjacent to the location of the hole, but the hole and the lead 2 may be exposed, and an additional blocking and protecting structure may be required.

It should be noted that the metal sheet 3 is wrapped on the outer portion of the catheter 1 in various ways, not limited to the above-provided manner, and the metal sheet 3 may be provided with a corresponding connecting structure or a matching component based on other existing fixing manners.

On the basis of the above embodiment, after the glue solution is fixed, the glue is dispensed and reinforced to the end of the impedance ring and the joint position with the conduit.

Referring to fig. 1 to 3, the end portions of the impedance ring refer to two ends of the impedance ring forming a ring, the inner concave portion of the impedance ring is fixed by glue, but the end portions may have a position of being tilted or not sealed, so that the end portions are subjected to glue dispensing and sealing after the bonding is completed to achieve the effects of reinforcement and sealing, thereby ensuring the stability of the impedance ring.

Alternatively, if the metal sheet is welded or otherwise connected to the end of the impedance ring (i.e., the metal sheet 3), the impedance ring may be reinforced by using an adhesive or by performing a welding reinforcing operation.

On the basis of any of the above embodiments, in step S3: after the metal sheet is bent and wrapped outside the conduit and fixed, the method also comprises the following steps:

and step S33, sleeving a closed outer metal ring outside the impedance ring so that the outer metal ring completely wraps the metal sheet, closing the end part of the outer metal ring, and applying glue and sealing the two ends of the outer metal ring to form the impedance ring.

Referring to fig. 4 to 6, an outer metal ring 31 may be further disposed outside the metal sheet 3, and the outer metal ring 31 needs to completely wrap the metal sheet 3 and achieve the effect of enhancing the stability of the metal sheet 3. The port closing arrangement of the outer metal ring aims to avoid the problem of burrs and warping at the transition of the catheter 1 and the metal sheet 3, so as to enhance the use safety.

It should be noted that, in this embodiment, the inner metal sheet 3 may be a structure that is not sealed in the circumferential direction, and the outer portion of the inner metal sheet is to be attached to the outer metal ring 31, so that the metal sheet 3 may not be sealed when wrapped, thereby avoiding increasing the difficulty of processing. The outer metal ring 31 needs to be a closed structure, completely wrapping the metal sheet 3 in the circumferential direction.

In any of the above embodiments, the sheet metal in sheet form may be a rectangular flat sheet prior to the wrapping operation. That is, the rectangular metal sheet 3 can be selected and used, and the neatness of the wrapping operation can be easily ensured in the processing process
