Abstract
Description
Technical Field
[0001] This utility model belongs to the field of interventional therapy guidance technology, specifically relating to a guidewire guiding device for interventional therapy. Background Technology
[0002] Interventional therapy is an emerging treatment method that falls between surgical and medical treatments. It includes endovascular and non-vascular interventional therapies. Interventional therapy is a minimally invasive treatment method that involves creating tiny channels, a few millimeters in diameter, in blood vessels or skin, or through existing channels in the body, without exposing the lesion. Under the guidance of imaging equipment (angiography machine, fluoroscopy machine, CT, MRI, ultrasound), the lesion is treated locally. In interventional therapy, a guide wire device is usually used to guide the wire to the lesion to facilitate drug injection.
[0003] However, existing guidewires cannot be fixed after insertion and when medication is injected, and the rotation of the guidewire can easily cause discomfort to the patient. Moreover, during guidance, doctors usually rotate the guidewire directly, which makes it difficult to control the angle of rotation and accurately rotate the guidewire into the blood vessel that needs to be entered. Utility Model Content
[0004] The purpose of this invention is to provide a guidewire guiding device for interventional therapy to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a guidewire guiding device for interventional treatment, comprising a guidewire body and an auxiliary guiding device for guiding the guidewire body, wherein the guidewire body is provided with a limiting structure and an auxiliary rotation structure, the limiting structure includes a detachable clamping ring, the clamping ring is provided with a first locking block, and the auxiliary rotation structure includes a fixing ring sleeved on the guidewire body and a handle, wherein a connecting rod is provided between the handle and the fixing ring.
[0006] Preferably, the auxiliary guiding device includes a catheter and a puncture needle that are sleeved and connected together, the top of the catheter is provided with a communicating sleeve, and one side of the sleeve is provided with a communicating branch tube.
[0007] Preferably, the top of the branch pipe is provided with a first locking hole that cooperates with the first locking block, and the clamping ring is fixedly connected to the branch pipe through the first locking block and the first locking hole.
[0008] Preferably, the clamping ring consists of two semi-rings, one side of which is provided with an adjustment part and the other side is open.
[0009] Preferably, one of the semi-rings is provided with a second locking block, and the other semi-ring is provided with a second locking hole that cooperates with the second locking block, and the two semi-rings are engaged and connected through the second locking hole and the second locking block.
[0010] Preferably, the guidewire body has a bendable guidewire head at its entry end for easy guidance.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] (1) This utility model sets up a clamping ring, which consists of two half rings. The guide wire body is clamped between the two half rings, and the second locking hole and the second locking block engage to make the two half rings tightly fixed. The clamping ring is fixed on the branch tube by the cooperation of the first locking hole and the first locking block, ensuring that the guide wire will not rotate randomly during injection, which can reduce the patient's discomfort.
[0013] (2) By setting a fixing ring, the present invention has a handle on the fixing ring. When in use, the fixing ring can be put on the end of the guide wire body. The fixing ring and the guide wire body can be rotated by the handle, which makes it easier to control the rotation angle of the guide wire body and guide it to the lesion.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 As shown, the present invention provides the following technical solution: a guidewire guiding device for interventional treatment, including a guidewire body 5 and an auxiliary guiding device for guiding the guidewire body 5. The guidewire body 5 is provided with a limiting structure and an auxiliary rotation structure. The limiting structure includes a detachable clamping ring 11, and a first locking block 12 is provided on the clamping ring 11. The auxiliary rotation structure includes a fixing ring 8 sleeved on the guidewire body 5 and a handle 7. A connecting rod is provided between the handle 7 and the fixing ring 8.
[0022] The auxiliary guiding device includes a catheter 3 and a puncture needle 4 connected together. The top of the catheter 3 is provided with a communicating sleeve 2, and a communicating branch tube 1 is provided on one side of the sleeve 2.
[0023] The top of the branch pipe 1 is provided with a first locking hole 10 that cooperates with the first locking block 12, and the clamping ring 11 is fixedly connected to the branch pipe 1 through the first locking block 12 and the first locking hole 10.
[0024] In response to the above, when using the guidewire guiding device for interventional treatment, the puncture needle 4 is first inserted into the patient's blood vessel, and then the catheter 3 is placed on the end of the puncture needle 4. The cannula 2 is in a sealed state. At this time, the guidewire body 5 is introduced into the blood vessel from the branch tube 1, and the guidewire body 5 is guided to the lesion with the help of imaging equipment.
[0025] During the guidance process, if it is necessary to adjust the direction of the guide wire body 5, the fixing ring 8 is fitted on the guide wire body 5. By rotating the fixing ring 8 and the guide wire body 5 through the handle 7, the direction of the guide wire body 5 can be adjusted.
[0026] When the guidewire body 5 reaches the lesion, the clamping ring 11 can be clamped in a fixed position, and the first locking block 12 on the clamping ring 11 can be inserted into the first locking hole 10 on the branch tube 1 to limit and fix the guidewire body 5, so as to ensure that the guidewire body 5 will not rotate randomly when injecting drugs, thereby reducing the patient's discomfort.
[0027] Preferred, such as Figure 1 , Figure 3 and Figure 4As shown, in this utility model, the clamping ring 11 is composed of two half-rings. One side of the two half-rings is provided with an adjustment part 9. From the adjustment part 9, the two half-rings can be opened or closed together to facilitate fixing them to the guide wire body 5. The other side is set in an open shape to facilitate the installation and disassembly of the clamping ring 11.
[0028] Specifically, such as Figure 4 As shown, in this utility model, one half-ring is provided with a second locking block 112, and the other half-ring is provided with a second locking hole 111 that cooperates with the second locking block 112. The second locking hole 111 and the second locking block 112 are provided on the side of the opening of the two half-rings. The second locking block 112 is inserted into the second locking hole 111 so that the two half-rings are combined into a circle, so as to be fixed on the guide wire body 5. The two half-rings are connected by the second locking hole 111 and the second locking block 112.
[0029] Specifically, such as Figure 1 As shown, in this utility model, the guidewire body 5 is provided with a bendable guidewire head 6 at its entry end for easy guidance. The bend of the bendable guidewire head 6 is arc-shaped, which makes it easier to enter blood vessels in different locations.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
