Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a dual-channel laparoscopic irrigation and suction device. Background Technology

[0002] During open or minimally invasive surgery, the surgical wound may produce blood, pus, exudate, etc., resulting in an unclear surgical field. In order to carry out the surgery normally and restore a clear field of vision, it is necessary to use an irrigation suction device connected to saline to irrigate the surgical wound. After irrigation, the blood and water are aspirated out of the body. At present, the suction device connected to a negative pressure generating device is widely used in surgery. It has a suction function and its function is to remove the blood and water produced at the surgical site.

[0003] Existing disposable irrigation and suction devices achieve irrigation and suction through a single stainless steel tube. During suction, blood and water remain inside the stainless steel tube. During irrigation, the blood and water are flushed towards the surgical wound, which can easily cause blockage.

[0004] Therefore, it is of great significance to provide a dual-pathway laparoscopic irrigation and suction device to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a dual-channel laparoscopic irrigation and aspiration device to solve the problem that the existing disposable irrigation and aspiration devices achieve irrigation and aspiration through a single stainless steel tube. During aspiration, blood and water will remain inside the stainless steel tube, and during irrigation, the blood and water will be flushed towards the surgical wound, which can easily cause blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dual-channel laparoscopic irrigation and aspiration device includes a drainage housing, one end of which is connected to a stainless steel tube, and a flushing valve and an aspiration valve are installed on one side of the drainage housing. The flushing valve is connected to a flushing tube, and the aspiration valve is connected to an aspiration tube.

[0008] The stainless steel tube is provided with a metal movable valve inside. The head end of the metal movable valve is flush with the head end of the stainless steel tube, and the end of the metal movable valve protrudes beyond the end of the metal movable valve.

[0009] The cross-section of the metal movable valve is arc-shaped, and the convex surface of the metal movable valve is in contact with the inner wall of the stainless steel tube.

[0010] Preferably, the metal movable valve can deform inside the stainless steel tube. When the metal movable valve convexes upward, the concave surface of the metal movable valve and the inner wall of the stainless steel tube form cavity A. When the metal movable valve convexes downward, the concave surface of the metal movable valve and the inner wall of the stainless steel tube form cavity B.

[0011] Preferably, a sealing plug is threaded onto the symmetrical surface connecting the stainless steel tube and the drainage housing, and a lever is installed on the inner side of the sealing plug.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a movable metal valve inside a stainless steel tube. The movable metal valve can deform within the tube. When the valve bulges upwards, its concave surface and the inner wall of the stainless steel tube form cavity A. When the valve bulges downwards, its concave surface and the inner wall of the stainless steel tube form cavity B. During suction or flushing, the user can freely switch between cavity A and cavity B within the stainless steel tube without interference. Switching is easy: simply remove the sealing valve and move the protruding portion of the movable metal valve using a lever.
