Description

Technical Field

[0001] The utility model relates to the technical field of surgical medical instrument parts, and more particularly to a guiding structure of a vein stripping device. Background Art

[0002] Varicose veins of the lower extremities are a common and frequently occurring surgical condition, with an overall incidence of approximately 10% and ranking first among vascular surgery morbidity rates. Mild cases may present with minor superficial vein dilation or varicose veins, while severe cases may cause swelling, heaviness, soreness, itching, hyperpigmentation, and ulcers in the affected limbs, leading to decreased or even loss of productivity and severely impacting the patient's quality of life.

[0003] Common treatments include laser therapy, electrocoagulation, sclerotherapy, medication, and surgery. Surgery is currently the most effective and recognized treatment for this condition. Surgical stripping of the great saphenous vein requires a vein stripper. Traditional strippers typically consist of two conical metal heads and a multi-strand metal wire rope with a polymer tube in the middle.

[0004] Because the metal heads at both ends of traditional strippers are relatively thick, generally with an outer diameter of 2.8~3.5mm, and the veins become spider-web-like, earthworm-like, or hard nodules like tree tumors after bending, the thicker heads of the strippers cannot pass through the blood vessels smoothly and need to be continuously segmented incisions. This can easily lead to problems such as thrombophlebitis, obvious pain in the affected area, and hematoma after the operation, and it takes a long time to relieve. Utility Model Content

[0008] The guide wire includes a rear end nickel-titanium alloy wire and a front end spring coil, the rear end nickel-titanium alloy wire is fixedly connected to one end of the guide end, the front end spring coil is fixedly connected to the end of the rear end nickel-titanium alloy wire away from the guide end, the outer side of the rear end nickel-titanium alloy wire is fixedly connected to the zebra cortex, and the zebra cortex covers the rear end nickel-titanium alloy wire on its inner side, the outer side of the front end spring coil is fixedly connected to the TPU layer, and the outer side of the TPU layer is coated with a hydrophilic coating.

[0009] As a further description of the above technical solution: a threaded hole is provided at one end of the guide end away from the rear end nickel-titanium alloy wire, and the guide end is threadedly connected to the front end screw of the stripper through the threaded hole.

[0010] As a further description of the above technical solution: the length of the guide wire is 10cm-250cm, the overall outer diameter of the guide wire is a variable diameter structure, and the range of the outer diameter of the guide wire is 0.5mm-1.5mm.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] This solution has a simple structure, is easy to operate, and is simple to install and replace. The guide end and the front end screw of the stripper are combined into a new structure of the vein stripper before entering the blood vessel. The hydrophilic coating allows the front end spring coil to flexibly pass through the blood vessel, allowing the guide stripper to smoothly pass through the vein, reducing damage to the blood vessel wall. At the same time, it can also reduce the number of incisions and there is no need to perform segmented incisions continuously.
