Description

Technical Field

[0001] The utility model relates to the technical field of microscopes, in particular to a slit light source device with an operating space. Background Art

[0002] The slit lamp microscope is an important ophthalmic examination device. After decades of development, its examination functions as an ophthalmic examination device are almost perfect, especially its unique slit lamp, which is not available in other microscopes.

[0003] The traditional slit lamp microscope takes the following light source as an example, Figure 7 As shown, it includes a three-dimensional stage 10 and a three-dimensional arm 20. A microscope swing arm 30 is provided above the three-dimensional arm 20. A slit lamp swing arm 40 is provided above the microscope swing arm 30. A slit lamp 50 is fixed on the slit lamp swing arm 40. The rotation axes of the microscope swing arm 30 and the slit lamp swing arm 40 are coaxial with the vertical axis of the eye to be inspected on the surface of the eye to be inspected 9. At the same time, a subject support 60 for placing the head of the subject is fixed.

[0004] When using a traditional slit lamp microscope for an ophthalmic examination, the microscope independently swings along the vertical axis of the eye and around the eye in an arc shape. The slit lamp also independently swings along the vertical axis and around the eye in an arc shape. They each seek and establish the optimal angle for examining the eye. However, in actual use, traditional slit lamp microscopes still have the following shortcomings:

[0005] Using a slit lamp microscope to examine the eye can maximize the detection of problems. For example, a common intraocular foreign body, such as iron filings entering the eye, can be found quickly and accurately under a slit lamp microscope. It would be best if surgery could be performed immediately to remove the foreign body, but the slit lamp microscope does not have enough operating space. If a surgical microscope or head-mounted magnifier is used for surgery, it will be difficult to find the iron filings because the slit lamp is not available, which brings inconvenience to the surgery. For example, corneal ulcers can be clearly seen under slit lamp illumination, especially excitation light illumination. It would be best if debridement could be performed under this condition. However, the traditional slit lamp microscope has a small operating space, making corneal ulcer debridement difficult. This is because the slit lamp microscope is defined as an ophthalmic examination device, and only optical accessories such as a three-sided mirror and a front mirror can be held in front of the eye for examination. There is no operating space below the eye level. The operating space is occupied by the slit lamp and its swing arm, making it impossible to reach in for operation and the surgical instruments to turn.

[0006] Therefore, how to provide a slit light source device with an operating space for a slit lamp microscope to increase the operating space for examination, surgery and care of the eye under examination has become a technical problem that needs to be solved urgently. Summary of the Invention

The floating arc guide assembly comprises a floating arc guide rail, a U-shaped lower bolster, and a U-shaped upper bolster. The slit light source can slide left and right on the floating arc guide rail via the U-shaped upper bolster, to which the slit light source mount is fixed.
