Description
Technical field
This utility model relates to medical instruments field, it is a kind of per urethra bladder rubble stone taking device, especially when merging the isthmus prostatae hypertrophy, can carry out rubble to the intravesical calculus and get stone, also convenient to for example transplanted kidney ureter pathological changes processing of driving in the wrong direction of ectopic ureteral orifice simultaneously.
Background technology
When prostatic hyperplasia merges vesical calculus, generally adopt per urethra chamber mirror technology to reach and do not have the purpose of earning stone.Yet, for the patient of isthmus prostatae hypertrophy and since calculus generally all hypostasis be hidden in outstanding isthmus prostatae rear in the bladder lowest order because the angle problem, the middle period of projection has been hindered and has adopted the hard mirror device of tradition to operate.Though adopt the soft lens technology can rubble, if adopt traditional straight sheath, be unfavorable for that fixedly calculus is carried out rubble, also be unfavorable for taking out calculus, very inconvenient.In addition, the transplanted kidney ureter calculus or situation such as narrow occur and often needs the operation of driving in the wrong direction of per urethra transplanted kidney ureter, same because transplanted kidney tubal bladder anastomotic stoma angle problem and very inconvenient.Such difficulty also is present in behind the tubal bladder replantation again, and morbidity becomes when needing per urethra to drive in the wrong direction operation.
The utility model content
This utility model is intended to solve the isthmus prostatae hypertrophy and merges the problem that per urethra endoscope-assistant surgery rubble under the vesical calculus situation is got the stone difficulty, and ureter pathological changes under the retrograde treatment of the per urethra ectopic ureteral orifice situation, the special-purpose rubble stone taking device that provides a kind of suitable cooperation soft lens to use.This device is convenient to be fixed isthmus prostatae hypertrophy patient intravesical calculus, takes out for the calculus that smashes is convenient simultaneously.When handling transplanted kidney ureter pathological changes or tubal bladder replantation infectious-related complication, this rubble stone taking device can help the patient more easily to expand out the tubal bladder anastomotic stoma, carries out next step operation.
In order to achieve the above object, the technical scheme that provides of this utility model is:
A kind of per urethra bladder rubble stone taking device comprises the tubulose epitheca of hollow, can insert in the epitheca and the obturator that coincide with it; Described epitheca comprises straight sheath and bends sheath with the front end of straight sheath smooth connection; Described obturator comprises shaft-like body and ball head; Described shaft-like body front end is provided with cone-shaped component, and described ball head end is provided with tapered rod, and described cone-shaped component and tapered rod are hinged.
Wherein, the curved sheath of described front end is 30～45 ° with the angle of straight sheath, is preferably 40 °; Described epitheca end is provided with obturator screens breach, and described shaft-like body afterbody is provided with the screens button that engages with obturator screens breach; Described epitheca end is provided with bonnet, is provided with the waterproof partition between described bonnet and the epitheca end, and described bonnet and waterproof partition center are equipped with through hole, are convenient to soft lens and pass through; Between described bonnet and the epitheca by being threaded; Described epitheca afterbody is provided with operating grip; Described shaft-like body end is provided with caudal peduncle, is convenient to send into and extract out obturator; When described obturator was in the state that inserts epitheca, described shaft-like body was fitted with straight sheath inwall, the port of the curved sheath of described ball head sealing.
The utility model is described in further detail below in conjunction with design principle:
This utility model is got stone sheath head end with this rubble and is modified into elbow sheath pipe, and is used front end and can becomes angular deformation to free in and out the obturator of curved sheath head.This obturator is divided into head end and rod end, and head end is spherical and to conical transition, and the rod end part that is connected with head end is connected through the hinge.Obturator head end hinge becomes to insert curved sheath head after the angular deformation and is combined into the urethral probe shape, insert behind the bladder clockwise or be rotated counterclockwise 180 degree, pull out obturator, take over control water partition and screw thread bonnet behind the curved sheath, insert soft lens in the aperture from the screw thread bonnet and enter curved sheath, soft lens water filling filling bladder, observe the calculus configuration, adjust the curved sheath position of rubble, and fix calculus with the curved sheath of rubble, adopt laser lithotripsy.After calculus smashes, open curved sheath bonnet, intravesical hydrops can be gone out calculus easement sheath.Repeat rubble and get the stone process, all calculus of intravesical all can be taken out.
Handling ectopic ureteral orifice for example during the terminal calculus of transplanted kidney ureter, to bend sheath earlier and insert bladder, insert under the existing soft lens direct-view and find transplanted kidney ureter opening, push down ureter around openings wall of urinary bladder with curved sheath head, the ureter opening is wrapped in wherein, by soft lens bath, the local hydraulic pressure that raises struts ureteric orifice, inserts ureteral catheter again or seal wire is further operated.
Concrete using method is as follows:
Referring to Fig. 4 and Fig. 5, insert obturator 2 in the epitheca 1, because the guide effect of the curved sheath 11 of front end, ball head 21 slides to curved sheath 11 ports of front end, 3 one-tenth angular deformations of hinge of cone-shaped component 23 and tapered rod 22 hinged places.The obturator screens breach of screens button 25 collimation sheaths 12 rear ends of obturator 2 rear ends, and snap in fully wherein, at this moment, ball head 21 just in time blocks curved sheath 11 ports of front end.With the method for the aforementioned device that assembles by known placement urethral probe, after per urethra is inserted bladder, the Rotate 180 degree, the isthmus prostatae that makes the curved sheath 11 of front end walk around the hypertrophy hypertrophy points to the trigone of urinary bladder, extracts obturator assembly 2 then.Bonnet 16 is tightened with the screw thread of straight sheath tail end by the mode of rotation, and waterproof partition 15 is secured between the two.By the aperture in the middle of the bonnet 16, existing soft lens 4 is sent in the epitheca 1.Soft lens 4 water receiving filling bladders, find the intravesical calculus after, push down calculus with the curved sheath 11 of front end, insert laser lithotripsy optical fiber in the soft lens 4 and carry out rubble, wash blood clot or broken calculus in the visual field if desired, then turn on bonnet 16, intravesical hydrops easement sheath flows out, and plays the effect of going out calculus simultaneously.
The calculus that smashes accumulates in the curved sheath 11 of front end, and soft lens 4 direct-views down can be with the curved sheath 11 of front end near wall of urinary bladder, and it is revolved 180 degree, does the action that similar spoon is ladled out vegetable soup, and calculus slides to the curved sheath 11 of front end and sheath 12 connecting portions directly along tube wall, washes by water it is gone out.
When handling ectopic ureteral orifice, after the curved sheath 11 of front end inserted bladder, insert existing soft lens 4, find ectopic ureteral orifice under the direct-view, push down ureter around openings wall of urinary bladder with curved sheath 11 heads of front end, the ureter opening is wrapped in wherein, by soft lens 4 baths, the local hydraulic pressure that raises struts ureteric orifice, inserts ureteral catheter again or seal wire is further operated.
The beneficial effect of this patent utility model is, can be combined isthmus prostatae hypertrophy patient intravesical calculus easily and carry out rubble and get stone, and is also convenient to the treatment of driving in the wrong direction of ectopic ureteral orifice pathological changes, and simple in structure simultaneously, convenient manufacturing and popularization.
