Problems solved by technology

However, different coronary guide wires are often of the same color and similar in length, making it difficult to identify in vitro. In order to avoid mishandling the coronary guide wires, the operator often needs to pull one or more guide wires and simultaneously observe the display screen to guide the wires. The displacement of the tip of the wire to determine the ownership of the guide wire not only increases the operation time, but also increases the dose of X-ray radiation and the amount of contrast agent used by the patient. state, it is easy to entangle with each other, and it is difficult to send balloons and other equipment
[0006] In addition, when the staff in the catheterization room is tense, or when the assistant cannot be in place in time for emergency coronary intervention, the operator alone operates the guide wire without the cooperation of the assistant, and it is difficult to send the balloon or other equipment along the coronary guide wire. , affect the operation process, and may delay the treatment time of emergency surgery to a certain extent

Embodiment 1

[0044] Because in the prior art, when performing interventional surgery, after the tail end of the coronary guide wire is penetrated into the lumen of equipment such as balloon or stent bag or thrombus aspiration catheter, it is necessary to straighten the coronary guide wire by an assistant and manually Fixed on the table, the operator puts the above-mentioned equipment in by hand, and the assistant releases the fixed hand; when the staff in the catheterization room is nervous, or when the assistant cannot be in place in time for emergency coronary intervention, the operator operates the catheter alone. The wire lacks the cooperation of the assistant, and it is difficult to send the balloon or other equipment along the coronary guide wire. In order to solve this problem, this embodiment 1 provides a combined medical guide wire fixing fixture. When performing interventional operations, the guide wire can be directly put into the fixing fixture, and the fixing fixture can be pas...

Embodiment 2

[0057] refer to Figure 7-Figure 8 , this embodiment provides a combined medical guidewire fixing fixture. The difference from the structure of Embodiment 1 is that in this embodiment, the bottom plate 1 is in the shape of a regular hexagonal flat column, and the magnetic connection device is also a magnetic block. 11, respectively embedded in the six sides of the bottom plate 1, and the embedded positions are all at the central position of the sides, and the magnetic poles of the magnetic blocks 11 embedded in the opposite sides are opposite, so as to realize that multiple fixing fixtures can be in a honeycomb shape For quick stitching.

[0058] Further, as Figure 7 , the clamping device is in the same direction as the two diagonals of the bottom surface of the regular hexagon in the length direction, so as to realize the dislocation connection of the guide wires of multiple base plates 1 in the axial direction, so as to avoid the knotting of multiple guide wires, etc. Sit...

Embodiment 3

[0060] In this embodiment, on the basis of the implementation of 1 or 2, two or more parallel clamping devices are provided in the middle of the bottom plate 1 in order to fix more guide wires; furthermore, the magnetic connection on the side of the bottom plate 1 The device is not limited to one form of the magnetic block 11, and may also be in other forms of quick connection, such as plug-in or snap-fit ​​connection structures.

[0061] The present invention has the following advantages:

[0062] (1) During the interventional operation, the guide wire can be directly put into the combined medical guide wire fixing fixture described in this application, which frees hands and saves medical resources.

[0063] (2) When multiple guide wires are required for interventional surgery, multiple fixing fixtures can be combined, and different clamping devices on the fixing fixtures have different distinguishing marks, which can prevent unnecessary errors caused by forgetting the owners...

Abstract

The invention discloses a combined medical guide wire fixing clamp which comprises a bottom plate, the bottom plate is provided with a clamping device, the clamping device comprises two clamping plates arranged side by side, a gap for retaining a guide wire is formed between the two clamping plates, and the bottoms of the two clamping plates are rotatably connected; the button switch is movably connected with the clamping device and used for controlling opening and closing of the clamping device; the magnetic connecting devices are arranged on the side edges of the bottom plates and used for rapidly and magnetically connecting the multiple bottom plates; and the bonding layer is arranged on the bottom surface of the bottom plate in a covering manner and is used for adhering the fixing clamp to a table top or a bed sheet.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a combined medical guide wire fixing fixture. Background technique [0002] Coronary artery disease is the most common cause of sudden death. One of the best treatments is interventional surgery. One of the most commonly used and most critical equipment is the coronary guide wire, which is used to guide the materials that need to be placed in the blood vessel during the intervention. Such as catheters, stents, balloons, etc. [0003] The diameter of the commonly used clinical coronary guide wire is 0.014in (0.356mm). During the operation, the tail end of the coronary guide wire is free on the operating table. balloon or stent balloon or thrombus aspiration catheter and other equipment. [0004] The step of feeding is first to put the tail end of the coronary guide wire into the lumen of the above-mentioned equipment, and then the assistant will straighten the corona...
