1. 1. 一种医用发光导管,其特征在于:它由透明外管与光导纤维构成,光导纤维固定在透明外管内,导管发光段则由光导纤维之端点所组成。 A medical emitting catheter, characterized in that: it is made of a transparent outer tube constituting the optical fiber, the optical fiber is fixed in a transparent outer tube, by the end of the optical fiber conduit of the light-emitting section composed.
Description  translated from Chinese
医用发光导管 Medical luminous catheter

本实用新型涉及一种医用发光导管。 The utility model relates to a light-emitting medical catheters.

外科有很多手术涉及到腔道器官的(显示)辩认,以便在术中加以保护和避免损伤。 There are a lot of surgery involves surgical cavity organs (display) identification, in order to be protected and to avoid injury during surgery. 为了解决这类问题,目前在外科手术中使用的是不能发光的导管,将其插入腔道器官内通过触摸来辨认。 To solve this problem, currently used in surgery are not light conduit, will be identified by touching its insertion cavity organs. 其缺点为费时、不方便和不够准确,在切除腔道外病变组织时很难掌握好切开的深度,精确地做到切除病变组织既要彻底,又不能损伤正常组织。 The disadvantage is time-consuming, inconvenient and inaccurate, it is difficult to grasp the depth of a good cut at the resection cavity outside the lesion, and precise removal of diseased tissue is necessary to do a thorough, they can not damage normal tissue. 在腔道器官周围手术时,由于不是直接显示,往往需要触摸辩认腔道器官的走行和位置,手术时常很麻烦,即便是做到小心,也难以避免不误伤腔道器官。 At around the cavity organs surgery, because it is not directly show that often require touch recognizable organ cavity Traveling and location, surgery is often very troublesome, even if done carefully, it is difficult to avoid the cavity organs not fire.

本实用新型的目的在于提供一种能在外科手术中准确辩认腔道器官与病变组织的医用发光导管。 The utility model aims to provide an accurate recognizable in surgery cavity organs and diseased tissue luminous medical catheters.

本实用新型是这样实现的,它由透明外管与光导纤维构成,光导纤维固定在透明外管内,导管发光段则由光导纤维之端点所组成。 The utility model is achieved in that an outer tube and an optical fiber constituted by a transparent, optical fiber secured within a transparent outer tube, the light emitting section by the end of the optical fiber conduit of the composition.

下面结合附图和实施例对本实用新型作详细描述。 The accompanying drawings and the following detailed description of embodiments of the utility model for.

图1为本实用新型之结构示意图。 Figure 1 is a schematic diagram of the structure of the utility model.

本实用新型由透明外管(1)与光导纤维(2)构成,光导纤维(2)固定在透明外管(1)内,导管发光段则由光导纤维(2)之端点所组成,据此可制成发光导尿管、发光输尿管导管、发光胆道导管或外科手术用别的医用发光导管。 The utility model is made of a transparent outer tube (1) and the optical fiber (2) constitute, optical fiber (2) fixed in a transparent outer tube (1), the catheter from the light-emitting optical fiber segment (2) is composed of endpoints, accordingly the catheter can be made luminous, light ureteral catheter, luminous biliary catheter or other medical surgical luminous catheters.

如发光导尿管用于保留尿道前列腺切除术中,将其插入尿道,在沿尿道外切除前列腺组织时,透过尿道壁通过光亮的多少来准确地掌握切开的深度,当达到尿道壁时可见到透过的光亮,以保证彻底切除前列腺组织而又不损伤尿道,手术时很方便。 The light-emitting catheter for urinary retention prostatectomy, which was inserted into the urethra at the external urethral resection of prostate tissue along through the urethral wall by the light of how to accurately grasp the depth of cut, when it reaches the urethra wall can be seen Through the light, in order to ensure complete removal of the prostate tissue without damage to the urethra, very convenient operation.

发光输尿管导管用于腹部手术或输尿管手术中,将其插入输尿管内使其成为一条光亮的管道而清楚地显示出来,术中很容易发现或寻找输尿管。 Luminous ureteral catheter or ureter surgery for abdominal surgery, and will make it into the ureter become the conduit of a bright and clearly displayed, surgery is easy to find or search for the ureter.

发光胆道导管用于肝胆外科手术中胆道的辩认,如肝内胆管显露与切开时,需要与肝内血管相区别,切开胆管时不会损伤肝内血管。 Luminous biliary duct hepatobiliary surgery for biliary recognizable, such as intrahepatic bile duct revealed with the cut, you need to distinguish intrahepatic vessels, blood vessels without damaging the liver bile duct incision.

本实用新型用于外科手术中,很容易将腔道器官与病变组织区别开来,方便临床医生准确、快速地进行手术,避免损伤腔道器官及正常组织。 The utility model is used in surgery, it is easy to distinguish luminal organs and tissue lesions open to facilitate clinicians to accurately and quickly perform the surgery, to avoid damage to normal tissues and organs cavity.
