静脉曲张的结扎器械Ligation device for varicose veins

技术领域technical field

本发明涉及医疗器械领域，具体而言，涉及一种静脉曲张的结扎器械。The invention relates to the field of medical devices, in particular to a ligation device for varicose veins.

背景技术Background technique

静脉曲张是指由于血液淤滞、静脉管壁薄弱等因素，导致的静脉迂曲、扩张。身体多个部位的静脉均可发生曲张，比如痔疮其实就是一种静脉曲张，临床可见的还有食管胃底静脉曲张、精索静脉曲张及腹壁静脉曲张等等。静脉曲张最常发生的部位在下肢。值得强调的是，静脉曲张是其他病变的继发表现。Varicose veins refer to the tortuous and dilated veins caused by factors such as blood stasis and weak vein walls. Varicose veins can occur in many parts of the body. For example, hemorrhoids are actually a type of varicose veins. Clinically, there are esophagus and gastric varices, varicoceles, and abdominal wall varicosities. The most common site of varicose veins is the lower extremities. It is worth emphasizing that varicose veins are secondary manifestations of other lesions.

下肢静脉曲张有穿弹力袜、注射硬化剂、手术剥除等治疗方法，深静脉瓣膜功能不全，可作瓣膜修复手术和腔镜下交通支结扎术等。下肢静脉曲张也可能提示其他疾病存在，需积极治疗原发病。Varicose veins of the lower extremities can be treated by wearing elastic stockings, injecting sclerosant, and surgical stripping. Deep vein valve insufficiency can be used for valve repair surgery and endoscopic communicating branch ligation. Varicose veins of the lower extremities may also indicate the existence of other diseases, and the primary disease needs to be actively treated.

对于大隐静脉曲张或者小隐静脉曲张而言，大隐静脉起于足背静脉弓内侧端，经内踝前方，沿小腿内侧缘伴隐神经上行，经股骨内侧髁后方约2cm处，进入大腿内侧部，与股内侧皮神经伴行，逐渐向前上，在耻骨结节外下方穿隐静脉裂孔，汇入股静脉，其汇入点称为隐股点。小隐静脉系小腿的主要浅静脉之一。小隐静脉在足外侧，起自足背静脉弓，经外踝后方，沿小腿后面上行，过腓肠肌内、外两头间到腘窝，穿筋膜注入腘静脉。此静脉在行程中有许多小支与大隐静脉的属支相吻合。由于动力的关系，小隐静脉回流易受阻，多易发生曲张，有的可形成血栓和发生血栓性脉管炎；曲张的静脉破溃后形成小腿溃疡、长期不愈。For varices of the great saphenous or small saphenous veins, the great saphenous vein originates from the medial end of the dorsal venous arch of the foot, passes in front of the medial malleolus, runs along the medial border of the calf with the saphenous nerve ascending, passes about 2cm posterior to the medial femoral condyle, and enters the inner thigh It goes along with the medial femoral cutaneous nerve, and gradually moves forward and upward, passes through the hiatus of the saphenous vein below the pubic tubercle, and joins the femoral vein. The small saphenous vein is one of the main superficial veins of the lower leg. The small saphenous vein is on the lateral side of the foot, originating from the dorsal venous arch of the foot, passing behind the lateral malleolus, ascending along the back of the calf, passing between the medial and lateral ends of the gastrocnemius muscle to the popliteal fossa, passing through the fascia and injecting into the popliteal vein. This vein has many small branches that coincide with the subordinate branches of the great saphenous vein during its course. Due to the dynamic relationship, the return of the small saphenous vein is easily blocked, and varicose veins are prone to occur, and some can form thrombosis and thromboangiitis.

针对大隐静脉曲张或者小隐静脉曲张，目前包括以下三种治疗方式：For large saphenous varicose veins or small saphenous varicose veins, the following three treatments are currently included:

第一种传统剥脱，优点在于直视下解决，效果确切。但需要切开，创面太大、恢复慢、易感染；第二种射频、激光或者微创，虽然微创恢复快，但缺点在于对于直径超过14mm的静脉主干的无法确切闭合，且费用高；第三种为硬化剂或者胶，但是对于静脉主干闭合效果不确切，而且很有可能导致硬化剂或胶经过主干进入肺内。The first type of traditional peeling has the advantage of being solved under direct vision, and the effect is exact. However, incision is required, the wound surface is too large, the recovery is slow, and it is susceptible to infection; the second type of radiofrequency, laser or minimally invasive, although minimally invasive recovery is fast, but the disadvantage is that the main vein with a diameter of more than 14mm cannot be closed accurately, and the cost is high; The third type is sclerosing agent or glue, but the effect on the closure of the main vein is not exact, and it is likely to cause the sclerosing agent or glue to enter the lung through the main trunk.

为了解决上述问题，中国实用新型专利的授权公告号CN211723306U公开了一种静脉曲张的结扎工具，静脉曲张的结扎工具包括导管、导丝组件和鞘管。导管的端部可活动地位于静脉曲张的静脉主干的周边，使静脉主干周边形成操作空间。导丝组件可移除地穿设在导管内，导丝组件包括第一导丝、第二导丝连接第一导丝和第二导丝之间的结扎结构，结扎结构位于操作空间内。鞘管可移除地套设在第二导丝外。在操作空间内，活动导管使导管的端部调节结扎结构结扎于静脉主干上。In order to solve the above problems, the Chinese Utility Model Patent Authorization Announcement No. CN211723306U discloses a ligation tool for varicose veins. The ligation tool for varicose veins includes a catheter, a guide wire assembly and a sheath. The end of the catheter is movably positioned around the venous trunk of the varicose veins, so that an operation space is formed around the venous trunk. The guide wire assembly is removably inserted in the catheter, and the guide wire assembly includes a first guide wire and a second guide wire connecting a ligation structure between the first guide wire and the second guide wire, and the ligation structure is located in the operation space. The sheath tube is removably sheathed over the second guide wire. In the operation space, the movable catheter makes the end adjustment ligation structure of the catheter ligated on the main vein of the vein.

但是，在使用上述的静脉曲张的结扎工具进行结扎的过程中，第一导丝绕过静脉主干后在鞘管内被导管推出，使得操作复杂的问题。However, during the ligation process using the above varicose vein ligation tool, the first guide wire is pushed out of the sheath after bypassing the main vein, which complicates the operation.
