Example 1

As shown in fig. 1 to fig. 2, the present embodiment provides a puncture sheath dedicated for a choledochoscope, which includes a hard tube portion 20 and a soft tube portion 30, wherein the hard tube portion 20 and the soft tube portion 30 both include a puncture device inner core 12, the soft tube portion 30 is disposed at one end close to the tip of the puncture device inner core 12, one end of the hard tube portion 20 is fixedly connected to the choledochoscope body 11, and the other end is fixedly connected to one end of the soft tube portion 30 away from the tip of the puncture device inner core 12; the outside of the hard tube part 20 is provided with a limiting device 40.

In this embodiment, the limiting device 40 includes a limiting suction cup 41, the limiting suction cup 41 penetrates through the hard tube portion 20, and the disc surface of the limiting suction cup 41 is perpendicular to the axial direction of the hard tube portion 20. The limiting suction cup 41 can be adsorbed on the surface of the skin, so that the insertion depth of the puncture outfit is limited, and the condition that a doctor is inserted too deeply to hurt the organs of a patient when the puncture outfit is used is avoided. Specifically, the limiting suction cup 41 is made of elastic sterile materials, is comfortable to touch when being in contact with the skin of a patient, and cannot bring infection risks.

In this embodiment, stop device 40 still includes the supporting seat, supporting seat and 41 fixed connection of spacing sucking disc, and the supporting seat includes retainer plate 42 and bracing piece 43, the one end and the retainer plate 42 fixed connection of bracing piece 43, the other end and 41 fixed connection of spacing sucking disc. The supporting seat can provide more stable support for limiting suction cup 41, and retainer plate 42 can be fixed whole stop device 40 in the hard tube portion 20 outside, prevents to slide, and limiting suction cup 41's diameter will be greater than retainer plate 42, and bracing piece 43 slope sets up, and one end is close to the marginal portion with limiting suction cup 41 and fixes, can support limiting suction cup 41, avoids the too big emergence of sucking disc diameter to buckle and influences fixed effect.

In this embodiment, the fixing ring 42 is an elastic ring, and the diameter of the elastic ring in the natural state is smaller than the outer diameter of the hard tube part 20. When the elastic ring is provided around the outside of the hard tube portion 20, the elastic ring contracts inward, so that the fixing ring 42 can be stably fixed to the outside of the hard tube portion 20. When the position of the limiting device 40 needs to be moved, the elastic ring is pulled outwards.

In this embodiment, the sum of the lengths of the rigid and

flexible tubing portions

20, 30 is less than the length of the plunger 12. The puncture device inner core 12 is exposed from one end of the soft tube part 30 away from the hard tube part 20 to perform a puncture function.

In this embodiment, the length of the hose portion 30 is 4 to 8 cm. The hose portion 30 is disposed only at a portion near the puncture site, which not only reduces wear, but also ensures that the rest of the hose portion is firmly protected.

In this embodiment, the material of the flexible tube 30 is soft silicone or resin. Soft silica gel and resin are soft, are soft when contacting with organs in the abdominal cavity, cannot cause damage, are very wear-resistant, can avoid puncturing sheath damage, and prolong the service life of the choledochoscope.

To sum up, the special sheath of puncturing of cholangioscope that this embodiment provided can reduce the wearing and tearing of puncture sheath tip, prolongs cholangioscope life, and the restriction cholangioscope inserts internal degree of depth, avoids the patient to receive the injury.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
