The utility model has the advantages of simple structure and convenient operation, and one person can quickly complete the expansion of the air bag with high expansion efficiency, which can effectively improve the operation quality, reduce the workload of the operator, and relieve the pain of the patient.

Description

retroperitoneal balloon dilator

technical field

The utility model belongs to the field of medical equipment, and mainly relates to a retroperitoneal air bag dilator.

Background technique

Laparoscopic technique has the advantages of clear surgical field of view, precise anatomical level, less damage, less bleeding and fewer complications, etc., and has been gradually applied in many clinical disciplines. Retroperitoneal laparoscopic surgery can quickly and directly enter the operation field, with less separated tissue, less damage, less impact on intestinal function, and quick postoperative recovery for patients. It also overcomes the limitation of application due to the past medical history in the abdominal cavity and avoids contamination of the abdominal cavity. and tumor growth. However, due to the small operating space in the retroperitoneal cavity, unobvious anatomical landmarks, and high requirements for the operator, it is difficult to complete the operation smoothly. In the clinical use of the existing retroperitoneal balloon dilator, it is necessary to inflate the syringe with one needle and one needle. Not only is the operation cumbersome, the injection needle is difficult to insert into the air inlet, but also the operation time is long, which brings a lot of pain and burden to the patient.

Utility model content

The purpose of this utility model is to provide a retroperitoneal balloon dilator aiming at the problems existing in the above-mentioned technologies. The device is simple in structure, easy to operate, high in expansion efficiency, can effectively improve operation quality, and reduce pain of patients.

In order to achieve the above object, the utility model adopts the following technical scheme: a retroperitoneal air bag dilator, including an expansion air bag and an inflation device connected by a vent pipe, and a one-way vent valve sheet is arranged in the vent pipe, and the one-way vent valve An air inlet pipe is arranged on the air pipe between the sheet and the inflatable device, an exhaust pipe is arranged on the air pipe between the one-way air valve sheet and the expansion air bag, and a one-way air inlet valve sheet is arranged in the air inlet pipe, and the exhaust air The mouth of the tube is provided with an exhaust piston.

The beneficial effects of the utility model:

The utility model has the advantages of simple structure and convenient operation, and one person can quickly complete the expansion of the air bag with high expansion efficiency, which can effectively improve the operation quality, reduce the workload of the operator, and alleviate the pain of the patient.

Detailed ways

As shown in Figure 1: the retroperitoneal air bag dilator includes an expansion air bag 1 and an inflation device 3 communicated by a vent tube 2, and the vent tube 2 is provided with a one-way ventilation valve sheet 6, a one-way ventilation valve sheet 6 and An air inlet pipe 4 is arranged on the air pipe 2 between the inflatable devices 3, an exhaust pipe 5 is arranged on the air pipe 2 between the one-way ventilation valve plate 6 and the expansion air bag 1, and a one-way air inlet pipe 4 is provided in the air inlet pipe 4. Air valve plate 7, the nozzle of exhaust pipe 5 is provided with exhaust piston 8.

During the use of the utility model, the expansion air bag 1 is first inserted into the posterior abdominal cavity of the human body, the exhaust piston 8 on the exhaust pipe 5 is closed, and the one-way ventilation valve sheet 6 and the one-way intake valve sheet 7 are placed in a closed state. After the device is stabilized, squeeze the inflation device 3, and the gas in the device will open the one-way ventilation valve sheet 6 and enter the expansion air bag 1, as shown in Figure 2; Negative pressure is generated in the air pipe 2, which forces the one-way intake valve 7 in the intake pipe 4 to open, and the inflator 3 pumps air, as shown in Figure 3; after the inflator 3 returns to its original state, the one-way intake valve 7 automatically closes , Squeeze the inflatable device 3, the gas rushes open the one-way ventilation valve plate 6 and enters the expansion air bag 1, and then repeatedly loosens and squeezes the inflatable device 3 until the expansion air bag 1 meets the surgical requirements. After the operation is over, open the exhaust piston 8 on the exhaust pipe 5 to discharge the gas, and take out the expansion air bag 1, and the use process of the device is completed.

The inflation device 3 can be an airbag device, a syringe device, or other devices capable of inflating.

The utility model has the advantages of simple structure and convenient operation, and one person can quickly complete the expansion of the expansion air bag 1 with high expansion efficiency, which can effectively improve the operation quality, reduce the workload of the operator, and alleviate the pain of the patient.
