Embodiment 1

[0017] For electrosurgical surgery, laser and other types of surgery, which may cause less blood loss, the parameters of small suction flow are used:

[0018] A pneumoperitoneum real-time pressure-stabilized suction device for laparoscopic surgery, comprising a suction head 1 and a suction tube 2, and a suction mechanism 3 communicating with the two is arranged between the suction head 1 and the suction tube 2; the suction mechanism 3 includes a tubular shell body 4, the left end of the inner wall of the tubular housing 4 is fixed with a conical tube 5 whose diameter on the left side is greater than that on the right side; A number of air return pipes 7 passing through the side wall of the tubular body shell 4 and communicating with the abdominal cavity, each return air pipe 7 is provided with a one-way check valve core 8 and a filter plug 9 distributed inside and outside, and inside the tapered pipe 5 A gas-liquid separation plate 10 spirally distributed along its axial direc...

Embodiment 2

[0022] For ordinary scalpel surgery, which may cause a large amount of bleeding, the parameters of medium suction flow are used:

[0023] A pneumoperitoneum real-time pressure-stabilized suction device for laparoscopic surgery, comprising a suction head 1 and a suction tube 2, and a suction mechanism 3 communicating with the two is arranged between the suction head 1 and the suction tube 2; the suction mechanism 3 includes a tubular shell body 4, the left end of the inner wall of the tubular housing 4 is fixed with a conical tube 5 whose diameter on the left side is greater than that on the right side; A number of air return pipes 7 passing through the side wall of the tubular body shell 4 and communicating with the abdominal cavity, each return air pipe 7 is provided with a one-way check valve core 8 and a filter plug 9 distributed inside and outside, and inside the tapered pipe 5 A gas-liquid separation plate 10 spirally distributed along its axial direction is provided, a g...

Embodiment 3

[0027] For surgeries that require a large amount of fluid suction, the parameters that can generate the maximum suction flow are used for occasions that require a large amount of suction:

[0028]A pneumoperitoneum real-time pressure-stabilized suction device for laparoscopic surgery, comprising a suction head 1 and a suction tube 2, and a suction mechanism 3 communicating with the two is arranged between the suction head 1 and the suction tube 2; the suction mechanism 3 includes a tubular shell body 4, the left end of the inner wall of the tubular housing 4 is fixed with a conical tube 5 whose diameter on the left side is greater than that on the right side; A number of air return pipes 7 passing through the side wall of the tubular body shell 4 and communicating with the abdominal cavity, each return air pipe 7 is provided with a one-way check valve core 8 and a filter plug 9 distributed inside and outside, and inside the tapered pipe 5 A gas-liquid separation plate 10 spira...

Abstract

The invention in particular relates to a pneumoperitoneum real-time pressure-stabilizing suction apparatus for endoscopic surgery, for solving the problem that the surgery effect is influenced due todecrease of the pneumoperitoneum pressure during wound bleeding cleaning and seepage of the existing endoscope surgery. A suction mechanism is arranged between a suction head and a suction pipe; the suction mechanism comprises a pipe-shaped shell, a conical pipe is fixed at the left end of the inner wall of the pipe-shaped shell, an air collecting pipe is arranged at the right end of the conical pipe, air return pipes are radially arranged at the right end of the air collecting pipe, each air return pipe is provided with a one-way non-return valve element and an air filtering plug, air-liquidseparation plates are arranged in the conical pipe, an air collecting hole is formed in the center of each air-liquid separation plate, a plurality of liquid separating holes are formed in the side wall of the conical pipe, and the centers of the liquid separating holes are located on a helical line parallel to a helical line of the air-liquid separation plate. For the pneumoperitoneum real-time pressure-stabilizing suction apparatus for endoscopic surgery provided by the invention, air directly returns into the abdominal cavity of a patient, thus the loss of air in the abdominal cavity is greatly reduced, meanwhile, the efficiency of the endoscopic surgery is improved, and the surgical risk is reduced.

Description

technical field [0001] The invention relates to a medical device for minimally invasive surgery, in particular to a pneumoperitoneum real-time pressure-stabilizing aspirator for endoscopic surgery. Background technique [0002] Laparoscopic surgery has been rapidly promoted due to its small trauma and fast postoperative recovery, and has been widely used in general surgery and urology. During laparoscopic surgery, stable pneumoperitoneum pressure is the prerequisite and important guarantee for the smooth operation. The pneumoperitoneum pressure is usually inflated by a carbon dioxide insufflation machine and controlled by the surgeon to maintain the pressure within the range of 12 mmHg-16 mmHg. [0003] During the operation, in order to clean up the wound bleeding and exudate, a suction device is required, and the pneumoperitoneum gas will be sucked out at the same time during this process, resulting in a decrease in pneumoperitoneum pressure, which in turn deteriorates the ...
