Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a carbon dioxide pneumoperitoneum tube with filtration and heating functions. Background Technology

[0002] A carbon dioxide pneumoperitoneum tube is an important instrument used in laparoscopic surgery to inject carbon dioxide gas into the abdominal cavity to establish and maintain pneumoperitoneum. By injecting carbon dioxide gas into the abdominal cavity, the abdominal cavity expands, separating the abdominal wall from the organs, providing sufficient operating space for surgeons to perform various laparoscopic surgical procedures, such as cholecystectomy, appendectomy, and myomectomy.

[0003] However, existing pneumoperitoneum tubes typically only require a threaded connection to the insufflator, which is not stable enough and the tube may come loose, affecting the surgery. Furthermore, if not properly stored after use, the tube can easily become tangled. To address these technical problems, this application proposes a carbon dioxide pneumoperitoneum tube with a filtering and heating function. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carbon dioxide pneumoperitoneum tube with filtration and heating functions. By rotating and screwing the pneumoperitoneum tube into the inner wall of the outlet tube, the first spring releases its elastic force to push the reinforcing slider to slide. The reinforcing slider is inserted into the outer wall of the outlet tube to reinforce the connection between the pneumoperitoneum tube and the outlet tube, preventing the pneumoperitoneum tube from becoming loose.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A slider is slidably connected to the outer wall of the pneumoperitoneum tube. A storage block is fixedly connected to the left side of the slider. A connecting rod is rotatably connected to the inner wall of the slider. A fixing block is fixedly connected to the outer wall of the connecting rod. The front side of the connecting rod is connected to the inner wall of the slider via an adjusting component to fix the connecting rod.

[0007] Furthermore, the limiting component includes a reinforcing slider that is slidably connected to the inner wall of the limiting groove, and the two reinforcing sliders are inserted into the outer wall of the air outlet pipe on the side of their proximity. Two first springs are provided inside the limiting groove.

[0008] Furthermore, one end of the first spring is fixedly connected to the right side of the reinforcing slider, and the other end of the first spring is fixedly connected to the right side of the inner wall of the limiting groove.

[0009] Furthermore, a limiting rod is fixedly connected to the inner wall of the limiting groove, and the inner wall of the reinforced slider is slidably connected to the outer wall of the limiting rod.

[0010] Furthermore, an adjusting block is fixedly connected to the top of the reinforcing slider, and a limit block is inserted into the front side of the reinforcing block. The two limit blocks abut against the side of the two adjusting blocks that are close to each other.

[0011] Furthermore, the adjustment assembly includes a limiting block slidably connected to the inner wall of the connecting rod, the front side of the limiting block being inserted into the front side of the inner wall of the slider, and a second spring being provided inside the connecting rod.

[0012] Furthermore, one end of the connecting rod is fixedly connected to the rear side of the limiting insert, and the other end of the second spring is fixedly connected to the front side of the inner wall of the connecting rod.

[0013] Furthermore, an adjustment button is slidably connected to the front side of the slider, and the rear end of the adjustment button is fixedly connected to the front side of the limiting block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating and screwing the pneumoperitoneum tube into the inner wall of the air outlet tube, the first spring releases its elastic force to push the reinforcing slider to slide. The reinforcing slider is inserted into the outer wall of the air outlet tube to reinforce the connection between the pneumoperitoneum tube and the air outlet tube, preventing the pneumoperitoneum tube from becoming loose.

[0016] 2. In this utility model, the insufflation tube is placed on the storage block by wrapping it around the tube, pressing the adjustment button, rotating the fixing block to limit the insufflation tube, and releasing the adjustment button to limit the insufflation tube, thus preventing entanglement when storing the insufflation tube.
