Description
Technical field
The present invention relates to endoscopic technique field, in particular to a kind of endoscope working sheath knot for urological surgery
Structure.
Background technology
Endoscope is to have concentrated materialogy, traditional optical, ergonomics, precision optical machinery, hyundai electronicses, mathematics, software
Deng in the advanced medical apparatus of one, medically using quite varied.Flexible ureteroscope operation in, ureter it is soft in peep
Mirror can be entered observation diseased region in vivo with per urethra and operating theater instruments can be coordinated to carry out visualization operative treatment in vivo.Face
Internal inspection and visualization operative treatment on bed need the endoscope of image clearly to help doctor to improve the accuracy of diagnosis,
But the existing endoscope performed the operation for Flexible ureteroscope is flexible-pipe endoscope, though human body will not be damaged in operation, due to
Flexible pipe, which is hampered after power, to advance difficult, causes flexible pipe to be difficult to be accurate to up to operative site, it is impossible to the accurate diseased region of reflection completely
Lesion situation, causes surgical procedure not smooth, while increase operating difficulty, also increases operating time and the pain of patient,
Also improve surgery cost.
The content of the invention
It can be accurate to up to operative site there is provided one kind present invention aim to the deficiency for solving above-mentioned background technology,

Attractor interface or water injection interface.
Still more preferably, can be in the soft sheath and hard sheath of soft or hard sheath or hard sheath to effectively reduce intrarenal pressure power
Open several circular decompression holes arranged by different modes in head end periphery.
The beneficial effects of the invention are as follows：Plug coordinates existing endoscope in Urology Surgery as a kind of transition guider
Used in operation, soft lens can be made to be accurate to up to diseased region, be to carry out operation by soft lens in the later stage to provide the foundation, mainly as
Visual ureterectasia sheath is applied in renal plevis, calyceal calculus and other related surgicals, is passed through while having in surgical procedure
Negative-pressure ward, which arranges decompression in stone and kidney, by plug and the fit structure of working sheath, makes plug and hard sheath or soft or hard sheath group
Conjunction enters in human body under visibility status along seal wire, reaches and plug extraction is put into soft lens to diseased region again after predetermined position
Observed, coordinate operating theater instruments to be performed the operation, and by vacuum suction machine interface rubble can suctioned out external or reached
The effect of intrarenal pressure power is reduced, method is simple, it is easy to operate.The chief component of endoscope working sheath includes：1st, from ribbon gymnastics
Make handle, (1-2 interface) with vacuum suction interface, hard sheath or flexible soft or hard sheath；2nd, carry endoscope path way,
The plug of silk guide passage and waterflood path；3 collect the string bag of the rubble pumped out in art.In urological surgery, first
Plug and working sheath are combined into one, then (in advance will can also be consolidated endoscope in the image channel of endoscope insertion plug
Change in plug), insertion method is similar with the method for existing product, is combined into the soft or hard sheath of visual ureter or hard sheath, so
Plug and working sheath combination carry out upper sheath along seal wire afterwards, can be with the situation of Real Time Observation ureter, Ke Yishi during upper sheath
When water filling to wash ureter open, the location of working sheath can accurately be judged by Real Time Observation.On working sheath in place after
Extract plug out, upper soft lens carries out conventional Flexible ureteroscope operation, soft lens observation is coordinated in surgical procedure.By soft or hard sheath along soft lens
Renal plevis, kidney calices are pushed into, vacuum suction machine is connected to the vacuum suction interface of working sheath, using the operation handle of working sheath, matched somebody with somebody
Close soft lens and enter each kidney calices, it was observed that starting vacuum suction during rubble, rubble is suctioned out external.Or using the behaviour for moving back mirror
Make mode to take calculus in vivo out of.The endoscope working sheath of the present invention is simple in construction, coordinates convenient with plug, practical,
In upper sheath operating process can by the situation of the endoscope Real Time Observation ureter in plug, can also water filling in real time to wash open
The position of ureterostenosis, accurate detection working sheath puts sheath position, is that the providing for mirror that enter of soft lens facilitates, soft lens can be accurate to
Up to diseased region, coordinate operating theater instruments to carry out operation on ureter, reduce patient suffering, while reducing operating difficulty, improve
Success rate of operation, reduces operating time, with good market application value and medical value, is applicable but is not limited to painstaking effort
Pipe intervention, gynaecology, Jia Ru sections, neurosurgery and orthopaedics and other do not refer to relevant clinical medical field.

Calculus is taken out of in vitro with the mode for moving back mirror.
The application method of endoscope working sheath designed by the present invention is：In Ureteroscopy, plug 3 is peeped with interior
Mirror working sheath 2 is combined into one, plug clamping joint 4 and endoscope handle 1 are combined into one (or not by plug clamping joint 4 with
Endoscope handle 1 is combined, and carries out water flood operations by a human hand held plug clamping joint 4, and another human hand held endoscope handle 1 makes interior
Sight glass working sheath 2 enters in human body and controls the trend of endoscope working sheath, and two people's separate operations reduce operating difficulty, increases
Procedure efficiency), it (will can also be solidificated in endoscope path way), combine in advance in the image channel 7 of endoscope insertion plug 3
Into visual ureter working sheath structure, then seal wire is inserted in the silk guide passage 5 of plug 3, plug 3 and endoscope working sheath
2 combination imports operative site by seal wire, can be real-time during sheath in the combination of plug 3 and endoscope working sheath 2
The situation of ureter is observed, can be adjusted during the power that is hampered by the real-time water filling of waterflood path 6 to wash ureter open by Real Time Observation
The position of whole seal wire and endoscope working sheath 2 makes endoscope working sheath 2 be accurate to up to surgery location, is arrived in endoscope working sheath 2
Plug 3 is extracted out after up to operation position, soft lens is inserted in endoscope working sheath 2, carries out conventional Flexible ureteroscope operation.Performing the operation
By operating steering operation mechanism 12 to adjust the position of soft lens in journey, soft or hard sheath is set to enter renal plevis, kidney calices and can position, soft lens is matched somebody with somebody
Close operating theater instruments to smash the calculus in renal plevis, kidney calices, vacuum suction machine joint 30 is connected into Negative pressure machine, when soft lens observation
Start Negative pressure machine during to rubble, while making soft lens front end exit soft sheath 2.2, rubble is suctioned out by body by the negative pressure in soft sheath 2.2
Outside, manually it is positioned in the string bag 24, operation carries out unified cleaning to the rubble in the string bag 24 after terminating.It is interior designed by the present invention
The structure of sight glass combination plug 3 and plug clamping joint 4 can be such that soft lens is accurate to up to operative site, coordinate operating theater instruments to carry out urine output
Pipe is performed the operation, easy to operate, and surgery location is accurate, reduces the amount of bleeding of patient, is reduced the operation pain of patient, is improved simultaneously
Procedure efficiency and success rate.
The above described is only a preferred embodiment of the present invention, not doing any formal to the structure of the present invention
Limitation.Any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example,
In the range of still falling within technical scheme.
