Abstract

The invention discloses an air pressure balanced puncture outfit. The air pressure balanced puncture outfit structurally comprises an adapter, a balancer and an air delivery pipe, the balancer is connected with the right end of the adapter, the middle of the right end of the balancer is sleeved with the air delivery pipe, and the air delivery pipe is provided with a push plate, a push piece, a push spring and a dredging device. As a small amount of blood flows back to the inner wall of the air delivery pipe, with the increase of operation time, blood is solidified on the inner wall of the airdelivery pipe, so that the inner wall of the air delivery pipe is thickened, a sliding block of the dredging device is matched with the inner wall of the air delivery pipe, and a scraping blade is used for removing the blood and reducing accumulation of the blood on the inner wall of the air delivery pipe, so that reduction of accumulation and solidification of the blood is facilitated, and smoothdelivery of air through the air delivery pipe is facilitated; and as blood clots coagulate on the inner wall of the air delivery pipe, the resistance of the inner wall of the air delivery pipe is easily increased, the blood clots solidified on the inner wall of the air delivery pipe are pushed and smashed through a pushing block, the resistance and friction force of the inner wall of the air delivery pipe can be reduced, the moving speed of the sliding block is increased, and the blood on the inner wall of the air delivery pipe is removed through the scraping blade.

Description

technical field

[0001] The invention belongs to the field of air pressure system equipment, and more specifically, relates to a puncture device with air pressure balance. Background technique

[0002] In surgical abdominal operation, in order to expand the surgical abdominal epidermis field of view, a trocar with air pressure balance is used to puncture the outside of the patient's abdominal cavity, and carbon dioxide gas is introduced through the trocar, and the carbon dioxide gas will stretch the abdominal epidermis; When the puncturer injects gas into the patient's abdomen, when the gas is stopped, the blood pressure of the epidermis is greater than the gas thrust inside the trachea, and a small amount of blood flows back to the inner wall of the trachea. As the operation time increases, the blood coagulates at The inner wall of the gas delivery tube thickens the inner wall of the gas delivery tube, and when the gas is re-ventilated, the passing speed of the gas is slowed...
