Detailed Description

The utility model will be further illustrated by the following description and examples, which include but are not limited to the following examples.

Examples

As shown in fig. 1 to 3, the surgical microscope camera interface disclosed by the utility model comprises a connecting seat 12 with a hollow interior, a connecting cylinder 13 which is in threaded connection with the connecting seat 12 and is vertically fixed on the connecting seat 12, an interface seat 15 which is fixed with the connecting cylinder 13 through a locking ring 14, an interface ring 16 which is fixed on the interface seat 15 and is used for connecting various camera devices, a reflector seat 1 which is arranged in the connecting seat 12 and is fixed right below the connecting cylinder 13, a reflector 2 which is arranged on the reflector seat 1, an objective lens component which is arranged at one end of the connecting seat 12 far away from the connecting cylinder 13, and a focusing component which is arranged on the connecting seat 12 and is focused by the objective lens component. Wherein, the installation angle of the reflecting mirror 2 forms an included angle of 45 degrees with the horizontal surface of the connecting seat 12.

In this embodiment, the objective lens assembly includes an interface cylinder 9 fixed to the connection base 12 by screws, a front cylinder 7 and a rear cylinder 4 disposed in the interface cylinder 9 and fixed together by screw connection, a front objective lens 8 fixed in the front cylinder 7, a rear objective lens 3 fixed in the rear cylinder 4, and a guide pin 11 fixed to the front cylinder 7 and connected to the focusing assembly.
