Abstract
The present invention is soft uretero-renoscope with hard sheath has the advantages of both hard uretero-renoscope and soft uretero-renoscope combined. After the soft uretero-renoscope with hard sheath is pushed through the ureteric orifice to the renal pelvis similar to operating one hard uretero-renoscope, the relevant members in the hard sheath are controlled to extend the soft uretero-renoscope from the hard sheath to the different parts of the renal calices, so as to reach the diagnosis and treatment aim. With combined advantages of both hard uretero-renoscope and soft uretero-renoscope, the soft uretero-renoscope with hard sheath has convenient operation and easy expanding.
Description
One, technical field
Be used for intracavity Urology Surgery treatment ureteral calculus, renal pelvis calyceal calculi, diagnosis tumor of renal pelvis, tumor of ureter, renal pelvis ureters hemostatic treatment etc.
Two, background technology
The hard mirror of ureter is easy to operate, but front end can't be crooked, therefore can't treat renal pelvis, calyceal calculi and carry out the diagnosis of renal pelvis renal calices tumor through ureter by the hard mirror of ureter.Ureter soft lens front end is flexible, scalable direction behind the arrival renal pelvis, enter and to carry out various diagnosis and treatment after respectively organizing renal calices, but be pushed into very difficulty of renal pelvis from ureteric orifice, often need X line location compounding practice, and laser damages the camera lens of soft uretero-renoscope easily in the work, is difficult in the clinical position apply.The soft uretero-renoscope of the hard sheath of band that we invent has the advantage of hard mirror of ureter and soft lens concurrently, and has overcome shortcoming separately, and easy damaged ureteroscope camera lens does not have great practicality.
Three, summary of the invention
This invention comprises: hard sheath part, dismantled and assembled soft lens part.
Hard sheath part: be toughness and the moderate hardware of rigidity, can be decomposed into components A, part B, parts C three parts.
Components A: long 61cm, external diameter 0.39cm, internal diameter 0.38cm, front end are lymphogranuloma inguinale shape, and the lower part of front end is the inclined-plane, conveniently enters the ureteric orifice (see figure 1); Apart from front end 49cm place the circular outer suspension member of one long 1.05cm is arranged, wherein 0.75cm is a fixture, and the rear end remainder is screw thread and packing ring; The long 4.8cm (see figure 2) in rear end.
Part B: long 11cm, front end external diameter 1cm is female thread, and internal diameter is 0.75cm, and rear end external diameter 0.9cm is external screw thread, internal diameter 0.8cm, rear end external screw thread head of district 0.8cm (see figure 3).
Components A maintains static (see figure 4) with after part B is connected in the work.
Parts C: long 12.4cm, the external diameter 0.7cm of front end 2cm, internal diameter 0.55cm.
The long 8cm of mid portion, diameter 0.5cm indicates the scale of 1cm, wherein the outer ring hangs with on major axis slidably 3 parts, from front to back the plug-in X of called after, plug-in Y, plug-in Z (the long 0.5cm of plug-in X, the plug-in Y diameter of diameter 0.75cm 0.8cm respectively, thick about 0.15cm is plastic washer; The long 1cm of plug-in Z, diameter 1.2cm)
The long 1.5cm in rear end, external diameter 1cm, internal diameter 0.5cm, the forward part of the rear end of parts C has flushing liquor perfusing hole (being labeled as I), the high 0.6cm of I, diameter 0.6cm, there is the external screw thread (see figure 5) of 0.2cm on the top.
Parts C is used as the hard mirror time spent with after part B is connected, and only has the forward part of parts C to be embedded in the part B, and plug-in Z and the complete interlock of part B by parts C middle part, can't seesaw.When need used soft lens, then can slide in part B in the middle part of parts C, so that soft lens stretches out hard sheath front end (see figure 6).
Dismantled and assembled soft lens part: can be decomposed into soft lens body A, cross structure B, extending channel C three parts.
The long 73cm of soft lens body A, the transversal Fig. 7 that meets personally, the front end sealing of the video channel of front end, optical-fibre channel, direction control channel part can be avoided damage from laser in the work.The service aisle front opening can pass through for flushing liquor and laser fiber (or biopsy forceps).
Cross structure B is a plastic member, and long 4.4cm is X, Y, Z part from front to back.The partly long 0.9cm of X has external screw thread; The partly long 0.3cm of Y, diameter 0.55cm; It is trapezoidal that Z partly is, the wide 0.6cm of forward part, and the wide 1.5cm in rear section, trapezoidal height are the 3.1cm (see figure 8).
Extending channel C comprises w, x, four passages of y, z, places the inside of soft lens body A by cross structure.The w passage is a video channel, and the x passage is an optical-fibre channel, and the y passage is a service aisle, and the z passage is the direction control channel of soft lens front end, can make the crooked (see figure 9) of soft lens front end by the steel wire in the joystick pulling control channel.
Soft lens is partly placed hard sheath partial interior, and the rear end that makes hard sheath portion C is with after the X partial fixing of the cross structure B of soft lens is connected, promote hard sheath parts C forward, the soft lens front end is stretched out from hard sheath front end in various degree, thereby reach enter ureter and on shift the similar hard mirror operation of renal pelvis onto, and after hard sheath front end arrives renal pelvis, then soft lens can be released in sheath, realize the purpose of soft lens work.
Four, description of drawings
Five, the specific embodiment
Allow the parts C and the part B of hard sheath part be in hard mirror mode of operation, and be completely fixed, parts C and part B can't be slided, correct concordant this moment with hard mirror sheath front end before the dismantled and assembled soft lens, in the case, can enter renal pelvis fully by hard ureteroscope operation; Afterwards, parts C by controlling hard sheath part makes dismantled and assembled soft lens stretch out hard sheath front end partly to some extent with the slip of part B, z passage by the control soft lens makes the bending in various degree of soft lens front end, the parts C that rotates hard sheath part can make dismantled and assembled soft lens front end reach with part B or enter different renal calicess or renal pelvis position, the purpose that reaches diagnosis and treat.
