Description
【Technical field】
The present invention relates to a kind of electronics Flexible ureteroscope and its operating method with real-time pressure monitoring function, belongs to medical treatment
Instrument field, it is especially interior to peep instrument field.
【Background technology】
Electronics and fiber Flexible ureteroscope treatment ureteral calculi, especially electronics Flexible ureteroscope treatment kidney stone technology
Emerging technology as the minimally invasive endoscope treatment urolithiasis of current Urology Surgery and following mainstream development direction, and it is right at present
The minimum minimally invasive recognition and acceptance for taking stone to perform the operation, increasingly obtaining doctor and patient of patient's operation wound, in American-European flourishing state
Family, the wide utilization of Chinese comparatively developed regions.
, it is necessary to first insert soft lens guide sheath in operation, then electronics Flexible ureteroscope is sent into guide sheath and carries out soft lens operation.
To keep getting a clear view in art, it is necessary to using modes such as syringe, pressurization bag of saline or charge pump pressurizations, through electronics ureter
Soft lens instrument channel injects perfusion liquid to operative region.After inserting soft lens, the gap between electronics Flexible ureteroscope and guide sheath
As the flow-guiding channel of perfusion liquid.It is also soft because soft lens guide sheath is longer (being commonly used for 35cm/45cm), drive in the wrong direction and put sheath
Multiple bending sections are easily formed afterwards, and electronics Flexible ureteroscope passes through guide sheath bending section, and is easily formed at multistage blocking, causes to draw
Stream is not smooth, and moment or in short-term Renal pelvic pressure increase that amplitude is larger, easily exceedes and is even pressed safely considerably beyond 30mmHg renal plevis
Power higher limit.Clinical research proves that Renal pelvic pressure is more than 30mmHg, and operating time is longer, postoperative pyrexia, and septicopyemia occurs
The occurrence probability of the severe complications such as mass formed by blood stasis, nephrorrhagia can increased.
So the Renal pelvic pressure of monitoring electronics Flexible ureteroscope working region is very important in real time, and it is clinical at present
Electronics Flexible ureteroscope used, do not possess the monitoring function of operative region Renal pelvic pressure in real-time, accurate art.
Renal pelvic pressure is monitored in present electronics/fiber Flexible ureteroscope surgery, there are following several ways at present：
1) drive in the wrong direction insertion ureteral catheter, connects central venous pressure monitoring system or Urinary functional test monitor, obtains defeated
Perfusion hydraulic coupling in urinary catheter conduit；
2) central venous pressure monitoring system or urine are connected at the instrument channel water inlet valve port of electronics/fiber Flexible ureteroscope
Hydromechanics monitor, obtain electronics/fiber Flexible ureteroscope instrument channel and the intraoral injection pressure of water intaking valve；
3) in the external measuring pressure passage port part of soft lens guide sheath, (hereinafter referred to as external port part and enters mirror at the passage
Passage merges) sensor is set, and central venous pressure monitoring system or Urinary functional test monitor are connected, obtain soft lens guide sheath
External port part perfusion hydraulic coupling and electronics/fiber Flexible ureteroscope and soft lens guiding intervaginal spaces perfusion/drainage pressure；
4) the soft lens guide sheath with independent side path is inserted, side path is with entering mirror passage full section and being not communicated with, laterally
Channel distal end mouth (internal port) is concordant with soft lens guide sheath far distance port (internal port).Pass through the end of the independent side path
Mouthful, if connection central venous pressure monitoring system or Urinary functional test monitor, obtain the perfusion hydraulic coupling in side path；
5) percutaneous renal puncture passage is established, imports conduit and fixation, connects central venous pressure monitoring system or uroflow power
Hygienic monitoring on hands of childhood instrument, obtain the perfusion hydraulic coupling in conduit；
However, this above-mentioned several pressure measurement mode monitor the pressure data of acquisition, it is not real-time, accurate workspace
Domain Renal pelvic pressure, or the Renal pelvic pressure of real-time, accurate electronics/fiber Flexible ureteroscope working region can not be obtained.Cause
For in electronics/fiber Flexible ureteroscope operation, the pressure of terminal prot is injected in the port of soft lens leading end portion, i.e. perfusion liquid, just
The perfusion hydraulic pressure of working region, be only the operation of electronics/fiber Flexible ureteroscope in real time, it is most accurate, most have clinical value
Renal pelvic pressure data.

Protection domain in.
In addition, the present invention also discloses the operation method to kidney stone under a kind of Flexible ureteroscope based on this electronics, specifically
Flow is as follows：
(1) take a ureterscopy, guiding wire inserted in ureterscopy retrograde, along seal wire mirror to UPJ, and
The tube wall of the ureteroscope of urethral orifice carries out mark；
(2) indwelling seal wire, the ureterscopy exited in the first step；
(3) suitable soft lens guide sheath (containing obturator) is selected according to patient gender, age, physique, with regard to adult patient
Speech, generally women selection work length 35cm, male's selection work length 45cm soft lens guide sheath (containing obturator)；
(4) front port of the soft lens guide sheath containing obturator is concordant with the port of ureteroscope, guide sheath sheath wall is marked
The scale of knowledge corresponds to the mark of the tube wall of ureteroscope, and this corresponding scale is the length terminal that soft lens guide sheath enters human body；
(5) seal wire is penetrated in the obturator front end tip channel of soft lens guide sheath, ureteroscope is inserted urethra, until
Bladder, then soft lens guide sheath is under the guiding of seal wire, into bladder, and under the monitoring of ureterscopy, into ureter
Opening, be then log out ureterscopy；
(6) under the guiding of seal wire, soft lens guide sheath is delivered in the 4th step at the corresponding scale identified, exits closed pore
Device, optionally now, the length of soft lens guide pins can be monitored by C arms X-ray machine and determines calculus position；
(7) by the electronics Flexible ureteroscope with real-time pressure monitoring function, i.e. the present embodiment connects charge pump, according to clinic
Operation needs, and the working region pressure security upper limit (not above 30mmHg) is set on charge pump, and complete electronics in vitro
The test of bending property up and down, the Real-Time Perfusion pressure monitoring functional test of Flexible ureteroscope, after having tested, by the present embodiment along soft
Mirror guide sheath enters in kidney；
(8) seal wire is exited, by adjusting the adjusted device in the present embodiment on operating portion 4, i.e. crank handle 41, reaches tune
Bent-segment portion 2 turns to and bent, until finding calculus；
(9) by taking the treatment of lower calyx calculus as an example, first with calculus catching net-like means calculus is entangled as far as possible and upper small cup in moving to is (through the
Triple channel 103 enters any apparatus, such as calculus catching net-like means, laser fiber, seal wire, it is necessary to resets bending section 2 and stretches, similarly hereinafter), this
Operation can reduce the bending of the electronics Flexible ureteroscope bending section 2 with real-time pressure monitoring function of this case, mitigate laser fiber
Loss；Can also evade as far as possible causes the angle of bend of bending section 2 to reduce because third channel 103 inserts laser fiber, influences soft
