Abstract
The invention relates to a self-closing air bag expander for a back abdominal cavity. The self-closing air bag expander comprises a vent pipe and an expansion air bag and further comprises a self-closing device composed of a one-way air inlet valve, a fixed shaft, a pull rod and a pull thread. The one-way air inlet valve is arranged in the vent pipe, the fixed shaft is arranged between the one-way air inlet valve and the expansion air bag, the pull rod penetrates the fixed shaft to be arranged and can rotate around the fixed shaft, one end of the pull rod corresponding to the expansion air bag is connected with the pull thread, a blocking head is arranged at the other end of the pull rod, the pull thread is an elastic pull thread, and the other end of the pull thread is connected onto the inner wall of the expansion air bag. The self-closing air bag expander for the back abdominal cavity is simple to operate. Only one operator is required in the operation process to finish the whole expansion work. The air bag expander has a function of self closing, can be closed by itself when the air bag is aerated to the required extent, greatly facilitates in-operation operation of clinical doctors, reduces operation pressure of the doctors and improves operation effect.

Reference numeral: 1, breather, 2, expanded balloon, 3, the breather cheek valve door, 4, fixed axis, 5, pull bar, 6, backguy, 7, the retaining head.
The specific embodiment
As shown in the figure: a kind of self-enclosed pneumoretroperitoneum 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 the position of close expanded balloon 2 in the breather 1;
Described self-enclosed device is made up of breather cheek valve door 3, fixed axis 4, pull bar 5 and backguy 6, breather cheek valve door 3 is arranged in the breather 1, fixed axis 4 is arranged between breather cheek valve door 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 of pull bar 5 corresponding dilating sacculus 2 connects backguy 6, the other end of pull bar 5 arranges retaining 7, retaining 7 is close to breather cheek valve door 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, breather cheek valve door 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, retaining 7 valve plate that promote breather cheek valve door 3 finally make breather cheek valve door 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 retaining 7 is spherical retaining 7.
Original state, breather cheek valve door 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 the retaining of pull bar 57 one end withstand breather cheek valve door 3 overturns, and finally reaches detent position, finishes self-enclosed.Can also be by manual push-and-pull breather 1 in the use, 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 also sealed automatically, can breather 1 be pulled outward with hands, because expanded balloon 2 is stuck in patient's body, in the breather 1 outer process of drawing, backguy 6 drives pull bar 5 and rotates, in rotation process, the valve plate that the retaining of pull bar 57 one end withstand breather cheek valve door 3 overturns, and reaches detent position.Self-enclosed pneumoretroperitoneum balloon dilator of the present invention, 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.
