Technical Field

[0002] As we all know, mice are a common rodent, usually used in laboratory research. Usually, auxiliary devices are needed to separate mouse blood vessels. Usually, when separating mouse blood vessels, experimenters need to use auxiliary devices to help them perform minimally invasive surgery. In mouse blood vessel separation, the irradiation lamp provides sufficient light source to enhance the visibility, clarity and observation of subtle structures in the operation area, helping operators to accurately and finely locate and separate blood vessels, thereby improving the accuracy and success rate of the operation, reducing damage to animals, and ensuring the smooth progress of the experiment.

[0003] However, the irradiation lamp used in traditional mouse blood vessel separation auxiliary devices is usually fixed on a microscope or a bracket, and its height and angle are difficult to adjust. This fixed limitation restricts the operator from adjusting the position of the irradiation lamp as needed, making it impossible for the light to fully illuminate the area that requires operation, affecting the accuracy and efficiency of the operation. Therefore, technical improvements are urgently needed. Utility Model Content

The height of the lamp is adjusted according to the position of the operating table to ensure that the light can accurately irradiate the area where the operation is required, so that a clearer and brighter lighting effect can be provided, which helps researchers better observe and operate the target area and improves the precision and accuracy of the operation.
