The specific embodiment
As shown in the figure: a kind of self-enclosed Retroperitoneal balloon dilator, comprise breather 1 and expanded balloon 2, one end opening of breather 1 connects expanded balloon 2, the other end opening of breather 1 connects the air inlet source, described dilator also includes self-enclosed device, and self-enclosed device is arranged on breather 1 interior position near expanded balloon 2;
Described self-enclosed device is comprised of Unidirectional air inlet valve 3, fixed axis 4, pull bar 5 and backguy 6, Unidirectional air inlet valve 3 is arranged in the breather 1, fixed axis 4 is arranged between Unidirectional air inlet valve 3 and the expanded balloon 2, and the two ends of fixed axis 4 fixedly are embedded in the inwall of breather 1; Described fixed axis 4 passes pull bar 5 and arranges, pull bar 5 can be rotated around fixed axis 4, one end connecting stay wire 6 of pull bar 5 corresponding dilating sacculus 2, the other end of pull bar 5 arranges stopper 7, stopper 7 is close to Unidirectional air inlet valve 3 all the time towards the sidewall of expanded balloon 2 one sides, one end of described backguy 6 is connected with pull bar 5, the other end of backguy 6 is connected to the inwall of expanded balloon 2, original state, Unidirectional air inlet valve 3 is opened and is inflated, and along with the inflation increase of expanded balloon 2, drives backguy 6 pulling pull bars 5 and rotates, in the rotation process, the valve plate that stopper 7 promotes Unidirectional air inlet valve 3 finally makes Unidirectional air inlet valve 3 closures.
Described backguy 6 is provided with three at least, comprises a backguy 6, this backguy 6 be connected apart from pull bar 5 expanded balloon 2 inwall places farthest.Described fixed axis 4 and breather 1 axial vertical setting.Described stopper 7 is spherical stopper 7.
Original state, Unidirectional air inlet valve 3 is in opening, and breather 1 connects the air inlet source, and gas is entered in the expanded balloon 2 by breather 1, in the process of inflation, since the continuous expansion of expanded balloon 2, the backguy 6 that pulling is connected with expanded balloon 2 inwalls, and then pulling pull bar 5 rotates, in rotation process, the valve plate that stopper 7 one ends of pull bar 5 withstand Unidirectional air inlet valve 3 overturns, and finally reaches detent position, finishes self-enclosed.Can also be by manual push-and-pull breather 1 in the use procedure, balloon dilator is directly sealed, when in gas replenishment process, the degree of heaving of the expanded balloon that makes discovery from observation 2 has satisfied the needs of expansion, this moment, dilator did not also carry out self-closed, can breather 1 be pulled outward with hands, because expanded balloon 2 is stuck in the patient body, in the breather 1 outer process of drawing, backguy 6 drives pull bar 5 and rotates, in rotation process, the valve plate that stopper 7 one ends of pull bar 5 withstand Unidirectional air inlet valve 3 overturns, and reaches detent position.Self-enclosed Retroperitoneal balloon dilator of the present utility model, simple to operate, in operation process, only need a people just can finish whole expanding, and has self-enclosed function, when airbag aeration when the required degree, can seal voluntarily, greatly facilitate in clinicist's the art and operate, alleviate doctor's operating pressure, improve the effect of operation.
