Description

Technical Field

[0001] This utility model relates to the field of varicose vein tools, specifically to a minimally invasive varicose vein picking, peeling, and ligation tool. Background Technology

[0002] Varicose veins are a common vascular disease, and traditional treatments often have some shortcomings. In the past, surgical methods for treating varicose veins may have been quite invasive, causing significant trauma to the patient's body, resulting in higher surgical risks and a relatively high incidence of postoperative complications. This brought considerable pain and recovery time to patients.

[0003] Traditional surgical tools may have limitations in terms of operational precision, making it difficult to accurately locate and treat varicose veins, thus affecting surgical outcomes. Furthermore, previous surgical tools were relatively single-function, often requiring the use of multiple tools in combination, which not only increased the complexity of the surgery but also reduced its efficiency.

[0004] When dealing with arteriovenous sheaths, conventional tools may not be able to reduce damage to surrounding tissues as effectively as the blunt dissector head of this invention, thus increasing surgical risks.

[0005] Moreover, traditional surgical tools may not be flexible enough in terms of adjustability, making it difficult to make convenient adjustments according to the actual needs of the surgery, which brings inconvenience to the surgical operation.

[0006] During vein ligation, traditional tools may not provide suitable suture holes and convenient operation methods like the lateral bending needle in this invention, thus failing to ensure effective ligation and potentially affecting the final surgical outcome.

[0007] In summary, existing techniques and tools for treating varicose veins have many problems, necessitating a more advanced and effective solution to improve treatment outcomes, reduce patient suffering, and enhance surgical safety and efficiency. This novel minimally invasive hook-based stripping and ligation tool for varicose veins is designed to address these issues. Therefore, we have made improvements and proposed a minimally invasive hook-based stripping and ligation tool for varicose veins. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0034] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1: Please refer to Figures 1-5 A minimally invasive varicose vein removal and ligation tool includes a lateral curved needle handle 1, a lateral curved needle 4 at the end of the lateral curved needle handle 1, a lateral curved needle thread hole 41 on the lateral curved needle 4, a double-headed handle placement cavity 5 in the hollow interior of the lateral curved needle handle 1, a double-headed handle 6 inserted into the double-headed handle placement cavity 5, a peeler 9 at one end of the double-headed handle 6, a peeler thread hole 91 on the peeler 9, and a hook 11 at the other end of the double-headed handle 6.

[0036] The end of the side-bending needle handle 1 is provided with a tapered head 2, and the end of the tapered head 2 has a side-bending needle insertion hole 3. A side-bending needle 4 is inserted into the side-bending needle insertion hole 3, and the side-bending radius R of the side-bending needle 4 is in the range of 2mm to 4mm.

[0037] The double-ended grip 6 has a threaded cap 7 at one end, and a peeler insertion hole 8 at the end of the threaded cap 7, into which a peeler 9 is inserted. The other end of the double-ended grip 6 has a hook fixing plug 10, into which a hook 11 is inserted. The side-bending needle hole 41 is elliptical, with a width of 0.2mm to 0.9mm. The peeler hole 91 is elliptical, with a width of 0.1mm to 1mm. The end of the double-ended grip that rests in the inner cavity 5 has an internal thread 51, which mates with the threaded cap 7. The peeler 9 is a blunt peeling head.

[0038] The working principle of the minimally invasive varicose vein removal and ligation tool is as follows:

[0039] First, a 2mm wide incision is made in the skin using a scalpel to avoid damaging the blood vessels too deeply. Then, a lateral curved needle (4) is inserted from one side of the incision, penetrating deep and bypassing the arteriovenous sheath from the bottom. The needle tip exits from the other side of the incision, lifting the arteriovenous sheath. The sheath is then bluntly dissected using the end of the dissector (6) to expose the vein. The vein is then lifted with a hook needle, avoiding the artery and accompanying nerves. The lateral curved needle (4) is withdrawn, and a suture is placed at the lateral curved needle suture hole (41), passing through the folded gap of the vein lifted by the hook needle. The vein is ligated and then returned to the subcutaneous tissue. The procedure is now complete. The lateral curved needle (4) lifting the arteriovenous sheath provides ample tissue exposure, facilitating pure dissection with the dissector (9). This improves surgical efficiency, reduces tissue damage, and lowers surgical risks throughout the procedure.

[0040] Throughout the procedure, the lateral curved needle 4 lifts the arteriovenous sheath, fully exposing the tissue and facilitating pure dissection by the dissector 9. This design improves surgical efficiency, reduces tissue damage, and lowers surgical risks. Furthermore, the oval-shaped suture holes of the lateral curved needle and dissector facilitate suture threading. The engagement of the double-ended gripper with the threaded cap secures the gripper within the cavity, ensuring operational stability.

[0041] Example 2: A minimally invasive varicose vein removal and ligation tool, comprising a lateral curved needle handle 1, with a conical head 2 at one end and a lateral curved needle insertion hole 3 at the end of the conical head 2. A lateral curved needle 4 is inserted into the lateral curved needle insertion hole 3, and a lateral curved needle thread hole 41 is provided on the lateral curved needle 4. The interior of the lateral curved needle handle 1 is hollow and has a double-ended handle placement cavity 5. A double-ended handle 6 is inserted into the double-ended handle placement cavity 5. A threaded cap 7 is provided at one end of the double-ended handle 6, and a peeler insertion hole 8 is provided at one end of the threaded cap 7. A peeler 9 is inserted into the peeler insertion hole 8, and a peeler thread hole 91 is provided on the peeler 9. A hook fixing plug 10 is provided at the other end of the double-ended handle 6, and a hook 11 is inserted into the hook fixing plug 10.

[0042] The side-bending needle hole 41 is elliptical, with a width of 0.2mm to 0.9mm. The peeling thread hole 91 is elliptical, with a width of 0.1mm to 1mm. The end of the double-ended grip rod placement cavity 5 is provided with an internal thread 51, which mates with a threaded cap 7. By tightening the threaded cap 7 onto the internal thread 51 at the end of the double-ended grip rod placement cavity 5, the double-ended grip rod 6 is fixed within the double-ended grip rod placement cavity 5. The peeling head 9 is a blunt peeling head.

[0043] The procedure for using a minimally invasive varicose vein removal and ligation tool:

[0044] 1. Surgical preparation: Make a 2 mm wide incision in the skin with a scalpel to avoid damaging blood vessels by making it too deep.

[0045] 2. Needle Insertion and Sheath Removal: Insert the lateral curved needle 4 from one side of the incision, guiding it smoothly into the surgical site using the conical head 2. After the lateral curved needle 4 has penetrated deeply, it passes around the arteriovenous sheath from the bottom and then exits from the other side of the incision. At this point, the arteriovenous sheath can be lifted to provide a clear view for subsequent procedures.

[0046] 3. Dissection and exposure: Using the blunt dissection head of the dissector 6, gently dissect the arteriovenous sheath to expose the vein.

[0047] 4. Lifting and Ligating: Use hook 11 to lift the exposed vein, taking care to avoid arteries and accompanying nerves. Then, withdraw the lateral bend needle 4, thread the needle through the lateral bend needle thread hole 41 of the lateral bend needle 4, and pass the thread through the folded gap of the vein lifted by the hook needle to ligate the vein.

[0048] 5. Reduction and completion of the procedure: After ligation, the treated vein is returned to the subcutaneous tissue, and the procedure is completed.

[0049] Throughout the procedure, the lateral curved needle 4 lifts the arteriovenous sheath, fully exposing the tissue and facilitating pure dissection by the dissector 9. This design improves surgical efficiency, reduces tissue damage, and lowers surgical risks. Furthermore, the oval-shaped suture holes of the lateral curved needle and dissector facilitate suture threading. The engagement of the double-ended gripper with the threaded cap secures the gripper within the cavity, ensuring operational stability.

[0050] Example 3: Procedure of a minimally invasive varicose vein dissection and ligation tool: First, a 2 mm wide incision is made in the skin using a scalpel to avoid excessively deep damage to the blood vessel. Then, a lateral curved needle 4 is inserted from one side of the incision, penetrating deep and bypassing the arteriovenous sheath from the bottom. The needle tip exits from the other side of the incision, lifting the arteriovenous sheath. The sheath is bluntly dissected using the end of the dissector 6 to expose the vein. The vein is then lifted with a hook, avoiding the artery and accompanying nerves. The lateral curved needle 4 is withdrawn, and a suture is placed at the lateral curved needle suture hole 41, passing through the folded gap of the vein lifted by the hook. The vein is ligated and then returned to the subcutaneous tissue. The procedure is complete. The lateral curved needle 4 lifts the arteriovenous sheath, fully exposing the tissue and facilitating pure dissection by the dissector 9. Throughout the procedure, this improves surgical efficiency, reduces tissue damage, and lowers surgical risks.
