Description
Technical field
This utility model relates to a kind of ureteroscope, particularly relates to a kind of flexible ureteroscope, and this equipment is suitable for hospital's Urology Surgery and uses.
Background technology
Human body urinary system calculus is a kind of commonly encountered diseases, frequently-occurring disease.Remove stone operation can be divided into: External ultrasound rubble, intracavity pneumatic lithotripsy, percutaneous renal mirror art, per urethra ureterorenoscope art etc..Analyze in terms of degree of recognition, operation risk and complication rate, wound and the recovery time etc. of lithotrity effect, doctor and patient, per urethra ureterorenoscope art has certain advantage, ureterorenoscope rubble is performed the operation just in penetration and promotion, it has also become the essential therapeutic arsenals of hospital's upper urinary stone.Common operation method is, indwelling dilatation of ureter sheath after first expanding with ureterscopy mirror body, then inserts Flexible ureteroscope, seeks and calculus smashes calculus with Bladder stone.
Chinese patent 201010027201.2, open a kind of ureteroscope, including at least two sections of shanks, mirror body, each section of shank is sequentially connected with, and the tail end of back segment shank connects mirror body;Each section of shank is provided with, in mirror body, the tube chamber being interconnected;The outer wall of described leading portion shank is provided with groove, is provided with drainage channel in the tube wall of described back segment shank;Described groove is interconnected with drainage channel.The obvious using effect of this structure is poor, it is impossible to get a desired effect.
Utility model content
This utility model mainly solves the deficiencies in the prior art, it is provided that a kind of compact conformation, ensures a kind of flexible ureteroscope that operation is smoothed out.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of flexible ureteroscope, including operating portion, described operating portion is provided with operation button, one end of described operating portion is provided with insertion pipe assembly, described operating portion is provided with and inserts the instrument channel mouth that pipe assembly is connected, the other end of described operating portion is provided with assembly of finding a view, and is provided with channel components, is provided with the adjusting part matched with channel components in described operating portion in described insertion pipe assembly；
Described inserts the main flexible tube that pipe assembly includes fixing with operating portion, and the outer end of described main flexible tube is provided with bending section, and the outer end of described bending section is provided with first end；
Described assembly of finding a view includes the view finder being fixedly connected with operating portion, and described view finder is regulated mutually by focusing ring；
Described channel components includes the instrument channel being connected with instrument channel mouth, described instrument channel be arranged over thin light guide bundles, thick light guide bundles and as fine；
Described adjusting part includes regulating the most curved group of fixing handle mutually with operating portion, and the most curved group of described handle is positioned mutually by cage knob, and described operating portion outer wall is provided with light connection-peg and side leakage joint.
As preferably, the diameter of described first end is 2～4mm, and active length is 200～700mm；Channel diameter is Φ 0.5～Φ 3mm；The maximum bend angle of described bending section is 270 °；The angle of inclination of instrument channel mouth is 0 °-50 °.
Collectively constituted elongated an insertion managed by first end, bending section, main flexible tube, bladder is entered at visual lower insertion urethra, and prolong ureter and boost, after end enters renal pelvis in the ban, curved group of handle of up/down can be regulated to control the angle of bend of bending section, so that small cup on kidney, lower calyx are stretched in first end, by passing as the objective lens in termination tip portion before fibre, terminating the eyeshield (view finder) being positioned on handle afterwards.Naked eyes can observe image at eyepiece eyeshield, it is also possible to connects CCD interface, observes from monitor.Illumination light optical socket from operating portion enters, light-conductive optic fibre deliver to first end head, illumination field of view.The Bladder stone seal wire of rubble is inserted by female Luer instrument channel mouth again, and along instrument channel until stretching out first end, alignment calculus carries out rubble.Recirculated water enters from female Luer side valve, flows out along instrument channel from first end, is used for rinsing camera lens and broken calculus powder.
The angle of bend of bending section can regulate supreme curved 270 ° from plumbness 0 °, under curved 270 °, bending radius≤R12.5mm.
Cage knob can lock the most curved group of handle, thus realizes the lock function of bending section angle.
Equipment before every use after will carry out test of leaking hunting, by leak detector connect leak hunting joint detection.
The explanation of first end:
First end and main flexible tube external diameter are Φ 3mm.
Innovation and effect:
It is designed with and passively bends function, it is achieved first end enters each renal calices.Flexible ureteroscope head end bending section degree of crook is adjustable, on angle of bend curved 270 °, under curved 270 degree, bending radius≤12.5mm, and bending radius is with close first end end as minimum, it is incremented by the most successively, and be designed with at tail end and passively to bend function, when first end enters human body renal pelvis, first bent by bending section leading portion, when bending to about 180 °, passive bending section starts bending, first end may finally be realized and entering each renal calices (upper small cup, middle small cup, inferior calyx), the location to the calculus of these specific paries, and remove calculus with Bladder stone etc..
A kind of flexible ureteroscope that this utility model provides, contributes to reducing operating time, reduces operation risk, beneficially operation and smoothly completes.
