Abstract
The utility model discloses an anti-separation biliary drainage tube. The anti-separation biliary drainage tube comprises a tube body with a drainage hole, and is characterized in that a balloon is fixed at the front end of the tube body; the tube body is a dual-cavity tube body comprising sealed longitudinal channels I and II; the longitudinal channel I is communicated with the balloon; the longitudinal channel II is communicated with the drainage hole; a one-way valve is arranged in the longitudinal channel I; the drainage hole comprises an opening at the front end part of the tube body and a side hole in the tube wall; the inlet end of the longitudinal channel I is provided with a filling nozzle; the outlet end of the longitudinal channel II is provided with a drainage nozzle; the front end of the tube body is provided with an annular interlayer with air, so that the tube body can be clearly demarcated from biliary ducts and surrounding tissues on an ultrasonic screen, and doctors can be helped to judge the insertion situation of the drainage tube; and the annular interlayer is convenient to process and manufacture, only a stainless steel round tube with a diameter slightly greater or smaller than that of the tube body of the anti-separation biliary drainage tube needs to be connected to the front end of the anti-separation biliary drainage tube, and the cost is lower.
Description
Technical field
This utility model relates to a kind of liver and gall road drainage tube, and particularly a kind of anticreep percutaneous is drainage tube through the liver and gall road.
Background technology
The percutaneous transhepatic cholangiography and drainage art is mainly used in the pernicious obstruction of biliary tract that late tumor causes; Preparation before the drain of appeasing property of row biliary tract, degree of depth jaundice patient's the art, acute biliary infection; Like acute obstructive suppurative cholangitis; Row emergency case biliary tract decompression drainage transfers emergency operation to choose date for operation or gets stone etc. through the capable chemotherapy of drainage tube, radiotherapy, lithodialysis, cytolgical examination and the capable fiber endoscopy of percutaneous.
In the prior art, the puncture drainage device comprises puncture needle, seal wire, sinus tract dilator and drainage tube to the percutaneous of use through the liver and gall road, drain piping list chamber latex tubing wherein, and front end has opening and side opening.Clinical manipulation penetrates the puncture needle percutaneous earlier and treats that the drain bile duct props up under ultrasonic or X-ray guiding through liver, after extracting bile out or injecting contrast agent affirmation position; Insert seal wire to treating the drain bile duct through the puncture needle heart; Take out puncture needle, after expanding along seal wire with the sinus tract dilator, drainage tube inserted through seal wire treat the drain bile duct; Take out seal wire, at last drainage tube is met to close to be fixed on skin penetrating point place.Because drainage tube is a light pipe, occurs taking off the pipe phenomenon after the puncture easily.For anti-anti-avulsion pipe, need meet at skin penetrating point place during operation and close fixingly, be prone to cause local inflammation, redness, pain, and fixed effect is bad, drainage tube is prone to slippage, causes the drain failure, needs to perform the operation again, lowers efficiency.There is the people that existing drainage tube is improved for this reason; As State Intellectual Property Office on October 15th, 2008 disclosed by Zheng Shuguo design, the patent No. is 200720188089.4, name is called the utility model patent of anticreep percutaneous through liver and gall road drainage tube; This technical scheme comprises the body that has draining hole; The body front end is set with capsule, and body is the two-chamber body that comprises vertical passage I and vertical passage II, seals between vertical passage I and the vertical passage II; Vertical passage I communicates with capsule, and vertical passage II communicates with draining hole; Be provided with check valve in the vertical passage I.Draining hole comprises that opening and one of body leading section are with the upper tube wall side opening; Capsule and body are processed one, are enclosed within the body cylindrical; Vertical passage I entrance point is provided with coupler, and the vertical passage II port of export is provided with the drain mouth; This drainage tube body front end is set with capsule, inflation or liquid in the capsule of puncture back, and capsule is used to prevent that drainage tube from coming off after rising greatly; Overcome the past percutaneous through existing defective of liver puncture biliary tract drain and deficiency; Can not only prevent the drainage tube slippage, and the skin penetrating hole need not meet and close fixingly, avoid because the repeatedly operation that causes of fixation problem; Eliminate the phenomenon that causes local inflammation, redness, pain in skin penetrating point place's sutured, improved operation efficient and therapeutic effect.But because it is ultrasonic down very not clear with bile duct and surrounding tissue boundary, especially for the doctor physician of often not seeing ultrasonic image, it be indispensable please ultrasonic doctor holding a consultation.Therefore be starved of a kind of very easily ultrasonic down with bile duct and the surrounding tissue biliary stent clearly of demarcating, judge the insertion situation of drainage tube with the help doctor.
Summary of the invention
The purpose of this utility model provides a kind of anticreep biliary stent, to solve since the general drainage pipe ultrasonic down with liver and surrounding tissue demarcate very not clear, let the doctor feel unhandy problem,
This utility model for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of anticreep biliary stent comprises the body that has draining hole, and the body front end is set with capsule; Body is the two-chamber body that comprises vertical passage I and vertical passage II; Seal between vertical passage I and the vertical passage II, vertical passage I communicates with capsule, and vertical passage II communicates with draining hole; Be provided with check valve in the vertical passage I, draining hole comprises the opening and the tube wall side opening of body leading section; Vertical passage I entrance point is provided with coupler, and the vertical passage II port of export is provided with the drain mouth, it is characterized in that: it is characterized in that: the front end of described body is provided with the annular gap that contains air.
Utilize the operation process of this utility model: implementing clinical percutaneous through the liver and gall road during drain; At first under the guiding of B ultrasonic or lonizing radiation, puncture needle penetrated and treat the drain bile duct; Take out nook closing member, seal wire inserted through the puncture needle pin heart treat the drain bile duct, expand sinus tract with the sinus tract dilator along seal wire after; Drainage tube inserted through seal wire treat the drain bile duct; Owing to ultrasonic air is had intensive reflexive, it is clear with bile duct and surrounding tissue boundary on the ultrasonic machine fluorescent screen to make this utility model anticreep biliary stent front end contain the annular gap of air, can help the doctor to judge the insertion situation of drainage tube; Take out seal wire, inflate in capsule through the coupler of capsule pipe, the drain mouth connects drainage bag, end operation.
The anticreep biliary stent of this utility model, the front end of its body is provided with the annular gap that contains air, can make it clear with bile duct and surrounding tissue boundary on the ultrasonic machine fluorescent screen, can help the doctor to judge the insertion situation of drainage tube; And this annular gap processing and fabricating is convenient, only needs one section diameter of intercepting stainless pipe big or slightly littler slightly than the diameter of anticreep biliary stent body to be connected to the front end position of anticreep biliary stent body, and cost is lower.
