Description

Technical Field

[0001] The utility model relates to the technical field of urology surgery, and more specifically, it relates to a water bag used for retroperitoneoscopic urology surgery. Background Art

[0002] Due to its minimally invasive advantages, laparoscopy is increasingly widely and deeply used in the field of urology. The surgical approach of retroperitoneoscopic urology is through the retroperitoneum. There is no natural space behind the peritoneum, and the space needs to be expanded artificially. The successful establishment of retroperitoneal space is the key condition for the success of retroperitoneoscopic surgery, which can avoid the risk of puncturing and damaging tissues and organs under blind vision. Using a water bag to expand the retroperitoneal space is a commonly used method in minimally invasive surgery. Medical staff use a cannula to insert the water bag into the abdominal cavity through the incision, and then inject saline to expand the retroperitoneal space. However, when injecting saline, the cannula will shake, which will collide with the incision and expand the incision. The incision needs to be sutured to prevent air leakage, which increases the workload. To this end, we propose a water bag for retroperitoneoscopic urology to solve the above problems.

[0007] When using a water bag for retrolaparoscopic urological surgery according to the technical solution, people inject saline into the bag through the water inlet pipe and the first one-way valve to increase the volume of the bag to support the retrolaparoscopy. At the same time, the device is designed as an integrated device to avoid leakage of saline. When taking out the bag, people connect the pumping device to the water outlet pipe, and with the cooperation of the second one-way valve, the saline inside the bag is pumped out to reduce its volume, so that it is easier to take out, which is safer and more convenient.
