Description

Technical Field

[0001] The utility model relates to the technical field of laser ablation, in particular to a laser ablation and injection, flushing, puncture guidance and auxiliary treatment handle. Background Art

[0002] The Guidelines for the Diagnosis and Treatment of Hemangiomas and Vascular Malformations (2019 Edition) point out that the current mainstream international method for vascular malformations is endovascular sclerotherapy. However, extensive and diffuse lesions require multiple treatments, and the effect is relatively poor. Studies have shown that based on in vivo and in vitro vascular tissue tests, 1470nm semiconductor laser treatment at a power of 6W can achieve the purpose of occluding blood vessels and treatment. This characteristic of 1470nm laser can effectively occlude the blood supply vessels and diseased blood vessels of vascular malformations. Real-time ultrasound-guided puncture can improve surgical safety, accurately determine the scope of the lesion, blood supply vessels, and the characteristics of the surrounding normal nerves and blood vessels, select the optimal puncture point, and guide the puncture process in real time. Ultrasound-guided laser ablation combined with lauromacrogol foam sclerotherapy for the treatment of vascular malformations has better results, fewer treatments, and higher safety. It will replace single endovascular sclerotherapy as a treatment method and is likely to become the industry's treatment standard.

[0003] Laser ablation is a new ablation technology currently used in the treatment of hemangiomas, vascular malformations, and lipolysis. The existing method involves using a long needle or a single catheter to guide the laser fiber into the area to be ablated under ultrasound guidance. However, due to needle length limitations, deep lesions cannot sometimes be ablated. Furthermore, removing the needle or catheter after ablation and reinserting it for injection embolization may result in inconsistent locations, preventing the precise embolization effect achieved after laser ablation.

[0004] In order to solve the above problems, the present application proposes a laser ablation and injection flushing puncture guidance auxiliary treatment handle. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the prior art and provides a laser ablation and injection flushing puncture guidance auxiliary treatment handle.

[0006] The utility model solves the above technical problems with the following technical solutions: a laser ablation and injection flushing puncture guidance auxiliary treatment handle, comprising a guide needle body, the guide needle body comprising an optical fiber front catheter and an injection front catheter, the outer sides of the optical fiber front catheter and the injection front catheter being connected;

[0007] The outer clamping sleeve of the optical fiber front conduit is provided with an optical fiber conduit, and the optical fiber conduit is coaxial with the optical fiber front conduit;

[0008] The outer clamping sleeve of the pre-injection catheter is provided with an injection tube, and the injection tube is not coaxial with the optical fiber pre-injection catheter;

[0009] A handle is installed on the guide needle body.

[0010] The interiors of the optical fiber front conduit and the optical fiber conduit are both adapted to the laser optical fiber. The optical fiber front conduit and the optical fiber conduit are provided to ensure that one end of the laser optical fiber smoothly extends into the lesion.

[0011] A threaded inlet is provided at one end of the injection tube that is not connected to the pre-injection catheter, and the threaded inlet is provided for connection with the syringe.

[0012] A fixing part is installed on the handle, and a through-hole is provided on the fixing part. A mounting groove is provided on the fixing part. A passage connected to the through-hole is provided on the fixing part through the mounting groove. A grip block is movably inserted into the fixing part through the mounting groove. An extrusion plate is installed on one side of the grip block, and the extrusion plate is movably inserted into the fixing part through the passage. The through-hole, mounting groove, passage, grip block and extrusion plate are provided to fix the laser optical fiber.

[0013] The fixing member is installed with a spring through the installation groove, and one side of the gripping block located in the installation groove is connected to one end of the spring. The spring is provided to support and reset the gripping block.

[0014] An anti-slip sheet is installed on the side of the extrusion plate away from the grip block. The anti-slip sheet is provided to increase the friction between the extrusion plate and the laser optical fiber.

[0015] The beneficial effects of the utility model are:

[0016] The puncture point is determined by ultrasound exploration of the lesion size. Under ultrasound guidance, one end of the guide needle body is inserted into the lesion vessel lumen. The laser fiber is then passed through the fiber optic catheter and the fiber optic front catheter in sequence, and one end of the laser fiber is moved into the lesion vessel lumen for ablation. The blood in the lesion is then aspirated with a needle. The lauromacrogol foam is then prepared and injected into the injection tube from the threaded inlet using a syringe. The lauromacrogol foam is then injected into the lesion through the injection tube for sclerosis and injection embolization, achieving the best treatment effect and reducing the number of treatments.

[0017] When one end of the laser fiber is in the lesion blood vessel cavity, press the grip block with your hand, so that the grip block drives the squeezing plate to move and squeeze the outside of the laser fiber to fix the laser fiber. Try to move the laser fiber away from the lesion after the position is determined. BRIEF DESCRIPTION OF THE DRAWINGS
