Description

一种用于下肢静脉曲张的腔内激光治疗系统 One kind of varicose veins for endovenous laser treatment system

技术领域 FIELD

[0001] 本发明涉及一种用于下肢静脉曲张的腔内激光治疗系统,属于医疗器械技术领域。 [0001] The present invention relates to a system for laser treat varicose veins, belonging to the technical field of medical instruments.

背景技术 Background technique

[0002] 目前下肢静脉曲张的治疗方法有多种,包括大隐静脉高位结扎加点式剥脱术、硬化剂注射加压迫治疗、血管内射频消融、内镜下的穿通静脉切除术、激光静脉闭合手术等。 [0002] There are many, including saphenous vein high point decortication ligation, sclerotherapy plus compression therapy, radiofrequency ablation of the blood vessel through the endoscopic phlebectomy, vein closure laser surgical treatment of varicose veins Wait. 而激光静脉闭合手术是1997年首次应用于临床,治疗下肢静脉曲张。 The laser vein surgery was closed in 1997 for the first time used in clinical treatment of varicose veins. 我国自2003年以来, 已有二百多家医院先后开展了这项新技术。 China since 2003, more than two hundred hospitals have carried out this new technology. 与传统高位结扎加点式剥脱手术相比,因为无需剥脱大隐静脉主干,也无需做小切口剥脱小腿处曲张的静脉及交通静脉,真正具有创伤小,小腿无切口的优点。 Compared with the traditional high ligation point ablative surgery, since no great saphenous vein stripping, it requires very small incision in the leg varicose vein and communicating veins stripping, truly trauma, leg unnotched advantages. 激光静脉闭合术与硬化剂注射和压迫治疗相比,后者硬化剂有直接注入深静脉引起肺栓塞的可能性,造成致命性的后果,硬化剂更容易形成组织坏死、溃疡等并发症。 Laser surgery is closed compared to intravenous injection and compression therapy hardeners, hardeners which are directly implanted deep vein potential to cause pulmonary embolism, resulting in fatal consequences hardener easier to form a tissue necrosis, ulcers and other complications. 硬化剂治疗具有更大的手术风险。 Sclerotherapy have a greater risk of surgery. 内镜下的穿通静脉切除手术与激光静脉闭合手术相比,内镜需要潜行分离皮肤、形成腔镜通道,表面具有微创的特点,实际上具有一定的组织分离、损伤程度,更需要成套的内镜系统和术中离断血管的超声刀,这些设备不仅需要医生具备内镜下的操作基本功,而且极大的提高了手术费用,不利在广大基层医院的全面推广。 Compared veins through intravenous closed surgery laser endoscopic surgery, endoscopic required separation sneak skin, endoscopic channel is formed, the surface characteristics of minimally invasive, in fact has a certain tissue separation, the degree of damage, set of need endoscopic system and intraoperative ultrasound vascular amputation knife, these devices not only require doctors to operate with endoscopic basic skills, but also greatly improves the operation costs, unfavorable comprehensive promotion of grassroots hospitals. 与激光静脉闭合手术相比,血管内射频消融手术需要专门的消融导管,导管接通后产生热量,但因血管内高温破坏血管内膜,较激光静脉闭合手术更大地增加了下肢皮肤烫伤的风险,且血红蛋白对射频能量的吸收不具有特异性,降低了射频能量的利用效率。 Compared with the risk of venous closure laser surgery, endovascular surgery requires special radiofrequency ablation catheter ablation, the catheter is turned on to generate heat, but heat damage intima intravascular, intravenous closed surgery greater than the laser increases the lower limb skin burns and RF energy is absorbed by hemoglobin is not specific for, reducing the utilization efficiency of radio frequency energy. 另外因消融导管有进入深静脉的危险,术中同样需要B超监测。 Further, because of the risk of ablation catheter into deep veins, surgery also need B-monitoring. 这也增加了手术的复杂性。 This also increases the complexity of the surgery.

[0003] 腔内激光治疗静脉曲张的原理是激光发出能量,被血红蛋白和周围组织吸收,组织在高温下汽化,使内皮细胞和内膜广泛受热损伤,诱导静脉全程血栓形成,静脉血栓机化、纤维化,静脉壁永久闭塞。 [0003] The laser treat varicose veins principle of laser light energy is absorbed by hemoglobin and the surrounding tissue, tissue vaporization at high temperatures, so that extensive heat endothelial cells and intimal damage, inducing full venous thrombosis, venous thrombosis machine, fibrosis, permanent occlusion of the vein wall. 该手术较其它手术有许多优点,只需局部穿刺,创伤小,出血少,术后基本无疤痕,手术容易操作,现在越来越受到广大患者及医生的欢迎。 The surgery has many advantages compared to other procedures, only local puncture, less trauma, less bleeding and almost no scars, surgery is easy to operate, and now more and more by the majority of patients and doctors welcome. 但该项技术目前没有专门的手术器械,在手术中不能观察导管和导丝头端在静脉中的位置,存在将导管和光纤误导入下肢深静脉系统的危险。 However, this technology is currently no specific surgical instruments, catheters and guidewires can not be observed in the tip of vein location, the presence of the catheter and the risk of misleading fiber deep venous system during surgery. 误入深静脉系统的光纤即使不发射激光能量,也可以损伤深静脉内膜,形成深静脉血栓,威胁患者生命。 Strayed deep venous system without the optical fiber emitting the laser energy, it can be deep intimal injury, deep vein thrombosis, threaten the lives of patients.
