Description
Technical field
A kind of ureter bracket of this utility model relates to for ureteral bracing frame, can effectively discharge the urine of accumulation in renal pelvis smoothly and form effective support to ureter by assisting patients.
Background technology
1) ureter bracket is existing for many years in Urology Surgery clinical practice.Its one end is in renal pelvis, and one end, at intravesical, is that one can drain into intravesical urine from kidney, and ureter can be avoided to form the common medical apparatus of cicatrix.
2) first Zimskind in 1967 etc. have reported and have done long-term drainage through cystoscope Retrograde expansion silica gel tube, successfully alleviate ureteral obstruction and the leakage of ureter vagina. thus make the long-term implanted treatment of ureter bracket conduit obtain universal and development.1978, Finhey used two J type silica gel support pipe clinically, and the problem solving stent tube aversion and come off, to today, can say that ureter bracket has become the requisite part of modern Urology Surgery, is modal upper urinary tract drainage way.
3) in the clinical practice of ureter bracket, along with to ureter bracket operation convenience, biocompatibility, the understanding in depth and studying of a lot of problem such as infections relating, biofilm formation, support tube burn into crust, it designs the development that experienced by again and again.Some new biomaterial for medical purpose, new processing technology continue to bring out, update the physicochemical property of ureter bracket, improve biocompatibility, eliminate support tube implant related complication become the new problem of researcher.
There is a lot of Related product in the market, but no matter at present which kind of product, not damaged and convenient recovery all cannot be taken out these two kinds of functions external or require perfect adaptation by its intravesical tail end design.
They have obvious shortcoming:
1) except adopting wire coil and being exposed to external design, other all tail end design all needs the cystoscope when reclaiming support, adopts apparatus to regain, causes the increase of medical treatment cost, the inconvenience of recovery, the discomfort of patient.
2) adopt wire coil and be exposed to external design, it need people in vitro tractive coil support is pulled out, at this moment just there is the potential mucosa injury and patient's discomfort that are caused by urethra after tail end gives a discount, even if do not give a discount, damage and patient's discomfort also can be caused because of non-harmless sawtooth design.
So be necessary that designing a kind of new support meets the actual market demand.
Summary of the invention
This utility model object is, for above-mentioned weak point, to provide a kind of ureter bracket; When support collected by needs, by directly pulling the pull rope being connected to support tail end, the ureter bracket pull-out directly will be built in human bladder, decreases operation cost, shortens treatment time, decrease the misery of patient, have larger use value.
A kind of ureter bracket is made up of support, pull rope; Described support one end is bending J-shaped or arc, and top is provided with opening; The other end is closed avette conehead, and avette conehead is narrowing gradually near end diameter, and the limit of avette conehead has two urine outlets, and a urine outlet is near avette conehead, and another urine outlet is away from avette conehead; Support offers multiple through hole;
Pull rope is connected with on the top of avette conehead.
Described pull rope adopts tinsel, nylon yarn, plastic wire or litzendraht wire.
Described number of openings is no less than one.
Operation principle: this utility model realizes its research and development object function by following content:
A) be placed in body by wire guide and push rod by support: single J-shaped or arc tail end are positioned in renal pelvis, avette conehead tail end is placed in intravesical, and the line or the coil pull-out that are connected to taper end are external.
B) single J-shaped of renal pelvis side or arc tail end can put movement into preventing support in body time (in ureter) at support.
C) pipeline of support by middle hollow and the drain of opening realization to urine of two ends and stake body surrounding.
D) the avette conehead tail end of bladder side is when recovery operation is by urethra, has become to the external head end withdrawn from.Now because the design of the avette conehead of taper, without just rushing to summit situation to the tearing of mucosa, can realize the minimum impact on mucous membrane of urethra and damage, it is faster and smooth-going that the process of withdrawal becomes.
Be connected to line or the coil of avette conehead tail end, relative to traditional J-shaped or arcuate structure, decrease the stimulation to bladder, and if long enough exposed words in vitro, can realize without the need to second operation (under cystoscope, apparatus takes out ureter bracket), taking-up support fast and safely.
This utility model tool has the following advantages:
1) the avette conehead tail end design of bladder side, on the minimum impact of mucous membrane of urethra and damage when can be implemented in recovery operation, it is faster and smooth-going that the process of withdrawal becomes.
2) rear-end line or coil is connected, relative to traditional J-shaped or arc or pig tail type structure, decrease the stimulation to bladder, and if long enough exposed words in vitro, can realize without the need to second operation (under cystoscope, apparatus takes out ureter bracket), taking-up support fast and safely.
By above-mentioned two advantages together, conveniently reclaim function when realization is auxiliary without the need to cystoscope, and the object of damage is reduced as far as possible to mucosa.Finally play and reduce medical care precess and medical treatment cost, alleviate the effect of patient's discomfort.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 is a kind of ureter bracket structural representation of this utility model.
Fig. 2 is the using state schematic diagram of a kind of ureter bracket of this utility model.
Detailed description of the invention
With reference to accompanying drawing 1-2, a kind of ureter bracket is made up of support 1, pull rope 2; Described support 1 one end is bending J-shaped or arc, and top is provided with opening; The other end is that closed avette conehead 1-1, avette conehead 1-1 are narrowing gradually near end diameter, and the limit of avette conehead 1-1 has two urine outlet 1-2, and a urine outlet 1-2 is near avette conehead, and another urine outlet 1-2 is away from avette conehead 1-1; Support 1 offers multiple through hole 1-3;
Pull rope 2 is connected with on the top of avette conehead 1-1.
Described pull rope 2 adopts tinsel, nylon yarn, plastic wire or litzendraht wire.
