In the present invention, it is the accuracy for further ensuring that puncture, is arranged preferably on the outer surface of outer tube 1 and carves
Degree further increases the accuracy of puncture when puncturing.
Further, in the present invention, inner tube 2 and the material of outer tube 1 are preferably metal, to ensure that puncture process is suitable
Benefit carries out.
This kind of visual puncturing needle can carry out real-time monitoring to puncture process, can quickly and accurately complete puncture process, avoid
Repeated puncture mitigates the pain of patient.
After puncturing successfully, inner tube 2 can be extracted from outer tube 1 together with endoscope, be penetrated using the cavity of outer tube 1
Seal wire moves back except outer tube 1 when seal wire is inserted in place, seal wire is stayed in human body, at this point, operation puncturing is completed.
The utility model additionally provides a kind of visual puncturing needle, an inner tube 2 is only included, to substantially reduce puncture needle
Outer diameter, mitigate the pain of patient, simultaneously because puncture caused by wound it is smaller, can substantially shorten the recovery time of patient.
Specifically, it is made of due to puncture needle an inner tube 2, punctures human skin for the ease of puncture needle, preferably exist
The tip 23 of the insertion end setting puncture of inner tube 2, meanwhile, the material of inner tube 2 is preferably hard metal or by the inner wall of inner tube 2
It thickeies, increases the hardness of inner tube 2, to ensure that inner tube 2 patient's body can be successfully inserted into；Inner tube 2 is hollow tubular structure,
It is equipped with cavity in the middle part of inner tube 2, can be inserted into endoscope in cavity, it, can be to puncturing through using endoscope when being punctured to patient
Cheng Jinhang real time monitoring, is properly inserted in position, prevents from being inserted into too deep or be inserted into not in place.
Further, the non-intrusive end of inner tube 2 is connected with three-way interface, and three-way interface first end and the non-of inner tube 2 insert
Enter end to be connected, the second end of three-way interface is endoscope import, and the third end of three-way interface is water inlet 22, passes through water inlet
22 can into inner tube 2 saline injection, the tissue before endoscope lens or dirt will be blocked using the impact force of water flow
Object is washed open, and the relatively clear visual field has been obtained.
Further, in order to ensure keeping opposing stationary between endoscope and inner tube 2, preferably three in puncture process
It connects and fixed device is set in the second end of mouth, anti-hydropexis plug can be connected in the inlet end portion of inner tube, prevent when endoscope passes through
When hydropexis plug is inserted into suitable position of the inner tube 2 to outlet, anti-hydropexis plug is screwed, thus fixed endoscope.
When it is implemented, inner tube 2 is inserted into outer tube 1, then endoscope is inserted into inner tube 2, screwing female Luer will
Inner tube 2 is fixedly connected with outer tube 1, that is, completes the assembly of visual puncturing needle.Water inlet 22 can be utilized to patient's body when puncturing
Interior saline injection will be blocked in the object before camera lens and wash open, obtained the more clearly visible visual field.After puncturing in place, it can incite somebody to action
Endoscope takes out, and is inserted into seal wire to establish guiding channel and facilitates the progress of subsequent procedures.Predetermined position is reached in puncture needle
Afterwards, after endoscope being extracted, it can be put into seal wire by the inner cavity of inner tube 2, remove inner tube 2, seal wire is stayed in human body, perform the operation
It punctures and completes.
