Abstract
The utility model relates to a luminous guide tube for medical use, which is composed of a transparent outer tube and light guide fiber. The light guide fiber is fixed in the transparent outer tube, and the luminous segment of the guide tube is composed of the endpoints of the light guide fiber. When the product is used in surgery, the cavity channel organ and the diseased tissue are easily distinguished, the operation can be conveniently, accurately and rapidly carried out by a clinician, the injury to the cavity channel organ and normal tissue are avoided.
Description
This utility model relates to a kind of medical luminous conduit.
(demonstration) that surgery has a lot of operations to relate to the tract organ recognized, so that protected and avoid damage in art.In order to solve this class problem, use in the section's of being out at present operation be can not be luminous conduit, be inserted in the tract organ and recognize by touching.Its shortcoming is time-consuming, inconvenient and not accurate enough, is difficult to grasp the degree of depth of incision outside the excision tract during pathological tissues, accomplishes that accurately removal lesion tissue should be thorough, can not damage normal structure again.When performing the operation around the tract organ, owing to be not direct demonstration, often need to touch traveling and the position of recognizing the tract organ, it is pretty troublesome often to perform the operation, and carefully also is difficult to avoid not accidentally injuring the tract organ even if accomplish.
The purpose of this utility model is to provide a kind of medical luminous conduit that can accurately recognize tract organ and pathological tissues in surgical operation.
This utility model is achieved in that it is made of transparent outer tube and optical fibers, and optical fibers is fixed in the transparent outer tube, and the conduit luminescence segment then is made up of the end points of optical fibers.
Below in conjunction with drawings and Examples this utility model is described in detail.
Fig. 1 is the structural representation of this utility model.
This utility model is made of transparent outer tube (1) and optical fibers (2), optical fibers (2) is fixed in the transparent outer tube (1), the conduit luminescence segment then is made up of the end points of optical fibers (2), can be made into luminous catheter, luminous ureteral catheter, luminous biliary catheter or surgical operation in view of the above with other medical luminous conduit.
Be used for keeping the urethra prostatectomy as luminous catheter, be inserted into urethra, when outside urethra, excising prostata tissue, see through the degree of depth of how much coming exactly grasp incision of urethral wall by light, when reaching urethral wall, can see the light that sees through, to guarantee thoroughly to excise prostata tissue and don't damage urethra, very convenient during operation.
Luminous ureteral catheter is used for abdominal operation or operation on ureter, is inserted into to make it become the pipeline of a light in the ureter and clearly illustrate out, is very easy to find or seeks ureter in the art.
Luminous biliary catheter is used for the recognition of hepatobiliary surgery biliary tract, when appearing with incision as stones in intrahepatic bile duct, need distinguish mutually with blood vessel in the liver, can not damage blood vessel in the liver when cutting bile duct.
This utility model is used for surgical operation, is easy to tract organ and pathological tissues difference are come, and makes things convenient for the clinician to undergo surgery accurately and rapidly, avoids damaging tract organ and normal structure.
Claims (1)
1. medical luminous conduit, it is characterized in that: it is made of transparent outer tube and optical fibers, and optical fibers is fixed in the transparent outer tube, and the conduit luminescence segment then is made up of the end points of optical fibers.
