When, need to use a kind of pressure sheath, the pressure sheath is by playing the sheath of channeling and playing the expander of expanding pilot
Composition.When being inserted into pressure sheath, sheath is inserted into ureter under the guidance of expander together.Doctor can only in clinical use
Judge whether the depth of ureter guide insertion internal organs is suitable according to clinical experience, since patient's physiological anatomic architecture has visitor
Usually there is the problems such as pressure sheath insertion depth is insufficient or insertion depth is too deep in the individual difference of sight.Finally, it not only leads
It causes entire operation bigger difficulty occur, and pain can be brought to patient.Furthermore in operation on urinary system, in renal plevis
Pressure must carry out real-time monitoring, too high or too low all to cause greatly to injure to patient.
Summary of the invention
In view of the technical problems existing in the prior art, the utility model provides a kind of direct-viewization ureter guide sheath,
The insertion situation of guide sheath can either be observed in the case where visual, and the pressure that sheath is subject to can be monitored in real time.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows: direct-viewization ureter guide sheath, packet
Include sheath, expansion pipe, lever and display screen.The sheath and the expansion pipe are hollow structure, and the expansion pipe is from described
Sheath one end penetrates and is pierced by by the sheath other end, and the lever is set in the sheath pipe end, and the display screen is fixed
Below the lever.It is evenly spaced on the outer surface of the sheath to be equipped with groove, pressure sensing is provided in the groove
Device is provided with more first conducting wires in the sheath tube wall, and first conducting wire one end is connect with pressure sensor, the other end with
Display screen connection.The inner wall of the expansion pipe is equipped with hollow interlayer, is equipped in the hollow interlayer positioned at the end of extension end micro-
Type camera and LED light, the second conducting wire is also equipped in the hollow interlayer, and the miniature webcam and the LED light are logical
Cross the second conducting wire and external power electric connection.
Direct-view ureter guide sheath by adopting the above technical scheme, it is uniformly distributed fluted on sheath tube outer surface, and recessed
It is provided with pressure sensor in slot, LED light can be additionally provided in the end of expansion pipe in order to monitor the pressure size that sheath is subject to
And miniature webcam, operate medical staff in the case where visual to the importing of expansion pipe.
It further limits, the inner wall of the hollow interlayer is coated with transparent heat insulating dope.
It further limits, the surface of the sheath is coated with hydrophilic glue film.
It further limits, sterile stickup film is posted on the surface of the hydrophilic glue film.
It further limits, the end of the expansion pipe is dome-type.
The utility model compared with the prior art for, the LED light and miniature webcam of setting make operator visual
In the case where the case where being operated, avoiding damage to ureter and kidney generation, and have sterile album leave in sheath surface adhesion
Film ensure that the clean hygiene of ureter guide sheath, avoids probeing into patient's urethra and causes to infect, without disinfection in advance.Exist simultaneously
The inner wall of hollow interlayer is provided with transparent heat insulating dope, prevents LED light from so that patient is not felt good due to fever, the expansion of dome-type
Opening tube end, expansion pipe will not be caused to damage to the urethra of patient.
Detailed description of the invention

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.
Direct-view ureter guide sheath as shown in Figure 1, Figure 2 and Figure 3 includes sheath 1, expansion pipe 2, lever 3 and display screen
4.The sheath 1 and the expansion pipe 2 are hollow structure, and the expansion pipe 2 penetrates and from described 1 one end of sheath by the sheath
1 other end of pipe is pierced by, and the lever 3 is set in 1 end of sheath, and the display screen 4 is fixedly arranged on 3 lower section of lever.Institute
State it is evenly spaced on the outer surface of sheath 1 be equipped with groove 11, be provided with pressure sensor 12, the sheath in the groove 11
