A catheter and guide wire fixing and storage device for cerebrovascular interventional surgery

Abstract

The invention discloses a catheter and a guide wire fixing and storing device for cerebrovascular interventional surgery, which includes a fixing component for fixing the joint required in the operation and a storage component for storing the guide wire. The fixing component includes two fixing clips and a guide wire. The connecting rod connecting the two fixing clips, the storage assembly includes a base set at the end of the operating table and a plurality of open storage boxes set on the base, each two storage boxes are connected to each other through a hinge and separated by a One side of the hinge is opened and closed, one side of the storage box is provided with a storage nozzle, and a wetting layer is provided at the storage nozzle, and a guide partition is provided inside the storage box, and the guide partition is connected with the storage nozzle to form a storage cavity. Effectively fix each joint and prevent the tail end of the guide wire from falling off, and reduce the number of medical staff in the operating room to reduce the number of radiation-exposed personnel.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheter and guide wire fixing and storing device for cerebrovascular interventional operations. Background technique [0002] When cerebrovascular patients undergo cerebrovascular interventional surgery, a very long catheter needs to be inserted into the human body. The length of the operating table for placing surgical instruments is 100-150cm, while the length of the guide wire is longer, generally 150-300cm. Because the guide wire is very long, the space for interventional surgery equipment to be placed on the operating table is only the distance from the surgical puncture point to the end of the operating table. The length is limited, and the operating table is narrow with no blocking structures on both sides. Wires and microcatheters, especially the end of the microguide wire, can easily penetrate into the contaminated area outside the operating table from the ope...

Problems solved by technology

[0002] When cerebrovascular patients undergo cerebrovascular interventional surgery, a very long catheter needs to be inserted into the human body. The length of the operating table for placing surgical instruments is 100-150cm, while the length of the guide wire is longer, generally 150-300cm. Because the guide wire is very long, the space for interventional surgery equipment to be placed on the operating table is only the distance from the surgical puncture point to the end of the operating table. The length is limited, and the operating table is narrow with no blocking structures on both sides. Wires and microcatheters, especially the end of the microguide wire, can easily penetrate into the contaminated area outside the operating table from the operating table, and even slip to the ground, which increases the risk of infection, wastes expensive surgical consumables, and increases the financial burden on patients. However, after the application of the micro-guide wire, an assistant is often needed to assist in storage and storage, and to take it out when necessary, which is time-consuming and labor-intensive, and it is still difficult to avoid the phenomenon of contamination and shedding; not only that, but sometimes it is necessary to keep the catheter It is fixed and cannot be dislodged, but due to the outward tension of the catheter and guide wire in the curved blood vessel and the push and pull action on the catheter during the operation, the related catheter and guide wire are easily stuck in the arterial sheath or the medical Y-valve sleeve at the end of the catheter. The outward prolapse and displacement of the entry junction will increase the incidence of surgical complications and failure. It is often necessary for an assistant to firmly pinch the front and rear sections close to a certain junction with two fingers to fix a certain catheter or guide. silk, increase manpower, occupy the operation area, and increase the number of people who are exposed to X-ray radiation

[0003] Although there is a device for fixing the catheter in the prior art, such as the following patent documents: a kind of interventional catheter fixing device for cardiovascular and cerebrovascular treatment with a publication number of CN206792785U and an interventional catheter fixer for cardiovascular and cerebrovascular care with a publication number of CN106730249A , both of these two patent documents provide a catheter fixing device for fixing the catheter, which can avoid the push and pull action on the catheter during the operation, but due to the outward tension of the catheter and the guide wire in the curved blood vessel during the operation , there may still be a small slippage at the junction of the catheter and the arterial sheath, but the existing technology has not done too much research on the junction of the catheter and the end of the catheter
