The utility model discloses the gasbag expander is located the inflator pump inboard and the external diameter is greater than the apron of through-hole external diameter and forms one-way valve in the through-hole position, thus the utility model discloses gasbag expander can effectively control gaseous business turn over inflator pump in the use, and then the high-efficient inflation of accomplishing the gasbag, and the device alone can accomplish the operation alone, convenient to use effectively practices thrift human cost and time cost; finally, the air bag inflation capacity of the air bag expander can meet the requirements of different required space establishment for operations.
Description
Technical Field
The utility model relates to a gasbag expander for posterior peritoneal cavity mirror operation.
Background
The viscera of urinary surgery are mainly positioned in the retroperitoneal space, the traditional open surgery is mainly operated by the retroperitoneal approach, since 20 th century 80 s, laparoscope is applied to urinary surgery, and Gaun in 1992 firstly proposes a method for establishing a retroperitoneal artificial lacuna, so that the operation of the laparoscope technology under the traditional operation approach is possible, the laparoscopic surgery is rapidly developed and popularized, the open surgery can be gradually replaced to a certain extent, and the laparoscopic surgery of urinary surgery has the advantages that: the incision is small, bleeding is less, trauma is small, the surface of the healed skin is relatively beautiful, postoperative risk is small, postoperative pain is light, recovery is fast, hospitalization time is short, the time for a patient to recover normal life and work is short, and intraoperative and postoperative complications are few and almost no long-term complications exist. In laparoscopic surgery, the surgery is performed through a small artificial channel, and when the channel is manufactured, the retroperitoneal space needs to be expanded and expanded by using an air bag, so that the surgery can be performed.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a gasbag expander which can be operated by one person and is convenient to use.
The technical scheme is as follows: the air bag expander for the posterior peritoneal cavity mirror operation comprises an inflator pump and a piston matched with the inflator pump; the air bag is characterized by also comprising an air bag, wherein an air inlet of the air bag is connected with an air outlet of the inflator through a connecting pipe; a closing switch is arranged on the connecting pipe; the inflator pump is provided with a through hole with a cover plate at the side of the air outlet, and the cover plate is positioned in the cavity in the inflator pump.
Wherein, one side of the cover plate is hinged with the side wall of the inflator pump; the outer diameter of the cover plate is larger than that of the through hole, and the cover plate rotates towards the inner cavity of the inflator pump through the rotating shaft.
Wherein, the closed switch is a valve or a polyethylene belt surrounding the periphery of the connecting pipe.
Wherein, the end part of the piston, which is positioned at the outer side of the inflator pump, is provided with a handle.
Wherein the volume of the inflator is 100mL.
Has the beneficial effects that: the utility model discloses the gasbag expander is located the inflator pump inboard and the external diameter is greater than the apron of through-hole external diameter and forms one-way valve in the through-hole position, thus the utility model discloses gasbag expander can effectively control gaseous business turn over inflator pump in the use, and then the high-efficient inflation of accomplishing the gasbag, and the device alone can accomplish the operation alone, convenient to use effectively practices thrift human cost and time cost; finally, the air bag inflation capacity of the air bag expander can meet the requirements of different required space establishment for operations.

Detailed Description
As shown in fig. 1, the balloon dilator for retroperitoneal laparoscopic surgery of the present invention comprises an inflator 1 and a piston 2 cooperating with the inflator 1; the end part of the piston 2, which is positioned at the outer side of the inflator 1, is provided with a handle 9, and the volume of the inflator 1 is 100mL; the air bag expander for the utility model also comprises an air bag 3, and the air inlet of the air bag 3 is connected with the air outlet 6 of the inflator pump 1 through a connecting pipe 4; a closing switch 5 is arranged on the connecting pipe 4, the closing switch 5 is a polyethylene belt surrounding the periphery of the connecting pipe 4, the middle part of the polyethylene belt is fixed on the connecting pipe 4, the polyethylene belt is manually operated, and the connecting pipe 4 is closed in a fastening mode; a through hole 10 with a cover plate 7 is arranged at the side of the air outlet 6 of the inflator 1, and the cover plate 7 is positioned in the inner cavity of the inflator 1; one side of the cover plate 7 is hinged with the wall of one side of the through hole 10; the outer diameter of the cover plate 7 is larger than that of the through hole 10, and the cover plate 7 rotates towards the inner cavity of the inflator pump 1 through rotation.
The inflator 1 is made of polyethylene, and the piston 2, the connecting pipe 4 and the air bag 3 are made of natural latex; the inflator 1 is cylindrical, when the inflator is used, the uninflated airbag 3 is sent into an abdominal cavity through a channel, the connecting pipe 4 is positioned outside the abdominal cavity, firstly, a polyethylene belt surrounding the periphery of the connecting pipe 4 is fastened tightly so as to clamp the connecting pipe 4, when the piston 2 is pulled outwards, suction is generated in the inflator 1, the cover plate 7 rotates around the shaft to the inflator 1, as shown in figure 2, and therefore air enters the inflator 1; when the piston 2 is pushed into the inflator 1, the gas pressure in the inflator 1 is increased, the cover plate 7 is closed on the through hole 10 to form a one-way valve, the polyethylene belt surrounding the periphery of the connecting pipe 4 is opened, the gas in the inflator 1 enters the airbag 3 through the connecting pipe 4, and as shown in fig. 3, the airbag 3 in the abdominal cavity is inflated through the operations.
