Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a medical guide wire fixing device. Background Art

[0002] In percutaneous coronary intervention (PCI), coronary guidewires are key tools for precise placement of intravascular devices such as catheters, stents, and balloons. The procedure usually involves puncturing a peripheral artery and inserting a sheath, introducing a guide catheter through the sheath to the narrowed coronary artery, and then using the guidewire to guide the balloon catheter to the lesion site for expansion, or to guide the stent to the appropriate position to restore vascular patency. However, there are obvious problems with the fixation of the guidewire during existing surgeries. When the balloon or stent passes through the Y-valve in and out, there is a lack of effective fixation measures, which can easily lead to the branch guidewire being brought out, increasing the risk of surgical complications. In addition, due to the variety of guidewire models on the market, including guidewires of different hardness and diameters, as well as guidewires of varying lengths, the management of guidewires during surgery is more complicated.

[0003] In cases involving complex lesions that require simultaneous expansion or protection of multiple blood vessels, the use of multiple guidewires can easily lead to entanglement and knotting between them, which not only affects the smooth entry of the balloon, but also brings additional challenges to the operation. Although countermeasures such as assistant-assisted pressing or gauze fixation have been adopted in clinical practice, these methods have limitations. The assistant's pressing on the guidewire limits the freedom of his hands and affects the progress of other surgical operations; and the effect of gauze fixing the guidewire is limited, and it is difficult to maintain the stability of the guidewire when the balloon enters and exits, which increases the risk of guidewire sliding or displacement, which may cause serious complications such as coronary artery perforation. Therefore, the problem of guidewire fixation in existing surgeries needs to be improved urgently to improve the safety and success rate of the operation. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a medical guide wire fixing device to conveniently and firmly fix the guide wire, thereby significantly improving the efficiency and safety of interventional surgery.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] The utility model discloses a medical guide wire fixing device, which is characterized by comprising a clip, a base and an attachment fixing structure; the clip is arranged on the top surface of the base in an upright manner, and the clip has a V-shaped groove extending downward from the upper edge to the adjacent lower edge; and the attachment fixing structure is arranged on the bottom surface of the base.

[0007] The V-shaped groove is composed of a deep V-shaped groove at the bottom and a shallow V-shaped groove at the top, or is composed of a deep V-shaped groove at the bottom, a medium V-shaped groove at the middle and a shallow V-shaped groove at the top.

[0008] At least one pair of positioning arcs are arranged on the two side edges of the lower part of the deep V-shaped groove, and the shape of each pair of positioning arcs is adapted to the outer contour of the guide wire.

[0009] The clip and the base are an integral structure.

[0010] The clip and the base are of a plug-in split structure, a tenon is arranged on the lower edge of the clip, and a groove matched with the tenon is arranged on the top surface of the base.

[0011] The beneficial effects of the utility model are mainly reflected in the following aspects:

[0012] During interventional surgery, the guide wire can be effectively fixed, freeing the surgeon's hands to perform other operations, which not only improves surgical efficiency but also helps save precious medical resources.

[0013] When faced with complex interventional surgeries that require multiple guidewires, multiple fixtures can be combined to conveniently manage each guidewire. Each fixture is equipped with a corresponding label, which helps doctors clearly identify the ownership of each guidewire, avoiding additional surgical operations caused by confusion, thereby effectively reducing surgical time;

[0014] The clip is made of elastic material. When the guide wire is inserted, it can be stably fixed in the V-shaped groove without causing damage to the guide wire.

[0015] An attachment and fixing structure is provided at the bottom, which can be firmly attached and fixed to the side of the operating bed or bed sheet, so that the positions of multiple guide wires outside the body are effectively fixed, greatly reducing the possibility of entanglement between the guide wires, further simplifying the surgical process and improving surgical efficiency.
