Background technique
Clinically, human body need to be treated in ureteral obstruction or generation calculus by surgical procedure, and during operation
Need to establish operation path, by operation path import instrument or other operation, performed the operation with facilitating, through frequently with means
Cooperating Flexible ureteroscope for ureter guide sheath, the merging of ureter guide sheath per urethra mouth sets pipe through bladder, urine output canal path,
To establish the service aisle of Flexible ureteroscope.The rubble surgical procedure of urinary system is clinically carried out with Flexible ureteroscope
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 present invention provides a kind of direct-viewization ureter guide sheaths, can
Enough insertion situations that guide sheath is 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 by the invention is as follows: direct-viewization ureter guide sheath, including sheath
Pipe, expansion pipe, lever and display screen.The sheath and the expansion pipe are hollow structure, and the expansion pipe is from the 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 fixedly arranged on institute
It states below lever.It is evenly spaced on the outer surface of the sheath to be equipped with groove, it is provided with pressure sensor in the groove, institute
It states and is provided with more first conducting wires in sheath tube wall, first conducting wire one end is connect with pressure sensor, the other end and display
Screen connection.The inner wall of the expansion pipe is equipped with hollow interlayer, takes the photograph positioned at the end of extension end equipped with miniature in the hollow interlayer
As head and LED light, it is also equipped with the second conducting wire in the hollow interlayer, the miniature webcam and the LED light pass through the
Two conducting wires 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 present invention compared with the prior art for, the LED light and miniature webcam of setting make operator in visual feelings
The case where being operated under condition, avoiding damage to ureter and kidney generation, and have sterile album leave film in sheath surface adhesion, it protects
The clean hygiene for having demonstrate,proved ureter guide sheath avoids probeing into patient's urethra and causes to infect, without disinfection in advance.Simultaneously in hollow folder
The inner wall of layer is provided with transparent heat insulating dope, prevents LED light from so that patient is not felt good due to fever, the expansion pipe end of dome-type
Expansion pipe will not be caused to damage to the urethra of patient in portion.
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 technology of the present invention
Scheme 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
