Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a contrast-enhancing surgical device. Background Technology

[0002] Since the introduction of minimally invasive treatment techniques in the medical field in the 1990s, especially in the treatment of cardiovascular diseases, interventional minimally invasive therapy has become the preferred treatment method. Interventional minimally invasive therapy refers to surgical treatment performed by making an incision in a part of the patient's body with the aid of X-rays and medical imaging technology, and then using interventional instruments to reach the lesion site. In cardiovascular interventional therapy, a catheter is essential to establish a pathway for the interventional instrument to reach the lesion and place it, or to perform surgical procedures using the instrument. Determining whether the interventional instrument has accurately reached the patient's lesion or the required position during the procedure is a prerequisite for a successful operation. Therefore, cardiovascular interventional catheters must be visualized within the body with the help of metal rings or plates that are not penetrated by X-rays.

[0003] Existing interventional devices typically fall into the following two categories:

[0004] One type of interventional catheter consists of an inner liner, a metal braided layer, and an outer tubing layer. The inner liner and outer tubing layers are made of polymer materials. When these three layers are combined, a metal radiopaque ring is added and sandwiched between the inner liner and the outer tubing layer. However, this type of interventional device is inconvenient to manufacture, and this method of device creation is not applicable to some interventional catheters, such as some catheters that do not have an inner liner or metal braided layer and only have an outer tubing layer (such as central venous catheters and biliary drainage tubes). Because these tubes do not have a heat sealing process during manufacturing, it is impossible to sandwich the metal radiopaque ring in the tube body.

[0005] Another option is to fit a metal contrast ring onto the tube body. However, since some interventional catheters are very soft, directly squeezing and fixing the metal contrast ring onto the tube body would reduce the inner diameter of the tube body. Therefore, the contrast ring cannot be squeezed onto the tube body.

[0006] Furthermore, regardless of the type of interventional device used, a metal imaging ring is required. However, the metals that can be used as imaging rings are generally precious metals, such as platinum-iridium, which is expensive. Utility Model Content

[0007] This invention addresses the problems of existing technologies by providing a contrast-enhancing device that prevents the contrast ring from squeezing the interventional catheter and can fix the contrast ring to the interventional catheter body, so that the contrast ring does not affect the use of the interventional catheter. It is applicable to contrast-enhancing surgical devices for various types of interventional catheters.

[0008] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0009] A contrast-enhancing surgical device includes a tube body, a contrast ring, and an adhesive coating layer. The contrast ring is disposed on the tube body, and the adhesive coating layer covers and fixes the contrast ring to the tube body.

[0010] Preferably, the developing ring has a double-coating structure, including an adhesive coating and a metal coating. The adhesive coating is applied around the outer wall of the tube body, and the metal coating is sprayed onto the adhesive coating.

[0011] Preferably, the adhesive layer covers the outside of the metal coating.

[0012] Preferably, the adhesive coating is a light-curing adhesive coating, and the metal coating is a tungsten powder coating.

[0013] Preferably, the developing ring is a metal ring, which is sleeved on the tube body, and the inner diameter of the metal ring is larger than the outer diameter of the tube body.

[0014] Preferably, the adhesive layer covers the outside of the metal ring and fixes the metal ring to the tube body.

[0015] Preferably, the metal ring material is one of osmium, iridium, platinum, tungsten, gold, tantalum, or platinum-iridium alloy.

[0016] Preferably, the adhesive layer is a light-curing adhesive.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) By coating the imaging ring with an adhesive layer, the imaging ring can be firmly fixed to the tube body without the need for an additional connecting device, thus preventing the imaging ring from squeezing the interventional catheter and ensuring that the imaging ring does not affect the use of the interventional catheter. This invention is applicable to various types of interventional catheters.

[0019] (2) This utility model applies an adhesive coating around the outer wall of the tube body and then sprays a tungsten powder coating onto the adhesive coating, so that the setting of the imaging ring is not limited by the material and structure of the tube body. It is suitable for various types of interventional catheters, is easy to manufacture, and will not squeeze the tube body of the interventional catheter, will not reduce the inner diameter of the interventional catheter, and will not affect the use of the interventional catheter. Furthermore, by replacing the imaging metal ring with the adhesive coating and tungsten powder coating, the use of precious metals is reduced, and the manufacturing cost is lowered.

[0020] (3) By setting the imaging ring to a metal ring and setting the inner diameter of the metal ring to be larger than the outer diameter of the tube body, a gap is left between the metal ring and the tube body, which can prevent the metal ring from squeezing the tube body and ensure that the use of the interventional catheter is not affected by the setting of the imaging ring; at the same time, the metal ring is coated with an adhesive layer on the outside, so that the metal ring can be fixed on the tube body, which enhances the firmness of the imaging ring and prevents the metal ring from falling off easily due to the inner diameter of the metal ring being larger than the outer diameter of the tube body, thus reducing the risk of the imaging ring falling off.

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.

[0026] In the description of this utility model, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "side", "top", "inner", "front", "center", "both ends", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example 1

[0029] Combination Figure 1-2 As shown, this utility model embodiment provides a contrast-enhancing surgical device, including a tube body 1, a contrast-enhancing ring 2, and a coating layer 3. The contrast-enhancing ring 2 is disposed on the tube body 1, and the coating layer 3 covers the contrast-enhancing ring 2 and fixes the contrast-enhancing ring 2 on the tube body 1.

[0030] Preferably, the adhesive layer 3 is a light-curing adhesive;

[0031] By coating the imaging ring 2 with the adhesive layer 3, the imaging ring 2 can be firmly fixed to the tube body 1 without the need for an additional connecting device. This prevents the imaging ring 2 from squeezing the interventional catheter and ensures that the imaging ring 2 does not affect the use of the interventional catheter. This method is applicable to various types of interventional catheters.

[0032] Example 2

[0033] Based on Example 1, the developing ring is specifically configured as follows: In this example, the developing ring 2 has a double-coating structure. Specifically, the developing ring with the double-coating structure can be a regular ring or an irregular ring, as long as it can realize the developing function of the developing device. The double-coating structure includes an adhesive coating and a metal coating. The adhesive coating is applied around the outer wall of the tube body 1, and the metal coating is sprayed onto the adhesive coating. The adhesive layer 3 covers the outside of the metal coating. Specifically, the adhesive coating is a light-cured adhesive coating, and the metal coating is a tungsten powder coating.

[0034] In practical applications, since tungsten powder and photocurable adhesive do not react chemically, they can be mixed evenly. For example, 60-70 parts of photocurable adhesive and 30-40 parts of tungsten powder can be thoroughly mixed in a dim environment to prevent tungsten powder from settling and photocurable adhesive from curing. Then, the photocurable adhesive mixed with tungsten powder is applied around the outer wall of the tube body, and then a coating layer is applied over the photocurable adhesive mixed with tungsten powder. Alternatively, photocurable adhesive can be applied to enhance the adhesion of the photocurable adhesive mixed with tungsten powder, i.e., the developing ring.

[0035] By applying an adhesive coating around the outer wall of the catheter body and then spraying a tungsten powder coating onto the adhesive coating, the placement of the imaging ring is not limited by the material and structure of the catheter body. This makes it suitable for various types of interventional catheters, facilitates manufacturing, and does not compress the catheter body or reduce the inner diameter of the interventional catheter, thus not affecting its use. Furthermore, by using the adhesive coating and tungsten powder coating instead of the imaging metal ring, the use of precious metals is reduced, lowering manufacturing costs.

[0036] Example 3

[0037] Based on Example 1, the developing ring 2 is specifically configured as follows: In this example, the developing ring 2 is a metal ring, which is sleeved on the tube body 1. There is a certain gap between the metal ring and the tube body 1. Specifically, the gap size can be 0.01mm-0.05mm. The inner diameter of the metal ring is larger than the outer diameter of the tube body 1. For example, if the outer diameter of the tube body 1 is 2mm, the inner diameter of the metal ring is set to 2.01mm-2.05mm. The adhesive layer 3 covers the outside of the metal ring and fixes the metal ring on the tube body 1.

[0038] Preferably, the metal ring material is one of osmium, iridium, platinum, tungsten, gold, tantalum, and platinum-iridium alloy;

[0039] By setting the imaging ring 2 to a metal ring, and setting the inner diameter of the metal ring to be larger than the outer diameter of the tube body 1, a gap is left between the metal ring and the tube body 1, thereby preventing the metal ring from squeezing the tube body 1 and ensuring that the use of the interventional catheter is not affected by the setting of the imaging ring 2. At the same time, the metal ring is coated with an adhesive layer 3, which allows the metal ring to be fixed to the tube body 1, enhancing the firmness of the imaging ring 2 and preventing the metal ring from easily falling off due to the inner diameter of the metal ring being larger than the outer diameter of the tube body 1, thus reducing the risk of the imaging ring 2 falling off.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the scope of this utility model application should be included within the protection scope of this utility model.
