Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of band utricule ureter seal wire and application method.
Background technique
Ureteral calculi is one of most common disease of urological department.With the fast development of endoscopic technic in the recent decade,
Under ureteroscope lithotrity be treat in ureter, one of the most commonly used method of lower ureteral stones, compared to traditional ureteralithotomy
Shi Eryan is taken, lithotrity has operation repeatability under ureteroscope, operation is non-invasive, post-operative recovery is fast, patient suffering is few etc.
Advantage has passed through and has started large-scale popularization use in County Hospital.
The key point of lithotrity success or not under ureteroscope is restricted at present other than the operation of doctor is horizontal, it is mainly defeated
Can urinary catheter mirror smoothly reach ureteral calculi position.In practice, because ureter is more narrow, ureteroscope lithotrity is being carried out
When be commonly encountered ureteral distortion section, stone location can not be gone upward to so as to cause ureteroscope.In the prior art, for ureter
Narrow problem, Partial Hospitals using settling mode under the scopes such as ureter expander, foley's tube, cool spare system, and for
Ureteral distortion is generally oriented to by guide frames such as superslide seal wires.
Lithotrity is entered back into due to entering bladder from urethra into ureter under ureteroscope at present, in the process of rubble
In, for rubble when broken, part rubble can be up in kidney due to impact, water flow, air-flow etc. causes calculus to be removed
It is unclean while bringing pain to patient.
Summary of the invention
Rubble can be prevented to be up in kidney or to part the technical problems to be solved by the present invention are: providing one kind
Band utricule ureter seal wire and the application method that ureterostenosis is expanded.
In order to solve the above-mentioned technical problem, a kind of technical solution that the present invention uses are as follows:
A kind of band utricule ureter seal wire, including guidewire body, conveying assembly and the soft head of spring, the conveying assembly and bullet are provided
The soft head of spring is connected on the both ends of guidewire body；
There is the inflatable elastic sack body shunk on the guidewire body of the soft head of the close spring, also have in the guidewire body
It is connected to the channel of elastic sack body and conveying assembly.
In order to solve the above-mentioned technical problem, a kind of technical solution that the present invention uses are as follows:
A kind of application method with utricule ureter seal wire, including above-mentioned band utricule ureter seal wire, comprising:
Step 1: driving the elastic sack body of guidewire body to be brought into the ureter between calculus and kidney by the soft head of spring
Portion；
Step 2: making elastic sack body expansion closing ureter with channel by conveying assembly and being crushed to calculus；
Step 3: after clearing up the calculus of crushing, by conveying assembly elastic sack body is shunk and will be with utricule urine output
Pipe seal wire takes out.
The beneficial effects of the present invention are: by using elastic sack body and inside the ureter between calculus and kidney
Shi Jinhang expansion, can temporary closure ureter, by the closed time carry out rubble, the rubble avoided is with water flow or impact
Equal a variety of causes enter in kidney, at the same within the closed time also can disposably at bladder and elastic sack body expansion it
Between more rubbles continuously crushed, highly shortened the time of operation, to reduce the sense of discomfort of patient；Also can
By elastic sack body to being expanded at the ureterostenosis of part, as spasm is narrow narrow with oedema formation；It is soft by spring
Head bypasses calculus convenient for band utricule ureter seal wire, avoids the bending of conventional guide wires using soft good bending effect of spring
Effect difference causes seal wire that calculus is back into kidney.

Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: by using elastic sack body and in the ureter between calculus and kidney
Expanded when portion, can temporary closure ureter, by the closed time carry out rubble, the rubble avoided is with water flow or punching
Equal a variety of causes are hit to enter in kidney.
It is soft to please refer to Fig. 1 and Fig. 5, a kind of band utricule ureter seal wire, including guidewire body 1, conveying assembly and spring
First 2, the conveying assembly and the soft head 2 of spring are connected on the both ends of guidewire body 1；
There is the inflatable elastic sack body 3 shunk on the guidewire body 1 of the close soft head 2 of spring, gone back in the guidewire body 1
Channel 13 with connection elastic sack body 3 and conveying assembly.
Further, the guidewire body 1 includes wire guides 11 and the overlay film 12 that 11 surface of wire guides is arranged in.
Further, the wire guides 11 are the wire with certain flexibility.
Further, the channel 13 is arranged in wire guides 11, between wire guides 11 and overlay film 12 or on overlay film 12.
Further, 3 ring of elastic sack body is located on 11 surface of wire guides.
Seen from the above description, the elastic sack body 3 in wire guides 11 is located at by ring, can be avoided the straight of guidewire body 1
The increase of diameter, so that seal wire preferably passes in and out ureter.
Further, the overlay film 12 is superslide film.
Seen from the above description, the preferably disengaging ureter of guidewire body 1 is enabled to by superslide film.
Further, the outer surface of the guidewire body 1 is provided with graduation mark 4.
Seen from the above description, by the setting of graduation mark 4, medical staff understand that band utricule ureter seal wire protrudes into
Length and speed can be estimated, avoid excessive velocities or cause sense of discomfort to patient slowly excessively.
Further, the surface of the soft head 2 of the spring and elastic sack body 3 is provided with superslide coating.
Seen from the above description, by superslide coating, the inside of human body that the disengaging of the soft head 2 of spring can be facilitated tortuous.
Further, the conveying assembly is detachably connected with guidewire body 1, and the conveying assembly is syringe or fills
Air valve.
A kind of application method with utricule ureter seal wire, including above-mentioned band utricule ureter seal wire, comprising:
Step 1: driving the elastic sack body 3 of guidewire body 1 to be brought into the ureter between calculus and kidney by the soft head 2 of spring
It is internal；
Step 2: making the expansion of elastic sack body 3 closing ureter with channel 13 by conveying assembly and being crushed to calculus；
Step 3: after clearing up the calculus of crushing, by conveying assembly elastic sack body 3 is shunk and will be with utricule urine output
Pipe seal wire takes out.
As can be seen from the above description, the beneficial effects of the present invention are: by using elastic sack body 3 and it is in calculus and kidney
Between ureter inside when expanded, can temporary closure ureter, by the closed time carry out rubble, what is avoided is broken
Stone enters in kidney with a variety of causes such as water flow or impacts, at the same within the closed time also can disposably to bladder with
More rubbles between elastic sack body 3 expands continuously are crushed, and highly shortened the time of operation, to reduce disease
The sense of discomfort of people；It also can be by being expanded at 3 pairs of part ureterostenosis of elastic sack body, as spasm is narrow and oedema is formed
It is narrow；By the soft head 2 of spring, using the good bending effect of the soft head 2 of spring, convenient for band utricule ureter seal wire around knot
Stone avoids the bending effect difference of conventional guide wires from causing seal wire that calculus is back into kidney.
