Problems solved by technology

[0002] The lacrimal sac spreader is one of the indispensable and important surgical instruments in ophthalmology-related lacrimal sac surgery. The current lacrimal sac spreader is composed of a spreader mechanism composed of an adjusting screw, a forearm, a spreader connecting rod, and an arc-shaped hook. It is inconvenient to place and take out during use, and it will cause certain damage to the skin and subcutaneous muscle tissue, which will affect the incision suture after the operation.
At the same time, due to the small and deep field of view of the lacrimal sac surgery, the shadowless lamp is far away from the surgical field of view. In addition, the surgeon needs to peep at a close distance during the operation, and the head of the surgeon can also block part of the light, resulting in the obvious insufficient illumination of the deep surgical field of view, which seriously affects the operation. Operated by the operator, so the traditional ope

Embodiment approach

[0019] Another embodiment of the lighting device is: including a power supply 12, an electric wire 13 connected to the power supply 12, the electric wire 13 is placed in the hollow arc-shaped forearm 2, and the lighting bulb 14 is located in the forearm 2 near the end of the expansion piece 10, and the lighting bulb 14 Connect with wire 13.

[0020] The stretching piece is made of transparent materials such as plexiglass or metal materials, which play the role of bearing force. The lower edge of the spreading piece is slightly rolled up into a slightly hooked shape, and the hollow tube can be inserted into the optical fiber bundle. Or wires, the light from the cold light source is delivered to the head of the spreader through the bifurcated quartz light beam, and then shines into the deep part of the surgical field, so as to achieve good exposure of the surgical field and increase the illumination of the deep surgical field.

[0021] When in use, the present invention is place...
