Problems solved by technology

[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 causes thickening of the inner wall of the gas delivery tube, which slows down the passing speed of the gas when it is ventilated again

Embodiment 1

[0027] as attached figure 1 To attach Figure 5 Shown:

[0028] The present invention provides an air pressure balanced puncture device, the structure of which includes an adapter 1, a balancer 2, and an air delivery tube 3, the balancer 2 is connected to the right end of the adapter 1, and the air delivery tube 3 is set on the right end of the balancer 2 middle part.

[0029] The air delivery pipe 3 is provided with a push plate 31, a push piece 32, a push spring 33, and a dredging device 34. The push plate 31 is installed on the inner wall of the left end of the air delivery pipe 3, and the push piece 32 is clamped between the push plate 31 and the air delivery pipe 3. Between the inner walls, the push spring 33 is fixed on the inner wall of the air delivery pipe 3 , and the dredging device 34 is located inside the air delivery pipe 3 and movably cooperates with the push spring 33 .

[0030] Wherein, the dredging device 34 is provided with a support ring a1, a limiting bl...

Embodiment 2

[0036] as attached Figure 6 To attach Figure 8 Shown:

[0037] Wherein, the push block s3 is provided with a connection plate e1, a reset block e2, a limit block e3, and a crushing plate e4, the connection plate e1 is located on the left side of the push block s3, and the connection plate e1 is movably matched by the reset block e2 , the limiting block e3 is embedded in the inner wall of the connecting plate e1, the crushing plate e4 is set on the inner wall on the right side of the connecting plate e1, and the reset block e2 is made of rubber material with elasticity, which is beneficial to the deformation and reset to drive the crushing plate e4 to vibrate , increase the cooperating driving force between the crushing plate e4 and the inner wall of the air pipe 3 .

[0038] Wherein, the crushing plate e4 is provided with a collection cavity r1, a connecting bar r2, and a clamping tooth r3, the collection cavity r1 is located inside the crushing plate e4, the clamping teet...

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...
