Problems solved by technology

[0003] However, there are following defects in the suction system used in the existing laparoscopic (comprising laparoscope, thoracoscopic and inflatable mediastinoscope) surgery: (1) the negative pressure suction system that is always available in the operating room sucks liquid and discharges smoke, The carbon dioxide gas inflated in the body cavity will be quickly drawn out, causing the operating space inflated to shrink or even disappear immediately. The operation must be stopped, and the operation space can only be continued after the carbon dioxide gas is refilled to reach the specified pressure; (2) Suction and exhaust The smoke cannot be carried out continuously and effectively, the fluid in the operation site accumulates, and the lens is blocked by the smoke, resulting in unclear surgical vision; (3) The pressure in the body cavity cannot be adjusted and controlled during use, and the change is drastic
The above defects lead to the continuity and safety of the operation cannot be guaranteed

Embodiment 1

[0028] Such as Figure 1-4 As shown, the present invention discloses a constant pressure and adjustable discharge system for endoscopic surgery, which includes a suction device 1, a regulating tube 2, a waste liquid collection bottle 3 and a pressure regulating bottle 4, and a liquid 5 is arranged in the pressure regulating bottle 4. The upper end of the regulating tube 2 communicates with the upper end of the waste liquid collection bottle 3 through a hose 29, and the other end of the upper side of the waste liquid collection bottle 3 communicates with the suction device 1, so that the waste liquid in the body will flow into the waste liquid collection bottle 3 It falls to the bottom of the bottle under the action of gravity, so as to collect and measure the volume uniformly. The lower end of the regulating tube 2 extends into the pressure regulating bottle 4, and then the smoke gas flowing out from the waste liquid collecting bottle 3 will enter the pressure regulating bottle...

Embodiment 2

[0037] In this example, if Figure 5 As shown, what is adopted is that the liquid level of the liquid 5 moves up and down, and the regulating pipe 2 does not move. Wherein, the pressure regulating bottle 4 is provided with a liquid level regulating mechanism, and the liquid level regulating mechanism includes a slip joint sleeve 13 and Piston 14, the lower end of the sliding joint sleeve 13 extends toward the bottom of the pressure regulating bottle 4, the piston 14 is set to slide up and down along the sliding joint sleeve 13 to increase or decrease the liquid level of the liquid 5 in the pressure regulating bottle 4, the specific principle Yes: when the piston 14 moves downward, the piston 14 will discharge the liquid 5 in the sliding joint sleeve 13, and the liquid 5 will be discharged from the hole at the bottom of the sliding joint sleeve 13, thereby causing the liquid level in the pressure regulating bottle 4 to rise, and the same The regulating pipe 2 can be submerged i...

Abstract

The present invention discloses a constant-pressure and adjustable discharge system for endoscopic surgery. The constant-pressure and adjustable discharge system for the endoscopic surgery comprises an aspirator, an adjusting tube, a waste liquid collecting bottle and a pressure adjusting bottle, liquid is arranged in the pressure adjusting bottle, an upper end of the adjusting tube communicates with one end of an upper side of the waste liquid collecting bottle, the other end of the upper side of the waste liquid collecting bottle communicates with the aspirator, a lower end of the adjustingtube extends into the pressure adjusting bottle, an upper side of the pressure adjusting bottle is provided with a negative pressure interface, the liquid in the pressure adjusting bottle is relatively movable with the adjusting tube, and an air venting valve communicating inside and outside is arranged on the pressure adjusting bottle. Active suction and passive discharge can be freely converted;a discharge speed and an intra-abdominal pressure are stable, operators can conduct convenient and visual adjustment, thus the constant-pressure and adjustable discharge system greatly compensates shortcomings of existing aspirators in the endoscopic surgery and is more convenient and secure.

Description

technical field [0001] The invention relates to the field of medical surgical instruments, in particular to a constant pressure and adjustable discharge system for laparoscopic surgery. Background technique [0002] In minimally invasive surgery, it is usually necessary to fill a closed body cavity with positive pressure carbon dioxide gas to form a space for surgical operations. Among them, during the operation, it is often necessary for the suction system to suck various liquids such as blood and body fluids, and to discharge the smoke generated by energy devices (such as electric hooks, ultrasonic scalpels, etc.), so as to ensure a clear surgical field of view. [0003] However, there are following defects in the suction system used in the existing laparoscopic (comprising laparoscopy, thoracoscopic and inflatable mediastinoscope) surgery: (1) the negative pressure suction system that is always available in the operating room sucks liquid and discharges smoke, The carbon...
