Abstract

The utility model belongs to the field of a medical appliance and relates to a cystic duct cholangiography tube capable of being used for the laparoscopic surgery. The cystic duct cholangiography tube comprises a guide head, drug injection lateral holes and a syringe spigot. The guide head is arranged at the front end of the cholangiography tube. The side wall close to the head end is provided with a plurality of drug injection lateral holes. The tail end of the cholangiography tube is provided with the syringe spigot. The cystic duct cholangiography tube is matched with a puncture needle and a syringe. The trial result shows that the cystic duct cholangiography tube is obviously favorable for positioning the surgical position, is convenient for a doctor to carry out an operation, reduces unnecessary bile duct negative exploration, can be convenient to distinguish the cystic duct to carry out anatomy, avoids damaging the bile duct, improves quality and safety of laparoscopic cholecystectomy, has the advantage of low cost and can be widely used for the celiac cystic duct surgery.

Description

Through cystic duct cholangiography pipe

Technical field

This utility model belongs to medical instruments field, relates to the cholangiography device, be specifically related to a kind of can be used for laparoscopic surgery through cystic duct cholangiography pipe.

Background technology

At present, the cholecystectomy under Clinical Surgery's row peritoneoscope has become the first-selected art formula of gallbladder removal, but carry out cholangiography under peritoneoscope certain difficulty is arranged still, and its reason mainly is to lack necessary apparatus to assist.Prior art method commonly used is, under peritoneoscope epidural catheter inserted the expert cholangiography of common bile duct through cystic duct, but epidural catheter costs an arm and a leg, and increased patient's medical burden.

It is a kind of undamaged and cheap to biliary tract that clinical practice show to be badly in need of is wanted, be convenient to promote the use of through cystic duct cholangiography pipe unit.

Summary of the invention

The purpose of this utility model is for overcoming the deficiencies in the prior art and defective, a kind of cholangiography device is provided, especially a kind of can be used for laparoscopic surgery through cystic duct cholangiography pipe.

This utility model is through the risk of cystic duct cholangiography pipe not damaged biliary tract, and cheap, is convenient to promote the use of.

This utility model also provides and described corollary equipment through cystic duct cholangiography pipe, generally includes puncture needle and syringe, and 76% cardiografin is housed in the syringe.

Particularly, this utility model is a kind of through cystic duct cholangiography pipe, comprises seeker (1), injection side opening (2) and syringe socket (3); Wherein, describedly establish seeker (1) through cystic duct cholangiography pipe front end, the sidewall of near head end is provided with a plurality of injection side openings (2), and end is provided with syringe socket (3).

In this utility model, be hollow tubular structure, certain rigidity is arranged, can not closed by titanium folder folder through cystic duct cholangiography pipe; Described radiography pipe adopts biliary stent material preparation well known in the art.

In this utility model, be the blunt type of circle, can not damage biliary tract when inserting cystic duct through the seeker (1) of cystic duct cholangiography pipe front end.

In this utility model, the sidewall of described radiography pipe near head end is provided with a plurality of injection side openings (2), and contrast agent injects biliary tract through this injection side opening (2).

In this utility model, the described syringe socket (3) that is located at radiography pipe end connects syringe.

In this utility model, be 200-1000mm through the length of cystic duct cholangiography pipe, preferred length is 600mm, and its external diameter is 1-5mm, and preferred external diameter is 1mm.

In this utility model, its front end lateral wall of described radiography pipe is provided with scale, is convenient to show the degree of depth of insertion, has the preferred 40mm of length range of scale part.

This utility model also provides and described corollary equipment through cystic duct cholangiography pipe, comprises puncture needle and syringe; Described puncture needle can provide passage for described cholangiography pipe enters the abdominal cavity, and the internal diameter of puncture needle is 1mm usually, and length is 100mm; Described syringe capacity is generally 20ml, and 76% cardiografin of 15ml is housed, and uses for radiography in the operation.

When clinical operation uses, under peritoneoscope monitored, described puncture needle penetrated stomach wall, with the seeker (1) of herbal classic cystic duct cholangiography pipe by this puncture needle, enter the abdominal cavity, then herbal classic cystic duct cholangiography pipe is inserted cystic duct, the scale by the lateral wall mark is provided with shows the degree of depth of inserting, when being inserted into desired depth or meeting obstructions, decide herbal classic cystic duct cholangiography pipe with the titanium clamping, inject contrast agent then after, implement laparoscopic cholecystectomy.

This utility model obviously helps the operative site location.Show that through result on trial this cholangiography tube side is doctor's operation technique just, reduces unnecessary bile duct feminine gender and detects, can conveniently distinguish biliary tract and dissect, avoid bile duct injury, improved the quality and the safety of laparoscopic cholecystectomy.And cheap, can be widely used in the abdominal cavity operation on biliary tract.

For the ease of understanding, below will describe in detail this utility model by concrete drawings and Examples.It needs to be noted that specific embodiments and the drawings only are in order to illustrate, obviously those skilled in the art can illustrate according to this paper, and this utility model is carried out various corrections or change, and these corrections and changing also will be included within this patent scope.

Specific embodiment

Embodiment 1

As shown in Figure 1, this utility model is a kind of through cystic duct cholangiography pipe, comprises seeker (1), injection side opening (2) and syringe socket (3); Wherein, describedly establish seeker (1) through cystic duct cholangiography pipe front end, the sidewall of near head end is provided with a plurality of injection side openings (2), and end is provided with syringe socket (3).

In this utility model, be hollow tubular structure, certain rigidity is arranged, can not closed by titanium folder folder through cystic duct cholangiography pipe.The seeker of front end (1) is the blunt type of circle, can not damage biliary tract when inserting cystic duct.The sidewall of near head end is provided with a plurality of injection side openings (2), and contrast agent injects biliary tract through this injection side opening (2).The described syringe socket (3) that is located at radiography pipe end connects syringe.
