[ detailed description ] embodiments

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 efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a micro-channel visible puncturing and expanding integrated kit 100. The ultramicrochannel visual puncture and dilation integrated kit 100 comprises a puncture needle 10 and a dilation sheath 20 for movably accommodating the puncture needle 10. In particular, in this embodiment, the ultramicro-channel visual puncture dilation integrated set 100 further comprises a three-way structure 30 connected to the puncture needle. The puncture needle 10 is made of hard metal, and the material of the expansion sheath 20 is not limited by the utility model, and can be made of any one of metal material or medical polyurethane material.

The puncture needle 10 includes an insertion end 11, a non-insertion end 12 disposed opposite from the insertion end 11, and a hollow cavity 13 having a hollow tubular structure in the middle. The endoscope can be inserted into the cavity 13, when a patient is punctured, the puncturing process can be monitored in real time by using the endoscope, the endoscope can be accurately inserted in place, and the phenomenon that the endoscope is inserted too deeply or is not inserted in place is avoided. The insertion end 11 has a puncture tip, and the puncture needle 10 has a tip extending out of the dilating sheath 20. In particular, in order to facilitate flexible puncturing, the insertion end 12 extends beyond the dilating sheath 20 by a distance of 2-5 mm.

The non-insertion end 12 is provided with an operating passage opening communicating with the cavity 13. Preferably, in this embodiment, the operation passage port is implemented by a three-way structure. Specifically, in this embodiment, the non-insertion end 12 is provided with a first connecting portion 121 and a needle holder 122, the needle holder 122 is provided with a second connecting portion 123, and the first connecting portion 121 and the second connecting portion 123 can be connected in a matching manner. Specifically, the first connection portion 121 and the second connection portion 123 may be connected by a luer fitting in a matching manner. The three-way structure 30 is disposed at the rear end of the second connection portion 123. Because the organ tissues, blood or other dirt of the human body can possibly shield the lens of the endoscope in the puncture process to influence the visual field, the cavity 13 can be used for injecting physiological saline into the human body, and the impact force of the water flow is used for flushing away the tissues or the dirt of the human body to obtain a clearer visual field. Thus, one inlet of the three-way structure 30 is a water inlet 31, and the other inlet of the three-way structure 30 is provided with an operation passage opening 32. The operation passage port 32 can be inserted into an endoscope to observe the puncture process in real time.
