Body formed, the stabilizer blade is set to the screw rod bottom, and is threadedly coupled by screw rod with the connecting tube.
The guide sheath convenient for fixation by adopting the above technical scheme, is provided with support device, and guide sheath is made to be easier to fix,
Ureter guide sheath is specially aside held without assistant, saves manpower, sliding is provided with silicagel pad in sheath, and silicagel pad can
It is bonded the end of patient's urethral orifice, silicagel pad matter is soft to be caused to damage to the urethral orifice of patient, while being conveniently adjusted support dress
The height set, target user are more extensive.
It further limiting, the sheath inside pipe wall is equipped with interlayer, and the top of the interlayer is equipped with LED light and miniature webcam,
Conducting wire is also equipped in the interlayer, described conducting wire one end is electrically connected with the LED light and the miniature webcam respectively, another
Draw sheath in end.
It further limits, the sheath is transparent pipe.
It further limits, the sheath pipe outer wall is coated with hydrophilic glue film.
It further limits, the hydrophilic film surface posts sterile stickup film.
It further limits, the length of the connecting tube is 5 ~ 8cm.
It further limits, the length of the screw rod is 8 ~ 12cm.
The utility model compared with the prior art for, the utility model guide sheath easy to support, and in guide sheath
Equipped with interlayer, the LED light and miniature webcam that are provided with observe the insertion situation of guide sheath convenient for doctor, avoid damage to urine output
The case where pipe and kidney, occurs, and has sterile album leave film in sheath surface adhesion, ensure that completely defending for ureter guide sheath
It is raw, it avoids probeing into patient's urethra and causes to infect, and without disinfection in advance.

Specific embodiment
In order to which those skilled in the art may be better understood, with reference to the accompanying drawings and examples to the utility model
Technical solution further illustrates.
As shown in Figure 1, Figure 2 and Figure 3 includes sheath 1 convenient for fixed guide sheath, expands pipe 2 and support device 3, described
Sheath 1 is hollow structure, and the expansion pipe 2 is penetrated from described 1 one end of sheath and is pierced by by 1 other end of sheath, the branch
Support arrangement 3 is set in the sheath 1, and is slidably connected with the sheath 1.The support device 3 includes silicagel pad 31, lantern ring
32, screw rod 33, stabilizer blade 34 and internal thread connecting tube 35 is set.The silicagel pad 31 be set in 1 outer surface of sheath and with
The sheath 1 is slidably connected, wherein the silicagel pad 31 is in a ring, and opens up at middle part fluted, is arranged in the groove
Becket 36, the lantern ring 32 are rotatablely connected with the becket 36, the connecting tube 35 be set to 32 bottom of lantern ring and with
