Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment: a disposable extension tube for liver and gall negative pressure suction comprises a negative pressure fixing tube 1, one side of the negative pressure fixing tube 1 is provided with an extension guide tube 2, the surfaces of the negative pressure fixing tube 1 and the extension guide tube 2 are respectively fixedly sleeved with a first threaded tube 3 and a second threaded tube 4, the surface of the first threaded tube 3 is provided with a fixing sleeve 5, the inside of the fixing sleeve 5 is in threaded connection with the surfaces of the first threaded tube 3 and the second threaded tube 4, one end of the extension guide tube 2 with a clamping column 7 is inserted into a clamping groove 8 on the negative pressure fixing tube 1, the negative pressure fixing tube 1 can be attached to the extension guide tube 2 after the clamping column 7 is inserted to the bottom, then the fixing sleeve 5 on the first threaded tube 3 is rotated by hand, the fixing sleeve 5 can be slowly covered on the second threaded tube 4 along the first threaded tube 3 during rotation, good sealing performance can be achieved, firm connection and simple operation are achieved, the condition of looseness is avoided, and the puncture safety and success rate are improved.
