The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

As shown in fig. 1 to 3, the present embodiment provides a guide sheath for a falloposcopy, which includes an insertion sleeve 1, a connection insert 2, a guide tube 3 and a locking module 4, which are sequentially communicated with each other through a pipeline, wherein a limiting ring 5 is disposed on the surface of the connection insert 2, a tee pipeline 21 is disposed in the connection insert 2, the tee pipeline 21 is communicated with an insertion opening 6 and two guide openings 7, the insertion opening 6 is communicated with the insertion sleeve 1, the two guide openings 7 are respectively communicated with the guide tube 3, and the locking module 4 is disposed at the end of the guide tube 3.

The insertion tube 1 is generally made of a soft plastic material, so that the insertion tube 1 can be bent according to the angle difference between the vaginal opening and the tubal outlet, and can be smoothly inserted into the tubal isthmus with a bent shape. The internal channel provided by the guide sheath prevents the main body of the oviduct lens from directly contacting with a patient, and reduces the cleaning requirement of the oviduct lens. The locking module 4 can fix the oviduct lens on the guide sheath, thereby facilitating the positioning. The limiting ring 5 can prevent the insertion sleeve 1 from being excessively inserted into the body of the patient, and misoperation is avoided. Due to the design of the three-way pipeline 21, the guiding sheath can hold the oviduct lens and can convey the medicine to the oviduct through the spare guiding tube 3, thereby facilitating the observation and diagnosis as well as the treatment.

The front end of the insertion sleeve 1 is provided with a conical insertion head 8, and the pipeline of the conical insertion head 8 is communicated with the insertion sleeve 1. The tapered insertion head 8 design facilitates insertion of the forward end of the insertion sleeve 1 into the tubal ostium.

The three-way pipe 21 comprises an insertion end 211 and two guide ends 212 which are communicated with each other, wherein the insertion end 211 is communicated with the insertion port 6 and is opened forwards, and the guide ends 212 are communicated with the guide ports 7 and are opened backwards. The input end and the output end of the three-way pipe 21 are symmetrically arranged, so that the directions can be conveniently distinguished during assembly.

The insertion sleeve 1 is sleeved in the insertion end 211, and the guide tube 3 is sleeved in the guide end 212. The insertion sleeve 1 sleeved in the insertion end 211 and the guide tube 3 sleeved in the guide end 212 are stably connected and are not easy to fall off.

A medical glue layer is filled between the insertion sleeve 1 and the insertion end 211 and between the guide tube 3 and the guide end 212. The medical glue layer (not shown) improves the structural connection stability and the air tightness of the internal pipeline.

The limiting ring 5 is correspondingly arranged on the outer wall of the insertion end 211. The stop ring 5 protruding from the connecting insert 2 prevents over-insertion of the guide sheath.

The locking module 4 comprises an airtight sleeve seat 41, the tail end of the guide tube 3 is sleeved in the airtight sleeve seat 41, the tail end air path of the airtight sleeve seat 41 is communicated with a locking connector 43, and the locking connector 43 is a luer male connector. The tail end of the guide pipe 3 is matched and sleeved with the airtight sleeve seat 41, so that the sealing performance of an internal pipeline is ensured; the luer male connector has strong universality, can be butted and fixed with a matched luer female connector, and can be arranged on a matched oviduct lens, so that the positioning and the assembly and disassembly of the oviduct lens are convenient.

The locking joint 43 is communicated with the airtight sleeve seat 41 through a funnel-shaped guide pipe 42. The funnel-shaped guide pipe 42 has a guiding and orienting function, so that the smoothness of the object reaching the airtight sleeve seat 41 after entering the locking joint 43 can be improved, and the object is prevented from being clamped in the locking module 4.

The insertion sleeve 1, the connecting insert 2, the guide tube 3 and the locking module 4 are all made of medical grade plastics. The whole guide sheath is made of medical grade plastics, so that the guide sheath is light in weight, high in cleanliness and low in cost, can be used as a disposable consumable, and simplifies the cleaning operation of equipment.

The foregoing is a more detailed description of the utility model than is specifically described in connection with the preferred embodiments, and it is not intended to limit the utility model to the particular forms disclosed, since all equivalent variations and modifications as fall within the scope of the appended claims are intended to be embraced therein.
