Description

医用介入导管或导丝固定夹 The medical interventional catheter or guide wire retaining clip

技术领域 FIELD

[0001] 本发明涉及一种介入手术所用导丝及导管的固定装置,特别是涉及一种医用介入导管或导丝固定夹。 [0001] The present invention relates to a device for fixing the guidewire an interventional procedure used catheters and, in particular, relates to a medical guidewire or interventional catheter clip.

背景技术 Background technique

[0002] 目前,介入手术以其微创、有效等优势在心脑血管疾病、肿瘤及非血管疾病等领域得以快速开展。 [0002] Currently, its minimally invasive interventional procedures, effective advantages in mind the field of cerebrovascular disease, cancer and non-vascular diseases, to quickly carry out. 在介入手术中,导丝是手术的最基本器材,介入手术会应用到不同规格的各种导丝,导丝的长度多大于150cm,更长者可达300cm,多数导丝在同台手术中会反复替换应用,而在导丝替换应用时会有部分导丝处于放置备用状态,临床中此时多将备用状态的导丝盘曲后置于盛有肝素盐水的盘中,或以纱布块缠绕后置于器械台上。 In interventional procedures, the guide wire is the most basic surgical equipment, surgical intervention will be applied to all kinds of different specifications of the guide wire, the length of the guidewire how to 150cm, longer by up to 300cm, the majority of the guide wire in the same stage surgery Alternatively repeatedly applied, and in the alternative application will be part of the guide wire is placed guidewire standby state, multiple clinical case coiled guidewire was placed in a standby state after the tray filled with heparinized saline, gauze or wound after the instrument placed on the stage. 但以上处理手段均有弊端,如果导丝过多,均置于同一肝素盐水盘中易造成不同导丝相互缠绕,不易于轻易取出所需导丝,另外长的加强导丝不易于盘曲后置于盘中;如所有导丝均以纱布块缠绕则操作繁琐,影响手术操作过程。 However, the above processing means has drawbacks, too, if the guide wire, all in one easy to cause different heparin saline disc guidewire entangled with each other, is not easily removed easily guidewire desired, additional length of reinforcing wire coiled set easily after intraday; guidewire as all the winding operations are cumbersome gauze, surgical procedure impact. 并且以上操作措施均易于在操作过程中使导丝从无菌手术区失落于有菌区,影响手术操作。 And the above operations are easy to measure during operation manipulation wire from the sterile surgical area lost in the non-sterile area, affects the operation.

[0003] 中国专利文献CN203842150U中公开了一种医用导丝夹持器,其包括上夹体,下夹体和铰接轴,其上夹体和下夹体通过较接轴铰接连接,所述上夹体和下夹体的内侧分别配有弹性材料制成的上啮合齿和下啮合齿;所述上夹体的内侧配有夹持锁定卡,在所述下夹体的对应位置,设有与可调锁定卡配合的固定卡孔。 [0003] Chinese Patent Document CN203842150U discloses a medical guide wire clamp comprising an upper clamp body, a lower clamp body and a hinge shaft on which a clip body and a lower clamp bodies are connected by a hinge joint shaft than the upper the inner body and the lower clamp body respectively interposed with meshing teeth and the meshing teeth on the lower elastic material; the upper inner side of the clip body with a locking clamp, the corresponding position in the lower clamp body, with fixing hole cards and cards with an adjustable locking. 中国专利文献CN100466991C中公开了一种血管介入导丝夹持保护器,其主体是一个由两块能够进行开合动作的硬质构件组成一种可夹持导丝的卡具,在卡具上设有与手术台架相联系的连接机构,其结构复杂,不便于临床应用与维护。 Chinese Patent Document CN100466991C discloses a vascular interventional guidewire protector holder, which is a body capable of opening or closing operation by the two rigid member constituting a guide wire holding fixture may be in the jig connection means associated with the operating table frame, its structure is complex, and not easy to maintain clinical application. 中国专利文献CN201939853U中公开了一种用于医用导管或导丝的夹子,其结构也较为复杂,包括左夹体、右夹体、转轴和扭力弹簧,上述左夹体和右夹体可相互转动地安装在转轴上,左夹体和右夹体处于转轴上方的部分为抓捏部,左夹体和右夹体处于转轴下方的部分为夹持部,上述扭力弹簧套在转轴上,扭力弹簧的一端与左夹体的抓捏部相接,扭力弹簧的另一端与右夹体的抓捏部相接;上述左夹体和右夹体的夹持部上分别设有弹性体。 Chinese Patent Document CN201939853U clip discloses a medical catheter or guide wire for which the structure is also more complex, the clip body includes a left and right clip body, shaft and torsion spring, the clip body of the left and right mutually rotatable collet mounted on the shaft, the left and right clamp collet body is located above the shaft portion of the handle portion, the clamping portion is located below the shaft portion of the body left and right chuck collet, the above-described torsion spring sleeved on the shaft, a torsion spring the left end of the handle portion of the clip body contact, the other end of the handle portion of the torsion spring is in contact with the right clamp member; an elastic member are provided on the holding portion of the left and right chuck collet body. 这些现有夹持装置中的夹持部位均为平板状或啮合齿状,这种结构直接夹持导丝, 如夹持过紧可能损伤导丝,尤其是微导丝,如夹持稍松有可能导致导丝从两块夹板的V形开口中弹出,造成导丝的污染。 These conventional clamping means clamping parts are plate-shaped or in toothed engagement, this configuration directly gripping the guidewire, such as guidewire may damage the tight clamping, especially micro guidewire as slightly loose clamping may lead wire is ejected from the opening of two V-shaped jaws, causing contamination of the guidewire. 并且现有技术中多数夹持装置仅是对导丝的夹持,虽然有些可应用于导管,但其夹持部的平板状或啮合齿状结构导致夹持较松则夹持效果不好,夹持过紧则有可能对导管造成损伤,严重者可压闭导管,影响手术操作,故对夹持的力度不容易控制,操作使用不方便。 Most of the prior art and the clamping device is only clamped to the guide wire, although some may be applied to catheters, or tabular but which engagement tooth holding portion holding structure results in a loose clamp is ineffective, holding the too tight may cause damage to the catheter, the catheter may be serious closing pressure, affects the operation, it is not easy to control the intensity of the clamping, the operation is inconvenient. 此外,以上现有夹持装置均无法直接湿润亲水导丝,其所夹持的导丝取出后多数均需在肝素生理盐水中再次湿润后才可再次应用。 Further, the above conventional clamping means are not directly wetted hydrophilic guidewire, after which it is sandwiched between the guide wire removed most of the required wetted again before re-application of heparin in saline. 因此,迫切需要一种能解决上述技术问题的全新夹持装置。 Therefore, the urgent need for a new clamping device can solve the above problems.
