Description
Technical field
The present invention relates to a kind of urological surgery medical instrument, especially a kind of ureterscopy that can attract.
Background technique
Ureteroscope is the endoscope for Urology Surgery Minimally Invasive Surgery, is mainly used for the treatment of calculi in urinary system, hand
Ureteroscope is protruded into bladder cavity by urethra when art, then enters ureteral lumen from Ureteral orifice, by ureteroscope defeated
Urinary catheter is intracavitary to be detected, and is removed using related rubble instrument by intra-ureteral calculus is broken.
Introducing ultrasonic rubble is a much progress.The ultrasonic probe of early stage be it is hollow, while renal plevis and ureter rubble
Also rubble is sucked out.Probe diameter originally is 8Fr, not can enter the work cavity of ureteroscope.In this way, ureteroscope is first used
See that calculus positions, then take out mirror, change to ultrasonic probe rubble, this operation easy damaged ureter manufactures again later
Thinner probe (1.5-2 mm dia) out, hard straight because popping one's head in, part is invisible when zero degree mirror operates, and has thus produced again
Angle mirror, direct-view rubble is handy under mirror, and later ureteroscope is designed to zero degree mirror and angle mirror, the two can mutual phase inversion,
With zero degree mirror when entering mirror, angle mirror when ultrasonic rubble is used.Further improvement has been done again by Circon ACMI company, manufacture
Half soft or hard mirror out.This mirror has used fiber illuminated, is formed flexible " gooseneck shape eyepiece ", visible angle is very big.The mirror influences
So far is not only suitable for ultrasonic rubble, is equally also suitble to the use of other rubble instruments.
In order to mitigate the pain of patient and into the needs of mirror, it is desirable that the mirror body diameter of ureteroscope is as small as possible；And in order to
Doctor needs convenient for operation and perfusion, and requires the operating walk way lumen diameter of shank as big as possible.In surgical procedure, doctor will
It operates instrument and from the instrument of mirror body tail portion protrudes into mouth and protrude into lumen and perform the operation, and stream is persistently injected to operative site by lumen
Dynamic water is to keep clear visual field.With the progress of operation, the water of operative site can gradually become cloudy because of rubble powder, influence to regard
Wild clarity, at this moment must just stop filling the water, and by muddy water by lumen discharge, or operative site in addition
A conduit is inserted into dedicated for the discharge of sewage, refills Xin Shui again after sewage is drained.
Therefore in use, water filling and draining can only all be carried out existing ureteroscope by same cavity, be infused
Water and draining cannot carry out simultaneously, this just makes traditional ureteroscope, and there is following disadvantages:
1, since water filling and draining can only operate separately, water can not be formed and recycled, not lead in surgical procedure the visual field often not
It is clear；
2, sustained water injection keeps mirror front end and Renal pelvic pressure excessively high, if operating time is longer, results even in aggregation system
It is hydraulic excessively high, at this moment must just exit in ureteroscope discharge aggregation system after liquid, be inserted into ureteroscope and re-operate；
3, water filling is operated separately with draining, also be will affect the calculifragous efficiency of operation, is obviously prolonged operating time.
The mirror sheath edge of early stage ureteroscope is as cystoscope, and the design of beak sample is got into trouble often entering mirror, it is usually
It will lead to the tearing of ureteral mucous epithelium.Current design is formed into oblique angle, makes it easier into mirror, and mirror sheath section is standing to be calculated as
Triangle or oval are to cater to biggish work cavity.Ureterscopy has one or two work cavities, and two cavities make
A road is obtained as operation instrument, another road does perfusion and be used.The single channel of one larger caliber is allowed using biggish
Instrument presss from both sides out stone debris or tissue biopsy, and the selection of the two is depending on the purpose for the treatment of.It is defeated after the 1990s
Urinary catheter mirror obtains continuous perfect, and the introducing of fiber waveguide beam greatly reduces the bore of ureteroscope.Interior aperture of mirror it is very thin
Change and the diversification of type (rigid, half rigid, soft mirror), Ureteroscopy greatly change the office for the treatment of lithangiuria
Face, and it is established in the status of intracavitary Urology Surgery.At present, ureteroscope is handled in ureter, lower ureteral stones have can not
The superiority of substitution, with hard and the soft ureteroscope same period develop in addition, including ultrasound, liquid electricity, Pneumatic Lithotripsy and laser
Head, these equipment make the modern ureteroscope rubble of miniaturization more effective.Existing many rock crushing plants are applied to clinic, these
Device can be by the service aisle of ureteroscope, and can arbitrarily manipulate and steering activity.
It may be implemented to fill the water the ureteroscope carried out simultaneously with draining in surgical procedure for this purpose, people further study, such as
101879056 B of Chinese patent CN discloses a kind of ureteroscope, by adding drainage channel, realizes in operation and passes through shank
Lumen sustained water injection, the groove of shank outer wall persistently drains, and can accelerate the drainage speed in operation, form continuous water and follow
Ring can increase the displacement in surgical procedure under the premise of not influencing surgical procedure, can not only keep in surgical procedure
The visual field it is clear, improve the efficiency of operation, and renal plevis and intra-ureteral pressure can be reduced, prevent postoperative bacteremia, urine
The generation of source property pyaemia septica.But this device cannot intelligence control art in pressure, for this purpose, Chinese patent CN 103767744
B discloses medical perfusion platform, and the pressure measuring unit feedback in transit chamber is automatically controlled to platform attracts negative pressure, makes cavity pressure
This guarantees operation safety in safe range, takes stone to improve procedure efficiency further through automatic suction, but this platform needs plus uses urine output
Pipe soft lens sheath needs to use Flexible ureteroscope sheath logical as the guidance conveying of disengaging human body urinary system cavity in actual operation
Road, clinically still smooth implementation of some patients because can not be successfully merging Flexible ureteroscope sheath influence operation.
