In particular, the balloon catheter of the present invention has an integrated shaft system and a balloon located near the distal end. The rod contains a dual lumen tubing. One lumen is used to inflate the balloon with a fluid such as saline or water, and the second allows a guidewire to pass through, as will be described in more detail below.
When the medical drainage device is used, the joint part 1 is connected with a mechanical part (not shown in the figure) for expanding the balloon, the balloon 2 is guided and pushed into the sinus ostium of a patient, fluid such as normal saline or water is filled into the balloon 2 through an external mechanical part to expand the balloon, the blocked part of the patient is propped open, so that the effect of smooth drainage is achieved, and operations such as disinfection, cleaning and the like can be applied. Relevant background work and the like reference may be made to CN 101563019a described in the background section, which is incorporated herein by reference in its entirety.
Fig. 2 shows an enlarged cross-sectional view at a in fig. 1, and as shown, the joint portion 1 includes a first joint portion 11 extending along the length of the balloon catheter, a second joint portion 12 perpendicular to the first joint portion 11, and a third joint portion 13 provided opposite to the first joint portion 11. The first joint part 11 communicates with a central tube 3 penetrating the third joint part 13, and the first joint part 11 and the center of the central tube 3 form a central hole 31 penetrating the entire balloon catheter. The second connector portion 12 communicates with a balloon inflation tube 4 penetrating the third connector portion 13; a balloon inflation tube 4 is placed around the outside of the central tube 3 and communicates with the balloon 2 (see fig. 4). The central bore 31 is sealed from the balloon 2 (see figure 4).
In operation, the first joint part 11 has a threaded connection 111, which allows for easy connection of other surgical components (e.g., a handle, etc.) (not shown); and the second joint part 12 also has a threaded connection 121 to which an external pipe (not shown) can be connected for inflating the balloon 2 by filling a fluid such as saline or water into the balloon inflation tube 4 through the external pipe by an external mechanical part. Since the first joint part 11 and the central tube 3 together form a central hole 31 penetrating through the whole balloon catheter, the luminous guide wire can be passed through the central hole 31 (see CN 101563019a, this prior art describes the luminous guide component in detail, and this is only used for describing the implementation process of the present invention, and the structure thereof is not described again at all). Moreover, since the central hole 31 and the balloon 2 are sealed with each other, the arrangement of the central hole 31 does not affect the inflation operation of the balloon 2. In addition, since the central hole 31 is provided in the center of the balloon 2, the entire balloon catheter is smooth on the outside, and no protruding parts may cause damage to the nasal cavity or sinus of the patient.
The first joint section 11 is a separate component having a tapered neck 112. Second joint section 12 and third joint section 13 are integrally injection molded, and neck 112 of first joint section 11 is inserted into the hole on the opposite side of third joint section 13 as shown and bonded by adhesive 32. The central tube 3 is inserted into the neck 112 and is bonded by means of an adhesive.
The third joint portion 13 also has a tapered neck opening 132, and the balloon inflation tube 4 is inserted and disposed in the neck opening 132; a metal support tube 5 is arranged outside the balloon inflation tube 4, and the metal support tube 5 partially extends into the neck opening 132. In the present invention, the balloon inflation tube 4 is also made of relatively soft plastic, and since it is long and has poor rigidity, a section of metal support tube 5 is provided outside it (see also fig. 3). In a specific embodiment of the present invention, the metal supporting tube 5 is provided for protecting the balloon inflation tube 4, and on the other hand, the portion of the metal supporting tube 5 exposed outside the neck opening 132 (see the portion of length L2 in fig. 1) also provides support for the balloon inflation tube 4, so as to avoid the balloon inflation tube 4 from being damaged by bending.
In order to facilitate the operator to understand the length of the balloon catheter being inserted into the nasal cavity during the operation, the outside of the portion of the metal support tube 5 exposed outside the neck opening 132 of the third joint part 13 (the portion of length L2 in fig. 1) is covered with a length recognition mark line 51, see fig. 5. These marking lines may be paint coated on the outside of the metal support tube 5, or colored plastic rings or the like stuck on the outside of the metal support tube 5.
Of course, in order to avoid the above-mentioned wear and tear of the identification mark line 51, in a preferred embodiment of the present invention, the entire outside of the metal support tube 5 (the portion of length L1 in fig. 1) is covered with a transparent protective film 6, see fig. 2 and 3. In fact, in this embodiment, the protective film 6 and the balloon inflation tube 4 may be thermally fused together, and the portion of the metal support tube 5 extending into the neck 132 of the third joint portion 13 is entirely wrapped by the protective film 6 and the balloon inflation tube 4, thereby isolating the metal support tube 5 from the fluid used to inflate the balloon 2. The metal supporting tube increases the propelling property and the rotatable type of the balloon catheter, and the protective film 6 can prevent the metal supporting tube from damaging a human body. On the other hand, because the metal support tube 5 is wholly wrapped by the protective film 6 and the balloon inflation tube 4, the metal support tube 5 is clamped very tightly and is not easy to rotate and loosen, and the structural firmness is improved.
In addition, in order to prevent the neck 132 of the third joint portion 13 from being loosely connected, a joint boot 7 is bonded to the outside of the neck 132.
Fig. 4 shows an enlarged cross-sectional view at C of fig. 1, in which the distal opening 41 of the balloon inflation tube 4 is bonded to the balloon 2, i.e., one end of the balloon 2 is bonded to the outside of the balloon inflation tube 4 and the other end is bonded to the outside of the central tube 3, and the middle portion of the balloon is inflated under pressure. The central tube 3 extends from the distal opening 41 of the balloon inflation tube 4 and extends through the entire balloon 2.
In order to inflate the balloon under pressure in practice, it is necessary to inject a fluid, such as physiological saline, into the balloon 2 through the balloon inflation tube 4 via the second joint portions 12, and to control the inflation of the balloon 2 by controlling the pressure of the injected fluid.
In addition, in order to be able to locate the position of the balloon 2 by means of X-rays during the operation, in a preferred embodiment, at least one radiopaque marking ring 33 is fixedly arranged on the outside of the portion of the central tube 3 inside the balloon 2, two radiopaque marking rings 33 are shown in fig. 4, respectively on both sides of the balloon 2, so as to locate the length position of the entire balloon 2, in a specific embodiment, the radiopaque marking rings 33 are platinum rings.
