Description

Single-hole renal cyst removes top decompression for operation gas abdomen closing device

Technical Field

The utility model belongs to the technical field of medical instrument, specifically a haplopore renal cyst removes a decompression for operation gas abdomen obturator.

Background

The renal cyst is a common disease and a frequently encountered disease of the urinary surgery, and with the development of minimally invasive technology and concept, the renal cyst operation is gradually developed from a porous laparoscopic operation mode to a single-hole operation, and the operation effect is similar, so that the trauma is reduced and the postoperative rehabilitation is accelerated. The conventional renal cyst single-hole surgical instrument is not provided with an outer sheath which can be matched with a balloon to use and can maintain a pneumoperitoneum surgical environment. The sheath matched with the existing balloon catheter can only be used for operation under the condition of continuous flushing of circulating water, gas cannot be sealed, cutting equipment mostly takes laser as a main part, and an electric hook and the like are also provided. In the current single-hole operation process, uninterrupted water flow flushing inevitably causes 'floating' of cyst walls, tension between tissues is lost, operation efficiency is reduced, and operation effect is even influenced; also, laser equipment is expensive and less efficient at cutting soft tissue. Therefore, the need is to develop and design a sheath which is used together with a balloon dilatation catheter, can seal gas and simulate the operation environment under pneumoperitoneum pressure, so that the cyst wall can be excised and devices such as an electric hook and the like can be used under the constant pneumoperitoneum environment, the price of the sheath is far cheaper than that of a laser device, the clear operation visual field is ensured, and the operation efficiency is increased.
