Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a guide wire fixing device used for vascular interventional treatment. Background Art
[0002] Vascular interventional therapy is a minimally invasive treatment method that makes a tiny channel with a diameter of several millimeters in the blood vessel without exposing the lesion through surgery, and treats the lesion locally under the guidance of imaging equipment. During vascular interventional therapy, especially when more than two blood vessels need to be treated at the same time, interventional therapy is usually performed from the same puncture hole. In the existing interventional therapy of multiple blood vessels, there is no special device for guidewire fixation, and the following problems usually exist: First, after two or more guidewires enter the blood vessel with bifurcated lesions, the entanglement of the external parts causes the guidewires at the bifurcation of the blood vessel to become entangled, hindering the delivery of devices such as stents and balloons to the target lesion, thereby increasing the difficulty of the operation and the occurrence of complications, threatening the patient's life safety; second, the tip of the guidewire is hard and as thin as a needle tip, and it is easy to penetrate the sterile surgical tablecloth and be contaminated during the operation, resulting in guidewire contamination, which is not easy to detect, and ultimately increases the risk of nosocomial infection caused by the operation. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of the design of the utility model is to provide a guidewire fixing device for vascular interventional treatment, which is specifically achieved through the following technical solutions:
[0004] A guidewire fixing device for vascular interventional treatment includes a guidewire fixing seat, the guidewire fixing seat includes a base and a pressing rod, the base is provided with a groove along its length direction, one end of the pressing rod is hingedly arranged in the groove, and the pressing rod is integrally provided with an arc-shaped hole opening downward, the arc-shaped hole is used for the guidewire to pass through, and a protective cover is also provided at the end of the guidewire.
[0005] Furthermore, two pressing rods are provided, and the two pressing rods are symmetrically arranged in the groove at an interval, and the other end of the pressing rod extends out of the end of the base.
[0006] Furthermore, the width of the groove matches the thickness of the pressing rod.
[0007] Furthermore, the protective cover comprises a shell for inserting the end of the guide wire and a cap body used in conjunction with the shell, and the cap body is plugged and arranged on the shell.
[0008] Furthermore, the shell is a columnar body with one end closed and the other end open, a plug-in column extending from the middle of the cap body protrudes from the edge of the cap body, the outer diameter of the plug-in column matches the inner diameter of the shell, and the inner diameter of the cap body matches the outer diameter of the shell.
[0009] The utility model has the advantages of simple structure, reasonable design and easy implementation. The different guide wires can be completely separated in the extracorporeal parts by means of the arranged base and the pressure rod, so that the position of the guide wire in the extracorporeal part is relatively fixed, which can effectively prevent the entanglement of the guide wire during the surgical operation without affecting the flexibility when operating the guide wire. The arrangement of the protective cover at the end of the guide wire can effectively prevent the end of the guide wire from penetrating the table cloth, thereby avoiding contamination of the operating table when the guide wire moves back and forth.

[0014] The present invention is further described below in conjunction with the accompanying drawings in order to better understand the present technical solution.
[0015] like Figure 1-2 As shown, the utility model is a guidewire fixing device for vascular interventional treatment, which includes a guidewire fixing seat 1, which includes a base 2 with a wooden structure, and two pressing rods 3 with a wooden structure installed on the base 2. In order to facilitate the pressing action of the pressing rod 3, a groove 4 is opened on the base 2 along its length direction, one end of the pressing rod 3 is hingedly set in the groove 4, the width of the groove 4 is consistent with the thickness of the pressing rod 3, two pressing rods 3 are provided, and the two pressing rods 3 are symmetrically arranged in the groove 4 at intervals, and the other end of the pressing rod 3 extends out of the end of the base 2, so as to facilitate the operation of the pressing rod 3.
[0016] Continue reading Figure 1-2 In order to facilitate the relative fixation of the position of the guide wire 6, an arc-shaped hole 5 with an opening downward is integrally provided on the pressing rod 3, and the arc-shaped hole 5 is used for the guide wire 6 to pass through. In order to prevent the end of the guide wire 6 from penetrating the surgical sterile tablecloth, a protective cover 7 is also provided at the end of the guide wire 6. The protective cover 7 includes a shell 8 for inserting the end of the guide wire 6 and a cap body 9 used in conjunction with the shell 8. The cap body 9 is plugged into the shell 8. Specifically, the shell 8 is a columnar body with one end closed and the other end open. A plug-in column protruding from the edge of the cap body extends from the middle of the cap body 9. The outer diameter of the plug-in column coincides with the inner diameter of the shell 8, and the inner diameter of the cap body 9 coincides with the outer diameter of the shell 8.
