Description
Technical field
The present invention relates to a kind of medical apparatus, specifically a kind of D-J pipe extractor.
Background technology
At present, known in clinically many urologic disease client need manage at renal pelvis ureters intravesical indwelling D-J, D-J pipe is placed internal needs after playing therapeutical effect and is taken out, can not Preserving time in health, need when taking pipe apply cystoscope equipment, be operated, medical procedure is loaded down with trivial details, medical expense is high, and patient has misery, and has damage bladder, urethra and cause or increase the weight of to infect equivalent risk.
D-J pipe be in a kind of medical domain short-term indwelling in the intra-ureteral medical apparatus and instruments of human body, it it is the flexible catheter having certain degree of hardness, generally manufactured by silica gel, all footpaths 4.8-7 millimeter, one end is positioned at kidney, the other end is positioned at intravesical, and end such as pigtail-shaped is tortuous, to reduce the risk causing D-J pipe to shift because of the wriggling of ureter muscle.Mechanism of action is to support ureter and drain kidney urine entrance bladder.Application target is that urine enters bladder etc. in the prevention of stricture of ureter and treatment and drain kidney.
Summary of the invention
For solving the deficiencies in the prior art, the present invention provides a kind of D-J pipe extractor, including outer catheter and have resilient interior lasso trick, it is characterized in that described outer catheter is cylindricality flexible pipe and outer catheter top is hemispherical end face, if outer catheter is outer catheter bottom relative to the other end on outer catheter top, outer catheter top is provided with a through hole to outer catheter bottom, described interior lasso trick is built in described through hole, if interior lasso trick one end is open end for connection end, the other end, described connection end is connected with outer catheter top, and described open end extends to outside outer catheter bottom.
Further, one end of described through hole is positioned at side, outer catheter top.
Further, described outer catheter top is provided with an arcuate groove, described interior lasso trick connect end be positioned at described arcuate groove one end and when lasso trick is in tension lasso trick extend to outside outer catheter through arcuate groove and described through hole successively.
Further, described outer catheter bottom is provided with push-and-pull set.
Further, described outer catheter bottom is provided with mark one, described mark one and the opening homonymy of through hole catheter tip outside.
Further, extend to the interior lasso trick surface outside outer catheter described in and be provided with mark two.
Further, described interior lasso trick described mark two when tension is 8 ~ 13cm away from outer catheter bottom, can be used to limit and push the lasso trick diameter that intravesical interior lasso trick is formed, due to child with to become human bladder in different size, the distance away from outer catheter bottom 8 ~ 13cm can be scheduled on by identifying two.
Further, described outer catheter week footpath can be 8 to 16mm, manufacture size, a length of 28cm can be determined according to children and adults, material is latex or silica gel, interior lasso trick week footpath 1mm, and cross section is circular, and material is medical silica-gel or medical latex.
The distinguishing feature of the present invention is to take injury of bladder and urethra risk, infection risk in the operation of D-J pipe to reduce, and alleviate that patient is painful, save medical resources and a kind of medical device product of providing.
Accompanying drawing explanation
Fig. 1 is the perspective view of the present invention；
Fig. 2 is the side-looking structural representation of the present invention；
Fig. 3 is the Section A-A figure of Fig. 2.
1 it is wherein outer catheter, 2 is interior lasso trick, 3 is that mark two, 4 is push-and-pull set, 5 is through hole, 6 is outer catheter top, 7 is arcuate groove, 8 is mark one.
Detailed description of the invention
nullAccording to Fig. 1、Shown in Fig. 2 and Fig. 3，The present invention is specially a kind of D-J pipe extractor，Including outer catheter 1 and have resilient interior lasso trick 2，It is characterized in that described outer catheter is cylindricality flexible pipe and outer catheter top 6 is hemispherical end face，If outer catheter is outer catheter bottom relative to the other end on outer catheter top，Outer catheter top to outer catheter bottom is provided with a through hole 5，Described interior lasso trick is built in described through hole，The one end open of through hole is positioned at side, outer catheter top，Other end opening is positioned at outer catheter bottom，Described outer catheter top is provided with an arcuate groove，Arcuate groove one end connects the one end open of through hole，The other end is positioned at the opposite side of this opening，If interior lasso trick one end is for connecting end、The other end is open end，Described connection end is connected with outer catheter top and this connection end is positioned at the arcuate groove side relative to via openings，Described open end extends to outside outer catheter bottom.When interior lasso trick is in tension, interior lasso trick extends to outside outer catheter through arcuate groove and described through hole 5 successively.Described outer catheter bottom is provided with push-and-pull set 4, conveniently inserts or pull out in urethra by outer catheter, and described outer catheter bottom is provided with mark 1, described mark one and the opening homonymy of through hole catheter tip outside.The described interior lasso trick surface extended to outside outer catheter is provided with mark 23, and interior lasso trick described mark two when tension is 13cm away from outer catheter bottom.Outer catheter week, footpath can be 8 to 16mm, can determine manufacture size, a length of 28cm according to children and adults, and material is latex or silica gel, interior lasso trick week footpath 1mm, and cross section is circular, and material is medical silica-gel or medical latex.
During use by the mark one of outer catheter upward, by patient's urethra, bladder is inserted on outer catheter top, it is inserted into urine to stop from internal outflow of outer catheter, illustrate the top of outer catheter to be reached opening of bladder, now outside for interior lasso trick catheter interior is pushed until stopping when mark two arrives outer catheter bottom, interior lasso trick front end is about 4cm at intravesical one annular lasso trick of formation and lasso trick diameter, again by trocar sheath 90-degree rotation, direction of rotation can check it is to place D-J pipe in left side or right side to determine according to patient medical record, lasso trick in tension again, interior lasso trick can lock the end of D-J pipe, interior lasso trick and outer catheter together being extracted can be by D-J pipe from taking out in the patient.
