Description

A laparoscopic irrigation suction tube

technical field

The utility model relates to the technical field of medical devices, in particular to a laparoscopic irrigation suction tube.

Background technique

Laparoscopic surgery is a common surgical procedure and is widely used in clinical procedures. Among them, the suction tube is a common endoscopic device. Its function is to effectively remove the exudate, blood and irrigation fluid in the pelvic and abdominal cavity. It is a necessary device in endoscopic surgery. Especially for ectopic pregnancy hemorrhage, corpus luteum rupture hemorrhage or massive pelvic and abdominal effusion, the suction tube plays an important role. In clinical practice, the diameter of the traditional suction tube is beautiful, and there is a large amount of omentum and intestinal tube in the pelvic and abdominal cavity. During use, under the action of negative pressure, it is easy to cause the omentum and the wall of the intestinal tube to be sucked into the suction tube, resulting in suction. Efficiency is greatly reduced.

Therefore, we propose a laparoscopic irrigation suction tube.

Utility model content

The technical problem to be solved by this utility model is to overcome the defect of the above-mentioned technology, and provide:

A laparoscopic irrigation suction tube, comprising a first tube body, a second tube body, a ferrule and a control valve;

The first pipe body is connected with the control valve, and the first pipe body is provided with a sliding groove; the second pipe body is coaxially inserted into the second pipe body, and the second pipe body is far away from the control valve. One end of the valve is provided with a flexible expansion, and one end of the second pipe body close to the control valve is provided with a control rod, and the control rod is slidably matched with the sliding groove; the ferrule is coaxially sleeved on the The outer tube wall of the second tube body is slidingly matched with the second tube body, and the control rod penetrates the ferrule.

As an improvement, the first tube body and the second tube body are in sliding fit.

As an improvement, the flexible deployment is trumpet-shaped and spreads out to the surrounding.

As an improvement, the length of the sliding slot is greater than the width of the flexible expansion along the length direction of the first tubular body.

As an improvement, the end of the control rod is provided with a handle.

As an improvement, the control valve is provided with a flushing pipe connecting pipe.

As an improvement, an aspirator connecting pipe is provided on the control valve.

Compared with the prior art, the advantages of the present utility model are: the utility model can effectively avoid the greater omentum and the intestinal tube to effectively suction liquid during the operation, and avoid the suction caused by the greater omentum and the intestinal tube wall being sucked into the suction tube. Efficiency is reduced.

Detailed ways

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and "vertical" The orientation or positional relationship indicated by , "circumferential direction", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, construction and operation in a specific orientation, and therefore should not be construed as a limitation of the present invention.

In the description of the present invention, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature defined as "first" or "second" may expressly or implicitly include one or more of that feature.

A laparoscopic irrigation suction tube will be described in further detail below with reference to the accompanying drawings.

1 to 4, a laparoscopic irrigation suction tube includes a first tube body 1, a second tube body 2, a ferrule 3 and a control valve 4;

The first pipe body 1 is connected with the control valve 4, and the first pipe body 1 is provided with a sliding groove 5; A flexible expansion 6 is provided, and the end of the second pipe body 2 close to the control valve 4 is provided with a control rod 7, and the control rod 7 is slidably matched with the sliding groove 5; the ferrule 3 is coaxially sleeved on the outer pipe of the second pipe body 2 On the wall and slidingly matched with the second pipe body 2 , the control rod 7 penetrates through the ferrule 3 .

In this embodiment, as shown in FIGS. 1 to 4 , the first tube body 1 and the second tube body 2 are slidably fitted.

In this embodiment, as shown in FIGS. 1 to 4 , the flexible deployment 6 is trumpet-shaped and spreads out to the surrounding.

In this embodiment, as shown in FIGS. 1 to 4 , the length of the sliding groove 5 is greater than the width of the flexible expansion 6 along the length direction of the first tube body 1 .

In this embodiment, as shown in FIGS. 1 to 4 , a handle 8 is provided at the end of the control rod 7 .
