Description

A kind of plugging device for ureteroscope lithotrity

Technical field

The utility model is related to medical instruments field, and in particular to a kind of plugging device for ureteroscope lithotrity.

Background technology

Ureteroscope lithotrity is that ureteroscope per urethram enters in ureter through bladder, by Bladder stone technology by urine output Calculus in pipe spies on lower accurate crushing stone in ureteroscope guiding, recycles set stone basket or lithotomy forceps that calculus is taken out.So And, taking the repeated multiple times turnover ureter forceps gripping stone of stone with set stone net or lithotomy forceps can increase mucous membrane of ureter damage, cause art The possibility of ureterostenosis, making patients' state of an illness, heavier injury is brought to patient's physiology and psychology afterwards.

Further, since ureteral calculi blocks, obstruction above ureter and the expansion of kidney ponding are often resulted in, using ureter Bath must be driven in the wrong direction when mirror carries out taking stone, in art to ensure that surgical field of view is clear.But calculus is usually escaped with retrograde current To kidney, so as to influence calculus rubble success rate, and unnecessary damage is easily caused to patient.

Utility model content

The purpose of this utility model is directed to the deficiency of prior art presence, there is provided a kind of simple structure, takes the cubic meter of stone just, and Effectively prevent in calculus ease and mucous membrane of ureter caused to damage, it is to avoid repeatedly take that stone causes that conditions of patients aggravates for urine output The plugging device of pipe mirror lithotrity.

The technical solution of the utility model

To reach above-mentioned purpose, adopt the following technical scheme that：A kind of plugging device for ureteroscope lithotrity, including one The conduit of individual front end closing, is provided with closure air bag near the front end of the conduit, telescope chamber, seal wire are provided with the conduit Tube chamber, flushing tube chamber and the air bag tube chamber connected with the closure air bag, have one between the telescope chamber and the closure air bag The hatch frame of set a distance, the flushing tube chamber is laid with some apopores at the hatch frame, and the guidewire lumen is passed through Wear the front end that the closure air bag extends to conduit.

The telescope chamber is cambered surface transition structure in hatch frame end.

The front end of the conduit is tapered structure, and its end head is spherical structure.

The telescope chamber is circular or polygonal tube cavity configuration.

Some indicating strips are laid with the conduit outer wall.

Positive beneficial effect of the present utility model

Compared with prior art, the utility model simple structure, take the cubic meter of stone just, by catheter proximal end set closure gas Capsule, so as to effectively realize blocking up the nearly kidney end seal of ureter, it is to avoid during rubble, escapes in calculus, causes the state of an illness to add patient The unnecessary trouble such as again, in addition, by setting telescope chamber, it is easy to the insertion of ureteroscope, and in telescope chamber and closure gas The hatch frame of certain distance is set between capsule, calculus can be crushed in this position effectively, the calculus after crushing, by rinsing Tube chamber feedwater is rinsed, and calculus is excreted from telescope chamber, quickly, convenient, it is to avoid rubble is deposited in bladder, reduces patient's art Heel row stone is born, beneficial to patient's post-operative recovery, it is to avoid easily cause the generation of degree of impairment to patient ureter using set stone network capacity, Simultaneously, it is to avoid stone is taken using the repeated multiple times turnover of lithotomy forceps, it is to avoid mucous membrane of ureter is caused to damage, prevents from causing postoperative urine output Manage narrow making patients' state of an illness, bring heavier injury to patient's physiology and psychology.

It is the utility model simple structure, easy to operate, take the cubic meter of stone just, it is practical, beneficial to patient's post-operative recovery, it is worth wide General popularization and application.

Brief description of the drawings

The utility model is further described below in conjunction with the accompanying drawings：

Fig. 1 is the section structure schematic diagram of the utility model conduit；

Fig. 2 is the A-A profile structure diagram of Fig. 1；

Fig. 3 is the B-B cross-section structure diagram of Fig. 1；

Fig. 4 is the structural representation of the utility model embodiment two.

Specific embodiment

With reference to specific embodiment, the utility model is expanded on further.

Embodiment one

Referring to Fig. 1-3：A kind of plugging device for ureteroscope lithotrity, including a conduit 1 for front end closing, it is described The front end of conduit 1 is tapered structure, and its end head is spherical structure, is easy to being satisfactorily implanted for plugging device, near the front end of conduit 1 Closure air bag 2 is provided with, closure air bag 2 is suitable with the diameter thickness of conduit 1 in implantation process, during closure, by inside it Water-filling, expands it, by the closure of ureter upper end.

The gas for telescope chamber 7, guidewire lumen 4 being provided with the conduit 1, tube chamber 5 being rinsed and is connected with the closure air bag 2 Capsule tube chamber 3, the telescope chamber 7 is circular tube chamber structure, has certain distance between the telescope chamber 7 and the closure air bag 2 Hatch frame, makes calculus exposed to herein, is easy to ureteroscope to be inserted so far from telescope chamber 7, carries out rubble operation.The telescope Chamber 7 is cambered surface transition structure 8 in hatch frame end.The flushing tube chamber 5 is laid with some apopores at the hatch frame 6, by water supply in tube chamber 5 is rinsed, being flowed out from apopore 6, realize the flushing to rubble.The guidewire lumen 4 is through described Closure air bag 2 extends to the front end of conduit 1, realizes coordinating with seal wire, and plugging device is put into patient ureter.

Embodiment two

Referring to Fig. 3, Fig. 4：The present embodiment is with the difference of embodiment one：The polygon tube chamber knot of the telescope chamber 7 Structure, is easy to ureteroscope to keep space with telescope chamber 7, in the case where ureteroscope is not exited, you can realize effectively row's stone.Institute State and some indicating strips 9 are laid with the outer wall of conduit 1, indicating strip 9 is easy to patient to control the entrance depth location of plugging device, makes calculus Effectively at the hatch frame in plugging device, make operation technique more convenient, accurately.

The utility model avoids being escaped on rubble by blocking air bag, and is rinsed by rinsing tube chamber feedwater, makes calculus from mirror Tube chamber is excreted, quickly, convenient.It is the utility model simple structure, practical, beneficial to patient's post-operative recovery, it is worth extensive Popularization and application.

The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This practicality is new The technology contents of the not detailed description of type are known technology.
