Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a common bile duct radiography puncture needle with an extension tube for a laparoscope.
Background
In laparoscopic biliary tract operation, when a suspicious common bile duct has calculus, common bile duct radiography is required to determine whether the calculus exists in the common bile duct, so that whether the common bile duct needs to be cut open to perform calculus removal is judged. Meanwhile, the biliary tract can be imaged integrally after radiography, and an operator can clearly know the integral shape and trend of the biliary tract. If the patient has a history of operation and the abdominal cavity is seriously adhered, it is difficult to distinguish the blood vessel from the common bile duct before the common bile duct is cut. If the surgery cannot be accurately distinguished, the surgery is easy to cause mistaken injury. At present, a special radiography tube for a laparoscope common bile duct does not exist, and other pipelines are required to be used for replacing the radiography tube during radiography, so that a radiography puncture needle which can complete radiography and can distinguish the common bile duct by puncturing tissues is urgently needed at present.
SUMMERY OF THE UTILITY MODEL
The utility model provides a common bile duct radiography puncture needle with an extension tube for a laparoscope, aiming at the problems in the prior art.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the choledochoscope angiography puncture needle with the extension tube for the laparoscope comprises a connector, a connecting tube and a needle head, wherein a connecting part is arranged at one end of the connector, one end of the connecting tube is installed in the connecting part, the needle head is installed at the other end of the connector, a sealing plug is arranged at the other end of the connecting tube, the connecting tube is a flexible tube, and the connecting tube is made of transparent materials.
Preferably, a connecting piece is arranged between the connecting pipe and the sealing plug, and the connecting piece is made of soft plastic materials.
Preferably, the connecting pipe is provided with a graduated scale, and the graduated scale is provided with Arabic number numbers.
Preferably, the needle head is a No. 4 half, a No. 5 half or a No. 7 scalp needle, and the length of the needle head is 0.5-2 cm.
Preferably, the diameter of the connecting head is less than 4.5 mm.
Preferably, the length of the connecting pipe is 50-120cm, and the outer diameter of the connecting pipe is 1-3 mm.
Preferably, the connecting head is tapered.
The utility model has the beneficial effects that:
the utility model provides a common bile duct radiography puncture needle with an extension tube for a laparoscope, which comprises a connector, a connecting tube and a needle head, wherein one end of the connector is provided with a connecting part, one end of the connecting tube is arranged in the connecting part, the needle head is arranged at the other end of the connector, the other end of the connecting tube is provided with a sealing plug, the connecting tube is a hose, and is made of transparent materials.
