Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a coronary intervention guidewire fixation patch and its method of use. Background Technology

[0002] In coronary interventional procedures, multiple guidewires are often inserted into different branches of the coronary arteries via the same guiding catheter to treat complex lesions. Proper management of the guidewire ends at the catheter tip is crucial to prevent dislodgement, slippage, or entanglement, thus ensuring the smooth progress of the procedure and patient safety. Currently, various fixation methods exist for the guidewire ends, such as using specialized fixation platforms with clips or locking mechanisms. These existing technologies achieve the goal of guidewire fixation to a certain extent.

[0003] However, existing guidewire fixation devices generally suffer from complex structures and cumbersome operation procedures. They typically consist of a separate fixation base and movable clips, which not only occupy already limited operating table space, affecting the placement of other instruments and the surgeon's operation, but also require two-handed alignment and clamping actions during use, increasing surgical preparation time and operational complexity. In interventional surgeries where every second counts, cumbersome fixation procedures can waste valuable surgical time and may even lead to guidewire displacement due to untimely fixation or operational errors, indirectly affecting surgical efficiency and safety.

[0004] Therefore, how to develop a coronary intervention guidewire fixation patch that can achieve rapid, single-handed, and reliable fixation and release of the guidewire tail without occupying additional table space, thereby effectively simplifying the surgical procedure and preventing guidewire entanglement and dislodgement, has become a technical problem that urgently needs to be solved by those in the field. Summary of the Invention

[0005] The purpose of this invention is to provide a coronary intervention guidewire fixation patch and its usage method, which can achieve quick, single-handed, and reliable fixation and release of the guidewire tail without occupying additional table space, thereby effectively simplifying the surgical procedure and preventing guidewire entanglement and dislodgement.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a coronary intervention guidewire fixation patch, comprising a patch body, wherein the bottom surface of the patch body is provided with an adhesive layer, and the top surface of the patch body is provided with at least two slots for holding the tail end of the guidewire.

[0007] Preferably, the top surface of the patch body is integrally formed with multiple protrusions, and the slot is a through groove structure formed on the top of the protrusions.

[0008] Preferably, the opening width of the slot is smaller than the outer diameter of the guide wire.

[0009] Preferably, the number of the protrusions is set to four, and they are arranged at intervals along the length of the patch body.

[0010] Preferably, the patch body and the protrusion are integrally molded from medical plastic.

[0011] Preferably, it also includes a peel protection layer covering the adhesive layer.

[0012] A method for using a coronary intervention guidewire fixation patch includes the following steps: S1. Select a fixation patch with a corresponding number of slots based on the number of guidewires to be used through the same guiding catheter; remove the peel-off protective layer on the adhesive layer, and attach the fixation patch to the operating table through the adhesive layer; S2. In coronary intervention surgery, when multiple guidewires are inserted through the same guiding catheter, the tail end of the non-operational guidewire that is not currently being operated on is laterally pressed into and held in the slot. S3. When it is necessary to operate on a certain non-operational guidewire, its tail end is removed laterally from the corresponding slot.

[0013] Preferably, in step S2, the tail ends of the multiple non-operational guidewires are respectively held in different slots.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows: 1) This invention eliminates the need for a separate fixing base and complex buckles through a minimalist patch design. When in use, you only need to press the end of the guidewire downward into the slot or take it out upward with one hand to complete the fixing or release. The entire operation can be completed instantly without taking your eyes off the surgical field or using both hands. This significantly simplifies the operation process, shortens the time required for guidewire management during the operation, and helps to improve the overall efficiency of the operation. 2) This invention is directly attached to the operating table. It is thin and occupies a small area, hardly taking up any valuable operating space on the table. It will not interfere with the placement of other surgical instruments or the surgeon's operating space, making the operating table layout neater and more orderly. 3) This invention effectively prevents the guidewire from slipping or shifting during surgery by reliably holding the guidewire tail end with a slot; at the same time, the use of multiple slots arranged at intervals to physically isolate multiple guidewires fundamentally avoids the risk of guidewires getting tangled together. This reduces operational errors or surgical interruptions caused by improper guidewire management, and also improves the safety and controllability of the surgical process, which is especially beneficial for the smooth implementation of complex multi-guidewire surgeries.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0019] like Figure 1-5 As shown, it includes a patch body 1, the bottom surface of the patch body 1 is provided with an adhesive layer 2, and the top surface of the patch body 1 is provided with at least two slots 3 for holding the tail end of the guide wire 5.

[0020] Specifically, this invention provides a minimally simplistic fixation patch, the core of which is a directly attachable patch body 1, achieving rapid fixation through an adhesive layer 2 on the bottom surface. The top surface of the patch body 1 is designed with at least two slots 3 specifically for temporarily holding the tail end of the guidewire 5 during coronary intervention surgery. This design eliminates the need for a complex fixation platform and locking mechanism, fundamentally solving the problems of existing technologies occupying operating table space and being cumbersome to operate. During use, simply press the non-operating guidewire tail end into the slot 3 to complete the fixation; it can be removed when needed, requiring no special training and greatly facilitating surgical procedures.

[0021] Specifically, the top surface of the patch body 1 is integrally formed with multiple protrusions 4, and the slot 3 is a through groove structure formed on the top of the protrusions 4.

[0022] Specifically, in this embodiment, the slot 3 is formed as follows: multiple protrusions 4 are integrally formed on the top surface of the patch body 1, and a through groove is vertically opened at the center of the top of each protrusion 4 to form the slot 3, so that the front of the protrusion 4 has a "U" shaped structure. This structure allows the guidewire 5 to be pressed vertically into the slot 3 from above or removed vertically upward, making the operation direct and effortless. The design of the protrusions 4 raises the holding point, allowing the tail of the guidewire 5 to be lifted off the table surface, further avoiding mutual contact and entanglement between guidewires, and also providing the operator's fingers with a clearer operating space.

[0023] Specifically, the opening width of the slot 3 is smaller than the outer diameter of the guide wire 5.

[0024] Specifically, this embodiment defines the key dimensions of the slot 3. The opening width of the slot 3 is designed to be slightly smaller than the outer diameter of the standard coronary intervention guidewire 5. This dimensional fit means that when the guidewire 5 is pressed into the slot 3, it needs to be slightly squeezed through the narrow opening. Relying on the slight elastic deformation of the medical plastic material, the guidewire 5 is firmly restricted in the slot 3, effectively preventing it from accidentally dislodging during the operation due to traction or unintentional contact, thereby ensuring the reliability of the fixation.

[0025] Specifically, the number of the protrusions 4 is set to four, and they are arranged at intervals along the length direction of the patch body 1.

[0026] Specifically, this quantity is sufficient for most coronary interventional procedures requiring dual or even multiple guidewires. The spaced arrangement of the four slots 3 ensures that the ends of multiple guidewires 5 maintain a safe distance when fixed, achieving physical isolation, which is crucial to preventing multiple guidewires from becoming entangled. At the same time, the neat arrangement also ensures that items on the operating table are placed in an orderly manner.

[0027] Specifically, the patch body 1 and the protrusion 4 are integrally molded from medical plastic.

[0028] Specifically, both the patch body 1 and the protrusion 4 are manufactured from medical-grade plastic that meets medical safety standards using a one-piece molding process. This one-piece molding ensures a robust structure with no seams, facilitates cleaning and disinfection, and avoids the potential risk of small parts falling off. The choice of medical-grade plastic guarantees the product's biocompatibility and safety in the surgical environment. This manufacturing method also simplifies the product structure, making it suitable for large-scale, low-cost production.

[0029] Specifically, it also includes a peel protection layer covering the adhesive layer 2.

[0030] Specifically, the peel-off protective layer effectively keeps the adhesive layer 2 clean and sticky before use, preventing it from being contaminated or having foreign objects adhering to it prematurely. During the surgical preparation stage, the surgeon only needs to peel off the peel-off protective layer to expose the clean adhesive layer 2 for application, further improving the convenience and reliability of use.

[0031] A method for using a coronary intervention guidewire fixation patch includes the following steps: S1. Based on the number of guidewires 5 to be used through the same guiding catheter, select a fixing patch with a corresponding number of slots 3; remove the peel-off protective layer on the adhesive layer 2, and attach the fixing patch to the operating table through the adhesive layer 2; S2. In coronary intervention surgery, when multiple guidewires 5 are inserted through the same guiding catheter, the tail end of the non-operational guidewire that is not currently being operated on is laterally pressed into and held in the slot 3. S3. When it is necessary to operate on a certain non-operational guidewire, its tail end is taken out laterally from the corresponding slot 3.

[0032] Specifically, this embodiment illustrates the method of using the fixation patch in actual coronary intervention surgery. The core logic of this method is "instant placement and fixation, instant removal and use." During the procedure, the surgeon can, at any time, insert the non-operational guidewire end into the slot 3 of the patch, instantly fixing it to the operating table and effectively preventing slippage, depending on the guidewire's usage status. When operation is required, it can be immediately removed to restore control. The entire process can be completed in one second with one hand, without the need for visual shifting or auxiliary tools, greatly optimizing the surgical procedure and reducing operational interruptions or risks caused by improper guidewire management. It is suitable for treating complex lesions requiring rapid guidewire switching.

[0033] Specifically, in step S2, the tail ends of the multiple non-operational guidewires are respectively held in different slots 3.

[0034] Specifically, this embodiment further refines the optimal operating method in the case of multiple guidewires. In step S2, when multiple non-operating guidewires need to be fixed simultaneously, the principle of "one slot, one line" should be followed, and each guidewire should be inserted into an independent slot 3. This approach utilizes the structural layout of the patch itself to completely isolate the tail ends of each guidewire in physical space, fundamentally eliminating the possibility of them tangling together.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
