Description

一种内窥镜下取物网篮及其制备方法 An endoscope and the basket was prepared Methods

技术领域 FIELD

[0001]本发明涉及医疗器械领域,特别是一种内窥镜取物网篮及其制备方法。 [0001] The present invention relates to the field of medical devices, and in particular a method for preparing the basket was taken endoscope.

背景技术 Background technique

[0002]内窥镜取物网篮均由圈套和网袋连接而成,它应用与体内,很可能接触血液,所以圈套和网袋连接时非常忌讳胶水。 [0002] The endoscope and the snare extract by baskets connected in net bags, it is applied, it may come into contact with the blood in vivo, it is very taboo glue trap and net bag when connected. 鉴于此,现有的内窥镜取物网篮均采用将圈套和网袋用线扎的形式连接在一起,为了将圈套和网袋连接的更加牢固,需要将非常细的薄膜丝从圈套中间多次穿入,缠绕,导致扎线的难度非常高,效率较低,生产成本也极高。 In view of this, conventional endoscope extract baskets are used and are connected together snare mesh bag with a wire form, in order to trap and net bag more firmly attached, you need to be very thin intermediate film from the snare wire penetration times, winding, resulting in a very high degree of difficulty of the binding thread, less efficient, high production costs.

发明内容 SUMMARY

[0003]本发明为了克服上述技术问题的不足,提供了一种内窥镜取物网篮及其制备方法,可以完全解决上述技术问题。 [0003] The present invention is to overcome the shortcomings of the above technical problems, there is provided an endoscope basket extract and its preparation method, the above problems can be completely solved.

[0004]解决上述技术问题的技术方案如下: [0004] The technical problem to solve the above technical solution as follows:

[0005] —种内窥镜取物网篮,包括圈套和网袋,网袋与圈套采用粘接方式连接。 [0005] - seed extract endoscope basket, and snare comprising a mesh bag, the mesh bag snare connected using an adhesive.

[0006]所述的网袋与圈套通过液态聚氨酯高温固化粘接,液态聚氨酯即为液态的聚氨酯预聚体。 [0006] The mesh bag and the liquid polyurethane through the snare temperature curing adhesive, that is, liquid polyurethane liquid polyurethane prepolymer.

[0007]所述的圈套包括第一圆弧部、第二圆弧部和过渡部,所述的第一圆弧部、第二圆弧部和过渡部一体折弯成型,所述的过渡部位于第一圆弧部和第二圆弧部的前端,所述的第一圆弧部和第二圆弧部的末端通过激光焊接与连接管的一端连接,连接管另一端与操纵用镍钛丝焊接连接,所述的过渡部包括第一连接部和第二连接部,所述的第一连接部的一端与第一圆弧部通过第一圆弧连接,所述的第二连接部的一端与第二圆弧部通过第二圆弧连接,所述的第一连接部的另一端和第二连接部的另一端通过第三圆弧连接。 [0007] The trap comprises a first arcuate portion, the second arcuate portion and a transition portion, said first arcuate portion, the second arcuate portion and a transition portion integrally molded bending, the transition portion a first arcuate portion at the front end portion and the second arc, said first arcuate end portion and a second arcuate portion connected to the other end of the pipe is connected to the actuating NiTi laser welding one end of the connection pipe wire welded connection, the transition portion comprises a first connection portion and the second connecting portion, a second connecting portion connected to one end of the first arcuate portion connected to the first portion by a first circular arc, of the One end of the second arcuate portion is connected by a second arc, the other end portion of the first connector and the other end of the second connecting portion are connected by a third circular arc.

[0008]所述的圈套由钢丝绳一体折弯或高温定型而成。 [0008] the snare wire rope or bent integrally from high temperature setting.

[0009] 所述的钢丝绳由5〜10根直径为0.05〜0.2mm的钢丝缠绕而成。 [0009] the wire rope by a root diameter of 5 to 10 wire wound from 0.05~0.2mm.

[0010] 所述的钢丝为304不锈钢丝或316不锈钢丝。 [0010] The wire 316 is 304 stainless steel wire or stainless steel wire.

[0011]所述的网袋为丝网或薄膜。 [0011] The screen or mesh bag of a film.

[0012]本发明还提供了这种内窥镜取物网篮的制备方法,包括以下步骤: [0012] The present invention further provides a method for preparing such an endoscope extract basket, comprising the steps of:

[0013]将钢丝绳折弯或高温定型成圈套,与连接管焊接一体,然后将圈套与网袋按要求放置于模具内,再向模具内注入液态聚氨酯,将模具连同产品置入高温环境使得液态聚氨酯固化,温度采用75〜130°C,固化30〜60分钟后取出冷却至常温即完成圈套和网袋的粘接。 [0013] The rope is bent or shaped into a trap temperature, and the connecting pipe are integrally welded with the mesh bag and then the trap is placed in the mold as required, again within the polyurethane liquid injected into the mold, the mold was placed in a high temperature environment such that together with the liquid product polyurethane curing, a temperature of 75~130 ° C, remove the solidified after cooling to room temperature 30~60 minutes to complete an adhesive trap and a net bag.

[0014]本发明的另一个目的是提供了一种液态聚氨酯预聚体在医疗器械领域的应用,液态聚氨酯预聚体可以以粘接剂的形式应用于医疗器械领域中。 [0014] Another object of the present invention is to provide the use of a liquid polyurethane prepolymer in the field of medical devices, liquid polyurethane prepolymer in the form of an adhesive may be applied to the field of medical instruments.

[0015]液态聚氨酯预聚体的粘接原理不同于常规意义上的聚氨酯类胶黏剂,尤其是湿气固化类聚氨酯胶黏剂,这类聚氨酯胶黏剂也是利用聚氨酯本身的粘性达到粘接的,区别在于聚氨酯类胶黏是将加温到80°C的聚氨酯类胶黏剂涂覆到产品上,通过与空气中的水分反应固化从而达到粘接的目的,如果空气过分干燥,则不能迅速固化,其使用前是固态存在的,加热至80°C后才能软化;而液态聚氨酯预聚体则正好相反,是将其注入至模具中后加温到75〜130°C固化,冷却过程中环境需十分干燥,不可接触水分,其使用前是液态的。 [0015] The principle of liquid adhesive polyurethane prepolymer differs from the polyurethane-based adhesive in a conventional sense, in particular, moisture-curable type polyurethane adhesive, such polyurethane adhesive using an adhesive is a polyurethane adhesive itself achieves the difference is that the polyurethane-based adhesive bonding to the urethane-based adhesive was warmed to 80 ° C to coat the product and by the moisture in the air so as to achieve the purpose of curing reaction of the adhesive, if air is too dry, it can not rapid solidification, prior to its use is a solid present, can soften and heated to 80 ° C; the liquid polyurethane prepolymer is the opposite, it is injected into the mold heated to 75~130 ° C curing, cooling in very dry environments need not be exposed to moisture prior to its use is liquid. 液态聚氨酯通常的用途是用作浇注护套或保护层用途,在医疗上的常规用途有人造血管、人造心脏瓣膜之类成型产品,一般不作为胶黏剂用途。 Liquid polyurethane is used as the casting is usually uses a sheath or protective layer purpose, there are artificial blood vessels, artificial heart valve or the like on the molded product in a conventional medical use, as the adhesive does not generally use.

[0016]本发明将液态聚氨酯预聚体应用到医疗器械的粘接作用中,制备了一种安全无毒的内窥镜取物网篮,具有较高的强度,足以满足内窥镜取物应用。 [0016] The present invention is a liquid polyurethane prepolymer is applied to the adhesive effect of a medical device, an endoscope, a safe non-toxic extract prepared basket, having high strength, sufficient to meet the endoscope extract application. 生产步骤简单,成本较低,且生产效率极高。 Production process is simple, low cost and high production efficiency. 整个过程中不使用任何溶剂或添加剂,非常安全。 Without using any solvent or additive throughout the process, very safe.
