Abstract
A calculus closure device is a medical instrument which is used for grabbing and removing calculi and other foreign matters in the urinary system in an endoscope mode. The calculus closure device comprises an outer sheathing catheter, an inner core and a propeller, wherein the inner core is arranged in the outer sheathing catheter, the impeller is arranged at the near end of the outer sheathing catheter, and a stretching memory alloy spring is arranged at the section at the far end of the inner core. The calculus closure device is simple in structure, convenient to use and capable of reducing calculus drifting in surgeries and improving the calculus removing rate. Pain related to calculus removing of postoperative patients can be reduced, and calculus fragments can be removed out of the ureter orifice one by one after lithotripsy is completed.
Description
Technical field
The present invention relates to medical apparatus and instruments, relate in particular to a kind of for capture, remove the calculus of urinary system and the medical device of other foreign body in endoscope's mode.
Background technology
In recent years, under ureteroscope, the operation of rubble gets more and more, and in ureteroscope lithotrity, along with the increase of rubble energy, calculus drift rate also increases gradually.The calculus of drift usually needs further Surgery Treatment because fragment is excessive, as ureter soft lens lithotrity, ureter soft lens trap stone art or ESWI, not only increase patient suffering, extends operating time, more increases risk and medical treatment cost that postoperative infection generates heat.The more important thing is that residual calculus fragment will become the new one-tenth lithophysa heart, more painful secondary upper urinary tract infection and renal colic, bring to patient.Therefore, reduce calculus drift in art, increasing calculus clearance rate is the major issue of ureteroscope lithotrity.
Utility model content
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and a kind of calculus stopper is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
Calculus stopper, comprises epitheca pipe, inner core and propeller, and inner core is arranged in epitheca pipe, propeller be arranged on epitheca pipe near-end, one section of described inner core far-end is set to retractility memory alloy spring.
In this utility model, the external diameter of described inner core is 0.51 ~ 0.6mm, more smaller than epitheca bore, can in epitheca pipe, slide by free-extension.
Operation principle of the present utility model is: by stretching inner core enter in epitheca pipe linearly, insert endoscopic working channel, under direct-view through more than calculus gap 1cm, push propeller, the retractility memory alloy spring of inner core far-end is released to epitheca pipe, naturally revert to spring-like, form shutoff barrier and enter sealed condition.
Compared with prior art, the invention has the advantages that: this utility model is simple in structure, easy to use, can reduce calculus drift in art, and improve calculus clearance rate, and reduce postoperative patient calculus dependency pain, after rubble completes, calculus fragment is removed outside ureter tract one by one.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model preferred embodiment.
In figure: propeller 1, epitheca pipe 2, inner core 3, retractility memory alloy spring 4.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand; below in conjunction with Figure of description, the invention will be further described with concrete preferred embodiment, but protection domain not thereby limiting the invention.
Calculus stopper, comprises epitheca pipe 2, inner core 3 and propeller 1, and inner core 3 is arranged in epitheca pipe 2, propeller 1 be arranged on epitheca pipe 2 near-end, one section of described inner core 3 far-ends is set to retractility memory alloy spring 4.
While using calculus stopper described in the utility model to carry out the operation of ureter calculus, the lower hydrophilic seal wire tailing edge of the superslide seal wire of settling of direct-view enters mirror, visit and calculus, calculus stopper distal site is immersed in normal saline to approximately 5～10s, make the moistening of calculus stopper hydrophilic coating, then inner core 3 is inserted to endoscopic working channel at retractility memory alloy spring 4 under deployed condition, until the front end of calculus stopper stretches out endoscope; Push the propeller 1 of calculus stopper, gently handle is pushed away forward after surmounting calculus completely, until handle to kayser after locking position puts in place, thereby to guarantee that retractility memory alloy spring 4 recovers contraction state and forms sealed condition completely.After fixing calculus, use air pressure trajectory to smash calculus to diameter completely with 0.3 ~ 0.4kpa or holmium laser and be less than 2mm, and under endoscopic observation, slowly outside tractive stopper propeller 1, hauls out Ureteral orifice until bladder by calculus fragment; Finally, by slow handle post-tensioning, until kayser puts in place, with endoscopic observation, after guaranteeing that calculus stopper turn inner core launches completely, mistake endoscope path way exits external, or exits together external with endoscope.
Claims (2)
1. calculus stopper, comprises epitheca pipe, inner core and propeller, and inner core is arranged in epitheca pipe, propeller be arranged on epitheca pipe near-end, it is characterized in that, one section of described inner core far-end is set to retractility memory alloy spring.
2. calculus stopper according to claim 1, is characterized in that, the external diameter of described inner core is 0.51 ~ 0.6mm, more smaller than epitheca bore.
