Problems solved by technology

The current surgical retractor requires a large incision to enter the abdominal cavity, and the retraction operation is not easy to control
Originally, surgery is a very difficult job for the medical staff, especially for the operation in a place with a small space. Stretching and keeping it open for a long time puts higher demands on the physical strength of the medical staff and increases the difficulty of the surgical operation. Keeping the stretched state through the manual operation of the medical staff also reduces the consistency and safety of the operation

Abstract

The invention discloses a kidney-retroperitoneal-operation opening device. The kidney-retroperitoneal-operation opening device comprises an electric gas pump, a hand gas pump and a ball sac. The electric gas pump, the hand gas pump and the ball sac are connected to three ends of a three-way gas transmission tube respectively, one-way valves are arranged on two gas transmission tube sections connected with the electric gas pump and the hand gas pump, and a gas discharging valve port is arranged on one gas transmission tube section connected with the ball sac. According to the kidney-retroperitoneal-operation opening device, the ball sac capable of inflating and deflating is used as a main member of the opening device, and in the structure, the volume is small, and incisions entering the body can be reduced; due to a gas opening mode, harm to the human body is small, opening operation is easy, the opening state is easy to keep, the working strength of medical workers is reduced, and the consistency and the safety of an operation are also improved. The kidney-retroperitoneal-operation opening device is simple in structure, low in cost and good in application effect.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a retractor for renal retroperitoneal surgery. Background technique [0002] Currently, when operating on the kidney, the retroperitoneal cavity needs to be stretched. The incision required for the current operation to enter the abdominal cavity with a retractor is relatively large, and the retraction operation is difficult to control. Originally, surgery is a very difficult job for the medical staff, especially for the operation in a place with a small space. Stretching and keeping it open for a long time puts forward higher requirements on the physical strength of the medical staff, and also increases the difficulty of the surgical operation. Maintaining the stretched state through the manual operation of the medical staff also reduces the consistency and safety of the operation. Contents of the invention [0003] The object of the present invention is to provide...
