The main function of a surgical guidewire is to guide surgical instruments to the target area, establish a surgical channel, and help doctors perform surgical operations. In vascular interventional surgery, a surgical guidewire is usually used to guide the catheter into the blood vessel and help the doctor place the catheter in the correct position, making it easier for the doctor to apply medication and treatment to the treatment area.

[0003] Patent document CN215083997U discloses a guidewire for a bifurcated blood vessel, which discloses that "the guidewire for a bifurcated blood vessel is used to guide a catheter through a bifurcated position of a bifurcated blood vessel. The guidewire for a bifurcated blood vessel includes a guidewire body, an elastic entity and two developing structures; the elastic entity is shuttle-shaped, the elastic entity is fixedly arranged at the front end of the guidewire body, and the guidewire body is located at the center of the elastic entity, the catheter is passed through the guidewire body and can be slidably mounted on the elastic entity, and the two developing structures are respectively fixedly arranged at both ends of the elastic entity. The guidewire for a bifurcated blood vessel can keep the catheter concentric with the guidewire body, can effectively prevent the catheter from scratching the bifurcated position of the blood vessel, and at the same time improve the passing efficiency of the catheter through the bifurcated position of the blood vessel, and has a simple structure and is easy to operate."

[0004] However, the guidewire for bifurcated blood vessels disclosed in the above-mentioned public document mainly considers the passing efficiency of the high-speed catheter through the bifurcated position of the blood vessel, has a simple structure, and is easy to operate, but is not convenient for timely stopping bleeding at the site inside the patient's blood vessel. Because the existing catheter body and guidewire body do not quickly stop bleeding at the bleeding site in the blood vessel, the scope of application of the surgical guidewire is reduced.

[0005] In view of this, it is necessary to develop a hemostatic mechanism so that the bleeding inside the patient's blood vessels can be stopped in time. Utility Model Content

[0006] The purpose of the utility model is to provide a guide wire for vascular intervention surgery, so as to solve the technical problem proposed in the above background technology that the guide wire for vascular intervention surgery has a hemostatic function.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is equipped with a hemostatic mechanism to stop bleeding in time at the site where the bleeding occurs inside the patient's blood vessel. The existing catheter body and guide wire body do not stop bleeding quickly at the bleeding site in the blood vessel, which reduces the scope of application of the surgical guide wire. Therefore, it is necessary to improve this so that the surgical guide wire has a hemostatic function and can quickly stop bleeding at the bleeding site inside the blood vessel, thereby enhancing its scope of application. When bleeding occurs in the blood vessel, after the catheter body moves to the site that needs to be treated, the inflation tube is inflated through the external inflation end, and then the inflated hemostatic balloon swells to drive the hemostatic block to move, and the hemostatic block is used to press the bleeding site in the blood vessel to stop bleeding, and the blood stains are adsorbed by the hemostatic layer. The smooth layer allows the catheter body to move smoothly to the treatment site, so that the catheter body has a hemostatic function, avoiding the situation where bleeding cannot be stopped immediately due to bleeding in the blood vessel.

[0017] 2. The utility model is equipped with a lighting mechanism to illuminate the wound inside the patient's blood vessel, which is convenient for medical staff to view. The existing moving route of the guide wire body is viewed through external infrared equipment. When the existing catheter body moves to the place where treatment is required, the light in the blood vessel is dim, which causes the medical staff to be unable to see the situation at the treatment site more clearly. Therefore, it is necessary to illuminate the treatment site after the catheter body moves to the treatment position, so that the medical staff can observe the situation at any time. When the catheter body moves to the place where treatment is required, the battery box is powered on according to the needs of the medical staff, and then the lighting lamp illuminates the treatment site, which is convenient for the staff to view on the infrared equipment. The protective glass cover is used to protect the lighting lamp, and the inclined plate prevents the drug from remaining on the supporting table, so that the catheter body has lighting work, which is convenient for medical staff to view the treatment site.

[0028] See also Figure 3 and Figure 4The outer wall of the catheter body 1 is provided with a hemostatic mechanism, which is used to stop bleeding in time at the site where the patient's blood vessel appears. The hemostatic mechanism includes a hemostatic groove 5, which is arranged on the outer wall of the catheter body 1. The inner wall of the hemostatic groove 5 is installed with a fixed block 6, and the outer wall of the fixed block 6 is installed with an inflatable hemostatic balloon 7. The outer wall of the inflatable hemostatic balloon 7 is provided with an inflatable tube 8. The outer wall of the inflatable hemostatic balloon 7 is installed with a hemostatic block 9, and the outer wall of the hemostatic block 9 is inlaid with a hemostatic layer 10. The outer wall of the hemostatic block 9 is provided with a smooth layer 11. The existing catheter body 1 and the guide wire body 2 do not quickly stop bleeding at the bleeding site in the blood vessel, but reduce the application scope of the surgical guide wire, so it is necessary to Improvements should be made to this so that the surgical guide wire has a hemostatic function and can quickly stop bleeding at the bleeding site inside the blood vessel, thereby expanding its scope of application. When bleeding occurs in the blood vessel, after the catheter body 1 is moved to the position that needs treatment, the inflation tube 8 is inflated through the external inflation end, and then the inflated hemostatic balloon 7 is inflated to drive the hemostatic block 9 to move. The hemostatic block 9 is used to press the bleeding site in the blood vessel to stop bleeding, and the blood stains are adsorbed by the hemostatic layer 10. The smooth layer 11 allows the catheter body 1 to move smoothly to the treatment site, so that the catheter body 1 has a hemostatic function to avoid the situation where bleeding cannot be stopped immediately due to bleeding in the blood vessel.

[0029] See also Figure 1 and Figure 5 The inner wall of the catheter body 1 is provided with a lighting mechanism, which is used to illuminate the wound inside the patient's blood vessel, so that the medical staff can watch it. The lighting mechanism includes a support platform 12, which is arranged inside the catheter body 1, and an inclined plate 13 is installed at the bottom of the support platform 12.

A protective glass cover 16 is installed on the outer wall of the support platform 12, and the illuminating lamp 15 is located inside the protective glass cover 16. The existing moving route of the guide wire body 2 is viewed by an infrared device outside, and when the existing catheter body 1 moves to the place where treatment is required, the blood vessel wound is observed. The light inside the tube is dim, and the medical staff cannot see the treatment site more clearly. Therefore, it is necessary to illuminate the treatment site after the catheter body 1 is moved to the treatment position, so that the medical staff can observe the situation at any time. When the catheter body 1 is moved to the site that needs treatment, the battery box 14 is powered on according to the needs of the medical staff, and then the lighting lamp 15 illuminates the treatment site, which is convenient for the staff to check on the infrared equipment. The protective glass cover 16 is used to protect the lighting lamp 15, and the inclined plate 13 prevents the drug from remaining on the support platform 12, so that the catheter body 1 has lighting, which is convenient for the medical staff to view the treatment site.

[0030] Working principle: the guidewire body 2 passes through the inside of the blood vessel, and the medical staff moves the guidewire body 2. The developing mark 3 can help the medical staff understand the exact position of the guidewire body 2, and then push the catheter body 1 along the extension direction of the guidewire body 2 to the position of the blood vessel that needs to be treated, so that it is convenient for the medical staff to apply medicine to the part that needs to be treated. The existing catheter body 1 and guidewire body 2 do not quickly stop bleeding at the bleeding part in the blood vessel, which reduces the application scope of the surgical guidewire. Therefore, it is necessary to improve this so that the surgical guidewire has a hemostatic function, which can quickly stop bleeding at the bleeding part inside the blood vessel and enhance its application scope. When bleeding occurs in the blood vessel, after the catheter body 1 moves to the position that needs to be treated, the inflation tube 8 is inflated through the external inflation end, and then the inflated hemostatic balloon 7 is inflated to drive the hemostatic block 9 to move, and the hemostatic block 9 is used to press the bleeding part in the blood vessel to stop bleeding, and the blood stains are adsorbed by the hemostatic layer 10, and the smooth layer 1 1 enables the catheter body 1 to be smoothly moved to the treatment position, so that the catheter body 1 has a hemostatic function, avoiding the situation that hemostasis cannot be performed immediately due to intravascular bleeding. The existing moving route of the guide wire body 2 is viewed by an external infrared device. When the existing catheter body 1 moves to the place where treatment is required, the light in the blood vessel is dim, which causes the medical staff to be unable to see the situation of the treatment place more clearly. Therefore, it is necessary to illuminate the treatment place after the catheter body 1 moves to the treatment position, so that the medical staff can observe the situation at any time. When the catheter body 1 moves to the place where treatment is required, according to the needs of the medical staff, the battery box 14 is powered on, and then the lighting lamp 15 illuminates the treatment place, which is convenient for the staff to view on the infrared device. The protective glass cover 16 is used to protect the lighting lamp 15, and the inclined plate 13 prevents the drug from being retained on the supporting platform 12, so that the catheter body 1 has lighting work, which is convenient for the medical staff to view the treatment place.
