Problems solved by technology
[0004] The existing method for establishing an operating space and the equipment used have the following disadvantages: 1. Waste of manpower and time of the operator; 2. Due to the traditional method of gas injection, if the two operators are not skilled , can lead to inaccurate gas injection; 3. The patient is already under anesthesia at this time, which prolongs the time for establishing the operation space, and increases the risk of operation due to the prolongation of the operation time of the patient

The invention discloses a gas injection device for laparoscopic surgery. The gas injection device comprises a three-way gas injection pipe, wherein the three-way gas injection pipe comprises a gas injection pipe body; a first opening, a second opening and a third opening are formed in the gas injection pipe body; the first opening is provided with a first gas backstop unit, and the first gas backstop unit is used for being connected with an expansion gasbag tube; the second opening is provided with a second gas backstop unit, and the second gas backstop unit is used for injecting gas into thegas injection pipe body; the third opening is used for being connected with a gas suction unit. According to the invention, the gas injection three-way pipe is adopted; by operating the gas suction unit located at the third opening, gas can be continuously and rapidly injected into the three-way gas injection pipe from the second opening and then continuously and rapidly injected into a gas bag through a first outlet, so the steps of a gas injection process in the laparoscopic surgery are simplified, operation time is shortened, and the preparation time of a patient in a preoperative anesthesia state is shortened; and operation can be completed by one person, so manpower is reduced.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a gas injection device for laparoscopic surgery. Background technique [0002] During laparoscopic surgery in urology, part of the operation is performed in the retroperitoneal cavity or extraperitoneal space. These surgical areas that do not have any space space need to be opened and established by artificially injecting air bags at the beginning of the operation. Retroperitoneal cavity or extra-abdominal space, so as to better carry out the next operation. [0003] At present, most of the establishment of retroperitoneal or extra-abdominal space is completed by artificial self-made expansion balloon. The balloon is usually placed on the balloon tube with the middle finger or palm of the medical glove, then tied tightly with silk thread, and then 600-1000ml of gas is injected. . During the gas injection process, since it is a one-way pipeline, in order to prevent gas backflo...
