Endoscope camera mounting structure and endoscope system

The utility model is applicable to the technical field of endoscope systems, and particularly provides an endoscope camera mounting structure and an endoscope system. The camera circuit board is arranged in the shell; the heat dissipation block is arranged in the shell; the camera circuit board is provided with at least one heat source; the heat sink is thermally connected to the housing and to the at least one heat source. According to the utility model, the camera circuit board and the heat dissipation block are arranged in the shell, and the heat dissipation block is thermally connected with the at least one heat source on the camera circuit board and is thermally connected with the shell, so that heat generated by the at least one heat source on the camera circuit board can be effectively conducted to the shell for heat dissipation, the temperature in the endoscope camera is reduced, and the service life of the endoscope camera is prolonged. The circuit board and the chip are prevented from working in a h
