Abstract
The invention provides the conduit of a kind of ureterscopy operation, be made up of seal wire, water inlet, water inlet side opening, catheter body, outlet, seal wire embeds pipe inner wall, and the head end of seal wire has one section of soft head and stretches out catheter body, is being provided with 2 symmetrical water inlet side openings near inlet end.Conduit of the present invention combines together with seal wire, and head end is that soft wire first injects in ureter, and soft head contributes to preventing damage ureter and renal pelvis, both washes by water in sustainable drainage, and can prevent ureter perforation and need to change open surgery again.Conduit of the present invention can reduce ureter in art, Renal pelvic pressure effectively, keeps surgical field of view clear, is conducive to reducing postoperative complication, saves operating time, ensure surgical quality.The phenomenon that the ureterscopy rubble intraoperative hemorrhage that the invention solves existence at present causes the visual field unclear, avoids priming petock and causes ureter and renal pelvis inner high voltage, reduce or eliminate the problems such as concurrent pyemia.
Description
Technical field
The invention belongs to the technical field of medical apparatus and instruments, relate to the conduit of a kind of ureterscopy operation, this conduit replaces the safety guide wire effect of ureterscopy operation.
Background technology
On clinical medicine, the operation of ureterscopy rubble need guide ureteroscope to pass in and out in ureter by safety guide wire, prevents ureter perforation equivalent damage.Enhancing perfusion normal saline is needed to keep ureteroscope to get a clear view in ureterscopy lithotrity; The a large amount of flushing water of operative process enters urinary tract, raises Renal pelvic pressure, causes antibacterial, toxin enters in the short time and enter blood circulation in a large number, produce a large amount of inflammatory factor, cause systemic inflammatory response.How making to reduce ureter, Renal pelvic pressure in ureterscopy lithotrity, effectively prevent traditional ureteroscope lithotrity to cause pyemia, is the difficult problem that current urology is paid close attention to.
Summary of the invention
The object of this invention is to provide the conduit of a kind of ureterscopy operation, be made up of seal wire, water inlet, water inlet side opening, catheter body, outlet, seal wire embeds pipe inner wall, and the head end of seal wire has one section of soft head and stretches out catheter body, is being provided with 2 symmetrical water inlet side openings near inlet end.
The present invention is in ureterscopy lithotrity, water injection through pipe mouth end enters calculus position from ureteroscope handle hole, the soft seal wire of seal wire head end crosses calculus, water injection through pipe mouth is positioned at below ureteral calculus, in art, flushing water keeps dilatation of ureter by ureter handle hole Continuous Perfusion and gets a clear view, can continue during priming petock to be drained to ureter external drainage from water injection through pipe mouth by outlet, both the effect of ureter renal pelvis low pressure had been maintained, especially, when surgical field of view mucosal bleeding, keep again getting a clear view.The seal wire (comprising soft head) that inlet end stretches out catheter body enters to above calculus from crossing calculus between ureter wall and calculus, prevents injury of ureter from can not find passage, plays safety guide wire and guides ureterscopy to enter ureter effect.Thus ensure that ureterscopy rubble completes smoothly, be conducive to saving operating time, reduce postoperative complication and occur, be conducive to saving operating time, ensure the features such as surgical quality.
Conduit of the present invention is that one can replace safety guide wire effect in ureterscopy lithotrity, conduit combines together with seal wire, head end is that soft wire first injects in ureter, soft head contributes to preventing damage ureter and renal pelvis, both can wash by water in constant drainage art, and can ureter perforation be prevented and need to change open surgery again.Conduit of the present invention can reduce ureter in art, Renal pelvic pressure effectively, keeps surgical field of view clear, is conducive to reducing postoperative complication, saves operating time, ensure surgical quality.The phenomenon that the ureterscopy rubble intraoperative hemorrhage that the invention solves prior art existence causes the visual field unclear, avoids priming petock and causes ureter and renal pelvis inner high voltage, reduce or eliminate the problems such as concurrent pyemia.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cross-sectional structure schematic diagram of conduit of the present invention.
Detailed description of the invention
Below by drawings and Examples, the technical scheme of invention is described in further detail.
embodiment 1
See Fig. 1, Fig. 2, a kind of conduit of ureterscopy operation, be made up of seal wire 2, water inlet 3, water inlet side opening 4, catheter body 5, outlet 6, seal wire 2 embeds pipe inner wall, together with conduit combines with seal wire 2, both can wash by water in constant drainage art, and can ureter perforation be prevented and need to change open surgery again.The head end of seal wire 2 has one section soft 1 and stretches out catheter body 5, is being provided with 2 symmetrical water inlet side openings 4 near water inlet 3 end.Seal wire 2 head end is in soft first reeve ureter, and a bit of soft head is front, and stiff guide wire is rear, and soft head contributes to preventing damage ureter and renal pelvis tissue.
embodiment 2
During ureterscopy rubble operation technique, water injection through pipe mouth 3 end of the present invention injects from ureterscopy handle hole, cross calculus for soft 1 of seal wire head end, make water injection through pipe mouth 3 be positioned at below calculus, catheter proximal end soft 1 crosses calculus, is positioned at ureteral lumen above calculus, when pouring into physiological saline solution in art in ureteroscope handle hole, catheter body 5 intracavity constant drainage priming petock flows out from conduit outlet 6, maintains surgical field of view clear, and maintains low pressure in ureter.Soft 1, seal wire front end is crossed calculus and is positioned at ureteral lumen, plays safety guide wire effect, prevents ureter wall from damaging and can not find passage and cause ureteroscope to get lost, and plays safety guide wire and guides ureterscopy to enter ureter effect.Thus ensure that ureterscopy rubble completes smoothly, be conducive to saving operating time, reduce postoperative complication and occur, be conducive to saving operating time, ensure the features such as surgical quality.
