Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a contraction device for fixing a camera. Background Art

[0002] There are two ways to use the existing visual laryngeal mask with the camera assembly: the first way is to fix the camera assembly in the laryngeal mask and discard it together with the laryngeal mask after use, which has the problem of high cost. The second way is to use a camera channel in the laryngeal mask, and the front end of the camera channel is closed. The camera assembly reaches the observation position through the camera channel. The advantage of this method is that the camera assembly can be reused. At the same time, there are also disadvantages: the length of the camera channel of different specifications of laryngeal masks varies greatly. When using different specifications of laryngeal masks, it is necessary to select camera assemblies of different lengths for matching. If the length of the camera assembly is not selected properly, it may not be able to focus correctly, the picture is blurred, or the picture is reflected and the picture is abnormal.

[0003] At the same time, during use, the camera lens needs to have a pre-pressure on the laryngeal mask lens to make it fit together. However, in actual clinical use, the laryngeal mask will bend and deform according to the position of the human throat, causing the length of the camera channel to change. Sometimes the camera pre-pressure is insufficient and cannot fit completely, resulting in light leakage, which reduces the camera's observation range or makes it completely invisible. Sometimes the camera pre-pressure is too large and will damage the camera. Utility Model Content
