Abstract

The invention relates to a urinary system medical device, in particular to a retroperitoneal balloon dilator. At present, when retroperitoneal laparoscopic surgery is performed clinically, it is first necessary to establish an operating space. At present, surgeons mainly make preoperative gloves with gloves. However, self-made balloon dilators have too many disadvantages, resulting in an unsatisfactory operating space, which seriously affects surgical operations. The present invention is a retroperitoneal balloon dilator, comprising a balloon at the top with a length of 100-150mm and a diameter of 5-10mm. After the balloon is expanded, the volume can reach 400-1000ml; the bottom of the balloon is connected to a cylindrical hollow tube with a length of 200-250mm, diameter 5-10mm; the bottom is a conical gas injection valve, the length is 20mm, the diameter of the upper end is 10mm, and the diameter of the lower end is 5mm; there is a silicone plug inside the gas injection valve. The invention saves the operation time of doctors, optimizes the operation process and shortens the operation time. The invention has the advantages of simple structure, safe use and easy production, and effectively solves the technical problems encountered in the prior art.

Description

technical field [0001] The invention relates to a urinary system medical device, in particular to a retroperitoneal balloon dilator. Background technique [0002] At present, when retroperitoneal laparoscopic surgery is performed clinically, it is first necessary to establish an operating space, which is currently mainly made by the surgeon before the operation. However, the self-made balloon dilator has too many disadvantages, resulting in an unsatisfactory retroperitoneal space, which seriously affects the operation. Therefore, there is an urgent need for a device that can save operation time, simplify operation, facilitate use, and establish a good retroperitoneal space. Contents of the invention [0003] The present invention provides a retroperitoneal balloon dilator to solve the unsatisfactory establishment of retroperitoneal laparoscopic surgery space, reduce the cumbersome self-control work of surgeons, and shorten the anesthesia and operation time of patients at ...
